Mission Rundown: SpaceX Falcon 9 B5 - CRS-17

Written: January 8, 2021

Lift Off Time	May 4, 2019 - 06:48:58 UTC - 02:48:58 EDT
Mission Name	CRS-17
Launch Provider	SpaceX
Customer	NASA
Rocket	Falcon 9 Block 5 serial number B1056-1
Launch Location	Space Launch Complex 40 - SLC-40 Cape Canaveral Air Force Station, Florida
Payload	Cargo Dragon C113-2
Payload mass	2 481 kg ~ 5 500 pounds
Where are the Dragon going?	Low Earth Orbit to the International Space Station
Will they be attempting to recover the first stage?	Yes - OCISLY was moved just a little way from port
Where will the first stage land?	OCISLY placed just 28 km (17 miles) downrange because of the Dragon 2 test anomaly on LZ-1
Will they be attempting to recover the fairings?	No. Dragon capsules have a jettisonable nose cone  and solar panel covers on the Trunk
This will be the: The previous 38th booster landing was a partial success, but also an accidental crash because the Octagrabber couldn't secure the booster safely. It fell overboard and was lost at sea.	– 70th flight of all Falcon 9 rockets – 14th flight of Falcon 9 Block 5 booster – 8th maiden flight of a Falcon 9 Block 5 rocket – 2nd mission for this Dragon capsule C113-2 – 41st SpaceX launch from SLC-40 – 38th successful booster landing overall – 5th mission for SpaceX in 2019

Launch debriefing (This is what happend) If the times given in the articles about CRS-17 are correct then the T+ are too. Local time in Florida EDT is 4 hours earlier. Between the deorbit burn and splashdown it only took 11:22 minutes to get down to Earth. The second count is frozen due to lack of exact seconds given by the UTC times.

Sorry. No Geoff Barrett mission view of CRS-17 - The Falcon 9 height is wrong by 5 meters

Okay. So I’m 5 meter shorter with Dragon

SpaceX CRS-17, also known as SpX-17, was a Commercial Resupply Services mission (CRS) to the International Space Station that was launched aboard a Falcon 9 rocket on 4 May 2019. The mission was contracted by NASA and was flown by SpaceX.

SpaceX is targeting Saturday, May 4 for an instantaneous launch of its seventeenth Commercial Resupply Services mission (CRS-17) at 2:48 a.m. EDT, or 18:48 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 9 minutes after liftoff and attach to the space station on Monday, May 6.

The Dragon spacecraft that will support the CRS-17 mission previously supported the CRS-12 mission in August 2017. Following stage separation, SpaceX will attempt to recover Falcon 9’s first stage on the Of Course I Still Love You droneship, stationed just behind the horizon 28 km away in the Atlantic Ocean.

LZ-1 is still preoccupied with the aftermath of the Crew Dragon C204 test failure and subsequent destruction pending the NASA/FAA investigation.

The Dragon Payload

CRS-17 is the 17th commercial resupply mission, which was awarded to SpaceX in February of 2016. This is the fourth to last Commercial Resupply Mission with Dragon 1, and happens to be the 4th reuse of Dragon.

The Cargo Dragon C1133-2 is expected to arrive at the station ISS on Monday, May 6. Once it navigates into position, it will be captured by the Canadarm, and then berthed to the station a few hours later. NASA will provide a webcast of the arrival, capture and berthing.

In addition to the Cargo Dragons own 12 ton mass, there is added a total weight of the cargo of 2 482 kg (5 472 lb), consisting of 1 517 kg (3 344 lb) in the pressurized section and 965 kg in the unpressurized section. Cargo in the unpressurized section included the Orbiting Carbon Observatory 3 (OCO-3) and STP-H6.

After about 28 days Dragon will depart ISS, ditch its trunk, reenter the atmosphere and splash down in the Pacific Ocean during the day of June 3.

The return mass to Earth is 1905 kg ~ 4200 pounds as far it’s known.

SpaceX technicians open the side hatch of the Dragon vehicle and retrieve the time critical refrigerated items. The critical cargo was 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.
