NASA's Perseverance rover celebrated its 1,500th day on Mars with a spectacular new selfie that featured a surprise guest: a tiny dust devil.
Scientists created the Mars rover's newest self-portrait by stitching together 59 individual images taken by Perseverance's camera, which is located at the end of its robotic arm. Each shot required the arm to be precisely positioned, involving 62 carefully coordinated movements over the course of about an hour, according to a NASA statement.
