“Dit is de rex der rexen,” aldus de Canadese onderzoeker Scott Persons. “Er zijn aanzienlijke verschillen tussen tyrannosaurussen. Sommige individuen waren forser dan anderen. Scotty is een voorbeeld van zo’n fors exemplaar. Zorgvuldige metingen van de benen, heupen en zelfs schouders wijzen uit dat Scotty langer was dan elke andere tyrannosaurus rex (die tot op heden is teruggevonden, red.).” 

De vorige recordhouder was Sue, een tyrannosaurus rex met een lengte van 12,3 meter. Deze dino woog zo’n 5.654 kilogram. 

Scotty is niet alleen de grootste tyrannosaurus rex ter wereld. “Hij is ook de oudst bekende”, aldus de Canadese wetenschapper. “Je kunt een idee krijgen van hoe oud een dinosaurus is door in de beenderen te zagen en de groeipatronen te bestuderen”. Uit de onderzoeksresultaten bleek dat Scotty ongeveer dertig jaar oud was toen hij 66 miljoen jaar geleden stierf. “Dat is uitzonderlijk lang”, aldus Persons. 

De grootste dino ter wereld wordt bewaard in het Royal Saskatchewan Museum in Canada.

Archeologen stoten op schat in Mexico en denken dat ze allereerste graftombe Azteekse keizer op spoor zijn - HLN.be

De ontdekking gebeurde niet in een afgelegen of onontgonnen gebied, maar midden in het centrum van het drukke Mexico-Stad. Meer bepaald aan de voet van de bekende Templo Mayor. Dat was 500 jaar geleden de belangrijkste tempel van de Azteekse hoofdstad Tenochtitlan, in de periode dat de machtigste heerser van het rijk aan de macht was.

Aardbeving in Mexico leidt tot ontdekking van 900 jaar oude tempel

Heiligdommen

De tempel was een gigantisch complex van 60 meter hoog, dat beschouwd werd als het middelpunt van de aarde. Bovenaan stonden twee heiligdommen: een voor de oorlogsgod Huitzilopochtli en een voor de regengod Tlaloc. Bij een van de vele uitbreidingen van de tempel - in 1487 - zou een van de grootste massaoffers plaatsgevonden hebben uit de geschiedenis van de beschaving, waarbij naar schatting 4.000 mensen het leven lieten. De tempel werd uiteindelijk verwoest tijdens de verovering van Mexico door Hernán Cortés in 1521.

De resten kwamen in 1978 tevoorschijn tijdens een verbouwing op het centrale plein van Mexico-Stad. En het is aan de voet van de tempel dat archeologen nu hun ongeziene vondst hebben gedaan: rijkelijke offergaven die zouden kunnen wijzen op een koninklijke begraafplaats. (lees hieronder verder)

Het gaat onder meer om de resten van een luxueus versierde jaguar, verkleed als krijger, een kleine jongen van een jaar of negen die gekleed is als Azteekse oorlogs- en zonnegod - met een jaden ketting en vleugels van havikbeenderen - en een set vuursteenmessen die versierd zijn met parelmoer en edelstenen. De offergaven werden vijf eeuwen geleden neergelegd door Azteekse priesters op een cirkelvormig platform voor de tempel, een plek waar zich volgens de vroegste overleveringen de rustplaats zou bevinden van Azteekse keizers.

“We hebben nu enorme verwachtingen”, zegt het hoofd van de groep archeologen die er aan het werk is - Leonardo Lopez Lujan - aan persbureau Reuters. “Naarmate we dieper graven, zullen we vermoedelijk nog veel meer rijkelijke objecten vinden.” (lees hieronder verder)

Vooral de vondst van de jaguar blijkt opwindend. Die zat in een grote stenen doos, waarvan nog maar een tiende is opgegraven en die nu al een ware schatkist blijkt te zijn. Het dier draagt een houten gravure op de rug met het embleem van de god Huitzilopochtli. Bovenop liggen offergaven uit de zee, zoals schelpen, zeesterren en koraal. Die kunnen verwijzen naar de onderwaterwereld waar de zon volgende de Azteken ’s nachts doorheen reisde. De rode lepelaar – een vogel uit de familie van de flamingo’s – die gevonden is, wordt dan weer geassocieerd met heersers en krijgers en zou hun geest voorstellen in hun tocht naar de onderwereld.

Broers

Tientallen jaren na de verovering van Mexico, brachten enkele geschiedschrijvers verslag uit van de begrafenisrites van drie Azteekse heersers: drie broers die heersten van 1469 tot 1502. Volgens die verslagen werden hun gecremeerde resten neergelegd op of vlakbij het cirkelvormige platform aan de tempel, voorzien van rijkelijke offergaven en de harten van geofferde slaven.

13 jaar geleden werd vlakbij het platform een gigantische monoliet gevonden van een aardgodin. Daarop stond een inscriptie die overeenkwam met het jaar 1502, het jaar waarin de jongste broer en machtigste heerser die de Azteken ooit kenden – Ahuitzotl – stierf. (lees hieronder verder)

Volgens Elizabeth Boone – een expert in het oude Mexico aan Tulane University in New Orleans – zou de dood van Ahuitzotl gepaard gegaan zijn met een grootse begrafenis en zou de jaguar de koning kunnen voorstellen als onbevreesd krijger. “Hij kan goed in die stenen kist begraven liggen”, klinkt het.

De offergaven werpen ook een blik op hoe mobiel de Azteken waren. Ze zouden een beschaving van krijgers geweest zijn die naburige koninkrijken binnenvielen en onderwierpen, een beetje zoals de Spartanen in het oude Griekenland. Zo kwamen de zeesterren bijvoorbeeld uit de Stille Oceaan, terwijl het jade van Centraal-Amerika afkomstig was, ter hoogte van het huidige Honduras.

Budget

Verwacht wordt dat de opgravingen nog zeker enkele maanden zullen duren. De wetenschappers zullen het daarbij niet makkelijk krijgen, want de nieuwe regering van Mexico heeft het budget van het project met 20 procent verminderd voor dit jaar, dixit de archeologen. Bijna iedereen van het 25-koppige team is al niet meer betaald sinds december.

