This data shows chemicals detected within a single rock on Mars by the Planetary Instrument for X-ray Lithochemistry (PIXL), one of the instruments on the end of the robotic arm aboard NASA's Perseverance Mars rover. PIXL allows scientists to study where specific chemicals can be found within an area as small as a postage stamp. 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, and be the first miss…
