EXCLUSIVE: Pentagon ordered to re-investigate 1945 crash of mysterious 'avocado-shaped UFO' dubbed the 'Roswell before Roswell' - as expert reveals eyewitness accounts of the encounter

• Last week President Biden signed a new military spending bill, amended to incorporate a UFO case from 1945
• The sighting involved a crash in New Mexico, about 100 miles from Roswell
• Jaques Vallée, a former contractor for the government's UFO office, wrote a book about the case and described it to DailyMail.com
• Vallée was the inspiration for François Truffaut's character in Close Encounters

By JOSH BOSWELL FOR DAILYMAIL.COM and CHRIS SHARP FOR DAILYMAIL.COM

The government's UFO office has been ordered to re-investigate an alleged 1945 crash of a strange object in New Mexico – dubbed the 'Roswell before Roswell'.

A new military spending bill signed into law by President Biden last week was specifically amended to incorporate the intriguing case into a historic review of UFO incidents to be conducted by the Department of Defense.

Jaques Vallée, a former contractor for the government's UFO office and the co-author of a book on the 1945 case, gave an exclusive interview to DailyMail.com about it.

Vallée, a renowned scientist and UFO investigator, was the inspiration for the French scientist character in Steven Spielberg's Close Encounters of the Third Kind, played by François Truffaut.

In his interview, he described the alleged August 1945 crash of an avocado-shaped 'craft' on the edge of the atomic bomb testing site near San Antonio, New Mexico – about 100 miles from the infamous Roswell crash two years later. 

Jaques Vallée, a former contractor for the government's UFO office, gave an exclusive interview to DailyMail.com about the 1945 UFO crash 

The National Defense Authorization Act, which passed Congress this month, includes a section requiring the Department of Defense's All-domain Anomaly Resolution Office (AARO) to review and prepare a report on all previous government investigations of UFOs dating back to 1945.

The bill's text previously only went back to 1947, but a late amendment changed it to '45.

'I was not involved in the drafting of the legislation, but several of my DC friends were, and they got the date of the investigation pushed back to 1945,' Vallée told DailyMail.com.

'Several of the Congressmen involved have the book that Paola Harris and I wrote about our research at [the alleged crash site called] Trinity.'

Vallée and Italian UFO journalist Harris's 2021 book, Trinity: the Best-Kept Secret, was re-released this year with new information, and is mainly based around testimony of three witnesses: a B-52 bomber pilot, and two young sons of a rancher on whose land the UFO supposedly crashed.

An artist's impression of the crash site and UFO is pictured.  'There was a gouge in the earth as long as a football field, and a circular object at the end of it… It was the color of the old pot my mother was always trying to shine up, a dull metallic color,' one witness said

The two researchers interviewed the family of Lt. Col William Brothy, who said he revealed in the years after the incident that he was sent out to survey the crash site on August 16, 1945.

'The first witness was a bomber pilot who was coming in for landing at Alamogordo [the neighboring airbase],' Vallée told DailyMail.com. 'He was asked by the controllers to look at a communication tower that had lost signal.

'He told the story to his family. His son gave us the recollection of what his father had described.

'Flying over, he saw the tower was bent, as if it had been hit by something very hard. And then he saw in the vegetation some distance away a large egg-shaped object. And there were two little kids that he called little Indians, on their horses next to the object.'

Vallée says those two kids were Jose Padilla, 9, and Reme Baca, 7. 

Padilla, now 86, became a Highway Patrol officer for 32 years, and Baca, who died in 2013, became a US Marine and later a senior staffer for Washington Governor Dixy Lee Ray.

They kept their story secret for more than 50 years, at last deciding to come forward in 2003 in an interview with a journalist from their hometown.

Interviews with Vallée and Harris decades after the crash saw them describe stumbling across the wreckage of a craft while looking for a lost cow on Padilla's father's ranch by the Rio Grande on August 16, 1945.

'We heard this sound and the ground shook,' Baca said in one interview. 'We saw smoke coming from maybe a couple of canyons down... We worked our way down the ridge.

'There was a gouge in the earth as long as a football field, and a circular object at the end of it… It was the color of the old pot my mother was always trying to shine up, a dull metallic color.'

He said he could feel the heat from the crash 'through the soles of your shoes'. Baca said he picked up a piece of foil-like metal that sprung back to its original shape when folded.

Reme Baca was seven at the time. He died in 2013. He was a Marine and later a senior staffer for Washington Governor Dixy Lee Ray

'Strange-looking creatures were moving around inside,' he added. 'They looked under stress. They moved fast, as if they were able to will themselves from one position to another in an instant. They were shadowy and expressionless, but definitely living beings.

'They had big bulgy eyes. Four foot tall, and they were real thin, needle-thin arms… Their heads looked like a campamocha [praying mantis].

'They seemed like us – children, not dangerous. But we were scared and exhausted.

The boys fled home on their horses and told Padilla's father what they had seen. Faustino Padillo told them it probably belonged to the Army and to ignore it. But they persuaded him to check out the site two days later with state policeman Eddie Apodaca.

Baca and Padillo said the 'craft' was still there, but the debris was gone, the object covered with dirt, and the ground appeared to have been raked.

The next day an Army sergeant named Avila, showed up at the ranch, asking Faustino if they could cut out his fence, put in a gate and grade a road to the crash site for a tractor-trailer, Baca said.

'We have one of our experimental weather balloons that inadvertently fell on your property,' Baca remembered the sergeant saying.

