Yes, it can reboost the station. Dragon can't. Cygnus, Dreamchaser, and Soyuz can reboost. This matters because the station can't boost itself.

- BurningFrog 2y agoBoost as in push it to a different orbit?
- imglorp 2y agoYeah. The atmosphere is very thin but nonzero at ISS altitude so atmospheric drag causes orbital degradation over time. Whenever a resupply ship docks, if it has extra fuel, they orient the station so the ship is pointed prograde and fire the main thruster to increase the altitude. They plan to leave enough fuel for the supply ship to do its usual retro burn and land or burn up as normal. The station can also boost itself with the Zvezda module, which has thrusters. https://www.nasa.gov/international-space-station-frequently-asked-questions/#q6 https://www.nasa.gov/international-space-station-frequently-...
