Each every now and then, the ISS requires a lift to counteract orbital decay and preserve its altitude. Whereas the ISS is supplied with its personal thrusters, they aren’t enough for main reboosts on account of restricted gas capability, decrease energy, and the necessity to protect onboard sources for different vital operations (like orientation management and area junk avoidance). So as an alternative, docked spacecraft are used to offer these exterior boosts. These spacecraft, particularly designed for such duties, carry their very own gas, minimizing the pressure on ISS sources, and have extra highly effective engines for enabling these substantial orbital changes.
All this mentioned, Russia’s Progress is at the moment the one spacecraft formally sanctioned for this activity, on account of its confirmed functionality and compatibility with the ISS. Whereas different spacecraft like Northrop Grumman’s Cygnus and Russia’s Zvezda could be adapted for reboost duties, they don’t seem to be sanctioned for this goal and would require further measures, equivalent to Progress having to gas Zvezda for the duty. NASA doesn’t love this example, which is why it has carried out reboost exams with Cygnus.
