Soyuz

The uncrewed Soyuz MS-22 spacecraft is scheduled to undock from the station on 2023-03-28.

Roscosmos launched an uncrewed Soyuz spacecraft, Soyuz MS-23, in February to replace Soyuz MS-22.

Soyuz MS-23 launched two days before 2023-02-25 on a Soyuz-2.1a rocket from the Baikonur Cosmodrome in Kazakhstan.

The uncrewed Soyuz MS-23 spacecraft arrived at the International Space Station on 2023-02-25.

Roscosmos and NASA decided in January that Soyuz MS-23 would launch without a crew in February.

Roscosmos is planning an uncrewed Soyuz MS-23 launch on a Soyuz-2.1a rocket to replace the damaged Soyuz MS-22, with launch scheduled for 2023-02-23 at 7:24 p.m. Eastern.

Soyuz MS-23 is scheduled to dock with the International Space Station two days after its 2023-02-23 launch.

Soyuz MS-23 will launch without a crew because a coolant leak in the Soyuz MS-22 spacecraft in December rendered Soyuz MS-22 unable to safely return its three-person crew.

The scheduled docking of Soyuz MS-23 is set to occur shortly before the arrival of the SpaceX Crew-6 mission currently scheduled to launch early 2023-02-26.

The council of designers at RSC Energia recommended on 2023-02-18 that a Soyuz-2.1a launch of the Soyuz MS-23 spacecraft take place at 7:32 p.m. Eastern on 2023-02-23.

Soyuz MS-23 is scheduled to dock with the International Space Station two days after its planned 2023-02-23 launch.

Roscosmos delayed the uncrewed Soyuz MS-23 launch to investigate a coolant leak in the Progress MS-21 cargo spacecraft reported on 2023-02-11.

Yuri Borisov, head of Roscosmos, posted on the agency’s Telegram account on 2023-02-13 that the launch of the Soyuz MS-23 spacecraft scheduled for late 2023-02-19 (2023-02-20 at the Baikonur Cosmodrome) would be delayed until early March.

Roscosmos released on 2023-02-13 a close-up image of the location of the Soyuz MS-22 leak taken by a camera on the Canadarm2 robotic arm.

Roscosmos, in conjunction with NASA and other ISS partners, decided in January to launch Soyuz MS-23 without a crew to replace Soyuz MS-22.

Soyuz MS-22 launched to the International Space Station in September 2023, a little more than a month before the Progress MS-21 launch.

The Soyuz MS-22 coolant leak prompted Roscosmos and ISS partners to launch the next Soyuz spacecraft to the station without a crew.

Soyuz MS-23 is scheduled to launch on 2024-02-20 and dock with the International Space Station on 2024-02-22.
