China successfully launched a Long March 2D rocket July 29 with a Tianhui military satellite on a mission to collect data for maps and land surveys.
China’s largest state-owned space program contractor said the Tianhui 1-04 satellite launched at 0401 GMT (12:01 a.m. EDT) on July 29 from the Jiuquan space center in the Gobi Desert of northwestern China.
The 13-story Long March 2D rocket fired off its launch pad with around 650,000 pounds of thrust from four hydrazine-fueled main engines. The Long March 2D’s second stage took over a few minutes after liftoff, completing a burn to inject its payload into orbit.
Chinese officials declared the launch a success, and independent orbital tracking data published by the U.S. military indicated the rocket deployed its satellite in a near-circular orbit about 300 miles (500 kilometers) above Earth at an inclination of 97.5 degrees.
The Tianhui 1-04 payload is the sixth in China’s series of Tianhui mapping satellites, joining three similar first-generation spacecraft and two new-generation Tianhui satellites.
