Read full description

Fly to the Moon, visit Mars, and relive the Apollo journeys in an immersive spacecraft cockpit. Start with the free Earth-to-Moon journey; Apollo replays, Mars, and more are available with a one-time Full Access purchase. RELIVE SIX APOLLO LANDINGS Follow Apollo 11, 12, 14, 15, 16, and 17 from launch through their lunar adventures and return. Watch the spacecraft change through key mission stages, follow the descent, and explore mission events and lunar surface stories at your own pace. A VIEW INTO LUNAR HISTORY The final descent leads into a fixed exterior scene made from that mission's later EVA archival photography. See the lander and lunar landscape in historical detail. These images are clearly labelled archival stills, not recordings of the touchdown moment. YOUR SEAT IN SPACE Switch between cockpit, chase, close-up, and overview views during flight. Use the time-warp dial, pause, or continue as the journey unfolds. Dedicated iPad layouts support portrait and landscape. MAKE THE JOURNEY YOURS Save completed journeys in your on-device Flight Log. Create a mission card with your name or a portrait, then share it using the system share sheet. Free cards include a download QR code; Full Access cards omit it. START FREE, EXPLORE FURTHER The guided Earth-to-Moon journey and MESSENGER historical replay are free. A one-time Full Access in-app purchase unlocks Apollo and other additional mission replays, Mars, more destinations, and advanced controls. No subscription. Some journeys and optional assets need a download and internet access. Solar Journey is an educational spaceflight experience. Historical replays combine mission-report events, source data, and disclosed reconstruction; camera framing and attitudes are visualizations, not live telemetry or flight training. Planned journeys are educational models, not operational flight plans. Data-source credits do not imply agency endorsement.
