NASA SpX-11 mission patch
SpaceX CRS-11, also known as SpX-11, was a Commercial Resupply Service mission to the International Space Station, launched successfully on 3 June 2017. The mission was contracted by NASA and was flown by SpaceX. The mission utilized a Falcon 9 launch vehicle and was the first reuse of C106, a CRS Dragon cargo vessel that was previously flown on the CRS-4 mission.
CRS-11 was the penultimate of the first twelve missions awarded to SpaceX under the Commercial Resupply Services contract to resupply the International Space Station.
Rocket and spacecraft
CRS-11 launched aboard a Falcon 9 rocket on 3 June 2017 at 21:07 UTC from Kennedy Space Center's Launch Complex 39A. The spacecraft rendezvoused with the station on 5 June and conducted a series of orbit adjustment burns to match speed, altitude, and orientation with the ISS. After arriving at the capture point at 13:37 UTC, the vehicle was snared at 13:52 UTC by the Canadarm2, operated by Peggy Whitson and Jack Fischer. It was berthed to the Harmony module at 16:07 UTC.
The CRS-11 Dragon remained attached to the ISS for just over 27 days. Having been filled with around 1,900 kg (4,100 lb) of cargo, Dragon was unberthed from the station on 2 July 2017 at approximately 18:00 UTC. It was moved to its release position by Canadarm2, but poor sea conditions forced a delay to the following day. On 3 July at 06:41 UTC, crew members commanded Canadarm2 to release Dragon, and soon after the spacecraft began a series of thruster firings to move it away from the station. About five hours after departing from ISS, Dragon closed its GNC bay door and conducted a 10-minute deorbit burn. Immediately after, the spacecraft jettisoned its cargo trunk and oriented itself for reentry. Dragon splashed down in the Pacific Ocean off Baja California at 12:12 UTC.
NASA has contracted for the CRS-11 mission from SpaceX and therefore determines the primary payload, date/time of launch, and orbital parameters for the Dragon space capsule. CRS-11 carried a total of 2,708 kg (5,970 lb) of material into orbit. This included 1,665 kg (3,671 lb) of pressurised cargo with packaging bound for the International Space Station, and 1,002 kg (2,209 lb) of unpressurised cargo composed of three external station experiments: NICER, MUSES and ROSA.
The following is a breakdown of cargo bound for the ISS:
- Science investigations: 1,069 kg (2,357 lb)
- Crew supplies: 242 kg (534 lb)
- Vehicle hardware: 199 kg (439 lb)
- Spacewalk equipment: 56 kg (123 lb)
- Computer resources: 27 kg (60 lb)
- External payloads:
A constellation of five CubeSats was also carried on the mission as part of Birds-1, one each from the countries of Japan, Nigeria, Bangladesh, Ghana, and Mongolia. The satellites from Bangladesh (BRAC ONNESHA), Ghana (GhanaSat-1), and Mongolia (Mazaalai) were those countries' first satellites in space.
