Stellar Horizons

Stellar Horizons is a “build your own space program” game in which you lead one of the seven Earth factions to explore and develop our solar system. Designed by a real space engineer with a PhD in long-duration spaceflight from MIT, Stellar Horizons is intended to be a realistic representation of humanity's first steps to the stars between 2030 and 2169, with each round representing one year of time. You manage your faction's space program, outposts and fleets that span the solar system, although you also have some influence on your faction's politics on Earth, as space development gains greater importance.

Movement is based on real physics. Move from orbit to orbit or perform long-range transfers to travel between planetary systems such as Earth, Mars or Jupiter. As you send robotic explorers and crewed vehicles to explore the solar system, they bring back valuable data to advance your scientific research. Technologies are intended to represent plausible extensions of current development over the next 150 years: there are no teleporters or warp drives, but you will be able to develop rockets powered by fusion and even antimatter. In the fields of engineering and biology, you will eventually be able to build space elevators and put your crews into safe hibernation for long journeys.

You will have access to a wide variety of robotic explorers and crewed ships. These range from tiny probes intended simply to take pictures as you fly past Jupiter, to giant destroyers, cruisers and battleships that ply the space lanes with peaceful or hostile intent. New ship types become available as you gain access to better technology during the game.
