The Perseverance rover has been toiling on the Martian surface for over three years, collecting rock samples that will eventually be brought to Earth if all goes according to plan. But the rover has also picked up hitchhikers, in the form of traces of Martian atmosphere that are squeezed into the “headspace” of the…

NASA is calling on industry players to come up with an alternative plan to return rocky samples from Mars at a lower cost and an earlier date.

The Perseverance rover is at risk of losing its ability to zap Martian rocks with lasers after one of its instruments began malfunctioning last month.
