China’s Long March 3B Rocket Launches First Space Mission of 2025
China marked a significant milestone early Tuesday with the successful launch of its first space mission of 2025. A Long March 3B carrier rocket carried the experimental Shijian 25 satellite into space, showcasing the nation’s growing expertise in space technology.
Long March 3B: A Powerful Start to 2025
The rocket lifted off at 4 am from the Xichang Satellite Launch Center in Sichuan province. It quickly delivered the Shijian 25 satellite into its designated orbit, according to China Aerospace Science and Technology Corp (CASC), the country’s primary space contractor.
The satellite, developed by CASC’s Shanghai Academy of Spaceflight Technology, will test critical technologies. These include orbital refuelling and life-extension systems, which are pivotal for future space missions.
Key Features of the Long March 3B
The rocket, developed by the China Academy of Launch Vehicle Technology in Beijing, is a reliable mid-lift vehicle. It stands 56.3 metres tall with a diameter of 3.35 metres and is equipped with engines propelled by a liquid fuel. The three-stage rocket is supported by four side boosters, each 2.25 metres wide, and weighs 456 metric tonnes when fully fuelled.
Notably, the Long March 3B achieved a historic milestone in December 2024, completing its 100th flight. This makes it the first Chinese rocket model to reach such an accomplishment. To date, all 102 launches of this rocket have taken place at the Xichang spaceport.
An Active Year Ahead for China’s Space Program
The Long March 3 family, which includes the 3A, 3B, and 3C models, is slated to conduct over 10 missions in 2025. Last year, China carried out 68 space launches, setting a new national record. Of these, 66 were successful, reflecting the country’s consistent progress in space exploration.
