The Russian National Space Company said on the 21st that the Russian "Soyuz MS-22" spacecraft docked with the International Space Station on the same day, and two Russian astronauts and one American astronaut successfully entered the International Space Station. The Russian space company released a message on its official website the same day that the "Soyuz-2.1a" rocket carrying the "Soyuz MS-22" spacecraft lifted off from the Baikonur launch site in Kazakhstan at 16:54 Moscow time (21:54 Beijing time) on the 21st, and then entered the scheduled orbit. The Soyuz MS-22 spacecraft docked with the small test module "Dawn" of the Russian segment of the International Space Station at 20:06 Moscow time (1:06 Beijing time on the 22nd). The news said that the three astronauts who entered the International Space Station were Sergei Prokopiev and Dmitry Petrin from Russia and Francisco Rubio from the United States. They will work on the International Space Station for 188 days. This is the first cooperation between the Russian National Space Corporation and NASA since the signing of the "cross flight" agreement. On July 14 this year, the Russian National Space Corporation and NASA signed an agreement to cross use Russian "Alliance" spacecraft and American spacecraft to send astronauts from both sides to the International Space Station. The Russian space company said that the agreement would help promote cooperation within the framework of the International Space Station program and effectively implement projects to explore and use outer space for peaceful purposes.
