China launches longest manned space mission

China launched its longest manned space mission on Monday, sending two astronauts into orbit to spend a month aboard an space laboratory that is part of a broader plan to have a permanent manned space station in service around 2022. The astronauts will dock with the Tiangong 2 space laboratory, or "Heavenly Palace 2", which was sent into space last month. It will be the longest stay in space by Chinese astronauts, state media reported.
