Perseverance Astrobiology Droid Cores ‘Main River’ On Mars
The robotic arm on NASA’s Perseverance Mars rover used its percussive drill to core and collect the “Main River” rock sample on March 10, 2025, the 1,441st Martian day, or sol, of the mission. NASA ID: PIA26571 larger image

The time-lapse movie, taken by one of the rover’s hazard cameras, is made up of 35 images taken over the course of 34 minutes. Animation available at https://photojournal.jpl.nasa.gov/catalog/PIA26571

The sample was taken from a rock the rover science team named “Broom Point” at a location near the rim of Jezero Crater called “Witch Hazel Hill.”

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 Mars Exploration Program (MEP) portfolio and the agency’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
