China has launched its second space station Tiangong 2.
The Tiangong 2 was carried into space by Long March 7 rocket from the Jiuquan Satellite Launch Center on the edge of the Gobi Desert in northern China.
The station, whose name means “Heavenly Palace,” is considered a stepping stone to a mission to Mars by the end of the decade.
The Tiangong 2 module will be used for testing systems and processes for mid-term space stays and refueling, and will house experiments in medicine and various space-related technologies.
China’s first space station, Tiangong 1, was launched in September 2011 and officially went out of service earlier this year after having docked with three visiting spacecraft.
China conducted its first crewed space mission in 2003, becoming only the third country after Russia and the US to do so, and has since staged a spacewalk and landed its Yutu rover on the moon.
China’s space program plans a total of 20 missions this year. China is also developing the Long March 5 heavier-lift rocket needed to launch other components of the Tiangong 2 and other massive payloads.
China plans to land a rover on Mars by 2020, attempting to recreate the success of the US Viking 1 mission that landed a rover on the planet four decades ago.