DE LIJST MET BUITENAARDSE OFFICIEREN ( VIDEO )

Hoeveel bewijs is er nog nodig, voordat men in mainstream land gaat toegeven dat er buitenaards leven is (geweest) op Mars en andere locaties. 

De lijst met buitenaardse officieren van NASA met bijbehorende ruimteschepen bewijst dat wij maar met een fractie  bekend zijn met wat er werkelijk in de ruimte gebeurt.

Het beste bewijsmateriaal voor leven op Mars is nog altijd afkomstig van NASA. 

Soms is het even gemakkelijk te ontdekken, omdat een gecrasht ruimteschip meestal niet altijd mooi aan de oppervlakte ligt, maar gedeeltelijk begraven. 

Maar, voor ervaren ufologen zoals Scott Waring, is het mogelijk om deze objecten op te sporen op de foto’s van NASA en het object op de foto voor een deel scherper zichtbaar te maken. 

Het begint met een foto van één van de Rovers die er als volgt uit ziet. 

Het bekende Mars landschap, met in de verte iets dat uitsteekt boven de heuvelrand.

Wanneer we dat object wat dichterbij halen, dan krijgt het een bekende vorm.

En als Scott klaar is met het verbeteren van de foto, dan ziet het er uiteindelijk als volgt uit en zien we dat we hier te maken hebben met een klassieke of retro ufo.

En als dit nu het enige gecrashte ruimteschip op Mars zou zijn, dan zou je misschien nog kunnen twijfelen, maar er zijn in de loop der jaren meer objecten waargenomen op de rode planeet die niet anders uitgelegd kunnen worden dan als gecrashte ruimteschepen. 

In 2016 publiceerden wij de volgende opnames van een gecrasht ruimteschip op Mars.

Beelden die later viraal gingen en werden opgepikt door de wereldpers.

Een jaar later, in 2017, duikt er weer een NASA foto op waarop duidelijk een soort gecrasht ruimteschip op Mars is te zien.

Het wordt zo langzamerhand een onhoudbare zaak voor NASA om nog langer te ontkennen dat er geen tekenen van leven worden gevonden op Mars. Zoals wij eerder deze week een artikel publiceerden met daarop een object, gevonden op Mars, dat onmogelijk natuurlijk kan zijn waarmee door NASA eigenlijk al is toegegeven dat buitenaards leven bestaat. 

Bij dat alles komt natuurlijk ook ander soort bewijs zoals dat geleverd is door de Engelse hacker Gary McKinnon. We hebben eerder al uitgebreid geschreven over deze man en de zaken die  hij ontdekte.

Eén van de meest opmerkelijke dingen die Gary ontdekte was een lijst met buitenaardse officieren en schepen met namen die nergens op aarde zijn te traceren. En dat ze onvindbaar zijn is omdat het namen zijn van ruimteschepen van degeheime ruimtevloot.

Naast bovengenoemde lijsten kwam Gary ook afbeeldingen tegen. Echter, omdat dit alles plaatsvond een kleine 20 jaar geleden toen wij nog geen snel internet hadden en Gary verbinding had via een 56k modem, was het niet mogelijk om afbeeldingen van 2 mb of groter te downloaden.

De oplossing die Gary toen bedacht is om controle te nemen over een computer in de NASA gebouwen en daar op een scherm een afbeelding te downoaden. Hij was een heel eind op weg en zag wat er op stond toen iemand bij NASA in de gaten kreeg dat er iets vreemds met die computer aan de hand was omdat de muis vanzelf over het scherm bewoog en werd de verbinding verbroken.

Maar, wat Gary zag was een groot cilinder-/sigaarvormig schip dat er ongeveer uit zag als op de volgende afbeelding die is gemaakt op basis van de beschrijvingen van Gary. Deze vorm ruimteschepen komen we ook vaak tegen op aarde.

Tegenwoordig hoor je weinig meer van Gary McKinnon en daarom is het volgende interview wat Gary enkele dagen geleden deed met Richard Dolan heel bijzonder en hier is precies te horen hoe Gary te werk ging om de lijst met buitenaardse officieren te bemachtigen.

The recent spate of anomalous noises heard worldwide continues this month as residents of a small town in Michigan report hearing and even feeling a strange, unexplained hum. The hum or vibration is reportedly strong enough to rattle homes, cause glasses of water to ripple Jurassic Park-style, and even crumble the foundations of homes. What could be causing such a powerful vibration throughout Michigan?

Hopefully not a wayward Tyrannosaur.

For now, there are very few theories as to what could be causing the mysterious vibration which seems to be centered around the township of Canton, just west of the former post-apocalyptic dystopia and current mid-gentrification dystopia of Detroit. The U.S. Geological Survey has verified that there has been no seismic activity in the area which could explain the vibration or hum, leaving city officials in Canton to guess the mysterious tremor and noises could be related to either utilities, a nearby landfill, or even traffic on local highway I-275. However, Canton residents don’t buy any of those explanations and say the mysterious vibration sounds different from usual industrial noises and has been increasing in frequency and prevalence lately.

The Canton township municipal complex which includes town hall.

Longtime Canton resident Mackey Howell says in his twenty years in the township, he’s heard and felt the vibrations from local transportation arteries for years but this latest hum somehow seems different:

I’m familiar with all those sounds – the airport, the train, and (the sound) I-275 makes – this is something is very different. I don’t think I’ve ever experienced it during the daytime. Its disturbing. We’ve had pictures actually fall off the wall.

The hum has been reported since the 1970s, but many Canton residents agree with Howell that this latest iteration is anomalous and seems to be getting louder in recent weeks. Some people have even reported feeling pressure changes in their inner ears at the same time they hear and feel the mysterious vibration. Oddly enough, some North Carolina residents reported the same sensation in conjunction with good ol’ fashioned mystery booms in the area just a few weeks prior. 

I’ve been tracking and researching these anomalous, Earth-rattling noises for over two years now, and like city officials and public safety agencies everywhere, I’m at a complete loss to explain what forces or phenomena may be behind these events. Are these unknown natural occurrences, or are they caused by some man made activity? Reports of anomalous noises and mysterious booms date back centuries, but the unbelievably high number of reports lately suggests either that the phenomenon is increasing or intensity or that a new cause is afoot. What’s behind all of these anomalous noises? Is the Canton hum related in any way to more well-known hums like the Taos hum or Windsor hum?

