Two Chinese rocket launches hours apart Friday successfully deployed a radio and TV broadcasting spacecraft and an atmospheric environmental monitoring satellite.

The missions from different spaceports lifted off a little more than six hours apart, continuing China’s 2022 launch campaign, a schedule highlighted by planned flights to expand the country’s space station.

A Long March 3B rocket lifted off from the Xichang launch base in Sichuan province at 1200 GMT (8 a.m. EDT; 8 p.m. Beijing time) Friday with the Chinasat 6D, or Zhongxing 6D, communications satellite. The 18-story-tall launcher steered southeast from Xichang, nestled in a hilly region of southwestern China, and shed its four liquid-fueled boosters and core stage about two-and-a-half minutes into the mission.

A second stage and hydrogen-fueled third stage delivered the Chinasat 6D satellite into an elongated geostationary transfer orbit stretching more than 22,000 miles (nearly 36,000 kilometers) above Earth at its highest point, with an inclination of 28.5 degrees to the equator, according to publicly-available U.S. military tracking data. (...)

Chinasat 6D, designed for a mission of more than 15 years, will replace the Chinasat 6A satellite launched in 2010.

A small satellite launcher developed by the Chinese startup iSpace failed to place its Earth observing payload into orbit Friday, the third consecutive failure for the company’s Hyperbola 1 rocket. (...)

The payload on Friday’s failed launch was believed to be a high-resolution Earth-imaging satellite for the Chinese Jilin 1 remote sensing constellation.

The Hyperbola 1 rocket — also called the SQX-1 — is a four-stage rocket capable of deploying a payload of up to 660 pounds, or 300 kilograms, to a 310-mile-high (500-kilometer) sun-synchronous orbit, according to iSpace. The Hyperbola 1 stands approximately 78 feet (24 meters) tall, and produces about 173,000 pounds of liftoff thrust.

Enabled by a policy change in 2014 to permit the flow of private capital in China’s launch industry, companies like iSpace established in the last few years have quickly fielded small solid-fueled launchers. Many, or all, of the first generation of privately-funded Chinese launchers appear to use rocket motors derived from Chinese ballistic missiles. (...)
