About this game

After six years of development, what began as a simple rocket simulator has become a comprehensive aerospace sandbox in which you can bring to life anything you can imagine - from rockets, airplanes, and cars to entire planets. Over time, the more we added, the more SimpleRockets 2 outgrew its name. With much consideration we have decided to change the name to "Juno: New Origins" - a title that symbolizes a new start.

AEROSPACE SANDBOX
Juno: New Origins is a 3D aerospace sandbox where players can use customizable parts to construct and test rockets, planes, cars, or anything they can imagine in an environment with realistic physics across land, sea, air, and space.

CAREER MODE + TECH TREE
Take control of your own aerospace company and earn money and tech points as you progress through the game. Complete contracts to earn money, and discover a mixture of hand-crafted and procedural contracts that offer countless hours of new gameplay. Conquer milestones and explore landmarks to earn tech points and unlock new technology in the tech tree. Interactive tutorials are available to show how to build and operate rockets, cars, and airplanes.

RESIZE AND RESHAPE PARTS
Stretch and shape fuel tanks, wings, cargo bays, fairings, and nose cones with easy-to-use tools that help you create exactly what you want. Resize solar panels, landing gear, pistons, jet engines, etc to fit your needs. Paint your craft custom colors and tweak their reflectiveness, emissiveness, and texture styles.

DESIGN ROCKET AND JET ENGINES
Engines can be adjusted in a myriad of ways, such as changing the power cycle, combustion pressure, gimbal range, fuel type, and adjusting nozzle performance and visuals. You can customize an engine to be a power house for lift off, or to be a super optimized vacuum engine that maximizes Isp for interplanetary travel. The engine's performance affects its visuals in flight too as shown by the exhaust's expansion or contraction based on its interplay with the atmospheric pressure. Shock diamonds are pretty but they are a symptom of suboptimal engine performance! If you don't care about any of this, then you can just attach a pre-built engine and hit launch!

PROGRAM YOUR CRAFTS
Easily drag and drop code blocks to program your crafts to log telemetry, automate them, design your own MFD touch screens, etc. With Vizzy, a programming language designed specifically for Juno: New Origins, you can expand the capabilities of your crafts while learning programming, maths, physics, etc.

REALISTIC ORBIT SIMULATION
Orbits are realistically simulated and support time-warp so you don't have to wait several months to reach another planet. The Map View makes it easy to see your orbits and plan future burns, which you can use to set up future encounters with other planets or satellites.

DOWNLOAD CRAFTS, SANDBOXES, AND MORE
Download from a huge collection of user-uploaded crafts, sandboxes, and planets on SimpleRockets.com. Upload your own crafts and sandboxes and share them with the community. Rise through the ranks from a white level builder to a gold level builder and beyond.
Build rockets, airplanes, and more and explore highly detailed 3D planets.

I wish the mobile version was more in depth. you have to open a hidden panel to change the color of any build you you can't just go "oh I want it to be red" you have to put in a series of numbers. and no the numbers aren't publicly released so you have to go through every single number from 1-350 and figure out what every number does. not to mention if you want a fuel tank to be slender or wider than it is tall you have to open the same hidden panel and it crashes pretty often but it's alr

The game is fun and the planet studio is brilliant for those who want to let their creativity run wild but i feel like there should be more to it like a setting the could determine if a planetary object should able to emit light like a star instead of one central star there could be multiple as interstellar systems and a maximum distance where the stars light could reach and make the craft dark instead of lit by the star by a impossibly far distance to add slightly more realism.

The game itself is really good but it's frustratingly full of bugs, pretty disappointing.