Stay tuned.

'Project Blue Book' Season 2 Possible Air Date, Plot, Other Story Details Unveiled

25-03-2019 om 14:46 geschreven door peter  

Is science fiction the cause of mysterious lights seen at night in Delamere Forest?

Is science fiction is the cause of mysterious lights seen at night in Delamere Forest?

PEOPLE living in and around Delamere Forest have been puzzled by the appearance of strange, eerie lights among the trees.

They could be forgiven for think that the forest was the sight of a UFO encounter - and they would not be far wrong.

The forest is increasingly being used as a location for films and television - including a BBC adaptation of War of the Worlds and a new Netflix series called The Stranger.

Photo: Lee Cartwright

The dense forest has recently been used as a backdrop for dramatic scenes of an alien invasion for the latest adaptation of H G Wells classic War of the Worlds.

The Peter Harness' three-part adaptation the sci-fi classic will be screened on BBC One later this year.

And more recently, a car chase was filmed for The Stranger, a series due to be shown on Netflix later this year starring Hannibal and The Hobbit actor Richard Armitage.

Few details are available about the eight-episode series, based on Harlan Coben’s novel, but the synopsis from Netflix reads: “ A secret destroys a man’s perfect life and sends him on a collision course with a deadly conspiracy in this shocking thriller.

“Adam Price has a good life, two wonderful sons, and a watertight marriage - until one night a stranger sits next to him in a bar and tells him a devastating secret about his wife, Corinne.

“Soon Adam finds himself tangled in something far darker than even Corinne’s deception, and realises that if he doesn’t make exactly the right moves, the conspiracy he’s stumbled into will not only ruin lives — it will end them.”

One resident of Station Road said weird sightings were becoming more common in the forest.

He said: There's a weird chunky looking prop with bright lights attached to it, suspended from a really high crane arm, above white gate car park and its mega bright. It lit up my house through the windows yesterday. I've not heard any noises or anything though."

The lights certainly piqued residents' curiosity.

Posting in the Delamere and Oakmere Facebook group, Jacqui Brooks asked: "What are the giant lights on the skyline over far side of the forest for?"

Sarah Evans said: "We have wondered every morning/evening...query aliens abduction of locals, building, concerts..can tell kids the truth now?"

Ellen Piercy replied: "Nah, stick with the aliens story, MUCH more exciting."

Others described the filming as "exciting" and "very, very bright".

The forest has become popular with television and film producers, with episodes of ITV drama Cold Feet filmed there recently.

Residents have been told filming is permitted until 1am.

UFO Over Berlin Airport Moves Out Of Way Of Jet, March 6, 2019, UFO Sighting News.

Date of sighting: March 6, 2019

Location of sighting: Berlin, Germany

Source: MUFON #99333

 

Here is an interesting report from MUFON today. A person took some photos and noticed a UFO two of the photos. What looks like a ring UFO may be one solid craft with the top center having a dark tinted dome window area on it. The UFO moves it position when it notices the passenger jet approaching it. This makes me think there is a possibility of the UFO having shown up on airport radar. The UFO itself was probably hovering over Berlin Brandenburg Airport for a few minutes before it was forced to move out of the path of a jet. 

 

When you compare the size of the jet, lets say for comparisons sake its a 747 which is 76.3 meters long. Then this UFO is 30% the diameter of the jet, making the UFO 22.89 meters across. Notice how the UFO takes on the color of the sky behind it? Its tying to go unnoticed. The ships outer hull reflects the colors around it.

 

A lot of UFOs have been recorded over Airports over the years. I guess anything that flies has the newest and highest tech for safety reasons and that makes it worth investigating by aliens.

Mind Blowing Structures On Earths Moon In NASA Photo, March 2019, UFO Sighting News.

Date of discovery: March 25, 2019
Location of discovery: Earths Moon
Source NASA photo: 

• https://www.lpi.usra.edu/resources/apollo/frame/?AS15-P-9583
  
  

Sure some of you have heard about my discovery of the Yoda face on Earths moon a few years ago, (Click here to see Yoda post) but did you know there is so much more there? Its true, but to see the structures there, you must follow my instructions below. 

1. Go to URL and lift photo from site to desktop. 
2. Open photo on desktop. 
3. Goto tools bar at top (IOS mac). Then hit size. 
4. Change size, enlarge until photo is 10MB. Then close photo. 
5. Now Open photo in any photo program and add contrast like its going out of style...that means a lot. 
6. Now save photo and start searching it for structures, you will have to use zoom and have to look carefully. 

You need to do this because NASA added too much light to the photo on purpose in order to cause many of the ares of the photo to appear as white/grey and unclear. Thus bring it back into the proper light and focus creates the original photo as it was first taken. 

You will notice that the aliens built the structures square partitions. Much like remaking a house and moving the parts to the location to create it. This may be proof that the structures were created somewhere else, then brought to the moon to put together. 

Do not do this if you are sensitive. It might be overwhelming to suddenly go from believing to knowing. I do not mean to frighten anyone, but only to bring the truth to light. I actually found this several weeks ago, but hesitated till now to publish it. I was worried some people may panic. The biggest fear is not aliens attacking earth, its that they exist when science says they should not. It causes the person to call into question everything they ever learned in school, church, TV, from friends...and how aliens must have already influenced the direction humanity is currently traveling without anyone ever knowing. Its a bit deep of a plunge, but it must be taken. I did, I remember that day well. Thats why I never say I believe in aliens...it sounds like I have doubt, but I don't. I know they exist.

The Navy Plans to Put HELIOS Laser Weapon on Destroyer by 2021

HELIOS will be capable of downing drones and “burning boats”.

By Kyle Mizokami

LOCKHEED MARTIN

Pew-pew-pew is coming soon-soon-soon.

The U.S. Navy plans to put a laser weapon on a warship by 2021. The High Energy Laser with Integrated Optical-dazzler and Surveillance (HELIOS) system, or HELIOS, is a defensive weapon system designed to burn boats and shoot down unmanned drones. The weapon will go to sea with a guided missile destroyer assigned to the Pacific Fleet in two years' time, the Navy says.

