Ugh, they're really gonna risk getting stuck in that rock formation for a week. Like what if their arm gets jammed or something? They're just gonna pause all their research because of one little drilling operation...
And don't even get me started on how they're trying to analyze the sample later. It's like, can't they just send it back to Earth already? I mean, what's the hurry?
The whole point of sending a rover to Mars is to study it from afar, not to risk getting their equipment all messed up...
