NASA SpX-18 mission patch |
The same Dragon capsule has previously flown to the ISS in April 2015 and December 2017.[8] This was the first time a capsule was used for a third flight.
Primary payload
In February 2016, it was announced that NASA had awarded a contract extension to SpaceX for five CRS additional missions (CRS-16 to CRS-20).[9]
NASA has contracted for the CRS-18 mission from SpaceX and therefore determines the primary payload, date/time of launch, and orbital parameters for the Dragon space capsule. It carried the third International Docking Adapter (IDA-3).[10]
The following is a breakdown of cargo bound for the ISS:[11]
- Science investigations: 1,192 kg (2,628 lb)
- Crew supplies: 233 kg (514 lb)
- Vehicle hardware: 157 kg (346 lb)
- Spacewalk equipment: 157 kg (346 lb)
- Computer resources: 17 kg (37 lb)
- External payloads: IDA-3 534 kg (1,177 lb)[12]
The Dragon spacecraft also featured a handful of ceramic heat shield tiles, meant to flight-test a critical component of the SpaceX Starship spacecraft.[13]
