At 12:00 PM on April 1, 2025, the Long March 2D launch vehicle was successfully launched with the internet technology test satellite from Jiuquan Satellite Launch Center, precisely delivering it into the destination orbit, signaling a complete success of the launch mission. The Long March 2D launch vehicle used for this mission is a level 2 carrier rocket with liquid propellant of normal temperature developed by Shanghai Academy of Spaceflight Technology.
The test team of Long March 2D launch vehicle always stays true to its aspiration and never forgets its mission. Under the strong leadership of the two chief engineers of the model team, all team members strictly adhered to the production and quality assurance plans at the launch site, and completed all tasks with the required quality on schedule and according to requirements, which ensured the success of the flight test. A satellite fairing made of composite materials with a diameter of 3.8 meters was successfully used in this mission. With a lightweight design and advanced material technology, this fairing achieved three significant improvements over metal fairings of the same size: It effectively expands the payload envelope of the satellite, significantly increasing the mission adaptability; the electromagnetic wave transmission performance is significantly improved, ensuring the reliability of the wireless communication link; The inner surface is smooth and even, making it easy to clean, which meets the requirements of space environments for high cleanliness. The weather in Jiuquan was extremely dry in March, with frequent sandstorms. To ensure the mission proceeded smoothly, the model team established various control measures for electrostatic protection and debris management during their pre-shift meeting.
This launch mission is the 97th launch of the Long March 2D launch vehicle, the 231st launch of the Long March series of launch vehicles developed by Shanghai Academy of Spaceflight Technology, and the 567th launch of the Long March series of launch vehicles.
