Notes:
Cost overruns soon forced NASA to consider other options for the International Space Station's habitation module. The space agency originally intended to use the same 8.2-meter long habitation module as the final 1991 Space Station Freedom design. In late 1998, NASA's Johnson Space Center proposed a much larger and lighter inflatable 8-meter diameter“Transhab” module that also could be converted into crew quarters for future manned missions to the Moon and Mars. It is also possible that the module will be built and paid for by private industry and leased to NASA, although the exact configuration isn't yet clear. Transhab and the 8.2-meter module appear to be equally expensive ($100 million in 1998) and NASA has not yet made a final decision.
