Juno: New Origins (formerly SimpleRockets 2) is an absolute masterclass in aerospace simulation on mobile. As someone who has spent hundreds of hours in Kerbal Space Program, I am floored by how much depth Jundroo managed to pack into this experience. The 'Complete Edition' isn't just a label; it’s a fully realized universe where you don’t just fly rockets—you architect every single bolt and fuel line. The procedural part system is the real star here. Instead of being locked into preset sizes, you can stretch, taper, and reshape fuel tanks and wings to your heart's content, allowing for sleek, realistic designs or absolute behemoths.
The addition of a full Career Mode transforms it from a sandbox into a compelling game. Managing a space agency, taking on contracts, and progressing through a dense tech tree provides a sense of purpose that keeps you coming back for 'just one more launch.' The visual programming language, Vizzy, is another highlight. It allows for complex automation—like landing boosters autonomously—that feels incredibly rewarding to execute. While the learning curve is steep, the interactive tutorials are excellent. If you have even a passing interest in space, engineering, or physics, this is an essential purchase.

Version 1.3.206Mon Dec 15 2025
Maintenance Update
Bring to life anything you can imagine from rockets and airplanes to cars and more. Automate them with a visual programming language. Explore 3D planets and download more from the community. Share your creations online. Complete contracts, conquer milestones, and unlock technology in the newly added Career Mode.
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.
