ROSAT RE-ENTRY: The ROSAT X-ray observatory, launched in 1990 by NASA
and managed for years by the German Aerospace Center (DLR), will return
to Earth within the next two weeks. Current best estimates place the
re-entry between Oct. 22nd and 24th over an unknown part of Earth. ROSAT
will produce a spectacular fireball when it re-enters, but not all of
the satellite will disintegrate. According to the DLR, heat-resistant
fragments as massive as 1.7 tons could reach Earth's surface. Check

LAST-CHANCE SIGHTINGS: As ROSAT slowly descends it is growing brighter.
During favorable passes, the satellite can now be seen shining as brightly
as a first magnitude star in the night sky. Local flyby times may be found
using SpaceWeather's Satellite Tracker: http://spaceweather.com/flybys .
