State commission clears Soyuz rocket for mission to bring Russian cosmonauts back

The launch of the launch vehicle is scheduled for 03:24 Moscow time

MOSCOW, February 23. /TASS/. A state commission has ruled that the Soyuz-2.1a carrier rocket, which is to take the Soyuz MS-23 spacecraft to the orbit, is fit for the launch, and authorized its refueling, Russia’s state-run space corporation Roscosmos said on Thursday.

The spacecraft will return to the earth Russian cosmonauts Sergey Prokopyev and Dmitry Petelin, and NASA astronaut Frank Rubio.

"At the Baikonur Cosmodrome today, a state commission permitted refueling of the Soyuz-2.1a carrier rocket carrying the Soyuz MS-23 spacecraft, and authorized its launch from Pad 31 at 03:24:29 a.m. Moscow time," the Russian space agency said in a statement.

Approximately nine minutes after the launch, the spacecraft will separate from the upper stage of the rocket. Its docking with the Russian segment of the International Space Station (ISS) is scheduled for 04:01 Moscow time on February 26. It will be an uncrewed flight.

On December 15, 2022, the Soyuz MS-22 spacecraft docked to the orbital outpost experienced a coolant leak on its external radiator. After analyzing the situation, Russia’s state commission made a decision to bring the damaged Soyuz spacecraft back to Earth in crewless mode and return Roscosmos cosmonauts Sergey Prokopyev and Dmitry Petelin and NASA astronaut Frank Rubio, whose mission has been extended for several months, aboard the Soyuz MS-23 spacecraft. Initially, it was planned to send Soyuz MS-23 to space in mid-March, to take the next ISS mission to the orbital outpost.

Russian space industry specialists have carried out special investigations to find out that the Soyuz MS-22 was damaged by a sporadic micrometeoroid.
