Challenges to Security in Space

Challenges to Security in Space was first published in early 2019 to address the main threats to the array of U.S. space capabilities, as well as to investigate space and counter space strategies and systems pursued by China and Russia, and to a lesser extent by North Korea and Iran. This second edition expands on that work by providing an updated, unclassified overview of the threats to US space capabilities, particularly those posed by China and Russia, as those threats continue to grow.