The crash was on the edge of the atomic bomb testing site near San Antonio, New Mexico – about 100 miles from the infamous Roswell crash two years later

In 2015 Vallée had a spectroscopy analysis performed on the metal panel they said they recovered from the wreckage. It points to a mundane, man-made origin. The samples are pictured 

Over the following week, the two boys snuck out to the site and used binoculars to spy on a unit of Army officers who stood guard, loaded the 25 by 14 foot, roughly five ton 'avocado-shaped' object onto a flatbed truck, and covered it with blue tarpaulins, they told Harris.

Vallée was the inspiration for the scientist character in Spielberg's Close Encounters of the Third Kind

There was no sign of the creatures they claimed they saw earlier.

On the last day, the boys plucked up the courage to sneak up and peek under the tarp while the young, bored soldiers were at lunch.

'Jose said, "I think they're going to take it tonight." I said, "Yeah, how about a souvenir?"' Baca told Harris.

'Jose pulls part of the tarp off, exposing the gash on the side of the craft, while I hold the tarp open. Jose climbs into the gash.'

They described 'ridges' inside every few feet, 'silvery colored strands' like angel hair decorations, and a 2.5ft metal panel attached to the rear wall with pins.

'No seats or anything,' Baca said. 'It must have been cleaned out, or maybe there weren't any. Couldn't see any instruments, like gauges, clocks, steering wheel, brake pedals, nothing like that.'

The plucky kids grabbed a crowbar from the tractor, used it to rip the large panel off the wall, and scurried off.

They said they hid the metal under the floorboards of a nearby building, and kept quiet about the case, fearing retribution by the Army against their families – especially after officers came to search Faustino's house.

Baca and Padilla eventually moved away and lost contact until 2002, when Baca reconnected with his old friend via a genealogy search. It was then they decided to tell their story.

In 2015, Vallée had a spectroscopy analysis performed on the metal panel they said they recovered from the wreckage. It points to a mundane, man-made origin.

The metal is 'aluminum primarily alloyed to copper and silicon' the report by Frontier Analysis said, a mix often used for 'engine crankcases, gas and oil tanks, engine oil pans, typewriter frames, and engine parts.' The isotopic ratios for the metals in the panel are within the range found on Earth.

The foil-like metal that Baca claimed he picked up has been lost – after he allegedly used it to fix a leaking pipe on the ranch as a boy.

While other researchers have abandoned the case due to the lack of results and paper trail, Vallée says it did not diminish the mystery for him.

'We have yet to ask what an ordinary, human fragment of some low-tech aluminum gadget was doing aboard a fantastic craft dropping from the sky in the middle of a storm, shattering the Marconi Tower of the White Sands Missile Range as its crew of diminutive insectoids skidded weirdly through the cabin,' he wrote in his book.

'You can't nail an aluminum bracket to the interior wall of a weather balloon, no matter how sophisticated. Every nine-year-old kid in New Mexico knows that.'

Vallée, who worked as a contractor for a previous reincarnation of the government's UFO office, the Advanced Aerospace Weapon System Applications Program, told DailyMail.com he is hopeful that a review of the Trinity alleged crash by the new UFO office will turn up further evidence.

'It will re-open the research on a more historically accurate and significant time scale,' he said.

And the data scientist believes he knows where AARO investigators should go looking: the Department of Energy.

'Reme Baca assisted Dixy Lee Ray in winning the election as governor of Washington in 1976. She had been chair of the Atomic Energy Commission [1973 to 1975],' he said.

'She showed Reme when he was helping her in the campaign, a record of the recovery of the craft. It was secret, she did not leave it with him. But she indicated that there was a record in the files of the Atomic Energy Commission.'

Intriguingly, the new defense budget legislation signed into law last week also includes a whistleblower program for reporting 'deep black' UFO programs to Congress.

In May, the House Intelligence Committee held its first public hearing on UFOs in 54 years where panel members grilled Deputy Director of Naval Intelligence Scott Bray (left) and Undersecretary of Defense for Intelligence and Security Ronald Moultrie (right)

An amendment to the 2023 National Defense Authorization Act (NDAA) gives protections to any whistleblowers coming forward to congress in classified briefings to disclose any previously hidden programs on 'unidentified anomalous phenomena' involving 'material retrieval, material analysis' and even 'reverse engineering' and 'developmental or operational testing'.

Former UFO office director Lue Elizondo told DailyMail.com: 'This language is truly revolutionary in terms of ensuring the American people can finally get to the bottom of a decades-old mystery.'

Former Deputy Assistant Secretary of Defense for Intelligence, Christopher Mellon, added that the new laws mean AARO is no longer a 'toothless organization, and now has 'personnel, authority, resources and strong support from Congress.'

Another NDAA amendment requires the UFO office to compile 'a written report detailing the historical record of the United States Government relating to unidentified anomalous phenomena' going back to January 1 1945.

The review will include 'successful or unsuccessful efforts to identify and track unidentified anomalous phenomena', and 'any efforts to obfuscate, manipulate public opinion, hide, or otherwise provide incorrect unclassified or classified information.'

South Koreans report UFO sighting as defence ministry secretly launches rocket

Edited By Saurav Mukherjee

Though the South Korean defence ministry had kept the launch a secret, they explained that they'd been test-firing a solid-fuelled rocket, The Mirror reported.

Stating that the the rocket was part of the military's efforts to build a space-based surveillance capability, the South Korean defence ministry said that it was aimed to bolster its defences.

The ministry added that it did not notify the public of the launch in advance as it involved sensitive military security issues, the report said.

Across the country, the police and emergency offices received hundreds of reports of witnessing of a suspicious flying object and mysterious lights.

The new rocket test comes four days after South Korea accused North Korea of flying five drones across the border for the first time in five years.

Amid the escalation by South Korea and the West, the North Korea conducted a record number of missile tests this year.

