NASA Stops Work on VIPER Moon Rover, Citing Cost and Schedule Issues

NASA Stops Work on VIPER Moon Rover, Citing Cost and Schedule Issues
NASA says it intends to discontinue development of its VIPER moon rover, due to cost increases and schedule delays — but the agency is also pointing to other opportunities for robotic exploration of the lunar south polar region.
The Volatiles Investigating Polar Exploration Rover was originally scheduled for launch in late 2023, targeting the western edge of Nobile Crater near the moon’s south pole.
The south polar region is a prime target for exploration because it’s thought to hold deposits of water ice that could sustain future lunar settlements. NASA plans to send astronauts to that region by as early as 2026 for the first crewed lunar landing since 1972.
Unfortunately, the VIPER project ran into a series of delays, due to snags in the testing and development of the rover as well as the Astrobotic Griffin lander that was to deliver the rover to the lunar surface. The readiness date for VIPER and Griffin was most recently pushed back to September 2025.
During an internal review, NASA managers decided that continuing with VIPER’s development would result in cost increases that could lead to the cancellation or disruption of other moon missions in NASA’s Commercial Lunar Payload Services program, or CLPS. NASA notified Congress of its intent to discontinue development.
The budgeted cost for building VIPER was $433.5 million, and the estimated cost of building and launching the Griffin lander is $235.6 million, according to a 2022 report from NASA’s Office of the Inspector General.
NASA said it will continue supporting Astrobotic’s Griffin Mission One, with launch set for no earlier than the fall of 2025. Instead of delivering VIPER, the mission would provide a flight demonstration of the lander and its engines. In January, Astrobotic’s Peregrine lander passed up an opportunity to land on the moon due to a problem with its propulsion system.
NASA said other missions could verify the presence of ice in the moon’s south polar region and determine how such resources could be used to further exploration goals.
“We are committed to studying and exploring the moon for the benefit of humanity through the CLPS program,” Nicola Fox, NASA’s associate administrator for science, said today in a news release. “The agency has an array of missions planned to look for ice and other resources on the moon over the next five years. Our path forward will make maximum use of the technology and work that went into VIPER, while preserving critical funds to support our robust lunar portfolio.”
Late this year, for example, Intuitive Machines is due to deliver an ice-mining experiment called PRIME-1 to the south pole under the terms of the CLPS program. PRIME-1 is designed to drill for water ice and study what happens to the H2O when it’s brought up to the surface.
In league with NASA, the CLPS program and a wide array of other partners, the Canadian Space Agency is planning to send an ice-hunting rover to the lunar south polar region by as early as 2026. The Artemis program’s crewed missions will also study the moon’s ice deposits and how they can be used.
NASA said it plans to disassemble VIPER and arrange for the reuse of the rover’s components and scientific instruments for other missions to the moon. But prior to disassembly, the agency said it would consider expressions of interest from commercial and international partners for use of the existing VIPER rover system at no cost to the federal government. Interested parties can email HQ-CLPS-Payload@mail.nasa.gov anytime between July 18 and Aug. 1.
NASA said the VIPER team would conduct an “orderly close-out” through next spring.
Word of VIPER’s demise was met with disappointment in some quarters of the space community. “In the Artemis era, why is lunar science targeted for cancellation?” Laura Seward Forczyk, founder and executive director of the space consulting firm Astralytical, asked in a posting to the X social-media platform.
Phil Metzger, a planetary physicist at the University of Central Florida, said NASA was making a “bad mistake.”
“This was the premier mission to measure lateral and vertical variations of lunar ice in the soil,” Metzger wrote in a posting to X. “It would have been revolutionary. Other missions don’t replace what is lost here.”
The internet is awash with videos appearing to show UFOs flying near high-speed planes, warheads and even nuclear reactors - and experts have an alarming theory for why these locations are being targeted.
In 1976, British Airways aired an ad for their Concorde flight in which an orb-like UFO darts toward the aircraft at an incredibly high speed, seemingly analyzes the plane and then accelerates away.
The unconfirmed UFO appearance - which has resurfaced on Reddit's UFOs subchannel, where alleged videos of craft are shared, debunked or given the upvote if they're deemed to be legitimate - is one of many that shows the odd, almost inquisitive behavior of these unknown objects.
In June 2022, at the Queen's Jubilee, the longest-serving royal monarch was honored by a cadre of nine fighter jets spewing streams of smoke in the Union Jack's red, white and blue colors — and one unidentified disc.
Despite it making the rounds on media, no clear answer has ever been provided as to what it was.

Even more curious is the nearly dozen UFOs that appeared above Japan's Fukushima lab after its nuclear disaster in 2011. Witnesses told the Netflix docuseries, Encounters, that the UFOs saved them by lowering radioactivity levels.
Local outlets caught several glimmering white orbs above the plant — extremely similar to the previous instances — dipping into the lab before emerging again, in a sort of assembly line.
In pop culture, the History Channel show The Secret of Skinwalker Ranch has features dozens upon dozens of similar UFOs over their five seasons, with many appearing after a rocket has been test-fired by their scientists into the air.
There has been a litany of explain-away reasons for these various occurrences provided by skeptics, from bugs to balloons. But for researchers who have dedicated their lives to this phenomenon, there is much more to theses videos than on their face value.
The question emerges: are UFOs approaching high-speed aircraft because they are concerned they contain nuclear capability?
Experts in the field have already analyzed similar behavior as proof that whatever is up there is concerned about us, especially when it comes to the prospect of blowing ourselves up with nukes.

