Slingshot aims to provide a user-friendly astrodynamics experience to those looking to design spacecraft trajectories. Currently in the early phase with basic features.

• Full solar system of planets "on rails" - planets move in elliptical inclined orbits
• Multiple numerical integration models, including Runge-Kutta and Forest-Ruth symplectic models
• Pseudo-adaptive step control allows high fidelity when close to bodies and low fidelity in deep space
• Basic simulation controls, including integration length and time rate
• Maneuver nodes that allow instantaneous changes in velocity
• Switching between references frames for both maneuvers and trajectory plotting
• A slick UI

• More control over the propagation algorithms
• More minor solar system bodies, moons, rings, etc
• Maneuver node design tools
• Maneuver node visualization
• Rotating reference frames
• 2D plots to aid trajectory design
• Visual additions - Lagrange points, manifolds, gravitational potential plots, and more
• Attitude control simulation
