While searching around for information on the wheel design for Mars 2020, I found this interesting YouTube video of Honeybee's (proposed?) Drill/Sample/Cache system.

I did not find any info on the wheels but perhaps I don't know where to properly look.

Dear Admin! The issue of is question concerns both sample acquisition system (including depot/caching) and the Mars Sample return mission. If you consider its current placement improper, please move in to the more relevant topic/section. Thank you.


Question. Is the entire sample acquisition system including its robotic arms, and inner storage facilities capable to replenish the stock of sample tubes if such shall be brought to Mars together with the pair of collecting helicopters?

The idea is to bring new stock of tubes, one by one, to the same depot place where Perseverance brought the filled-and-sealed tubes.

That may effectively use the capacities of Perseverance (including the stocks of gas used to clear abrasion patches) after the initial 43 tubes set shall be returned to Earth. Given Perseverance shows no less longevity than Curiosity, the searches of life signatures could be continued in the perspective locations outside the crater rim where the sediments could accumulate before Neretva made its way into Jezero.

Not like this. there are two caches, one at Three Forks with the first set of samples, the second much later outside Jezero with a full set of samples (that's why we are getting two cores at each location now). If Perseverance fails later the first cache is here as a backup to the full set in case that is irretrievable.

Of course not. That's sort of like expecting a Coke machine to reload itself if you just leave new cans next to it on the floor, isn't it?
