How will the SpaceX Dragon Capsule dock with ISS (video)->
Dragon will not go directly to the station. First it will carry out a flyby of ISS on Thursday, May 24th. During this flyby SpaceX will assess its sensors and flight systems. It will pass within 1.5 miles (2.4 kilometers) of the outpost.
Assuming this flyby checks out, NASA will attempt to dock the capsule on Friday, May 25th. It is done with the robotic arm as the capsule does not have an automated docking system."
