Mars dust won’t bury Perseverance rover’s rock sample tubes

Neither dust nor wind nor dark of night will disturb new caches of precious Mars samples on the Red Planet.

This month, NASA’s Perseverance rover has been dropping lightsaber-shaped caches of material on the surface of Mars to lie in wait as backup for a future sample-return mission. Perseverance collects two samples at each location and carries one set with it. If the rover can’t bear the samples in its belly to a waiting spacecraft itself, two fetch helicopters will tote the backup surface tubes to the return rocket instead in the 2030s.
