The launch was successful, and the capsule is on its way to the space station.was postponed due a helium leak on the Falcon 9 rocket's first stage.
"We have brought the vehicle back to horizontal and are replacing the faulty valve, as well as inspecting the whole system for anything that may have contributed to the valve not working as designed, " SpaceX said in a status update on Thursday.

SpaceXThe landing legs on a private SpaceX Falcon 9 rocket launching from Cape Canaveral Air Force Station, Fla., April 14, 2014.This launch is particularly exciting because it's the first time Falcon 9's first stage is equipped with four "landing legs, " which are part of a test to see if the rocket can be recovered and reused.
The legs should pop out as the rocket is performing its landing maneuvers above the ocean's surface. The legs won't support it in the water so it will fall over and be recovered by the SpaceX team. The company hopes to eventually land the first stage on the ground.
SpaceX previously said that the chances of this procedure working correctly and resulting in the first stage actually being recovered are low, placing at the odds of success at between 30% and 40%.
A reusable rocket is part of SpaceX founder's Elon Musk's grand plan to make the future of commercial travel much cheaper, since the cost of fuel is much less compared to the cost of building a rocket from scratch every time.