Meanwhile, North Korea test-fired three short-range ballistic missiles toward the Sea of Japan on Saturday, South Korea's Yonhap news agency reported. The missiles were launched from Chunghwa County in North Korea's North Hwanghae Province, Yonhap said, citing the South Korean Joint Chiefs of Staff (JCS), reported Hindustan Times.

Curiosity rover discovers water-rich fracture halos in Gale Crater

by Arizona State University

A research team using new methods to analyze data from NASA's Curiosity rover and its neutron spectrometer Dynamic Albedo of Neutrons, or DAN, on Mars was able to independently verify that fracture halos contained water-rich opal, potentially serving as an important resource for human exploration.

The study finds that the vast subsurface fracture networks would have provided water-rich and radiation-shielded conditions that were potentially more habitable than those on the surface.

In 2012, NASA sent the Curiosity rover to Mars to explore Gale Crater, a large impact basin with a massive, layered mountain in the middle. As Curiosity has traversed along the Mars surface, researchers have discovered light-toned rocks surrounding fractures that criss-cross certain parts of the Martian landscape, sometimes extending out far into the horizon of rover imagery. Recent work finds that these widespread halo networks served as one of the last, if not the last, water-rich environments in a modern era of Gale Crater. This water-rich environment in the subsurface would have also provided more habitable conditions when conditions on the surface were likely much more harsh.

As part of a new study published in the Journal of Geophysical Research: Planets, led by former Arizona State University NewSpace Postdoctoral Fellow Travis Gabriel, now a research physicist for the U.S. government, archival data from several instruments were examined and showed considerable anomalies near light-toned rocks earlier in the traverse. By happenstance, Curiosity rover drove right over one of these fracture halos many years ago, long before Gabriel and ASU graduate student and co-author Sean Czarnecki joined the rover team.

Looking at the old images, they saw a huge expanse of fracture halos extending far into the distance. By applying new methods for analyzing instrument data, the research team found something curious. These halos not only looked like halos found much later in the mission, in completely different rock units, but were similar in their composition: a whole lot of silica and water.

"Our new analysis of archival data showed striking similarity between all of the fracture halos we've observed much later in the mission," Gabriel said. "Seeing that these fracture networks were so widespread and likely chock-full of opal was incredible."

Gabriel and his team of researchers studied the composition of light-colored rocks surrounding the fractures on the ground, or fracture halos, in Gale Crater. Previous studies Gabriel was involved in used the rover's laser-induced breakdown spectrometer, Chemistry and Camera, or ChemCam, to show that these halos may be composed of opal, a material that has important implications for the history of Gale Crater. Opal itself contains a large amount of water, which produced a strong signal in another instrument on the rover: the DAN spectrometer.

Observing drill cores taken at the Buckskin and Greenhorn drill sites many years into the mission, scientists confirmed that these light-toned rocks were very unique compared to anything the team had seen before.

"These light-toned rocks were lighting up in our neutron detector, producing anomalously high thermal neutron count rates," Gabriel said.

In addition to looking back through archival data, Gabriel and his team went searching for opportunities to study these light-toned rocks again. Once they arrived at the Lubango drill site, a bright-toned fracture halo, Gabriel led a dedicated measurement campaign using the neutron spectrometer, confirming the opal-rich composition of fracture halos.

The discovery of opal is noteworthy as it can form in scenarios where silica is in solution with water, a similar process to dissolving sugar or salt in water. If there is too much salt, or conditions change, it begins to settle at the bottom. On Earth, silica falls out of solution in places like lake and ocean bottoms and can form in hot springs and geysers, somewhat similar to the environments at Yellowstone National Park.

Water-rich environments in the subsurface of Mars could have provided a safe haven from the harsh conditions on Mars' surface, which is rather inhospitable compared to Earth. In Gale Crater, temperatures can go below minus 100 degrees Fahrenheit in the winter night time, reaching only up to roughly 30 degrees Fahrenheit in the warmest of afternoons. Gale crater also experiences far more radiation than the surface of Earth due to our much thicker atmosphere. Every day spent in Gale crater would expose you to a cosmic-source radiation dose that roughly equates to a daily pelvis X-ray.

Since scientists expect that this opal in Gale Crater was formed in a modern Mars era, these subsurface networks of fractures could have been far more habitable than the harsh modern-day conditions at the surface.

"Given the widespread fracture networks discovered in Gale Crater, it's reasonable to expect that these potentially habitable subsurface conditions extended to many other regions of Gale Crater as well, and perhaps in other regions of Mars," Gabriel said. "These environments would have formed long after the ancient lakes in Gale Crater dried up."

The significance of finding opal on Mars will have advantages for future astronauts, and exploration efforts could take advantage of these widespread water resources. Opal itself is made up of predominantly two components: silica and water, with minor amounts of impurities such as iron. Since opal is not a mineral, the water is not bound as tightly within a crystal structure. This means that if you grind it down and apply heat, the opal releases its water. In a previous study, Gabriel and other Curiosity rover scientists demonstrated this exact process.

Although Gabriel and his team aren't able to perform an exhaustive assessment of the water content in all halos, the dedicated neutron experiments they performed over two of these halos demonstrate that a single-meter halo could house roughly one to 1.5 gallons of water in the top foot of the surface.

New Martian water resource: Opal?

What does this research finding mean for future Mars exploration? The poles of Mars house a large amount of water ice among other volatiles like carbon dioxide. In the present day, the equator of Mars by comparison is water poor, showing no sign of widespread water ice resources in the near surface. The study suggests that water-rich opal may be lining many landscapes across regions of Mars where scientists otherwise don't expect water.

Surprisingly, the opal in Gale Crater retains water despite the dry conditions of the modern-day atmosphere. Combined with growing evidence from satellite data that shows the presence of opal elsewhere on Mars, these resilient materials may be a great resource for future exploration activities elsewhere on Mars—that is, if opal elsewhere on Mars also retains water to the same degree as the opal in Gale Crater.

