IMPORTANT: This app is a simulator rather than a game. Don't download this app if you are looking for some fast-paced action game.

In this app you will find:
- All major planets and moons in the Solar System with their accurate keplerian orbits:
* Sun
* Mercury
* Venus
* Earth and Moon
* Mars and its moons Phobos and Deimos
* Jupiter and its major moons: Io Europa Ganymede Callisto
* Saturn and its major moons: Mimas Enceladus Tethys Dione Rhea Titan Hyperion and Iapetus

- Realistic space travel from Earth to the Moon and Mars
- Realistic calculation of fuel requirements using Tsiolkovsky Rocket equation
- Timeslider to accelerate/decelerate time. You'll also be able to run time backwards
- NEW! Free flight mode: take control of your spaceship with a limited amount of fuel. Experience the effect of gravity on your trajectories.

Get the full version and you'll get:
