The ISS has long been well above Earth's political squabbles. But since Russia invaded Ukraine, and most of the world began sanctioning Putin's regime, it seems less likely it will remain that way. On the station, Russian and American (and other countries') astronauts work together to research and problem solve. But on Earth, the head of Russia's space agency says the US will be to blame for the death of the space station.

Can The ISS even function without both sides cooperating? Does either side want it to, really? And with private companies like SpaceX pushing hard for increasing ISS access and work with space agencies—are we on the cusp of an entirely new era for humans in outer space?
