Researchers have proposed detection schemes that could deter the placement of nuclear warheads in orbit, potentially enforcing a ban on such weapons. One approach exploits Earth's radiation belts to identify hidden nuclear devices.
These proposals come amid rising concerns over space-based nuclear threats. In 2024, a U.S. government official warned that Russia might be developing a satellite capable of carrying nuclear weapons, following the launch of a suspicious Russian satellite into low-Earth orbit in 2022.
According to Phys.org, a space sensor could spot hidden nuclear weapons in orbit with 99% accuracy. The three approaches detailed by Science Magazine aim to make covert deployment nearly impossible.
The implications are significant for global security. If deployed, such sensors could deter nations from weaponizing space, reducing risks of orbital conflict. However, verification and international cooperation remain challenges.
Critics argue the technology's effectiveness in real-world conditions is untested. Implementation would also require broad political consensus among spacefaring nations, a hurdle given current geopolitical tensions.