Opal forms in water-rich environments; however, it was found in fractures that formed much later in geologic time compared to the majority of rocks in Gale Crater. Much of Gale Crater's rocks were formed in an ancient lake environment. This demonstrates that the water that formed the halos was around in the subsurface much later and that it was much more widespread than researchers thought.

Once opal forms, it tends to mature into a more crystalline form when exposed to water and fluctuating conditions. The fact that this opal was so well preserved suggests that once it was formed, there wasn't much interaction with water thereafter. In these ways, discoveries from the Curiosity rover help us understand the where, when and what about water on Mars.

"It's amazing to see Curiosity's neutron detector, the rover's only subsurface probe, which was originally only expected to survive for a few years into the mission, still providing fantastic results like these that reveal the nature of water and hydrated materials buried just below the Martian surface," said Craig Hardgrove, co-author of the work, associate professor at ASU's School of Earth and Space Exploration and scientist on Mars Science Laboratory Curiosity rover's DAN team.

What's next?

Gabriel and the team continue to investigate the role of water in the formation and alteration of Martian rocks as the Curiosity rover heads up the central mound of Gale Crater, but no such luck has been made in discovering new halos at recent elevations. As a member of NASA's latest rover team, Mars 2020 Perseverance rover, Gabriel is eager to explore silica-rich features in a new location on Mars to understand the nature of water-rich environments elsewhere on the red planet.

For some people going to this planet would allow to study closely these celestial objects made of rocks and metals. For others, Mars could be the fallback planet, if we could no longer live on Earth. Myth for some, challenges for others, making a colony on Mars to make it habitable, the questions have not stopped talking. But our close cousin was not always an arid world, at the mercy of the solar wind. There was a time when water covered much of the Martian surface and potential life could have developed there...

Keep your eyes to the skies this month! Stargazers will have a once-in-a-generation chance to see a new comet at the end of January, NASA reveals

• New comet discovered in March 2022 can be spotted from Earth later this month
• Skywatchers will be able to see Comet C/2022 E3 (ZTF) in January and February
• On February 2 it'll be at nearest position to Earth — some 26.4 million miles away
• It could be the first comet that is visible to the naked eye since NEOWISE in 2020

By SAM TONKIN FOR MAILONLINE

It's not often that stargazers get the opportunity to spot a comet with the naked eye.

But at the end of this month – or possibly the start of February – a newly-discovered space rock will whizz by our planet and light up the night sky.

C/2022 E3 (ZTF) was discovered in March last year while inside Jupiter's orbit, and will make its closest approach to the sun on January 12 and Earth on February 2.

Comets are notoriously unpredictable, but if this one continues its current trend in brightness it should be easy to spot with binoculars or a telescope.

Look up this month! C/2022 E3 (ZTF), which was discovered in March last year while inside Jupiter's orbit, will make its closest approach to the sun on January 12 and Earth on February 2 

KEY FACTS: COMET C/2022 E3

Better still, it may even be visible to the naked eye if skies are dark towards the end of the month.

If that is the case it will be the first comet that can be seen with the unaided eye since NEOWISE raced past Earth in 2020, although it won't be anywhere near as spectacular.

NEOWISE left a long, misty tail, while E3 is likely to appear as a grey streak or smudge in the night sky.

However, neither match the brightness of Hale-Bopp, which was widely seen in 1997.

Astronomers don't expect Comet C/2022 E3 to visit Earth again for at least another 50,000 years, having last been visible during the Ice Age.

In terms of passing our planet, it won't be in any way close. In fact, the nearest it will come to Earth is 26.4 million miles (42.5 million kilometres) on February 2.

Observers in the Northern Hemisphere will find the comet in the morning sky, as it moves swiftly from the northeast to northwest and passes between the Little and Big Dippers during January.

'This comet isn't expected to be quite the spectacle that Comet NEOWISE was back in 2020,' Preston Dyches from NASA's Jet Propulsion Laboratory, said in a video shared by the US space agency.

'But it's still an awesome opportunity to make a personal connection with an icy visitor from the distant outer solar system.' 

Stargazers in the Southern Hemisphere will have to wait a little longer to catch a glimpse, however, as Comet C/2022 E3 won't be visible for them until early February.

In March 2022, astronomers discovered the new space rock using the wide-field survey camera at the Zwicky Transient Facility in California.

Since then, the new long-period comet has brightened substantially and is now sweeping across the northern constellation Corona Borealis in predawn skies. 

At the end of last year, scientists snapped the first detailed photo revealing the new Comet C/2022 E3's brighter greenish coma and a yellowy dust tail. 

Comets are made of ice, gas and rock – often described as giant space icebergs – that tend to originate in the outer solar system and move in on a long orbit.

The other major type of space rock, called asteroids, tend to be made of metal or rock and can come from anywhere in the solar system — including a large grouping of asteroids situated between Mars and Jupiter.

Comet Neowise was first spotted by — and named after — NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) space telescope in March 2020.

The icy body then became visible from the Earth's surface from the northern hemisphere for a short while in the summer of that year as its proximity to the sun caused it to melt, unleashing tails of dust and gas behind it.

During its closest approach on July 23, 2020, it was still 64 million miles from the planet. 

It then headed back out to space at around 144,000 miles per hour and will not to return for some 7,000 years.

Has Russia’s War Doomed The International Space Station?

Russia Cosmonauts finally realized why SpaceX Dragon is better than Soyuz after DAMAGED

The 2022 Space race ended with huge successes for the US and China. The most impressive name is definitely Elon Musk's SpaceX. With 61 flights, SpaceX tied a record set by the Soviet R-7 rocket, which in 1980 flew a combined 61 missions across its Soyuz, Molniya, and Vostok variants.

