ORBIT 1969

Can you thread an asteroid field with just three numbers? Pick a heading on the 360° compass, key in fuel and burn time, then hit Burn on your retro flight console.

Every burn is a decision.

A distant signal has broken the silence. Take the helm of Odyssey and trace it across 40 space-navigation missions in a fictional expedition inspired by the spirit of 1969.

Choose your heading, commit your fuel and set the burn duration. Watch your plan unfold, then prepare the next command while the ship is still flying. Reach the destination with as little fuel as you can.

THINK YOUR WAY THROUGH SPACE Thread asteroid fields, survey distant beacons and work around gravity, moving hazards and shifting currents. Longer routes demand careful course changes and enough fuel for the final approach.

40 MISSIONS. MANY DIFFERENT WORLDS. Travel from lunar orbits to the red landscapes of Mars, icy passages, planetary rings and the outer dark. Follow a story told through recovered transmissions, with atmospheric music for every mission.

YOUR COURSE, YOUR CHALLENGE Easy offers more room to learn. Hard tightens the fuel budget and asks you to enter every command afresh. Improve your own records, or optionally share your best flights on mission-by-mission online rankings. Fuel comes first; ties are decided by fewer commands, then shorter flight time.

A COCKPIT THAT FITS Play on iPhone and iPad, with layouts for both iPhone Duo displays and a dedicated cockpit when Duo is half open. Pinch to zoom, drag to explore and double-tap to return to the automatic camera.

LEARN AT YOUR OWN PACE A visual first-flight tutorial introduces the three controls. Optional Kids Mode reveals a compass guide when you hold a point on the map, helping you estimate a heading while leaving the decision to you. Choose kilograms, pounds or US gallons for fuel entry.

Play the missions without an account. Sign in with Apple is optional for online rankings, where you choose a unique callsign.
