Free Earth and Space Science Games
Look up and look down. This set of free earth and space science games covers the planet and beyond: catch transit dips and radial wobbles to find exoplanets in Signal Hunter, steer rotating storms with the Coriolis effect in Coriolis Cyclone and keep the planet's heat budget stable in Infrared Traffic.
Steward a generation ship across the stars in Seedship Saga and grow mineral crystals through nucleation in Crystal Nucleation. Each game is free, instant and classroom friendly, with real astronomy and Earth science inside.
Coriolis Cyclone
A fluid dynamics and atmospheric meteorology simulation game. Harness Coriolis deflection and pressure gradients to steer rain toward crops and deflect cyclones to open sea.
Crystal Nucleation
Launch dissolved mineral seed ions, trigger spontaneous crystal nucleation clusters and cleave unsupported mineral lattices in this deep sea arcade game.
Signal Hunter
Pilot a space telescope across a survey field, confirm transiting exoplanets and habitable zone worlds, catch auroral radio bursts and oxygen biosignatures while dodging stellar flares and eclipsing binary false positives in this astronomy arcade game.
Infrared Traffic
Direct Earth's photon traffic: harvest sunlight, place CO2, water vapor, methane and CFC molecules to absorb the right infrared bands and hold the planet in the Goldilocks zone in this greenhouse effect game.
Seedship Saga
Steward a generation ship of named colonists across an endless voyage: assign jobs, raise new generations, research ship tech and survive stellar anomalies on the way to a habitable exoplanet.
Tidal Proof
Drag the Moon around a water-covered Earth and serve harbor contracts in this two-bulge tide simulator: steer lunar and solar bulges, ride storm surges and chase perigee for king tides.
Tilt Shift
Set axial tilt and orbital eccentricity, launch the year and keep two crop hemispheres inside the habitable band: a seasons simulator that proves lean, not distance, rules the weather.
Stellar Forge
Slide and fuse atomic nuclei up the periodic table from hydrogen to the iron limit, then ride the supernova spray of gold and uranium.
Fossil Foundry
Fund dig-site expeditions through stacked strata, assemble skeletons from real bones and curate era-accurate museum exhibits while critics audit your placards.
Lunar Lookout
Steer the Moon around Earth to match real moon phases in the night sky, swat away shadow imps selling the Earth's-shadow myth, decode rise-and-set clues and nail eclipse line-ups across an 18-night expedition that rolls into an endless marathon.
