Many thanks, brothers, for the timely tip off! I clicked on the link, and the program started about 40 seconds later.
A polished, broad appreciation of the MERs in particular, and NASAs exploration programs in general.
Of course the medium of radio has its limitations - I would have liked to see a video version - but anything that gets the message out to the masses (or sections thereof) is a step forward. The current public image of NASA gear as the "Energizer Bunnies" of space has come a long way from past views of exploding rockets and crashing probes. Lets hope the positive image is the dominant one from now on!
