Margin’ up the Crater Rim!

Since beginning its steep drive up the crater rim, Perseverance has been traversing along the edge of the margin unit (the margin of the margin!), an enigmatic unit rich in carbonates, a mineral group closely linked to habitability. Here, the rover team scouted out a mound of rock called “Specter Chasm,” where Perseverance cleared away the dusty, weathered surface with its trusty abrading bit. The resulting abraded patch, called Eremita Mesa, is pictured above being investigated by Perseverance’s proximity science instruments mounted on its robotic arm. This includes taking close-up images to examine the millimeter-scale particles that make up the rock, using the WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera, which functions as Perseverance’s magnifying glass.
