http://www.spaceflightnow.com : New spy satellite launched by Long March rocket

Posted: August 10, 2010

A secret Chinese reconnaissance payload successfully launched on a Long March rocket Monday, the sixth time China has sent a satellite into orbit so far this year.

The tenth Yaogan mission lifted off aboard a Long March 4C rocket at 2249 GMT (6:49 p.m. EDT) from the Taiyuan launching center in northern China's Shanxi province. It was 6:49 a.m. local time at Taiyuan.

The three-stage booster placed the spacecraft in an orbit about 380 miles high with an inclination of 97.8 degrees, according to independent tracking data.

Despite the usual paranoia in the reporting about "spy satellite" "secret" and "reconnaissance payload" this is a civil earth observation satellite. A miltary mission would be secret, not televised, and the launch controllers would be in uniform not civilian dress.
