Two countries have successfully deployed rovers on Mars, the United States first doing so with Sojourner in 1997 and China with Zhurong in 2021. NASA's Viking 1 lander transmitted the first images from the Martian surface in 1976. Mariner 4 detected the weak Martian radiation belt, measured at about 0.1% that of Earth, and captured the first images of another planet from deep space.

Mariner 4 was the first spacecraft to visit Mars launched by NASA on 28 November 1964, it made its closest approach to the planet on 15 July 1965. Mars has been explored by several uncrewed spacecraft. The days and seasons on Mars are comparable to those of Earth as the planets have a similar rotation period and tilt of the rotational axis relative to the ecliptic plane. Mars has two small and irregularly shaped moons, Phobos and Deimos. The smooth Borealis basin in the Northern Hemisphere covers 40% of the planet and may be a giant impact feature. Olympus Mons, the largest volcano and highest known mountain on any Solar System planet, and Valles Marineris, one of the largest canyons in the Solar System, are on Mars. Mars is a terrestrial planet with a thin atmosphere, with surface features such as impact craters, valleys, dunes, and polar ice caps.

The latter refers to the effect of the iron oxide prevalent on Mars's surface, which gives it a striking reddish appearance in the sky. In English, Mars carries the name of the Roman god of war and is often called the ' Red Planet'. Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury.