UFO sightings over America's nuclear arsenal appeared to shift their interest from the making of the bombs to silos and bomber bases as the Cold War arms race grew (above)
UFO activity and nuclear devices and sites have been intertwined since the invention of the Atom Bomb in 1945. And the phenomenon been observed by civilians and military personnel alike.
'All of the nuclear facilities — Los Alamos, Livermore, Sandia, Savannah River — all had dramatic incidents where these unknown craft appeared over the facilities and nobody knew where they were from or what they were doing there,' investigative journalist George Knapp told History.com.
The former head of the Advanced Aerospace Threat Identification Program, Lue Elizondo, agreed that there 'seems to be a lot of correlation' between UFO appearances and nuclear sites.
And independent researcher Robert Hastings, who has been working toward full government disclosure of UAP activity, said in 2010, 'Declassified US government documents and witness testimony from former or retired US military personnel confirm beyond any doubt the reality of ongoing UFO incursions at nuclear weapons sites.'
Now, new research — in the form of three studies helmed by a retired US Air Force staff sergeant, Larry Hancock, and a data analyst affiliate with Harvard's UFO-hunting Galileo Project, Ian Porritt — shows that not only has there been unusual activity around nuclear weapons and facilities, it's shifted over the years.
At first seemingly interested in the production of nuclear weapons, UFOs later sprouted up around silos and bomber bases.
'You would see this interest' at silos when they were being installed before 'the activity would drop off,' Porritt previously told the DailyMail.com.
Independent researcher Robert Hastings (pictured), who has been working toward full government disclosure of UAP activity, said in 2010, 'Declassified US government documents and witness testimony from former or retired US military personnel confirm beyond any doubt the reality of ongoing UFO incursions at nuclear weapons sites'
These patterns in the historical UFO record, according to the researchers, was also accompanied by another clear trend: As the UFOs appeared more and more over armed and ready nuclear weapons sites, the apparent craft also started to appear more at night (above)
And when a new arsenal of ICMBs was built in the 1960s, UFOs became 'much more intrusive' in their approach of ICBM bases, Porritt said. 'They're very low altitude, they penetrate the security perimeters of the base.'
Two Air Force veterans previously told DailyMail.com they have testified to the All-domain Anomaly Resolution Office (AARO) in June 2023 that UFOs turned off their nuclear warheads.
On top of that, former US Air Force ICBM launch officer Robert Salas said he was contacted by the AARO in an email to gather information after he said he an orange flying disc shut off 10 warheads at Malmstrom Air Force Base in Montana in 1967.
Despite a thorough investigations by the military, no conclusion was drawn, but not before Salas said he was forced to sign an NDA on the matter by the Air Force Office of Special Investigations.
This echoes what former US Air Force First lieutenant Robert Jacobs said happened in 1964, when a UFO 'deactivated' an unarmed warhead in 1964.
Ex-First lieutenant in USAF Robert Jacobs, pictured middle bottom row, with his crew
'Now remember, all this stuff is flying at several thousand miles an hour. So this thing fires a beam of light at the warhead, hits it, and then it moves up… fires another beam of light… goes down and fires another beam of light, and then flies out the way it came in. And the warhead tumbles out of space,' he said in a 2000 interview.
Jacobs said he was later told to 'never speak of this encounter' again.
Eerily similar to these encounters are the instances of UAPs following fighter jets that were disclosed by the UAP Task Force, including a 'giant Tic Tac' UFO witnessed by Navy veteran fighter pilot Commander David Fravor in 2004.
Like the other craft pictured above, Fravor's fellow co-pilot Chad Underwood witnessed the 'perfectly white' wingless oblong that was captured from his cockpit's in-flight video.
Given the shared similarities, there seems to be a connection between the behavior of UFOs toward aircraft and nuclear weapons — and it may come from the very same reason.
UFOinvestigators claim to be in possession of unidentified material which tests show is of 'non-human' origin.
Tiny scraps of the sample — which is lighter than a flower petal and gold-tinged — were shown off for the first time this week at a conference in Irving, Texas.
MUFON, the UFO group in possession of the material, says that the sample has been tested using NASA-grade technology, which found it was 90 percent unidentifiable.
That means that it is either not a metal or a totally unknown metal different from all others in the periodic table, the researchers claim
Because of its unique light and porous texture, MUFON has floated the idea that the sample resembles 'debris from a craft' — after the Russian researcher who obtained the sample claimed it might be the remnants of a crashed UFO.
But independent UFO experts have questioned the find, saying that it's just the latest in a long line of samples which 'could be of alien origin,' but then turn out not to be.
MUFON researcher Bob Spearing claims the material conforms to nothing known in tests
Investigators showed off tiny scraps of the material, in a presentation at the MUFON International Symposium.
The group claims that further samples were stolen from an official US Post Office Box, after the sample's Russian finder attempted to mail them to MUFON in the U.S..
'This is typical with evidence of this nature,' MUFON Media Relations Director Ron James said.
'We believe that this material was deliberately taken by someone who could hack into a locked Post Office Box to prevent further testing.'
'Who did it is anybody's guess,' according to James.
MUFON researcher Bob Spearing told symposium attendees that he had been approached by a Russian researcher, named Arkady, who said that he had tested the material with Russian geological labs using an X-Ray fluorescence gun.
'It's very, very light material,' Spearing told attendees. 'It almost looks porous, like it has pores. It has a tinge of gold in it, but it's basically a black material. Seems to be some sort of composite.'
'It's so light,' he added, 'that it won't even bend a flower.'
The 'metal' is so light it doesn't even bend a flower
A small sample of the metal
Arkady, the Russian researcher who provided the sample, claimed that the material had 'appeared' in his house after he was contacted by a non-human entity who told him it had come from a crashed UFO.
Later, Russian labs found that the mysterious material was composed of 10-percent calcium, titanium, iron, arsenic and copper, according to Spearing.
This is a tantalizing but inconclusive finding given the mixed reliability of such handheld X-Ray fluorescence (hXRF) devices in identifying the chemical make-up of test samples.
Geologists looking to identify the chemistry of rock formations out in the field, environmental regulators tasked with assessing pollution in soil samples, and even pawn brokers testing jewelry have turned to X-Ray fluorescence guns in recent years.
The devices have offered speed, portability and a noninvasive method for examining the composition of a material that does not destroy that material in the process.
But researchers have also frequently reported on the technology's limitations.
One group of environmental scientists in Arizona, for example, reported last year that their portable X-Ray fluorescence tests failed to accurately identify chromium metal content, due to high iron content drowning out the chromium's signal.
And NASA scientists who helped to prepare for the 2020 Mars Perseverance rover's mission found that their own X-Ray fluorescence guns proved unable to detect some key elements 'reliably.'
'While this limits the use of the hXRF, especially when compared to laboratory XRF techniques,' those NASA researchers reported, 'hXRF is still capable of providing the field user with significantly improved contextual awareness of a field site.'
Spearing told the symposium that some of Arkady's 90-percent unidentified materials were also shipped to MUFON's lab in Missouri, which found that the sample didn't match up to known metals using another X-Ray fluorescence test.
'That either means it's A) not a metal, or B) a metal alloy that isn't recognized or something in the periodic table,' Spearing said.
'The signal was unique, because they have looked up the standard peaks for most known metals, and nothing matched it exactly,' he continued.
'By appearance only. It appears to be some sort of lightweight insulation suited to conductive insulating or something needing heat protection, which could correspond to it being a piece of debris from some sort of craft,' he concluded.

But the plot thickened when Spearing asked a colleague to send him the sample via post — where it appeared to be stolen from Spearing's USPS mailbox.
Cameras had been turned against a wall, inhibiting investigation, although US postal workers testified that they did delivered the box.
'I went to my mail clerk and said, "Was it delivered?"' Spearing explained. 'And she said, "Yes, Bob, it was delivered. I put the box in your mailbox myself."'
'So the question becomes, who would be daring enough to remove something from a federal mailbox?' he asked.
Fortunately, the UFO researchers were able to obtain another sample from Arkady, which arrived after sitting in Customs for 17 days.
MUFON stated that the sample will now be sent to two further labs for testing using electron microscopes.
'We have physical materials and more evidence of non-human technology,' James said.
MUFON, short for the Mutual UFO Network, is the largest and oldest civilian UFO research organization in the world.
Active since the late 60s and dedicated to 'the scientific study of UFOs for the benefit of humanity,' MUFON is now a worldwide network of like-minded citizen-investigators with members in all 50 US states.
Not everyone — even among diehard UFO investigators — was convinced by Spearing's presentation, however.
UFO author Nigel Watson, author of Captured by Aliens? A History and Analysis of American Abduction Claims told DailyMail.com that the 'evidence' is just one in a long line of supposed 'debris' from spacecraft which turned out to be nothing of the sort.
'There is a regular flow of 'new' physical evidence to prove cases like the Roswell crash case,' Watson told DailyMail.com.
'Everything so far submitted is usually explained when scientifically examined,' in Watson's view. 'It is all a matter of unrealistic hope versus actual facts.'

