MIT geologists determined the original orientation of many of the bedrock samples collected on Mars by the Perseverance rover, depicted in this image rendering. The findings can give scientists clues to the conditions in which the rocks originally formed. Credit: NASA/JPL-Caltech’s Perseverance rover.
“The orientation of rocks can tell you something about any magnetic field that may have existed on the planet,” adds Benjamin Weiss, professor of planetary sciences at MIT. “You can also study how water and lava flowed on the planet, the direction of the ancient wind, and tectonic processes, like what was uplifted and what sunk. So it’s a dream to be able to orient bedrock on another planet, because it’s going to open up so many scientific investigations.
