This piece of kit is several orders of magnitude bigger and heavier than any other non-Earth unmanned landing in history.
Pathfinder was the size of a suitcase and landed inside an inflatable ball. Curiosity is the size of a car and weighs several tons.
Putting Neil and Buzz on the Moon was easier than this.

Why do they have to winch it down from the hovering "skycrane"?
The whole thing fails the KISS maxim and instead looks suspiciously like something Gerry Anderson would have built.

they need to use rockets because the parachute can't slow it down enough. If they then just landed on rockets the thing would get covered in dust which could clog up its innards.
