One more launch! The Long March‑11, a four‑stage solid‑propellant rocket, successfully placed three satellites into orbit in a single mission! Sifang’s ultra‑light magnesium‑lithium alloy has once again delivered outstanding results!
At 10:29 on March 30, at China’s Jiuquan Satellite Launch Center, the Long March‑11 carrier rocket lifted off, deploying the Tianping‑2 A, B, and C satellites in a “one‑rocket‑three‑satellites” launch configuration. The satellites subsequently entered their designated orbits, marking a complete success for the mission.
At 10:29 on March 30, at China’s Jiuquan Satellite Launch Center, the Long March‑11 carrier rocket lifted off, deploying the Tianping‑2 A, B, and C satellites in a single launch. The satellites subsequently entered their designated orbits, marking a complete success for the mission.
The Long March‑11 rocket is a four‑stage solid‑propellant launch vehicle developed by the First Academy of China Aerospace Science and Technology Corporation. It employs a “three‑horizontal‑one‑vertical” cold‑launch configuration—horizontal docking, horizontal testing, horizontal transport, followed by full‑vehicle erection and vertical cold launch—and is primarily used to deploy spacecraft into sun‑synchronous and low‑Earth orbits.
This mission marks the inaugural flight of the new‑generation Long March‑11 rocket, featuring greater standardization across different orbital profiles and launch sites, as well as a higher degree of productization.
The Tianping‑2 A, B, and C satellites primarily provide services such as atmospheric and space environment measurements and orbit‑prediction model corrections.
With a single launch, the “Three Stars” mission saw the Tianping‑2 A, B, and C satellites extensively utilize Sifang’s ultra‑light magnesium‑lithium alloy, successfully reducing their mass to meet overall design specifications and achieving flawless insertion into their designated orbits. Once again, Sifang’s ultra‑light magnesium‑lithium alloy has delivered outstanding results!
