YAOGAN 6
New Launch: 2009 April 22, 0255 UTC
Site: Taiyuan Space Center, PRC
Launcher: Long March 2C (Chang Zheng 2C)
International Designator(s): 2009-021A/SCC: 34839
China sent into orbit a clandestine remote sensing satellite Wednesday during a launch that was announced less than a day in advance.
A Long March 2C rocket blasted off at 0255 GMT Wednesday from the Taiyuan space base in northern China's Shanxi province. The two-stage booster, propelled by a noxious mix of hydrazine and nitrogen tetroxide, deftly guided the secret Yaogan 6 satellite into orbit, according to the official Xinhua news agency.
Tracking data indicate the rocket achieved a sun-synchronous orbit with an average altitude of about 300 miles [480 km].
China will use Yaogan 6 for land resource surveys, environmental surveillance, urban planning, crop yield estimates, disaster response, and space science experiments, Xinhua reported.
But Western analysts believe the spacecraft is actually a military reconnaissance satellite, possibly outfitted with a night-vision, cloud-piercing radar that can observe objects on the ground during darkness and all weather conditions.
The Yaogan series is likely a cover for a fleet of spy satellites carrying radars and digital optical observation equipment.
Yaogan satellites have been launched from Taiyuan and the Jiuquan space center.
