If dropped from 10,000 meters a RR SC (Like Bagheera) would :
Hit a terminal volocity of about 442 Meters a second (No Aerodynamics in this, hell its a Rover, why bother, they dont have any :) )
Force of the Impact would be 149.4 Million Newtons
And energy expended on impact (Assuming it bounced a few meters) a scary 298.8 Megajoules
OR
The same energy as 373500 peanuts being burned.
Thus ends this transmission...
