SpaceX CRS-13


SpaceX CRS-13, also known as SpX-13, was a Commercial Resupply Service mission to the International Space Station launched on 15 December 2017. The mission was contracted by NASA and is flown by SpaceX. It was the second mission to successfully reuse a Dragon capsule, previously flown on CRS-6. The first stage of the Falcon 9 Full Thrust rocket was the previously flown, "flight-proven" core from CRS-11. The first stage returned to land at Cape Canaveral's Landing Zone 1 after separation of the first and second stage.

Mission overview

In early 2015, NASA awarded a contract extension to SpaceX for three CRS additional missions., a NASA Inspector General report had this mission manifested for September 2017. The flight has been delayed from 13 September, 1 November, 4 December, 12 December, and 13 December 2017. SpaceX pushed off the launch to 15 December due to the detection of particulates in the second stage fuel system, taking the time to completely flush out the fuel and liquid oxygen tanks on the first and second stages as a precautionary measure.
The CRS-13 mission launched aboard a Falcon 9 Full Thrust rocket on 15 December 2017 at 15:36:09 UTC from the Cape Canaveral Air Force Station Space Launch Complex 40. The Dragon spacecraft rendezvoused with the International Space Station on 17 December 2017; the vehicle was captured by the Canadarm2 at 10:57 UTC and was berthed to the Harmony module's nadir docking port at 13:26 UTC. Dragon spent just under a month at the ISS: it was unberthed on 12 January 2018 at 10:47 UTC and was released from Canadarm2 on 13 January 2018 at 09:58 UTC. The spacecraft deorbited a few hours later, splashing down in the Pacific Ocean at 15:37 UTC carrying of equipment and science experiments.

Payload

NASA has contracted for the CRS-13 mission from SpaceX and therefore determines the primary payload, date/time of launch, and orbital parameters for the Dragon space capsule. CRS-13 carried a total of of material into orbit. This includes of pressurised cargo with packaging bound for the International Space Station, and of unpressurised cargo composed of two external station experiments: the Total and Spectral Solar Irradiance Sensor and the Space Debris Sensor.
The following is a breakdown of cargo bound for the ISS:
