TAIYUAN, Sept. 8 (Xinhua) -- China successfully launched the Yaogan-21 remote sensing satellite into preset orbit at 11:22 a.m. on Monday Beijing Time (0322 GMT) from Taiyuan Satellite Launch Center.
Also launched in this mission was the Tiantuo-1 satellite, designed and built by the National University of Defense Technology and carried by Long March-4B rocket.
Yaogan-21 will be used for scientific experiments, natural resource survey, estimation of crop yield and disaster relief, while Tiantuo-1 was designed for smart satellite experiments.
The launch is the 193rd mission for the Long March rocket family.

Closing a four month gap since the previous orbital launch, China successfully launched the Yaogan Weixing-20 mission from the Jiuquan Satellite Launch Center. Launch took place on Saturday at 05:45 UTC from the 603 launch pad of the LC43 launch complex using a Long March-4C (Chang Zheng-4C) launch vehicle.
Chinese Launch:
The Yaogan Weixing-20 mission is composed of three satellites, with Chinese media referring to the new satellite as “a new remote sensing bird that will be used for scientific experiments, land survey, crop yield assessment, and disaster monitoring.”
As was the case in the last launches of the Yaogan Weixing series, Western analysts believe this class of satellites is being used for military purposes.
In particular this mission is similar to the Yaogan Weixing-9, Yaogan Weixing-16 and Yaogan Weixing-17, with three satellites flying in formation like a type of NOSS system.
Designed for locating and tracking foreign warships, the satellites will collect the optical and radio electronic signatures of the maritime vessels that will be used in conjunction with other information valuable for the Chinese maritime forces.
Yaogan-9 was launched on March 5, 2010, with Yaogan-16 bring was launched on November 25, 2012, and Yaogan-17 launched on September 1st, 2013.
This launch was the 202nd Chinese orbital launch and the 201st launch of the Long March launch vehicle family. It was also the 65th successful orbital launch from the Jiuquan Satellite launch Center.
