POSITION
FOURTH FROM THE SUN
Mars orbits beyond Earth, in the outer inner solar system. It's about half Earth's size and takes 687 Earth days to complete one orbit. This red planet captivates astronomers and explorers because it might have been habitable billions of years ago — and humans could walk there someday soon!
RUSTY!

GEOLOGY
IRON OXIDE = RED COLOR
Mars is rusty! The planet's surface is covered in iron oxide (rust) which gives it that distinctive red color. The landscape is dominated by giant canyons, massive volcanoes, polar ice caps made of frozen CO₂ and water ice, and evidence of ancient river deltas. Scientists believe liquid water once flowed across Mars!

EXTREME TOPOGRAPHY
Mars has the most dramatic landscape features in the solar system! The massive volcano Olympus Mons towers 21 km high (2.5 times higher than Mount Everest). The colossal canyon Valles Marineris stretches over 4,000 km — longer than the Grand Canyon! Channels suggest water once carved the landscape. A geological wonder world!

PAGE 4 OF 5 — SEASONS ON MARS
CLIMATE
MARS HAS SEASONAL CYCLES
Like Earth, Mars experiences seasons! It tilts on its axis, causing seasonal temperature changes. Summer in Mars's northern hemisphere can reach -20°C (still freezing!), while winter drops to -140°C. The polar ice caps expand and shrink with the seasons. Dust storms rage across the surface during certain times of year, turning the sky reddish-brown!

EXPLORATION
THE FUTURE HOME FOR HUMANS
Mars fascinates space agencies and explorers worldwide! Rovers like Curiosity and Perseverance search for signs of ancient microbial life. Many scientists believe humans could establish a colony on Mars within the next 30 years. Why Mars? It has water ice, a 24.6-hour day similar to Earth, and it might have once been habitable. Mars is our next great adventure!
