Viking 1	Permalink

Following launch using a Titan/Centaur launch vehicle on August 20, 1975 and a 10-month cruise to Mars, the orbiter began returning global images of Mars about 5 days before orbit insertion. The Viking 1 Orbiter was inserted into Mars orbit on June 19, 1976 and trimmed to a 1513 x 33,000 km, 24.66 h site certification orbit on June 21. Read more __________________

Viking Lander 1	Permalink

Viking 1 was the first of two spacecraft sent to Mars as part of NASA's Viking program. The Viking 1 Orbiter was inserted into Mars orbit on June 19, 1976 and trimmed to a 1513 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 delayed until a safer site was found. The lander separated from the orbiter on July 20 08:51 UT and landed at 11:53:06 UT. It was the first attempt by the United States at landing on Mars. Read more __________________

Missing Piece Inspires New Look at Mars Puzzle Experiments prompted by a 2008 surprise from NASA's Phoenix Mars Lander suggest that soil examined by NASA's Viking Mars landers in 1976 may have contained carbon-based chemical building blocks of life. Read more __________________

Anniversary of Viking 1, Mars Landing. (1976) Viking 1 was the first of two spacecraft sent to Mars as part of NASA's Viking program. It was the first spacecraft to successfully land on Mars and perform its mission, and holds the record for the second longest Mars surface mission of 6 years and 116 days (from landing until surface mission termination, Earth time).

Viking Lander 2	Permalink

The ice exposed by fresh impacts suggests that NASA's Viking Lander 2, digging into mid-latitude Mars in 1976, might have struck ice if it had dug only 10 centimetres deeper. The Viking 2 mission, which consisted of an orbiter and a lander, launched in September 1975 and became one of the first two space probes to land successfully on the Martian surface. The Viking 1 and 2 landers characterised the structure and composition of the atmosphere and surface. They also conducted on-the-spot biological tests for life on another planet.
