Video clip of ESA astronaut Matthias Maurer and his Expedition 66 crewmates experiencing a reboost of the Worldwide Area Station. Whereas the video on the backside of this text is sped up by 8 instances, this GIF is sped up by 32 instances.
That is paying homage to happening a slide on the playground – after which instantly getting again in line to go down once more. Besides in area.
Right here’s what it seems to be like on board the Worldwide Area Station when thrusters fireplace for an orbital reboost. Whereas it looks as if the astronauts are shifting contained in the station, in actuality it's the Area Station that's shifting round them. And essentially, the acceleration doesn’t occur this quick – the video is sped up eight instances (GIF on prime is sped up 32 instances). However it nonetheless seems to be like enjoyable!
The information for the acceleration charge/change for this specific burn was not accessible, however for a earlier burn with a length of 12 minutes, 17 seconds had a Delta-V of 1.34 meters/second (4.4 toes/second).
The crew seen right here is Expedition 66, which incorporates NASA astronauts Raja Chari, Thomas Marshburn Kayla Barron, and Mark Vande Hei; ESA (European Area Company) astronaut Matthias Maurer; Roscosmos cosmonauts Anton Shkaplerov and Pyotr Dubrov.

The astronauts are clearly having fun with the expertise. It should really feel considerably just like when a automobile or airplane accelerates – it looks like you might be being pushed again into the seat, when in actuality, the seat is being pushed into you by the acceleration of the automobile.
The ISS often orbits about 400 km (250 miles) above the Earth. However the results of atmospheric drag may cause the station to lose as a lot as 100 meters a day in altitude. Due to this fact, common reboosts are required, often about as soon as a month. There’s no actual schedule for when a reboost is completed, because the density of Earth’s ambiance at these altitudes consistently adjustments, relying on how a lot vitality is being fed into it by the Solar. Due to this fact, the orbital decay charge will not be constant. However the ISS orbits decays quicker than different satellites at an analogous altitude on account of its huge dimension and floor space.
The Worldwide Area Station is pictured from the SpaceX Crew Dragon Endeavour throughout a fly round of the orbiting lab that befell following its undocking from the Concord module’s space-facing port on November 8, 2021. The orbital complicated was flying 263 miles above the Marshall Islands within the Pacific Ocean when this photograph was taken. Credit score: NASA
Reboosts are additionally completed to optimize the ISS’s orbital place for future visiting autos arriving on the station. This specific reboost was carried out in March 2022 utilizing Russia’s ISS Progress 79 cargo craft. By firing its engines for a number of minutes, the station was put on the correct altitude for an arriving Soyuz for the brand new crew members that arrived in March.
NASA says that every one ISS propulsion is offered by the Russian Section and Progress cargo spacecraft. Propulsion is used for station reboost, angle management, particles avoidance maneuvers (in addition to eventual deorbit operations). The U.S. gyroscopes present day-to-day angle management, i.e. controlling the orientation of the station. Russian thrusters are used for angle management throughout dynamic occasions like spacecraft docking, they usually present angle management restoration when the gyroscopes attain their management limits.
Northrop Grumman’s Cygnus is the one U.S. industrial spacecraft at the moment accessible to supply reboosts, though it's nonetheless at the moment in testing mode. The primary Cygnus able to performing reboosts arrived on the ISS in February 2022.
