Details may change as the countown and ascent progress. Launch details: SpaceX will use a Falcon 1 to launch Trailblazer and two CubeSats for the American Air Force and MDA, and for Malaysia's ATSB. Launch will occur from Omelek Island at Kwajalein Atoll. A Celestis Space burial payload, Explorers, including the remains of astronaut Gordon Cooper and Star Trek actor James Doohan is also being flown. If the launch is successful, it will be the first privately funded liquid-fuelled rocket to reach low Earth orbit.
