I have to admit I've always been sceptical about the sample return part*. Not that it can't be done, but with,what - eight successful landers, 4 being rovers, JPL (not NASA ;) ) has a lot of experience getting there, and none at all with coming back. It's a hard problem, and it would be pretty extraordinary if the whole architecture for MSR worked all the way through, first time.
Fortunately, Mars isn't going anywhere...
*Not as much as the insane idea of landing Starship on the moon (after 16 full-stack launches, no less, before leaving LEO. It'll never work, I tell you!)