The Secret of Skinwalker Ranch Season 5 finale Tuesday, July 23rd, 2024 on The History Channel!
I just had to focus this alien cross shaped base with ai and wow...ai didn't let me down. This structure just popped! The structure looks to be 2.5-3.5 miles across and it has a dark black jewel roof at its center with what looks like white ribbon on its top. AI is the new tech of the future, we either embrace it or we fall behind.
I found a large X or cross structure on the moon. The area is broken up into sections, but clearly each section makes up a part of the cross. Not far away I found many other structures of odd shapes and sizes. I found that this old photo from which this came was taken long before photoshop existed, therefore it remained unedited. If you click on the non official source (1st link) it works fine, but if you click on the official NASA link below it, you will find a NASA page with old lunar photos...of which all the links have been destroyed. NASA took the information from my site in 2015 and used it again, yes I said again, to edit their photo index. At the moment is says, "Service unavailable." It always says that. They are keeping vital information about aliens from reaching the public and from reaching the governments of other countries. Scott C. Waring
Dergelijke tunnels onder het maanoppervlak zouden zomaar eens uitstekende verblijfplaatsen voor mensen kunnen zijn.
NASA en andere ruimtevaartorganisaties hebben al geruime tijd plannen om de maan te koloniseren. Het doel is om er een permanente basis te vestigen waar mensen langdurig kunnen verblijven. Dit biedt de mogelijkheid om essentiële kennis en ervaring op te doen die nodig is voor toekomstige missies naar Mars. Een cruciale vraag is echter: waar moeten toekomstige maankolonisten precies gaan wonen? Bestaan bijvoorbeeld de lang besproken ondergrondse maangrotten echt? Een nieuwe studie biedt nu duidelijkheid.
Lavatunnels Het idee om onder het oppervlak van de maan te gaan wonen, wordt al lange tijd overwogen. Onderzoekers denken daarbij vooral aan lege lavatunnels. Dat heeft namelijk belangrijke voordelen ten opzichte van het bouwen van een basis op het oppervlak. Deze tunnels bieden astronauten bescherming tegen kosmische straling, zonnestraling en micro-meteorieten. En dat is geen overbodige luxe. Kosmische en zonnestraling op het maanoppervlak kunnen namelijk tot wel 150 keer sterker zijn dan wat we op aarde ervaren. Bovendien blijft de temperatuur in deze tunnels stabiel, zonder de dagelijkse variaties die op het oppervlak voorkomen. En ook dat is prettig. Aan de verlichte zijde van de maan kunnen de oppervlaktetemperaturen namelijk oplopen tot een verzengende 127 graden Celsius, terwijl ze aan de onverlichte zijde kunnen dalen tot -173 graden Celsius. Daarnaast liggen deze grotten vaak dichter bij bronnen van waterijs en andere essentiële mineralen die nodig zijn voor langdurig verblijf. Hoewel dit allemaal veelbelovend klinkt, was het tot nu toe nog onduidelijk of dergelijke ondergrondse maangrotten echt bestaan.
Meer over lavatunnels Lavatunnels kunnen op twee verschillende manieren ontstaan. Wanneer lava met een lage viscositeit (stroperigheid) vrij dicht onder het oppervlak stroomt, kan boven de lavastroom een harde – en steeds dikker wordende – korst ontstaan. Die korst vormt als het ware een dak waaronder het gesmolten deel van de lava stroomt. Wanneer de erupties ten einde komen en al het lava is weggestroomd, blijft vlak onder het oppervlak een tunnel achter. Daarnaast kunnen lavatunnels ontstaan wanneer lava zich in bestaande breuken tussen gesteentelagen dwingt. De lava zet uit en creëert een heel netwerk van met elkaar in verbinding staande tunnels die – wanneer de erupties stilvallen – leeg komen te staan.
Tot op heden zijn er al meer dan 200 ‘putten’ ontdekt op het oppervlak van de maan. Deze putten zijn ontstaan door instortingen van onderliggende lavabuizen, wat leidt tot openingen naar ondergrondse holtes. Een prangende vraag is echter of deze putten toegang bieden tot grotten met uitgebreide ondergrondse ruimtes en of ze geschikt zijn om astronauten te huisvesten.
Mare Tranquillitatis Pit In een nieuwe studie hebben onderzoekers besloten om radargegevens van de Lunar Reconnaissance Orbiter te analyseren, specifiek gericht op de Mare Tranquillitatis Pit. Deze put staat bekend als de diepste op de maan, met een diameter van ongeveer 100 meter. “Wat we hebben gedaan, is radargegevens gebruiken om te onderzoeken of deze put een grot verborgen houdt,” vertellen onderzoekers Lorenzo Bruzzone en Leonardo Carrer in gesprek met Scientias.nl. “En wat we ontdekten, was dat de put in de Mare Tranquillitatis daadwerkelijk toegang geeft tot een grot, die we vervolgens in kaart hebben gebracht. Deze grot is bereikbaar vanaf het maanoppervlak. De meest waarschijnlijke verklaring voor onze waarnemingen is een lege lavabuis.”
Ze bestaan Het betekent dat Bruzzone en Carrer nu voor het eerst direct bewijs hebben gevonden van een toegankelijke lavatunnel onder het oppervlak. Een mijlpaal. “Al meer dan 50 jaar zijn maangrotten een mysterie,” vertelt Bruzzone. “Daarom was het opwindend om eindelijk het bestaan van een ondergrondse gang te kunnen bewijzen. Wat interessant is, is dat de gegevens die we in onze studie hebben gebruikt al veertien jaar beschikbaar zijn. Zoals in veel andere gevallen, heeft de ontwikkeling van nieuwe data-analysetechnologieën ook in ons geval geleid tot een nieuwe ontdekking door ‘oude’ gegevens opnieuw te analyseren.”
De maangrot De onderzoekers merkten een toename in radarhelderheid aan de westzijde van de Mare Tranquillitatis Pit op. Door simulaties uit te voeren op basis van de radarbeelden, hebben ze geconcludeerd dat deze observaties kunnen worden verklaard door de aanwezigheid van een holle ruimte die zich uitstrekt vanaf de westkant van de putbodem. De wetenschappers schatten dat deze holle ruimte zich bevindt op een diepte tussen 130 en 170 meter, met een lengte van 30 tot 80 meter en een breedte van ongeveer 45 meter. De grot is mogelijk ook vlak of heeft een helling van maximaal 45 graden.
Maankolonisten De ontdekking van de maangrot geeft hoop voor toekomstige maankolonisten. Zo toont het onderzoek aan dat ondergrondse grotten niet alleen bestaan, maar dat ze ook mogelijk bewoonbaar kunnen zijn. De Mare Tranquillitatis Pit en zijn ondergrondse holte worden bijvoorbeeld gezien als een veelbelovende locatie voor een toekomstige maanbasis. “Op dit moment lopen er verschillende internationale inspanningen van diverse ruimteagentschappen om te onderzoeken of dergelijke grotten geschikt kunnen zijn als schuilplaatsen,” zegt Carrer. “Als de omstandigheden gunstig blijken te zijn, bestaat de mogelijkheid dat ze in de toekomst als schuilplaatsen kunnen worden gebruikt.”
Uitdagingen Dat dit goed wordt onderzocht, is heel belangrijk. Dat komt omdat het leven ondergronds ook zo zijn eigen uitdagingen met zich meebrengt. “Bij het overwegen van het ondergronds huisvesten van astronauten op de maan is veiligheid de belangrijkste prioriteit,” onderstreept Carrer. “Elke mogelijke oplossing heeft zijn eigen voor- en nadelen op het gebied van veiligheid. Het grootste voordeel van grotten is dat ze de belangrijkste structurele onderdelen voor een mogelijke menselijke basis bieden, zonder dat er ingewikkelde bouwwerkzaamheden nodig zijn. Natuurlijk zijn er potentiële risico’s die grondig moeten worden overwogen en geanalyseerd. Denk bijvoorbeeld aan het uitvoeren van grondige structurele analyses om de stabiliteit van de grot te beoordelen, het versterken van de wanden en het plafond van de tunnels, het opzetten van alternatieve leefruimtes zodat astronauten kunnen verhuizen naar een andere veilige zone als een deel van de tunnel beschadigd raakt en het plaatsen van monitorsystemen die bijvoorbeeld aardbevingen kunnen registreren.”
Toekomstige missies De onderzoekers beschouwen hun studie als een startpunt voor verdere verkenning van maangrotten. Ze suggereren dat de gebruikte methode ook van nut kan zijn voor het onderzoeken van andere maanputten en het ontdekken van meerdere ondergrondse gangen. Al hebben we daar wel betere beelden van het maanoppervlak voor nodig. “Helaas zijn de huidige beschikbare gegevens zeer beperkt en bestrijken ze slechts een klein deel van het maanoppervlak,” merkt Bruzzone op. “Bovendien hebben ze niet genoeg detail om kleine grotten te kunnen waarnemen, die juist van groot belang zijn voor het plannen van een maanbasis. Daarom is het van cruciaal belang om nieuwe missies te plannen, bestaande uit satellieten die om de maan draaien en uitgerust zijn met radarinstrumenten. We hebben zowel een radar nodig zoals die we gebruikten voor onze recente ontdekking, om een gedetailleerde kaart te maken van alle maangrotten met voldoende resolutie, als een laagfrequente radarsonde die systematisch het maanoppervlak kan doordringen. Deze sonde moet specifiek ontworpen zijn om holtes en tunnels te detecteren, zelfs op locaties ver van de bekende putten.”
De studie markeert de eerste stap richting het begrijpen van maangrotten als potentiële verblijfplaatsen voor astronauten. Maar het is duidelijk dat er nog veel werk aan de winkel is voordat we kunnen bevestigen dat ze echt ideaal zijn voor langdurige bewoning. Toch zijn ruimtevaartorganisaties optimistisch gestemd. Sinds 2012 voert ESA bijvoorbeeld in samenwerking met enkele Europese universiteiten twee trainingsprogramma’s uit voor astronauten die gericht zijn op de ondergrondse systemen van Lanzarote. Tot dusver hebben al tientallen astronauten trainingen in ‘grotwandelen’ gekregen. Daarnaast hebben al enkele astronauten een geologische veldtraining gevolgd. Dit toont aan dat ESA de lavatunnels op andere hemellichamen zeer geschikt acht als verblijfplaatsen. En wellicht zullen deze ondergrondse systemen inderdaad de eerste nieuwe woonomgevingen voor mensen op een ander hemellichaam worden.
ORLANDO, Fla. — NASA and Boeing completed tests on the ground looking to mirror conditions that led to problems with the CST-100 Starliner that still awaits the go to bring home a pair of astronauts from the International Space Station.

