Space Travel

In Space Travel the player is free to explore the solar system. The game uses a two dimensional scale model of the solar system and the player is free to fly around. Physics are simplified as the player is only affected by the single strongest pull at a given time. There are no explicit objectives in the game, but the player can navigate around the solar system and attempt landings on planets and moons. The space craft can be moved and turned and the simulation speed can be increased to quickly reach destinations.

In order to port the game to the PDP-7 the developer created his own operation system which would later evolve to become Unix.
