CCTV News reported that at 9:08 Beijing Time on December 13, 2025, the Kuaizhou-11 Yaoyu No.8 launch vehicle was launched from the Jiuquan Satellite Launch Center, successfully sending the Di'er No.5 space experimental vehicle and the Huixi No.5 Phase II satellite into orbit, with the flight test mission achieving success.

The Kuaizhou-11 rocket was developed and supervised by China Aerospace Science and Technology Corporation Rocket Technology Co., Ltd. It has a carrying capacity of 1 ton to a 700 km sun-synchronous orbit, with a fairing diameter of 2.65 meters. It features high flight reliability, high orbital accuracy, short preparation cycle, low support requirements, and low launch cost, making it adaptable to a variety of commercial launch missions.

This mission marked the fourth flight of the Kuaizhou-11 rocket and the 37th flight of the Kuaizhou series launch vehicles.

According to Hubei Daily, the Di'er No.5 space experimental vehicle is the first commercial unmanned spacecraft in China, developed by Zhiwei Yutong Technology (Wuhan) Co., Ltd. The spacecraft is equipped with 34 experimental devices totaling more than 70 sets, which will carry out in-orbit verification in multiple fields such as microgravity science and space pharmaceuticals, marking that China's commercial aerospace has entered a new stage of large-scale application.

Model of Di'er No.5 Hubei Daily

According to the introduction, Di'er No.5 belongs to the Zhiwei Technology B300 orbiting version series, and is a multi-functional space platform specifically designed for commercial scenarios. It weighs approximately 600 kg, with an internal usable space of no less than 1.8 cubic meters, and can carry a payload weight of 300 kg. It can provide long-term power supply of 200 W and peak power of 1000 W for the payload, and can manage 100 active payloads. "Di'er No.5" will actively deorbit after being in orbit for one year, ensuring both mission needs and space safety throughout the process.

Previously, Zhiwei Technology had successfully launched the "Di'er No.1" and "Di'er No.3" spacecraft in 2023 and 2024, respectively.
