Meet the Perseverance Rover's Mars Samples: Comet Geyser | NASA/JPL

Meet the 24th Martian sample collected by NASA’s Mars Perseverance rover “Comet Geyser,” a sample taken from a region of Jezero Crater that is especially rich in carbonate, a mineral linked to habitability. When the rover used its abrasion bit to grind away the surface of the rock, cameras showed interesting and diverse textures. It also spotted silica and carbonate, minerals that scientists know have the highest potential to preserve signs of ancient life on Earth. 

Could it have preserved signs of ancient life on Mars?

As of early April 2024, the Perseverance rover has collected and sealed 24 scientifically selected samples inside pristine tubes as part of the Mars Sample Return campaign. The next stage is to get them to Earth for study. 

Considered one of the highest priorities by the scientists in the Science and Astrobiology Decadal Survey 2023-2032, Mars Sample Return would be the first mission to return samples from another planet and provides the best opportunity to reveal the early evolution of Mars, including the potential for ancient life. NASA is teaming with the European Space Agency (ESA) on this important endeavor.

A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, as well as be the first mission to collect and cache Martian rock and regolith (broken rock and dust).