Butch Wilmore and Suni Williams docked Starliner at the ISS back on June 6 on the Crew Flight Test mission one day after launching from Cape Canaveral Space Force Station atop a United Launch Alliance Atlas V rocket.
What was originally planned to be just an eight-day stay on board the ISS has stretched to more than six weeks because of issues with helium leaks and thruster shutdowns on Starliner’s propulsion module as it approached the station.
While NASA has signed off on Starliner as safe enough to get its two NASA astronauts home in case of an emergency, it’s taking its time to look into as much data as possible about the thrusters and helium leaks before giving them the green light to come home and complete the CFT mission.
After docking, the helium lines were shut down, so no more leaking has occurred, but it will begin again once it undocks. NASA has said the spacecraft, though, has ample helium supply to make the trip home. As far as the reaction control thrusters, which are needed for small position corrections, NASA was able to get four of the five that failed on approach back online, although at lower power levels.

It’s a similar issue seen on the previous Starliner flight, the uncrewed Orbital Flight Test 2 in 2022.
A big issue is the problem propulsion hardware, housed on what’s called the service module, won’t make the flight home along with the crew capsule as it is jettisoned before reentry.
So teams took a surrogate engine for hot fire testing at NASA’s White Sands Test Facility in New Mexico, which was completed last week, mirroring both conditions Starliner experienced on the flight up as well as conditions expected for the return home.
Now teams will evaluate all the test firing data and inspect the engine with work expected to last through this week.
“I am extremely proud of the NASA, Boeing team for their hard work in executing a very complex test series,” said Steve Stich, manager, NASA’s Commercial Crew Program in a press release. “We collected an incredible amount of data on the thruster that could help us better understand what is going on in flight. Next, our team has moved into engine tear downs and inspections which will provide additional insight as we analyze the results and evaluate next steps.”
Before NASA will let Starliner undock, Stich said it has to go through an agency flight test readiness review, and that date has yet to be identified.
Stich previously said that return flight could occur before the end of July, but could also remain on station into mid-August with only the launch of the replacement Crew-9 on a SpaceX Crew Dragon looming next month that would cause a traffic jam.
The CFT mission aims to be the last step before NASA signs off on Boeing to begin the first of six contracted flights to ferry crew to and from the ISS before the station’s retirement as part of NASA’s Commercial Crew Program.
SpaceX is more than four years ahead of Boeing’s efforts as part of the program, and is in the midst of its eighth operational mission to the ISS.
NASA's Curiosity rover discovers a surprise in a Martian rock
NASA's Curiosity rover discovers a surprise in a Martian rock
Story by Science X staff
These yellow crystals were revealed after NASA's Curiosity happened to drive over a rock and crack it open on May 30. Using an instrument on the rover's arm, scientists later determined these crystals are elemental sulfur—and it's the first time this kind of sulfur has been found on the Red Planet.
Scientists were stunned on May 30 when a rock that NASA's Curiosity Mars rover drove over cracked open to reveal something never seen before on the Red Planet: yellow sulfur crystals.
Since October 2023, the rover has been exploring a region of Mars rich with sulfates, a kind of salt that contains sulfur and forms as water evaporates. But where past detections have been of sulfur-based minerals—in other words, a mix of sulfur and other materials—the rock Curiosity recently cracked open is made of elemental (pure) sulfur. It isn't clear what relationship, if any, the elemental sulfur has to other sulfur-based minerals in the area.
While people associate sulfur with the odor from rotten eggs (the result of hydrogen sulfide gas), elemental sulfur is odorless. It forms in only a narrow range of conditions that scientists haven't associated with the history of this location. And Curiosity found a lot of it—an entire field of bright rocks that look similar to the one the rover crushed.
"Finding a field of stones made of pure sulfur is like finding an oasis in the desert," said Curiosity's project scientist, Ashwin Vasavada of NASA's Jet Propulsion Laboratory in Southern California. "It shouldn't be there, so now we have to explain it. Discovering strange and unexpected things is what makes planetary exploration so exciting."
It's one of several discoveries Curiosity has made while off-roading within Gediz Vallis channel, a groove that winds down part of the 3-mile-tall (5-kilometer-tall) Mount Sharp, the base of which the rover has been ascending since 2014. Each layer of the mountain represents a different period of Martian history. Curiosity's mission is to study where and when the planet's ancient terrain could have provided the nutrients needed for microbial life, if any ever formed on Mars.
NASA’s Curiosity captured this close-up image of a rock nicknamed “Snow Lake” on June 8, 2024, the 4,209th Martian day, or sol, of the mission. Nine days earlier, the rover had crushed a similar-looking rock and revealed crystalline textures—and elemental sulfur—inside.
NASA/JPL-Caltech/MSSS NASA’s Curiosity Mars rover captured this view of Gediz Vallis channel on March 31. This area was likely formed by large floods of water and debris that piled jumbles of rocks into mounds within the channel.
Spotted from space years before Curiosity's launch, Gediz Vallis channel is one of the primary reasons the science team wanted to visit this part of Mars. Scientists think that the channel was carved by flows of liquid water and debris that left a ridge of boulders and sediment extending 2 miles down the mountainside below the channel. The goal has been to develop a better understanding of how this landscape changed billions of years ago, and while recent clues have helped, there's still much to learn from the dramatic landscape.
Since Curiosity's arrival at the channel earlier this year, scientists have studied whether ancient floodwaters or landslides built up the large mounds of debris that rise up from the channel's floor here. The latest clues from Curiosity suggest both played a role: Some piles were likely left by violent flows of water and debris, while others appear to be the result of more local landslides.

Those conclusions are based on rocks found in the debris mounds: Whereas stones carried by water flows become rounded like river rocks, some of the debris mounds are riddled with more angular rocks that may have been deposited by dry avalanches.
Finally, water soaked into all the material that settled here. Chemical reactions caused by the water bleached white "halo" shapes into some of the rocks. Erosion from wind and sand has revealed these halo shapes over time.
"This was not a quiet period on Mars," said Becky Williams, a scientist with the Planetary Science Institute in Tucson, Arizona, and the deputy principal investigator of Curiosity's Mast Camera, or Mastcam. "There was an exciting amount of activity here. We're looking at multiple flows down the channel, including energetic floods and boulder-rich flows."
A hole in 41
All this evidence of water continues to tell a more complex story than the team's early expectations, and they've been eager to take a rock sample from the channel in order to learn more. On June 18, they got their chance.
While the sulfur rocks were too small and brittle to be sampled with the drill, a large rock nicknamed "Mammoth Lakes" was spotted nearby. Rover engineers had to search for a part of the rock that would allow safe drilling and find a parking spot on the loose, sloping surface.
After Curiosity bored its 41st hole using the powerful drill at the end of the rover's 7-foot (2-meter) robotic arm, the six-wheeled scientist trickled the powderized rock into instruments inside its belly for further analysis so that scientists can determine what materials the rock is made of.
Curiosity has since driven away from Mammoth Lakes and is now off to see what other surprises are waiting to be discovered within the channel.

