Encore post - ScienceCasts: NanoSail-D

Given yesterday's post regarding flashes produced by NASA's NanoSail-D I thought it would be appropriate to post this video that was originally posted at ScienceAtNASA on Feb 18, 2011

"High overhead, out of the darkness, a bright light surges into view. For 5 to 10 seconds it outshines the brightest stars in the sky, mimicking a supernova, perhaps even casting faint shadows at your feet. The silence is broken by your own excited shouts. Could this happen to you? It could, if you happen to be outside when NanoSail-D flies by."
