Spaceflight Simulator is a rocket-building and launching game created by Štefo Mai Morojna. Players can create their own rockets and spacecrafts, then launch them into space.

The game was available only in English until 1.5 got released, introducing translations. The game is now available in multiple languages. The game is available in Android, iOS and Steam.


  • Realistically scaled planets
  • Realistic orbital mechanics
  • Open universe with no invisible walls


The first public version of the game is 1.0, released on the 30th November, 2017. After continuous updates and improvements, the latest version available is 1.5.5


The Sun, planets and moons listed here are present in the game and can be visited.

Celestial bodies

  1. Sun: Our home star where the 8 planets orbit
  2. Mercury: The planet closest to the sun; very similar to the moon; very difficult to explore
  3. Venus: The planet that has a thick and deadly atmosphere and has mountains and a few craters
  4. Earth: Our home; this is where rockets launch from
  5. Moon: Earth's natural satellite
  6. Mars: The Red Planet; half the size of Earth and has 2 small moons
  7. Phobos: The larger, inner moon of Mars with a porous terrain and low gravity
  8. Deimos: The smaller, outer moon of Mars that has a smooth terrain and no gravity
  9. Jupiter: The largest planet in the solar system; has 4 moons
  10. Io: The innermost Galilean moon; has many volcanoes
  11. Europa: The icy moon of Jupiter; easy to explore; has smooth terrain
  12. Ganymede: Hardest celestial body in the game; has rough terrain and large gravity
  13. Callisto: The outermost moon of Jupiter; has a cratered surface

Be in command of your own space program, from rocket design to interplanetary travel and achieve your dream of cruising through the cosmos in your custom spacecraft.

In Spaceflight Simulator, you will get to engineer your rockets, plan launches and flights, attempt landings, deploy payloads and explore new worlds.


You could be launching your first rocket within minutes, but landing it in one piece might be another story!

With so many parts to pick from, you will learn through trial and error how to build spacecrafts best adapted to each of your missions. You will have to master navigating through the Solar system and landing your vehicle on all the planets and moons, each with their own atmospheric and terrain conditions.


During the design phase, you will get to assemble your own launch vehicle from a wide variety of components and pair them with a multitude of engines, all modeled after their real-world counterparts. Each part possesses its own technical specifications (mass, aerodynamics, etc.) which will affect your rocket's behavior.

All engines accurately model thrust and fuel consumption affecting how much payload you'll be able to carry safely. You'll be able to create multistage vehicles, control how they separate and when secondary burn occurs in order to achieve the optimal trajectory.


Fuel your ambitions, launch satellites, build exploration rovers, space stations, multiple rockets into space. Your world is persistent and only your imagination is your limit.

Conquer the harsh conditions of the solar system, travel long distances and build your presence in space throughout multiple missions.


Each part is highly detailed and serves a particular purpose. They are all based on their real-world equivalent and allow you to recreate your favorite historical rocket.

  • Fuel tanks (20 sizes and configurations)
  • Engines and thrusters (6 propulsion systems and a reaction control system)
  • Aerodynamics (13 fairings with many nose and side cones)
  • Capsules, probes, payload systems, separators and docking ports
  • Landing systems (legs, parachutes, wheels)
  • Utilities (solar panels, batteries, electrical, structural)
  • Skins (to personalize your rocket)


Each destination is modeled accurately in terms of gravity pull and atmospheric conditions, offering a challenging landing experience every time.

  • Earth, your starting point
  • The Moon, Earth's celestial companion
  • Mercury, the smallest planet of our solar system and the closest to the Sun
  • Venus, Earth's inside neighbour with an extremely dense and hot atmosphere
  • Mars, the red planet with a thin atmosphere
  • Phobos, Mars' inner moon, with porous terrain and low gravity
  • Deimos, Mars' outer moon, with an extremely low gravity and a smooth surface
  • Jupiter, the gas giant with its thick atmosphere
  • Io, Europa, Ganymede, and Callisto. Each with their own terrain and landing difficulty

  • There is a knockoff game that looks like the original, but with a different picture, Chinese characters, and made by Unlimited Entertainment Studio.
  • The game is much simpler than other rocket games. Learn more[1]
