What we’ve learned about the red planet from 260+ Martian meteorites

NASA’s Perseverance rover successfully touched down on Mars this morning, and has already begun beaming back images.

But people might be surprised to learn there have been another 48 missions to the red planet so far. Of these, more than half failed at stages from take-off to deployment — including the 1999 Mars Climate Orbiter, destroyed on Mars entry after someone failed to convert imperial measurements to metric.

Successful missions include Mars Insight, which is studying the interior via measurement of “marsquakes”, and the Curiosity rover, which touched down in 2012 and has been examining the geology of Mt Sharp.
