Ready when you are.

Open Choose your rocket to select Shuttle, Starship, SLS, or Saturn V. Swipe the model to turn it, then tap LET’S FLY. Choose Earth & home, Moon, or Space Station to begin your journey.

There is one local space program on your device. StageSep works offline on iPhone and iPad with iOS or iPadOS 17 or later; no account or connection is needed to play.

Tap LAUNCH, then use the large button for the current action. When it says HOLD, keep your finger down to run the engine and release to stop. A new stage needs a fresh press. Travel and docking sometimes continue automatically.

On the Moon, engine thrust slows your descent. Let go to descend and hold to slow down. Guidance helps with landing, and REFUEL appears if the landing tank runs out.

For a different flight control style, pause and enable Tap engine on / off. Tap once to run the engine and again to stop. This setting changes the flight engine; exploration has its own movement controls.

Shuttle glides toward a runway. Tap GEAR to lower the wheels, then watch the guided flare, touchdown, and rollout. Starship descends belly-first: tap LAND to begin the assisted flip, landing burn, and tower catch. The fuel gauge shows its landing reserve. SLS and Saturn V return in capsules with parachutes and an ocean splashdown.

Guidance handles the precise landing timing. You can still pause or visit Inside during the return. Our Moon-ready Shuttle and returning Starship tower catch are playful future capabilities.

Tap Cockpit during flight to sit inside the spacecraft. Drag the window to look around; this changes your view, not the flight path. Tap Outside to return to the exterior camera.

Both views show the same altitude or destination distance, speed, mission time, and available fuel. These are simplified game instruments for a time-compressed journey.

Tap Inside during a flight to explore the flight deck, observation area, crew quarters, and engineering. The flight and mission clock pause for your entire visit, with no time limit. Use the movement pad to float around, swipe to turn the camera, and use the up and down buttons to change height.

Look out the window, sleep in a bunk and wake up, or inspect engineering. Tap the back arrow to return to the flight where you left off.

Build and rearrange your station by choosing a module and an empty port, sliding toward it, and tapping LATCH. Then choose INSIDE to float through the station.

The movement pad takes you through living quarters, a cargo bay, a research module, and the panoramic cupola. Use the up and down buttons to float at different heights, and swipe to turn your view. Move close to an exhibit to reveal its action: look out over Earth, tend the garden, try an experiment, move cargo, or spin the gyroscope. The back arrow returns to your station.

After landing, choose WALK. Use the movement pad to explore on foot, hop in low gravity, or get into the nearby rover and drive. Use the map and destination guide to explore distant landmarks. There is no exploration timer.

Enter the Moon base to visit its command room, greenhouse, science lab, crew quarters, and engineering. Try the nearby activities, or rest in a crew bed and wake up when you are ready.

Tap Helmet for a view through your visor, or Astronaut to see your explorer again. Swipe to look around. Tap Return and choose the Moon lander or Moon base to bring both you and the rover back. The back arrow returns to the mission so you can continue the trip home.

Tap pause for RESUME, MISSIONS, flight control style, Sounds, and Haptics. Sound and haptics can be switched off separately. Sound respects silent mode. Haptics depend on device support.

After pausing or returning from another app, resume and make a fresh input to continue. If there is no sound, check Sounds in the pause menu, silent mode, device volume, and the selected audio output.

With VoiceOver, activate a flight engine control once to start and again to stop. During Moon and station exploration, the directional controls also support short steps. The cockpit window supports adjustable actions to look around. StageSep also respects your system Reduce Motion setting for optional camera vibration.

Choose Continue on the opening screen when it appears to resume your saved journey on this device. The app does not synchronize saves between devices.

Take multiple photographs during your mission, Moon exploration, and station visit. Open the in-app photo library to review them with their capture date, local time, mission, and location. Helmet-view photographs show the world without the visor overlay. You can delete individual pictures from the library after confirming. Photographs stay in the app; they do not use your camera or add anything to your device’s Photos library.

Avoid deleting StageSep while troubleshooting: deleting it removes the local space program. Apple manages device backups, and support cannot retrieve an online copy of your save.
