This is a game about exploring space with realistic orbital physics. Arrows keys or ASDW control the ship. Speed buttons are at the top. Drag right mouse or scroll to zoom. You can land if you don't go too fast. Build stations to make navigating locations easier. Build a lab and buy ship upgrades with the science you get from exploring the solar system. Science all the things. This game auto-saves, so you can come back and science more later.
