The ISS orbits at an altitude of about 400 km, but the ISS gradually slows down due to slight atmospheric resistance and the altitude drops.Reboost to correct orbit using the engine of a supply ship(Orbit climbing) is carried out regularly. Also,Orbit change to avoid collision with space debris(Debris avoidance maneuver) may be performed.

According to Russian state-owned space company Roscosmos, the Progress MS-14 moored at the end of the ISS has been moored for a year.Inject the engine 10 timesAndISS orbit correctionThe we.Two of these were unplanned orbital changes to avoid space debrisIt is said that it was.

369 days including solo flightThe flight period of the Progress MS-14 exceeded the 337 days established in 1993 by the supply ship “Progress M-17” that carried supplies to the “Mir” space station at that time.Set the longest flight period record for Russian supply vesselsIt was decided to do.

On April 28, when Progress MS-14 left the ISS, the Japan Aerospace Exploration Agency (JAXA)Soichi Noguchi, 4 astronauts, etc.Manned spacecraft on board“Crew Dragon”The first operation unit was also scheduled to leave the ISS, but it was postponed due to the weather in the area where the water was scheduled to land.After that, the crew dragon carrying Astronaut Noguchi and othersHe left the ISS at 9:35 on May 2, 2021 Japan time, and landed on the planned sea area off Florida at 15:56 on the same day.And are returning to Earth.
