About this game

Rocket Foundry is a 2D spaceflight sandbox built around realistic orbital mechanics. Design modular rockets part by part, launch from a full-size Earth, and explore a 1:1 scale model of the solar system.

BUILD YOUR ROCKET

Create launch vehicles, landers, rovers, stations and experimental spacecraft with a flexible grid-based builder. Combine engines, fuel tanks, separators, fairings, docking ports, RCS, landing legs, parachutes, wheels and more.

Every part affects your vessel's mass, balance, fuel capacity and flight performance. Build carefully—or learn from a spectacular failure.

MASTER ORBITAL FLIGHT

Rocket Foundry simulates gravity and Keplerian orbital mechanics using double-precision calculations.

• Launch into orbit and perform accurate burns
• Plan transfers using manoeuvre nodes
• Track apoapsis, periapsis and spheres of influence
• Find transfer windows and rendezvous opportunities
• Dock spacecraft and assemble larger vehicles
• Use time warp to cross interplanetary distances
• Fly through atmospheres and land on planetary surfaces

EXPLORE A REAL-SCALE SOLAR SYSTEM

Travel through a solar system containing 76 celestial bodies with realistic sizes, distances, gravity and orbits. Launch from Earth, visit the Moon and Mars, explore the outer planets or attempt missions to asteroids and distant dwarf planets.

CAREER AND MISSIONS

Complete missions, earn research and unlock new technology as your space programme grows from its first launch to ambitious interplanetary expeditions.

CREATE, MODIFY AND SHARE

Rocket Foundry includes data-driven mod support and in-game authoring tools for creating custom parts, planets and surface structures.

Publish your best designs to the optional Community Hangar, discover reviewed rockets created by other players and download blueprints directly into your game.

The main single-player game can be played offline. An internet connection is required for Community Hangar features.
