Ex-NASA Employee Saw Hi-res UFO/Alien Craft Photos, Ready To Testify Before Congress

After the Pentagon‘s great UFO declassification and congressional hearings, NASA decided to hunt down the aliens. The agency possesses advanced technology on Planet Earth, exploring the possibility of transforming satellites into alien seekers to probe unexplained sightings without launching new equipment. The Galileo Project is designing a space mission to rendezvous with the next anomalous (Oumuamua-like) interstellar object that zooms into our solar system.

Is that the first time NASA became interested in alien civilizations? NASA whistleblowers, who claimed to have closely worked in some of the top missions, do not think so. Former NASA employee, Donna Hare reportedly saw a photo of a distinct UFO. Her colleague explained that it was his job to airbrush such evidence of UFOs out of photographs before they were released to the public.

On May 9, 2001, over twenty military, intelligence, government, corporate and scientific witnesses came forward at the  National Press Club in  Washington, DC to establish the reality of UFOs or extraterrestrial vehicles, extraterrestrial life forms, and the resulting advanced energy and propulsion technologies. As part of the Disclosure Project, Donna Hare, a photographic scientist testified to have worked for NASA contactor Philco Ford in the early 1970s. She had a high-security clearance to walk in NASA’s photo lab and other departments.

During the Disclosure Project press conference, Hare revealed that NASA covered up and eliminated space anomalies such as UFOs from the satellite photos. Hare has got several awards in the space programs. She dedicated most of her time as a technical illustrator to space programs. She created lunar maps and landing slides and had been working for 15 years as a sub-contractor for NASA.

Hare claimed to have had access to a place known as “Building Eight,” from where she made contacts with high-ranking officials. Once, she walked into a restricted area which was NASA’s photo lab. She noticed the lab had photographs of the Moon taken from satellites. She was with a friend who pointed at one of the photographs and surprisingly, she saw a round white dot.

“Good morning everyone! My name is Donna Hare, and I worked at Philco Ford aerospace from 1967 to 1981. During that time, I was a design illustrator draftsman. I did the launch slides, landing slides, and also projected plotting boards lunar maps for NASA. We were a contractor but most of the time, I worked in Building 8. I had the opportunity to do extra work during downtime which was between missions, and I walked into a photo lab which was the NASA lab across the hallway. I had a secret clearance which is not that high but I was able to go into restricted areas.

At the time, I was talking to one of the techs in there and he drew my attention to a NASA photograph. It had a “Dot” on it, and I asked what it was. Well, he drew my attention to it and I said is that a dot on the emulsion? He was smiling and he had his hands crossed… This was an aerial photograph of the Earth, I’m assuming the Earth because it had pine trees on it and the shadows of the craft or whatever it was were at the same angle as the trees and by its very nature, a UFO. And I wanted to clarify that to the gentleman that was talking to me… So, I did not know what this was but I realized at this point that it’s very secret.

I asked him what he was gonna do with this piece of information. He said they always airbrush these out before they sell them to the public, so they’re pissed pesky little creatures appearing on this photograph they wanted to get rid of. After that, I decided I would ask questions to other people that worked there (away from the site and not on site).

A guard told me that he was asked to burn some photographs and not to look at them, and there was another guard guarding him who was in green fatigues watching him burn the photographs and he said he was too tempted he looked at one.

I knew someone in quarantine with the Apollo astronauts he told me that the Apollo astronauts saw crap on the moon when we landed. He said that the astronauts are told to keep this quiet.”

Hare was told by one of the sources that during one of the moon landings, three UFOs had landed. Subsequently, there was a codeword “Santa Claus” for these crafts. She said she would be willing to testify before Congress. (Source)

In 2000, Gary McKinnon, a British Hacker who got so fed up with the government hiding information related to UFOs and free energy that he decided to hack the most secured servers of NASA and the Pentagon. McKinnon said that he had seen real photographs of UFOs in computer files at the  Johnson Space Center Building. He even took a screenshot of one of the cigar-shaped UFOs in-between space and the earth’s atmosphere. Unfortunately, it was removed from his computer after being seized.

Below is the recreation of the famous ‘NOT MAN MADE’ craft that was seen by McKinnon when he hacked & accessed NASA computers. (Source)

Now, scientists have learned that those aren’t the only massive lifeforms that dwell on Greenland’s ice, although new research is revealing how others have remained undiscovered for so long.

GREENLAND’S INVISIBLE “GIANTS”

Researchers studying Greenland’s icy ecosystem report the new discovery of gigantic viruses thriving on the region’s Arctic ice. These viruses could help manage local algal blooms and may even reduce the speed at which ice melts.

Lying dormant on the ice during the months, Greenland remains in darkness. As spring arrives, algae begin to bloom, causing large darkened areas on the ice sheet. This reduces the sunlight it reflects and induces faster melting, a process that could contribute to global warming.

Although they aBy extracting and sequencing mRNA from their samples, Perini and her team confirmed that viruses were present and living on the ice.

Unlike normal viruses, giant viruses can transcribe their DNA into mRNA themselves, whereas smaller varieties have to rely on hijacking the cells of their hosts. Many questions remain about these unusually large viruses, including what ecological roles they play and about their specific hosts.

Further studies are expected to reveal how these giant viruses interact in their Arctic ecosystem, and in the months ahead, Perini and her team plan to publish additional research on how these viruses infect microalgae, which could help to reveal new insights into the curious, “invisible” giants that thrive on the Greenland Ice Sheet.

Perini and her team’s paper, “Giant viral signatures on the Greenland ice sheet,” was published in the journal Microbiome in May.

Unveiling the US Government’s Secret Alien Interrogation Program: Jon Stewart’s Investigation

The idea of the U.S. government engaging in secretive programs involving extraterrestrial beings has long been a staple of conspiracy theories and speculative fiction. However, Jon Stewart, a former professional wrestler turned investigative journalist and political figure, claims to have uncovered evidence supporting the existence of such a program. Stewart’s meticulous investigation over two decades centers around an alleged interrogation of a Gray Alien captured on VHS tape from the early 1990s.

The Discovery and Investigation

In 1997, Jon Stewart stumbled upon a documentary featuring purported footage of an alien interrogation. This documentary, featuring a tan-colored Gray Alien experiencing apparent respiratory distress, captivated Stewart’s interest. Unlike typical Hollywood productions, the footage seemed unremarkable in its presentation, adding to its perceived authenticity. Intrigued by the casual nature of the video, Stewart sought expert opinions from video and animation professionals, all of whom failed to identify any signs of tampering or forgery.

Stewart’s quest for validation led him to consult with medical and military personnel allegedly involved in the interrogation. These interviews unveiled a narrative deeply intertwined with the clandestine activities of a faction within the military establishment, purportedly linked to the secretive S-4 facility within Area 51. The culmination of Stewart’s investigation led him to assert the authenticity of the leaked tape, believed to have been disseminated by an insider known as Victor.

The Whistleblower: Victor

Victor, a biologist employed by the Defense Intelligence Agency (DIA), played a central role in Stewart’s investigation. Victor’s responsibilities included managing the alien interrogation and retention program at S-2 Alpha, a facility south of Area 51. According to Stewart, Victor was the caretaker of six deceased Eban beings stored in glass tubes filled with liquid. His duties also involved educating dignitaries, military personnel, and scientists about the extraterrestrials and their preservation.

Victor’s revelations extended beyond his role at S-2 Alpha. He claimed to have interacted with high-profile figures such as Dick Cheney and Donald Rumsfeld, discussing the deceased aliens. Despite his efforts to bring this information to light, Victor expressed frustration in a 2008 documentary about the lack of interest from the ufology community in verifying his claims or the existence of S-4.

The Alien Interrogation Footage

The footage that sparked Stewart’s investigation depicted an alien being interrogated by intelligence officers through telepathic means. Medical personnel attended to the alien, which appeared to be in distress. The video included a digital overlay with the initials “DNI SL-27,” suggesting the involvement of the Department of Naval Intelligence (DNI). This department, although officially non-existent, was mentioned by a U.S. senator in a manner that reinforced the video’s credibility for Stewart.

The alien, described as a hybrid of organic and synthetic material, exhibited unique physical characteristics such as round eyes and a tan complexion, deviating from the typical portrayal of Gray Aliens. The being’s movements, described as mechanical and puppet-like, further fueled the authenticity claims, as these characteristics aligned with descriptions from other alleged encounters with Gray Aliens.

