Russia's space agency expects the International Space Station to stay in orbit through 2024, and plans to create its own space outpost with its segment of the station after that.
Roscosmos' scientific council concluded Tuesday that several Russian modules could eventually be undocked to "perform the task of ensuring Russia's guaranteed presence in space."
I really think it is time the international community made a note that Russia "does not play well with others" on their permanent record.
Let me just say that it would be wise if the people screening for volunteers to colonize Mars excluded ethnic Russians.
You never can tell when Putin might consider the red planet part of Cosmos Russia.
UPDATE: I did warn about this potential problem.
