PERSEVERANCE ON MARS

Perseverance might not be the first rover to land on Mars – a small plaque mounted on it shows it is the youngest member of a ‘family tree’ of Red Planet rovers – but it is certainly the most capable so far. Almost groaning under the weight of cameras and scientific instruments, nuclear-powered Perseverance set down safely on Mars in a cloud of billowing orange dust on 18 February, and since then has begun to explore Jezero crater.

Perseverance’s mission is simple and exciting: it’s on a quest to look for evidence that Mars once had life. It will do that by studying rocks and material inside the crater, specifically within the layers of ancient sediment that form a striking, fan-shaped delta that pushes into the crater from the west.
