3D simulator that models planets, orbits, propulsion systems
Celestial Vehicle Propulsion Simulator launched on November 15, 2025 with 6 votes, #2,995 of 9,796 launches that month.
In plain words
Celestial Vehicle Propulsion Simulator is a 3D interactive tool that models space travel within our solar system using real astronomical data and physics calculations. Users can pilot spacecraft between planets using various propulsion methods, from conventional chemical rockets and ion drives to theoretical options like antimatter engines and warp drives. Travel times and distances reflect actual orbital mechanics, allowing exploration of the practical challenges and scales involved in interplanetary missions.

From the sources
This simulator uses real astronomical data and physics calculations to demonstrate the challenges, and scale, of space travel just within our own solar system. Distances and travel times are based on actual orbital mechanics and propulsion capabilities. You can choose from existing propulsion methods such as chemical rockets, ion drives, solar sails, but also hypothetical ones like anti-matter, light speed, and an Alcubierre Warp Drive.

This simulator uses real astronomical data and physics calculations to demonstrate the challenges of space travel. Distances and travel times are based on actual orbital mechanics and propulsion capabilities. Fly the Hail Mary! Powered by Astrophage — an alien micro-organism that converts mass directly into energy — the Spin Drive accelerates at a constant 1.5G. Flip and burn at the midpoint to decelerate for arrival.

Just for fun and self education, I've built this over a weekend to teach myself why orbits exist, not just show planets going around. Something that was never clearly explain to me in school. It opens with a guided tour that builds the idea up step by step: two bodies and the equal/opposite force, inertia (the Sun is removed and Earth just drifts straight), then "an orbit is falling and continuously missing," cosmic velocities with a little rocket, Voyager 1 & 2's real gravity assists (the clock runs the actual 1977–1989 dates so the planets orbit into their grand-tour alignment and the…

Rocket Launch and Orbit SimulatorJan 2026 · donutthejedi.com · ▲166I (17y/o) have been developing a rocket launch simulation that allows the user to explore what it's like launching a rocket from earth and putting it into orbit. This idea originally started as an educational simulation but as i've gone more down the rabbit hole the more i've wanted to make it realistic. The problem is that I've never had a formal orbital mechanics class or anything like that so I don't know what I'm missing, what I currently have implemented is: Variable gravity Variable Atmospheric drag (US Standard Atmosphere 1976) Multi-stage rockets Closed-loop guidance /…