And for every winner, there must be a loser!
Russia clearly had a terrible year in space. The country only launched 22 times.
More seriously, its best spacecraft- Soyuz has been stuck on ISS for weeks.
In an attempt to potentially secure an alternate lifeboat for two Russian cosmonauts and one NASA astronaut, NASA and Russian space agency Roscosmos are conducting a review of available options, which included inquiring with SpaceX about using one of its Dragon capsules as a replacement for Soyuz MS-22.
This is definitely the time Russia's cosmonauts realized SpaceX Dragon is better than Soyuz after damage.
Find out everything about this in today's episode of Alpha Tech:

On Dec. 15, 2022, the Soyuz spacecraft MS-22 suffered a significant coolant leak while docked at the ISS just prior to a planned Russian spacewalk. While the leaky Soyuz poses no immediate danger to the space station or its crew, it remains unknown if the Soyuz craft is flightworthy; as such, the MS-22 crew no longer has a viable lifeboat in the event of an emergency.

As the result, NASA inquired about using a SpaceX Dragon capsule to bring astronauts home from the ISS following a recent leak aboard a Russian Soyuz capsule, a NASA blog post has stated.

A previous report published by Reuters stated the same, but NASA's blog post confirms that the agency is, in fact, mulling using a SpaceX Dragon spacecraft as an ISS lifeboat.

Another option is for Roscosmos to send a replacement Soyuz craft. But the earliest such a mission could launch would be February, according to statements made by Sergei Krikalev, head of the Yuri Gagarin Cosmonaut Training Center near Moscow.

Roscosmos is still investigating the cause of the leak and plans to issue its findings this month.

Low flying orbs and light entities swimming in the air

Spotted a glowing orb flying much lower than usual, as I approached and filmed it traversed the air and there is other activity going on, when I panned back to the initial position another one of the orbs ascended and blinked intermittently. Lastly towards the end I noticed some type of luminous entity flew in front of my cellphone camera, quite close to me, in a swimming fashion.

Aliens or Ancient Humans? Top 10 Alien Encounters (2022)

Aliens or Ancient Humans? Top 10 Alien Encounters (2022). UFOs became a modern sensation after the media reported US businessman Kenneth Arnold as having witnessed “flying saucers” on June 24, 1947. Since then, a flood of similar stories followed from around the world. It is the same with all the other UFO stories from around the world, they were mysteries without any substantial evidence. But with the advancement of technology, multiple UFO sightings around the world have been captured on camera.

It’s winter here on Earth, for those living in the northern hemisphere. This means snow, rain, colder temperatures, and all the other things we associate with “the festive season.” Much the same is true for Mars (aka. “Earth’s Twin”), which is also experiencing winter in its northern hemisphere right now. This means colder temperatures, especially around the polar regions where it can get as low as -123 °C (-190 °F), as well as ice, snow, frost, and the expansion of the polar ice caps – which are composed of both water ice and frozen carbon dioxide (“dry ice”).

While Mars does not experience snowfall the same way Earth does, seasonal change results in some very interesting phenomena. Thanks to the many robotic explorers NASA and other space agencies have sent to Mars in the past fifty years, scientists have been able to get a close-up look at these phenomena. These include the Viking orbiters and landers that studied the planet in the 1970s (with groundbreaking results) to the Mars Reconnaissance Orbiter (MRO), the Mars Exploration Rovers (Spirit and Opportunity), and the Curiosity and Perseverance rovers exploring the surface today.

Thanks to these dedicated orbiters, landers, and rovers, scientists have learned a few salient facts about snow on Mars: it comes in two varieties (water ice and dry ice), and it only ever snows in the coldest regions and times – at the poles, under cloud cover, and at night. Because Mars’ atmosphere is so thin and its temperatures so extreme, water and carbon dioxide do not freeze but sublimate, transforming from a gas directly to ice (and back again). On top of that, dry ice snowflakes are cubic, meaning they have four sides instead of the familiar six-sided configuration we are familiar with.

As with water molecules, this is because a crystal’s shape depends on how atoms arrange themselves. In the case of CO2, molecules always bond in groups of four. Moreover, snow never reaches the ground on Mars but sublimates as it falls from the clouds to the surface. Since most orbiters cannot see through these clouds, and rovers cannot withstand the extreme cold, no images of falling snow have ever been taken. But scientists know that Mars experiences snowfall, thanks to a handful of dedicated instruments.

These include the Mars Climate Sounder (MCS) aboard the MRO, which observes the Martian atmosphere in visible and infrared light to measure the temperature, humidity, and dust content of the Martian atmosphere. This allows science teams to peer through cloud cover and detect CO₂ snow falling to the ground. Sylvain Piqueux, a planetary research Scientist at NASA’s Jet Propulsion Laboratory, explained the intricacies of Martian snow in a recent interview with NASA’s Mars News Report (a series dedicated to educating the public on the exploration and study of the Red Planet). As he explained:

“Enough falls that you could snowshoe across it. If you were looking for skiing, though, you’d have to go into a crater or cliffside, where snow could build up on a sloped surface. Because carbon dioxide ice has a symmetry of four, we know dry-ice snowflakes would be cube-shaped. Thanks to the Mars Climate Sounder, we can tell these snowflakes would be smaller than the width of a human hair.”

In addition, NASA’s Phoenix mission landed within 1,000 miles (about 1,600 kilometers) of Mars’ north pole in 2008. As part of its science operations, the lander used a laser-based atmospheric sensor – part of a special meteorological station provided by the Canadian Space Agency (CSA) – to detect water ice snow falling to the surface. The Viking landers also detected water frost at their landing sites, and NASA’s Odyssey orbiter observed frost forming and sublimating at sunrise many times during its mission.

