JPL has released a brief podcast of the sounds that can be heard from the Mars' rovers Spirit and Opportunity.
The picture above of a "PocketQub" was snapped on a recent trip to Morehead State University to talk with Profs. Bob Twiggs and Ben Malphrus. The personal satellite can be flown with whatever science or technology that can be put inside on missions measured in weeks or months at very low orbital altitudes, and vaporize on reentry into the Earth's atmosphere. This example is sitting on a magazine-sized brochure.
