US scientists to detect tiny 1 cm-long ‘grenades’ with Space Debris Hunter satellite

SMRTR summary

Scientists are developing a satellite called Space Debris Hunter to detect tiny space junk as small as 1 cm in Earth's orbit. The satellite will use plasma-based sensors to calculate debris distance, approach angle, and trajectory, potentially helping prevent collisions with critical satellites that perform thousands of avoidance maneuvers annually.