UFO expert worried 'alien craft followed me home' after shooting film on ETs
UFO expert worried 'alien craft followed me home' after shooting film on ETs
EXCLUSIVE: We're all often told not to take our work home with us, but for one avid UFO expert this was seemingly made hard to do after he returned from a shoot to find a UFO loitering near his house
What do you make of it? Let us know in the comments

A UFO investigator has spotted a strange orb he thinks might have followed him home after visiting “The British Roswell”.
Mark Christopher Lee had been in Suffolk making a film in Rendelsham, Suffolk about a 1980 UFO incident that was reported there. But when he got home, he had the strange feeling that something might have followed him home from the shoot.
He felt it weird that, after being away working purely on unidentified phenomena, he returned home to more of the same. “I just question whether we brought something back with us from Rendelsham Forest? Or was it something else?” Mark said.
He told the Daily Star: “It was definitely weird – at first I thought it was an aircraft, but it wasn’t, there was light reflecting off it. There are planes nearby, we get a lot of planes because we live near Luton Airport.
The object 'blipped' in and out(Image: Youtube/NubTV)
“It wasn’t moving, planes come towards you or go away, it was just kind of swaying side to side a little bit. It wasn’t a balloon, there was a bit of a breeze so it would have had more movement. It seemed to be blipping in and out.
“Bear in mind it was a beautiful blue sky and no clouds in the sky. Where was it blipping to? It kept coming back it was very weird.
Mark Christopher Lee spoke to the Daily Star
“It’s definitely unexplained. It was too low for a satellite. I’m quite rational so I try and rule things out but I was left speechless. The fact that it was in the daytime as well.
“I just wonder if there was anyone else in the area that saw it.”
Scottish region branded 'UK's Bermuda Triangle' after 100s of UFO sightings

A tiny village sandwiched in between Glasgow and Edinburgh has been labelled the UFO hotspot of the UK thanks to hundreds of sightings reported by locals every year

A small village in Scotland is at the centre of a UFO hotspot region compared to the Bermuda Triangle.
With a population little over 5,000, the village that is placed directly in between Glasgow and Edinburgh was once a beacon for industry. But it is now known for something very different.
Often branded as the UK's answer to Roswell, there have been an average of 300 UFO sightings across the region every year. The reported spacecrafts supposedly take on all different shapes and sizes including cigar shaped crafts over head and even some instances of alien abductions.
Such is the mystery around the strange phenomena that the area has even been coined the 'Falkirk Triangle'.
Many have mused down the years whether the village could be a passage into another dimension, much like the Bermuda Triangle is reported to be. Others have also proposed that the Forth and Clyde Canal acts as a Bermuda-eque stream in between dimension.
Councillor for Falkirk, William Buchanan spoke about one of the more peculiar alien sightings reported in the area(Image: Getty Images/Science Photo Library RF)
And, in a documentary made by TalkTV one encounter stands out ahead of the rest as Councillor for Falkirk, William Buchanan recalls: "I was in the house one night, and I'd just come back from the council, and what happened is, I'd seen a car coming into the driveway and I went out to find out who it was. It was a chap I've known all my days and he say's 'is it okay, can we talk?'.
He continues: "He said 'I need to talk to somebody'. This individual was having an assignation, they were making love, but the problem was that this was his brother's wife, so that in itself was a situation."
But, what Buchanan would describe next is even more shocking, he added: "The next thing is, coming into the woods there, up came these 6ft black aliens looking in the windows and then the next thing is he was in a spaceship and he was getting prodded. He says since that happened we've had ESP (Extra Sensory Perception). He says 'I can levitate. I'e got all these strange powers'.
Despite all of the mysterious goings on across the region, some have put forward other explanations for the disproportionate amount of UFO sightings.
One is that they can simply be put down to top secret military testing, a theory that is often suggested in areas with high levels of UFO reports. Some have even suggested that Bonnybridge would provide the perfect spot for such testing due to its landscape.
Another explanation could be that the UFO-like 'beams of light' could be a result of a natural event such as an aurora or balls of gas that as spectacular as they are, they certainly have nothing to do with extraterrestrials.
Study: Biological Amino Acids Could Survive in Near-Surface Ices of Europa and Enceladus
Study: Biological Amino Acids Could Survive in Near-Surface Ices of Europa and Enceladus
Europa and Enceladus are key targets to search for evidence of alien life in our Solar System. However, the surface and shallow subsurface of these airless icy moons are constantly bombarded by ionizing radiation that could degrade chemical biosignatures. Therefore, sampling of icy surfaces in future life detection missions to Europa and Enceladus requires a clear understanding of the necessary ice depth where unaltered organic biomolecules might be present. A team of scientists from NASA and the Pennsylvania State University has conducted experiments by exposing individual biological and abiotic amino acids in ices to gamma radiation to simulate conditions on these icy worlds.
The surface of Europa looms large in this newly-reprocessed color view; image scale is 1.6 km per pixel; north on Europa is at right.

“Based on our experiments, the ‘safe’ sampling depth for amino acids on Europa is almost 20 cm (8 inches) at high latitudes of the trailing hemisphere (hemisphere opposite to the direction of Europa’s motion around Jupiter) in the area where the surface hasn’t been disturbed much by meteorite impacts,” said Dr. Alexander Pavlov, a researcher at NASA’s Goddard Space Flight Center.
“Subsurface sampling is not required for the detection of amino acids on Enceladus — these molecules will survive radiolysis (breakdown by radiation) at any location on the Enceladus surface less than a few millimeters (a tenth of an inch) from the surface.”
Dr. Pavlov and his colleagues used amino acids in radiolysis experiments as possible representatives of biomolecules on icy moons.
Amino acids can be created by life or by non-biological chemistry.
However, finding certain kinds of amino acids on Europa or Enceladus would be a potential sign of life because they are used by terrestrial life as a component to build proteins.
Proteins are essential to life as they are used to make enzymes which speed up or regulate chemical reactions and to make structures.
Amino acids and other compounds from subsurface oceans could be brought to the surface by geyser activity or the slow churning motion of the ice crust.
To evaluate the survival of amino acids on these worlds, the researchers mixed samples of amino acids with ice chilled to about minus 196 Celsius (minus 321 Fahrenheit) in sealed, airless vials and bombarded them with gamma-rays, a type of high-energy light, at various doses.
Since the oceans might host microscopic life, they also tested the survival of amino acids in dead bacteria in ice.
Finally, they tested samples of amino acids in ice mixed with silicate dust to consider the potential mixing of material from meteorites or the interior with surface ice.
The experiments provided pivotal data to determine the rates at which amino acids break down, called radiolysis constants.
With these, the scientists used the age of the ice surface and the radiation environment at Europa and Enceladus to calculate the drilling depth and locations where 10% of the amino acids would survive radiolytic destruction.
Although experiments to test the survival of amino acids in ice have been done before, this is the first to use lower radiation doses that don’t completely break apart the amino acids, since just altering or degrading them is enough to make it impossible to determine if they are potential signs of life.
This is also the first experiment using Europa/Enceladus conditions to evaluate the survival of these compounds in microorganisms and the first to test the survival of amino acids mixed with dust.
The scientists found that amino acids degraded faster when mixed with dust but slower when coming from microorganisms.
“Slow rates of amino acid destruction in biological samples under Europa and Enceladus-like surface conditions bolster the case for future life-detection measurements by Europa and Enceladus lander missions,” Dr. Pavlov said.
“Our results indicate that the rates of potential organic biomolecules’ degradation in silica-rich regions on both Europa and Enceladus are higher than in pure ice and, thus, possible future missions to Europa and Enceladus should be cautious in sampling silica-rich locations on both icy moons.”
“A potential explanation for why amino acids survived longer in bacteria involves the ways ionizing radiation changes molecules — directly by breaking their chemical bonds or indirectly by creating reactive compounds nearby which then alter or break down the molecule of interest.”
“It’s possible that bacterial cellular material protected amino acids from the reactive compounds produced by the radiation.”
The team’s paper was published in the journal Astrobiology.

