Space Pioneer announcement(machine translate):
During the test run, the first-stage rocket ignited normally, and the engine thrust reached 820 tons. Due to structural failure at the connection between the rocket body and the test bench, the first-stage rocket detached from the launch pad. After liftoff, the computer on the rocket automatically shut down, and the rocket fell to the ground. In a deep mountain 1.5 kilometers southwest of the test platform, the rocket body fell into the mountain and disintegrated. The test site was far away from the urban area of Gongyi. Before the test, we worked with the local government to improve safety measures and organized the evacuation of surrounding people in advance. After investigation, there were no casualties.
Tianlong 3 is a large liquid launch vehicle customized by Space Pioneer for the construction of my country's satellite Internet constellation. Its product performance is comparable to SpaceX's Falcon 9. Its diameter is 3.8 meters, its take-off mass is 590 tons, and its low-Earth orbit (LEO) transport capacity is 17 tons, with a sun-synchronous orbit (SSO) capacity of 14 tons.
