培育“航天月季” 力鸿一号完成亚轨道飞行试验任务

Core Viewpoint - The successful return of the Lihong-1 suborbital flight experiment, which carried rose seeds, aims to explore the effects of space radiation on plant genetics and establish a unique brand of "space roses" for industry upgrades [1][3]. Group 1: Mission Overview - The Lihong-1 vehicle completed its suborbital flight test on January 12, reaching an altitude of approximately 120 kilometers and providing over 300 seconds of stable experimental conditions for scientific research [1]. - The mission's primary payload was a self-developed microgravity laser additive manufacturing device from the Chinese Academy of Mechanics, which preliminarily verified the feasibility of space manufacturing supported by rocket platforms [3]. Group 2: Technical Achievements - The design team optimized the aerodynamic shape of the payload capsule to enhance deceleration and stability during re-entry, ensuring safe parachute deployment [3]. - The flight vehicle achieved a landing accuracy of within a hundred meters, thanks to extensive analysis of the parachute dynamics and its impact on the capsule's flight trajectory [3]. Group 3: Future Developments - The Lihong series of vehicles will expand in scale for multiple reuses, with ongoing reliability tests to enhance capabilities for manned life support and high-reliability escape technologies [3]. - The goal is to achieve long-term orbital presence and reliable re-entry by 2028, transforming the Lihong series into a routine space manufacturing and scientific research platform [3].
