SpaceX CRS-1, also known as SpX-1, was the third flight for Space Exploration Technologies Corporation's (SpaceX) uncrewed Dragon cargo spacecraft, the fourth overall flight for the company's two-stage Falcon 9 launch vehicle, and the first SpaceX operational mission under their Commercial Resupply Services contract with NASA. The launch occurred on 7 October 2012 at 20:34 EDT (8 October 2012 at 00:34 UTC).

In May 2012, it was reported that the CRS-1 Falcon 9 had been transported to Cape Canaveral The CRS-1 Dragon later arrived on 14 August 2012. On 31 August 2012, a wet dress reherarsal was completed for the CRS-1 Falcon 9, and on 29 September a static fire test was completed; both of these tests were completed without the Dragon capsule attached to the launch vehicle stack. The mission passed its Launch Readiness Review on 5 October 2012.

The launch occurred on 8 October 2012 (UTC) and successfully placed the Dragon spacecraft into the proper orbit for arriving at the International Space Station with cargo resupply several days later. During the launch, one of the nine engines suffered a sudden loss of pressure about 80 seconds into the flight, and an immediate early shutdown of that engine occurred; debris could be seen in the telescopic video of the night launch. The remaining eight engines fired for a longer period of time and the flight control software adjusted the trajectory to insert Dragon into a near flawless orbit.
