Space Station Reboost
The International Space Station (ISS) occasionally has to boost itself into a higher altitude to counteract the effects of microgravity drag. Recently, the ISS boosted itself about two miles up, and video cameras caught what happened inside to Commander Mike Fossum and Flight Engineers Satoshi Furukawa and Sergei Volkov. The physics of the process are explained at Bad Astronomy Blog. Link -Thanks, Phil!
