What's Next After the International Space Station?

$100 billion was spent building the International Space Station — including 42 different assembly flights, reports Recode. Yet "after two decades in orbit, the International Space Station will shut down," as NASA re-focuses on sending humans back to the moon. While they plan to keep it functioning as long as possible, NASA "has only technically certified the station's hardware until 2028 and has awarded more than $400 million to fund private replacements." (Which they estimate will save them $1 billion a year.) So then what happens?When these stations are ready, NASA will guide the ISS into the atmosphere, where it will burn up and disintegrate. At that point, anyone hoping to work in space will have to choose among several different outposts. That means countries won't just be using these new stations to strengthen their own national space programs, but as lucrative business ventures, too. "Commercial companies have the capability now to do this, and so we don't want to compete with that," Robyn Gatens, the director of the ISS, told Recode. "We want to transition lower-Earth orbit over to commercial companies so that the government and NASA can go use resources to do harder things in deep space." Private companies currently backed by NASA, including Lockheed Martin and Jeff Bezos's Blue Origin, could launch as many as four space stations into Earth's orbit over the next decade. NASA is also building a space station called Gateway near the moon; a SpaceX Falcon Heavy rocket carrying the living quarters for the station is scheduled to launch in 2024. Russia and India are planning to launch their own space stations to low-Earth orbit, too, and China's Tiangong station, which is currently under construction, already has astronauts living aboard... Russia may leave the ISS as soon as 2025, the same year its space agency, Roscosmos, plans to launch its new $5 billion space station. The European Space Agency, which represents 22 different European countries, is now training its astronauts for eventual missions to Tiangong... [C]ompetition for customers could get even more intense as space stations launched by China, Russia, and India open for business. Recode ultimately sees a future where private-sector customers choose from competing space stations — and even have to consider the political consequences of "favoring one nation's space station over another..." "In the best of scenarios, these new stations will learn from each other and massively expand scientific knowledge. But they will also make global politics a much bigger part of space, which could impact what happens here on Earth and how humanity explores the moon and Mars."
