Elon Musk's private spaceflight program, SpaceX, just announced that NASA and Cape Canaveral Air Force Station approved a May 7 launch date for its COTS 2 mission.
The mission is a demonstration launch for NASA's Commercial Orbital Transportation Services (COTS) program, where SpaceX plans to blast a Falcon 9 rocket carrying a Dragon capsule into space. The capsule will (hopefully!) rendezvous and berth with the International Space Station.
The launch had been previously scheduled for April 30, but then Musk announced that the launch was delayed so the company could do more testing of the docking code. Mark your calendars, it's going to be an exciting day.
