太空安全挑战报告（英）-美国国防情报局-2022-80页

SCOPE NOTE Challenges to Security in Space was first published in early 2019 to address the main threats to the array of U.S. space capabilities, and examine space and counterspace strategies and systems pursued primarily by China and Russia and, to a lesser extent, by North Korea and Iran. This second edition builds on that work and provides an updated, unclassified overview of the threats to U.S. space capabilities, particularly from China and Russia, as those threats continue to expand.
