NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev sealed the Soyuz MS-28 hatch this weekend.
The closure marks the final stage of the crew's departure from the International Space Station (ISS). This process is critical for ensuring the spacecraft is pressurized and secure before it detaches from the station to begin its descent to Earth.
The crew spent approximately eight months [2] aboard the orbiting laboratory. This mission lasted a total of 241 days [1] for the three crew members before they prepared for their scheduled weekend undocking.
Williams and the two Russian cosmonauts worked to finalize the seal of the hatch, a procedure that separates the living quarters of the ISS from the return vehicle. The Soyuz MS-28 serves as both the transport and the lifeboat for the crew during their tenure in low Earth orbit.
Once the hatch is sealed and the crew is locked inside, the spacecraft undergoes a series of checks before the undocking mechanism is triggered. The return journey involves a series of burns to decelerate the craft and a descent through the atmosphere via parachutes.
The mission represents the continued collaboration between the U.S. and Russia in space exploration. Despite geopolitical tensions on the ground, the operational routines of the ISS remain a primary focus for both NASA and Roscosmos.
“The crew spent approximately eight months aboard the orbiting laboratory.”
The successful sealing of the Soyuz MS-28 hatch and the subsequent return of the crew underscores the operational stability of the International Space Station. By maintaining a rigorous rotation of astronauts and cosmonauts, NASA and Roscosmos ensure the station remains inhabited and functional, preserving a rare channel of international scientific cooperation.
