Summary

This NASA live broadcast documents the departure of three crew members from the International Space Station (ISS) aboard the Soyuz MS-28 spacecraft. The video begins with the crew saying farewell to their colleagues, including a formal change of command ceremony where Roscosmos cosmonaut Sergey Kud-Sverchkov hands over station command to NASA astronaut Jessica Meir. The crew then boards the Soyuz, and the hatch is closed. The broadcast provides detailed explanations of the Soyuz spacecraft’s three modules, the undocking procedure, the deorbit burn, and the landing sequence. It includes live views from inside the station and the flight control room, with commentary from NASA’s Leah Cheshier. Key milestones are highlighted: undocking at 2:03 a.m. CDT, deorbit burn at 4:31 a.m., and landing in Kazakhstan at 5:25 a.m. The crew, having spent 241 days in space, completes 3,856 orbits and travels over 102 million miles. The broadcast emphasizes the collaborative nature of spaceflight and the teamwork involved in the mission.
