Asteroid Mining 2D: Radial Reaction & Orbital Ejecta

Interactive 2D cross-section simulation of the Newton's-third-law problem in asteroid mining: drilling reaction force can throw an unanchored spacecraft off a low-gravity asteroid, while ejected regolith traces real planar orbits — bound ellipses that fall back, or hyperbolic escapes — around the central-force gravity well.

2D cross-section counterpart to the reaction-force problem in asteroid mining. The spacecraft's motion along the anchor line is integrated as a true 1D radial equation — drill reaction force against gravity and tether tension — while every grain of ejected regolith is integrated as a genuine planar two-body orbit under the asteroid's central gravity, so grains below escape velocity trace bound ellipses back to the surface and grains above it sail away on hyperbolic paths and never return. Tune the asteroid's radius and bulk density, toggle the harpoon anchor, and watch how a modest drilling force can already exceed the surface weight of a body this small.

Interactive 2D cross-section simulation of the Newton's-third-law problem in asteroid mining: a drill's reaction force can throw an unanchored spacecraft off a low-gravity asteroid, integrated as a real radial equation of motion, while ejected regolith is integrated as a genuine planar two-body orbit — grains below escape velocity trace bound ellipses back to the surface, grains above it escape for good.
