Space for All posted a link to a
radio report by the Bay Area's KQED with a good overview of the NASA PAV Centennial Challenge. The report also has some links on the challenge, including the some of the photos and videos I've linked in earlier (but less convenient to access) posts. Here's a link they provide to their
Quest Community Science Blog, with an overview and some interesting reader/listener comments on the PAV radio report.