The service placed an order for HELIOS in January 2019. The $150 million contract, awarded to Lockheed Martin, calls for the company to deliver two systems. According to a company press release, one will go to White Sands Missile Range in New Mexico for testing. USNI News says the Navy will install the other on a Arleigh Burke-class guided missile destroyer.

HELIOS is a 60-kilowatt laser system, meaning it has twice the power of the AN/SEQ-3 Laser Weapon System, or LaWS installed on the USS Ponce in 2014. HELIOS is billed as a weapon that can burn small speed boats of the type Iran deploys in armed swarms, and can torch unmanned aerial vehicles out of the sky. Alternately—and perhaps to avoid an international incident—HELIOS can simply “dazzle” a UAV’s electro-optical sensors, damaging them and preventing them from performing their mission.

Here’s a simple example of this theory, in which a laser used during tattoo removal damages a digital camera sensor:

HELIOS has a long-range intelligence, surveillance, and reconnaissance capability. While LockMart doesn’t spell out the details, we can surmise that the aiming system for the laser weapon/dazzle is probably capable of high-definition, high-powered digital magnification, allowing a ship fitted with it to closely watch nearby threats.

Many weapons already deployed on U.S. Navy warships, including the Phalanx close-in weapon system and the Rolling Airframe Missile (RAM), have a similar capability against small boats and drones as HELIOS while also being capable of taking on larger, faster aircraft and missiles. Range is also comparable.

Where a laser weapon like HELIOS shines, literally, is its ability to fire a theoretically unlimited number of shots using the destroyer’s onboard electrical generation systems. Phalanx, on the other hand, is limited to 20 to 30 seconds of continuous firing, while RAM is limited to 21 missiles aboard the Mk. 49 Guided Missile Launching System.

HELIOS is not a quantum leap above existing systems, but then again, early guns like the matchlock were in some ways inferior to the bow and arrow. Eventually, as firearms technology progressed, the gunpowder gun progressed to the point where it was clearly superior. As laser weapons become more powerful, they could quickly become much more effective than conventional gun and missile weapons.

Archaeologist debunks alien influence, other conspiracy theories in archaeology

Have you heard the one about the aliens and the pyramids? Or what about the technologically advanced but tragically lost city of Atlantis?

Chances are that most of us have encountered at least one such story—a tale that tries to explain the past in a way that can sound scientific, but in doing so ignores the evidence and methods of science.

Why is this alternative archaeology so popular? And how do we tell fact from fiction?

Assistant Professor Matthew Peeples, co-director of the School of Human Evolution and Social Change's Center for Archaeology and Society and an archaeologist of the Southwest U.S., is no stranger to the weirder side of his field. He has investigated false claims and has even been accused of covering up the truth.

For Arizona Archaeology and Heritage Awareness Month, he sat down to discuss the background on these conspiracy theories, including one surrounding a petroglyph at the nearby Deer Valley Petroglyph Preserve.

Answers have been edited for length and clarity.

Question: What are some examples of outrageous archaeological narratives in pop culture?

Answer: Probably the biggest out there involves the notion that intelligent alien life visited human populations in the ancient past and either influenced or directed the development of human cultures. This idea is pervasive in science fiction going back to early 20th-century authors like H.P. Lovecraft, but has gained popularity in more recent years through a deluge of books and TV shows like "Ancient Aliens."

These ideas are not supported by scientific evidence, but they've become so prevalent that many people believe there must be something to them. To use the Great Pyramids in Egypt as an example, archeologists have clearly shown how these structures fit in a broader tradition of smaller stone structures and earlier attempts at pyramid construction. The building technology is impressive, but we don't need to invoke aliens to explain it.

Another popular notion is that professional archaeologists themselves are actively hiding the truth about the past. I've personally had people accuse me of being part of a widespread cover-up or conspiracy. This trope shows up again and again in pop culture through shows like "The X-Files" or "Stargate." In reality, archaeologists love to test and retest each others' ideas about the past using new data and discoveries, which is what pushes the science forward.

Q: What are the myths surrounding the Deer Valley petroglyphs?

A: I wasn't aware of this until visitors at the preserve asked about it, but there was a mention of Deer Valley in a book published in the 1970s claiming to show evidence of Europeans visiting North America prior to the arrival of Christopher Columbus or the Viking colonization of Newfoundland.

The book featured drawings of rock art from throughout North America supposedly depicting boats from various places in ancient Europe and the Near East. One, from the Deer Valley Petroglyph Preserve, was said to depict a Punic sailing vessel along with the words "the ship" in Iberian Punic.

I worked with a group of honors students in my "Frauds, Myths and Mysteries" class to track down this claim and assess it. It took us quite a while to locate the petroglyph in question, largely because the drawing bore little resemblance to the actual petroglyph. We took high-resolution photos and made a 3-D model of the petroglyph, and we were able to show that the features that made both the supposed inscription and ship "convincing" were either exaggerated or were absent in the actual petroglyph (which archaeologists had previously suggested may have been a butterfly).

Q: When did conspiracy theories like these first come about? And why are they still popular today?

A: False archaeological claims like these have a really long history. There are accounts of a supposed discovery of the tomb of King Arthur and Guinevere by monks at Glastonbury Abbey in 1191, shortly after the abbey was burned in a massive fire. The story attracted a lot of pilgrims who funded the reconstruction of the church, but more recent archaeological work has shown that the pre-Christian cemetery dated many centuries later than would be expected were there truth to this story. Most historians now chalk this up to a publicity stunt by the abbey. There are even similar references to such claims going back to at least the second century A.D.

I think these claims are still popular today for a number of reasons. First, there is a lot of money to be made from selling pseudoscientific ideas to the public, as is evidenced by the numerous books and TV shows that keep popping up. A lot of these ideas are also tied to nationalism and various other kinds of group identities. People have a desire to claim that their ancestors were the first to arrive in a new land or develop some advanced technology, claims that have even been used to justify war and invasion.

Q: How do archaeologists separate plausible arguments from pseudoscience? What are the challenges in that?

A: Archaeology is all about the systematic and scientific study of human societies based on the stuff they leave behind in context. A lot of pseudoscientific ideas attempt to put on the trappings of science by using the jargon but completely ignore the scientific process of formal observation and evaluation. Plausible arguments need to be supported by evidence rather than simply asserted, and the methods and data used should be made available for scrutiny.

