2D Flight Dynamics vs Star Map Night Sky

Take controls of an aircraft and explore its dynamic modes. Observe how deflecting control surfaces changes the overall forces on the aircraft.

SpaceUtil is a star map with AR that helps you find constellations, explore a 3D solar system, follow the ISS tracker live and see where Voyager is right now. The whole night sky in one astronomy app, with no account, and almost everything computed on your device without an internet connection. ■ AR STAR MAP AND SKY VIEWER • Point your phone at the sky to see the stars and constellations in that direction. • 120,000 stars and all 88 constellations with lines, names and artwork. • AR mode overlays the sky chart on your camera view. • Red night mode for comfortable stargazing in the dark. • Search for a star, planet or constellation and an arrow guides you to it. • Rewind or fast-forward time to see the sky on any date. ■ 3D SOLAR SYSTEM • An orrery with the Sun, the eight planets and major moons in their real positions. • Rotate and zoom with your fingers, and tap a planet for its story. • Live distances to each planet, Jupiter's four big moons and Saturn's rings. • Follow conjunctions and planet alignments. ■ LIVE ISS TRACKER • See where the International Space Station is right now on a 3D globe and a world map, updated every second. • Visible pass predictions for your location with time, direction and altitude. • A sky-path view of each pass. ■ WHERE ARE VOYAGER 1 AND 2? • Follow the two farthest human-made objects on a 3D map of the solar system. • See their current distance from Earth, computed on your device from public space-agency reference data. ■ TONIGHT • A briefing on tonight's observing conditions based on the moon phase and twilight times. • 5 objects worth looking at right now. • Sun, moon and planet rise and set times. • Civil, nautical and astronomical twilight. ■ MOON, ECLIPSES, METEOR SHOWERS • Moon phase calendar and lunar age. • Upcoming solar and lunar eclipses. • Every major meteor shower with its peak night and how bright the moon will be. ■ ASTROPHOTOGRAPHY HELPERS • 500-rule exposure calculator. • Milky Way planner. • Golden hour, blue hour and moonrise direction. ■ LEARN AND PLAY • Constellation myths and a space quiz. • The sky on your birthday and light travel time. • Light-year, AU and parsec converter. • An exoplanet catalog. • An observation log with badges. ■ GETTING STARTED • Open the star map and hold your phone up toward the sky. • Switch on AR mode to see constellation lines over the camera image. • Turn on red mode once you are outside in the dark. • Search for a planet or star and follow the arrow. • Check Tonight before heading out. ■ WHO IS IT FOR? • Stargazers identifying stars and constellations with AR. • Space fans tracking the ISS, the Voyager probes and planetary alignments. • Astrophotographers planning Milky Way shots. • Anyone learning about exoplanets, myths and moon phases. ■ TIPS • Use time controls to preview the sky on an eclipse date. • Check how bright the moon will be before a meteor shower peak night. • Log what you observe to collect badges. ■ FAQ • Do I need an account? No. There is no account and no cloud. • Does it work offline? Almost everything is computed on your device. • Is the camera image saved? No, never. • Are there ads? A single banner ad at the bottom of the screen supports development. No full-screen or video ads. ■ PRIVACY AND PERMISSIONS • Location is used only on the device to align the sky map. • The camera powers the AR view, and its image is never captured, stored or sent anywhere.
