China launched a new remote sensing satellite using a Long March 4B launch vehicle from the Taiyuan Satellite Launch Center on Thursday. Launch of the Ziyuan-2D (Ziyuan-2 04) satellite took place around 4:30 UTC from the LC9 Launch Complex.
The launch returns the Long March 4 to flight after an issue with “structural resonance” between the third stage and the payload on a Long March 4C led to the loss of the Yaogan Weixing-33 mission on May 22.
Onboard were also the BNU-1 / Jingshi-1 satellite and the small Naxing-3 satellite.
The Ziyuan-2 (ZY-2) satellites are remote sensing vehicles capable of obtaining images and other data that can be used for planning, monitoring, crop yield monitoring and monitoring of natural disaster areas, as well as conducting field experiments in space sciences.
Information from various sources in China indicates that cameras aboard the Ziyuan-2 have a higher resolution than cameras used on the Ziyuan-1 / CBERS satellite launched in 1999. Ziyuan-2 vehicles are one of the largest satellites developed by China and its stabilization technology on its three space axes represented one of the biggest advances in Chinese space technology.
