NASA’s new rover Curiosity just landed on Mars Sunday night, and it’s already behaving like quite the tourist. The rover, which is on the Red Planet searching for evidence that Mars once harbored or could in the future harbor microbial life, snapped its first color image of its surroundings Tuesday, revealing the north wall and rim of Gale Crater. The success of the picture proved that key instruments were in good working order following the rover’s dramatic descent to the planet’s surface Sunday.
