Rocket Simulator Online is a free browser-based rocket launch simulator — no download required. Launch rockets to orbit using realistic physics, gravity turns, and orbital mechanics. Choose from manual flight, guided trajectory, or orbital spawn modes.
This free rocket launch simulator models real aerodynamic drag, dynamic pressure (Max Q), multi-stage separation, and Tsiolkovsky rocket equation performance. Watch live telemetry — altitude, velocity, Mach number, apoapsis, and periapsis — as you fly to orbit. It doubles as a rocket launcher simulator and orbital mechanics sandbox.
Use the built-in rocket builder to design custom multi-stage rockets online. Tune engine thrust, specific impulse, propellant mass, payload, and fairing — then fly your design. The rocket building simulator lets you explore how staging, thrust-to-weight ratio, and delta-v affect your ability to reach orbit.
This free online rocket simulation runs entirely in your browser with no download, no install, and no account needed. Works on desktop and mobile. Learn orbital mechanics, practice gravity turns, and experiment with rocket design — all for free.
