For many scientists, however, the euphoria for the complete success of the mission soon turned into a real cold shower. They expected a planet "alive", even with possible traces of vegetation, and instead, the first photos were there to describe a typical lunar landscape, arid and cratered. So, goodbye "Martian civilizations", goodbye to any possibility of finding life evolved in that desert almost without atmosphere ... It was a real disappointment for many. Nor did things improve with the missions that followed. Mars turned out to be a very complex planet, completely different from Earth, but also very different from the Moon. All photos seemed to agree on one fact: the red planet did not look like a place suitable to host higher forms of life. In fact, even if the Mariner probes had categorically excluded the existence of a Martian civilization, there was always the possibility that Mars could still host some form of microbial life. Therefore nothing was lost! The task of clarifying this aspect would have fallen a few years later to the probes Viking 1 and 2... he Viking mission was at that time the most ambitious project undertaken by NASA after the end of the Apollo era. The twin probes Viking 1 and Viking 2, both consisting of an orbiter and a lander, left for Mars on August 20 and September 9, 1975, respectively. After a quiet interplanetary cruise of ten months, Viking 1 entered orbit around Mars on June 19, 1976, and began to take a series of photographs to locate a favorable site for landing, the point was finally identified and on July 20, 1976, the lander separated from the orbiter and after three hours of descent landed on the Martian surface at 11:53 UT. The twin probe entered into orbit on August 7, 1976, and its lander landed on the Martian surface at 22:38 UT on September 3 at a point located about 6500 kilometers from Viking 1. Very soon the first splendid images and a whole series of chemical and physical data of the Martian soil began to arrive on Earth. It was the first time ever that a probe sent back to Earth the appearance of a Martian landscape as it could be seen by a terrestrial explorer. But the absolute novelty of the mission was that both landers had a mechanical arm capable of taking soil samples, and a small internal laboratory capable of performing some simple experiments to highlight the presence of microbial life. Viking, in fact, were not only there to take beautiful pictures, but especially to search for life! Once at NASA they used to do so ... And to this end, the landers performed three types of experiments. The first was the "gas exchange", whereby nutrient broth was added to Martian soil samples, then trying to detect some kind of gaseous emission. Before the addition of nutrients the samples were exposed to water vapor and, to the surprise of scientists, was detected an intense emission of oxygen with traces of nitrogen and carbon dioxide. If the samples were preheated to 145 ° C, a temperature sufficient to kil any terrestrial microbe, the emission of oxygen decreased but did not go to zero. When the nutrient broth was added the scientists detected some gas exchange but the situation remained somewhat confusing. - "If You happen to see any content that is yours, and we didn't give credit in the right manner please let us know at Lorenzovareseaziendale@gmail.com and we will correct it immediately" "Some of our visual content is under an Attribution-ShareAlike license.
