Mars has an atmosphere, but astronauts cannot breathe it. Here’s what they would actually inhale, and how future missions could make it possible.

A clear look at what Mars rovers have revealed about the Red Planet’s geology, water history, climate, and habitability.

Mars is frigid, thinly atmospheric, and highly variable. Learn how hot and cold it gets, why temperatures swing so widely, and what missions actually measure.

Explore the key scientific reasons Mars lost most of its atmosphere and how solar wind, weak gravity, and a dying magnetic field reshaped the planet.

Mars offers a natural laboratory for studying habitability, extremophile life, and the conditions that may have shaped life on Earth.

Mars’s thin, dusty atmosphere makes entry, descent, and landing uniquely difficult, shaping every heat shield, parachute, and rocket burn.

Mars orbiters circle the Red Planet to map its surface, study climate, and relay data. Here’s how they work and why they matter.
