Asteroid Mining: Microgravity Anchoring & Reaction Forces

Interactive 3D simulation of the Newton's-third-law problem in asteroid mining: drilling reaction force can throw an unanchored spacecraft off a low-gravity asteroid. Tune the asteroid's size and density, engage a harpoon anchor, and watch the spacecraft and ejected regolith respond.

Excavating an asteroid means pushing a drill or scoop into regolith — and by Newton's third law, the regolith pushes back on the spacecraft. This simulation models that reaction force against a real gravity model of a rotating asteroid: set the body's radius and bulk density to see how surface gravity and escape velocity change, dial in a drilling reaction force, and toggle a harpoon anchor to see the difference between a spacecraft that holds position under tension and one that drifts — or entirely escapes — an asteroid too small to hold it down.