Be suspicious if someone is making conspiratorial claims that scientists' lack of acceptance for their ideas is about suppression of the truth. Relying on high-quality, peer-reviewed sources will also ensure that people with the relevant expertise have had a chance to vet the work. I'm a fan of a set of tools Carl Sagan published as a "baloney detection kit," which are a series of questions you can ask yourself about a given claim to help you fortify yourself against falling for pseudoscientific claims.

Q: Where can the public look for accurate archaeological information?

A: If you're interested in archaeology here in Arizona, there are a lot of excellent groups and organizations you could get involved with. The Arizona Archaeological Society has chapters throughout the state that offer talks, tours and even opportunities to work on archaeological projects. There are also nonprofits like Archaeology Southwest in Tucson that provide high-quality information for non-specialists on the archaeology of the region.

2020 Mars Helicopter Could Open Alien Skies to Exploration

By Mike Wall 

The little craft's demonstration mission could lead to big things.

The 4-lb. Mars Helicopter will travel to the Red Planet with NASA's next Mars rover, which is scheduled to launch in mid-2020.

A few brief hops in the Martian air two years from now could help open alien worlds to an entirely new kind of exploration.

An autonomous mini-helicopter will fly with NASA's Mars 2020 rover mission, which is scheduled to launch in July of that year and land on the Red Planet in February 2021. 

The bantam chopper is a stripped-down technology demonstration, and it will make a maximum of five short sorties in the Martian atmosphere. Success in this pioneering work would be a big deal, extending the reach of humanity's robotic explorers, which are currently restricted to the surfaces of alien worlds or the dark realms far above them.

• Related: NASA's Mars Rover 2020 Mission in Pictures (Gallery)

"We envision helicopters opening doors to new types of exploration on Mars," Håvard Grip, flight-control and aerodynamics lead for the Mars Helicopter, said Wednesday (March 20) during a presentation with NASA's Future In-Space Operations (FISO) working group.

One day, more-advanced versions could serve as scouts for rovers or explore the Red Planet on their own, added Grip, who's based at NASA's Jet Propulsion Laboratory and the California Institute of Technology, which are both in Pasadena. 

"In the future, we could imagine doing things like [engaging in] regional exploration using multiple helicopters or going to inaccessible areas or biologically sensitive areas using small helicopters," he said.

The Mars Helicopter weighs 4 lbs. (1.8 kilograms) and has a body about the size of a softball. It carries a range of avionics and communications gear, a small solar panel, rechargeable lithium-ion batteries, "survival heaters" to keep its electronics warm through the frigid Martian night, and a navigation camera.

The helicopter doesn't have any science instruments, but it is outfitted with a high-resolution color imager.

"That's, so to speak, the payload," Grip said. "That's what we [use to] take pretty pictures and send them back to Earth."

The helicopter will travel to Mars attached to the belly of the car-size 2020 rover, which will hunt for signs of ancient Red Planet life and collect and store samples to return to Earth in the future, among other tasks.

A month or two after the rover lands on the Red Planet, the chopper will drop down and hit the dirt itself. The little vehicle will then make a series of short flights, each of which will last about 90 seconds and reach a maximum altitude of 16.5 feet (5 meters) or so, Grip said.

These sorties will be made between 330 feet and 3,300 feet (100 to 1,000 m) away from the rover — far enough away to pose no collision danger, but close enough to be in communications range. (The helicopter will talk to its handlers on Earth via the rover.)

Success would be quite an achievement, considering that the Martian atmosphere is just 1 percent as dense as that of Earth at sea level. Cruising just above the Martian surface is equivalent to flying at an altitude of 100,000 feet (30,000 m) here on Earth, more than twice as high as any helicopter has ever gotten. (The handicap imposed by the thin air is only partially offset by the Red Planet's lower gravity, which is 38 percent that of Earth, Grip said.)

To generate enough lift, the Mars Helicopter sports two stiff rotors that measure 3.9 feet (1.2 m) long — pretty much as big as the team could make them, Grip said. And the rotors will spin at 2,400 revolutions per minute, about 10 times faster than the blades of a chopper on Earth, mission team members have said.

The team has put this design through its paces many times in Mars-like conditions here on Earth, Grip said. Indeed, the little craft is pretty much ready to go.

"The flight model is built and more or less tested," Grip said.

The ultimate test, of course, will come on Mars.

"The Mars Helicopter's initial flight will represent that planet's version of the Wright brothers' achievement at Kitty Hawk and the opening of a new era," Susan Gorton, manager of NASA's Revolutionary Vertical Lift Technology project, which has been working with the Mars Helicopter team, said in a statement last week. 

"For those of us whose research revolves around all things related to flight, that would be a remarkable, historic moment," Gorton added.

Such historic moments may not be limited to Mars' skies. NASA is considering launching a quadcopter lander to Titan, Saturn's huge, haze-enshrouded moon. This mission, called Dragonfly, would fly from spot to spot on Titan, investigating the complex chemistry occurring on the potentially life-supporting moon.

Dragonfly is one of two finalists for a mid-2020s launch slot under NASA's New Frontiers program of medium-cost missions. The other contender is a comet sample-return mission called CAESAR. NASA is expected to announce its selection later this year.

The Mars Helicopter and Dragonfly teams have not collaborated to date, Grip said.

UFO Community Versus Science – When Science Meets Faith In The UFO

24-03-2019 om 23:58 geschreven door peter  

24-03-2019 om 23:43 geschreven door peter  

IT’S OFFICIAL. HUMANS ARE GOING TO MARS. NASA HAS UNVEILED THEIR MISSION.

Humanity has been fascinated by Mars since long before we stepped foot on the Moon. Our planetary neighbor has been the subject of innumerable works of sci-fi and inspired countless dreams of adventure and exploration. Now, after decades of determination, research, and scientific breakthroughs, we’re finally ready to do it: humans are going to Mars. Really.

Last year President Trump issued a mandate for NASA: get people to Mars by 2033. One week later, NASA responded with its most detailed plan to date for reaching the Red Planet, and it details five phases along the road to Mars.

