Extreme solar activity or even a software glitch could put us just days away from a satellite collision in low-Earth orbit.
Lawrence Livermore National Laboratory creates a cislunar orbit map to help predict satellite stability and improve collision avoidance in increasingly crowded Earth orbits.
A new megahertz laser improves satellite and debris tracking, strengthening orbit predictions and space safety.
