I have been following the Phoenix mission a bit. Looks promising. Really, I cant believe the last landers opportunity and spirit are *still* running! They expected them to last only 3 months or so, ...maybe. Its been, what, 4 years!?!?! Thats engineering.
The contractors that made the robotic arm for the phoenix used Solidworks, and analyzed it using the physics addons to solidworks too. Delivered the whole thing in like 5 months or so. Which is amazing when you consider target specs are much more specific for space...you have physical size, weight and operating characteristics that are constrained way above normal. An earlier example, spirit and opportunity turned out a little to heavy, that made the fuel needed more, so larger craft, which demanded larger parachutes, etc....a cascading problem.
