A TOP scientist claims she was sacked by Nasa after raising concerns about alien life on Mars.
Catharine Conley, the agency's Planetary Protection Officer from 2006 to 2017, also fears SpaceX astronauts won't come home alive.

Conley first accused officials at the Jet Propulsion Lab (JPL) in California of failing to clean the Mars 2020 rover correctly before its launch.
Mars 2020 is Nasa's mission sent to search for samples of the Red Planet to bring home and test for evidence of past or current alien life.
The rover, Perseverance, is still crawling around the surface after landing in February 2021.
Its job is to obtain the samples which will then be collected by a future Mars Sample Return Mission.
But Conley feared any material eventually flown home could be contaminated - and the whole mission scuppered.
She claims she was suddenly removed from the position after speaking out - and suspects it was to silence her concerns.
Conley told The Sun: 'Nasa decided they didn't want to do the kind of work that I had been doing.
'They didn't want to continue with the kinds of implementation that they had been doing historically.
'That was not something I thought was a good idea, so they decided they needed someone else for the job.
"This was basic planetary protection as it had been done for the prior 50 years or so."

Conley, who now works as a researcher, added: 'The Mars 2020 rover was cleaned in a way that was not compatible with prior levels of cleanliness, in particular regarding the amount of contamination that was getting introduced into the samples that were being collected for return.
'I pointed out that having a 0.1% chance of contaminating any individual sample, when you have 40 samples in total, comes out to a 4 per cent chance of having Earth contamination in the samples you're looking at.
'That makes it fairly difficult to be confident that you can distinguish between Earth life and Mars life.
'That was not something that the people at headquarters management wanted to hear and they took the steps that they thought were appropriate.'

Conley claims she had been told of staff being careless when using gloves and protective equipment.
She also claimed to have been told of staff bringing equipment into assembly rooms that was not properly cleaned, along with an 'attitude of skepticism I encountered regularly at JPL'.
Nasa states on its website that Mars 2020 Perseverance Rover remains an active mission.
It landed in February 2021 as part of Nasa's Mars Sample Return (MSR) campaign.
In January the agency said it was hoping to announce plans for the returning of samples in the second half of 2026.
But that has been thrown into doubt following Donald Trump's proposed cuts to Nasa, with MSR a casualty.

China is preparing to press ahead with their own plans to return Mars samples.
It has scheduled the Tianwen-3 Mars mission for launch in 2028, collecting and bringing samples back by 2031.
But Conley still fears the same problem.
She said: 'The concerns are similar. I've been looking at some of the reports that have come out about the Chinese proposed missions, and they're saying all the right things to the extent that I can obtain information.
'But it is difficult to follow up on what they are actually saying they're doing.
'I certainly had experience within my duties at Nasa of engineers saying one thing and doing something else.
'So it's difficult to know. But if other space agencies are not doing anything more than Nasa did, then I would be surprised if their contamination levels are low enough that you could detect the Mars signal underneath the background from Earth.'
Despite the cuts, Trump has proposed no savings on Nasa's plans to send astronauts to Mars in the 2030s.
Nasa's mission to Mars
Nasa hopes to send astronauts to Mars as early as the 2030s.
The space company has been working to advance its technologies in a bid to send a human crew to the Red Planet.
It would take astronauts up to nine months to reach Mars - which even at its closest is 33.9 million miles away.
Astronauts could then spend up to 500 days on the planet's surface before returning to Earth - which would take another nine months.
The crew would spend their time on the planet collecting data and assessing the planetary alignment that would allow the spacecraft to land and depart from Mars on the same orbit.
Last year, the agency completed a year-long simulated mission that saw four crew members out in a replica habitat in Houston, Texas.
They logged 378 days in the 1,700-square-foot, 3D-printed habitat called Mars Dune Alpha.
But Conley fears that doing so without a sample return mission means a gaping hole in knowledge for what astronauts will encounter.
She also questions if astronauts will be allowed home if they fall sick.
Conley added: 'Not doing a robotic sample return means we don't have detailed information about what kinds of materials the astronauts are likely to encounter, and possibly bring back to Earth, which could be quite problematic if there is something hazardous in Mars regolith, even if it's not biological.

