In his recent long piece on spacedaily.com Bruce Moomaw reports:
... JPL's Pete Theisinger and Mike Meyer (chief engineer and scientist of the 2009 Mars Surface Lab) confirmed that the current plan is to have MSL land using a strange, Rube Goldbergian system called "Skycrane". Skycrane is a very innovative landing system and now that MSL appears to be planning to use this approach there are lots of open questions, such as: How exactly does it work? What advantages does it have over legs, airbags or pallets? What the heck is it anyway? Some background info: JPL note Space.com article -------------------- |

Also, in regard to Erwan's comment: I have heard that the average new automobile sold now contains more computing power than the Lunar Module did.

The LM's computer was very very slow compared to todays PC's, and when the Eagle landed it was overloaded and Armstrong had to land manually with only a few seconds of fuel remaining for the descent engine.
