In October or November 2011 a second larger sat will be reentering.
Another event for additional observation of meteor-like bodies.

"When the spacecraft re-enters the atmosphere at a speed of
approximately 28,000 kilometres per hour, the X-ray observatory will
break up into fragments, some of which will burn up by the extreme heat.
The latest studies reveal that it is possible that up to 30 individual
pieces weighing a total of 1.6 tons may reach the surface of the Earth.
The largest single fragment will probably be the telescope's mirror,
which is very heat resistant."
