SpaceX CRS-12, also known as SpX-12, was a Commercial Resupply Services mission to the International Space Station launched on 14 August 2017. The mission was contracted by NASA and was flown by SpaceX using a new Dragon capsule.[8] The Falcon 9 rocket's reusable first stage performed a controlled landing on Landing Zone 1 (LZ1) at Cape Canaveral Air Force Station.[9] After delivering more than 2900kg (6,400lb) of cargo, the Dragon spacecraft returned to Earth on 17 September 2017.
CRS-12 is the last of the original order of twelve missions awarded to SpaceX under the CRS contract.[10] Originally scheduled for December 2016, the flight was delayed multiple times to August 2017.[11] Launch occurred on 14 August 2017 at 16:31:37 UTC from Kennedy Space Center Launch Complex 39A aboard a SpaceX Falcon 9 rocket. After Dragon rendezvoused with the ISS on 16 August 2017, the station's Canadarm2 grappled the spacecraft at 10:52 UTC. It was then berthed to the Harmony module at 13:07 UTC.
Having been at the ISS for a month, the CRS-12 Dragon capsule was unberthed in the late hours of 16 September 2017 and was released by the Canadarm2 on 17 September at 08:40 UTC. After performing separation burns to take it out of the vicinity of the ISS, the Dragon performed a deorbit burn to enable atmospheric reentry. The spacecraft successfully landed in the Pacific Ocean at 14:14 UTC, returning approximately 3800lb of experiments and equipment to Earth.
NASA has contracted for the CRS-12 mission from SpaceX and therefore determines the primary payload, date/time of launch, and orbital parameters for the Dragon space capsule. CRS-12 carried a total of 29100NaN0 of material into orbit. This included 16520NaN0 of pressurised cargo with packaging bound for the International Space Station, and 12580NaN0 of unpressurised cargo composed of the CREAM instrument, to be mounted externally to the ISS.
The following is a breakdown of cargo bound for the ISS:
