The level of interest among non-NASA agencies to use the ISS could ultimately decide how long the space station remains in operation beyond its current 2016 design lifetime, they added.
"Technically, the space station could fly to 2020 or 2022," Gerstenmaier said, adding that a decision on whether to extend the station's lifetime would have to be made around 2014. "What really drives the practical lifetime of the space station is how useful it is and does it fit a niche."

The orbit would naturally deteriorate anyways and to leave it would mean it would become a junk-hazard in space for all the stuff we really need up there like weather and military and communications sattilites.
A 1999 study estimated there are some 4 million pounds of space junk in low-Earth orbit, just one part of a celestial sea of roughly 110,000 objects larger than 1 centimeter -- each big enough to damage a satellite or space-based telescope.
But what does Suffredini really think? As he told the Augustine Commission, "My opinion is it would be a travesty to de-orbit this thing."
