Commentary On Oct. 24, China launched its Shijian-21 into orbit. The satellite, according to China Aerospace Science and Technology Corp., is “tasked with demonstrating technologies to alleviate and neutralize space debris.” As Beijing sees it, American satellites constitute “debris.” Shijian-21 has a robotic arm that can be used to move space junk—there are more than 100 million pieces of it floating around the earth—or capture, disable, destroy, or otherwise render unusable other nations’ satellites. That arm makes Shijian-21 a “satellite crusher.” Brandon Weichert, author of “Winning Space: How America Remains a Superpower,” tells Gatestone that the Chinese satellite was launched into geosynchronous orbit, where many of America’s most sensitive satellite systems—those critical to Nuclear Command, Communications, and Control (NC3), surveillance, and military communications—are located. “Because the U.S. satellites in geosynchronous orbit are so far away from earth, they are both expensive and hard-to-replace,” he notes. “Losing any of these systems, with no replacements …
