#NASA satellite expected to hit Earth this week - The Washington Post
By Joel Achenbach, Published: September 18
The sky is not falling. A 12,500-pound NASA satellite the size of a school bus is, however.
It’s the Upper Atmosphere Research Satellite, or UARS — YOU-arz — and it’s currently tumbling in orbit and succumbing to Earth’s gravity. It will crash to the surface Friday.
Or maybe Thursday. Or Saturday.
Out-of-control crashing satellites don’t lend themselves to exact estimates even for the precision-minded folks at NASA. The uncertainty about the “when” makes the “where” all the trickier, because a small change in the timing of the reentry translates into thousands of miles of difference in the crash site.