Speculations and Theories

Throughout his investigation, Stewart encountered various theories regarding the nature and origin of these extraterrestrial beings. One prevalent theory suggests that these aliens are interdimensional travelers capable of traversing space and time by bending the fabric of the universe. Others believe that the Grays are synthetic entities created by other extraterrestrial races to serve as scouts or explorers.

The motivations behind the alleged alien presence on Earth remain a topic of debate. While some experts speculate that these beings have benevolent intentions, others suggest a more ominous perspective, viewing them as demonic entities with a hidden agenda. This dichotomy of beliefs reflects the broader uncertainty and fear surrounding the extraterrestrial phenomenon.

The Government’s Stance and Implications

Stewart’s investigation raises critical questions about the U.S. government’s knowledge and involvement in extraterrestrial activities. The reluctance to disclose information and the alleged use of advanced alien technology to maintain global dominance suggest a complex web of secrecy. According to Stewart, the government’s monopoly on alien technology provides a strategic advantage, making the U.S. military 15 to 20 years more advanced than its global counterparts.

The potential benefits of alien technology extend beyond military applications. Innovations such as zero-point energy and advanced medical treatments could revolutionize various sectors, from energy to healthcare. However, the fear of losing control over these technologies and the societal upheaval they might cause has likely contributed to the continued secrecy.

Jon Stewart’s investigation into the U.S. government’s alleged alien interrogation program presents a compelling narrative that challenges conventional understanding. While the authenticity of the footage and the existence of such a program remain subjects of debate, Stewart’s findings underscore the need for greater transparency and openness in discussing extraterrestrial phenomena. As the quest for truth continues, the hope remains that one day, humanity will have a clearer understanding of its place in the cosmos and the potential interactions with otherworldly beings.

LIFTOFF! WATCH BOEING STARLINER’S HISTORIC LAUNCH THROUGH THESE 7 PHOTOS

An Atlas-class rocket hasn’t sent humans into space since the Mercury program’s final flight 61 years ago.

Astronauts Butch Wilmore and Suni Williams flew at 17,500 miles per hour northbound along the U.S. East Coast, towards Ireland, and over the Mediterranean Sea before entering orbit around Earth.

If Starliner aces the checks, docking with the International Space Station, reentry and landing in this next week, it will become the second U.S. human-rated spacecraft capable of ferrying astronauts into orbit.

Watch Wednesday’s historic launch, in pictures.

NASA/GETTY IMAGES NEWS/GETTY IMAGES

NASA astronauts Butch Wilmore and Suni Williams bid farewell to a crowd, which included their family and friends, by giving away flowers and tossing out mission patches. Astronaut Doug Wheelock (not pictured) was also in the crowd, taking video and photos for their families to remember the moment. Soon after, Wilmore and Williams boarded a van to reach the Boeing Starliner “Calypso” spacecraft for the Crew Flight Test launch.

The next step is certification. Williams and Wilmore will conduct a series of manual tests, and evaluate the performance of Starliner all the way through landing in the U.S. southwest in about one week.

Once Starliner is certified, NASA will have dissimilar redundancy in space, two different options to launch and return astronauts to and from humanity’s farthest human outpost.

The metal printer that is now on board the International Space Station employs stainless steel wire being fed onto the medium being printed upon. A high power laser which is a million times more powerful than a laser pointer then heats it up melting a small section. As the steel wire feeds into the melt pool it melts, adding to the metal, making it slightly raised. 

Unlike a 3D printer you may have (or I may be trying to justify) which you can control from your own computer, the printer on ISS is controlled entirely from the ground. The crew do have tasks however, they have to open a nitrogen and venting valve before the printing can start. I guess it’s almost the equivalent of putting the paper in your printer at home! 

The printer was developed by a team led by Airbus under the ESA Directorate of the Human and Robotic Exploration contract. It arrived on the ISS in January 2024 where the 180kg printer was installed in the ESA Columbus Module. 

The next step for the printer is to print four shapes that have been chosen for full-scale 3D printing. They will then be returned to Earth for analysis and comparison against reference prints already created in normal gravity. The teams hope to explore how microgravity impacts 3D printing. Two of the 3D printed parts will go to the Materials and Electrical Components Lab at ESTEC in Netherlands. The other two will go to the European Astronaut Centre at the Technical University of Denmark.

Within a single cubic millimeter of brain tissue are close to 57,000 cells, along with hundreds of synapses and blood vessels that, when reproduced in the Harvard and Google collaboration’s reconstructions, resulted in close to 1,400 terabytes of data.

The groundbreaking effort was led by Jeff Lichtman, Harvard’s Jeremy R. Knowles Professor of Molecular and Cellular Biology and newly appointed dean of science, offering an unprecedented glimpse at the intricacies of the human brain and its inner workings.

A decade in the making, Lichtman and the Google team’s research combines electron microscopy with Google’s advanced AI in a meticulous reconstruction of the complexities of the brain, as outlined in a recent scientific study by Lichtman, along with former Harvard postdoctoral researcher Alexander Shapson-Coe, Michał Januszewski of Google Research, and Harvard postdoctoral researcher Daniel Berger as co-first authors.

Now, the newly unveiled brain map, which the researchers call a “connectome,” has revealed what Lichtman recently characterized as “an alien world inside your own head.”

In the newly published study, the authors say the functions occurring within our brains represent the key difference that separates us from other life on Earth. Despite this recognition, we currently possess a less-than-complete understanding of the intricate synaptic circuitry underlying these functions.

Enter Google Research’s Connectomics team, which, over the last decade, has worked toward using machine learning to construct a clearer picture of the human brain at previously unmatched scales. The result of this work allows researchers to produce visualizations of extremely large volumes of neural circuits at high resolutions, which could lead to entirely new discoveries about the way our brains function.

A limiting factor in this research involves the problems with obtaining high-quality samples of human brain tissue. Unlike other organ biopsies, brain biopsies rarely occur except when used to extract neoplastic masses, which aren’t ideal for creating visualizations of normal brain structure. In past attempts, brain organoids composed of human cells have been used, but since they lack cortical layers, they were unable to faithfully reproduce all of the features of real human brain tissue.

In their recent paper, the study’s authors proposed a new strategy involving the use of human brain tissue extracted during neurosurgical procedures, which they said “could be leveraged to study normal—and ultimately disordered—human neural circuits.”

Lichtman obtained such a sample a decade ago. Smaller than a single grain of rice, the sample had been retrieved from the brain of a patient with severe epilepsy as part of a standard procedure where a small portion is removed to help reduce seizures and then analyzed to determine whether it is normal. Apart from the patient’s age and gender, Lichtman knew nothing else about the sample’s origins.

In their research, the team used electron microscopy to produce a massive set of very detailed images using this small piece of temporal cortex, which was only about 1 cubic millimeter in size. Then they analyzed the data with Google’s powerful AI, reconstructing thousands of neurons, over a hundred million synaptic connections, and other brain components like glial cells, blood vessels, and myelin.

The tremendous resulting trove of data, which revealed a previously unrecognized class of neurons hidden within deep layers of the tissue and “very powerful and rare multisynaptic connections between neurons throughout the sample,” was made available online, along with tools to aid other researchers in analyzing it. 

“This work provides evidence of the feasibility of human connectomic approaches to visualize and ultimately gain insight into the physical underpinnings of normal and disordered human brain function,” the researchers write in their new study. “It is hoped that this endeavor will be aided by providing free access to all of the data and relevant tools.”

“Given the enormous investment put into this project, it was important to present the results in a way that anybody else can now go and benefit from them,” said Google Research collaborator Viren Jain of the team’s findings.

Supported by the National Institutes of Health BRAIN Initiative, this collaboration’s ultimate goal is to create a high-resolution map of a whole mouse brain’s neural wiring. This ambitious project will require approximately 1,000 times the data produced from the current 1-cubic-millimeter fragment of human cortex used by Lichtman and his collaborators in the recent research.

The team’s landmark paper, “A petavoxel fragment of human cerebral cortex reconstructed at nanoscale resolution,” was published in the journal Science on May 10, 2024.

Afwijking

WASP-193b gaat voor nu de boeken in als de op één na minst compacte planeet die tot op heden is ontdekt; alleen de eerder gespotte – maar wel veel kleinere – Kepler-51d heeft een nog lagere dichtheid. “De extreem lage dichtheid (van WASP-193b, red.) is wat de planeet echt doet afwijken van de meer dan 5000 andere exoplaneten die tot op heden zijn ontdekt,” vertelt onderzoeker Khalid Barkaoui.

