SpaceX CRS-13, also known as SpX-13, was a Commercial Resupply Service mission to the International Space Station launched on 15 December 2017.

[11] In early 2015, NASA awarded a contract extension to SpaceX for three CRS additional missions (CRS-13 to CRS-15).

[6][7] The spacecraft deorbited a few hours later, splashing down in the Pacific Ocean at 15:37 UTC carrying 1,850 kg (4,078 lb) of equipment and science experiments.

[3] 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.

This includes 1,560 kg (3,439 lb) of pressurised cargo with packaging bound for the International Space Station, and 645 kg (1,422 lb) of unpressurised cargo composed of two external station experiments: the Total and Spectral Solar Irradiance Sensor (TSIS) and the Space Debris Sensor (SDS).
