Well, I've been out of touch for awhile. Now getting back into the 3D bit... I was recruited to design a Mars Lander for a video project.
Check out this thing in the works... Will have more thruster rockets and related details soon.
When finished, the lander will descend to the Martian surface, land and open up "flower petal" style, releasing a rover type vehicle.

Some of the other images in that photobucket show rough ideas for the Mars Lander stages.
Also, some preliminary basic mock-up experiments to be found here:
