CAPE CANAVERAL, Fla. (AP) SpaceX is gearing up for its third astronaut launch in under a year, after getting the green light from NASA a week ahead of next Thursdays planned flight.
Managers from NASA and Elon Musks space company Thursday cleared the Falcon rocket and Dragon capsule for a dawn liftoff with a crew of four to the International Space Station. They will spend six months at the orbiting lab, replacing another SpaceX crew thats close to coming home.
The rocket and capsule were designed for reuse. The rocket was used to launch the current station crew last November from NASA's Kennedy Space Center. The capsule, dubbed Endeavour, also will be making a repeat performance; it carried two test pilots to the space station on SpaceXs first crew flight last spring.
SpaceX refurbished both and added safety upgrades. Most of the capsule is already flight proven, company officials noted, except for some new valves, thermal protection covers and parachutes.
Three of the astronauts are back for their second space station mission: NASAs Shane Kimbrough, Frances Thomas Pesquet and Japans Akihiko Hoshide. NASA astronaut Megan McArthur was part of the final Hubble Space Telescope repair team in 2009.
