Delta-V Academy is a hands-on 3D simulator for learning how orbits actually work. Spin the Earth, drag a satellite into orbit, change its altitude or shape, and watch orbital mechanics respond in real time. No math background required to start, and enough depth to challenge people who already know the difference between a Hohmann transfer and a ground track. WHAT YOU CAN DO - Fly ten guided lessons that build from the basics to full space situational awareness, each written for four levels: Kids, Novice, Intermediate, and Advanced. - Adjust altitude, eccentricity, and inclination with live sliders and see period, speed, and ground tracks update instantly. - Watch real mission replays, including Apollo 11's translunar injection, an ISS rendezvous, and JWST's cruise to L2. - Build satellite constellations and Walker deltas, then study their coverage. - Explore sensor geometry and space domain awareness with ground radar and space-based trackers. - Trigger a Kessler debris cascade and see why orbital congestion matters. - Capture screenshots and video of your own missions. LEARN AT YOUR LEVEL Pick Kids mode for plain-English labels and a friendly guided path, or step up to Advanced for J2 perturbations, oblate-Earth ground tracks, and multi-sensor architectures. Switch anytime. MISSION ARCHITECT Describe a mission in plain English and Delta-V Academy builds it for you in the simulator. A few tries a day are included free. FREE TO LEARN Every lesson and every difficulty level is free with a Delta-V Academy account. An optional Pro subscription unlocks unlimited Mission Architect use. Whether you are a student, a teacher, a space enthusiast, or a professional who wants an intuitive feel for orbital mechanics, Delta-V Academy turns abstract equations into something you can see and steer.
