The team detected crucial saline sediment that appears to have formed when water passed through the rock sampled. The salt is expected to have trapped some of the ancient water of Mars in its pockets, confirming that there could be signs of life preserved. Although there have only been two samples of this rock, it will take much longer for scientists to learn more about the makeup of Mars and the extent to which life could flourish on the planet. The samples will not return to Earth until future missions collect the samples and perseverance is left behind.
The early data bodes well for NASA’s current Perseverance mission, as it provides a lot of useful information about the structural history of Mars, pointing scientists in the right direction for future research on Mars.
