Imagine that you took a picture because it has to be deleted because of its capacity, it was discovered a long time ago, No, the people in the photo were aliens, Looking for clues for you. What is annoying is that what NASA did in 1976 may not be the same thing.
Some time ago, NASA announced that the Curiosity rover had found organic matter for the first time on Mars and that everyone knows that this honor could be awarded to Mars to detect the ancestor Viking instead of Curiosity. . A new report published in the journal Geophysical Research suggests that more than 40 years ago, when the Viking lander explored the surface of Mars, he could have found organic matter, but inadvertently burned evidence of $ 5 billion.
The Viking 1 and Viking 2 ships were part of NASA's Viking project, with both landers landing on Mars in 1976, opening the first Mars surface survey mission targeting Martian soil. Organic Compounds
To the surprise of all, this search has no results. Chris McKay, a NASA astrobiologist, said that when scientists badume that meteorites and carbon-containing comets would reach the surface of Mars, they should deposit organic matter on the surface of Mars. Completely incoherent, since then scientists have come up with another theory that the meteoritic impact actually destroys organic molecules.
But the criminal who destroys the organic matter of Mars is really only a meteorite? No, according to a new study by Chris McKay, scientists have discovered that it may have been the opposite of the instrument itself.
First, the Viking LG carries the gas chromatograph-mbad spectrometer (GC-MS), the main instrument used to detect Martian soil life, it must be heated to badyze the samples of Mars; In 2008, NASA Phoenix Lander discovered the toxic compound Martian soil perchlorate, a toxic component commonly found in rocket fuel, pyrotechnics and emergency lighting signals that would explode at high temperatures.
So what happens when the Viking Lander warms up a sample of Mars and encounters perchlorate? Hey! Of course, it is immediately burned with any organic matter that may be present. In fact, Curiosity discovered Mars chlorobenzene molecules in 2013, which is the chemical of burning carbon perchlorate.
When the researchers came back and rebadyzed the old data from the Viking, they were surprised to find that the Viking had detected chlorobenzene at the time – a possible explanation for this data was that the own instruments of the NASA burned them. Spend up to $ 5 billion to find evidence of organic molecules.
Of course, we do not know if the Viking really did that, the research is only an explanation for the data, and other scientists involved in the research have done some research. other ideas, such as Melissa Guzman from LATMOS Research Center in France. There is not enough evidence to prove that the Viking lander burned organic matter on Mars, and that these chlorobenzene molecules may also be contaminated by the Earth.
In short, this tells us that even the world's greatest scientists of space, the most expensive and advanced instruments, may not be able to achieve 100% perfection .
