From the launchpad to the Moon

A whole journey.
One step at a time.

The big button always has your next job. Fire the engine, separate a stage, dock, or head home. Switch into the cockpit to watch the world from your own window.

Fly Shuttle, Starship, SLS, or Saturn V on three adventures: Earth & home, Moon, and Space Station. Tap Inside during flight to explore your ship for as long as you like; the flight waits until you return.

Float through the station’s living quarters, cargo bay, research module, and cupola. On the Moon, hop into a rover, head for distant landmarks, and explore the rooms of your Moon base. Switch to the helmet view and collect photographs along the way.
