At 12:15 on May 21st, the Kuaizhou-11 solid carrier rocket ignited and lifted off from the Jiuquan Satellite Launch Center, successfully placing four satellites into their designated orbits, marking a perfect success for the launch mission.
The four satellites launched this time are: Wuhan-1 satellite, ultra-low orbit technology test satellite, Tianyan-22 satellite, and Lingque-3 01 satellite.
This marks the 32nd flight of the Kuaizhou series carrier rockets.
The Kuaizhou-11 solid carrier rocket, developed by the China Aerospace Science and Industry Corporation's Sanjiang Space Group, features mobile launch capabilities, enabling it to deploy multiple satellites for a variety of commercial missions. With launch costs kept below $10,000 per kilogram, it is China's most powerful carrier rocket in terms of payload capacity, liftoff mass, and diameter, with a liftoff mass of 78 tons, a diameter of 2.2 meters, a maximum payload capacity to low Earth orbit of 1.5 tons, and a 700-kilometer sun-synchronous orbit payload capacity of 1.0 ton.
In the same family, there is the Kuaizhou-1 series solid launch vehicle, which is about 20 meters long, with a liftoff mass of around 30 tons, liftoff thrust of 60 tons, a thrust-to-weight ratio of 2.0, a low Earth orbit capacity of 0.3 tons, a 500-kilometer sun-synchronous orbit capacity of 0.25 tons, and a 700-kilometer sun-synchronous orbit capacity of 0.2 tons. Its main purpose is to provide launch services for small satellites weighing around 300 kilograms into low Earth orbit.
