RSLs on Mars!
Happy Monday, Earthlings!
We are back! Going to start back by talking about what in the world are RSLs!
Recurring Slope Lineae are thin, wet-looking materials slumping out of the walls of craters on Mars. But these little guys are tricky- we don't have a definite answer for how these are formed, what material, or why they are rare!
So this is what we hypothesized:
1- they are seasonal, which means they grow and extend a couple meters in the Spring and fade in the Winter.
2-it is briny (very salty) water, but the movement processes are still yet to be understood
3-most features usually darken as the water evaporates, leaving behind the salt, but some features brighten. Reasons are still unknown.
4-Lab experiments are still being used to figure out how RSLs seep out of crater walls and flow down a slope!
Thank you for reading and come back next week for an overview of the Mars 2020 rover!
