Spaceflight Simulator

Spaceflight Simulator is a game where you design your own rocket from modular parts and launch it to explore space. You build, test, and refine your spacecraft, then fly missions that can reach orbit, attempt landings, and travel between planets using realistic physics.

Build Any Rocket You Can Imagine

You assemble rockets from parts and create anything from a simple booster to a multi-stage interplanetary craft. The game encourages experimentation, so you can redesign your vehicle after failures and keep improving until your build can handle the mission you want.

Accurate Physics and Orbital Mechanics

Spaceflight Simulator uses realistic rocket physics and orbital mechanics. You must manage thrust, staging, fuel, and trajectories to reach stable orbit and plan transfers. Success depends on efficient design and careful flight control rather than scripted shortcuts.

Open Universe with No Invisible Walls

The game doesn’t block you with artificial boundaries. If you can see something in the distance, you can travel there. This open approach makes exploration feel earned, because you reach destinations through planning and piloting, not by selecting a menu option.

Realistically Scaled Planets You Can Visit

You fly around a set of realistically scaled worlds and moons. You can attempt orbit, landings, and surface missions across multiple bodies, including:

• Mercury
• Venus (dense, extremely hot atmosphere)
• Earth
• Moon
• Mars (thin atmosphere)
• Phobos (rough terrain, low gravity)
• Deimos (very low gravity, smoother surface)

Recreate Famous Missions

Spaceflight Simulator lets you recreate launches inspired by real-world programs, including Apollo-style missions and modern SpaceX/NASA-style rockets. You can build vehicles that resemble your favorite historical or current spacecraft and try to match their mission profiles.
