So SpaceX are on a hot streak, having successfully landed their ‘first-stage booster’ back on earth recently (complete with epic timelapse photos HERE).
Here’s CapeTownExpress with why this docking at the International Space Station (above us, nogal) is rather important:
Among its cargo, the rocket will be carrying one of two docking rings to the International Space Station, a crucial step in enabling U.S. commercial space taxis to ferry astronauts to the orbiting lab.
After the metal docking ring attaches to a berthing port on the station, it will serve as a parking space for commercial spaceships under development by SpaceX and Boeing. The manned craft are scheduled to begin test flights next year.
