  Well, Russians are thrifty.

MOSCOW — 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." The space station, run by the United States, Russia, Japan, Canada and the European Space Agency, is set to remain operational at least through 2024. Russia's own Mir space station was deorbited in 2001 after 15 years as Moscow sought to concentrate its resources on the International Space Station.

Russia's space agency also said it plans to launch manned missions to the moon around 2030, but gave no further details.

I like to think that NASA would be equally thrifty.
The cost per ounce for new components is, well, nearly astronomical: better to make do with what there is already there.