Barkaoui en collega’s vingen een eerste glimp op van WASP-193b dankzij de zogenoemde Wide Angle Search for Planets (kortweg WASP). Binnen dit onderzoeksproject wordt met behulp van een observatorium op het noordelijk halfrond en een observatorium op het zuidelijk halfrond de helderheid van duizenden sterren in de gaten gehouden. Daarbij werd ook gekeken naar WASP-193: de moederster van WASP-193b. En tussen 2006 en 2008 – maar ook tijdens aanvullende waarnemingen in 2011 en 2012 – zagen onderzoekers de helderheid van deze ster met regelmaat afnemen. Die afnames in helderheid bleken vervolgens te herleiden te zijn naar het bestaan van een planeet die rond WASP-193 cirkelde. Wanneer deze planeet – vanaf de aarde gezien – voor zijn moederster langs beweegt, houdt deze een deel van het licht van zijn moederster tegen, waardoor het lijkt of de helderheid van WASP-193 tijdelijk afneemt.

exoplanet, WASP-193B genoemd, is gevonden op een afstand van 1.232 lichtjaren.

Omlooptijd en omvang

Op basis van de metingen van WASP konden onderzoekers dus al concluderen dat WASP-193 een planeet bezat. Ook wezen de observaties uit dat deze ongeveer 6,25 dagen nodig had om een rondje om zijn moederster te voltooien. Daarnaast konden onderzoekers uit de hoeveelheid zonlicht die WASP-193b tegenhield op het moment dat deze voor zijn moederster langs bewoog ook afleiden hoe groot de planeet ongeveer was: ongeveer 1,5 keer groter dan Jupiter.

Massa

Opmerkelijk werd het echter pas toen de onderzoekers met behulp van andere observatoria ook de massa van de planeet poogden te achterhalen. Tot grote verrassing van de onderzoekers wezen deze aanvullende observaties namelijk uit dat WASP-193b een zeven keer kleinere massa heeft dan Jupiter. En daarmee heeft de planeet – die dus wel 1,5 keer groter is dan Jupiter – een zeer geringe dichtheid. Zo zou WASP-193b een dichtheid hebben van 0,059 gram per kubieke centimeter, zo is in het blad Nature Astronomy te lezen. Ter vergelijking: de dichtheid van Jupiter is 1,33 gram per kubieke centimeter en die van de aarde is maar liefst 5,51 gram per kubieke centimeter.

Suikerspin

“De planeet is zo licht dat het lastig is om een vast materiaal te bedenken (met een vergelijkbare dichtheid, red.),” merkt onderzoeker Julien de Wit op. Toch is het de onderzoekers gelukt; WASP-193b is qua dichtheid nog het beste te vergelijken met een suikerspin. Het bekende snoepgoed kent namelijk een dichtheid van ongeveer 0,05 gram per kubieke centimeter. “De reden dat (WASP-193b, red.) zo vergelijkbaar is met een suikerspin, is dat beiden in feite grotendeels uit lucht bestaan. De planeet is gewoon super fluffy.”

Waar een suikerspin vooral uit suiker bestaat, bestaat WASP-193b voornamelijk uit waterstof en helium, zo vermoeden de onderzoekers. Die gassen lijken een gigantisch omvangrijke atmosfeer te vormen die tienduizenden kilometers verder reikt dan de atmosfeer van Jupiter. Hoe de planeet zo is kunnen opzwellen, is onduidelijk. Wetenschappers hebben verschillende theorieën over hoe planeten ontstaan, maar geen enkele van die bestaande theorieën kunnen het bestaan van WASP-193b vooralsnog verklaren. “We kunnen niet verklaren hoe deze planeet ontstaan is,” bevestigt onderzoeker Francisco Pozuelos. “WASP-193b is een kosmisch mysterie,” voegt Barkaoui toe. De wetenschappers hopen dat toekomstige waarnemingen – met onder meer de James Webb Telescoop – kunnen helpen om dat mysterie op te lossen.

Around a star in our Milky Way galaxy, astronomers have discovered an extremely low-density planet that is as light as cotton candy. The new planet, named WASP-193b, appears to dwarf Jupiter in size, yet it is a fraction of its density.

CRE

The researchers behind the seemingly impossible find, which also includes experts from Belgium and Spain, say these types of “puffy Jupiters” have left astronomers baffled for over 15 years since they cannot explain how they formed using the best modern-day planet forecasting tools

“We don’t know where to put this planet in all the formation theories we have right now because it’s an outlier of all of them,” explained study co-lead author Francisco Pozuelos, a senior researcher at the Institute of Astrophysics of Andalucia, in Spain. “We cannot explain how this planet was formed based on classical evolution models.”

‘PUFFY JUPITER’ IS AS DENSE AS COTTON CANDY

According to a formal announcement of the discovery, WASP-193b was initially spotted between 2006 and 2008 and then again between 2011 and 2012. Those detections were made by the Wide Angle Search for Planets (WASP) project, which is a collaboration between international astronomers using a pair of robotic observatories in the southern and northern hemispheres.

Together, these robotic arrays of wide-angle cameras scour the stars, looking for the periodic ‘dips’ in light that sometimes indicate a planet is orbiting the star. In the case of WASP 193, a star located 1,232 light years from Earth, the southern WASP observatory spotted these types of dips during both recording sessions.

A detailed analysis of that data determined that a planet was likely crossing in front of its host star every 6.25 days. Further analysis of the amount of light blocked by the planet revealed that it was more or less similar in size to Jupiter. However, when astronomers tried to determine the planet’s mass by measuring how much it affected its host star’s orbit, known as the ‘radial velocity’ method, the numbers didn’t add up. In fact, their initial analysis found no shift in the star’s light spectrum at all, belying the planet’s massive size.

“Typically, big planets are pretty easy to detect because they are usually massive and lead to a big pull on their star,” said study co-author Julien de Wit, an assistant professor in MIT’s Department of Earth. “But what was tricky about this planet was, even though it’s big — huge — its mass and density are so low that it was actually very difficult to detect with just the radial velocity technique. It was an interesting twist.”

After reviewing the data and performing further analysis, the team determined that the planet was actually larger than Jupiter but had to be significantly less dense to exhibit so little gravitational pull on its host star.

“[WASP-193b] is so very light that it took four years to gather data and show that there is a mass signal, but it’s really, really tiny,” said lead study author and MIT postdoc Khalid Barkaoui.

The researchers say finding a solid material that has this type of limited density isn’t easy. In fact, in their published study, the authors say the best comparison they could make is that WASP-193b has the same density as cotton candy.

“The planet is so light that it’s difficult to think of an analogous, solid-state material,” Barkaoui says. “The reason why it’s close to cotton candy is because both are mostly made of light gases rather than solids. The planet is basically super fluffy.”

While clearly an outlier they cannot easily explain, the researchers say astronomers have seen similar readings in previous exoplanets. Still, those cases are still considered extreme outliers that don’t fit within planetary formation models.

“To find these giant objects with such a small density is really, really rare,” says lead study author and MIT postdoc Khalid Barkaoui. “There’s a class of planets called puffy Jupiters, and it’s been a mystery for 15 years now as to what they are. And this is an extreme case of that class.”

FOLLOW-UP OBSERVATIONS COULD UNRAVEL THE MYSTERY

In an effort to better understand the planet’s origin, the researchers say they are planning follow-up observations using a technique developed by de Wit. If successful, this process could reveal the planet’s temperature, composition, and even its pressure at various depths of what they suspect is a mostly hydrogen and helium atmosphere.

“Looking more closely at its atmosphere will allow us to obtain an evolutionary path of this planet,” Pozuelos said.

“The bigger a planet’s atmosphere, the more light can go through,” de Wit said in agreement. “So it’s clear that this planet is one of the best targets we have for studying atmospheric effects. It will be a Rosetta Stone to try and resolve the mystery of puffy Jupiters.”

Hoe rusten vogels tijdens lange overzeese migraties?

Door Janine

Trekvogels: hoe steken ze de oceaan over?

Wanneer de winter aanbreekt, maken trekvogels zeer lange reizen op zoek naar warmere omgevingen met voedsel, en keren dan de volgende lente terug. Maar heb je je ooit afgevraagd hoe ze reizen van duizenden kilometers over de oceaan doorstaan, zonder een plek om te stoppen om uit te rusten en te eten? Naast de merkwaardige V-vormige vlucht heeft een onderzoek het antwoord gevonden, en het gaat om een ​​“energiebesparende” techniek. In de praktijk maken vogels tijdens de trek gebruik van de wind tijdens de vlucht om de inspanningen te verminderen.

