In a Martian meteorite that fell in Antarctica, has discovered ancient nitrogen-containing molecules. This means that early Mars existed organic matter.
a Meteorite Allan Hills 84001 was found in 1984. During his recent studies of Japanese planetary scientists saw it as an ancient nitrogen-containing organic molecules. The findings of scientists published in Nature Communications.
Issues, there is or was life on Mars, wondering for decades. But until now, in meteorites from this planet, tried to find of nitrogenous compounds due to technical difficulties, because they are always contaminated by earth organics.
But Mizuho Bed from the Institute of space and Astronautical science of JAXA and her colleagues have developed a new method for such studies. With the help of scientists discovered in the Allan Hills 84001 orange fine-grained formation of carbonate minerals, precipitated from near-surface Martian water about four billion years ago.
a Few grains of such minerals with a size of about 50 micrometers was extracted. They were irradiated with x-rays, the analysis method that helps identify substances by measuring the energy with which they absorb radiation.
it was Found that the samples contain nitrogen, which is part of the organic molecules. Apparently, the organic matter formed on Mars or been brought to it by meteorites from other planets.
researchers came to the conclusion that organic matter, no matter how she got to the “red planet”, has a chance to evolve into more complex forms. Understanding this will help further studies of Martian meteorites and missions, involving taking samples of soil on Mars and its satellites.
