The data for the acceleration rate/change for this particular burn was not readily available, however for a previous burn with a duration of 12 minutes, 17 seconds had a Delta-V of 1.34 meters/second (4.4 feet/second).
The crew seen here is Expedition 66, which consists of NASA astronauts Raja Chari, Thomas Marshburn Kayla Barron, and Mark Vande Hei; ESA (European Space Agency) astronaut Matthias Maurer; Roscosmos cosmonauts Anton Shkaplerov and Pyotr Dubrov.

The astronauts are certainly taking pleasure in the experience. It must feel rather comparable to when a vehicle or plane accelerates– it seems like you are being pushed back into the seat, when in truth, the seat is being pressed into you by the acceleration of the vehicle.
The ISS normally orbits about 400 km (250 miles) above the Earth. But the impacts of atmospheric drag can cause the station to lose as much as 100 meters a day in altitude. For that reason, regular reboosts are needed, normally about once a month. Theres no genuine schedule for when a reboost is done, as the density of Earths atmosphere at those elevations continuously changes, depending on just how much energy is being fed into it by the Sun. Therefore, the orbital decay rate is not constant. But the ISS orbits decomposes faster than other satellites at a comparable altitude due to its massive size and area.
The International Space Station is envisioned from the SpaceX Crew Dragon Endeavour during a fly around of the orbiting laboratory that happened following its undocking from the Harmony modules space-facing port on November 8, 2021. The orbital complex was flying 263 miles above the Marshall Islands in the Pacific Ocean when this picture was taken. Credit: NASA
Reboosts are also done to optimize the ISSs orbital position for future checking out cars coming to the station. This specific reboost was carried out in March 2022 using Russias ISS Progress 79 cargo craft. By shooting its engines for a number of minutes, the station was put at the correct elevation for a showing up Soyuz for the new team members that arrived in March.
NASA says that all ISS propulsion is provided by the Russian Segment and Progress freight spacecraft. Propulsion is used for station reboost, mindset control, debris avoidance maneuvers (as well as ultimate deorbit operations). The U.S. gyroscopes provide day-to-day attitude control, i.e. controlling the orientation of the station. Russian thrusters are utilized for mindset control during vibrant events like spacecraft docking, and they provide mindset control healing when the gyroscopes reach their control limitations.
Northrop Grummans Cygnus is the only U.S. business spacecraft presently offered to provide reboosts, although it is still currently in testing mode. The very first Cygnus capable of carrying out reboosts came to the ISS in February 2022.

Heres what it looks like on board the International Space Station when thrusters fire for an orbital reboost. While it appears like the astronauts are moving inside the station, in truth it is the Space Station that is moving around them. The International Space Station is pictured from the SpaceX Crew Dragon Endeavour throughout a fly around of the orbiting laboratory that took location following its undocking from the Harmony modules space-facing port on November 8, 2021. Reboosts are likewise done to enhance the ISSs orbital position for future visiting lorries arriving at the station. Propulsion is used for station reboost, attitude control, particles avoidance maneuvers (as well as ultimate deorbit operations).
Video clip of ESA astronaut Matthias Maurer and his Expedition 66 crewmates experiencing a reboost of the International Space Station. While the video at the bottom of this article is accelerated by 8 times, this GIF is sped up by 32 times.
This is reminiscent of decreasing a slide on the play area– and then instantly returning in line to decrease once again. Other than in space.
