A defunct German satellite is expected to plunge to Earth this week, but exactly when and where the satellite will fall remains a mystery.
The massive German Roentgen Satellite (http://us.lrd.yahoo.com/_ylt=Alq8fCt4OHFzXR4bjfNewHcbANEA;_ylu=X3oDMTFqMDg xZXM0BG1pdANBcnRpY2xlIEJvZHkEcG9zAzEEc2VjA01lZGlhQ XJ0aWNsZUJvZHlBc3NlbWJseQ--;_ylg=X3oDMTFibnZiMGE1BHBzdGFpZAMxNjdkOGY1Ny04NTQy LTM1ZmMtOWIwNi0zMDViZTI5MDg2MTg-;_ylv=0/SIG=12tpaes26/EXP=1320084193/**http%3A//www.space.com/13261-german-satellite-falling-earth-rosat-risk.html), or ROSAT, is expected to plummet to Earth on Saturday or Sunday (Oct. 22 or 23), though German space officials have also offered a wider re-entry window of between Oct. 21 and Oct. 25. This latest falling satellite comes about a month after a dead NASA climate satellite, called the Upper Atmosphere Research Satellite (UARS), plunged into the Pacific Ocean in late September.
The 2.4-metric ton X-ray space observatory is expected to break up as it travels through Earth's atmosphere, but some large pieces will likely make it through the intense heat of re-entry. According to German aerospace officials, approximately 1.7 metric tons of satellite debris (http://us.lrd.yahoo.com/_ylt=AsasyIWnTFNrNKNBUNV55bkbANEA;_ylu=X3oDMTFqaWd 2Ymg3BG1pdANBcnRpY2xlIEJvZHkEcG9zAzIEc2VjA01lZGlhQ XJ0aWNsZUJvZHlBc3NlbWJseQ--;_ylg=X3oDMTFibnZiMGE1BHBzdGFpZAMxNjdkOGY1Ny04NTQy LTM1ZmMtOWIwNi0zMDViZTI5MDg2MTg-;_ylv=0/SIG=12quffet2/EXP=1320084193/**http%3A//www.space.com/13111-falling-satellite-rosat-november-crash.html), consisting primarily of up to 30 large glass and ceramic fragments, could survive the journey through the atmosphere and reach the Earth's surface.

Oy vey...

Look like the weather channel will need to add another segment... Stay tune for your tropical update, uv index forecast and Space debris forecast after these messages.

ROSAT was designed to work for one and a half year, however it kept working for over 8 years. That what we call value or money!

The chance a part from this satellite will hit sombody is extreme low. As 2/3 of the earth is water and from the land part the majority of the people live relatively close to the sea. So the main land areas do have a low occupation density (is that English?).

When you are lucky and the satellite comes down in your are, you can better enjoy the fiore works and leave your hat-hat home. The largest pieces of debris can be up to 400 kilogrammes, sa a hat-hat won't help you....

Cheers,