When the CO₂ ice sublimates near the end of winter, the most iconic surface features on Mars result. This includes the strange and beautiful shapes that scientists have nicknamed “spiders,” “Dalmatian spots,” “fried eggs,” and “Swiss cheese.” The “spring thaw” also causes geysers to erupt as sunlight passes through layers of translucent ice, heating the gas pockets beneath it. This triggers eruptions that send dust onto the surface, creating a feature known as “Spring Fans” that scientists are studying to learn more about which direction the Martian winds are blowing.

As Piqueux explained, all of this data will be vital when it comes time to send crewed missions to Mars, which NASA hopes to do by the 2030s:

“[T]he Pheonix lander, the NASA mission that arrived on Mars in 2008, observed beautiful frost landscapes that formed around it. The Pheonix lander was also able to scratch the surface and, for the first time, see this water ice just below the ground. This is the kind of water ice that astronauts could potentially use in the future when we go there.”

Many fascinating things accompany seasonal changes on Mars, and we are fortunate to bear witness to these things thanks to many generations of robotic missions. Soon enough, astronauts will witness Mars and its dynamic climate firsthand, and their research will fuel scientific breakthroughs and discoveries for generations to come!

“This is particularly important because it is thought that Mars used to have a thicker atmosphere in the past, perhaps sustaining Earth-like surface conditions,” Dr. Mathieu Lapôtre, who is an assistant professor of geological sciences in the Stanford Doerr School of Sustainability and a co-author on the study, said in a statement. “However, it lost most of it, and we don’t really know when, how fast, and why.”

This study came about after scientists were puzzled over images from NASA’s Curiosity Mars rover in 2015 that observed similar windblown patterns on Mars’ surface. These include giant sand dunes along with smaller formations like the impact ripples seen on Earth but also formations about 10 times as big as these ripples, but smaller in size compared to sand dunes. Essentially, Curiosity observed a type of middle-sized sand formation never seen.  

One proposed hypothesis for these middle-sized sand formations could be from the ongoing growth of impact ripples due to the low Martian atmospheric pressure. Dr. Lapôtre and other scientists have previously suggested that these formations could result from what’s known as hydrodynamic (fluid motion) instability, which can be used for both liquid and air movements.

For the study, the researchers used AI and more than 130,000 high-resolution images of Mars to perform a quantitative analysis on one million barchan dunes, also known as crescentic dunes, on Mars to examine how their sizes and shapes vary across the Martian surface. Barchan dunes are common on both Earth and Mars and have been imaged extensively on the Red Planet by the HiRISE camera onboard NASA’s Mars Reconnaissance Orbiter.

Their findings indicate that these middle-sized sand formations are not impact ripples, but instead are like miniature sand dunes whose growth ceases at a certain point due to the predicted change in the fluid-like airflow in the low atmospheric pressure close to the Martian surface.

The Dark Dunes of Mars

“Impact ripples form on Mars exactly like they do on Earth, and have more or less the same size,” Dr. Lior Rubanenko, who is the lead author of the study while conducting the research as a postdoctoral scholar in geological sciences at Stanford, said in a statement. “This makes sense, since the mechanism that forms impact ripples has less to do with the properties of the atmosphere and more with the mechanics of sand transport.”

“Now that we know how the size of these ripples varies with atmospheric density and why, we can use the size of fossilized ripples in very old rocks to reconstruct the history of Mars’ atmosphere,” Dr. Lapôtre said.

As always, keep doing science & keep looking up!

Mysterious UFO spotted over Tamaulipas highway, Mexico

An unidentified flying object (UFO) was spotted on a highway in Tamaulipas, Mexico, according to a photograph shared on a forum dedicated to UFO sightings. The image, which shows two spherical objects flying over a stretch of land, was taken on December 29 by a user named Juanito Juan. “For the envious who do not believe … 12:05 pm … on the side of the road, Valle Hermoso to Matamoros, Tamaulipas … I thought it was one and not … there are 2,” Juanito Juan wrote in the Facebook forum “Ufo-Ovnis-Paranormal”.

Juanito Juan also claimed to have captured an image of a single round object in the skies over Tamaulipas on December 28 and another fast-moving, unknown phenomenon on December 18. “There is no doubt that something is happening in the sky of our city,” Juanito Juan said.

The UFO sightings have generated interest among social media users, with some speculating about the nature of the objects and others suggesting that the images may have been altered. “I had to see a similar large bright one that was static for 5 minutes, I was on the road when I wanted to take the phone out to take a photo, it disappeared, it was the same but brighter,” said user Ezequiel HC.

User Jorge Alejandro added: “I saw one of those in Reynosa, Tamaulipas one night that was on the roof of the house, when I saw it it went at an impressive speed and after about 10 minutes it came back and accelerated again.”

It remains unclear whether the UFO spotted on the Tamaulipas highway was of extraterrestrial origin or had a more mundane explanation. However, the sightings have certainly generated excitement and speculation among those who have seen the images.

Nieuwe studie suggereert dat aliens nog geen contact met onze aarde hebben gezocht omdat die “niet interessant genoeg is”

Aliens: bestaan ze nu echt en zullen ze ooit naar onze aarde afzakken? Volgens een nieuwe studie is het antwoord op die laatste vraag alvast teleurstellend. Het onderzoek belicht de ‘Fermi-paradox’. Die stelt dat buitenaardse wezens gezien de leeftijd van het heelal hoogstwaarschijnlijk al langeafstandsruimtevaart hebben ontwikkeld en onze aarde dus al lang bezocht zouden moeten hebben. Maar waarom kiezen ze er dan toch voor om weg te blijven? “We zijn op aarde gewoon niet interessant genoeg”, luidt het onderzoek.

