Objectives included studying X-rays given off by the coronae of stars, and locating and mapping X-rays given off by the remains of supernovae occurring in the Milky Way galaxy.

According to a DLR study, as many as 30 individual pieces could survive the fires of re-entry.
The largest single fragment would likely be the telescope's mirror, which is very heat resistant and may weigh as much as 1.7 tons.

A one-amd-a-half ton, heat resistant frisbee hitting our thick and heavy atmosphere at some thousands of miles per hour,
I want to see THIS catch.

With tens of thousands of pieces of space junk eventually falling to Earth, sooner or later one will hit a metro area.
Then what? Oh, that’s right, can’t sue the gubmint.

The “Holy City” of Qom Iran, or Musudan Village in N.Korea would be good for starters. And maybe the Castro District of San Francisco. etc. etc. etc.

I've wanted to take one of those and turn it into an underground house. The walls are ‘feet’ thick of reinforced concrete usually, with a connected labyrinth of tunnels.

1.7 tons falling from outer space would hit with a pretty big bang.
Mecca would be messed up....what irony that would be

Will ROSAT fall to earth in one big thud, or enter at an angle and skip a few times before coming to a halt?
(Like a stone skipping on water.)

ROSAT DECAY UPDATE: The massive ROSAT X-ray space telescope continues to descend toward Earth. Latest estimates place the re-entry around noon Universal Time on Oct. 23rd.
Uncertainties exceed 10 hours, which makes it impossible to say exactly where ROSAT will re-enter. Many sky watchers are seeing ROSAT in the night sky shining about as brightly as a 1st magnitude star. Check Spaceweather's Satellite Tracker for local flyby times.

ROSAT DECAY UPDATE: The doomed ROSAT X-ray space telescope continues to descend toward Earth.
Multiple experts agree that re-entry should occur on Oct. 23rd, with most favoring the early hours of the day.
With uncertainties exceeding 8 hours, however, it is still impossible to say exactly where ROSAT will disintegrate.

German Aerospace Center, DLR
On Sunday, 23 October 2011, between 1:45 UTC (3:45 CEST) and 2:15 UTC (4:15 CEST) the German ROentgen SATellite ROSAT has re-entered Earth's atmosphere.
There is currently no confirmation if pieces of debris have reached Earth's surface.
