Northrop Grumman makes history, Mission Extension Vehicle docks to target satellite me
They launched a a vehicle and parked it in the orbit where satellites that are decommissioned go. Waited for an opportunity, Docked with a sat put there in December when it ran out of fuel (even though it was not designed for docking) and put it back in service. Didn't even know they were working on this.
