The 1,234-pound-pound (560-kilogram) satellites lifted off at 0323 GMT Wednesday (10:23 p.m. EST Tuesday) from the Taiyuan space center in northern China’s Shanxi province on top of a 13-story Long March 2D rocket, according to China’s state-run Xinhua news agency.

The launch occurred at 11:23 a.m. Beijing time, marking China’s 22nd attempted space launch of the year, and the 21st rocket mission to reach orbit.

China Launches High-resolution Remote Sensing Satellites

Two commercial Earth-imaging satellites launched by a Chinese Long March 2D booster Wednesday are flying in lower-than-planned orbits after an apparent rocket mishap, according to tracking data published by the U.S. military.

The two SuperView 1, or Gaojing 1, satellites are flying in egg-shaped orbits ranging from 133 miles (214 kilometers) to 325 miles (524 kilometers) in altitude at an inclination of 97.6 degrees.

The high-resolution Earth-observing platforms were supposed to go into a near-circular orbit around 300 miles (500 kilometers) above the planet to begin their eight-year missions collecting imagery for Siwei Star Co. Ltd., a subsidiary of China Aerospace Science and Technology Corp., a government-owned entity.

The SuperView 1 satellites are designed to collect optical black-and-white imagery with a resolution of less than 20 inches (about 50 centimeters), making them the highest-resolution civilian Earth-observing satellites launched by China.

The satellites can capture imagery in nearly 7.5-mile-wide (12-kilometer) swaths, turning to observe multiple locations on a single pass, or record images of the same point from multiple angles, allowing processors on the ground to generate stereo three-dimensional images.
