The US space agency (Nasa) is about to put its latest rover, Perseverance, on Mars. But we shouldn’t forget that the existing robot, Curiosity, is still there and working well following its landing in equatorial Gale Crater back in 2012. Curiosity celebrates 3,000 Martian days, or Sols, on the surface of the Red Planet on Tuesday. The
Mission Science Team has collected together a series of pictures that record some of the rover’s major achievements.
