In recent research published in the journal Science Advances, a team of scientists led by the University of California, Los Angeles (UCLA) and the University of Oslo revealed that Jezero Crater, which was formed by an ancient meteorite impact, was filled with water. At some point in its Martian history. This discovery not only supports the theory that Mars was wetter in the past, but also reinforces NASA's growing confidence that the red planet could have supported life.
NASA is increasingly certain that there is life on Mars
In a recent research published in the journal Science Advances, scientists from the University of California, Los Angeles (UCLA) and the University of Oslo revealed that the Jezero Crater, the result of an ancient meteorite colliding with Mars, It was filled with water at some point in its history. This discovery strengthens the hypothesis that Mars could have hosted microbial life.
The Perseverance rover has so far collected many samples in this crater, using the Radar Imager for the Mars Subsurface Experiment (RIMFAX). This way he can Analysis of the structure of sedimentary layers. The images revealed two periods of sedimentation interspersed with erosion, providing evidence of an ancient lake and delta formed by the river.

Rover, the size of a car, Collected rocks and dust, showing signs of organic compounds. Although it is still uncertain whether these samples have a biological origin, the samples will be sent to Earth by a future expedition planned by the European Space Agency (ESA).
“From orbit we can see a lot of different deposits, but we can't say with certainty whether what we're seeing is their original state or whether we're seeing the conclusion of a long geological history,” commented David Page, professor of Earth, planetary and space sciences at UCLA. This research also states: “A more complete understanding of these events may need to wait until Perseverance samples are returned and analyzed.”
