The Viking 2 mission was part of the American Viking program to Mars, and consisted of an orbiter and a lander essentially identical to that of the Viking 1 mission. [1] Viking 2 was operational on Mars for 1281 sols (1,316 days ; 3 years, 221 days ).

2024年11月2日 · What was Viking 2? Both NASA Viking missions used a combination of orbiter and lander to explore Mars in unprecedented detail. Viking 2 entered orbit around Mars on Aug. 7, 1976. The lander touched down safely on Sept. 3, 1976, about 4,000 miles (6,460 kilometers) from the Viking 1.

1975年9月9日 · Viking 2 landed on Mars in September 1976 -- immediately following the first successful spacecraft landing on Mars by Viking 1 -- and was part of NASA's early two-part mission to investigate the Red Planet and search for signs of life.

2024年11月6日 · Viking 2 landed on Mars at Utopia Planitia (47.64° N, 134.29° E, planetocentric) on Sept. 3, 1976 -- immediately following the first successful spacecraft landing on Mars by Viking 1 -- and was part of NASA's early two-part mission to …

NASA's Viking Mission to Mars was composed of two spacecraft, Viking 1 and Viking 2, each consisting of an orbiter and a lander. The primary mission objectives were to obtain high resolution images of the Martian surface, characterize the structure and composition of the atmosphere and surface, and search for evidence of life.

The Viking 1 lander touched down on the western slope of Chryse Planitia (the Plains of Gold), while the Viking 2 lander settled down at Utopia Planitia. The last data from Viking Lander 2 arrived at Earth on April 11, 1980. Viking Lander 1 made its final transmission to Earth Nov. 11, 1982. Relevance to Astrobiology

Viking 1 and 2 were a pair of NASA Mars landers and orbiters that launched in 1975 and arrived in 1976. The orbiters created global maps while the landers examined the surface up close. The landers performed ambitious chemistry experiments to search for life; the results were ambiguous.

2020年8月20日 · Viking 2 entered orbit around Mars on July 25 and the lander made its touchdown in Utopia Planitia on Sept. 3. Launches of the Viking spacecraft: Viking 1, left, and Viking 2. Both orbiters and landers far exceeded their expected 90-day lifetimes in their scientific exploration of Mars, vastly increasing our knowledge of the planet, its ...

2024年11月4日 · NASA's Viking Mission to Mars was composed of two spacecraft, Viking 1 and Viking 2, each consisting of an orbiter and a lander - orbiters for imaging and scientific operations from orbit, and landers deployed instruments on the surface.

海盗2号（viking 2）的目标是探测火星大气结构及组成以及寻找是否有生命的迹象。 包含海盗2号（VIKING 2）轨道太空船以及无人登陆艇，自卡纳维尔角以泰坦（TITAN 3E）运载火箭发射升空，其主要任务与海盗1号相同，均为取得高清晰度的火星地表照片，并探测火星 ...
