The following outline is provided as an overview of and topical guide to Mars: Mars – fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" [1] [2] because the iron oxide prevalent on its surface gives it a reddish appearance.
It was not until spacecraft visited the planet during NASA's Mariner missions in the 1960s that these myths were dispelled. Some maps of Mars were made using the data from these missions, but it wasn't until the Mars Global Surveyor mission, launched in 1996 and ending in late 2006, that complete, extremely detailed maps were obtained.
NASA's Mariner 4 was the first spacecraft to visit Mars; launched on 28 November 1964, it made its closest approach to the planet on 15 July 1965. 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.
The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars. "Hottah" rock outcrop on Mars – ancient streambed [1] [2] [3] viewed by the Curiosity Rover (September 12, 2012, white balanced) (raw, close-up, 3-D version). Abundant iron compounds are responsible for the bright brownish-red ...
Artist's rendition of Mars Express as seen by NASA's Mars Global Surveyor Image of Mars Express in orbit at Mars. 2001 Mars Odyssey was launched April 7, 2001 on a Delta II rocket and currently holds the record for the longest-surviving continually active spacecraft in orbit around a planet other than Earth at 23 years, 3 months and 28 days.

Landsat 9 is an Earth observation satellite launched on 27 September 2021 from Space Launch Complex-3E at Vandenberg Space Force Base on an Atlas V 401 launch vehicle. [12] NASA is in charge of building, launching, and testing the satellite, while the United States Geological Survey (USGS) operates the satellite, and manages and distributes the data archive. [13]
Engineers from NASA’s Jet Propulsion Laboratory in Southern California and AeroVironment are completing a detailed assessment of the Ingenuity Mars Helicopter’s final flight on January 18, 2024, the first of its kind on an extraterrestrial planet, concluding that the inability of Ingenuity’s navigation system to provide accurate data ...
2023 FW 14 is a small asteroid orbiting near the L 4 point of Mars (60 degrees ahead of Mars on its orbit). As of March 2024, it is the second known asteroid to orbit the leading L 4 point of Mars together with (121514) 1999 UJ 7, although at least 15 other asteroids orbit Mars's trailing L 5 point, including 5261 Eureka, (101429) 1998 VF 31, and 2007 NS 2.
