Build and launch rockets, airplanes, and more to explore highly detailed 3D planets.

This is the free-to-play version, featuring most of the content from the Complete Edition. The remaining content is available for purchase as three individual bundles directly from within the app. If you prefer a one-time purchase, please check out "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, cars, and any other creation you can imagine. Experience realistic physics across land, sea, air, and space with fully customizable parts.

CAREER MODE & TECH TREE

Take control of your aerospace company to earn money and tech points. Fulfill a mix of hand-crafted and procedurally generated contracts for endless gameplay. Conquer milestones and explore landmarks to gain tech points for unlocking new technologies. Interactive tutorials will show you how to build and operate rockets, cars, and airplanes.

RESIZE AND RESHAPE PARTS

Use intuitive tools to stretch and shape fuel tanks, wings, cargo bays, fairings, and nose cones. Resize components like solar panels, landing gear, pistons, and jet engines to fit your design. Customize your craft with unique colors, reflectiveness, emissiveness, and textures.

DESIGN ROCKET AND JET ENGINES

Fine-tune every engine detail: adjust the power cycle, combustion pressure, gimbal range, fuel type, and nozzle performance. Design a powerful lifting engine or a super-efficient vacuum engine optimized for interplanetary travel. Engine performance affects visual effects in flight, with exhaust plumes expanding or contracting based on atmospheric pressure. Shock diamonds look impressive but indicate suboptimal performance! If you prefer simplicity, just attach a pre-built engine and launch.

PROGRAM YOUR CRAFTS

Effortlessly drag and drop code blocks to program your crafts. Log telemetry, automate systems, and design custom MFD touch screens. With Vizzy, a programming language built for Juno: New Origins, you can expand your craft's capabilities while learning programming, math, and physics.

REALISTIC ORBIT SIMULATION

Experience realistically simulated orbits with time-warp, so you don't have to wait months to reach other planets. Use the Map View to visualize orbits, plan maneuvers, and set up encounters with planets or satellites.
