Solar Express is a realistic, yet casual spaceflight simulation game.
Start flying your rocket immediately (no building required), with enough delta-V to visit every planet in the solar system.
Navigate using a heads-up display optimized for phones.
Dock with space stations using your maneuvering thrusters.
Do powered landings on the surface of moons and planets.
Deliver supplies between planets and space stations around the solar system.
Real orbital mechanics, real 3D simulation, real programmer art, real nerdy. :)
