HELSINKI — China launched a Lengthy March 11 stable rocket from Xichang early Friday, finishing a marketing campaign of seven orbit launch makes an attempt in simply over per week which included the debut of two new launch automobiles.
The Lengthy March 11 rocket lifted off at 1:17 a.m. Jap (0617 UTC) Dec. 16, sending the Shiyan-21 satellite tv for pc into orbit. The China Aerospace Science and Know-how Company (CASC) announced launch success lower than half-hour after liftoff.
Little was revealed in regards to the Shiyan-21 satellite tv for pc, with CASC stating solely that it was developed by its subsidiary, the Shanghai Academy of Spaceflight Know-how (SAST).
Shiyan sequence satellites are believed for use to pilot new applied sciences in house. State media Xinhua reported that the newly launched satellite tv for pc shall be used for “in-orbit verification of recent house applied sciences,” including that Shiyan means “experiment” in Chinese language.
The launcher was offered by the China Academy of Launch Car Know-how (CALT), one other main entity below CASC.
The mission marked the fifteenth launch of the 20.8-meter-long, 2-meter-diameter and 58-metric-ton four-stage stable Lengthy March 11. Of those, 11 have taken place at nationwide spaceports Jiuquan and Xichang, with 4 extra performed from converted barges out on the Yellow Sea. The Lengthy March 11 makes use of a chilly launch system, which sees it expelled from its canister earlier than igniting.

The launch additionally accomplished a flurry of seven Chinese language launches throughout slightly greater than 9 days, and simply 36 hours after the earlier launch from Xichang, which noticed a hypergolic Lengthy March 2D rocket launch a fourth group of three Yaogan-36 reconnaissance satellites.
The extraordinary interval of launch exercise kicked off at 0115 UTC Dec. 7 at Jiuquan, seeing a profitable second flight of the Kuaizhou-11 rocket for CASC sister group CASIC, greater than two years after the failure of the primary launch. The launch put the VHF Information Change System (VDES) check satellite tv for pc into orbit as a part of the Xingyun constellation.
The path to operational standing for Kuaizhou-11 may additionally have been hindered by an explosion at a CASIC web site at Jiuquan.
This was adopted by the launch Dec. 8 of the Gaofen-5 (01A) hyperspectral imaging satellite tv for pc on a Lengthy March 2D from Taiyuan, north China, with the first launch of the Jielong-3 stable rocket from a transformed barge within the Yellow Sea 12 hours later.
Launches of the Shiyan-20 A and B satellites on a Lengthy March 4C and Zhuque-2, a failed try by personal agency Landspace to develop into the primary to fly a methane-fueled rocket to orbit, occurred at Jiuquan on Dec. 12 and 14 respectively.
The launches imply China has launched 62 occasions this 12 months and already surpassed its nationwide document of launches in a calendar 12 months, 55, set in 2021. China’s prior document had been 39 launches, reached in each 2018 and 2020.
51 of those launches have been Lengthy March launches performed by CASC, all efficiently. The Jielong-3, Kuiazhou-11 and Zhuque-2 are among the many 11 non-Lengthy March rockets launching from China this 12 months, together with 4 launches of the smaller Kuaizhou-1A, the debut of the ZK-1A from the Chinese language Academy of Sciences, a third consecutive failure of iSpace’s Hyperbola-1 and two launches of Galactic Energy’s Ceres-1 stable rocket.
CASC acknowledged early within the 12 months that it supposed to launch more than 50 times in 2022, together with a sequence of missions to complete the Tiangong house station.
At press time, the U.S. had performed 82 launches to this point in 2022, together with Rocket Lab Electron launches. SpaceX’s Falcon 9 accounts for 55 of those, and one other pair scheduled for later Dec. 16.
