about 11 million years ago. Previous research has suggested that nakhlites might shed light on the Red Planet's ancient hydrothermal systems, and particularly its hot springs. Hot springs are an intriguing target because scientists think these environments may have been cradles for early life onIn the new study, researchers examined the Miller Range 03346 nakhlite, a 1.58-pound rock that scientists discovered in the Miller Range of mountains in Antarctica in 2003.
"From previous research, we know that minerals in this specific meteorite reacted with water about 630 million years ago," study lead author Josefin Martell, a planetary scientist at Lund University in Sweden, told Space.com.But Martell and her colleagues wanted more detail about the rock's history.
"I think it's really exciting that we can study meteorites without having to cut them open," Martell said."We scanned our samples using X-rays and neutrons, and basically got a 3D image showing what our sample looked like on the inside." The scientists found that minerals within the meteorite that liquid water had altered were concentrated within isolated patches. This pattern suggests that the water responsible for altering these minerals did not leak into the rock from a hydrothermal system. Instead, the researchers argued that the water likely came from ice buried within the rock itself that melted during the impact that blasted the nakhlite off Mars.
