    International Space Station reboost | Cosmic Kiss

    Get in line with ESA astronaut Matthias Maurer and his Expedition 66 crew mates to experience a reboost of the International Space Station from the inside. This video is sped up 8 times fast.

    The International Space Station flies around Earth at around 400 km. It is reboosted periodically to maintain its orbit and overcome the effects of atmospheric drag created by molecules of the atmosphere, which causes the Station to lose about 100 m of altitude per day.

    A Space Station reboost maneuver also optimizes phasing for future visiting vehicles arriving at the station. In March 2022 the ISS performed a reboost using Russia’s ISS Progress 79 cargo craft. By firing its engines for several minutes, the station was put at the proper altitude for a crew ship orbit rendezvous and landing operations.

    During the manoeuvre, the astronauts inside the station keep flying at the same speed and direction. While it seems like the astronauts are moving inside the station, it is in fact the ISS that gets the boost and is moving around them.

  • ISS reboost

    ISS reboost

    Ever wondered what happens inside the International Space Station during a reboost? ESA astronaut Tim Peake filmed inside during last week’s firing of the Progress thrusters.

    Even at 400 km, there are still enough molecules of the atmosphere to create some ‘atmospheric drag’, which causes the Station to drop by about 2 km a month. Because of this we need to raise the Station’s orbit every so often. On 17 February the engines of the Progress M-29M spacecraft that is docked to the aft port of the Zvezda module were fired for 11 minutes.

    The burn primarily focused on raising the Station’s perigee, making the orbit more circular.

    Pre-reboost: 398.2 x 407.4 km – inclination 51.64° – Period: 92.62min
    Post-reboost: 402.1 x 406.9 km – inclination 51.64° – Period: 92.66min
