Perserverence’s robotic arm starts science experiments

While Perseverance doesn’t have a rock hammer, it does have other ways to peer past millennia’s worth of dust. When scientists find a particularly enticing spot, they can reach out with the rover’s arm and use an abrader to grind and flatten a rock’s surface, revealing its internal structure and composition. Once they’ve done that, the team gathers more detailed chemical and mineralogical information using arm instruments called PIXL (Planetary Instrument for X-ray Lithochemistry) and SHERLOC (Scanning for Habitable Environments with Raman & Luminescence for Organics & Chemicals).
