Mars - Wikipedia
Mars is less dense than Earth, having about 15% of Earth's volume and 11% of Earth's mass, resulting in about 38% of Earth's surface gravity. Mars is the only presently known example of a desert planet, a rocky planet with a surface akin to that of Earth's deserts.
Mars Facts - Science@NASA
Mars is one of the most explored bodies in our solar system, and it's the only planet where we've sent rovers to roam the alien landscape. NASA missions have found lots of evidence that Mars was much wetter and warmer, with a thicker atmosphere, billions of years ago.
Mars - NASA Science
Mars is one of the easiest planets to spot in the night sky — it looks like a bright red point of light. Despite being inhospitable to humans, robotic explorers — like NASA's Perseverance rover and Mars Reconnaissance Orbiter — serve as pathfinders to eventually get astronauts to the surface of the Red Planet.
Mars | Facts, Surface, Moons, Temperature, & Atmosphere | Britannica
Mars is the fourth planet in the solar system in order of distance from the Sun and the seventh in size and mass. It is a periodically conspicuous reddish object in the night sky. There are intriguing clues that billions of years ago Mars was even more Earth-like than today.
Overview | Mars - NASA Solar System Exploration
Mars is the fourth planet from the Sun – a dusty, cold, desert world with a very thin atmosphere. Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes, and evidence that it was even more active in the past.

All About Mars | NASA Space Place – NASA Science for Kids
Mars is sometimes called the Red Planet. It's red because of rusty iron in the ground. Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons, and weather. It has a very thin atmosphere made mostly of carbon dioxide, nitrogen, and argon. People would not be able to breathe the air on Mars. Explore Mars!
Mars - Simple English Wikipedia, the free encyclopedia
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, nicknamed The Red Planet. Mars is a terrestrial planet with caps of water and carbon dioxide. [5][6] It has the largest volcano in the Solar System, and some very large impact craters. [5]
NASA’s Curiosity Rover May Have Solved Mars’ Missing Carbonate Mystery
New findings from NASA’s Curiosity Mars rover could provide an answer to the mystery of what happened to the planet’s ancient atmosphere and how Mars has evolved over time. Researchers have long believed that Mars once had a thick, carbon dioxide-rich atmosphere and liquid water on the planet’s surface. That carbon dioxide and water ...
