What was the Viking 2 mission?
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. The Viking 2 lander operated on the surface for 1316 days, or 1281 sols, and was turned off on April 12, 1980, when its batteries failed.
What did Viking 1 and 2 discover?
These experiments discovered unexpected and enigmatic chemical activity in the Martian soil, but provided no clear evidence for the presence of living microorganisms in soil near the landing sites. According to scientists, Mars is self-sterilizing. The Viking mission was planned to continue for 90 days after landing.
What was the mission of Viking landers?
About the mission 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.
What is the Mars Odyssey mission?
NASA’s Mars Odyssey holds the record for the longest continually active spacecraft in orbit around a planet other than Earth. The spacecraft’s main mission is to investigate the Martian environment and to provide key information on hazards future explorers might face.
When was Viking 1 and 2 released?
On July 20, 1976 the Viking 1 Lander separated from the Orbiter and touched down at Chryse Planitia (22.27° N, 312.05° E, planetocentric). Viking 2 was launched September 9, 1975 and entered Mars orbit on August 7, 1976.
Who designed the Viking 2?

What did Voyager 1 discover?
Voyager 1 is the first human-made object to venture into interstellar space. Voyager 1 discovered a thin ring around Jupiter and two new Jovian moons: Thebe and Metis. At Saturn, Voyager 1 found five new moons and a new ring called the G-ring.

What were the results of the life sciences experiments aboard the Viking landers?
(Phys.org)—In 1976, two Viking landers became the first US spacecraft from Earth to touch down on Mars. In the forty years since these experiments, scientists have been unable to reconcile the conflicting results, and the general consensus is that the Viking landers found no conclusive evidence of life on Mars.
What type of spacecraft is Mars Odyssey?
robotic spacecraft
2001 Mars Odyssey is a robotic spacecraft orbiting the planet Mars. The project was developed by NASA, and contracted out to Lockheed Martin, with an expected cost for the entire mission of US$297 million.
What is the Odyssey orbiter?
The Odyssey orbiter is a communications relay for rovers and landers on Mars including the Mars Exploration Rovers “Spirit” and “Opportunity,” the Mars Phoenix lander and the Mars Science Laboratory’s Curiosity rover.
What was the purpose of the Viking 1 mission?
About the mission 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.
What did the Viking 2 mission find on Mars?
While neither spacecraft found traces of life, they did find all the elements essential to life on Earth: carbon, nitrogen, hydrogen, oxygen and phosphorus. Like its predecessor, the Viking 2 mission consisted of a lander and an orbiter designed to take high-resolution images, and study the Martian surface and atmosphere.
What was the cost of the Viking 2 mission?
Viking 2 then successfully soft-landed on September 3. The orbiters continued imaging and performing other scientific operations from orbit while the landers deployed instruments on the surface. The project cost was roughly $1 billion at the time of launch, equivalent to about 5 billion USD in 2019 dollars.
What was the purpose of the Viking Orbiters?
Viking orbiters. The primary objectives of the two Viking orbiters were to transport the landers to Mars, perform reconnaissance to locate and certify landing sites, act as communications relays for the landers, and to perform their own scientific investigations.
