China announces second space station and crewed mission
China is preparing to place a second experimental space station into orbit this year, followed by a pair of astronauts who will dock with it and live on board for several days.
The government's China Manned Space Agency said the Tiangong 2 space lab would lift off some time after June.
The Shenzhou 11 spacecraft will follow shortly afterwards, the latest in a series of crewed Chinese missions that began in 2003.
Next year the Tianzhou 1 cargo ship will be launched to dock with the Tiangong 2 and provide it with fuel and other supplies.
China launched Tiangong 1, its first space station, in 2011 and plans to build a permanent station by 2022. China is planning a total of 20 space missions for this year.
