The big picture on China's space station that fell out of the sky
On Sunday night, Tiangong-1, China's first space station, crashed into the South Pacific Ocean, ending its 7-year orbit around the Earth. The 19,000-pound structure hasn't been visited by humans since 2013, and Beijing hasn't been able to communicate with it since 2016 — but its life and death tell the story of China's vision to conquer space.
The big picture: Tiangong-1 represented a slew of firsts for the Chinese space program. Its seven years among the stars were the culmination of the first phase of China's push to become an superpower in space.
