What is Space Travel?

Space Travel is an early Unix computer game that lets players pilot a spaceship through a top‑down, monochrome representation of the solar system. Planets and moons are drawn to scale in size and distance, with simplified circular orbits and realistic gravitational pulls. The game offers no set objectives beyond attempting landings on various celestial bodies, and its open source nature allows players to modify gravity, scaling, and display options for a customized experience.

Key Features of Space Travel

The solar system is rendered with planets and moons to scale in both size and distance.
Gravitational pull is calculated for each body, with the strongest pull affecting the ship at any moment.
Players can zoom the view to travel across the system in seconds or slow down for precise landings.
The ship remains centered while the universe rotates, giving a unique navigation perspective.
Landing requires crossing the surface line at a low enough speed, adding a skill challenge.
Source code is publicly available, allowing users to tweak gravity levels and display conventions.
The game runs in a text‑mode terminal with white line graphics on a black background.
No defined win condition encourages free exploration and experimentation.
