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 provides a new platform for scientific experiments in microgravity environments, which can reveal phenomena that differ significantly from those under normal gravity conditions [1][3]. Group 1: Device Overview - The electromagnetic catapult microgravity experimental device simulates microgravity conditions on the ground, allowing for various scientific experiments [1]. - The device features a tower approximately 44 meters high, with a steel structure of about 40 meters, and utilizes linear motors to provide electromagnetic propulsion for the experimental cabin [1][2]. - The device can achieve effective microgravity time of up to 4 seconds during its operation, and it can also simulate low-gravity environments like those on the Moon and Mars [1][3]. Group 2: Experimental Efficiency - Compared to traditional microgravity devices, the electromagnetic catapult offers significant advantages in simulation precision, experimental efficiency, payload strength requirements, and cost [3]. - Traditional drop tower devices can only conduct two to three experiments per day, while the new device can initiate a second experiment within 10 minutes [3]. Group 3: Research and Future Plans - 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 [3]. - The company plans to conduct over 1,000 additional experiments related to microgravity, lunar gravity, and Martian gravity, providing essential support for major projects in manned spaceflight and deep space exploration [3].
