The scientists used neutron and X-ray tomography. This is the same technology that will be used to study the samples brought by the Perseverance rover. This technique was used because scientists wanted to find out if there had ever been a large hydrothermal system that would have been suitable for life to flourish. X-ray tomography is a common method of studying an object without damaging it. Neutron tomography was used because neutrons are very sensitive to hydrogen.
Scientists hope to find hydrogen first to find life because we know that water is the first requirement for life. “We wanted to investigate how the meteorite might have reacted with water when it was part of the Martian rock,” said a geology doctoral student at Lund University.
The research found that only a small part of the meteorite may have reacted with the water. This means that the samples found on the surface of Mars did not contain anything that harbored life at that time. This study of scientists has also been published in the journal Science Advances. Scientists hope that their discovery will also be helpful for NASA scientists when they return to Earth with samples from Mars.
