NASA’s Perseverance rover has spent a busy two weeks settling into its new home on Mars, most recently flexing its robotic arm for the first time.

Perseverance touched down on the Red Planet on Feb. 18 to begin work looking for traces of ancient life and selecting rock samples for a future mission to carry to Earth’s laboratories for much more thorough examination. But before “Percy” sets off on those scientific adventures, the car-sized robot must first warm up, so to speak, testing its components and confirming nothing was damaged during the perilous landing.
