Summary

Story summary

Tohoku University researchers created a plasma propulsion system to safely remove space debris.
Earth's orbit is filled with inactive satellites and debris, threatening active missions.
Traditional methods require direct contact, risking further debris movement.
The new system uses a plasma ejection thruster to decelerate debris without contact.
Laboratory tests indicate it can triple deceleration force, clearing debris in roughly 100 days.
The thruster, powered by argon, is cost-effective and scalable for future missions.
Successful real-world testing may transform debris management in crowded orbits.
