When the International Space Station is given a reboost, how many burns are performed? Is it a Hohmann transfer orbit, with one perigee burn and one apogee burn? Or is it one burn at apogee just to raise the perigee? Something else?

    $\begingroup$ In more ways than one, a question for Hohmannfan. $\endgroup$ – DrSheldon Apr 27 at 21:35
  • $\begingroup$ This has always bothered me. If it was a complete one-orbit 92 minute burn I would have assumed that it's a spiral outwards to a larger circle, but I think they are only like 20 to 40 minutes long. Interesting! $\endgroup$ – uhoh Apr 28 at 1:20

    $\begingroup$ Not an expert, but I doubt they care about Hohmann. Boosts happen so often and they only are a few m/s and last somewhere around a third to half an orbit, so no advantages from Oberth effect. There's a related answer with links that I think covers it well: space.stackexchange.com/questions/9087/…. $\endgroup$ – user40414 Apr 28 at 11:57
