A Kuaizhou 1A rocket failed to orbit the Jilin-1 Gaofen 02C optical remote-sensing satellite after liftoff from the Jiuquan Satellite Launch Center in northwest China on Saturday afternoon.
The official Xinhua news agency attributed the failure to the “abnormal performance” of the launch vehicle. An investigation has commenced.(more…)
A Chinese Long March 3B booster failed after launch on Thursday, destroying an Indonesian communications satellite and providing a spectacular nighttime light show for residents of Guam as debris burned up in the atmosphere.
China’s Xinhua news agency said the Long March 3B’s third stage malfunctioned after launch from the Xichang Satellite Launch Center.
The booster was carrying the Palapa-N1 geosynchronous communications satellite. The spacecraft was owned by Palapa Satelit Nusantara Sejahtera, which is a joint venture of Pasifik Satelit Nusantara and Indosat Ooredoo.
Palapa-N1, also known as Nusantara Dua, would have provided C-band and Ku-band broadcast and broadband services for Indonesia and neighboring regions. The China Academy of Space Technology built the spacecraft based on its DFH-4 platform.
Debris from the launch reentered the atmosphere near Guam. Officials said the debris posed no threat to the U.S. territory.
It was China’s second launch failure in less than a month. On March 16, the maiden launch of the Long March 7A rocket went awry, destroying a classified government satellite. Chinese officials have not announced the cause of the failure.
A Long March 7A booster failed after liftoff from the Wenchang Space Launch Center on Monday, destroying a new technology verification satellite known as Xinjishu Yanzheng-6.
Official Chinese news media acknowledged the failure of the new booster without providing any details concerning the loss. Very little is known about the lost payload.
Long March 7A is an upgraded version of the two-stage Long March 7 booster that was successfully launched two times in 2016 and 2017. Long March 7A employs a third stage powered by two cryogenic YF-75 engines that operate on liquid oxygen (LOX) and liquid hydrogen.
Long March 7A’s first two stages are powered by RP-1 and LOX. The rocket also includes four small strap-on boosters attached to the first stage.
The booster is designed to replace older models of Long March launchers that are powered by toxic hypergolic fuels.
