 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.
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]
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]
