When you consider it takes about 11 minutes for a radio signal to get to or from Mars it shows just how much autonomy and computing was involved in the plan..Yes it is pretty extraordinary. Didn’t realise they are collecting samples to be retrieved and sent to earth by future missions.
How cool is that.
Maybe one day we ( as in the human race ) will see us crack FTL comms but I am pretty sure it will not be in my lifetime..
Then again, I never expected to see a mission supplying so much info about the red planet in my lifetime, so I guess anything is possible...
Quantum mechanics is a field almost too far for my mundane brain to grasp !
