The planet Mars has been explored remotely by spacecraft. Mariner 6 and 7 were the second pair of Mars missions in NASA's Mariner series of solar system exploration in the 1960s and early 1970s. Jay Friedlander, …

Mariner 9 and the Vikings went into orbit around the planet and the Vikings placed two landing craft on the surface of Mars. Mariner 4 studies Martian surface The unmanned spacecraft Mariner 4 passes over Mars at an altitude of 6,000 feet and sends back to Earth the first close-up images of the red planet. Mariner 4 was the fourth series of spacecraft that was used for planetary exploration as a flyby mode.

It was designed as a technology demonstration of a new way to deliver an instrumented lander and the first-ever robotic rover to the surface of the red planet. Mariner 4 images . Detailed Information on the Spacecraft, Experiments, and Data Sets. When Mariner 9 reached Mars in 1971, it and two Soviet orbiters (Mars 2 and Mars 3, see Mars probe program above) found that a planet-wide dust storm was in progress. Mariner 3 is now in a solar orbit. Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. Mariner 4 was the first spacecraft to obtain and transmit close range images of Mars. The spacecraft launched on Nov. 28, 1964, and was the first to fly by Mars on July 14, 1965. Mariner 5 ABOUT THE MISSION One of the great successes of the early American space program, the Mariner 4 mission journeyed to Mars -- making its closest approach on July 15, 1965 -- and took the first photos of another planet from space. Mariner-H (Mariner Mars '71), also commonly known as Mariner 8, was (along with Mariner 9) part of the Mariner Mars '71 project.It was intended to go into Mars orbit and return images and data, but a launch vehicle failure prevented Mariner 8 from achieving Earth orbit and the spacecraft reentered into the Atlantic Ocean shortly after launch. Introduction. Two days after Mariner 4 launched, the Soviet Union tried again with Zond 2. Pathfinder not only accomplished this goal but also returned an unprecedented amount of data and outlived its primary design life. Mariner 6 & 7 Four years later, NASA readied two identical spacecraft, Mariners 6 and 7, which would further study Mars by flying … Target Object: Mars Mission: Mariner 4 Heavily cratered area in western Memnonia Fossae on Mars Target Object: Mars Mission: Mariner 4 (Page 1 of 3) Read about the Mariner 4 Mission | HOME | MISSION INDEX | FAQ | Authors/Curators: Dave Williams,, (301) 286-1258 Code 690.1, NASA Goddard Space Flight Center Greenbelt, MD 20771, USA.

Decades before Spirit and Opportunity were launched, a probe named Mariner 4 lifted off from Cape Canaveral, Fla. On July 14, 1965, it reached the planet Mars and took the first photos humans had ever seen of another world: 21 grainy black and white images, sent back through the distances of space. Mars Pathfinder was launched December 4, 1996 and landed on Mars' Ares Vallis on July 4, 1997.
