Reply to comment by Trashleopard in Perseverance sample tube drop by coffeesam

They know where the rover has been and where it dropped the sample. It's not going to get blown away as the strongest wind storm Mars is only as bad as a breezy day on Earth. Might get dusty but the samples should be fine.

How are they going to find samples? There's no GPS on Mars. Right?

NASA's https://mars.nasa.gov/msr/#Overview is scarce on details. Landmark-based navigation, I guess?
