Advanced Space Flight is a realistic space simulator for interplanetary and interstellar travel. It is the only space simulator available that takes into account relativistic effects during interstellar flight. Besides simulating space flight this app can also be used as a planetarium, with all known planets shown in real scale with their accurate keplerian orbits. It can also be used as a star chart and exoplanet explorer, showing all solar systems with confirmed exoplanets within 50 light years from the Sun. This is the only app where you can get a sense of the true scale of the Universe, zooming out throught thousands of galaxies and galaxy clusters until you see the entire observable universe in your screen. Locations: - All Solar System planets plus 5 dwarf planets and 27 moons - All confirmed exoplanetary solar systems within 50 light years from the Sun, making a total of over 100+ exoplanets. - Over 50+ stars, including main sequence stars like the Sun, red dwarfs like TRAPPIST-1, white dwarfs like Sirius B, brown dwarfs like 54 Piscium B, etc. - Experience the full scale of the Universe: you can zoom out from a few meters to billions of light years, until you see the entire observable universe in your screen. Flight Modes: - Realistic Flight: Travel using optimized trajectories, calculated based on the orbital parameters of the origin and destination planets to minimize fuel usage. These are the kind of trajectories that would be used in a real space mission. - Free Flight: Take manual control of a spaceship in space, activating the engines as you see fit to achieve your goals. Spaceships: Advanced Space Flight features several spacecraft, based on present and future technology: - Space Shuttle (Chemical Rocket): Designed in 1968-1972 by NASA and North American Rockwell. It has been in service from 1981 to 2011, making it the most successful reusable spacecraft ever built. - Falcon Heavy (Chemical Rocket): Designed and manufactured by SpaceX, made its first flight in 2018. - Nuclear Ferry (Nuclear Thermal Rocket): Designed in 1964 by Ling-Temco-Vought Inc. - Lewis Ion Rocket (Ion Drive): Designed in a 1965 study by the Lewis Research Center. - Project Orion (Nuclear Pulse Propulsion): Designed in 1957-1961 by General Atomics. Some early prototypes were built before the project was abandoned after 1963. - Project Daedalus (Fusion Rocket): Designed in 1973-1978 by the British Interplanetary Society. - Antimatter Startship (Antimatter Rocket): First proposed in the early 1950s, the concept was further studied after advances in antimatter physics in the 80s and 90s. - Bussard Ramjet (Fusion Ramjet): First proposed in 1960 by Robert W. Bussard, design was improved in 1989 by Robert Zubrin and Dana Andrews. - IXS Enterprise (Alcubierre Warp Drive): Based on a concept design fom NASA designed in 2008 and popularized in 2015, it was the first serious attempt to design a superluminal spacecraft. Artificial Satellites: Several human-made satellites are present in the app: - Sputnik 1 - Hubble Space Telecope - Internation Space Station - Kepler Space Observatory - Transiting Exoplanet Survey Satellite (TESS) - James Webb Space Telescope Effects: - Atmospheric light scattering effects, making atmospheres look realistic both from space and from the surface of planets. - Planetary clouds that move at different speed than the surface. - Clouds in tidal-locked planets form giant hurricanes, caused by the Coriolis force. - Stars with volumetric corona and lens flares. Star color determined by surface temperature. - Planetary rings with realistic light scattering and real-time shadows from the planet. - Realtivistic effects when travelling close to the speed of light: time dilation, length contraction and relativistic doppler effect.

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. 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.

Verdict

The call

The clearest difference is update cadence: Juno at monthly against Advanced Space Flight's every 4 months. Juno also leads on ratings volume (1.2K vs 40) and chart position (#187 vs unranked). Advanced Space Flight's advantage is price ($4.99 vs $6.99). On rating, review sentiment, ads and in-app purchases there is nothing between them.

Advanced Space Flight costs $4.99 and Juno $6.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.3 for Advanced Space Flight against 4.4 for Juno. That said, the two scores are not equally well evidenced: Juno has 1.2K ratings behind it against 40, so its average is the more settled of the two. Written reviews are what separate them: 85% of Advanced Space Flight's written reviews are positive against 78% of Juno's.

UpkeepUpdate frequency

Advanced Space Flight ships an update every 4 months, Juno monthly. Both last shipped on October 24, 2026.
