v0.2Source Code

Based on brachistochrone trajectory calculations from Project Rho. All flights assume continuous acceleration to midpoint, then continuous deceleration. This is an idealized model, and does not account trajectory corrections, orbital insertions, or other maneuvers that would probably be neccesary in the real world.