We’re in Phase 0 now, conducting tests at the International Space Station (ISS) and developing partnerships with private space companies. Phase I will span 2018 to 2025 and will include the launch and testing of six SLS rockets. Those rockets will deliver components of the Deep Space Gateway (DSG), a new space station to be built near the Moon to serve astronauts en route to Mars.
After that, Phase II will launch the Deep Space Transport (DST) tube toward the lunar station in 2027, and in 2028 or 2029, astronauts will inhabit the tube for more than 400 days. 

In 2030, Phase III will see the DST restocked with supplies and the Mars crew via SLS rocket. Phase IV, of course, will be the trip itself in 2033. That means we’re just a scant 16 years away from reaching a goal that has eluded every generation that came before us.

Completing the mission within their budget will be a challenge for NASA. That budget is currently about .5 percent of the total U.S. budget. For comparison, it was more than four percent during the Apollo Moon missions.

The mission to Mars includes obstacles beyond budget — keeping astronauts healthy and reasonably happy on the journey is chief among them. Without stopovers between Earth and Mars, astronauts will need to port everything they need with them, including air, food, and water, for a round-trip duration of two or three years.

Mental health is likely to be a concern for Mars astronauts, too, as they will essentially be sealed into the space tube for years at a time, with no ability for an emergency return once they leave Cislunar space. NASA’s HI-SEAS isolation experiment has shown promising results, but it is likely that the journey won’t be possible for everyone.

NASA also has competition in the race to get to Mars. Both Boeing and SpaceX hope to get there first, with SpaceX setting the lofty goal of arriving in 2022.

Ultimately, though, we all benefit from the friendly competition in the race toward Mars and the creative solutions it will almost certainly generate. If private companies work out some of these human challenges before NASA can, the agency can build on their experiences and spend its budget and efforts on other problems. In the end, the goal of putting humans on Mars will have been reached, irrespective of which organization crosses the finish line first.

NASA may send smallsat mission to giant asteroid Pallas

Pallas, third largest asteroid in the asteroid belt and the second such object to be discovered, by the German astronomer and physician Wilhelm Olbers on March 28, 1802. The asteroid was named after Pallas Athena, the Greek goddess of wisdom.

Pallas is 512 kilometers (318 miles) in diameter, somewhat smaller than 4 Vesta. It is likely a remnant protoplanet. The asteroid's orbit is unusually high in inclination to the plane of the asteroid belt, and its eccentric orbit is nearly as large as that of Pluto, making Pallas almost inaccessible to spacecraft.

NASA won't make the final decision on funding this mission until mid-April. The so-called Athena mission will be competing with 11 other SmallSat and CubeSat mission proposals, according to Arizona State University planetary scientist Joseph O’Rourke, Athena’s principal investigator, reports Forbes.

If the mission is approved, it will follow in the path of the Dawn Mission that explored two other giant objects in the asteroid belt, Vesta and Ceres. The Dawn Mission ended last year.

"Pallas is really the only other object in the main asteroid belt that's like Vesta and Ceres … not just an asteroid, but a protoplanet, a real world," said O'Rourke, reports Space.com. "I see this as a way to go do a lot of the same science that Dawn did, but at a dramatically cheaper price, and Pallas is the sort of place that might be worth sending a much bigger mission to someday."

Athena would hitch a ride with Psyche Mission

If selected, Athena would launch in August 2022, riding piggyback along with the NASA Psyche Mission. Psyche is a very interesting mission in its own right. It will explore the origin of planetary cores by studying the metallic asteroid,16 Psyche. 16 Psyche is the heaviest known M-type asteroid and is thought to be the exposed iron core of a protoplanet.

"We would race Psyche to Mars, use Mars as a gravity assist, and then catch Pallas," O'Rourke said. The Pallas flyby would come about a year after the launch.

Psyche is one of the ten most massive asteroids in the asteroid belt. It is over 200 kilometers (120 miles) in diameter and contains a little less than 1 percent of the mass of the entire asteroid belt.

A protoplanet is a large planetary embryo that originated within a protoplanetary disc and has undergone internal melting to produce a differentiated interior. Vesta is also a protoplanet. On January 4, 2017, the Psyche mission was chosen along with the Lucy mission as NASA's next Discovery-class missions.

NASA May Send a Smallsat Mission to the Giant Asteroid Pallas

By Meghan Bartels 

If selected, the mission would launch in August 2022, riding piggyback with NASA's Psyche mission that is bound for an asteroid made nearly entirely of metal. "We would race Psyche to Mars, use Mars as a gravity assist, and then catch Pallas," O'Rourke said. The Pallas flyby would come about a year after the launch.

During the maneuver, Athena would take an extremely precise measurement of just how massive Pallas is and snap a bunch of images of the asteroid, which scientists could then use to piece together how water and impacts may be shaping its surface. "There's hints on the ground that it might have bright spots like Ceres," O'Rourke said, referring to features Dawn scientists believe may represent salty patches on that asteroid's surface. "So it could potentially be a place with a lot of interesting chemistry going on."

With a price tag about a tenth the size of the $467 million Dawn mission, and a single flyby instead of long-term visits, Athena likely won't produce as comprehensive a package of science results as the Dawn mission has. But it should be enough to begin to understand this little-known world, according to O'Rourke. "This mission is going to pluck a lot of the low-hanging fruits scientifically," he said. "Hopefully, it will showcase the fact that we're beginning a new era of planetary exploration," in which cheap probes can precede flagship missions.

The Athena team would also post all its images soon after downloading them from the spacecraft. "In fact, one of my biggest worries about the mission is that the mission team will get scooped on the science," O'Rourke said. "Everyone will be able to make our discoveries right along with us, so we'd better be ready to bang out some papers."

NASA's decision, whether it chooses Athena or not, will come just a few months after the first tiny satellites to venture beyond Earth's orbit proved just how valuable small spacecraft can be to planetary scientists. Two cubesats the size of bread boxes hitchhiked with NASA's Mars InSight lander as the Mars Cube One (MarCO) mission. The little satellites captured stunning images of the Red Planet and in November, they acted as communications relays, saving scientists from hours of agony about whether the main spacecraft had touched down safely.

Athena would be larger — the size of a miniature refrigerator and about 400 lbs. (180 kilograms) — but would still represent a new mindset for planetary science, one that relies on dramatically less complicated spacecraft than traditional missions.

