Interactive 3D universeOrbit a living cosmos

On a computer, open the universe and orbit planets on real paths. You can zoom, pan, and find cosmic elements such as a whale shark, a stargate, and a black hole. The marketing demo on this page lets you try the motion without an account.

After you create an account and log a dream, that night can appear as a living orb in the universe. Each planet also opens a journal room, so exploration and writing sit in the same cosmos.

Phones are honest: the full 3D universe is desktop-first. After signup on a narrow screen, Mercury 91 opens Daily Orbit, with dreams, stars, and other touch-friendly rooms. Native apps are on a waitlist. This page is not an apology. It is the map.

It is for people who want presence in a place, not another feed to scroll. Explorers, dreamers who want to see their nights in space, and anyone who journals better when the room feels alive.

If you only have a phone today, start with dreams, stars, and Daily Orbit. Come back on a computer for the full solar system. The account is the same.

This experience is part of Mercury 91's living universe. Walking in to look around costs nothing: you can orbit the planets, see who else is present, and read public stars and dreams without paying. Membership is what lets you create and keep things, at $3.99/month for new members, cancellable anytime.

If a membership ever lapses, nothing you made is taken from you. You keep reading, editing, and deleting your saved work. Creating new entries and entering Forest pause when paid access ends; both resume the moment you rejoin.

If you already bought Mercury 91, nothing changes. Your lifetime access stays yours at no further cost, forever. You will never be asked to subscribe, and nothing you can open today moves behind the monthly price.

New members $3.99/month. Cancel anytime. 14-day money-back. Existing lifetime members keep lifetime access.