'A question that didn't get answered during Apollo and certainly hasn't been addressed since is: if astronauts get sick after contacting Mars and we can't figure out why, should they be allowed to return?
'The fundamental problem, from my perspective, is overconfidence in thinking that we already know everything we need to know about what could happen, when we don't."
Conley also warned of Elon Musk's plans to send a manned crew to Mars through his company, SpaceX.
She added: 'SpaceX say they're planning to launch humans to Mars, but I have serious doubts about whether anyone would be alive when the spacecraft gets there since SpaceX doesn't seem to be developing long-term life support systems along with their rockets.
'Musk has made numerous claims about when he'll land humans on Mars that are distinctly implausible, at least if he wants the humans to be alive when they get there.
'Nasa is much more likely to be careful about preserving astronaut health but, ironically, seems not similarly concerned about protecting the Earth from possible Mars contamination.'
The Sun has approached Nasa for a response to Conley's allegations.

Discovery at Earth's 'most dangerous glacier' sparks joy among climate skeptics
Scientists have made a startling discovery that may debunk global warming at Earth's 'most dangerous glacier,' sending climate change deniers into celebration. Based on a surprising photo taken by the International Space Station (ISS) in 2023, researchers from around the world have concluded that three glaciers in Asia 's Karakoram mountain range have been gaining ice and merging. The NASA image revealed that the Lolofond and Teram Shehr glaciers have been slowly merging with the Siachen glacier near the borders of India, Pakistan, China, and Afghanistan. The region has long been referred to as the world's most dangerous glacier range due to the ongoing conflict between India and Pakistan, with both nations positioning troops on their side of the glaciers since 1984. Long before the photo was revealed, scientists had called the unexplained ice gains the 'Karakoram anomaly,' since many climate studies have found that most glaciers worldwide are losing mass due to rising temperatures. However, this is the second major glacier location to see more ice being formed in recent years. In May, researchers in Shanghai discovered that Antarctica started to reverse its decades-long trend of catastrophic melting and has seen record amounts of ice forming since 2021. The latest development from Karakoram has set off climate deniers on social media, who have continued to claim that the alarmism over global warming has been nothing more than a hoax. 'UH oh, Democrats. Are we back to a new Ice Age?' one person joked on X, referring to Democrat-led climate bills in Congress. 'This anomaly has baffled scientists for years, no doubt upsetting #ClimateChange fanatics,' another person posted. To the climate deniers' point, scientists studying the Karakoram anomaly since the 1990s still haven't been able to pin down a clear reason why more ice has been forming and the glaciers are merging. One possible explanation could be that favorable weather patterns in the region have kept the ice from melting. That includes seeing cooler summers and more snow in the winter. A 2022 study in the Journal of Climate found that wintertime precipitation intensity (snow) in the Karakoram range rose by roughly 10 percent between 1980 and 2019. However, a 2023 study in Earth System Science Data claimed that the phenomenon likely wouldn't last due to rising global temperatures countering this short stretch of cold weather. 'This may indicate a weakening of the abnormal behavior of glaciers in the Karakoram owing to the continuous warming,' the researchers said. Despite the latest climate findings, the region has continued to show signs of unusual ice growth that have left geologists and climatologists stumped. Another theory, posed by geology professor Kenneth Hewitt of Wilfrid Laurier University in Canada, suggested that thick layers of dust and debris could be keeping the ice underneath from melting in the sun like other glaciers. His 2005 paper in the journal Mountain Research and Development found that less than two inches of debris from local avalanches and rockfalls over the centuries would be enough to start protecting the ice from melting. However, researchers from the National Snow and Ice Data Center in Colorado shot this theory down, noting that if the Karakoram anomaly only started in the 1990s, as studies show, something else would need to spark this trend besides centuries of dust. Siachen has been the world's second-longest glacier outside of Greenland and Antarctica. NASA scientists have measured it to be around 47 miles long and 2.2 miles in width. Sitting near K2, the world's second-highest mountain, the Siachen glacier's peak starts around 19,000 feet above sea level and descends to around 11,800 feet. The photo released by NASA also highlighted the dark-colored moraines, which are parallel bands formed from rock and dust wedged between the glaciers as they merge. These layers were particularly noticeable around the Teram Shehr glacier as it smashes into the Siachen glacier from the right side. As scientists struggle to answer the question of why more ice is growing in this disputed part of Asia, the mystery has given skeptics of climate science even more evidence to use against so-called 'climate alarmists.' University of Cambridge professor Mike Hulme told in 2023 that climate alarmists have created tremendous distrust and ill will among the public by blaming almost all of society's issues on the climate emergency. 'Climate change is cited as the sole explanation for everything going wrong in the world. Drought, famine, flooding, wars, racism – you name it. And if it's bad, it's down to global warming caused by humans,' Professor Hulme said. 'I disagree with the doom-mongers. Climate change is not like a comet approaching Earth. There is no good scientific or historical evidence that it will lead to human extinction or the collapse of human civilization,' the professor of human geography added.

