EXPEDITION 004 / THE SUNLIT PLAIN

Stand on
Mercury.

Walk an imagined cratered plain beneath a black sky — a giant Sun, hard shadows, and the silence of a world with no air.

THE EXPEDITION FIELD GUIDE

Take the long way home.

This is a small, freely explorable cratered plain, not a whole-planet simulation. The five observation points are different views of the same place; two of them can only be reached on foot.

Follow the amber guide dots and distance arrow. Walk up to a stop and press E or Discover to add it to your journal. Quick travel does not automatically record a discovery.

Moving around

You are exploring on foot as an astronaut. Walk with W A S D or the arrow keys; Shift gives a brisker pace. Press Space to jump, then wait to land before jumping again. Momentum carries you forward in the air. Drag to look, including down at your boots. Touchscreens have direction and Jump buttons. H hides notes; P opens photo mode; Esc closes it.

Disable head motion for a steadier view.
Same takeoff push, different fall. Mercury gravity is 3.7 m/s² — about 38% of Earth’s, close to Mars despite its smaller size.
Inside the suit: fan hum and conducted footfalls. Outside, Mercury is a near-vacuum — no air to carry wind or thunder. M toggles.

What you are seeing

Science meets imagination

Mercury is the smallest planet and the closest to the Sun, yet its gravity matches Mars because it is mostly a giant iron core. Dayside reaches about 430°C and night drops to −180°C. Mariner 10 and MESSENGER mapped its cratered face, lobate scarps, and strange bright hollows. Terrain and observation points are procedural art, not survey data.

Mercury has essentially no atmosphere — an exosphere too thin to carry sound. Outside the suit there is only silence; inside you hear the life-support fan and footfalls conducted through the body. Gravity is 3.7 m/s² — press G to compare with Earth.

Mercury has no moons and no air to dim the stars. The huge Sun dominates; Earth and Venus shine as small points. Click a bright body to learn more.
