Turn your device into a complete space command center. EarthGaze puts the entire sky in your hands. Point your phone up and watch planets and stars snap into focus, oriented live to exactly where you're pointing. Track the ISS, Tiangong, and Hubble across a spinning 3D Earth. Catch a rocket launch the second it lifts off. Get an aurora alert before anyone else in your neighborhood looks up. This is mission control, reimagined for your pocket. Built with a clean style inspired by real mission control dashboards, EarthGaze brings together ten distinct tracking layers into one app. KEY FEATURES STARGAZE — LIVE NIGHT SKY VIEWER Point your phone at the sky and watch it come alive. StarGaze tracks the Sun, Moon, planets, and bright stars in real time as you move — tap anything you see for its exact position, brightness, and distance, plus whether you'll need the naked eye, binoculars, or a telescope to spot it tonight. A guided arrow walks you straight to any target. Check tonight's moon phase, true dark-sky window, and a live observing-conditions briefing before you even step outside — then plan ahead with a full 7-day sky outlook. 3D ORBITAL POSITION RADAR Monitor the International Space Station (ISS), the Tiangong Space Station, and the Hubble Space Telescope on a fully interactive 3D virtual Earth, with live trajectory lines showing exactly where each one is headed next. Use the live target selector dock to focus the camera and smoothly track any of the three across continent and ocean grids in real time. LIVE SATELLITE TRACKER See exactly when satellites like Starlink trains and the International Space Station (ISS) will fly over your house. The app finds your location automatically, but you can also type in your city manually if you prefer. GLOBAL LAUNCH CALENDAR Access a complete schedule of upcoming rocket launches from SpaceX, NASA, Rocket Lab, and agencies worldwide. Tap any flight to view the vehicle type, launch pad location, destination orbit, and live status updates. LIVE COUNTDOWNS & STREAMS Watch real-time countdown clocks tick down to the exact second of liftoff, and access direct links to live video streams straight from the launch screen so you never miss a launch. GEOMAGNETIC AURORA ALERTS Track the global Kp-index and view your immediate local aurora visibility chance in plain English. A dynamic briefing system evaluates active weather data alongside solar storm metrics to tell you exactly when conditions are optimal to look up. HUMANS IN SPACE ROSTER See who is currently living off-planet. View a live count and detailed list of every astronaut currently in orbit, with real photos and nationality, organized by whether they are stationed on the International Space Station or the Tiangong Space Station. NEAR-EARTH OBJECT TRACKER Monitor deep space activity with an updated tracking list for passing asteroids. Tap any record to inspect close-approach distances and flyby velocity calculations. METEOR SHOWER CALENDAR Track upcoming annual meteor shower peak dates. The app calculates optimal observation windows shifted directly to your location so you know exactly when to look up. EARTH WATCH Browse live NASA satellite imagery of Earth, updated throughout the day — jump straight to today's shot nearest your own location, or explore anywhere else on the planet. Also new: Home Screen and Lock Screen widgets, plus a Live Activity that shows your next launch or pass counting down in real time — right on your Lock Screen, no need to open the app. LOCALIZED TO YOU Every satellite pass, launch time, meteor shower peak, and sky position is calculated and personalized to your exact local time zone and physical location — nothing generic, everything pointed straight at your patch of sky.
