In 1976, NASA sent the Viking 1 mission to Mars, with the aim of investigating the presence of life on the red planet. The mission involved two explorers who conducted ground-breaking experiments. The results at the time seemed to indicate that there was no life. But almost fifty years later, a new theory is raising questions: yes NASAthe technique at the time might have suggested the presence of microbes Mars destruction?
The Vikings conducted various experiments to find organic matter and signs of life. In the end these tests yielded nothing. Astronomer Dirk Schulze-Makuch from the University of Berlin, who has been studying the subject for some time, suggests in an essay in the journal Nature However, NASA made a crucial mistake during these missions: it believed that Martian life – just like on Earth – needs a lot of water. During the experiments, water was mixed with Martian sand, which could be fatal for Martian bacteria, according to Schulze-Makuch.
NASA has long been driven by the discovery of water in its research alien life. However, critics like Schulze-Makuch say that this strategy focuses too much on earthly norms. According to the researcher, life on Mars would survive in very dry conditions, for example by using hygroscopic salts (substances that attract water from the air).
Drowning bacteria as a result of Scandinavian experiments?
In other words, if there are microbes on Mars, they may have really evolved dryness on the red planet. By adding water to soil samples, these organisms could be “drowned,” Schulze-Makuch argues, preventing us from finding them.
Although the hypothesis cannot be tested without new missions, it raises important questions about NASA’s approach. Future missions should focus on organisms that can survive without direct water, according to Schulze-Makuch. Experiments should take into account the specific conditions of Mars, rather than using Earth standards.

Question 1: Can you explain the Viking 1 mission and its objectives for our readers who might not be familiar with it?
Question 2: Based on your expertise, what were the key findings of the Viking 1 mission that concluded there was no life on Mars? Can you comment on the significance of these findings at the time and how they have influenced subsequent research efforts in this field?
Question 3: Would you please elaborate on the new theory proposed by Dr. Dirk Schulze-Makuch regarding the potential mistake made by NASA during the Viking 1 mission? How could water have inadvertently destroyed potential evidence of microbial life on Mars?
Question 4: Given that water is considered a vital component for life as we know it, do you believe that the focus on this aspect might have been a valid approach for NASA in the 1970s? Or do you think there was an inherent limitation to this strategy?
Question 5: If the theory holds true, how could this have impacted our understanding of the possibility of extraterrestrial life and the search for habitable environments beyond Earth?
Question 6: As someone who studies planetary science, what are some of the challenges scientists face when trying to decipher the conditions that could support life on other planets? How can we overcome these challenges to improve our chances of detecting life beyond Earth?
Question 7: With the upcoming Mars 2020 mission and future manned missions to the red planet, what kinds of experiments and technologies do you envision being crucial in addressing the limitations outlined in this debate?
Question 8: As someone with extensive knowledge about the search for extraterrestrial life, what would be your message to policy-makers and scientists about the importance of investing in this field of research?
