Inflatable space stations: Roscosmos has asked the Russian government for RUB16bn towards the development of inflatable space station modules as part of its 2016-2025 federal space program. Inflatable modules have already been developed and tested by the US-based Bigelow Aerospace and Roscosmos now wants to build its own version which would have a five-year life expectancy, would include a pressurised compartment volume of 300m3 and would be ready for launch by 2021.
