What it would be like in Worldwalk imagined
Nobody has seen the surface of GJ 367 b. The game builds it from the real numbers above: you land on glowing iron-rich lava fields.
- Air: rock vapor · a guess. Surface pressure: almost none.
- A 70 kg explorer would feel like 65 kg.
- A jump that clears 50 cm on Earth would reach about 54 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.
