China successfully sent a satellite for testing satellite internet technologies into space from a sea area near Yangjiang City, south China's Guangdong Province, on Wednesday. The satellite was launched by a Smart Dragon-3 (SD-3) rocket at 3:24 a.m. Beijing Time and has entered the preset orbit.

Developed by China Academy of Launch Vehicle Technology, the four-stage SD-3 rocket is a commercial rocket mainly for the satellite constellation networking market. It features high cost-efficiency, flexible launch mode and fast launch. Wednesday's launch was the second flight mission of the Smart Dragon rocket series after a maiden flight last December that sent 14 satellites into orbit.
