Autonomous Hazard Avoidance Systems for Planetary Landers

Quick fact

A planetary lander's autonomous hazard avoidance system can scan the surface, identify hazards like boulders and steep slopes, and select a safe landing site within about one second—without any human input.

Why this is interesting

Imagine trying to land a spacecraft on a rocky, cratered world millions of kilometers away—where a single wrong choice could end the mission. How does the vehicle pick a safe spot when it only has seconds to decide?
