Mars dust will not bury Perseverance’s rock sample tubes on Mars

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

This month, NASA’s Perseverance rover dropped caches of lightsaber-shaped material on Mars to wait as a backup for a future sample-return mission. Perseverance collects two samples at each site and carries with it one collection. If the rover cannot carry the samples in its belly to a waiting spacecraft, two helicopters will load the spare surface tubes on the return rocket instead in the 2030s.
