Current problem in interplanetary travel: Getting out of the planetary plane. Current attempted solution: Brute force. But no rocket so far is able to reach escape velocity and orbit the sun the other way to the plane. - Proposing a solution: Swinging. Letting rocket's own inertia keep the speed until it starts falling, then turning around and accelerating for a while, and repeat. Proposing a better solution: Swinging behind a planet, to draw acceleration from its gravity, practically accelerating without fuel. Gravitational assist in this way is more complicated than along interplanetary plane where it is simply freefall to the destination. - Space is the next frontier of our flesh civilization, but the #FractalUniverseRevolution is the final frontier for all physics-based lifeforms!
