Evaluation

Spaceflight Simulator has been in Early Access on Steam since February 17, 2022 and remains in that state. The game continues to receive substantial updates from Team Curiosity. The most recent major release, version 1.6 (the "Full Solar System Update"), shipped on March 31, 2026 and added a large number of new planets and moons (including Saturn, Uranus, Neptune, Pluto, and their moons), water on Earth, texture reworks, a mod loader, and new planet-editing tools — a very significant content addition. A news post on April 11, 2026 highlighted the update with a video showcase. On April 10, 2026, the developer published an update announcing Spaceflight Simulator 2, confirming the studio is actively working on a next installment. This signals that Team Curiosity remains a healthy, active studio. Looking at the broader post-launch history, the game has received a steady stream of feature patches (June 2022, October 2022) and a notable update in June 2023 (version 1.5.10), leading up to the large 1.6 update in March 2026. This pattern of continued development across more than four years of Early Access confirms the game is receiving ongoing substantial content work. No announcement of a 1.0 release or completion of development has been made.

About this game

Note: STEAM version already includes Expansions/Packs/Bundle.

EXPLORE SPACE

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.

EASY-TO-PICK UP, HARD-TO-MASTER

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.

REAL-WORD PHYSICS

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.

BUILD YOUR WORLD

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.

PARTS, PARTS, PARTS

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)

● Skins (to personalize your rocket)

WHAT TO EXPLORE

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
