Researcher proposes satellite to detect nuclear warheads in orbit
Areg Danagoulian, an MIT associate professor, published a proof-of-concept in Nature for an "inspector" satellite that could detect neutrons produced when high-energy protons in the inner Van Allen belt hit uranium in a thermonuclear weapon. The design filters incoming protons and uses directional detection to separate neutrons from the suspect satellite versus Earth albedo neutrons, and a modeled 2.5-mile (4 km) separation produced a detectable signal. The approach addresses a verification gap in the Outer Space Treaty as more nations expand orbital capabilities, and the author hopes others will develop prototypes.
A warhead could emit about 40 million neutrons per second.
Context
Many more satellites now orbit Earth and nations are launching more often. The Outer Space Treaty bans space nuclear weapons but has weak verification. If tested, this sensor could lead to prototype development and new verification steps.
