Beware of what you “find” on Mars, scientists warn after the discovery of the fossils.

Imagem do rover da NASA em Marte à procura de fósseis de vida antiga

Mars remains a fertile field for otherworldly discoveries. There remains a strong belief that the planet has signs of Martian life that existed millions of years ago. However, researchers on the Red Planet looking for such signs of ancient life may be fooled by fossil specimens created by chemical processes.

These warnings open up a new front of doubt and uncertainty. Is the planet really just a handful of emptiness?

Rocks on Mars may contain several types of non-biological sediments, which look like the types of fossils that could be found if life ever existed on the planet, one study says.

The researchers say separating these false fossils from what may indicate ancient life on the surface of Mars that was temporarily inhabited four billion years ago is key to the success of current and future missions.

Mars may have structures similar to fossils

Astrobiological das Edinburgh Universities and Oxford are reviewing evidence for all known processes that could have created similar living sediments in the rocks of Mars.

As shown, they have identified dozens of processes - many of which are likely not yet discovered - that can create structures that mimic the simple microscopic life forms that may have existed on Mars.

Fossil Image Sample

Natural patterns that these processes can create are sediments that look like bacterial cells and carbon-based molecules that look like the building blocks of all known life forms.

In the past, we were deceived by the processes of imitation of life. In many cases, objects similar to fossil microbes have been described in ancient rocks on Earth and even in meteorites on Mars, but upon closer examination it turned out that they are of non-biological origin.

This article is a cautionary tale in which we call for further research into the processes of life imitation in the context of Mars, so as not to fall into the same traps over and over again.

Scientists say scientists will have to take a closer look at non-biological mineral deposits that look a lot like fossils, as in the case of the rover. Tenacity from the USA or Chang'e 5 from China.

At some point, the rover will almost certainly collide with something that looks a lot like a fossil, so being able to distinguish it from chemical structures and substances formed by chemical reactions is vital. For every type of fossil, there is at least one non-biological process that creates very similar things, so there is a real need to improve our understanding of how they are formed.

Explained by Sean McMahon, an astrobiologist at the University of Edinburgh.

Robots' eyes can be fooled by non-biological phenomena

Examples of such phenomena include physical processes associated with the destruction and deposition of sedimentary layers, which can lead to the formation of rocks with a strong visual resemblance to fossils.

"Fossils" can also be created in a "chemical garden," where the continuous mixing of chemicals can create biological-like structures. The same can happen with many minerals that biomorphs can create that look like biological fossils.

According to the authors of the study published in the journal, Journal of the Geological SocietyThere must be many other processes that can produce pseudo-fossils, so scientists will have to be careful with what they find on the red planet, which has been the focus of several studies looking for life.

Therefore, whenever evidence of ancient Martian life emerges, it should always be questioned as this evidence may have been “tampered with” by non-biological processes. In this sense, has there ever been life on Mars?

‘My power is really low’: NASA’s Mars Insight rover prepares to launch from the Red Planet

Published

NASA Lander InSight He has delivered what may be his last message from Mars as he embarks on a historic mission to uncover the secrets of the Red Planet’s interior.

In November, the space agency warned that the probe could be running out of time as dust continued to condense and stifle InSight’s power.

“Spacecraft power generation continues to decline as windblown dust accumulates on solar panels,” NASA said in a statement. Update November 2. “The end is expected to come in the coming weeks.”

message shared NASA The InSight Twitter account tweeted on Monday: “My power is very low so this might be the last photo I can upload. Don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will—but I will.” Subscribe here soon. Thank you for staying with me.”

A geologist robot armed with a hammer and a seismograph first reached the barren expanse of Elysium Planitia in November 2018.

Since then, she has carried out geological excavations, taking the first measurements of earthquakes with a high-tech seismometer placed right on the surface of Mars.

Last month, the solar-powered car released an update to remind us of its time in space.

“I was lucky to live on two planets. Four years ago I made it safely to the second one, much to the joy of my family at first. Thanks to my team for taking me on this journey of discovery. I hope I can be proud of you.”

According to the published mission, Insight has measured more than 1,300 seismic events since it was published, and more than 50 of them had signals clear enough for the team to extract information about their location on Mars. Results.

The probe’s data also provided detailed information about Mars’ interior, liquid core, surprisingly variable remnants beneath the surface of an extinct magnetic field, climate and seismic activity.

old for Its launch in 2018NASA Chief Scientist Jim Green said the mission was “fundamental to understanding the origins of our solar system and how it became what it is today.”

NASA will not declare the mission complete until Insight confirms the arrival of two spacecraft orbiting Mars that are relaying their information back to Earth.

In 2018, the veteran rover announced the capabilities end of his 15 year stay Sending an incomplete photo of the Valley of Perseverance.

A severe dust storm darkened the sky around the solar-powered rover, shattering the sun and leaving behind a dark image with white spots due to camera noise. The transmission is interrupted before the complete image can be transmitted.
