Mars is the fourth planet from the Sun. The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.

2024年11月20日 · 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.

4 天之前 · 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.

2025年1月29日 · For over 60 years, NASA has been in pursuit of answering science's biggest questions – was, or is, Mars a habitable world? The key to understanding the past, present or future potential for life on Mars can be found in NASA’s four …

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.

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 new Perseverance rover – are serving as pathfinders to eventually get humans to the surface of the Red Planet.

2025年3月24日 · Curiosity used the Mars Hand Lens Imager (MAHLI) camera on the rover’s arm to capture this view of the hole in Cumberland on the same sol as the hole was drilled. The diameter of the hole is about 0.6 inches (1.6 centimeters). The depth of the hole is about 2.6 inches (6.6 centimeters).

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!
