With SpaceSim, users can travel through a real-time, UTC-driven 3D Solar System and inspect source-linked scientific state data. The simulator also features the ability to observe Earth from a pinned NASA ISS trajectory, build procedural stars, visit compact objects, and collect virtual postcards of your discoveries.

To ensure transparency and educational accuracy, SpaceSim clearly labels all of its content as scientific, reconstructed, representative, procedural, experimental, or promotional.
