WORLD PROFILE / A red world. A different you.

Mars

A cold desert with a thin carbon-dioxide atmosphere. Survival begins with life support.

Known environmental science

Known science: Mars has low gravity and a very thin atmosphere dominated by carbon dioxide. Unprotected human respiration is impossible. Pressurized suits and shielded habitats are essential.

Long-term inherited changes to human anatomy on other worlds are unconfirmed. A gas percentage alone does not determine a face, skin color or body shape.
