亚洲首个电磁弹射微重力实验装置启动新一轮科学实验 把太空中的重力环境“搬”到地球（探一线）

Core Viewpoint - The launch of Asia's first electromagnetic catapult microgravity experimental device by the Chinese Academy of Sciences marks a significant advancement in simulating microgravity environments for scientific research, providing new pathways to explore phenomena that differ from those observed under normal gravity conditions [1][2]. Group 1: Device Overview - The electromagnetic catapult microgravity experimental device simulates microgravity conditions on Earth, allowing for various scientific experiments across different disciplines [1]. - The device operates by rapidly launching an experimental capsule, creating a brief microgravity environment for approximately 4 seconds during ascent and descent [1][2]. - The structure includes a 44-meter tall tower with a 40-meter steel body, featuring triangular guide rails and linear motors that provide electromagnetic propulsion [1]. Group 2: Experimental Efficiency - Compared to traditional microgravity devices, the electromagnetic catapult offers significant advantages in precision, efficiency, payload strength requirements, and cost [2]. - Traditional drop tower devices can conduct only 2-3 experiments per day, while the new device can initiate a second experiment within 10 minutes [2]. - Since its trial operation began in July 2023, the device has completed over 300 microgravity experiments across six categories, including fluid physics and combustion science [2]. Group 3: Future Applications - The device is set to support over 1,000 planned experiments simulating microgravity, lunar gravity, and Martian gravity, contributing to major scientific projects and providing technical support for manned spaceflight and deep space exploration [2].
