*BEEP* Come in DARPA Mission Control. We are 1 step closer to capturing retired satellites *BEEP*

SYNCHRONIZED TUMBLING: HOW TO CATCH A RETIRED SATELLITE August 29, 2012 Teams develop algorithms to test the synchronization and capture of tumbling objects in space using mini-satellites aboard the International Space Station In space, there are no brakes. Active satellites and spacecraft achieve controlled movement with thrusters. Retired satellites, on the other hand, no longer controlled from Earth, tumble in their orbits through space while traveling at high speed. A spacecraft seeking to rendezvous with such a satellite must perform a delicate dance to safely approach and synchronize movements. With the help of teams of individuals from around the world, DARPA is beginning to determine the steps required. Their work could inform the design of autonomous control mechanisms for all manner of complex future space operations. Before going big, DARPA started small. Partic...
