Starship Space Program is a Starship and Super Heavy flight sim for Windows PC: hops, hot staging, the booster catch on the tower, and on to orbit.

A few things other UE devs might find interesting:

- The vehicle physics are my own 6-DOF model, stepped at 500 Hz in double precision, with the Unreal actors following it.
- The planet is scaled space with a 16k Earth and night lights; orbits are n-body from JPL ephemerides.
- Starbase is built from lidar, aerial imagery and Sentinel-2 ground albedo.
- All lighting is dynamic (Lumen on High/Epic) with a physical Sun and exposure.
- The UI is pure Slate, no widget blueprints.