Dat de aarde steeds langzamer draait is geen mysterie, tenminste niet binnen de wetenschappelijke gemeenschap. De redenen hiervoor zijn divers en hebben te maken met de natuurlijke processen die onze planeet beïnvloeden... voor het grootste deel. Volgens recent wetenschappelijk onderzoek vertraagt de rotatiesnelheid van de aarde echter door toedoen van de mens en zijn activiteiten. Laten we eens kijken hoe dit mogelijk is en wat de gevolgen zijn voor onze samenleving.
Van de maan tot de gletsjers: een reis op een steeds trager wordende planeet
Zoals we in de inleiding zeiden, is het onderhand bekend dat de rotatiesnelheid van de aarde om haar as noch vast, noch constant is, voornamelijk als gevolg van twee verschillende processen:
aan de ene kant vertraagt de kern van de Aarde haar rotatiesnelheid;
aan de andere kant verwijdert de Maan zich steeds verder van de Aarde.
Dit zijn natuurlijke processen die leiden tot werkelijk oneindige veranderingen in de rotatiesnelheid van onze planeet, en dus ook in de lengte van de dagen. Door de verwijdering van de maan zal de dag van de aarde bijvoorbeeld 25 uur duren, maar over 200 miljoen jaar. Toch spreekt onderzoek uitgevoerd door het centrum ETH Zürich in samenwerking met NASA over een andere factor die de rotatiesnelheid van de aarde zou kunnen vertragen: de stijging van de temperatuur als gevolg van menselijke activiteiten.
Het verband lijkt werkelijk paradoxaal, maar het is er wel. Onderzoekers hebben namelijk ontdekt hoe hogere temperaturen een kettingreactie hebben veroorzaakt die de dagen op aarde feitelijk verlengt. Het smelten van gletsjers op Antarctica en Groenland leidt er feitelijk toe dat miljoenen kubieke meters water over het hele aardoppervlak worden verspreid, waardoor de rotatiesnelheid van de planeet effectief wordt vertraagd.
De gevolgen van de vertraging van de aarde… op aarde

In hun eerste onderzoek, gepubliceerd in het tijdschrift PNAS, merken de onderzoekers op hoe de temperatuurstijging om antropogene redenen leidt tot langere dagen. Hetzelfde team publiceerde echter ook een tweede onderzoek in het tijdschrift GeoScience, waarin ze kijken naar hoe smeltende gletsjers bijdragen aan het veranderen van de positie van de rotatie-as van de aarde. Samen met andere verschijnselen, zoals de eerder genoemde bewegingen van de kern van de aarde, verschuift de rotatie-as elke 100 jaar ongeveer 10 meter.
De effecten die kunnen worden toegeschreven aan smeltende gletsjers en menselijke activiteiten zijn minimaal, maar er is geen reden tot vreugde. Alle verschijnselen die door de onderzoekers zijn geanalyseerd, zijn namelijk terug te voeren op natuurlijke verschijnselen, en dat hebben we gezien: de maan die afstand neemt, het effect van de getijden, de binnenkern en haar bewegingen, enzovoort. In zo'n beeld speelt echter ook de hand van de mens een rol en kan leiden tot plotselinge versnellingen van deze processen.
De gevolgen van de vertraging van de aarde... voor de mens
De interne en externe processen op aarde zijn daarom meer met elkaar verbonden dan we denken: zoals we hebben gezien, kunnen ze elkaar beïnvloeden, maar ook de menselijke activiteiten die bijdragen aan het veroorzaken ervan. Hoewel de vertraging van de rotatiesnelheid van de aarde momenteel minimaal is en de dagen slechts fracties van een seconde langer worden, zijn de gevolgen voor de mens al aanzienlijk.
De tijdmeting van de mens is gebaseerd op uiterst nauwkeurige atoomklokken. Deze precisie wordt echter in gevaar gebracht door de interactie tussen de verschillende factoren die bijdragen aan het verlengen van de dagen op aarde. Het risico is dat we minder nauwkeurige GPS hebben, met alle gevolgen van dien voor alle menselijke activiteiten.
Aan de andere kant: als de vertraging tot 2000 tussen de 0,3 en 1 milliseconde per eeuw lag, zitten we nu op ongeveer 1,3 milliseconden per eeuw, maar dit lijkt voorbestemd om te stijgen. Het is een neerwaartse spiraal waar we de afgelopen decennia steeds meer vertrouwd mee zijn geworden... en die we nog kunnen vertragen als we tijdig handelen.
Amazon UFO Secrets: Researcher Uncovers Mysterious Sounds in the Rainforest
Amazon UFO Secrets: Researcher Uncovers Mysterious Sounds in the Rainforest
The Amazon rainforest, a place often associated with vast biodiversity and hidden natural wonders, has recently become the focus of UFO research. Brazilian UFO researcher Rony Vernet has uncovered extraordinary phenomena that suggest the presence of unidentified aerial phenomena (UAP) deep within this dense jungle.
In a recent episode of “Reality Check with Ross Coulthart,” Vernet shared his findings after an expedition to the Amazon rainforest, specifically a remote area near the border of Brazil and Peru. Vernet’s journey was inspired by a long history of unexplained UAP incidents in the region, dating back to at least the mid-1970s.
Background on UAP Activity in the Amazon
The Amazon and its surrounding areas have been hotspots for UAP sightings for decades. In 1977, a series of UAP incidents in the Brazilian states of Pará and Maranhão drew significant attention. Hundreds of people reported being struck by light beams emitted from UAPs, particularly around the city of Colares. These incidents led to Operation Saucer (Operação Prato), an investigation by the Brazilian Air Force, which officially found no unusual phenomena. However, locals reported injuries consistent with microwave burns, and some even claimed that individuals were killed by these light beams.
In more recent years, there have been continued reports of UAP activity. In 2013, unidentified aerial phenomena were observed over a village in Acre, Brazil, near the Peruvian border. By 2014, these sightings escalated to UAPs descending into the village and emitting light beams at the indigenous people, prompting an investigation by the National Indigenous Foundation and federal authorities.
Vernet’s Expedition and Findings
Driven by these historical reports, Vernet embarked on an expedition to the Yanawa Indigenous Tribe in Acre province. His goal was to gather firsthand evidence of these phenomena. Over the course of his investigation, Vernet experienced a series of inexplicable events, beginning with what he described as poltergeist-like activity.
On his first night in the jungle, Vernet reported hearing loud, metallic sounds that had no apparent source. These sounds resembled furniture being dragged across a wooden floor, yet there were no structures nearby that could produce such noises. Despite thorough searches, Vernet and his team could not find any logical explanations for these occurrences.
The following night, Vernet explored an abandoned house in the jungle, which was filled with objects as if its inhabitants had left suddenly. Here, he and his team felt an overwhelming sense of fear and coldness, unlike anything they had experienced before. The eerie environment only added to the mystery of the phenomena they were investigating.
Encounters with Luminous Spheres
As Vernet continued his investigation, he began to observe luminous phenomena. Indigenous people frequently reported seeing orange or yellow spheres, described as golden balls of fire, hovering near their homes. These spheres often appeared on the rooftops, seemingly observing the inhabitants. Remarkably, whenever someone attempted to point at or directly engage with the spheres, they would disappear instantly.
On one occasion, while setting up monitoring equipment, Vernet and his team witnessed a large, red-orange sphere less than a meter from the ground and only about five meters away from them. Despite its brightness, the sphere made no noise and could be stared at without discomfort. When Vernet attempted to capture the phenomenon with a drone, the sphere evaded recording by somehow remaining invisible to the drone’s camera despite being clearly visible to the naked eye.
Technological and Sensor Data
Vernet’s research was not limited to visual observations. He brought a variety of sophisticated equipment, including thermal cameras, cosmic ray sensors, infrasound detectors, and microwave antennas, to gather as much data as possible. Notably, during these encounters, he detected a 1.6 GHz signal, a frequency also observed during similar phenomena at Skinwalker Ranch in the United States.
Although some of his sensors were not fully operational during the initial nights, Vernet plans to analyze the collected data to find correlations between the visual phenomena and the sensor readings. His initial findings suggest that the UAPs might have the capability to interfere with electronic devices, as witnessed when camera equipment and flashlights malfunctioned during sightings.
Indigenous Perspectives and Scientific Interpretation
The indigenous communities in the Amazon have their own interpretations of these phenomena, often linking them to spiritual beliefs. The Yanawa tribe, for instance, regards certain areas of the forest as portals where beings from the spirit world traverse into our reality. Vernet’s research, combining modern scientific methods with indigenous knowledge, aims to provide a comprehensive understanding of these mysterious occurrences.
Conclusion
Rony Vernet’s investigation into the Amazon’s UAP phenomena has provided compelling evidence that these mysterious lights and sounds are more than mere folklore. His findings suggest a highly intelligent phenomenon capable of interacting with and evading human observation. As Vernet continues to analyze the data and collaborate with other scientists, his work could bring us closer to understanding the enigmatic UAPs of the Amazon rainforest.
The combination of scientific inquiry and indigenous wisdom in Vernet’s approach sets a new precedent for UAP research. By respecting and incorporating the knowledge of local communities, researchers like Vernet are paving the way for a more holistic understanding of these phenomena, which could one day unravel the secrets of the Amazon’s skies.
Wetenschappers van een laboratorium in het Franse Marseille hebben gewaarschuwd voor de mogelijkheid van een nieuwe pandemie in de toekomst. Deze zou immers kunnen worden veroorzaakt door een virus dat al meer dan 30.000 jaar bevroren is.
Microben in het noordpoolgebied zouden de oorzaak kunnen zijn, nadat de opwarming van de aarde, de toegenomen menselijke activiteit en de aanwezigheid van schepen in de regio het ontdooi- en smeltproces versnellen.
Volgens de onderzoekers is de kans groot dat deze en andere virussen, als het ontdooiproces doorgaat, zich vrij zullen verspreiden en uiteindelijk nieuwe ziekten veroorzaken.
Dit ‘zombievirus’ werd door laboratoriumonderzoekers ontdekt in een laag Siberische permafrost die duizenden jaren bevroren was in het noordwesten van Siberië.
Het nieuws werd in The Guardian becommentarieerd door de Nederlandse viroloog Marion Koopmans, die beweerde dat “we niet weten welk virus zich in de permafrost bevindt. Maar ik denk dat er een reëel risico bestaat dat er één virus is dat een epidemie kan veroorzaken, bijvoorbeeld een oude vorm van polio. We moeten aannemen dat zoiets zou kunnen gebeuren”, waarschuwde ze.

