Mission Rundown: SpaceX Falcon 9 Block 4 - CRS-14
Written: Januar 10, 2021
We just keep hauling their stuff
NASA commissioned SpaceX to launch a Falcon 9 Block 4 with a Dragon on a resupply mission to the International Space Station. The Falcon 9 booster B1039-2 is on its second and last launch into orbit.
SpaceX is targeting Friday, April 2 for an instantaneous launch of its 14th Commercial Resupply Services mission (CRS-14) at 16:30:38 EDT, or 20:30:38 UTC, from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. Dragon will separate from Falcon 9’s second stage about nine minutes and thirty seconds after liftoff and attach to the space station on Sunday, April 4.
Both Falcon 9 and the Dragon spacecraft for the CRS-14 mission are flight-proven. Falcon 9’s first stage previously supported the CRS-12 mission in August 2017, and Dragon previously supported the CRS-8 mission in April 2016. SpaceX will not attempt to recover Falcon 9’s first stage after launch, instead the booster was used to conduct experimental maneuvers designed to test the limits of its flight trajectory.
The Dragon Payload
NASA contracted for the CRS-14 mission from SpaceX and therefore determined the primary payload, date/time of launch, and orbital parameters for the Dragon space capsule. CRS-14 carried a total of 2,647 kg (5,836 lb) of material into orbit. This includes 1,721 kg (3,794 lb) of pressurized cargo with packaging bound for the International Space Station, and 926 kg (2,041 lb) of unpressurized cargo placed in the extended Dragon trunk.

The unpressurised component is composed of two external station experiments, Atmosphere-Space Interactions Monitor (ASIM) and Materials ISS Experiment Flight Facility (MISSE-FF), and a Pump and Flow Control Subassembly (PFCS) orbital replacement unit for the station.
Multiple payloads from national labs are also included, one of which is the RemoveDEBRIS mission which will be deployed from the ISS. The mission aims to test a harpoon and a net on test debris that the mission carries to evaluate the viability of these methods to be used in future missions to remove real space debris.
At the end of the mission the RemoveDEBRIS spacecraft will deploy a large dragsail to accelerate its own deorbit to avoid becoming space debris itself. HP was also contracted by NASA to install a new inkjet printer for the US lab.
In early 2015, NASA awarded a contract extension to SpaceX for three additional CRS missions (CRS-13 to CRS-15). CRS 14 is the second of those.
The Cargo Dragon is expected to arrive at the station ISS on Friday, April 4. Once it navigates into position, it will be captured by the Canadarm, and then berthed to the station a few hours later. NASA TV will provide coverage of the arrival, capture and berthing. After about 30 days Dragon will depart ISS, ditch its trunk, reenter the atmosphere and splash down in the Pacific Ocean.
The Dragon splashed down in the Pacific Ocean at 19:03 UTC to be retrieved by a SpaceX recovery crew and transported to the Port of Los Angeles, returning 1,743 kg (3,843 lb) of cargo to Earth.
SpaceX technicians open the side hatch of the Dragon vehicle and retrieve the time critical refrigerated items. The critical cargo items were placed on a fast-boat for the 450 kilometers (280 miles) trip back to California for eventual direct return flight to the NASA laboratories that then took care of the precious science cargo and handled the post-flight analysis of the samples.
The rest of the cargo was unloaded once the Dragon capsule reached SpaceX's test facility in McGregor, Texas.
