What the developers have to say:

Why Early Access?

“As developers, we have a lot of ideas on how to improve the game but our opinions only go so far. That is why we strongly feel we need to hear your voices and let you, the players, decide what next big features should go into Spaceflight Simulator. Essentially, we want to focus our energy on content and gameplay which matter most to the community.

We will be listening to your feedback and engaging with players to fine tune our development roadmap.
We believe Early Access is a great platform for us to iterate and adapt quickly to player feedback.”

Approximately how long will this game be in Early Access?

“We estimate the Early Access period to roughly last from 9 to 12 months.”

How is the full version planned to differ from the Early Access version?

“The short answer is you will tell us! The long answer is we already have a bunch of potential features we would like to add to Spaceflight Simulator. We hope you will help us decide which features will go into the game through your feedback. We will roll out new features as soon as they are ready.

Below are some examples of what we already have in mind. Please understand that these features are not set in stone and may change or expand depending on what the community tells us.

- Advanced rocket builder mode
- New parts and skins
- Objective system and progression

Rest assured we are committed to adding content during and after the Early Access period but ultimately it will be your decision as to what makes the cut.”

What is the current state of the Early Access version?

“We believe the current state of the game is solid, essentially bug-free and already polished. The core mechanics, gameplay and graphics should not change much but continuous improvements are to be expected.

The Early Access period will be used to implement new major features and upgrades based on your feedback.”

Will the game be priced differently during and after Early Access?

“We are planning for the game to be a bit more expensive (around 20-30%) once it is promoted to Full Launch. We firmly believe in giving Early Access players a better deal for providing us crucial data and metrics throughout our development process.”

How are you planning on involving the Community in your development process?

“We will carefully read and consider all your reviews. Your feedback is invaluable as it helps us better understand how players interact and engage with the game. We also look forward to exchanging ideas with the community in Steam Discussions as well as our official Discord server.

As new features enter the production pipeline, we will make sure to let you know what we are working on and when to expect it. Finally, we are planning to specifically ask players to vote on features and development priorities.”

About This Game


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 rough 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 how terrain and landing difficulty
