Walking on Mars
- A 70 kg explorer would feel like 26 kg.
- A jump that clears 50 cm on Earth would reach about 132 cm.
- Each jump floats for seconds before you drift back down.
Landmarks in the game
- Olympus Mons (scaled down): Olympus Mons is about 22 km high, nearly three times Everest, the tallest known volcano in the solar system.
- Valles Marineris canyon (scaled down): Valles Marineris is a canyon system over 4,000 km long and up to 7 km deep, far larger than the Grand Canyon.
Real maps, real physics. Earth, the Moon and Mars use real NASA surface maps. Gravity, temperature and air pressure are the real values, and they change how you move, what you hear and how long your suit lasts.
