A research study team led by Lund University in Sweden has actually investigated a meteorite from Mars using neutron and X-ray tomography. The technology, which will likely be used when NASA analyzes samples from the Red Planet in 2030, showed that the meteorite had actually restricted direct exposure to water, therefore making life at that specific time and place not likely.
It isnt until around 2030 that NASA actually plans to send the samples back to Earth, however material from Mars is already being studied– in the type of meteorites. In a new study released in the journal Science Advances on May 11, 2022, an international research study team has studied a roughly 1.3 billion-year-old meteorite utilizing advanced scanning.
” Since water is main to the concern of whether life ever existed on Mars, we wished to examine how much of the meteorite reacted with water when it was still part of the Mars bedrock,” explains Josefin Martell, geology doctoral student at Lund University.

To respond to the question of whether there was any major hydrothermal system, which is usually a beneficial environment for life to happen, the researchers utilized neutron and X-ray tomography. X-ray tomography is a typical technique of examining an object without harming it. Neutron tomography was utilized since neutrons are very sensitive to hydrogen.
This indicates that if a mineral includes hydrogen, it is possible to study it in three measurements and see where in the meteorite the hydrogen lies. Hydrogen (H) is constantly of interest when scientists research study product from Mars, due to the fact that water (H2O) is a prerequisite for life as we understand it. The outcomes show that a relatively small part of the sample seems to have actually reacted with water, and that it therefore probably wasnt a big hydrothermal system that gave rise to the alteration.
” A more probable description is that the response occurred after small accumulations of underground ice melted throughout a meteorite effect about 630 million years back. Obviously, that doesnt suggest that life couldnt have actually existed in other places on Mars, or that there couldnt have actually been life at other times,” states Josefin Martell.
The scientists hope that the results of their study will be helpful when NASA revives the very first samples from Mars around 2030, and there are numerous factors to think that the current technology with neutron and X-ray tomography will work when this occurs.
” It would be enjoyable if we had the chance to study these samples at the research center European Spallation Source, ESS in Lund, which by then will be the worlds most effective neutron source,” concludes Josefin Martell.
