MIT researcher Areg Danagoulian has proposed a satellite-based sensor system designed to detect nuclear weapons in orbit. The system uses neutron detectors to identify radioactive material by measuring spallation reactions. Calculations indicate the sensors could verify the presence of nuclear components with high accuracy during close proximity flybys of suspect satellites.

The 1967 Outer Space Treaty prohibits nuclear weapons in space, but current verification methods remain limited. This proposal offers a technical framework for monitoring compliance, addressing concerns regarding anti-satellite capabilities. By providing a method to distinguish between natural radiation and nuclear material, the technology could assist policymakers and national laboratories in developing systems to enforce international nonproliferation agreements.

MIT Professor Areg Danagoulian is proposing a way to determine if a satellite orbiting Earth contains a nuclear weapon. He describes his idea for a satellite-based sensor system that could orbit close by a suspect satellite and detect neutrons generated by high-energy protons colliding with radioactive material.
