SpaceX Grasshopper has some sexy legs

Back in December SpaceX flew the Grasshopper) VTVL demonstrator to 40 meters. Today they released a new video showing more details about the landing system:

There is a long history of VTVL vehicles having problems with landing legs. The entire flight can go fine but the last few seconds are extremely important. What isn't known is whether the system shown in the video has any relation to the final operational design. Its an interesting design but looks awfully heavy. While I was at Masten we iterated on several designs that optimized for aerodynamics and stowability, shock absorption, and simplicity. From what I've seen from Masten those iterations continue.

I haven't actually built a model but others have. Regardless of short term affects, reusability is the only way you can reduce launch costs that doesn't require new physics. What SpaceX is doing with Grasshopper shows that Elon is serious about reusability and the capabilities that cost reduction brings. Ad astra lucustae?
