Mars meteorite analysis for signs of life: here’s what scientists found

Regarding Mars, the biggest question before scientists is whether there was ever life on the Red Planet? While the search for life on Mars continues, and with more enthusiasm than ever, conclusive results are unlikely to be found anytime soon. NASA aims to bring back samples of Mars by 2030 and only analyzing them will make it clear whether life exists on the planet. However, scientists are studying material obtained from Mars – in the form of meteorites. Researchers from Lund University in Sweden examined a 1.3-billion-year-old meteorite from Mars and found that it was limited in contact with water. In other words, life was unlikely to exist at that specific time and place.

Scientists use neutron and X-ray tomography, the same techniques that will be used to study the samples they are collecting. persistence rover and will be brought back from Mars planet, to arrive at their conclusions. They used the technology to understand if there were any major hydrothermal systems, which are generally conducive to life. X-ray tomography is a common method of studying an object without damaging it. Neutron tomography was used because neutrons are sensitive to hydrogen.

Hydrogen has always been of interest in finding traces of life on another planet because water (H2O) is a prerequisite for life as we know it. Josephine Martel, a geology doctoral student at Lund University, said, “Since water is central to the question of whether life ever existed on Mars, we wanted to investigate how the meteorite reacted with water when it was still near Mars. Was part of the base.” one in Statement,

The findings suggest that a fairly small portion of the meteorite reacted with water. This means that the sample of Mars’ crust “could not provide a habitable environment that could harbor any life”. Mars planet“During that specific period, the scientists write in the study published in the journal” science advance,

they hope their findings will help NASA Scientists study samples when they are brought back to Earth.
