中国航天电子技术研究院负责人表示，此次合作，既是战略所需，也是发展所向，体现了地方政府 与央企在技术、资源和应用场景上的互补协同，有助于推动低空产业从试点走向规模化应用。 本次签约是双方落实国家发展低空经济相关政策的具体举措，标志着海南省与中国航天电子技术研 究院在低空领域合作的实质性推进。根据协议，双方将结合海南自贸港政策、海南省属国资国企资源优 势与中国航天电子技术研究院科技实力，共同推动海南省低空经济高质量发展。 未来中国航天电子技术研究院将从共建"一张网"、共筑"一平台"、共促"一链条"、共创"一机制"等 方面与海南深化合作，充分发挥航天系统工程、体系化和产业化能力优势，全力以赴支持海南低空经济 高质量发展，助力海南打造具有全球影响力的低空产业集群与创新高地。 省国资委与中国航天电子技术研究院签约合作 共促海南低空经济发展 省国资委负责人表示，海南省低空经济发展三年行动计划描绘了清晰的蓝图，希望省属国企主动作 为，当好低空经济合作落地的"主力军"，充分利用资源，主动做好对接服务，切实形成"全省一盘棋、 上下一股劲"的发展合力。 海南日报讯(海南日报全媒体记者 邵长春)10月15日，海南省国资委与中国航 ...

Core Viewpoint - The increasing risk of collisions due to space debris threatens satellite operations and space missions, prompting the development of a new non-contact, efficient debris removal technology by a Japanese research team [1][2]. Group 1: Space Debris Issue - The problem of space debris is becoming severe, with numerous defunct satellites, rocket remnants, and tiny fragments traveling at speeds exceeding that of bullets, posing significant threats to active satellites and spacecraft [1]. - The uncontrolled debris significantly increases the risk of sustainable human activities in space, highlighting the need for effective removal methods [1]. Group 2: Innovative Technology Development - The research team from Tohoku University has proposed and validated an innovative solution that utilizes plasma ejected from satellites to slow down space debris, encouraging it to deorbit and burn up upon re-entry into the atmosphere [1]. - Traditional methods of debris removal often rely on direct contact, which carries the risk of entanglement; however, the new method using plasma propulsion is gaining attention as a promising alternative [1]. Group 3: Technical Advancements - To enhance deceleration efficiency, the team introduced a special magnetic field structure called "tip" to confine the plasma plume and prevent its dispersion, achieving a deceleration force three times greater than previously reported in simulations [2]. - The propulsion system employs inexpensive and abundant argon gas as the propellant, demonstrating good economic viability and practicality for debris removal [2]. - The development of a "bipolar plasma jet type non-electrode plasma thruster" allows for simultaneous plasma ejection in both the direction of the debris and the opposite direction, counteracting recoil and maintaining the stability of the removal satellite [1][2].
