This Mastcam-Z image shows a sample of Mars rock inside the sample tube on Sept. 1, 2021 (the 190th sol, or Martian day, of the mission), shortly after the coring operation. The image was taken after coring concluded but prior to an operation that vibrates the drill bit and tube to clear the tube's lip of any residual material.

The bronze-colored outer-ring is the coring bit. The lighter-colored inner-ring is the open end of the sample tube, and inside is a rock core sample slightly thicker than a pencil. A portion of the tube's serial number – 266 – can be seen on the top side of tube's wall.

Arizona State University in Tempe leads the operations of the Mastcam-Z instrument, working in collaboration with Malin Space Science Systems in San Diego.

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 mission to collect and cache Martian rock and regolith (broken rock and dust).

Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.