Ongeveer 40% van de soorten migreert elk jaar en vliegt in groepen van het ene continent naar het andere. Er zijn onderweg veel uitdagingen, vooral voor landvogels die lange tijd over open zee moeten vliegen. In tegenstelling tot zeedieren kunnen ze niet rusten en zich verfrissen met water, daarom kan hun vlucht geen pauzes bevatten. In theorie. Ornithologen waren van mening dat landvogels geen overtochten van meer dan 100 km konden ondernemen, omdat het niet mogelijk is lange afstanden af ​​te leggen door voortdurend met hun vleugels te klapperen, maar dat is niet het geval.

Energiebesparing dankzij wind en opwaartse druk

Volgens het Duitse onderzoek van het Max Planck Instituut en de Universiteit van Konstanz wordt de jaarlijkse trek over het water vergemakkelijkt door de atmosfeer: door gebruik te maken van wind en opwaartse druk slagen veel trekvogels op het land in deze prestatie en passen ze hun route zo nodig aan. Hoofdauteur Elham Nourani legt uit: "Tot voor kort werd gedacht dat opwaartse druk zwak of afwezig was aan het zeeoppervlak. In plaats daarvan ontdekten we dat trekvogels hun vliegroutes aanpassen om te profiteren van de beste wind en opwaartse kracht wanneer ze over zee vliegen. Dit helpt hen om hun vlucht honderden kilometers lang vol te houden”.

Het onderzoek omvatte de observatie van vijf verschillende soorten roofvogels die lange overtochten over zee maken: de visarend, de oostelijke honingbuizerd, de grijskopbuizerd, de Eleonora’s valk en de slechtvalk. Deze vogels hebben verschillende afmetingen, morfologieën en strategieën, maar de resultaten bevestigden dat het gebruik van rugwind is geoptimaliseerd om zowel tijd als energie te besparen tijdens de reis, naast de opwaartse druk. Het is echter niet helemaal waar dat vogels nooit stoppen tijdens hun inspannende reizen.

Maritieme migratie van vogels: tussenstop op schepen

Sommige landtrekvogels hebben rustplaatsen geïdentificeerd die worden gebruikt door volwassen vogels, die meer ervaring hebben met oversteken, en die door de generaties heen worden doorgegeven. Een studie ontdekte echter onverwacht dat veel soorten, veel meer dan eerder gedacht, schepen gebruiken om uit te rusten tijdens hun oceaanreizen. Men dacht namelijk dat boten slechts bij uitzondering als rustplaats werden gebruikt.

Tijdens een onderzoek in de Middellandse Zee werden gedurende vijfentwintig dagen dertien verschillende soorten waargenomen die de boot van de onderzoekers gebruikten als tussenstop. De tussenstop, oftewel de onderbreking van het vliegen, duurde gemiddeld slechts tweeënveertig minuten, waarschijnlijk door het gebrek aan voedsel op de boot. Desalniettemin voldoende tijd om te schuilen voor slecht weer en de batterijen op te laden. De gegevens die hieruit naar voren kwamen, suggereren verdere monitoring van de herfstmigratie boven het Middellandse Zeegebied en passerende boten: miljoenen vogels zouden het als rustplaats kunnen gebruiken.

Illinois Triangle UFO: The Shocking Police Encounter That Defies Explanation

On January 5th, 2000, a remarkable UFO sighting occurred over the state of Illinois near Scott Air Force Base, leaving multiple police officers and witnesses baffled. Known as the Illinois Triangle UFO sighting, this event involved detailed testimonies and audio recordings, providing substantial evidence of a massive, triangular unidentified flying object.

Initial Sighting

The first individual to notice the unusual occurrence was Melvin Null, a truck driver and owner of a miniature golf course in Highland, Illinois. Around 4:00 a.m., Null observed what he initially thought was a bright star in the northeastern sky. However, as he continued to watch, he realized that the light was moving towards him. Upon closer inspection, he identified the light as part of a large, rectangular object, roughly the size of a football field, with red lights underneath and several windows. Struck by the surreal sight, Null decided to report the incident to the local police.

Police Involvement

Highland police officers, initially skeptical, soon found themselves witnessing the object as well. Officers from various small towns maintained radio contact, sharing their observations. One officer reported seeing two bright lights that resembled car headlights, but significantly larger and brighter. Another officer noted that the object, which had initially appeared to be two lights, transformed into a single, intense light resembling a rising sun.

Officer Craig Stevens from Lebanon provided one of the most detailed accounts. He described the object as triangular, moving very slowly about 1,500 feet above the ground. As it approached his location, it suddenly accelerated to an incredible speed, covering a distance of six miles in just a few seconds—an estimated speed of Mach 10—without making any noise. Stevens also noted the object’s unusual ability to make flat turns, a maneuver inconsistent with known aircraft capabilities.

Detailed Descriptions

Officer Barton from Lebanon further corroborated these accounts, describing the object as an arrowhead-shaped craft, concaved at the rear with three large, bright lights that illuminated the entire sky beneath it. He noted that the object seemed to hover at a low altitude, moving slowly and silently.

Officer Martin from Shiloh observed the UFO from a different vantage point, describing it as having distinct, large white lights. Despite slight variations in descriptions, the consensus among the officers was clear: they had encountered a massive, silent, and inexplicably fast triangular object.

Radar and Military Considerations

The proximity of Scott Air Force Base raises questions about military awareness and radar detection of the UFO. Typically, radar systems might struggle to detect objects flying at low altitudes and slow speeds, as these characteristics are often filtered out to avoid confusion with birds or weather phenomena. However, once the UFO climbed to higher altitudes, it should have been detectable by military radar, prompting further investigation into why no immediate response was recorded.

The Illinois Triangle UFO sighting remains one of the most compelling and well-documented cases in UFO history. The credible testimonies of multiple police officers, all recorded in real-time radio communications, provide a strong case for the authenticity of the event. Whether it was a top-secret military craft, an extraterrestrial vehicle, or something else entirely, the Illinois Triangle UFO continues to intrigue and puzzle both skeptics and believers alike.

This extraordinary encounter invites us to question what we know about aerial phenomena and the capabilities of advanced technology, urging a deeper exploration into the mysteries that lie above us.

Steve, A Weird Ribbon of Light in the Northern Sky, Has A Twin

"Eh! Steve!"

BY KIONA SMITH

 

A Norwegian photographer, Gabriel Arne Hofstra, spotted the streamer of purple light in 2021 images from an all-sky digital camera at the Ramfjordmoen Research Station in Norway. ESA’s Swarm satellites, which study Earth’s magnetic field and how it interacts with the Sun’s electrically-charged solar wind, confirmed that Hofstra had found what the agency calls “something peculiar, something Steve-like.”

WHAT’S A STEVE?

When skygazers saw a ribbon of pale purple light in the night sky over Alberta, Canada in late 2016, they knew it wasn’t a normal part of the Northern Lights; auroras are normally green and sometimes red. Their ephemeral find was so baffling that it attracted the attention of researchers who study how Earth’s magnetic field interacts with the Sun’s electrically-charged solar wind. They gave the strange light a name fittingly shrouded in mystery and intrigue: Steve.

STEVE has since become an acronym for Strong Thermal Emission Velocity Enhancement. And a few months later, Steve turned out to be caused by a stream of extremely hot, electrically charged gas (or plasma) flowing swiftly across the upper reaches of Earth’s magnetic field.

A typical aurora happens when electrons collide with molecules in Earth’s upper atmosphere, releasing energy in the form of light. Those electrons usually arrive on the solar wind: streams of charged particles constantly blown outward by our Sun. They get caught in Earth’s magnetic field and ferried toward the poles, which is why you typically only see auroras at high latitudes.

Steve is a little different; it’s caused by a gas made of electrically charged atoms, not just tiny subatomic particles. Because of its different makeup, it gets caught on different magnetic field lines than the electrons that cause normal auroras. That’s why Steve shows up at lower latitudes. And unlike a normal aurora, which can last for several hours, Steve appears and disappears in a matter of movements.

The plasma that causes Steve gets very hot as it speeds along those magnetic field lines, causing a pale purple glow in the sky. Steve flows westward at dusk, and scientists monitoring Earth’s magnetic field quickly discovered another stream of plasma flowing eastward near dawn. But nobody had ever seen that second, eastbound plasma stream glowing the way Steve does — until recently.

Hofstra spotted the visible flow from Steve’s eastbound twin, and Swarm discovered that although the two auroral features are twins, they’re not identical twins: Steve usually appears a little south of the green Northern Lights, while Steve’s twin shows up closer to the North Pole. Both are long and thin: about 600 miles long and 15 miles wide, moving at more than 13,000 miles per hour.

Nobody has suggested a name for Steve’s twin – which is technically also a STEVE, but it’s so important for twins to have their own identities.