Asteroid the size of the Tower of Pisa to make close approach with Earth in days
If you've always wanted to see the Leaning Tower of Pisa, all you'll need to do is look up next week. An asteroid roughly the size of the famous Italian landmark is currently hurtling towards Earth at 46,908 miles per hour. The space rock, 2025 OW, will drift past our planet next Monday at a distance of 393,000 miles – about 1.6 times the distance to the Moon. Space officials estimate the rock is about 220 feet across, making it larger than the Leaning Tower of Pisa at 185 feet. 2025 OW is one of five 'planet-sized' asteroids getting up, close and personal with our planet over the next few days, Nasa says. The space agency's Asteroid Watch Dashboard says that 2025 OK1, which is estimated to be about 100 feet across, will fly past us today at a distance of 1,360,000 miles. Another airplane-sized asteroid, 2025-OZ, is also doing a drive-by visit of our home today. As you read this, it's about 3,340,000 miles away. On Saturday, two more giant asteroids will pass by Earth on Saturday: the 110-foot-wide 2025 OX will be 2,810,000 miles above your head. While 2025 OU1, about 140 feet across, will be slightly closer at 1,660,000 miles. But none of these rocks are anything to lose sleep over, astrophysicist, science journalist Alfredo Carpineti told Metro. 'There are over 13,000 near-Earth objects of comparative size that occasionally get near our planet,' the senior writer for IFLScience said. 'They could be dangerous if they hit Earth, but fortunately, these five will all fly well beyond the movement of the Moon.' Asteroids are lumps of rock, dust and metal left behind from the formation of our star system 4.6billion years ago. Most do laps around the Sun between Mars and Jupiter in the asteroid belt, some as small as rubble, and others hundreds of miles in diameter. Earth will be slammed by an asteroid about 300 feet once a decade, while one 10 times the size impacts us every 700,000 years. A space rock measuring just 160 feet in diameter can easily devastate the local area and pockmark the Earth, unleashing a force similar to a nuclear bomb – these happen once a millennium. The so-called 'city-killer' asteroid, 2024 YR4, which officials briefly feared had a 3.1% chance of colliding with Earth, is suspected to be 300 feet across. Our planetary defence options include intentionally smashing a satellite into it to nudge it off course or detonating a nuclear bomb near it. NASA's Jet Propulsion Laboratory in California and the Near-Earth Object Coordination Centre in Italy keep an eye on all these rocks whizzing about. They calculate the odds of an asteroid impact as they plot out the possible orbits, which get more accurate as they observe them more. More Trending This is exactly the case with 2025 OW, with scientists being able to predict its orbit for the next century. As of July, Nasa has discovered more than 38,600 near-Earth asteroids, of which 872 are larger than a kilometre. At least seven wandered close to Earth last month alone, with Nasa keeping an eye on 1,798 near-Earth objects on its 'risk list', though all have next to no chance of striking Earth. 'Still,' continued Carpineti, 'it's important we keep tracking them to know we will stay safe in the future.'

Life might have come from outer space, scientist say
The seeds of life on Earth might have come from outer space – and might be widespread throughout the rest of the universe, scientist say. Researchers have found complex organic molecules in a disc around a 'protostar' in a major breakthrough. Those molecules are seen as the precursors to the building blocks of life, which go on to become sugars and amino acids that are then combined into the complex flora and fauna that surrounds us. Researchers have found such complex organic molecules in other places before. But the new findings fill in a previously mysterious missing link – one that could suggest that life is more abundant than we realise. When cold protostar becomes a young star, surrounded by a disc of dust and gas, it is a violent process that includes intense radiation and the hurling out of gas. Researchers had been concerned that the extreme nature of that process could 'reset' the chemical compounds available around a star, meaning that they would have to be formed in the discs that at the same time are making planets. But the new findings suggest that complex molecules can stick around through that process, meaning they will be inherited by the discs that follow. The findings are reported in a new study, 'A deep search for Complex Organic Molecules toward the protoplanetary disk of V883 Ori', published in the The Astrophysical Journal Letters.
