Over millions of years organisms get preserved within layers of sediment that build up on the beds of lakes and other bodies of water.
On earth, almost all fossils are found in sedimentary rocks. Though indications of past life have been preliminarily detected before by both Curiosity and Perseverance during preluding campaigns, the importance of this latest geological discovery is much greater, because of the high concentration of the organic matter, and also the favorable watery-environment in which the material was detected.

Perseverance once again used a drill to collect four more core samples – this time showing more conclusive evidence of organic matter. The once watery environment of this ancient delta is thought to have been an ideal reservoir to support ancient life. Perseverance’s first 31-day campaign within the crater yielded eight rock-core samples that provided striking evidence that ancient water and lava were once present there.įor their second campaign, NASA were able to locate an even more favorable area within the crater, where it is thought a past Martian river would have converged with a lake, denoted by a triangular land-formation known as a “river delta” (so-called due to its geographical resemblance of the shape of greek letter delta Δ). Though only half the size of earth, Mars’ 144.8 million km² surface area of cold, dusty desert makes choosing an ideal excavation site no mean feat.īut, NASA’s astrobiologists were able to pinpoint a specific location within the Martian landscape that Zurbuchen claims is thought to be one of the “best locations on Mars to look for signs of past microscopic life.” This location is the “Jezero Crater.” NASA's Perseverance Mars Rover May 3, 2022 More of your favorite images: /nUmBAlF1iq Mars may be desolate, but it has a certain charm. Making some accidental zen art as I drive. SHERLOC even has a magnifying glass, “just like the fictional detective,” says NASA. “The SHERLOC investigation will advance the understanding of Martian geologic history and identify its past biologic potential,” says Luther Beegle, Principal Investigator at the NASA Jet Propulsion Laboratory. Perseverance uses the SHERLOC spectrometer/laser and the WATSON color camera, to take pictures of “rock grains and surface textures,” and use a UV light laser to detect organic chemicals, all in the search for signs of past alien microbial life.

Since then, Perseverance has expanded on Curiosity’s observational findings with two science campaigns so far, taking on the challenge of mining the surface for evidence of life as an android geologist.

NASA first put robots on Mars 10 years ago, with their inaugural “ Curiosity ” rover searching the Martian terrain for answers to a monumental question: Could Mars have supported ancient life? The answer was yes. The Mars Perseverance Mission, part of an ecosystem of NASA space exploration programs between the Moon and Mars, aims to “characterize the planet’s geology and past climate,” and “pave the way for human exploration of the Red Planet.” “The answers are out there – and Team Perseverance is ready to find them,” says Thomas Zurbuchen, NASA’s Science Chief.