Haperende ruimtetelescoop Hubble werkt weer na aanpassing

De oude ruimtetelescoop Hubble kan weer aan het werk. De metingen van het observatorium waren vorige maand stilgelegd door een storing aan een van de gyroscopen. Die moeten ervoor zorgen dat de Hubble goed van positie verandert om het heelal in beeld te kunnen brengen. De Amerikaanse ruimtevaartorganisatie NASA denkt een manier te hebben gevonden om daarmee om te gaan.

De Hubble heeft in totaal zes gyroscopen aan boord. Die wieltjes draaien 19.200 keer per minuut om hun as. In 2009 zijn ze voor het laatst vervangen, bij de laatste onderhoudsbeurt van de ruimtetelescoop. Sindsdien zijn drie gyroscopen al uitgevallen en in de afgelopen maanden kreeg een vierde problemen. Die bleven terugkeren.

NASA heeft nu besloten om nog maar één gyroscoop te gebruiken. De Hubble wordt daardoor minder flexibel, hij heeft meer tijd nodig om te draaien. Maar de vluchtleiding denkt dat het leven van de ruimtetelescoop zo verlengd kan worden en dat hij tot in het volgende decennium nog kan werken.

De Hubble, gelanceerd in april 1990, had een verwachte levensduur van vijftien jaar, maar inmiddels draait hij al zo'n 34 jaar in een baan rond de aarde, op een hoogte van ruim 500 kilometer. Hij onderzocht onder meer afgelegen sterrenstelsels, waardoor wetenschappers een beter beeld hebben gekregen van het ontstaan van het heelal. Ook maakte hij beroemde foto's van verre nevels.

Als NASA de ruimtetelescoop aan zijn lot overlaat, kan hij ergens in de komende tien jaar langzaam uit zijn baan om de aarde zakken en uiteindelijk verbranden in de dampkring.

Omdat het einde van de Hubble nadert, is eind 2021 zijn opvolger gelanceerd, de ruimtetelescoop James Webb.

The team behind the tantalizing findings says that more follow-up analysis of the data is planned. However, their initial readings appear to be consistent with the presence of alien technology orbiting at least seven of these stars.

HOW TO SPOT ALIEN TECHNOLOGY LIKE A DYSON SPHERE

Since humanity’s most powerful telescopes cannot image objects orbiting distant stars directly, researchers Matías Suazo at Uppsala University in Sweden and Gaby Contardo at the International School for Advanced Studies in Italy knew they would have to analyze light spectrum data emitted by millions of stars across the galaxy to search for signs of alien technology. In the case of Dyson Spheres, the team would need to look for an ‘unnatural’ imbalance between the visible light and the infrared light emitted by a distant star.

That’s because, as proposed by Dyson, the more technologically advanced a species becomes, the more energy it needs. If they become advanced enough, a species could, in theory, surround an entire star with a “sphere” designed to capture all of its emitted energy. The Debrief previously covered the science fiction origins and viability of Dyson Spheres in 2021.

A fully completed Dyson Sphere would be almost impossible to detect from such a long way away since all of its visible light would be captured by the sphere. However, either an incomplete sphere or a swarm of satellites known as a partial Dyson Sphere or a Dyson Swarm would still allow some of the visible light through for Earth’s telescopes to capture. At the same time, the sphere would radiate an excess of heat energy in the infrared spectrum as it captures the star’s radiated energy and then releases it into space.

Suazo and Contrado proposed that if the ratio between visible light and infrared light coming off of any particular star is just right, it would represent compelling evidence for the presence of a Dyson Sphere.

ANALYSIS OF EXISTING DATA FINDS SEVEN TANTALIZING CANDIDATES

In their published study, which appears in the Monthly Notices of the Royal Astronomical Society, the researchers note that previous efforts dating back to the 1980s and as recently as 2021 have looked for this same type of light signatures coming from distant stars. However, they note that “none of these searches have revealed any strong candidates for Dysonian technology.”

Fortunately, the team says that advancements in modern space and ground telescopes may produce positive results; in fact, they believed that the data they were looking for may have already been collected by modern observatories and were just sitting there waiting for someone to go through it.

Specifically, the team hoped to find telltale signs of alien technology hiding in data captured by the European Space Agency’s (ESA) Gaia satellite, the Wide-field Infrared Survey Explorer (WISE) space telescope, and the ground-based infrared telescope survey MASS2.

“Dyson spheres, megastructures that could be constructed by advanced civilizations to harness the radiation energy of their host stars, represent a potential technosignature that, in principle, may be hiding in public data already collected as part of large astronomical surveys,” they explain.

Dubbed Project Hephaistos (named for the armorer of the Greek Gods), the effort would examine data from over one hundred million stars. Since that is too much data for humans to analyze, the team employed what they described as ‘neural network’ algorithms designed to measure and compare the visible light and infrared signatures emitted by the target stars. Notably, the team stayed away from what are termed “younger stars” since they may still have too much material in their orbits that could artificially skew the readings.

As hoped, the effort was a success. The customized algorithms not only found 60 stars that had the right light ratios, but seven of these were particularly tantalizing, with IR heat signatures that lacked any other good explanation. In fact, the signals were so strong that the team feared they might be young stars with large amounts of debris in their orbits.

To rule this out, the team searched for nearby X-ray sources. X-rays are “a powerful tool for tracing star-forming regions in the sky,” they explain, so if they found sources like this near any of the seven alien technology candidates, they could rule them out.

Luckily, the team says that the analysis came up empty. “After searching the XMM–Newton science archive, we found no evidence of X-ray sources in the neighborhood of our candidates that could be attributed to star formation.”

FOLLOW-UP OBSERVATIONS COULD CONFIRM DYSON SPHERES

In the study’s conclusion, the researchers indicate they have already performed a visual check of their seven Dyson Sphere candidate stars. Those tests seem to support their initial conclusions, with the researchers writing that “our visual inspection indicates that these sources are actual sources of infrared radiation that are not subject to any obvious contamination.”

Of course, Suazo and Contrado concede that much more analysis and follow-up observations are necessary to state with any measure of certainty that they have indeed spotted irrefutable signs of alien technology. They also note that although they tried to eliminate any other explanations, the sheer distance between Earth and the observed stellar candidates combined with our still-limited knowledge of the cosmos may mean there is a simple, natural explanation for the unusual light signatures they have found.

“We would like to stress that although our candidates display properties consistent with partial DSs, it is definitely premature to presume that the MIR presented in these sources originated from them,” the researchers write. “The MIR data quality for these objects is typically quite low, and additional data are required to determine their nature.”

They also concede that there are “several natural explanations for the infrared excess in literature,” However, they note, “none of them clearly explains such a phenomenon in the candidates, especially given that all are M dwarfs.”

Although the team is open to other explanations for their findings, Souza admits that “the most fascinating explanation could be actual Dyson spheres.”

By surrounding their star with swarms of energy-collecting satellites, advanced civilizations could create Dyson spheres.

Apollo Worker Found Evidence That Ancient Alien Cities Exist On Moon, NASA Fired Him

The mysteries around the Moon have been circulating after the first Apollo mission. Did the first crew really encounter the aliens there? First, many people still believe that NASA has never gone to Moon. But the majority strongly support the six lunar landing missions. In reference to the missions, NASA whistleblowers claimed that the agency is hiding the secret of artificial structures on the Moon. Among them, Dr. Ken Johnston claimed that NASA knows that astronauts discovered ancient alien cities and the remains of incredibly advanced machinery on the Moon. Some of these technologies can manipulate gravity.

Dr. Ralph Kennedy Johnston Sr was born at Fort Sam Houston US Army Air Corps Base in San Antonio, TX. in 1942. He was one of the four Civilian Astronaut Consultant Pilots at NASA who trained Neil Armstrong, Buzz Aldrin, and Michael Collins for the Apollo 11 Mission.

Additionally, Dr. Ken Johnston is a retired aerospace engineer, former active duty US Marine, and now known as “NASA Whistleblower.” He refuses the term “whistleblower” as he says what he did was providing the public with first-hand information that they deserve to know.

He refused to strictly follow orders and destroy a nearly-complete collection of 8″ x 10″ glossy photo prints from the Apollo program. These photos are not available from NASA at this time and are of a higher resolution than what is found online.

In the last 40 years, other scientists, engineers, and technicians have accused NASA of cover-ups and data withholding. There is a growing number of people who accuse the space agency of withholding information about anomalous space objects and lying about discovering artifacts on the surface of the Moon and Mars, denying evidence of life reported by the Viking probe in the mid-1970s.

