MIT professor develops method to verify compliance with Outer Space Treaty
Danagoulian
Areg Danagoulian of the Department of Nuclear Science and Engineering at the Massachusetts Institute of Technology is proposing a mechanism for verifying that Earth-orbiting satellites are in compliance with the Outer Space Treaty, which prohibits the placement of nuclear weapons in space. Danagoulian’s “concept and feasibility study,” titled “Verification of the Outer Space Treaty with cosmic protons,” was published recently in the journal Nature.
