We are building a 40-kilometer gun that launches cargo to orbit.
Everything planned for orbit, from depots to stations to in-space industry, needs far more mass launched than rockets will supply. A rocket burns an entire vehicle to deliver a small payload fraction.
Our launcher stays on the ground. It fires a projectile up its barrel and is ready to fire again the same day. The cost of a shot is gas, electricity, and a simple vehicle.
A 40 km evacuated barrel built from sectioned steel tube, driven by compressed hydrogen. The full length is used for acceleration, so the ride stays gentle, within reach of properly mounted conventional satellite hardware, not just hardened cargo. A small onboard stage circularizes the orbit after exit.