"I think the asteroid belt is a really great target for smallsats because there are so many targets that are interesting, we're not going to send these half-billion-dollar-plus missions to every single one," O'Rourke said. "So we have to get good at building these small flight systems that are versatile and can be used to explore."

Why Nuclear Fusion Is Always 30 Years Away

By Nathaniel Scharping

Nuclear fusion has long been considered the “holy grail” of energy research. It represents a nearly limitless source of energy that is clean, safe and self-sustaining. Ever since its existence was first theorized in the 1920s by English physicist Arthur Eddington, nuclear fusion has captured the imaginations of scientists and science-fiction writers alike.

Fusion, at its core, is a simple concept. Take two hydrogen isotopes and smash them together with overwhelming force. The two atoms overcome their natural repulsion and fuse, yielding a reaction that produces an enormous amount of energy.

But a big payoff requires an equally large investment, and for decades we have wrestled with the problem of energizing and holding on to the hydrogen fuel as it reaches temperatures in excess of 150 million degrees Fahrenheit. To date, the most successful fusion experiments have succeeded in heating plasma to over 900 million degrees Fahrenheit, and held onto a plasma for three and a half minutes, although not at the same time, and with different reactors.

The most recent advancements have come from Germany, where the Wendelstein 7-X reactor recently came online with a successful test run reaching almost 180 million degrees, and China, where the EAST reactorsustained a fusion plasma for 102 seconds, although at lower temperatures.

Still, even with these steps forward, researchers have said for decades that we’re still 30 years away from a working fusion reactor. Even as scientists take steps toward their holy grail, it becomes ever more clear that we don’t even yet know what we don’t know.

For Every Answer, More Questions

The Wendelstein 7-X and EAST reactor experiments were dubbed “breakthroughs,” which is an adjective commonly applied to fusion experiments. Exciting as these examples may be, when considered within the scale of the problem, they are only baby steps. It is clear that it will take more than one, or a dozen, such “breakthroughs” to achieve fusion.

“I don’t think we’re at that place where we know what we need to do in order to get over the threshold,” says Mark Herrmann, director of the National Ignition Facility in California. “We’re still learning what the science is. We may have eliminated some perturbations, but if we eliminate those, is there another thing hiding behind them? And there almost certainly is, and we don’t know how hard that will be to tackle.”

We will almost certainly get a better perspective on the unknown problems facing fusion sometime in the next decade when an internationally-backed reactor, intended to be the largest in the world, comes to fruition. Called ITER, the facility would combine all we have learned about fusion into one reactor.

It represents our current best hope for reliably reaching the break-even point, or the critical temperature and density where fusion reactions produce more power than is used to create them. At the break-even point, the energy given off when two atoms fuse is enough to cause other atoms to fuse together, creating a self-sustaining cycle, making a fusion power plant possible.

Perhaps inevitably, however, ITER has fallen prey to setbacks and design disputes that have slowed construction. The U.S. has even threatened to cut its funding for the project. It is these sorts of budgetary and policy hesitations that could ensure we continue saying fusion is 30 years away, for the next three decades.

In the face of more immediate challenges, from health epidemics to terrorism, securing funding for a scientific long bet is a hard sell. A decades-long series of “breakthroughs” that lead only to more challenges, compounded by pervasive setbacks, have diluted the fantastic promise of a working fusion reactor.

What Exactly Is Fusion?

Reliably reaching the break-even point is a twofold problem: getting the reaction started and keeping it going. In order to generate power from a fusion reaction, you must first inject it with sufficient energy to catalyze nuclear fusion at a meaningful rate. Once you have crossed this line, the burning plasma must then be contained securely lest it become unstable, causing the reaction to fizzle.

To solve the issue of containment, most devices use powerful magnetic fields to suspend the plasma in midair to prevent the scorching temperatures from melting the reactor walls. Looking something like a giant doughnut, these “magnetic containment devices” house a ring of plasma bound by magnetism where fusion will begin to occur if a high enough temperature is achieved. Russian physicists first proposed the design in the 1950s, although it would be decades before they actually achieved fusion with them.

To create a truly stable plasma with such a device, two magnetic fields are required: one that wraps around the plasma and one that follows it in the direction of the ring. There are currently two types of magnetic confinement devices in use: the tokamak and the stellarator.

The differences between the two are relatively small, but they could be instrumental in determining their future success. The main disparity in their design arises from how they generate the poloidal magnetic field — the one that wraps around the plasma. Tokamaks generate the field by running a current through the plasma itself, while stellarators use magnets on the outside of the device to create a helix-shaped field that wraps around the plasma.

According to Hutch Neilson of the Princeton Plasma Physics Laboratory, stellarators are considered more stable overall, but are more difficult to build and suffer from a lack of research. Tokamaks, on the other hand, are much better understood and easier to build, although they have some inherent instability issues.

At the moment, there is no clear winner in the race between the two, as neither appears to be close to the “holy grail.” So, due to lack of a victor, researchers are building both.

“There is a lack of a solution at this time, so looking at two very realistic and promising configurations for closing that gap is the responsible thing to do,” says Neilson.

Currently, the largest fusion reactor in the world is the Joint European Torus (JET), a tokamak based in England and supported by the European Union. JET was commissioned in the 1970s and first came online in 1983 and successfully produced plasma, the first step in achieving fusion.

With a series of upgrades beginning in the late 1980s, JET became the world’s largest fusion generator, and currently holds the record for the most energy produced in a fusion reaction at 16 megawatts. Even so, it has not yet reached the break-even point.

ITER Offers a Way

To reach this all-important milestone, we will likely have to wait for ITER.Latin for “the way,” ITER will be the largest and most powerful fusion generator in the world, and is expected to to cross the break-even point. ITER is projected to produce 500 MW of power with an input of 50 MW, and be able to hold plasma for half an hour or more. That’s enough energy to power roughly 50,000 households.

Based on the tokamak design, the project is the result of a collaboration between the European Union and six other countries, including the U.S., that have pooled resources and expertise to build a reactor that is expected to be the gateway to useable fusion energy.

