Two satellites for technological experiments are sent into space by a Kuaizhou-1A, or KZ-1A, carrier rocket from Jiuquan Satellite Launch Center in northwest China's Gansu Province, on Aug. 31, 2019. The rocket blasted off at 7:41 a.m. and sent the two satellites into their planned orbit. Kuaizhou-1A, meaning speedy vessel, is a low-cost solid-fuel carrier rocket with high reliability and a short preparation period. The rocket, developed by a company under the China Aerospace Science and Industry Corporation, is mainly used to launch low-orbit microsatellites. Saturday's launch was the third mission of the KZ-1A rocket. (Photo by Wang Jiangbo/Xinhua)
