China - Launch of Long March 7

People's Network just reported the succesful maiden flight of carrier rocket "Long March No.7" after its launch from Wenchang space center in Hainan province.


On June 25, at 20:00 local time, China's new carrier rocket "Long March No.7" had a flaming lift-off from Wenchang space launching site in Hainan [province]. After 603 seconds, the payload assembly successfully separated and entered an elliptic orbit with a minimum distance from Earth of 200 km [perigee] and a maximum distance of 394 km [apogee], such making the maiden launch of carrier rocket "Long March No.7" a complete success.

Technical information from other sources:

The Long March 7 is the medium-lift variant of a new generation rocket family that includes the heavier-lift Long March 5 and the small-mid cargo Long March 6. The structure is based on the reliable, man-rated Long March 2F rocket. It inherited the 3.35m-diameter core stage and 2.25m-diameter liquid rocket boosters. Where the earlier Long March 2 rocket family used expensive and dangerous N2O4/UDMH propellants, the Long March 7 uses LOX/kerosene. The engines are shared with the Long March 5 and 6. The goal was to build a more cost-effective and less hazardous rocket family to replace today's Long March 2 and eventually the Long March 3. It will be capable of placing a 5,500 kilograms (12,100 lb) payload into a sun-synchronous orbit.
