At 12:11 on September 20, 2024, the Long March 2D lifted off from Taiyuan Satellite Launch Center, successfully delivering the Jilin-1 Wideband 02B (01-06) satellites into their designated orbits. The launch mission was a complete success.

The Long March 2D rocket, developed by the Shanghai Academy of Spaceflight Technology (SAST) as the leading role, is a two-stage normal-temperature liquid-propellant launch vehicle known for its characteristics of high reliability, cost-effectiveness, and strong adaptability. It supports a variety of launch configurations, including single-satellite, multi-satellite parallel, serial, and rideshare missions. The launch vehicle has a payload capacity of 1.3 tons for deploying satellites into a 700-kilometer sun-synchronous orbit.

In September, Taiyuan Satellite Launch Center experiences frequent rain, presenting challenges due to high humidity and prolonged rainfall. To address this, the launch team meticulously implemented and checked enhanced rain protection measures, building upon previous practices to eliminate any potential risks to the launch. Given the complexity of integrating multiple satellites with the launch vehicle, the team conducted thorough pre-launch planning and rehearsals before arriving at the launch center. Upon arrival, they executed each step with precision, carefully documenting the entire process to prevent any possible errors and ensure mission success.

For this launch, the launch vehicle employed a non-electric initiating satellite separation mechanism, which better ensured the design of the satellite separation sequence. Additionally, high-precision, miniaturized ten sensor axes and on-board computers were tested during the flight, allowing for real-world flight test evaluation of these key products without affecting the primary mission. This marks another step forward for future applications of these technologies.

This launch mission is the 91st launch of Long March 2D, the 218th launch of the Long March series of launch vehicles developed by SAST as the leading role, and the 536th launch of the Long March launch vehicle family.
