Space Harbors

Every star, planet and spacecraft is from real astronomy data. Fly the open universe of 343 star systems (unlock 4,723 more) and learn about the cosmos as you go.

Space Harbors is a space game built on real astronomy. Every star, planet, moon and spacecraft in it exists, placed from real data, and each one has a card that tells you what we actually know about it, with the sources.

FLY THE OPEN UNIVERSE Free roam 343 star systems from the start, and unlock 4,723 more from NASA's catalog of planet-hosting stars. Cruise past Saturn's rings, warp to Betelgeuse and look for its newly reported companion star, or fly out to the black hole at the center of the galaxy. No set path, and no fuel, hazards or damage unless you switch them on.

GUIDED TOURS Buckle up for seventeen guided tours while Lumen, your ship's assistant, tells you what you are looking at: Saturn's rings and nine of its moons, the seven planets of TRAPPIST-1, dead stars and black holes, the spacecraft at work right now. Three tours are free; the rest open as you explore, or all at once with the Tours Pack.

THREE STORIES, SET AMONG THE STARS Before the Sun: retrace how people worked out where everything came from, at the objects where they found it. The Star Cartographers: trace the constellations as cultures around the world drew them, then fly into the figures and watch them come apart. The Last Harbor: a fictional story set among the real stars. The ark has left Earth, and you scout real systems for a new harbor while the Hollow close in. Chapter 1 of every story is free.

FOLLOW REAL SPACECRAFT Log a spacecraft, then open its console from your ship: its status, its mission timeline from launch day to today, and the keepsakes aboard. Voyager 1's log runs from 1977 to the memory chip engineers patched from 24 billion kilometers away.

MAKE THE CALLS MISSION CONTROL MADE Land a rover on Mars or put a satellite into orbit, one decision at a time. Choose wrong and you will see what really happened on the missions that came before, with the sources to read more.

DRIVE, DIVE, LAUNCH AND LAND Ride a rocket through Max-Q while the command center watches live. Drive a rover over the hills of Mars. Dive through Saturn's rings for ice. Fly Enceladus' geysers, touch down on other worlds, drill cores and match starlight to the elements inside it. Then train at the Training Center on Earth.

BATTLE Tag, battle, race or capture the flag against computer pilots in the Solar System.
