Russian Federal Space Agency (ROSCOSMOS)
Countdown to launch

This Soyuz 2.1a mission by Russian Federal Space Agency (ROSCOSMOS) is scheduled to launch from Baikonur Cosmodrome, Republic of Kazakhstan. This human exploration mission targets Low Earth Orbit. The Soyuz rocket family has been instrumental in modern space access, representing decades of engineering refinement in propulsion, guidance systems, and structural design.
Every rocket launch involves precise coordination between the launch vehicle, payload, ground systems, and range safety. The launch window is carefully calculated based on orbital mechanics — for missions targeting the International Space Station, the window may be only seconds long, while interplanetary missions can have windows lasting weeks. Weather conditions, including upper-level winds, lightning risk, and cloud ceiling, are monitored up until the final moments before ignition. Space weather conditions from solar activity can also affect launch decisions, as high radiation levels may pose risks to satellite electronics.

Soyuz MS-29 will carry three cosmonauts and one astronaut to the International Space Station aboard the Soyuz spacecraft from the Baikonur Cosmodrome in Kazakhstan. The crew consists of Roscosmos cosmonauts Pyotr Dubrov and Anna Kikina, as well as NASA astronaut Anil Menon.

Soyuz
The Soyuz programme is a human spaceflight programme initiated by the Soviet Union in the early 1960s. The Soyuz spacecraft was originally part of a Moon landing project intended to put a Soviet cosmonaut on the Moon. It was the third Soviet human spaceflight programme after the Vostok and Voskhod programmes.
International Space Station
The International Space Station programme is tied together by a complex set of legal, political and financial agreements between the sixteen nations involved in the project, governing ownership of the various components, rights to crewing and utilization, and responsibilities for crew rotation and resupply of the International Space Station. It was conceived in 1984 by President Ronald Reagan, during the Space Station Freedom project as it was originally called.
