Did NASA Accidentally Wipe Out Martian Life in the 1970s?
A German astrobiologist is raising eyebrows with a controversial new theory about life on Mars and its potential demise. Dirk Schulze-Makuch, from Technische Universität Berlin, suggests NASA’s Viking 1 mission might have inadvertently killed Martian organisms during its 1976 experiments.
"In an environment that is too dry, life can get ‘water’ from salt that captures moisture from the atmosphere. This salt should be at the heart of the search for living things on Mars," Schulze-Makuch said.
Schulze-Makuch argues that life on Mars could be salt-dependent, similar to certain microbes found in the Atacama Desert’s dry conditions. He points to the Viking 1 mission’s exploration, where researchers mixed water, nutrients, and Martian soil samples, assuming Martian life would need water to survive, just like on Earth.
He believes the Viking 1 mission’s experiments, designed to detect signs of life, may have inadvertently flooded these potential Martian organisms, leading to their death. "If this view of how organisms survive in the dry conditions of Mars is correct, this means that instead of using the ‘search for water’ strategy that NASA has been practicing, we would be better off following the salt to find microbes," Schulze-Makuch explains.
He proposes a new approach, advocating for using a salt-based solution as a habitat for transporting Martian microorganisms back to Earth. He uses the example of a rainstorm devastating a large percentage of bacteria in the Atacama Desert due to excessive water exposure in a short period.
Schulze-Makuch concludes by stating,
“Almost 50 years after the Viking biology experiments, it is time to try a new life search mission, with a better understanding of the Martian ecosystem."
Could this theory rewrite our understanding of Martian life and NASA’s past missions? Neural networks have shown promise in visualizing biological structures potentially present in Mars’s unique landscape. If Schulze-Makuch is right, will NASA adjust its approach in future Mars explorations?

## Did NASA Accidentally Kill Martian Life in the 1970s? An Expert Interview
**World-today-News.com** spoke with Dr. Lena Kepler,a renowned astrobiologist and former NASA researcher,about the controversial theory proposed by Dirk Schulze-Makuch regarding the potential demise of Martian life during the Viking 1 mission.
**WTN:** dr. Kepler, Dr. Schulze-Makuch postulates that life on Mars might be salt-dependent and that NASA’s Viking 1 mission inadvertently killed martian organisms by introducing water into the Martian soil samples. What are your initial thoughts on this theory?
**Dr. Kepler:** Dr. Schulze-Makuch raises intriguing points. The possibility of extremophiles adapted to Mars’ harsh, arid environment is certainly plausible. We certainly know life on Earth thrives in incredibly diverse and seemingly inhospitable environments, from the depths of the ocean to the driest deserts. Extrapolating that to Mars,salt-dependent lifeforms adapted to utilize atmospheric moisture,as seen in the Atacama Desert,is an engaging hypothesis.
**WTN:** The Viking 1 experiments were designed assuming life on Mars would need liquid water for survival, similar to Earth life. Was this a flawed assumption, as Dr. Schulze-Makuch suggests?
**Dr. Kepler:** Hindsight is always 20/20. While the Viking missions were groundbreaking and provided invaluable data about Mars’ environment, our understanding of extremophiles has evolved substantially since then. It’s possible that our initial assumptions about Martian life – being carbon-based and requiring liquid water - were too narrow.
**WTN:** Dr. Schulze-Makuch suggests that the Viking 1 experiments, by introducing water, inadvertently created a hostile environment for any potential salt-dependent Martian life. Is this a feasible scenario?
**Dr. Kepler:** It’s certainly conceivable. Introducing a substantial amount of water into a system where life has adapted to exist with minimal moisture could have been detrimental. It’s akin to flooding a desert ecosystem – the immediate impact could be disruptive and potentially fatal to organisms adapted to that specific environment.
**WTN:** What implications might this have for future Mars exploration and the search for extraterrestrial life?
**Dr. Kepler:** The potential implications are notable. It necessitates a re-evaluation of our experimental methodologies for investigating Martian life. We need to consider the possibility of extremophiles with unique metabolic pathways and adapt our experiments accordingly. For example, instead of immediately introducing water, we should consider studying Martian soil samples in their natural, dehydrated state first. Analyzing the composition of the Martian soil,especially the presence and types of salts,will be crucial in understanding the potential for salt-dependent life.
**WTN:** Dr. Kepler, thank you for sharing your insights. What message do you have for the public regarding this challenging and engaging topic?
**dr. Kepler:** The search for life beyond Earth is a complex and multifaceted endeavor. while we haven’t found definitive proof of martian life yet,the possibility remains tantalizing. This latest theory highlights the importance of continuous scientific inquiry, adapting our methods as we gain new knowledge, and remaining open to the possibility of life as we don’t yet know it.
