What is I, Voyager?
I, Voyager is
- an open-source software planetarium
- a development platform for creating games and educational apps in a realistic solar system.
It is designed to be improved, modified and extended by the community. I, Voyager runs on the open-source Godot Engine and primarily uses Godot’s easy-to-learn GDScript (similar to Python). It can be extended into an independent free-standing project (a game or other software product) using GDScript, C# or C++.

Where did I, Voyager come from?
Creator and lead programmer Charlie Whitfield stumbled into the Godot Engine in November, 2017. By December there were TestCubes orbiting bigger TestCubes orbiting one really big TestCube*. The name “I, Voyager” is a play on Voyager 1, the spacecraft that captured an image of Earth from 6.4 billion kilometers away. I, Voyager became an open-source project on Carl Sagan’s birthday, November 9, 2019.
(* Godot devs, bring back the TestCube!)