According to Dr. Johnston, the Apollo astronauts brought back photographic evidence of the artifacts they found during their extravehicular activities on the moon. Johnston claimed that NASA ordered to destroy the EVA images at the  Jet Propulsion Laboratory ( JPL), but he refused. When he went public, he was fired from the agency.

In the 2007 press release, Kay Ferrari,  JPL’s Director of the SSA program, asked Dr. Johnston to resign. It was Johnston “being quoted [as] criticizing NASA in Hoagland’s new book, ‘Dark Mission,'” that prompted her to ask for Johnston’s resignation from the SSA Program. When Dr. Johnston refused, citing First Amendment protections of free speech afforded all NASA employees, even those at JPL, Ferrari apparently decided to remove him arbitrarily from the SSA Program, as stated in the press release.

After his abrupt departure, he indicated that he was tired of the US government sitting on evidence for more than four decades, evidence that ancient alien cities exist on the Moon. The low-quality pictures included in the book depict ruins of buildings, huge dome-like objects made of glass, stone towers, and castled hanging in the air.

“I have nothing to lose. I have quarreled with NASA and I got fired,” Ken Johnston said.

• Area 51 Scientist Before Death Made Shocking Confessions About Aliens, UFOs, & Anti-Gravity Tech

Dr. Ken Johnston’s Credibility

American space journalist James Oberg continued to attack Dr. Johnston despite he provided his credentials, certificates, and awards, including his doctoral certificate from the Reform Baptist Theological Seminary of Denver, granted in 1985.

Dr. Ken Johnston shared a document on his Facebook page where he stated that he was the substitute for the NASA Astronauts during the testing of the Lunar Module, better known as LTA-8 in Vacuum Chamber “B” at the Johnson Space Center. Source

From his ridiculous accusation that Dr. Johnston was not “in charge” of the photographs in his possession at NASA’s Lunar Receiving Laboratory, to attacking the doctorate itself, Oberg has been – inexplicably for a guy who says he wants to “move on to other things” – persistent. By his own account, Oberg had been burning up the phone lines trying to find something to discredit a man he had known for over 30 years while continuing to pretend he had never even met Dr. Johnston.

Otherwise, Dr. Johnston logged about 3,000 hours as a space pilot without ever going into space. As a test conductor, he helped train all of the Lunar Landing Mission astronauts to fly the Lunar Module.

When the first landing on the moon ended, about 30,000 employees were laid off because research and development were no longer needed, he said. After that, he became the Data and Photo Control Department manager at the Lunar Receiving Laboratory where he was responsible for controlling all of the data and photographic information generated from the Lunar missions.

Dr. Ken Johnston On Aliens

On his visit to Hindustan International School and University (India) in 2017, he shared a lot about the Apollo Mission and aliens with the New Indian Express. [Source]

 Do you believe that aliens exist?

– Yes. Don’t you? Your ancient history suggests that extraterrestrials came to our planet. Back in 1958, we unearthed proof that Eisenhower did meet with extraterrestrials. There is so much evidence not only to prove that there are aliens, but also that they have an impact on this planet.

– How did you develop an interest in aliens and space?

– Back in those days, I would watch series like Buck Rogers in the 25th Century and Flash Gordon. I wanted to go to space. My father was a pilot and I wanted to be one too.

– And then you went on to train Neil Armstrong.

– Not just Neil Armstrong. We were a team of four and our job was to test the lunar mission module in the vacuum chambers to ensure that the systems were safe to be taken to space. In the process, we trained Neil, Buzz and Michael to land it on the moon.

 What is your take on the ‘moon landing – faked’ controversy?

– (Laughs) We still have people who think that Earth is flat. Once a reporter told Buzz Aldrin that he didn’t go to the moon and he punched him. Even the latest satellite pictures show the same lunar footprints.

– How did you manage to get first-hand information about extraterrestrials?

– Once we were done with the first three missions, I was put in charge of photographing and documenting their exact location. One day, my boss ordered me to destroy these images. I reminded him that the government had paid for them and that they should be made public to which he replied, “No. Get rid of it. I don’t care what you think.”

– But why?

– Because there were elements in the pictures that were unexplainable. You can now download them for free from my website. You can see the lunar anomalies too. It looks like something has been smudged out. Way before Photoshop, they would paint things out.
Once, when I walked into the photo lab, I saw a woman painting something out. She called herself a ‘stripper’ and said that she was paid for it. This really upset me as I was in charge of keeping a record of things. I guess that’s why they call me a whistleblower.

– How transparent is NASA?

– People like me, who’ve gotten into trouble with NASA, have a different expansion for the acronym — Never A Straight Answer.

Significantly, the new findings also challenge past assumptions about these formation processes, a trend that has continued since Webb first began operating.

Using the telescope’s NIRSpec instrument during observations of three candidate galaxies at redshifts greater than 14, the research team involved with the study was able to perform deep measurements of the spectra generated from interactions between matter and radiation in these ancient star systems.

Selected from observations in a region of the Fornax constellation identified within the Great Observatories Origins Deep Survey (GOODS) south field, this grouping of galaxies was initially identified by the Hubble Space Telescope and Cycle 1 JWST/NIRCam data, which at the time pointed to a less than 1% chance that they were low-redshift “interlopers.”

Of the two galaxies, JADES-GS-z14-0 is the brightest and was found near a foreground galaxy, which introduced some initial complications in the team’s assessments. With time, Webb’s NIRCam observations of the region helped to dismiss the possibility of this premise, thanks to “additional deep medium-band NIRCam observations that substantially strengthened the case for the source being at high redshift,” the authors write in a new paper detailing their findings.

Detailed spectroscopy helped the team affirm the presence of a spectral line of hydrogen known as the Lyman-α break, placing the galaxies at redshifts of approximately 14.

After Webb’s NIRSpec camera also revealed that the faintest of the candidate galaxies had not been significantly detected, the team shifted their attention to JADES-GS-z14-0 and JADES-GS-z14-1, galaxies whose spectra showed a clear flux density break. This information also helped the team to confirm the high redshift of these galaxies.

Ultimately, redshifts of 14.32 for JADES-GS-z14-0 and 13.90 for JADES-GS-z14-1 were determined, revealing spectrographic signatures suggestive of very young stars and relatively low dust in these galaxies, which astronomers recognize as being traits associated with the early universe.

Additionally, JADES-GS-z14-0 appears to display a pronounced distribution of ultraviolet (UV) light when compared with other very bright galaxies, likely due to its size. The team says this points to a spatially extended stellar population, as opposed to a dominant active galactic nucleus (AGN), denoting the small region near the heart of many galaxies which is brighter than astronomers would expect to result from the luminosity of stars alone.

In some cases, the high luminosity of this central region can overpower the rest of the light generated by such galaxies. However, in the case of JADES-GS-z14-1’s UV emissions, the team involved with the new study says they appear to point to stellar rather than AGN dominance.

Another significant finding is that the masses of these galaxies appear to have grown rapidly from redshift 20 to 14, which is also suggestive of early star formation activity. This, along with the relatively low dust present in these galaxies, is believed to originate from a few possible factors that may include galactic outflows.

Ultimately, the discovery of these very early galaxies is providing compelling new data that points to the much earlier existence of these massive galaxies than many astronomers previously thought, although that isn’t to say that no one had expected such discoveries.

Still, such ongoing discoveries, made in large part with the help of the JWST, fundamentally support the reality that our existing notions about galaxy formation require a bit more work. With ongoing observations of the most distant and early regions of our universe, astronomers hope to deepen our understanding of the ‘Cosmic Dawn,’ where the first galaxies were born, in the years ahead.

The team’s new paper, “A shining cosmic dawn: spectroscopic confirmation of two luminous galaxies at z ∼14,” was uploaded to the preprint arXive.org server and can be read online.

For instance, last year’s workshop (AM IX) addressed the pressing question of whether NASA would be able to mount a crewed mission to Mars by 2033. This has been a key aspect of NASA’s Moon-to-Mars (M2M) mission architecture, detailed in the agency’s annual Architecture Concept Reviews (ACRs). It is also in keeping with Explore Mars’ goal of advancing the “human exploration of Mars and beyond no later than the 2030s.” Alas, in recent years, there has been growing skepticism that several key technologies will be ready to meet this deadline.

As Universe Today reported at the time, these doubts were raised at AM IX, and there was no consensus regarding potential solutions. This included the possibility of a flyby mission by 2033 and whether or not a nuclear-thermal propulsion (NTP) system, which can potentially reduce transit times to Mars (45 to 100 days), would be ready in time. In addition, there were the comments of Deputy Administrator Jim Reuters, who acknowledged that sending astronauts to Mars by 2040 was “an audacious goal for us to meet… It may sound like a lot, but it is [a] very short time to develop technologies we need to develop.”