One of the main issues facing current generators is one of size, says Duarte Borba, a researcher at EUROfusion, and ITER will attempt to overcome this shortfall. As reactors get larger, they become more stable and can achieve higher temperatures, the two key factors in creating fusion.

ITER is meant to be the successor to JET, and will take the technology developed there and apply it on a much larger scale. This includes JET’s tungsten and beryllium divertors, which capture energy in the reactor, as well as the capability to fully control the system remotely. ITER will also use superconducting magnets to create its magnetic field, as opposed to ones made of copper, according to Borba.

Such magnets will reduce the amount of energy consumed by the device and will allow for longer, more sustained plasma production. JET can currently only produce plasma in bursts, as it cannot sustain the high levels of energy use for very long.

Collaboration Is Key

The most important development made by JET and implemented with ITER may not even be scientific, but rather bureaucratic in nature, says Borba. As a project supported by multiple nations, JET forged the path for organizing and implementing a large-scale, decades-long project.

With a projected price tag of $15 billion and a daunting shopping list of complex components, ITER could only exist today as a collaborative effort. Each of the member nations contributes researchers and components, with the hope that the potential benefits will be shared by all.

However, the democratic nature of ITER has significantly slowed down its construction. The goal is to have all of the parts arrive at the same time, but allocating each part to a different country brings in political and economic variables that throw the timing off. When ITER first received formal approval in 2006, it was slated to first achieve fusion in 2016, a date which has since been pushed back at least 10 years. Issues with component construction and design disagreements have been blamed for the delays.

A Worldwide Effort

To achieve a fusion power plant capable of addressing our energy needs, ITER alone is still not enough, according to Neilson. Even though it represents a significant advancement in reactor design, ITER isn’t the end game for fusion research.

If everything goes to plan, ITER will pave the way for another reactor, called DEMO, which will expand the technologies perfected by ITER to an industrial scale, and hopefully prove that nuclear fusion is a viable source of energy.

In the meantime, the new crop of fusion reactors appearing around the world will continue to play crucial roles in the chase for fusion. Far from being redundant, their supplemental research will attack the problem from different angles.

While ITER addresses the issue of scale, fusion projects in Asia are attempting to hold on to plasmas for longer and longer as they probe the benefits of superconducting magnets, Neilson said. Meanwhile, in Germany, the Wendelstein 7-X is pushing the boundaries of the stellarator design, possibly sidestepping issues of stability entirely. Nuclear fusion research has been a mild success in terms of international cooperation, with a growing number of countries determined to contribute their own piece of the puzzle.

Today, there are nuclear fusion experiments operating in the U.S., Germany, United Kingdom, India, France, Japan and several other countries. More reactors are being planned or are currently under construction. Even with the surge of interest, it’s still not enough, says Neilson.

“For a problem as dense and challenging as fusion, you want to have many more experiments trying out different parts of the problem than we actually have,” says Neilson.

More Than a Scientific Problem

Ultimately, the question may be one of funding. Multiple sources said they were confident that their research could progress faster if they received more support. Funding challenges certainly aren’t new in scientific research, but nuclear fusion is particularly difficult due to its near-generational timescale. Although the potential benefits are apparent, and would indeed address issues of energy scarcity and environmental change that are relevant today, the day when we see a payoff from fusion research is still far in the future.

Our desire for an immediate return on our investments dampens our enthusiasm for fusion research, says Laban Coblentz, the head of Communication at ITER.

“We want our football coaches to perform in two years or they’re out, our politicians have two or four or six years and they’re out — there’s very little time to return on investment,” he said. “So when somebody says we’ll have this ready for you in 10 years, that’s a tough narrative to tell.”

In the U.S., fusion research receives less than $600 million in funding a year, including our contributions to ITER. This is a relatively small sum when compared to the $3 billion the Department of Energy requested for energy research in 2013. Overall, energy research represented 8 percent of the total funding the U.S. gave out for research that year.

“If you look at it in terms of energy budgets, or what’s spent on military development, it’s not really a lot of money that’s going to this,” says Thomas Pedersen, division head at the Max-Planck Institut für Plasmaphysik. “If you compare us to other research projects, it seems very expensive, but if you compare it to what goes into oil production or windmills or subsidies for renewables, its much, much less than that.”

Pedersen looks at fusion research in terms of expected inputs and gains. Research into solar and wind power may be relatively cheap, but the payoff pales in comparison to a working nuclear fusion generator.

Always 30 Years Away

However, the finish line has been visible for some time now, a mountaintop that seems to recede with every step forward. It is the path that is obscured, blocked by obstacles that are not only technological, but also political and economic in nature. Coblentz, Neilson and Borba expressed no doubts that fusion is an achievable goal. When we reach it however, may be largely dependent on how much we want it.

Soviet physicist, Lev Artsimovich, the “Father of the Tokamak” may have summed it up best:

“Fusion will be ready when society needs it.”

BUTTE – Many people believe UFOs visit Earth from other planets far, far away. A Montana Tech professor believes UFOs are much closer to home.

“The phenomenon may be our own distant descendants coming back through time to study us in their own evolutionary past,” said Michael P. Masters.

Could UFOs be time travelers from our own future ?

Masters writes about this theory in his newly released book, “Identified Flying Objects.” With a doctorate in anthropology from Ohio State University, Masters uses science to explain why people who report close encounters with aliens always describe them the same way.

“The extra-tempestrial are ubiquitously reported as being bipedal, upright-walking, five fingers on each hand and foot, bi-lateral symmetry that they have two eyes, a mouth a nose, they can communicate with us in our own languages,” said Masters.

Masters understands this study may be considered fringe science, but he defends the research in the book.

“I stand by the product. I’m happy to talk about it with anyone. It’s written for my academic peers as much as it is for anyone in the UFO community,” he said.

Here’s the point in the story where the journalist makes a flippant comment about little green men to show he doesn’t take it that seriously, but the U.S. Defense Department spent $22 million investigating the UFO phenomenon, and that’s why Dr. Masters believes it’s time scientists take a serious approach to the study of this phenomenon.

“The hope is we can begin a new dialogue, get past some of the stigma and not have to defend this as science because it is very scientific as well,” said Masters.

Masters has been on several radio and television programs here and abroad to discuss his book. He will appear on the national radio show Coast to Coast next week.
