A Soyuz-U launch vehicle (LV) carrying an unmanned supply spacecraft Progress M-12M was launched from the Baikonur launch site at scheduled time.
The purpose of the launch was to support further in-orbit operation of the International Space Station (ISS) in accordance with Russian commitments under the project.
The main objective of the mission was to deliver to the Space Station various cargoes for life support, systems and scientific equipment and propellant components that are needed to continue the ISS mission in manned mode and provide living and working conditions for the crew.
According to preliminary data, in the course of third stage operation 325 seconds into the flight of the LV, propulsion system malfunction was detected, and its emergency shut-down ensued. As a result the supply spacecraft did not reach its target orbit.
To investigate the accident, a commission has bee set up consisting of representatives from Roscosmos and organizations in the rocket and space industry.
- Currently working in orbit under the ISS program are: Russian cosmonauts Andrei Borisenko (crew commander), Alexander Samokutyaev and Sergei Volkov, US astronauts Ronald Garan, Michael Fossum and an astronaut of the Japanese space agency Satoshi Furukawa.
- Supply spacecraft Progress M-13M has been delivered to the launch site to undergo the last phase of testing and pre-launch processing.
