For more aspects of this, Scott Manley talked extensively about how Russia's invasion of Ukraine will have a large affect on the industry as a whole: https://youtu.be/1V-lj-jCqe8 https://youtu.be/1V-lj-jCqe8 Edit: TL;DR off the top of my head: - Lots of parts from Russia, some from Ukraine. Mostly in older designs that are planned to be phased out, but whose replacements aren't ready yet. - Russia can't really take their part of the ISS. All of the systems for moving the modules have been disabled, and they don't have the system to self sustain. At most they could disconnect and de-orbit it, as just a middle finger to the West. They are actively using the ISS for science and selling tourist seats, so it's unlikely they will want to abandon it. - Re-boosting the ISS is of notable but minor concern. Only Russia has the capability to do it right now. Another company is developing means to do so, but isn't ready yet. SpaceX's dragon could do it, but it would require a software update and the thrusters are poorly positioned so it'd be inefficient. However the ISS also has years before this would be a problem, so no major concern at this time, but developing the capability should be a top priority.
