Beijing launched the first group of Yaogan-31 remote-sensing satellites into space at 04:25 GMT on Tuesday from Jiuquan Satellite Launch Center in northwestern China, Xinhua said. The satellites were carried by a Long March-4C rocket, the 271st mission of the Long March rocket family. The mission also sent a micro-nano technology experiment satellite into orbit, according to the report. The satellites are intended for electromagnetic environment surveys and other related technology tests. The first “Yaogan” series satellite, Yaogan-1, was launched in 2006.
