OpenRocket Simulator: Free Rocket Design and Flight Simulation Tool

OpenRocket Simulator is an open-source tool for designing rockets and running flight simulations on Windows, macOS, and Linux.

The software includes a large database of real-world parts and lets users specify material densities and surface treatments.

It can run 6DoF simulations using over 50 variables and render designed rockets in 3D.

The OpenRocket source code is available on GitHub, and the tool may help hobbyists inspired by recent lunar missions.
