> Mars has LESS pressure. So the landing would be easier here, so it should have been tested?
No, having less atmosphere is a disadvantage in this case. This means just parachute wont work. Hence the whole sky crane thing. There is no feasible way to test the whole EDL (entry, descend, landing) phase here on this planet because simulating entry into mars's thin atmosphere is not possible out of computer simulations and whiteboards.
