Orbit. Land. Explore.
Sol Program is a free browser-based space program game. Launch from Earth, master orbital mechanics, and land on the Moon, Mars, Phobos, and Europa. Upgrade your ship with better engines, fuel tanks, heat shields, and navigation computers. Complete 7 missions from first orbit to the final return from Europa. Arcade controls with Kerbal-style progression. No download required.
Complete missions to earn credits. Start by reaching Earth orbit, then land on the Moon, Mars, and beyond.
Gravity from all celestial bodies affects your ship. Plan burns carefully — fuel is limited.
Upgrade between missions: Nav Computer shows trajectory, better Landing Gear gives more tolerance.
Star ratings depend on fuel efficiency and time. 3-star runs earn the most credits.
Sol Program is a free browser-based space program game where you pilot spacecraft through orbital mechanics, completing missions from Earth orbit to Europa and back.
Yes, Sol Program is completely free to play in your browser with no downloads required.
Gravity from all celestial bodies affects your ship realistically. You plan burns to transfer between orbits and land on planets. A trajectory preview and prograde/retrograde markers help you navigate. Controls are arcade-style but the physics rewards learning real orbital concepts.
You can visit Earth, the Moon, Mars, Phobos, Jupiter, and Europa across 7 missions that progress from simple Earth orbit to a round trip to the outer solar system.
