长征12B首飞圆满成功，卫星精准入轨
China’s new Long March 12B carrier rocket completed its maiden flight on Thursday, marking a fresh advance for the country’s space program. The launch took place at the Wenchang Space Launch Site in Hainan Province. The rocket successfully placed an experimental satellite into a predetermined orbit, according to Chinese space authorities. The event highlights China’s growing ambitions in space technology and its push to develop a diverse fleet of launch vehicles.
The Long March 12B is a two-stage liquid-fueled rocket designed for medium-lift missions. It stands roughly 52 meters tall and has a liftoff weight of about 220 metric tons. Its first stage is powered by four YF-100K engines burning liquid oxygen and kerosene. The rocket is capable of delivering up to 4.5 tons of payload to a 700-kilometer sun-synchronous orbit, filling a gap in China’s launch vehicle family.
