Viking Mars lander

American Mars lander. First successful soft landings made at two locations on the Martian surface and returned the first images from the surface. Launched 1975.

The orbiters extensively mapped the surface of the planet. Viking was designed to orbit Mars and to land and operate on the planet's surface. Two identical spacecraft, each consisting of a lander and an orbiter, were built. These spacecraft were launched from Cape Canaveral, Florida in 1975. They spent nearly a year cruising to Mars. Viking 1 reached Mars orbit June 19, 1976, and Viking 2 began orbiting August 7, 1976. Viking 1 landed on Mars July 20, 1976 on the western slope of Chryse Planitia (the Plains of Gold) at 22.3 deg N latitude, 48 deg longitude.

  • Objectives in lunar and planetary exploration for the 1970-1985 - . Nation: USA. Program: Skylab. Spacecraft: Viking.

    National Academy of Sciences report outlining research objectives in lunar and planetary exploration for the 1970s and early 1980s. The Space Science Board of the National Academy of Sciences issued a report outlining research objectives in lunar and planetary exploration for the 1970s and early 1980s. The report affirmed earlier recommendations by the Space Science Board to NASA that unmanned exploration of Mars should have first priority in the post- Apollo space era. Secondary importance was assigned to detailed investigation of the lunar surface and to unmanned Venus probes. Clearly, the report reflected a predominant mood within the scientific community that scientific research in space take predominance over manned programs whose chief objectives, said the report, were 'other than scientific.'

  • Viking Dynamic Simulator - . Payload: VDS. Mass: 3,399 kg (7,493 lb). Nation: USA. Agency: USAF. Spacecraft: Viking.

    The newest addition to the Titan III series, the Titan IIIE/Centaur - a meld of Air Force and NASA technology, suffered a partial failure in its first flight test from Cape Canaveral. The Titan/Centaur vehicle will be used as the launch vehicles for NASA's Viking Mars Lander in 1975 and for the United States-German Helios program.

  • Viking 1 landed on Mars - . Nation: USA. Spacecraft: Viking.

    Viking 1 reached Mars orbit June 19, 1976. Landing was planned for the US Bicentennial on July 4, but was delayed until a suitable landing site was located. The lander separated from the orbiter and touched down on the western slope of Chryse Planitia (the Plains of Gold) at 22.3 deg N latitude, 48 deg longitude.
