astronauts arrive at the ISS in just three hours


The Soyuz MS-17 mission, which took off from the Baikonur cosmopolitan in Kazakhstan, at 2:45 am (Brasilia time) this Wednesday (14th) with astronauts Kate Rubins (USA), Sergey Ryzhikov and Sergey Kud-Sverchkov ( Russia), history: this is the last time that American astronauts will use a Russian rocket to go to the International Space Station (ISS).

The United States has been buying “seats” on Russian rockets since 2011, when the last of the space shuttles, Atlantis, was retired. But with the success of SpaceX’s Demo-2 mission, the country regained the ability to launch manned missions into space, using the Falcon 9 rocket and Crew Dragon capsule.

But there is another notable achievement on the MS-17: it was the first mission to test a new flight plan, which allows the capsule to dock ISS in just two orbits and three hours of travel, against the six hours of the old ” express route, “or the two days of the more conservative approach.

The Soyuz MS-17 joined ISS at 5:48 am (Brasília time), three hours and three minutes after the launch. Two hours later, after checking the capsule pressurization procedures to ensure that there is no air leakage into space, the astronauts joined Chris Cassidy (USA), Anatoli Ivanishin and Ivan Vagner (Russia) on board the station.

The next ISS manned mission will be Crew-1, already using a Falcon 9 rocket and the SpaceX Crew Dragon capsule. aboard will be astronauts Michael Hopkins, Victor Glover and Shannon Walker (USA), in addition to Japanese astronaut Soichi Noguchi. The launch is scheduled for October 31.
