Aluminum geodesic mesh in inflatable disolving plastic sphere satellite

The Mylar Echo satellites didn't stay up long, becuase the suns heat would deform them and slow them down. The answer was this system where a helium inflated plastic sphere would expand a signal reflecting hollow mesh, with the plastic dissolving under the suns rays. The mesh could then stay up for 11 years or so.

I don't know why they made the "landing airbag" balloons bounce the lander (well, according to all the animations I've seen...). Designing them to "burst" like a high-dive crashpad would be far better.