Swarming Satellites Could Autonomous Characterize an Asteroid
An asteroid’s size, shape, and rotational speed are clues to its internal properties and potential resources for mining operations. However, of the more than 20,000 near-Earth asteroids currently known, only a tiny fraction have been sufficiently characterized to estimate those three properties accurately. That is essentially a resource constraint – there aren’t enough dedicated telescopes on Earth to keep track of all the asteroids for long enough to characterize them, and deep space resources, such as the Deep Space Network required for communications outside Earth’s orbit, are already overutilized by other missions. Enter the Autonomous Nanosatellite Swarming (ANS) mission concept, developed by Dr. Simone D’Amico and his colleagues at Stanford’s Space Rendezvous Laboratory.
The concept behind ANS is relatively simple. A primary “mothership” spacecraft travels to an asteroid, where it deploys several smaller, autonomous nanosatellites upon arrival. These nanosatellites take up positions surrounding the asteroid and, using relatively inexpensive sensor and communications technology, map the asteroid’s features. After observing for some time, they send data back to the mothership, where an algorithm pieces together information similar to a stereo vision system on Earth and calculates the asteroid’s shape, size, and rotational speed.
There are several deeper layers to unpack in the mission, though. Communication is the first one. In ANS, only the mothership communicates back to Earth using a high-gain antenna. The smaller swarming robots all communicate with each other – partly to estimate distances between the different swarming satellites but also to coordinate observations.
Characterization is the first step toward exploitation, as Fraser discusses.
Each nanosatellite utilizes only a few relatively inexpensive pieces of hardware, including a star tracker for overall positioning, short range camera (as compared to more expensive lidar systems typically used in asteroid characterization missions), atomic clocks to synchronize timing, and radio frequency communication modules. These components allow for relatively independent operation of each nanosatellite and lower the burden of communication back with Earth – freeing up those deep space communications resources for other critical work.
But the critical component of ANS isn’t so much the hardware—it’s the software, particularly the control and estimation algorithm. Dr. D’Amico and his team describe a technical tool known as an unscented Kalman filter, which allows them to estimate asteroid shape, size, and rotation based on landmarks noticed by each swarming nanosatellite and run through this algorithm.
To demonstrate the effectiveness of that algorithm, the team tested it using a relatively well-characterized asteroid: 443 Eros. That asteroid had the distinction of being both the first near-Earth object ever found, back in 1898, and the first ever visited by a mission – the NEAR mission 100 years later. The NEAR Shoemaker craft that visited 433 Eros also successfully landed on it, another first for humanity. Even with the comparatively simple sensing technology of a quarter century ago, Eros is still one of the most characterized asteroids in the solar system.
Here’s a talk about autonomous swarming given by Dr. D’Amico, the head of Stanford’s Space Rendezvous Lab.
The demonstration results clearly showed that the ANS algorithm does its job well. It can coordinate the positioning of the nanosatellites surrounding the asteroid and coalesce their disparate data sets into a coherent picture of the asteroid they are monitoring. And it can do so remotely, with very minimal input from Earth.
For now, that is how far the algorithm has gotten. Several missions, some of which we’ll cover in the near future, further explore the idea of nanosatellite swarms. But ANS itself hasn’t yet been adopted into a formal mission architecture. One day, though, thousands of satellites might be swarming the tens of thousands of small bodies surrounding our home, leading to the first stages of a genuinely off-Earth economy.
The Most Dangerous Part of a Space Mission is Fire

The Most Dangerous Part of a Space Mission is Fire
Astronauts face multiple risks during space flight, such as microgravity and radiation exposure. Microgravity can decrease bone density, and radiation exposure is a carcinogen. However, those are chronic effects.
The biggest risk to astronauts is fire since escape would be difficult on a long mission to Mars or elsewhere beyond Low Earth Orbit. Scientists are researching how fire behaves on spacecraft so astronauts can be protected.
“A fire on board a spacecraft is one of the most dangerous scenarios in space missions,” said Dr. Florian Meyer, head of the Combustion Technology research group at ZARM. “There are hardly any options for getting to a safe place or escaping from a spacecraft. It is therefore crucial to understand the behavior of fires under these special conditions.”
Since 2016, ZARM has been researching how fire behaves and spreads in microgravity conditions like those in the ISS. Those conditions also include an oxygen level similar to Earth’s, forced air circulation, and ambient pressure similar to Earth’s. NASA has been conducting similar experiments, and now we know that fire behaves differently in microgravity than it does on Earth.
Initially, a fire will burn with a smaller flame and take longer to spread. This is to the fire’s advantage since it won’t be noticed as quickly. Fire also burns hotter in microgravity, meaning that some materials that may not be combustible in normal Earth conditions could burn in spacecraft, creating toxic chemicals in the spacecraft’s air.
Spacecraft for Mars missions will have different environments than the ISS. The ambient air pressure will be lower, which provides two benefits: it makes the spacecraft lighter and also allows astronauts to prepare for external missions more quickly. However, the lower ambient pressure introduces another critical change in the spaceship environment. The oxygen content has to be higher to meet the astronauts’ respiration needs.
In these latest tests, the team at ZARM tested fire in these revised conditions.
PMMA stands for polymethyl methacrylate and is usually called acrylic. It’s a common material used in place of glass because it’s light and shatterproof. The ISS doesn’t use it, but it’s being developed for use in future spacecraft. The Orion capsule uses acrylic fused to other materials for windows, and future spacecraft will likely use something similar.
In their experiments, the researchers lit acrylic glass foils on fire and varied three environmental factors: ambient pressure, oxygen content and flow velocity.

