SpaceX CRS-28 mission patch  

SpaceX CRS-28, also known as SpX-28, is a Commercial Resupply Service mission to the International Space Station (ISS) launched on 5 June 2023.[1] The mission was contracted by NASA and flown by SpaceX using Cargo Dragon ship C208. It was the eighth flight for SpaceX under NASA's CRS Phase 2.[3]


ISS logistics

NASA contracted for the CRS-28 mission from SpaceX and therefore determines the primary payload, date of launch, and orbital parameters for the Cargo Dragon.[4][5]

ISS Roll Out Solar Arrays (iROSA)

See also: Roll Out Solar Array

Third pair of new solar arrays using XTJ Prime space solar cells. They were delivered to the station in the unpressurized trunk of the SpaceX Cargo Dragon spacecraft.[6]

The installation of these new solar arrays will require two spacewalks each: one to prepare the worksite with a modification kit and another to install the new panel.[7][8]

Mission details

The CRS-28 resupply mission was originally planned to launch on 4 June 2023, at 16:12:41 UTC. However, the countdown was stopped at T-01:49:08, and SpaceX scrubbed the mission and postponed it to the day after due to high winds in the recovery area. SpaceX announced, about 45 minutes afterward, the new T-0, planned for 15:47 UTC. The Falcon 9 rocket and the Cargo Dragon spacecraft lifted off at the new T-0, from the Kennedy Space Center's Space Launch Complex-39A. The first stage separation happened at T+02:38 and the Falcon 9 landed at T+09:05 on the A Shortfall of Gravitas droneship. At T+12:11, the Cargo Dragon separated from the second stage.

Dragon docked to the International Space Station's Harmony module on Tuesday, June 6, at 09:54 UTC.[11]

On June 7, SpaceX announced on Twitter that on the previous day, the Dragon 2 fleet as a whole had accumulated 1,324 days in orbit, surpassing the Space Shuttle program's total time in space. SpaceX also said that the mission was the 38th mission to ISS for Dragon 1 and 2 capsules, which exceeded the Shuttle's 37 ISS missions.[12]

Cargo Dragon C208 was undocked from the ISS on 29 June 2023 at 16:30 UTC. The capsule splashed down in the Atlantic Ocean on 30 June 2023 at 14:30 UTC, where it was retrieved by MV Shannon.
