Was Viking 1 a probe?
On the seventh anniversary of the Apollo 11 lunar landing, the Viking 1 lander, an unmanned U.S. planetary probe, successfully lands on the surface of Mars. Viking 1 was launched on August 20, 1975, and arrived at Mars on June 19, 1976.
Was the Viking I lander A space probe?
The Viking program consisted of a pair of identical American space probes, Viking 1 and Viking 2, which landed on Mars in 1976. The Viking 1 lander touched down on the surface of Mars on July 20, 1976, more than two-weeks before Viking 2’s arrival in orbit.
How long did Viking last on Mars?
Viking Orbiter 1 continued for four years and 1,489 orbits of Mars, concluding its mission August 7, 1980, while Viking Orbiter 2 functioned until July 25, 1978.
What did Viking 1 find on Mars?
While it found no traces of life, Viking 1 did help better characterize Mars as a cold planet with volcanic soil, a thin, dry carbon dioxide atmosphere and strking evidence for ancient river beds and vast flooding.
Is Viking 2 still on Mars?
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. Viking 2 was operational on Mars for 1281 sols (1316 days; 3 years, 221 days)….Viking 2.

What were Viking 1 and 2?
Viking 1 and 2 were a pair of NASA landers and orbiters. Each launched as an integrated spacecraft that separated in Mars orbit. The landers headed for the surface, while the orbiters stayed behind to survey the planet from above.
What did Viking 2 discover?
About the mission While neither spacecraft found traces of life, they did find all the elements essential to life on Earth: carbon, nitrogen, hydrogen, oxygen and phosphorus.
Who invented Viking 1?

Unlike the Earth, Mars and the Moon don’t have strong directional magnetic fields, which means traditional compasses don’t work. Here’s a passage about navigation on Mars where astronaut Mark Watney is trying to get to a landmark several days’ drive away. Navigation is tricky.
Who was the second man on the Moon?
Aldrin set foot on the Moon at 03:15:16 on July 21, 1969 (UTC), nineteen minutes after Armstrong first touched the surface. Armstrong and Aldrin became the first and second people, respectively, to walk on the Moon.
What was the name of the Viking space probe?
The Viking program grew from NASA’s earlier, even more ambitious, Voyager Mars program, which was not related to the successful Voyager deep space probes of the late 1970s. Viking 1 was launched on August 20, 1975, and the second craft, Viking 2, was launched on September 9, 1975, both riding atop Titan IIIE rockets with Centaur upper stages.
When did Viking 1 and 2 land on Mars?
In September 1976, Viking 2— launched only three weeks after Viking 1— entered into orbit around Mars, where it assisted Viking 1 in imaging the surface and also sent down a lander.
What was the mass of the Viking 1 spacecraft?
The scientific payload had a total mass of approximately 91 kg. Following launch and a 304 day cruise to Mars, the orbiter began returning global images of Mars about 5 days before orbit insertion. The Viking 1 spacecraft was inserted into Mars orbit on 19 June 1976 and trimmed to a 1513 x 33,000 km, 24.66 hr site certification orbit on 21 June.
What was the purpose of the Viking mission?
What was Viking 1? 1 Both NASA Viking missions used a combination of orbiter and lander to explore Mars in unprecedented detail. 2 In total, the two Viking orbiters returned 52,663 images of Mars and mapped about 97 percent of the surface at a… More