The experiments showed that lower ambient pressure dampens fire. However, higher oxygen content has a more powerful effect. The ISS’s oxygen level is 21%, just as it is on Earth. Future spacecraft with lower ambient pressures will have oxygen levels as high as 35%. That translates into a huge increase in the risk astronauts face from fire. The results show that a fire can spread three times faster than it would under Earth conditions.
“Our results highlight critical factors that need to be considered when developing fire safety protocols for astronautic space missions.”

We all know increased airflow spreads fire faster; that’s why we blow on a small flame to create a larger fire. Increased airflow delivers more oxygen, increasing combustion, so increased airflow in a higher-oxygen atmosphere creates a dangerous situation for astronauts.
“Our results highlight critical factors that need to be considered when developing fire safety protocols for astronautic space missions,” said Dr. Florian Meyer. “By understanding how flames spread under different atmospheric conditions, we can mitigate the risk of fire and improve the safety of the crew.”
Meteor Exploded Over N.Y.C. at 38,000 MPH: 'Rare Daylight Fireball'
Meteor Exploded Over N.Y.C. at 38,000 MPH: 'Rare Daylight Fireball'
Story by Anna Lazarus Caplan
NASA said that it does not track small meteors at "significant" distances from Earth, but individuals in New York and New Jersey reported witnessing the event
A small meteor was responsible for a big fireball over New York City on Tuesday, July 16, authorities said.
The astronomical event was first detected about 49 miles above Upper Bay/New York Harbor and moved west towards New Jersey at 38,000 mph, passing over the Statue of Liberty before disintegrating about 29 miles above midtown Manhattan, NASA confirmed in a statement.
Witnesses described seeing a fireball, hearing “booms” and feeling “shakings” between 10 a.m. to 12 p.m. local time, NASA said.
It is unclear if the sounds were related to the meteor or were due to military operations happening at the same time in New Jersey, Bill Cooke, with NASA’s Meteoroid Environments Office said, per ABC affiliate WABC-TV.
However, he added that the event was an unusual occurrence.
"Something when it's moving that fast it heats up,” Cooke said. “You expect to see meteors at night not during the day, so this was a rare daylight fireball."
While no meteorites were reported, the meteor gave pause to those underneath its trajectory.

"It was long and really, really fast," Judah Bergman, who saw the meteor from his Lakewood, N.J. office, told WABC. "It looked like a flaming, long rod or something on fire and flying through the sky."
The meteor was not even on NASA’s radar, at first, according to the organization.
“We do keep track of asteroids that are capable of posing a danger to us Earth dwellers, but small rocks like the one producing this fireball are only about a foot in diameter, incapable of surviving all the way to the ground,” NASA said in its statement. “We do not (actually cannot) track things this small at significant distances from the Earth, so the only time we know about them is when they hit the atmosphere and generate a meteor or a fireball.”
While some seasoned New Yorkers were nonplussed, according to The New York Times, at least one resident who observed the moment reveled in its rarity.
“There’s something magical about it,” Tina Dang, a private chef, said. “You forget about these incredible moments in life, when so much else is going on.”
IJssmelt aangespoord door door de mens veroorzaakte opwarming van de aarde wijzigt de massaverdeling van onze planeet, vertraagt uiteindelijk de rotatie van de aarde en verlengt de 24-uursdag, volgens een studie gepubliceerd op 15 juli in het tijdschrift Proceedings van de National Academy of Sciences. Eerder onderzoek heeft vergelijkbare bevindingen gedaan, maar de nieuwe studie suggereert dat klimaatverandering een grotere impact heeft op de daglengte dan eerder werd gedacht.
Als het gebruik van fossiele brandstoffen en de uitstoot van broeikasgassen blijven toenemen in een algemeen genoemd scenario met hoge opwarming, bekend als RCP 8.5, dan zou klimaatverandering een grotere invloed kunnen hebben op de rotatie en daglengte van de aarde dan de maan, volgens de nieuwe bevindingen.
Veel factoren hebben een klein maar significant effect op de daglengte, waaronder de beweging van magma in de vloeibare kern van de aarde, windfluctuaties en de stroming van water op het oppervlak van onze planeet. Zoals het is, creëert de maan getijden die heen en weer wrijving produceren die de rotatie van onze planeet vertraagt. Op de schaal van de geologische tijd heeft dit maaneffect de grootste bijdrage geleverd aan veranderingen in de daglengte in de geschiedenis van onze planeet. Toch is de door de mens veroorzaakte opwarming van de aarde bezig met een inhaalslag.
De aarde is geen perfecte bol, het is "afgeplat", wat betekent dat het licht samengedrukt is langs de evenaar in een subtiele 3D-ovale vorm. Naarmate de ijskappen van Groenland en Antarctica smelten, beweegt er meer water en massa van de polen naar de evenaar. Dit maakt de aarde effectief verder plat, waardoor het midden nog breder en zwaarder wordt dan de boven- en onderkant, waardoor de rotatie enigszins wordt vertraagd als gevolg van de toegenomen traagheid. "Het is net als wanneer een kunstschaatsster een pirouette maakt, waarbij ze eerst haar armen dicht bij haar lichaam houdt en ze vervolgens uitstrekt", zei senior onderzoeker Benedikt Soja, hoogleraar ruimtegeodesie aan de ETH Zürich in Zwitserland, in een persverklaring. Met uitgestrekte armen zou de kunstschaatser vertragen, en twee eeuwen aan observatiegegevens en modellen suggereren dat onze planeet dat ook is.
Onderzoekers berekenden het smelten van ijs en de bijbehorende veranderingen in de afgeplatheid van de aarde met behulp van observatiegegevens die sinds 1976 zijn verzameld en modelleerden reconstructies en projecties van 1900 tot 2100. In de 20e eeuw ontdekten ze dat klimaatverandering de dag tussen 0,3 en 1,0 milliseconden verlengde. Sinds 2000 is de snelheid van door klimaatverandering veroorzaakte dagverlenging echter versneld tot ongeveer 1,33 milliseconden per eeuw. In het RCP 8.5-scenario met hoge emissies voorspellen de wetenschappers dat de snelheid van dagverlenging zou verdubbelen tot ongeveer 2.62 milliseconden per eeuw, waarmee officieel de getijdenwrijving van de maan zou worden overtroffen als de belangrijkste langetermijnkracht die op de daglengte van de aarde inwerkt.
Een paar milliseconden per eeuw klinkt misschien als kruimels in vergelijking met de universele taart, maar het kan oplopen tot dagen die uren langer zijn gedurende miljarden jaren. Op de kortere termijn hebben de door het klimaat veroorzaakte verschuivingen invloed op nauwkeurige tijdregistratie, die wordt gebruikt om nauwkeurige en soepele GPS-navigatie, wereldwijde communicatie, elektriciteitsnetten en financiële systemen te behouden. Ook de verkenning van de ruimte kan door de verandering worden beïnvloed, omdat zelfs kleine afwijkingen in rotatie en positie op aarde kunnen leiden tot grote misrekeningen als het gaat om het navigeren en corrigeren van het landen van een sonde over grote afstanden elders in het zonnestelsel.
Een verwante studie van dezelfde groep onderzoekers die op 12 juli werd gepubliceerd, beoordeelde niet alleen de rotatiesnelheid, maar ook de beweging en locatie van de as van de aarde. Soja en zijn collega's ontdekten dat dezelfde herverdeling van water en massa, veroorzaakt door smeltende poolkappen, bovendien de rotatie-as van de planeet verschuift - mogelijk met een paar meter per eeuw.
Er zijn beperkingen aan beide onderzoeken. RCP 8.5 wordt bijvoorbeeld over het algemeen beschouwd als een verouderde en onwaarschijnlijke projectie voor toekomstige opwarming en gemodelleerde gegevens gaan gepaard met een zekere mate van onzekerheid. Toch laten de twee wetenschappelijke artikelen zien hoe diep de gevolgen van klimaatverandering weerklinken.
"Wij mensen hebben een grotere impact op onze planeet dan we beseffen", aldus Soja in het persbericht. "Dit legt natuurlijk een grote verantwoordelijkheid op ons voor de toekomst van onze planeet."
