China breaks ground on space launch center

China broke ground on its fourth space center Monday, highlighting the country's soaring space ambitions six years after it sent its first man into orbit.

The space port on the southern island province of Hainan incorporates a launch site and mission control center for slinging the country's massive new rockets into space carrying satellites and components for a future space station and deep space exploration.

The reports portrayed the center as a major stride forward for China's military-backed space program, which has launched three manned missions since 2003, including one last year that featured the country's first space walk.

China's future space ambitions include building an orbiting station and sending a mission to the moon, putting it in the forefront of the tightening Asian space race involving India, Japan and South Korea. China says its space program is purely for peaceful ends, although its military background and Beijing's development of anti-satellite weapons have prompted some to question that.

The Hainan center, located near the town of Wenchang and slated to go into use in 2013, is located at a latitude of about 19 degrees north, far closer to the equator than China's other bases in the its southwest and northern plains.

Proximity to the equator is an advantage for launching payloads such as geostationary satellites used for telecommunications because less fuel propellant is needed. Reports said rockets launched from the Hainan base will be capable of carrying up to 14 percent more payload than those launched from Jiuquan, the home of the manned space program in northern China.

That added capacity should aid particularly in China's space station program as well as plans to assemble the Beidou, or "Compass," navigation system as an alternative to the U.S. satellite GPS network, the dominant positioning system.
