NASA’s Perseverance Rover Investigates Intriguing Martian Bedrock
NASA’s Perseverance Mars rover has begun exploring an area the science team calls “Yori Pass” near the base of Jezero Crater’s ancient river delta. They’ve been eager to explore the region for several months after spotting a rock similar to one Perseverance collected samples from in July.
The feature is so tantalizing to the scientists because it is sandstone, which is composed of fine grains that have been carried from elsewhere by water before settling and forming stone. Perseverance’s samples are central to the first step in the NASA-ESA (European Space Agency) Mars Sample Return campaign, which began when the rover cached its first cored rock in September 2021.
