Perseverance finds ‘something that no one has ever seen’ in the search for aliens

The Perseveranceover “took a look at something no one has ever seen” by scratching rocks on the surface of Mars.

The rover has been on the Red Planet since October 25, exploring the South Séítah region of Jezero Crater as part of NASA’s search for extraterrestrial life – but recently took a brief pause during solar conjunction when the sun was communicating between Earth and Mars blocked for the space agency.

In addition to looking for microbial life, the rover will also bring samples of Martian geology so scientists can develop a more accurate history of the planet’s climate.

It used its abrasive tool to scrape off the foreign rock to examine the minerals inside.

“Peek inside to see something no one has ever seen. I sanded down a small patch of this rock to remove the surface layer and take a look underneath. Aiming for my next target for #SamplingMars, ”read a post from the rover’s official Twitter account.

The rover revealed a circular hodgepodge of minerals and sediments in one of the crater’s stratified rocks – which scientists can use to tell when the material was formed and what the climate was like.

It was recently revealed that Jezero Crater was home to an ancient river delta, with the presence of water increasing the likelihood that life existed on Mars.

Perseverance has 43 sample tubes to bring Martian debris back for scientists to study, and recently collected its first “perfect” rock sample (after a previous sample mysteriously disappeared). It is likely that the space agency will now take a new sample from this area. If so, these rocks could be even older than those previously collected.

“We have potentially older rocks in front of us in the South Séítah region, so this younger sample can help us reconstruct the entire timeline of Jezero,” said Vivian Sun, one of the mission scientists at NASA’s Jet Propulsion Laboratory in Southern California said in August 2021.
