About This Launch
Space Simulator Online is a free 3D space explorer that runs in any modern browser. Fly from Earth through the Solar System and out to the Milky Way with no install and no account. Visit planets and moons, follow guided tours along spacecraft trajectories, and explore exoplanet and gravitational-wave data. The interface is available in 10 languages. It uses public NASA and JPL data and is not affiliated with NASA.
Why I Built This
I wanted a no-install way for students and curious people to fly the real Solar System using public NASA/JPL data, so I built Space Simulator Online as a free browser app.
