西昌卫星发射中心成功实施天问二号“零窗口”发射

Core Points - The successful launch of the Tianwen-2 probe marks China's first asteroid exploration and sample return mission, representing a significant step in deep space exploration [1] - The launch was executed with a "zero window" approach, meaning the actual launch time deviated from the optimal launch window by no more than one second, ensuring precise trajectory and fuel efficiency for subsequent missions [1] - The Xichang Satellite Launch Center has optimized the entire rocket launch process, implementing multiple safety measures and emergency plans to enhance reliability and safety during the launch [1] Group 1 - The Xichang Satellite Launch Center was established in 1970 and has successfully launched various missions, including Chang'e, Beidou, Fengyun, and Tianwen, contributing to China's advancements in space exploration [2] - The center has overcome several key technologies, including low-temperature propellant high-flow fueling, zero-second drop, and corrosion protection, enabling it to handle high-density launch tasks at both Xichang and Wenchang launch sites [2]
