A bus-sized satellite that's expected to re-enter the atmosphere later this week has sparked "sky-is-falling" headlines around the world.
But it's business as usual at Vandenberg Air Force Base, where a team quietly tracks thousands of objects orbiting Earth on a daily basis.
The Joint Space Operations Center, which tracks objects in space and forecasts their re-entry time, now believes that NASA's Upper Atmosphere Research Satellite will re-enter the atmosphere about dinnertime Friday, Maj. Michael Duncan, deputy chief of space situational awareness for the JSpOC, said Tuesday afternoon.

The UARS Satellite is predicted to be observable from Europe at around 23:30 GMT, 20th September, 2011.
It will pass over southern England, and then over the Baltic sea.

Observable from the UK from ~23:28 to 23:34 GMT.

Ed ~ i had to revise my calculations on the satellite re-entry; the satellite is probably going to re-enter on or around the 23rd September.

A video of the UARS Satellite was taken from Northern France (Dunkerque) on the 15th September, 2011, between 04:42:14 and 04:44:02 UTC.  It shows the "satellite is rotating on itself quite quickly".

The space agency expects the satellite to break into pieces on entry to the atmosphere, and for some of those pieces - some as heavy as 300 pounds - to rain down later this week. Donald Kessler, who served as NASA's senior scientist for orbital debris research, tells Michele Norris that an event of this nature is highly unusual - and odds are slim that the debris will injure people or destroy property.

Ed ~ Worth looking out for though. The UARS Satellite will appear like a silent slow moving aeroplane, as bright as a bright star (mag 3 to 0).
