Brid-Aine Parnell at The Reg updates us on the SpaceX flight schedule:
The flight of the Falcon 9 has once more been rescheduled, with a new launch date of 19 May, as Elon Musk’s SpaceX decided to tweak the software one more time.
The first commercial craft to restock the International Space Station, a Dragon capsule strapped to a Falcon 9 rocket, has seen more than its fair share of push-backs for the test flight, but it will all pay off if the cargo ship can dock with the station.
SpaceX has already shown it can release and retrieve the Dragon, but getting it to motor alongside the fast-moving ISS and accurately berth with it is no mean feat and the firm has tested and retested the necessary software in the hopes it won’t end up with egg on its face.

Providing this test flight is successful, the Dragon will start to fulfil the contract for a minimum of 12 flights to resupply the ISS. Since the ship is reusable, it will be the only spacecraft capable of bringing cargo back with it as well. And, ultimately, SpaceX hopes that a version of the Dragon will be its first manned spaceship as well.
