Core Viewpoint - The Asian first electromagnetic catapult microgravity experimental device has commenced a new round of scientific experiments, focusing on life sciences [1][3]. Group 1: Experimental Device Overview - The electromagnetic catapult microgravity experimental device is approximately 44 meters tall, equivalent to a 15-story building, providing effective microgravity time of up to 4 seconds [3]. - The entire structure weighs over 300 tons and is secured by more than 40,000 bolts, ensuring precision and ease of future adjustments [5]. - The experimental chamber has a diameter of 1.2 meters and a height of 2 meters, resembling a large elevator [5]. Group 2: Scientific Experiments - The current experiment involves six drug-injected mice, aiming to study the effects of microgravity on targeted drug delivery across the blood-brain barrier, marking the first such experiment conducted on the ground in China [8]. - The electromagnetic catapult operates on the same principle as those used on aircraft carriers, but in a vertical direction, accelerating the experimental chamber to a speed of 20 meters per second [10]. Group 3: Advantages of the Electromagnetic Device - Compared to traditional drop tower experiments, the electromagnetic device significantly reduces impact forces from over 20g to about 5g, enhancing safety and efficiency [11]. - The electromagnetic system allows for more frequent experiments, with traditional setups limited to three experiments per day, while the new system primarily incurs electrical energy costs, reducing overall experimental expenses [11]. Group 4: Future Developments - Plans are underway to simulate lunar microgravity conditions on the ground later this year, along with the construction of a new facility capable of achieving 20 seconds of microgravity at a depth of 800 meters [12].
