The International Space Station can’t stay up there forever. Eventually it will be deorbited and crash into the southern Pacific Ocean.
The first module of the ISS, Zarya, was launched on 20 November 1998 on a Russian Proton rocket and continued construction through 2011.
The station has been approved to operate through 2024, and will likely pass another structural analysis allowing it to remain in orbit through 2028. But experts have expressed concern about extending that timeline any further.
