Is it just dumb luck that our probes (e.g. Juno, Voyager I, Voyager 2) never collide with even the smallest rocks in space? Is space in our solar system so void that the odds of a collision are so low? Does NASA (and other global space programs) have details about natural debris throughout our solar system that they can avoid collisions through navigation?
In: Physics
NASA knows where most of the asteroids are and thus knows where the asteroids aren’t. They know that there are so few asteroids that they only check to see if there is a chance of collision because it would be negligent otherwise. Despite checking, they’ve never had to adjust the course of a probe and most probes don’t even spot a single asteroid.
