It has been nearly 27 years since International Space Station launch. Since it was launched many countries have set their bases in space by joining ISS. It has well served for scientists to experiment and research for years about the nature of space and living things react to living in space. With ISS we have explored and understood working space a lot. But now ISS is being too expensive to maintain. Also to keeping ISS orbiting around earth is hard as it keeps deorbiting faster than we thought. The space junk from our satellites and other debris have been increased in number. Thus being not very good for ISS to orbit with the damaging debris. So ISS is being planned to crash into ocean by 2030. NASA is planning to set up new space station to replace ISS before it is being crashed into ocean.
