In 1976, Dual NASA VIKING LANDERS completely stopped on the red planet.
The results of their life detection experiments still argue with continuous discussions about repercussions in the scientific community: Is there a life for Mars?
Today, the new paper tackles and reconsiders the results of the Viking Biology Experiment.
Discovery of hydrogenomyitis
The most important change in the 1970s was to find high levels of hydrochloride in Mars. Overwriting hydrochloride and non -biological oxidants explain the Vikings and do not need to assume harmony life.
“Phoenix Mission found that the discovery of hydrochloride in Mars provided the foundation for explaining the results of the Viking Randers.” [Viking] The device can explain the lack of detected organic matter. The accumulation of chlorine acid salt from the space ray decomposition of hydrochloride can explain the reactivity seen when the nutrient solution is added to the soil in the viking biology experiment. “
But the paper added, “The non -biological explanation of the Viking outcome does not exclude Mars’ life.”
Visit the results again
The Viking Biology Experiment of the Mars Revisited ”was written by Hwaseong Researcher Christopher McKay, Richard Quinn, and Carol Stoker, all three authors in Morpetfield, California, near San Francisco, NASA’s ames in California, California. I am from the space science department of the Research Center.
The team suggested that “the Mars sample is returned to the horizon, and the future mission may be timely visiting the results of the Viking biology experiments, including the prospect of Mars and perhaps life detection tools.” “Vikings have changed a lot since landing on Mars and many have not changed. What has not changed in the last 50 years is our understanding of the limits of cold and dry environment.”
He said in communication with Christopher MCKAY Space.com: “It is important not to say that the viking results are not to say that there is no life for Mars. The viking results do not mean that there is life on Mars.”
MCKAY said that their core point is that the Viking results have hydrochloride and other oxidizers on Mars.
This is that the results of the Viking biology test cannot be used to justify the approach to the astronaut health and safety or samples and/or astronauts.
New data
In a paper for scientific journals Icarus Research Trio explains that there is a big change from mission to Mars. “The most important new data so far was an amazing discovery of Phoenix mission containing about 0.5% hydrolitis in Mars soil.” “This huge concentration of hydrotherapy is still not properly explained, but the impact on the Viking outcome is deep.”
Space scientists in their papers explain that the conclusion that the hydrochloride model and the Vikings did not detect life in the surface soil of Mars will consider the return of the sample of Mars or the discussion of astronauts.
“External space treaties prohibit the adverse change in the global environment due to the introduction of alien substances.” McKay and colleagues added.
Good goal
When summarizing the research paper, they concluded that the hydrochloride model for the Viking outcome does not prove that there is no life in Mars, and that it does not suggest that the continuous search for evidence of life in the past or present Mars is meaningless.
In fact, as the team suggested, “We strongly insist on finding evidence of life in the future. A good goal is salt sediment and polar stone ice.”
