Just a week after NASA signed off on its launch, SpaceX has had to postpone the flight of the Dragon. It's yet another delay to NASA's efforts to supply the International Space Station using private spacecraft and reduce the US's dependence on Soyuz rockets. Taking to Twitter, founder Elon Musk said that the company needed to do more testing on the docking code for the capsule, while spokesperson Kirstin Brost Grantham told Space.com that the company needed more time to test and review the hardware. Pending NASA's approval, it'll begin its journey heavenward on the head of a Falcon 9 between May 3rd and May 7th. Given that the original mission was scheduled for November last year, they'll probably need to check the use-by dates on those space rations.
Update: Elon Musk has confirmed, via Twitter, that Falcon 9 and Dragon will lift off on May 7th and rendezvous with the ISS. So long as "the company" doesn't detour them to some mysterious rock first.
