After President Joe Biden announced new sanctions Thursday that "will degrade their (Russia's) aerospace industry, including their space program," Roscosmos Director General Dmitry Rogozin said on Twitter that the station's orbit and location in space are controlled by Russian engines."If you block cooperation with us, who will save the International Space Station (ISS) from an uncontrolled deorbit and fall into the United States or...Europe?" Rogozin said. "There is also the possibility of a 500-ton structure falling on India and China. Do you want to threaten them with such a prospect? The ISS does not fly over Russia, therefore all the risks are yours. Are you ready for them?"

There are obvious issues after the Russian invasion of Ukraine with continued cooperation with Russia on the ISS and possible alternatives.
Here's a hardware-centric thread that about how this could work. The idea is to remove the Russian segment, attach an additional IDA to PMA-1 in its place, and semi-permanently dock a Dragon (or Cygnus upgraded to dock instead of berth) there to provide reboosts.I'd say "sounds crazy", except Chris Bergin and Elon Musk were both giving this thread their thumbs-up on Twitter, so it's worth discussing at least.(Let's all please direct any talk of Why and Whether to the Space Policy section, and keep this focused on the How.)https://twitter.com/Space_Pete/status/1497029449455312901

But I registered just to react to this. Has Elon Musk really trolled this guy by suggesting that SpaceX would take on the challenge if needed?!?!I find hilarious and mind blowing, but not being an English native speaker, I'm afraid I'm reading it wrong 😅

Do SpaceX still have some Dragon 1s available in storage? Would that do the job?

Would that do the job?Dragon 1 berths with the CBM, as does Cygnus, so they couldn't go in this spot in this scheme. Dragon 2 (both crewed and cargo) use the IDA, as does Starliner.For this, either you'd want to put additional fuel and thrusters in the Dragon 2 trunk, or you'd want to modify Cygnus to dock with an IDA. Neither is a simple ask.Note the current Cygnus mission is already planning to do a reboost from the CBM. I am not sure how much of a boost it's expected to give, or what the pros and cons of doing it from that node are, or how long-term viable that would be. There's also the question of what launcher Cygnus would use in this scenario. https://spaceflightnow.com/2022/02/21/northrop-grumman-delivers-cargo-and-new-reboost-capability-to-space-station/
. The HALO part of the PPE-HALO launch on Falcon Heavy is Cygnus-derived, so at least some of that qualification work to put a Cygnus on a Falcon may be shared and/or already underway.
Why not use a Starship instead of a Dragon or a Cygnus.Like the HLS one which docks nose first for the Lunar mission with Orion.

Metholox boils off to quickly. You would need 4 or 5 Tanker Flights get Starship to the ISS. Then a dedicated Tanker to refuel the permanent attachment. It really is easier to start over with Axiom Station.
A Starship is 2 millions per flight. With 24 million a year you can have another one every month
If boil off was such an issue how would the Mars landing work after nine month of transit from Earth
