    The International Space Station got its start in 1998 when its first segments were launched, and it’s now starting to show its age.

    Since 2000, the ISS has continuously housed a rotating group of astronauts from 19 countries. The station has the only laboratory for long-duration microgravity research and has been instrumental in a number of scientific developments including creating more efficient water filtration systems and exploring new ways to treat diseases such as Alzheimer’s and cancer.

    “The International Space Station is currently approved to operate through at least December 2024 with our agreements with the international partners,” said Angela Hart, manager of the Commercial Low Earth Orbit Program Office at NASA. “However, as we are actively working to continue to do science and research, we understand that the ISS at some point will have its end of life.”

    Some of the long term, micro gravity effects on humans have given insights. There is a loss of bone calcium that has yet to be mitigated. It would be sad to send humans for an extended mission and their bones become mush when they return. Mapping the rate of calcium loss over time in microgravity would be useful.
