China launches Tianzhou 8 cargo mission to Tiangong space station

China sent fresh fuel and supplies to its space station today.

A Long March 7 rocket topped with the Tianzhou 8 cargo spacecraft launched from its pad at Wenchang Satellite Launch Center on Hainan island on Friday (Nov. 15) around 10:13 a.m. EST (1513 GMT; 11:13 p.m. Beijing time).

Tianzhou 8 will dock with the Tiangong space station a few hours after launch, delivering supplies for the Shenzhou 19 astronauts. Commander Cai Xuzhe, 48, and rookie astronauts Song Lingdong, 34, a former air force pilot, and Wang Haoze, also 34, China’s first female spaceflight engineer, arrived at the space station on Oct. 20.

The Tianzhou 8 mission will carry a number of science experiments as well as supplies for astronauts. One of the experiments aboard the spacecraft will involve bricks made from lunar soil simulant. These will be exposed to the harsh environment of space to see how suited they will be for building lunar habitats.

The bricks will be subjected to three years of exposure tests in space. They will be bombarded by ultraviolet light and cosmic rays and subjected to temperature differences. This will test the strength and durability of bricks in extreme environments and how the materials behave in the vacuum of space. China plans to build its International Lunar Research Station (ILRS) in the 2030s.

The cargo mission was due to launch ahead of Shenzhou 19, which lifted off Oct. 19 from Jiuquan in the Gobi Desert, but Tianzhou 8 launch preparations were hit by Typhoon Yagi, which passed over the Wenchang spaceport.(Space.com)
