Space Junk HD

Swiss Space Center at EPFL's the "CleanSpace One" project. The aim is to design and build a satellite that will chase, grab and destroy a space debris - namely one of the first Swiss satellites, Swisscube-1 or TIsat-1.
After its launch, the cleanup satellite will have to adjust its trajectory in order to match its target's orbital plane. To do this, it could use a new kind of ultra-compact motor designed for space applications that is being developed in EPFL laboratories. When it gets within range of its target, which will be traveling at 28,000 km/h at an altitude of 630-750 km, CleanSpace One will grab and stabilize it -- a mission that's extremely dicey at these high speeds, particularly if the satellite is rotating. To accomplish the task, scientists are planning to develop a gripping mechanism inspired from a plant or animal example. Finally, once it's coupled with the satellite, CleanSpace One will "de-orbit" the unwanted satellite by heading back into the Earth's atmosphere, where the two satellites will burn upon re-entry.
