During on 17 June 2026 at 1158 Hong Kong SAR- Beijing Time launching from one of many complexes酒泉衛星發射中心 Jiuquan Satellite Launch Center in Dongfeng Aerospace City – inner Mongolia –China – People’s Republic of China on中國製造 Expace Technology Corporation, , the Kuaizhou-11 Y13 solid carrier rocket ignited and lifted off at the Jiuquan Satellite Launch Center deploying the sending the successfully sending, the Kuaizhou-11 Y13 carrier rocket successfully sent the Microspace 05 group of satellites into their predetermined orbit from the Jiuquan Satellite Launch Center. This was the sixth flight of this type of rocket and the first time that the Kuaizhou series rockets officially undertook the mission of batch networking of the “Microspace” low-Earth orbit constellation.
I. Core Facts
- Launch time: 11:58 AM Beijing time on June 17, 2026.
- Launch site: Jiuquan Satellite Launch Center.
- Rocket model: Kuaizhou-11 Y13 carrier rocket.
- Payload status: The Microspace 05 group of satellites was successfully sent into its predetermined orbit.
- Mission nature: This flight test mission was a complete success.
II. Mission Background and Characteristics
1. Satellite Payload Details
- The Microspace 05 satellite constellation was built by Beijing Future Navigation Technology Co., Ltd., and belongs to the third batch of networking satellites of the “Microspace” low-Earth orbit constellation system.
- This marks the first launch of the Kuaizhou series rockets to officially undertake the mission of batch networking of this constellation.
- After the satellite enters orbit, Beijing Future Navigation Technology Co., Ltd. will conduct a series of on-orbit tests, and provide system services and promote the application of satellite technology once the satellite is in its designated orbit.
2. Rocket Technical Parameters
- It has a takeoff mass of 78 tons, a body diameter of 2.2 meters, and a total length of 25 meters.
- The payload capacity to a 700 km sun-synchronous orbit is no less than 1 ton, and the maximum payload capacity to a low Earth orbit is 1.5 tons
- The main structure of the entire rocket is made of carbon fibre composite material.
- It adopts a configuration of a three-stage solid rocket motor and an upper-stage liquid rocket motor in series.
- It adopts a vehicle-mounted mobile launch method and a “three-horizontal” mode (horizontal assembly, horizontal testing, and horizontal transportation).
3. Task sequence number statistics
- This was the sixth flight of the Kuaizhou-11 carrier rocket.37
- This was also the 39th flight of the Kuaizhou series carrier rockets.3
- This will be China’s 43rd space launch in 2026.19
- The 289th launch from the Jiuquan Satellite Launch Center.
