The flight was set to be the fourth for the Dragon C211 spacecraft. NASA’s cargo list also included toilet equipment, pre-treat quality sensors and a robotic tool for station maintenance, according to Bill Spetch, deputy manager of Commercial for NASA’s Low Earth Orbit Program.

Each Redwire solar-array wing is designed to generate more than 20 kilowatts for over 10 years after deployment.

Six Redwire-built wings have been deployed on the station since 2021, supporting astronaut and research operations. According to Redwire, those arrays have contributed to plans to operate the orbiting laboratory through 2030.

The Dragon spacecraft was planned to remain docked to the station for about a month. It also carried a clamshell apparatus intended to hold a failed Canadarm2 joint removed during a June 30 spacewalk.
