Summary

Story summary

MIT physicist Areg Danagoulian proposed an inspector satellite that flies within kilometres of a suspect spacecraft to detect illicit nuclear weapons.
Simulations indicate the sensor can confirm a warhead with 99 percent accuracy in one hour at 1,000 m, or in a week at 4,000 m.
The plan cites Russia’s Cosmos 2553, launched February 2022, as a suspected nuclear platform, warning that close maneuvering raises collision risks and needs a treaty-based verification scheme.
