The large ROSAT satellite re-entered Earth's atmosphere a few hours ago, but the German space agency, which had operated ROSAT, couldn't immediately say exactly where pieces of the satellite came down. Similarly, when UARS fell to Earth last month, NASA couldn't say where pieces had fallen until it got help from Defense Department tracking assets.
Presumably, those assets will be used again, especially since ROSAT was a joint German, British, and American project.
