The Mars rover Perseverance has pebbles stuck in its drill. NASA has a plan to fix it.

NASA’s Perseverance rover will dump its latest Mars sample to unclog pebbles from its drill. 

Perseverance mission managers made the unexpected announcement that they had to dump out Percy’s latest sample via a blog post on Friday (Jan. 14). The team even shared in the post that they never thought they would have to do that as one of Perseverance’s main goals is to pick up Mars samples for future analysis.
