Partners are committed to operating the International Space Station through 2024. After that, its fate is unclear.

The 20-year-old International Space Station (ISS) is showing its age: Last month, cosmonauts patched up cracks in a Russian module that were thought to be the source of minor air leaks. Cracks are also appearing in the international alliance that keeps the station going. This week, Russian Deputy Prime Minister Yury Borisov suggested Russia would back away from the ISS as early as 2025 to pursue a national space station.
