Drilling by Curiosity Mars rover at a region of the Red Earth Known as the”clay-bearing unit” has revealed the highest Quantities of clay minerals ever found during the mission, NASA has Stated.
The rover recently drilled two samples at rock targets called”Aberlady” and”Kilmarie”, the US space agency revealed on Wednesday.
Clay frequently forms in water, which is vital for life. Other than proof that there was a significant amount of water what these findings mean for the region remains up for debate.
It is likely that the stones in the area formed as layers of sand in ancient lakes – some thing Curiosity also found lower on Mount Sharp mountain on Mars.
Water interacted with sediment over time, leaving an abundance of clay from the stones there, NASA said.
This clay-enriched region is on the side of reduced Mount Sharp.
The rover’s mineralogy instrument, called CheMin (Chemistry and Mineralogy), provided the first analyses of rock samples drilled from the clay-bearing unit, NASA said.
