Missions To Mars
This is a list of the 50 spacecraft missions (including unsuccessful ones) relating to the planet Mars, such as orbiters and rovers. Missions ;Mission Type Legend: Mars landing locations There are a number of derelict orbiters around Mars whose location is not known precisely; there is a proposal to search for small moons, dust rings, and old orbiters with the Optical Navigation Camera on the ''Mars Reconnaissance Orbiter''. There should be 8 derelict Mars orbiters barring unforeseen events if they have not decayed as of 2016. One example is Mariner 9, which entered Mars orbit in 1971 and is expected to remain in orbit until approximately 2022, when the spacecraft is projected to enter the Martian atmosphere and either burn up or crash into the planet's surface. The Viking 1 orbiter is predicted not to decay until at least 2019. One orbiter that is confirmed to have undergone Mars atmospheric entry is Mars Climate Orbiter.

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...

Blok D
Blok D (russian: Блок Д meaning Block D) is an upper stage used on Soviet and later Russian expendable launch systems, including the N1, Proton-K and Zenit. The stage (and its derivatives) has been included in more than 320 launched rockets . By 2002 its modification Blok DM had a 97% success rate in 218 flights since 1974, and 43 successful missions in 1997–2002. The stage was developed in 1960s as the fifth stage (' Д' is the fifth letter in the Cyrillic alphabet) for the Soviet Moonshot N1 rocket. The stage first flew in March 1967 while testing Zond of the moonshot program system. During manned lunar flight Blok D would be used for mid-course corrections on the flight to the Moon, then to place the lunar orbiter and lander into a lunar orbit, and decelerate moon-lander out onto its landing trajectory. Blok D was also included as fourth stage of Proton-K and as such flew on unmanned Soviet missions to Moon, Mars (Mars 3) and Venus. It was used in the Proton-K co ...

Titan IIIE
The Titan IIIE or Titan 3E, also known as the Titan III-Centaur, was an American expendable launch system. Launched seven times between 1974 and 1977, it enabled several high-profile NASA missions, including the Voyager program, Voyager and Viking program, Viking planetary probes and the joint West Germany-U.S. Helios (spacecraft), Helios spacecraft. All seven launches were conducted from Cape Canaveral Air Force Station Launch Complex 41 in Cape Canaveral, Florida. Development In the early 1960s, NASA's long-range plan was to continue using Atlas-Centaur until a reusable launch system or a nuclear-powered upper stage could be developed. To help fund the escalating Vietnam War and the new War on Poverty, Congress drastically reduced the funding of the civilian space program. In addition, further development of the reusable launch vehicle was postponed. NASA needed a launch vehicle more powerful than Atlas-Centaur to send heavier planetary probes like Viking and Voyager into spac ...

Viking 1
''Viking 1'' was the first of two spacecraft, along with ''Viking 2'', each consisting of an orbiter and a lander, sent to Mars as part of NASA's Viking program. The lander touched down on Mars on July 20, 1976, the first successful Mars lander in history. ''Viking 1'' operated on Mars for days (over 6 years) or Martian solar days, the longest Mars surface mission until the record was broken by the ''Opportunity'' rover on May 19, 2010. Mission Following launch using a Titan/Centaur launch vehicle on August 20, 1975, and an 11-month cruise to Mars, the orbiter began returning global images of Mars about five days before orbit insertion. The ''Viking 1'' Orbiter was inserted into Mars orbit on June 19, 1976, and trimmed to a 1,513 x 33,000 km, 24.66 h site certification orbit on June 21. Landing on Mars was planned for July 4, 1976, the United States Bicentennial, but imaging of the primary landing site showed it was too rough for a safe landing. The landing was del ...

Mars 7
Mars 7 (), also known as 3MP No.51P was a Soviet Union, Soviet spacecraft launched in 1973 to explore Mars. A 3MP bus spacecraft which comprised the final mission of the Mars programme, it consisted of a Lander (spacecraft), lander and a coast stage with instruments to study Mars as it Flyby (spaceflight), flew past. Due to a malfunction, the lander failed to perform a maneuver necessary to enter the Martian atmosphere, missing the planet and remaining in heliocentric orbit along with the coast stage. Spacecraft Mars 7 spacecraft carried an array of instruments to study Mars. The lander was equipped with a thermometer and barometer to determine the surface conditions, an accelerometer and radio altimeter for descent, and instruments to analyse the surface material including a mass spectrometer. The coast stage, or bus, carried a magnetometer, plasma traps, cosmic ray and micrometeoroid detectors, stereo antennae, and an instrument to study proton and electron fluxes from the Sun ...

Mariner 9
Mariner 9 (Mariner Mars '71 / Mariner-I) was a robotic spacecraft that contributed greatly to the exploration of Mars and was part of the NASA Mariner program. Mariner 9 was launched toward Mars on May 30, 1971 from LC-36B at Cape Canaveral Air Force Station, Florida, and reached the planet on November 14 of the same year, becoming the first spacecraft to orbit another planet – only narrowly beating the Soviet probes ''Mars 2'' (launched May 19) and ''Mars 3'' (launched May 28), which both arrived at Mars only weeks later. After the occurrence of dust storms on the planet for several months following its arrival, the orbiter managed to send back clear pictures of the surface. Mariner 9 successfully returned 7,329 images over the course of its mission, which concluded in October 1972. Objectives Mariner 9 was designed to continue the atmospheric studies begun by Mariner 6 and 7, and to map over 70% of the Martian surface from the lowest altitude () and at the highest reso ...

Mars 3
Mars 3 was a robotic space probe of the Soviet Mars program, launched May 28, 1971, nine days after its twin spacecraft Mars 2. The probes were identical robotic spacecraft launched by Proton-K rockets with a Blok D upper stage, each consisting of an orbiter and an attached lander. After the Mars 2 lander crashed on the Martian surface, the Mars 3 lander became the first spacecraft to attain a soft landing on Mars, on December 2, 1971. It failed 110 seconds after landing, having transmitted only a gray image with no details. The Mars 2 orbiter and Mars 3 orbiter continued to circle Mars and transmit images back to Earth for another eight months. Overview * Launch Date/Time: ** Mars 3: May 28, 1971 at 15:26:30 UTC * Launch mass (including fuel): ** Combined: ** Orbiter: ** Lander: * On-orbit dry mass: * Dimensions: tall, across ( across with solar panels deployed) Orbiter The primary purpose of the 4M-V orbiter was to study the topography of the Martian surface; analyze ...

Mars 2
The Mars 2 was an uncrewed space probe of the Mars program, a series of uncrewed Mars landers and orbiters launched by the Soviet Union beginning 19 May 1971. The Mars 2 and Mars 3 missions consisted of identical spacecraft, each with an orbiter and an attached lander. The orbiter is identical to the Venera 9 bus. The type of bus/orbiter is the 4MV. They were launched by a Proton-K heavy launch vehicle with a Blok D upper stage. The lander of Mars 2 became the first human-made object to reach the surface of Mars, although the landing system failed and the lander was lost.
