Gravity Run: Beyond Earth

Hold to fire your engine. Let go to coast. Swing around planets to steal their speed. Gravity Run puts you in a small spaceship in the real Solar System. Every planet and moon is where it really is today, pulling on you with its real gravity. There are no tracks and no autopilot: just you, your fuel and some very big objects. SLINGSHOT THROUGH SPACE • One-touch flying: hold anywhere and the engine pushes you towards your finger. The farther your finger is from the ship, the harder it pushes. • Dive close to a planet and it flings you onwards. Hit the gold sweet spot for a PERFECT slingshot and a full tank. • A dotted line shows where you'll coast. It turns red before a crash. • Tap the minimap for Mission Control: your path, the target's arrival point and the objects ahead. LEARN REAL ORBITS, THE FUN WAY • Flight School: 13 short coached lessons, from your first push to a Jupiter gravity assist. • Missions to every planet, with launch windows computed from the real sky. • Journeys: multi-leg flights that carry on from where you ended. • Historic missions: fly Apollo 11, Voyager 2 and New Horizons on the dates they really launched. A NEW SKY EVERY DAY • Today's Sky: one mission a day on the planets' real positions. Keep your streak going. • Escape: reach the Sun's escape speed and leave the Solar System. How few days can you do it in? • Optional sky alerts tell you when a launch window opens or a planet is closest to Earth. EXPLORE AND COLLECT • The Codex: 49 entries for the Sun, planets, 35 moons, the asteroid belt and historic missions, each with real NASA photos, facts and stories. Unlock them by flying close. • Earn stars, unlock faster ships in the Hangar and collect 18 awards. • Share your best flights. Made for curious minds of all ages. Works completely offline.
