This was the fourth flight for SpaceX's uncrewed Dragon cargo spacecraft, the fifth and final flight for the company's two-stage Falcon 9 v1.0 launch vehicle, and the second SpaceX operational mission contracted to NASA under a Commercial Resupply Services contract. The launch occurred on March 1, 2013. A minor technical issue on the Dragon spacecraft involving the RCS thruster pods occurred upon reaching orbit, but it was recoverable. The vehicle was released, splashed down, and recovered by SpaceX.
The Falcon 9 v1.0 first stage was used on the first five Falcon 9 launches, and powered by nine SpaceX Merlin 1C rocket engines arranged in a 3x3 pattern.See Falcon Details
First launch of Dragon using trunk section to carry cargo. Launch was successful, but anomalies occurred with the spacecraft's thrusters shortly after liftoff. Thruster function was later restored and orbit corrections were made, but the spacecraft's rendezvous with the ISS was delayed from its planned date of 2 March until 3 March, when it was successfully berthed with the Harmony module. Dragon splashed down safely in the Pacific Ocean on 26 March.Dragon 1 Details
