Construct rockets, aircraft, and more to explore intricately detailed 3D planets.

This free-to-play version includes most of the Complete Edition's content, with additional features available for purchase as three separate bundles directly within the app. For those who prefer a single payment option, find "Juno: New Origins Complete Ed." on Google Play.

AEROSPACE SANDBOX

Juno: New Origins is a 3D aerospace sandbox where you build and test rockets, planes, vehicles, and other creations using customizable parts, all within a realistic physics environment spanning land, sea, air, and space.

CAREER MODE + TECH TREE

Manage your own aerospace company and advance by earning money and tech points. Complete hand-crafted and procedural contracts for endless gameplay variety. Achieve milestones and explore landmarks to gain tech points and unlock new technologies via the tech tree. Interactive tutorials guide you in building and operating rockets, cars, and airplanes.

RESIZE AND RESHAPE PARTS

Customize fuel tanks, wings, cargo bays, fairings, and nose cones with intuitive tools. Resize solar panels, landing gear, pistons, and jet engines to suit your designs. Apply custom paint colors and adjust reflectiveness, emissiveness, and texture styles.

DESIGN ROCKET AND JET ENGINES

Fine-tune engines by modifying the power cycle, combustion pressure, gimbal range, fuel type, and nozzle performance and appearance. Optimize engines for powerful lift-offs or efficient vacuum operation for interplanetary trips. Engine performance affects visual details, like exhaust expansion or contraction relative to atmospheric pressure. Shock diamonds may look impressive but indicate suboptimal performance. Alternatively, use pre-built engines and launch right away.

PROGRAM YOUR CRAFTS

Use a drag-and-drop code block system to program your crafts for telemetry logging, automation, and custom MFD touch screen design. Vizzy, a programming language built for Juno: New Origins, helps expand your craft's capabilities while teaching programming, math, and physics.

REALISTIC ORBIT SIMULATION

Experience accurate orbital simulations with time-warp features to shorten travel times between planets. Use the Map View to visualize orbits, plan maneuvers, and set up encounters with other planets or satellites.