Bron: Live Science, Space.com

In de studie, die gepubliceerd werd op het wetenschappelijke platform ‘arXiv’, beweren onderzoekers dat buitenaardse wezens enkel geïnteresseerd zijn in de meest technologisch geavanceerde planeten. Onze aarde hoort daar jammer genoeg niet bij. De mensheid mag dan wel biologisch ver geëvolueerd zijn, onze technologie staat daarentegen nog niet op punt, benadrukt Amri Wandel, hoofdonderzoeker en astrofysicus aan de Hebreeuwse Universiteit van Jeruzalem.

“Aliens hebben onze signalen nog niet ontvangen”

Wij sturen op aarde nog maar sinds de jaren 30 signalen in de vorm van radiogolven uit die vanuit de ruimte kunnen worden opgevangen. Buitenaardse wezens hebben dus nog niet de kans gehad om de boodschappen te ontvangen, laat staan om erop te reageren. De signalen hebben tot nu toe naar schatting 15.000 sterren en hun omringende planeten bereikt, maar dat is slechts een fractie van de 400 miljard sterren in de Melkweg. Alleen sterren binnen een straal van 50 lichtjaar (één lichtjaar is ongeveer 9,5 biljoen kilometer, red.) hebben met andere woorden al de tijd gehad om een signaal terug te sturen, legt Wandel uit.

De studie suggereert dus dat er zich binnen 50 lichtjaar van onze planeet geen intelligente beschavingen bevinden. Maar verder in de ruimte kan dat uiteraard wel het geval zijn, klinkt het.

Bovendien werden de allereerste radiosignalen niet doelbewust de kosmos ingestuurd, waardoor ze allemaal door elkaar zouden zijn gelopen zodra ze de ruimte bereikten. Daarom konden aliens ze niet van elkaar onderscheiden. Pas in 1974 werd vanuit Puerto Rico bewust geprobeerd om in contact te komen met buitenaards leven. Met de Arecibo-telescoop werd toen de allereerste doelbewuste menselijke boodschap naar – hypothetische – aliens uitgezonden.

Nieuwe boodschap

Een groep internationale wetenschappers vindt dat het stilaan tijd is voor een nieuwe boodschap en heeft om die reden het ‘Beacon in the Galaxy’ (BITG)-project opgestart. De experten hebben reeds een boodschap voorgesteld die als doel heeft om een universeel middel voor de communicatie met buitenaardse wezens tot stand te brengen. De radioboodschap zal onder meer een diagram van het mannelijke en vrouwelijke lichaam bevatten.

Hoe meer signalen onze aarde uitstuurt, hoe groter de kans uiteraard is dat aliens er uiteindelijk naar zullen luisteren, besluit Wandel.

KIJK OOK.

Snel uitgelegd: is er intelligent buitenaards leven?

Ancient “Hieroglyphs” Discovered In Ukrainian Caves

A Ukrainian explorer followed his grandmother's clues and discovered a lost cave system in the middle of Kyiv. Professors are “amazed” that such a treasure was hidden in plain sight for thousands of years.

The cave system is located at Voznesenskyi Descent in Kyiv, Ukraine. Dmytro Perov, a conservationist at the Center for Urban Development in Kyiv reported on Radio Kultura that the caves were found beside a dismantled house that Kyiv housing authorities had deemed as unsafe for inhabitation.

A report in Suspline says that in August this year Perov learned that the Kyiv City Council were drawing up plans to develop this area. His attention was drawn to a particular house address: Voznesenskyi Uzviz, 25, in which his great-great-grandmother Daria Volosova used to live at the beginning of the 20th century, at which time it was a three-story family manor.

• Tracing the Paths of the Vikings Through Their Graffiti

An Amazing Lost Treasure

A report in Rubryka says Perov’s Grandmother used to speak about a big stone house next to an ancient cave, but no one knew where it was located. Perov told Radio Kultura that he had examined the area several times in the past and that only the front facia of the house remained, hidden in bushes.

The conservationist told reporters that he decided to team up with his friends to go to the old house “on a small expedition to look for caves” and they identified an entrance. Last Saturday, Perov and a team of researchers from the Institute of Archaeology conducted the first archaeological explorations in the Voznesensky Caves. And having spent 3 hours inspecting the cave, Timur Bobrovskyi, a professor of archaeology at the Sofia Kyivska reserve said he was “amazed that such a treasure was found in the center of Kyiv”.

Pottery And Hieroglyphs From Bygone Cultures

Perov says the team explored two of the four caves, because the other two are full of silt that needs to be cleared out prior to any exploration. In the northern part of the cave the team identified fragments of pottery from the Late Kyivan Rus’ era, which was a state in Eastern and Northern Europe from the late 9th to the mid-13th century.

Perov wrote on Facebook that the team scoured around 40 meters (131 ft) of caves including the lower cave complex, which he said is twice as long as the upper passage and it has a series of “radial branches.” However, the most significant discovery was, in Petrov’s words: “a set of Kyivan Rus hieroglyphs and Varangian symbols from the Early Rus period” when the region was under the control of Varangian rulers.

• Vikings in Byzantium: The Varangians and their Fearless Conquests

Engravings in the cave walls appear to be Kyivan Rus hieroglyphs and Varangian.

( Dmytro Perov )

Animistic Animals And A Chicken’s Foot

Dmytro Perov said that while more research is needed to confirm it, they suspect some of the carved symbols might date all the way back to the 5th to 6th centuries BC. He says “ animistic images of animals and graffiti” from the Varyaz period were also found on the walls including the rune Algiz ("chicken's foot"). This was an ancient Varangian charm, a symbol of protection and long life.

