In contrast to recurring slope lineae (RSL) and dark dune spots (DDS) that appear and disappear annually following the seasonal cycle, slope streaks can form in any season and take tens of years to dissolve.
In this research we analyze all the possible explanations proposed, crossing all the available information to analyze both slope streaks and RSL and DDS.
Temperature, pressure, relative air humidity, soil moisture and thermal inertia are used as reference points to analyze both “dry” explanations and those involving the presence of liquid water.
Does a hydrological cycle still exist on Mars?
It would seem so…
