Bits of dead space satellite selling on eBay

If you do manage to catch a chunk of satellite its not going to make a fortune. US government forbids you from selling it on eBay. The burned chunk will remain the property of the United States and must be turned over to local police.

The space agency predicts that the debris from the 20-year-old Upper Atmosphere Research Satellite (UARS) has a 1-in-3,200 chance of hitting a person, a scenario they consider "extremely remote". It is mostly likely the expensive shards will plummet into the sea, NASA said.



Most of the 6.5-tonne craft will burn up in the Earth's atmosphere, but NASA debris experts say that at least 26 large pieces of the satellite will survive the scorching temperatures of atmospheric reentry. The climate taster has been orbiting the Earth, sampling the ozone layer and chemical compounds in the upper atmosphere. When the $750m UARS satellite was launched in 1991, NASA intended it to last for three years.

But it kept going until 2005 when NASA ordered the satellite to burn its remaining fuel and prepare for a suicide dive to Earth. The last of its fuel is now gone, and the UARS has been gradually pulled closer to Earth. Some recent solar activity has also advanced its descent. This activity can cause the Earth's atmosphere to heat and expand, increasing drag on spacecraft.
