Russia May Be Planning National Space Station To Replace ISS

An anonymous reader writes with news that Russia may be building its own space station to replace the ISS. Russia may be planning to build a new, independent national space station rather than prolong its participation in the $150 billion International Space Station (ISS) program beyond its current 2020 end date. The U.S. space agency NASA proposed last year to extend the life of the ISS — the largest international project ever undertaken by nations during peacetime — beyond its currently scheduled 2020 end date to at least 2024.