Between the 7th–6th centuries BC several Hellenic Greek colonies were founded on the northern coast of the Black Sea on the Crimean Peninsula and along the Sea of Azov. After a period of control by the Roman empire, during the 1st millennium BC, the steppe hinterland was occupied by the Cimmerians, Scythians, and Sarmatians who traded with the Greek/Roman colonies.

Viking Bloodlines And Trade Routes

The Kyivan state was founded by the Varangian, or Viking, Prince Rurik in the late 9th century. His descendants developed and controlled an international trade route to the west until the 13th century. According to Britannia the Kyivan state comprised East Slavic, Norse, and Finnic peoples, so it will perhaps be impossible to identify who left the carved symbols on the cave walls.

For several months the Kyiv City Council has been planning to transfer the land plot to a private developer. However, Perov said that until more data is gathered from the caves the issue of transfer of the plot for development has been removed from the agenda of the Kyiv City State Administration.

BEERDIERTJES KUNNEN DECENNIALANG ZONDER WATER OVERLEVEN EN ONDERZOEKERS DENKEN NU TE WETEN HOE ZE HET DOEN

Caroline Kraaijvanger

Zonder water ga je dood. Dat geldt voor vrijwel alle levensvormen op aarde, maar – dankzij een gaaf en voor beerdiertjes uniek eiwit – niet voor deze minuscule meercelligen.

Beerdiertjes zijn opzienbarende wezentjes; de amper 0,5 millimeter lange diertjes zijn tijdens ruimtereizen bestand gebleken tegen vacuüm en kosmische straling. En toen onderzoekers ze recent in een speciaal geweer stopten om ze af te vuren, konden de beerdiertjes dat ook gewoon navertellen. Ook extreme hitte en kou, een gebrek aan zuurstof of kiemdodende ultraviolette lampen doen de beerdiertjes weinig. Net als een langdurig tekort aan water; onderzoek heeft reeds uitgewezen dat beerdiertjes decennialang zonder water kunnen overleven.

Raadselachtig
Dat laatste is – net als veel van het voorgaande trouwens – tamelijk raadselachtig. Want op watergebrek volgt uitdroging en dat vinden levende cellen niet zo prettig; wanneer ze uitdrogen, verliezen ze hun vorm en storten uiteindelijk compleet ineen. Ze functioneren dan niet meer (goed) en kunnen uiteindelijk afsterven. En dat heeft vanzelfsprekend weer dramatische gevolgen voor het organisme waar ze deel van uitmaken.

Maar uitdrogende beerdiertjes hebben dus geen last van in elkaar zakkende en afstervende cellen. “Hoewel water essentieel is voor al het leven dat we kennen, kunnen sommige beerdiertjes mogelijk decennialang zonder water leven,” stelt onderzoeker Takekazu Kunieda.

CAHS-eiwitten
Kunieda en collega’s hebben nu achterhaald hoe de kleine beerdiertjes dat precies doen. En een heldenrol is daarbij weggelegd voor zogenoemde CAHS-eiwitten. “De truc zit ‘m in hoe hun cellen omgaan met de stress die het proces van uitdroging met zich meebrengt,” legt Kunieda uit. “Aangenomen wordt dat wanneer water een cel verlaat, er een soort eiwit moet zijn dat voorkomt dat de cel ineenklapt. Na het testen van verschillende eiwitten, hebben we ontdekt dat cytoplasmic-abundant heat soluble (CAHS) eiwitten – die alleen beerdiertjes bezitten – verantwoordelijk zijn voor het beschermen van de cel tegen uitdroging.”

Hoe werkt het?
Deze CAHS-eiwitten zitten dus in de cellen van het beerdiertje. En zodra ze ‘merken’ dat de cel die hen omringt, uitdroogt, komen ze in actie. De eiwitten vormen dan een netwerk van gelachtige filamenten die de uitdrogende cel als het ware stutten en er zo voor zorgen dat deze zijn vorm behoudt. Dat is een omkeerbaar proces. Want zodra de cellen van het beerdiertje weer vocht tot hun beschikking hebben, trekken de gelachtige filamenten zich langzaam weer terug.

Mensen
Het is een ingenieuze oplossing. En grappig genoeg werken deze eiwitten – waar dus alleen beerdiertjes over beschikken – ook in cellen van andere organismen. De onderzoekers trekken die conclusie nadat ze de eiwitten in het laboratorium toepasten in uitdrogende cellen van insecten en mensen. Tot hun verbazing zagen ze dat de eiwitten ook hier in actie kwamen en stuttende filamenten vormden.

Hier zie je hoe CAHS-eiwitten filamenten vormen in een uitdrogende menselijke cel.

Als het aan de onderzoekers ligt, is hun studie de opmaat naar meer. Zo hopen ze dat deze er uiteindelijk toe leidt dat wetenschappers – geïnspireerd door de beerdiertjes – nieuwe manieren gaan vinden om bijvoorbeeld celmaterialen en biomoleculen droog op te slaan. Zo kan de houdbaarheid van materialen die veel in het laboratorium gebruikt worden, maar bijvoorbeeld ook van medicijnen en misschien zelfs van complete organen (bestemd voor transplantatie) in de toekomst wellicht worden opgerekt.

Daarnaast zijn er nog veel meer eiwitten die de wetenschappers graag onder de loep zouden nemen om het beerdiertje en zijn opmerkelijke eigenschappen nader te doorgronden. Uiteindelijk hopen Kunieda en collega’s zelfs meer dan 300 eiwitten van het beerdiertje te onderzoeken en zo verscheidene andere ‘superkrachten’ van het mysterieuze meercellige organisme te ontrafelen en waar mogelijk natuurlijk vervolgens ook in andere settings toe te passen.
