At 7:58 p.m. ESTEST is an abbreviation for Eastern Standard Time, the time zone for the eastern coast of the United States and Canada when observing standard time (autumn/winter). It is five hours behind Coordinated Universal Time.

The spacecraft launched at 7:24 p.m. EST on February 23 from the Baikonur Cosmodrome in Kazakhstan.

Soyuz is delivering 946 pounds of supplies to the International Space Station.

This new Soyuz will replace the Soyuz MS-22 spacecraft following a radiator coolant leak on December 14, 2022. The Soyuz MS-22 transported NASAEstablished in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion." NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin to the space station last September. The three crew members will return to Earth on the new Soyuz MS-23 later this year.

The damaged Soyuz MS-22 is scheduled to undock from the station in late March and return to Earth for an uncrewed parachute-assisted landing in Kazakhstan, and post-flight analysis by Roscosmos.

From 2011 when the Space Shuttle was retired to the 2020 demo flight of SpaceX Crew Dragon, the Soyuz spacecraft was the sole means of transporting crew to or from the International Space Station. Due to this, the Soyuz has continued to be heavily relied upon for these missions. Credit: NASA

The Soyuz is a type of spacecraft that was originally developed by the Soviet Union in the 1960s as part of the Vostok program for human spaceflight. Since then, it has been extensively used by both the Soviet and Russian space agencies for a wide range of missions, including transporting cosmonauts and astronauts to and from space stations like Mir and the International Space Station (ISS), launching robotic missions to other planets, and conducting scientific research in microgravity.

The Soyuz spacecraft consists of three modules: the orbital module, the descent module, and the service module. It is launched on top of a Soyuz rocket and returns to Earth via parachute landing in the steppes of Kazakhstan. Overall, the Soyuz has proven to be a reliable and versatile spacecraft, and continues to play an important role in human spaceflight today.
