Some of you may not know, but Martians are still arguing what is called the Wet versus Dry Debate. And recently, some more light has been shed on the matter...
The Wet versus Dry debate relates to, well, is Mars actively and currently wet or completely dry? What spurred this debate? It's always been a debate with geologic markers pointing to previous glacial activity and the like....but recently?
Well, let us talk about Recurring Slope Lineae. These are warm seasonal flows that are found in specific areas on Mars. And we still have no clue what generates them. Not to be confused with slope streaks, these annual streaks are smaller and pop out every Martian spring/summer season.
These little streaks have been making a HUGE deal in the Martian Wet versus Dry debate!
If they were wet- why don't we see them all over Mars during the changing seasons?
If they were dry- why don't we see them all over dunes and more dusty areas?
November 2017, a group from Arizona published a small paper bringing up the Dry side of the debate, and thus the debate re-sparked interest!
Could it be granular flows? Could something under the surface be causing a push of material?
Hopefully, we will find out soon enough!
Thank you for reading and come back next week for a look at frosted dunes!
