Three days ago SpaceX made history by becoming the first private company to launch an unmanned craft into space. Today that rocket successfully completed another stage of the mission by bolting the "Dragon" capsule to the Harmony module of the International Space Station at 12:02 p.m. EDT. The capsule was full of supplies and other cargo for the station. You can watch the unhatching of the capsule tomorrow at 4:25 a.m. tomorrow or check out the live stream from the ISS below.
