Update, March 24:  the undocking time has been updated to 5:57 am ET. NASA says it will land in Kazakhstan at 7:45 am ET (5:45 pm local time at the landing site). There will be no NASA TV coverage of the deorbit burn or landing. The ISS blog will be updated after the events occur.

Original Entry: As of March 12, 2023, the NASA TV schedule shows the Soyuz MS-22 spacecraft undocking from the International Space Station at 5:52 am ET.  NASA TV coverage will begin at 5:30 am ET.

Soyuz MS-22 delivered three crew members to the ISS (Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin and NASA astronaut Frank Rubio), but in December 2022 it experienced a coolant leak and is not considered safe to return all three of them to Earth because of thermal control issues.  A replacement spacecraft, Soyuz MS-23, was launched empty to bring them home later this year. Soyuz MS-22 will depart empty and is expected to land autonomously.
