An interactive lunar atlas

Explore the Moon in detail

A set of observation and learning tools built around an interactive lunar globe.

Interactive 3D globe

Control the view with touch gestures. Choose uniform lighting, phase simulation, or calculated lighting for the current time.

Object catalog

Search for lunar features, show labels and borders, and explore coordinates, diameters, and available descriptions.

Terrain and landmarks

View elevation data, enhance relief near the day-night boundary, and use the coordinate grid and lunar rotation axis.

Observation planning

Choose a date and location to calculate sunrise, culmination, and sunset for the Sun and Moon, with altitude and azimuth.

Lunar calendar

See the Moon’s phase and illumination for each day of a selected month.

The main tools, catalog, and reference materials are available offline and without registration. Set an observing location manually or use GPS; coordinates are stored on your device and used in calculations. Internet access is needed to open external links.

For everyone from first-time Moon explorers to astronomy enthusiasts, observers, and educators.

Google Play testing

Android only. An iPhone version will come later.

To make 3D Moon Atlas available to everyone on Google Play, I need to complete a closed test and then apply for production access. For this developer account, at least 12 testers must stay opted in continuously for 14 days. Your participation helps meet that requirement and lets me check the app on real Android devices. Google Play reviews the production request separately, so completing the test does not automatically make the app public.

Open the test link while signed in to the Google account whose email you sent, then join the closed test.
Install the app on Android and try the 3D globe, object catalog, lunar calendar, and observing tools.
Stay opted in to the test for 14 consecutive days. If you notice a bug or something confusing, message me by email, Telegram, or Threads.

Message me the email address for the Google account you will use in the test on Telegram or Threads. I will add it to the tester list and send you the link to join.
