[ExI] nanosail d might be tumbling, damn {8-[

Whenever it flashes like this, it isn't a good sign:

SOLAR SAIL FLASHES: NASA's Nanosail-D, the first solar sail to orbit Earth,
is flashing as it glides through the night sky.  Observers in Europe report
luminous peaks as bright as a 1st magnitude star.  The irregular period of
the flashes suggests that the sail might be tumbling, although no one is
certain at this moment what is causing the phenomenon.  Sky watchers are
encouraged to check the Simple Satellite Tracker for local flyby times and
watch this unique spacecraft strobe overhead: http://spaceweather.com/flybys
