What did Viking 1 and 2 discover?
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 did we learn from Viking 2?
While neither spacecraft found traces of life, they did find all the elements essential to life on Earth: carbon, nitrogen, hydrogen, oxygen and phosphorus.
What did the Viking experiments find?
One experiment, the Labeled Release (LR) experiment, showed that the Martian soil tested positive for metabolism—a sign that, on Earth, would almost certainly suggest the presence of life. However, a related experiment found no trace of organic material, suggesting the absence of life.
What did Viking 1 discover?
About the mission 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.
What was one of the scientific objectives of the Viking program?
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 1 was launched on August 20, 1975 and arrived at Mars on June 19, 1976.
What is the name of the famous photograph from Viking 1?
Face on Mars
The picture, of course, is the famous “Face on Mars” picture, taken by the Viking 1 spacecraft as it made its way to the Red Planet.
What created Valles Marineris?
Most researchers agree that Valles Marineris is a large tectonic “crack” in the Martian crust, forming as the planet cooled, affected by the rising crust in the Tharsis region to the west, and subsequently widened by erosional forces.
What is the Labeled Release experiment?
The labeled release experiment (LR), on the Viking mission, was based on the assumption that any extant life on Mars would metabolize simple carbon compounds and produce gaseous wastes. This experiment produced a great controversy, as its results were inconclusive as to whether or not life existed on Mars.
Can we land a probe on Saturn?
