China launched a new three-person crew for its orbiting space station on Tuesday, with an eye to putting astronauts on the moon before the end of the decade.

The Shenzhou 16 spacecraft lifted off from the Jiuquan launch center on the edge of the Gobi Desert in northwestern China atop a Long March 2-F rocket just after 9:30 a.m. (0130 GMT) Tuesday.

The crew, including China’s first civilian astronaut, will overlap briefly with three now aboard the Tiangong station, who will then return to Earth after completing their six-month mission.

A third module was added to the station in November, and space program officials on Monday said they have plans to expand it, along with launching a crewed mission to the moon before 2030.

China built its own space station after it was excluded from the International Space Station, largely due to U.S. concerns over the Chinese space programs’ intimate ties with the People’s Liberation Army, the military branch of the ruling Communist Party.
