NASA: Could Mars Have Harbored Life? NASA’s stunning find in Jezero Crater reveals water, organic materials, and more

An important finding by NASA’s Perseverance rover raises the possibility that microbial life once existed on Mars. In the Jezero Crater, the rover discovered a mixture of organic materials, water, and a chemical energy source on a rock. The greatest proof of possible extraterrestrial life on the Red Planet has been found with this discovery, as per the reports of Yahoo news.

For the past three years, Perseverance has been investigating the 28-mile-wide Jezero Crater. The rover discovered a rock known as “Cheyava Falls,” which contains remains of organic materials, water, and perhaps even chemical reactions. The rock contains a crimson band full of “leopard spots,” which are probably the result of chemical reactions, and two vertical veins of calcium sulfate that were created by water.

Instruments and findings

As per the reports of Yahoo news, Perseverance’s SHERLOC and PIXL instruments found organic molecules in the rock. These “leopard spots” may exhibit chemical reactions that may have given prehistoric bacteria energy. This remarkable finding—that water, organic molecules, and chemical reactions may all coexist in one location—raises the possibility that life once existed on Mars.

This finding is particularly exciting for scientists. Caltech’s Ken Farley stated that Cheyava Falls is the most complex and important rock investigated by Perseverance. The rover’s detection of organic material, chemical reaction indicators, and water evidence strengthens the case for past life on Mars. However, other explanations, like volcanic activity, might also explain these geological features.

Previous discoveries and challenges

Earlier this year, scientists studying Curiosity’s 2017 soil analysis from Gale Crater found an abundance of manganese, which usually requires oxygen and microbes. Despite these discoveries, uncertainties remain. For instance, the presence of olivine crystals, a mineral from magma, suggests volcanic activity could also explain the findings without involving microbes.
