What it would be like in Worldwalk imagined
Nobody has seen the surface of LHS 475 b. The game builds it from the real numbers above: you land on bare, cratered rock with no air.
- Air: None (bare rock). Surface pressure: almost none.
- A 70 kg explorer would feel like 67 kg.
- A jump that clears 50 cm on Earth would reach about 52 cm.
- With almost no air, a hammer and a feather fall side by side, and sound cannot travel.
Pack the right suit. Choose 3 of 6 modules (cooling, heating, pressure hull, extra oxygen, radiation shield, jetpack), complete 3 surveys and get back to the lander before your oxygen runs out.
