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

ISS slowly impacts tiny stray air particles slowing down ISS to lower orbits, which is why they reboost the stationMost likely those particles are Air & spent RCS
If you wanna Make a station that never loses orbit, you would have to make it extremely hig

That was cool

Anyone know how long they fire for and what is the total change in velocity?

why not getting the iss to a higher altitude so it doesnt have dran and need reboosting?

I'm aware the acceleration is tiny! But I'd love to try 'standing' on the back wall of Znity or Zarya as if it was extremely low gravity ;)

Would it be possible to move the station to a moon orbit with gentle boosts?

Super cool video!!!! "Nope, I'm not moving - You can see the smile on his face."

Here is another reboost video:

This was more impressive for me. Its nice to see the station accelerate "around" the lens :)

Btw: Seems located in the russian module ...
