JUPITER MOON MOVIE: An amateur astronomer in Australia has photographed a 
very rare event--one of Jupiter's moons eclipsing another.  Earth is now 
passing through the orbital plane of Jupiter's satellite system allowing 
such "mutual occultations" to be seen through backyard telescopes.  Check 
http://spaceweather.com for a movie of Europa passing directly in front of 
Ganymede and links to more information for observers who wish to try to 
record such movies themselves.

SATELLITE DEBRIS:  On Feb. 10, 2009, Iridium 33 crashed into Cosmos 2251 and 
the two satellites were shattered.  Since then, US Strategic Command has 
catalogued nearly a thousand pieces of debris.  Today's edition of 
http://spaceweather.com presents 3D maps showing where the fragments are 
located on the three-month anniversary of the unprecedented collision.  One 
large piece of Iridium 33 wreckage is visible to the naked eye as it tumbles 
through the night sky flashing every 4.7 seconds. Check the Simple Satellite 
Tracker for flyby times:  http://spaceweather.com/flybys
