Summary

Story summary

Tohoku University scientists developed bidirectional plasma thruster technology using fusion reactor tech to address debris in low-Earth orbit.
The device uses opposing plasma beams to decelerate larger debris.
Tests show up to 25 millinewtons, near what's needed to deorbit a one-ton object in 100 days.
Urgent action is needed to prevent Kessler Syndrome, with logistics, costs, and international cooperation as challenges.
