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. [2] The lander touched down on Mars on July 20, 1976, the first successful Mars lander in history.

2024年11月2日 · Viking 1 was the first of a pair of complex deep space probes that were designed to reach Mars and to collect evidence on the possibility on life on Mars. Each spacecraft was composed of two primary elements, an orbiter (5,157 pounds or 2,339 kilograms) and a lander (2,156 pounds or 978 kilograms).

1975年8月20日 · The first spacecraft to successfully land on Mars, Viking 1 was part of a two-part mission to investigate the Red Planet and search for signs of life. Viking 1 consisted of both an orbiter and a lander designed to take high-resolution …

2024年11月4日 · Viking 1 launched aboard a Titan IIIE rocket August 20, 1975 and arrived at Mars on June 19, 1976. The first month was spent in orbit around the Martian planet and on July 20, 1976 Viking Lander 1 separated from the Orbiter and touched down at Chryse Planitia.

2021年7月20日 · The Viking 1 lander held the record for the longest operating spacecraft on the surface of Mars, 2307 Earth days (more than six years) or 2245 Martian sols, until May 19, 2010, when the Opportunity rover surpassed it.

2024年11月6日 · Viking 1. The first spacecraft to successfully land on Mars, Viking 1 was part of a two-part mission to investigate the Red Planet and search for signs of life. Viking 1 consisted of both an orbiter and a lander designed to take high-resolution images and study the Martian surface and atmosphere.

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.

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.

Viking Lander 1 made its final transmission to Earth Nov. 11, 1982. Besides taking digital images and collecting other science data on the Martian surface, the two landers conducted three biology experiments designed to look for possible signs of life.

Forty years ago today (July 20), NASA's Viking 1 Mars lander became the first American spacecraft to touch down safely on the Red Planet.
