SpaceX CRS-2, also known as SpX-2, 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 (CRS-1) contract. The launch occurred on 1 March 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 from the station on 26 March 2013, at 10:56 UTC and splashed down in the Pacific Ocean at 16:34 UTC. History The planned shipment of the Falcon 9 first stage from Texas to the Florida launch site was delayed due to the ongoing investigation of the engine failure that occurred on the previous flight. In late November 2012, it was reported that the CRS-2 Falcon 9 had been transported to Cape Canaveral (CCAFS). A static fire test occurred for the CRS-2 Falcon 9 on 25 February 2013. Firsts The Dragon unpressurized trunk section, which allows the transport of unpressurized cargo to the ISS, had its first use on this flight. This cargo consisted of two Heat Rejection Subsystem Grapple Fixtures (HRSGFs), which are essentially bars to be attached to the ISS radiators to allow for future movement work. Payload When launched the CRS-2 Dragon was filled with about of cargo, without packaging. Included is of crew supplies, of scientific experiments and experiment hardware, of hardware for the station and other miscellaneous items, among them a CD copy of the song "Up in the Air" by rock band Thirty Seconds to Mars, was premiered on board the International Space Station (ISS) on 18 March 2013, during a NASA TV broadcast from the station. The two Heat Rejection Subsystem Grapple Fixtures (HRSGFs) had a combined weight of and were transported to the ISS inside the unpressurized Dragon trunk as external cargo. The Dragon returned of cargo, without packaging. Included is of crew supplies, of scientific experiments and experiment hardware, of space station hardware, of spacesuit equipment and other miscellaneous items. Dragon thruster pods anomaly Shortly after second stage separation, at 15:45 UTC on 1 March 2013, the Dragon spacecraft encountered technical problems involving its propulsion system. "When priming its four Draco Thruster Pods, the vehicle detected insufficient pressurization on the oxidizer (Nitrogen Tetroxide) system" of three of the pods which "caused the Flight Computers