As with previous AM workshops, cooperation and effective communication were emphasized. This includes coordinating robotic and human spaceflight missions and broader cooperation between space agencies, government, and industry. A key concern that was identified was the process through which NASA’s mission architecture evolves. While participants agreed that the M2M ADD “provides a strong starting point for an iterative architecture process,” they also concluded that the development process was insufficient. As stated in the AM X Report:

“Participants observed that despite recent progress, existing channels were insufficient to adequately integrate human capabilities and limitations as well as science objectives into the architecture development process. Similarly, sustainable human exploration of the Moon and Mars will not occur unless science and human exploration objectives are infused early and continuously into the systems engineering processes.”

To address these concerns, the workshop participants came up with four recommendations for improving existing channels and the architecture development process. They include:

Public Outreach & Involvement

First, the AM X Workshop Report recommended that public interactive forums be more frequent to develop inputs to NASA’s Architecture Definition Documents. The communities emphasized for engagement include operations, human research, science, international organizations, and others “that empower cross-disciplinary teaming, welcome broad participation from external experts, and provide a pathway to incorporate community recommendations and findings into Mars mission planning.”

The need to coordinate with diverse science communities to prioritize and narrow science objectives was also noted, as was the possible need for certification paths for external groups “to provide input in
smaller settings and more frequently than once a year at the ACR.”

The Report also emphasizes the need for initiatives and workshops that focus on the development and integration of “intelligent systems” and “data analytics” that will be critical for missions operating farther from Earth for extended periods. According to NASA’s mission architecture, this applies to Phase III of the Moon to Mars plan (aka. “Earth Independent”), where operations will shift from cislunar to deep space. This will include transits to and from Mars using the Deep Space Transport (DST) and science operations on the Martian surface.

Risk Mitigation

Second, the Report acknowledges the historical trend where certain priorities (like discovery science, technology, and infrastructure development) are often sacrificed for short-term needs. To this end, it is recommended that NASA acknowledge and address tensions between scientific investment for “risk mitigation purposes and investment for discovery science in planning for M2M missions.” While there is no reference to the sacrifices made to realize the Artemis Program and a return to the Moon by 2024, there are some hints that this could be the case.

The shifting priorities brought about by the expedited timetable have led to the deprioritizing of mission elements crucial to reaching Mars by the 2030s – like the Lunar Gateway. As acting Deputy Administrator Doug Loverro explained in March of 2020 during a NASA Advisory Council science committee, the Gateway was deprioritized to “de-risk” Artemis so NASA could focus on meeting the mandatory goals of Artemis and its 2024 deadline. Meanwhile, no design or feasibility studies have been performed for the DST or a Mars orbital habitat (a la the Mars Base Camp) since 2018/19, coinciding with the Artemis “shake-up.”

Regardless, the Report cites the need for increased funding to ensure “technology maturation, demonstration, and infusion to incorporate capabilities.” This is understandable, given that budget concerns have been an issue since NASA began planning missions to the Moon and Mars. In addition to speeding the development of technology, an increase in funding is also desirable to incorporate rapidly advancing technologies such as “artificial intelligence, data management, in-space manufacturing,” and others that are still relatively early in the development process.

Another important factor emphasized here is Health and Human Performance (HPP), which clearly refers to strategies for mitigating the health risks associated with deep space transits. These include extended periods spent in microgravity and long-term exposure to elevated levels of solar and cosmic radiation. To date, NASA has explored multiple possibilities for addressing these concerns, but no concrete plans have emerged just yet.

Evolving Architectures

Further to Recommendation I, the Report states that NASA and commercial companies invested in Mars exploration should continue designing “evolvable mission and campaign architectures.” The purpose of this is to allow for new technologies to be incorporated along the way and prevent the current state of technology from limiting plans. As per the Report, this will help ensure that “we do not design architecture and hardware applicable only for the first mission without allowing both to evolve for subsequent missions.” To this end, NASA and commercial industries are encouraged to:

• Develop common standards, requirements, and interfaces to allow the incorporation of multiple technologies, capabilities, and/or solutions as technology progresses over the next two decades.
• Create and implement a Human and System Readiness Level verification process to assess if the human, hardware, software, and planning systems are sufficiently mature as an integrated system.
• Ensure that the architecture is sufficiently flexible that it can address a wide range of missions beyond the first one.

Commercial Partnerships

Finally, the Report encourages NASA to continue investing and cooperating with commercial partners to realize lunar capabilities and technologies that will help them reach Mars. This goes to the heart of the M2M mission architecture, which prioritized a return to the Moon during the 2020s to develop the necessary technologies, systems, and expertise to create a pathway to Mars by the 2030s. “The Moon is how we learn to get to Mars,” it reads, “and we want companies thinking not just about getting to the Moon but, at the same time, how getting there prepares us for the more challenging missions to Mars.”

****

As usual, the prospect of sending crewed missions to Mars raised many concerns at this year’s workshop. This should come as no surprise, as the goal itself is incredibly ambitious and presents many major challenges. If there is a takeaway from this year’s workshop, it is that there is plenty of work to be done before a mission can be realized. This work must take place at the architectural level, emphasizing wider public engagement, advancing technologies, and a commitment to long-term goals.

In 2022, MSL Curiosity took an inventory of organic carbon in sediments at Gale Crater. Organic carbon is usually described as carbon atoms bonded covalently to hydrogen atoms and is the basis for organic molecules. The carbon in organic carbon can be either carbon-12 or carbon-13, and the amounts are important. At Gale Crater, Curiosity found about 200 to 273 parts per million of organic carbon. “This is comparable to or even more than the amount found in rocks in very low-life places on Earth, such as parts of the Atacama Desert in South America, and more than has been detected in Mars meteorites,” said Jennifer Stern, a Space Scientist at NASA’s Goddard Space Flight Center when the results came in.

This carbon is important evidence in understanding Mars’ history. It can tell scientists about the planet’s atmospheric processes and environmental conditions and even shed light on potential life. In fact, understanding Martian carbon can aid our understanding of habitability and prebiotic chemistry on distant exoplanets. The isotope ratio in this carbon is different than on Earth. It has a lower amount of carbon-13 relative to carbon-12 compared to Earth. Why the discrepancy?

In recent research in Nature Geoscience, a team of researchers tried to understand the difference between Earth’s and Mars’s carbon isotope ratios. The work is titled “Synthesis of ¹³C-depleted organic matter from CO in a reducing early Martian atmosphere.” The lead author is Yuichiro Ueno, a biogeochemist in the Department of Earth and Planetary Sciences at the Tokyo Institute of Technology.

“Strong ¹³C depletion in sedimentary organic matter at Gale crater was recently detected by the Curiosity rover,” the authors write. “Although this enigmatic depletion remains debated, if correct, a mechanism to cause such strong ¹³C depletion is required.” 

The amount of carbon-13 in the Martian sediments is far lower than in Earth’s sediments.

“On measuring the stable isotope ratio between 13C and 12C, the Martian organic matter has a 13C abundance of 0.92% to 0.99% of the carbon that makes it up,” lead author Ueno explained in a press release. “This is extremely low compared to Earth’s sedimentary organic matter, which is about 1.04%, and atmospheric CO2, around 1.07%, both of which are biological remnants and are not similar to the organic matter in meteorites, which is about 1.05%.”

The meteorite data is important because a four billion-year-old Martian meteorite named ALH 84001 is enriched in carbon-13, adding to the enigma of Mars’ carbon. Somehow, carbon-13 became depleted in the intervening billions of years. Solar escape is one possible reason for the carbon-13 depletion, but the authors discount that. There likely wasn’t enough time for enough carbon-13 to escape. “Furthermore, based on geomagnetic observations, early Mars probably had a geomagnetic field before 4?Ga,” the authors write. That field would’ve prevented solar escape.

To determine what’s behind this discrepancy, Ueno and his co-researchers simulated different Martian atmospheric conditions to see what would happen.

Their results show that isotope fractionation by solar UV light is responsible for Mars’ 13C depletion.

Carbon-12 and carbon-13 respond differently to UV light. Carbon-12 preferentially absorbs UV, which dissociates it into carbon monoxide that’s depleted in carbon-12. What’s left behind is CO2 enriched with carbon-13.

