China Launches Final Space Station Module
China launched its third and final space station module today, completing construction of Tiangong-3. It comes as China gets ready for its first crew rotation later this year, the beginning of China’s permanent human occupancy in Earth orbit. Coincidentally, the launch comes exactly 22 years after the first Russian-American crew launched to the International Space Station, which initiated permanent human occupancy in space for the ISS partners. China’s achievement may be two decades later, but is still a milestone for its growing space program.
