New detection system promises early warnings to help spacecraft dodge orbital debris
SMRTR summary
Tiny shards of space debris traveling at extreme speeds now have a watchful eye tracking their potentially destructive paths. Southwest Research Institute has developed a new detection system that spots debris strikes on satellites, even when no visible damage appears.
The micrometeoroid and orbital debris detection system combines structural panels with sensors that record impacts and analyze data to determine a particle's size, speed, and composition.
"Most spacecraft survive minor impacts without systems breaking or operators on Earth knowing," explains Dr. Sidney Chocron, who led the system's development. "Our device is designed to send data back to Earth with important insights before any damage is apparent."
Researchers tested the system using a light gas gun that fires small projectiles at high velocities in vacuum conditions, simulating orbital collisions.
With thousands of debris fragments orbiting Earth and more satellites launching yearly, the technology could become part of an early-warning network. When one satellite detects a strike, it could alert others nearby, potentially allowing them to maneuver away from danger.
SwRI now seeks funding for a space-ready version to map Earth's orbital minefield and better protect future missions.