Scientists have observed this process in the upper atmospheres of Earth and Mars. In Mars’ reducing atmosphere, where oxygen was depleted, the CO2 enriched with carbon-13 would’ve transformed into formaldehyde and possibly methanol. But those compounds didn’t remain stable. In Mars’ early days, the surface temperature was close to the freezing point of water, and it never exceeded about 27 Celsius (80 F.) In that temperature range, the formaldehyde and other compounds could’ve dissolved in water. From there, they gathered in sediments.

But that’s not the end of Mars’ carbon isotope story.

The researchers used models to show that in a Mars atmosphere with a CO2 to CO ratio of 90:10, 20% of the CO2 would have converted to CO, leading to the sedimentary carbon isotope ratio we see today. The remaining atmospheric CO2 would be higher in C-13, and both values are in line with what Curiosity found, and with the ancient Martian meteorite ALH 84001.

This is a plausible scenario that can explain Curiosity’s curious carbon findings.

The team’s study also includes some other important details. For instance, atmospheric CO may not have come solely from photolysis by UV light. Some could have come from volcanic eruptions. And atmospheric CO may not have been the sole source of organics that found their way into the sediments. But either way, the results tell scientists something about Mars’ carbon cycle.

It also tells us to expect to find more organics in Martian sediments in the future.

“If the estimation in this research is correct, there may be an unexpected amount of organic material present in Martian sediments. This suggests that future explorations of Mars might uncover large quantities of organic matter,” said Ueno.

While the research shows us that life needn’t be present to produce these organics, it can’t rule life out. Nobody can, at least not yet.

The research also shows how complex atmospheric chemistry can be and how difficult it can be to draw conclusions from atmospheric studies of exoplanets. The JWST has examined several exoplanet atmospheres and found some interesting results. But there’s so much we don’t know. This research is a reminder that any conclusions are likely premature.

Robotische “derde duim” gemaakt om de grenzen van het menselijk lichaam te overwinnen en de bewegingsmogelijkheden te vergroten

Door Janine

Zijn twee duimen niet genoeg? Daar zorgt robotica voor

Dani Clode Design / The Plasticity Lab

Tien vingers in totaal, waarvan slechts twee duimen, is misschien niet genoeg, zelfs als we ons daar niet van bewust zijn. Gedreven door de overtuiging dat “meer beter is” wilden wetenschappers van de Universiteit van Cambridge de menselijke hand een extra verlengstuk geven. Robotisch natuurlijk. Deze sector wordt steeds populairder en ontwikkelt een reeks gemotoriseerde draagbare apparaten. Het doel? Door de grenzen van de menselijke anatomie te overwinnen en de motorische vaardigheden te implementeren die we nodig hebben om de prestaties te verbeteren, en om ondersteuning te bieden aan mensen met bewegingsproblemen.

Tamara Makin van de Cognition and Brain Sciences Unit van de Medical Research Council aan de Universiteit van Cambridge legt uit: “De technologie verandert onze definitie van wat het betekent om mens te zijn, waarbij machines steeds meer een onderdeel van ons dagelijks leven worden. Deze technologieën bieden opwindende nieuwe mogelijkheden waar de samenleving profijt van kan hebben, maar het is van cruciaal belang om te overwegen hoe ze alle mensen in gelijke mate kunnen helpen."

De robotiche derde duim: hoe werkt het

De Derde Duim, de specifieke naam van het apparaat, is ontwikkeld door Dani Clode, die meewerkt in het laboratorium van Makin. Het gaat om een extra robotische duim die de bewegingsmogelijkheden vergroot, waardoor zowel het grijpvermogen van de hand als de last die deze kan tillen en dragen toeneemt. Met andere woorden: het maakt het mogelijk om handelingen uit te voeren die met één hand moeilijk of onmogelijk zijn.

Het apparaat wordt aan de andere kant van de hand gedragen dan de natuurlijke duim en wordt bestuurd door een druksensor die onder de grote tenen wordt aangebracht. Druk van de rechterteen verlengt de robotische duim, terwijl druk van de punt van de linker grote teen deze dichter bij de vingers brengt. De kracht van de druk bepaalt de bewegingssnelheid, evenals de terugkeer van het apparaat naar zijn oorspronkelijke positie. Wetenschappers testten de Derde Duim in 2022 tijdens de Royal Society Summer Science Exhibition, waarbij enkele leden van het publiek betrokken waren die de kans hadden om het uit te proberen.

Inclusieve robotische duim: geschikt voor iedereen en eenvoudig in gebruik

University of Cambridge

592 deelnemers in de leeftijd van 3 tot 96 jaar waren in staat om de sensor gedurende vijf dagen te bewegen. Slechts vier deelnemers hadden hier echter moeite mee, omdat het prototype dat op de tentoonstelling werd gepresenteerd niet geschikt was voor de handgrootte van kleine kinderen, noch voor de sensor. In de overgrote meerderheid van de gevallen lukte het de proefpersonen om de duim te bewegen tijdens de minuut die beschikbaar was om hem te testen, geleid door de instructies van het team. De test bestond uit het oppakken van voorwerpen met alleen de Derde Duim, inclusief het oppakken van pinnen van een geperforeerd paneel en deze één voor één in de mand te verplaatsen, om er zoveel mogelijk te verzamelen binnen 60 seconden. Meer dan de helft van de deelnemers slaagde daarin.

Uiteindelijk was 98% van de deelnemers in staat om de objecten naar tevredenheid te verplaatsen, ongeacht verschillen in achtergrond en geslacht. Kinderen en ouderen toonden een vergelijkbaar vaardigheidsniveau, waarbij oudere volwassen deelnemers minder vaardigheid vertoonden vanwege hun leeftijd. Zoals Dani Clode uitlegde: "Gezien de diversiteit van lichamen is het cruciaal dat de ontwerpfase van draagbare technologie zo inclusief mogelijk is, zodat deze apparaten toegankelijk en functioneel zijn voor een breed scala aan gebruikers."

Astronomers Stumbled Upon A Rare Chance To Capture Just How Fast A Supermassive Black Hole Spins

One unlucky star brought fortune to these astronomers.

BY DORIS ELÍN URRUTIA

 

Back in 2020, astronomers noticed some strange activity. Using the Zwicky Transient Facility in California, they detected telltale signs that a star was going through what scientists call a tidal disruption event, in which an intense field of gravity rips a star apart. Tidal disruption events really only come from one thing: monster black holes. They realized what they were witnessing was a big black hole feasting on a star.

Astronomers observed the black hole in detail using the International Space Station’s NICER telescope, which is short for Neutron star Interior Composition Explorer. They found a few interesting details. Every 15 days, the supermassive black hole experienced a shift in X-ray intensity, and this pattern remained steady for the entirety of the four months they studied it.

From this, they were able to estimate the spin speed of the black hole. Finding such a specific detail about an object lurking roughly a billion light-years away is impressive. But the researchers say this new technique might be able to help solve some riddles about how the universe came to be. Specifically, how the hearts of galaxies evolved from Cosmic Dawn to today.

The supermassive black hole of the new study behaves somewhat like a kid swaying their hips to move a hula hoop. From the motion of the toy — in this case, the ring of shredded gas from the victim star — helped astronomers observe how the object’s intense gravity warps space-time to affect the disk. Black holes are so dense that not even light can escape them. But accretion disks around the black holes do emit light. They trace the path of this space-time warp. The black hole creates a drag called Lense-Thirring precession, and from this, astronomers deduced the spin speed.

This isn’t the first time that astronomers have derived the spin measurements of supermassive black holes and smaller black holes. But according to the lead author of the new study, MIT research scientist Dheeraj Pasham, this was the first time that the black hole’s warp of the space-time, paired with the luminosity of the accretion disk of an otherwise invisible object, led to finding the black hole’s spin speed.

The team owe much of their accomplishment to this black hole being a great candidate for study. It helped that the black hole was tilted towards Earth, letting astronomers investigate the X-rays clearly. NICER also has an easier job if it’s targeting objects in the direction of Earth’s poles, where the Sun can’t obstruct. The black hole is in the polar part of our sky, fortunately.

The spin speed of the black hole is a fingerprint. An abundance of slow-spinning black holes would mean frequent chaotic mergers between black holes — and the galaxies they reside in. “You’re dumping angular momentum in random orientations, and essentially spinning down the remnants,” Pasham tells Inverse.

“The other scenario is, let’s say you find most of the black holes are fast-spinning as close to the speed of light, that means they grew by accretion. Like a spinning top,” Pasham added. Over time, the balls of gas pulled in towards the black hole sped it up a little more.

This new research, along with discoveries emerging from a myriad of new telescopes taking flight soon, the universe’s history may not stay so hidden for long.
