SAN FRANCISCO — The intriguing story of Mars’ mysterious dark streaks may have a new twist.

The streaks, known as recurring slope lineae (RSL), occur seasonally on steep, relatively warm slopes at many locations on the Red Planet. They were discovered in 2011 by scientists studying images captured by NASA’s Mars Reconnaissance Orbiter (MRO).

Many researchers initially speculated that RSL may be signs of liquid water at or near the Martian surface, and this hypothesis got a big boost last year when a study reported that MRO had detected hydrated salts within the streaks.

Congratulations :)

BASTARD!

Gough and her colleague, Margaret Tolbert, also of UC Boulder, performed lab experiments to test this idea. They exposed various anhydrous (dry) salts to Mars-like atmospheric conditions and found that some of them — calcium perchlorate and calcium chloride — did indeed become hydrated. (The RSL salts on Mars appear to be perchlorates of some kind, the researchers who spotted them wrote in their 2015 study.)

so they become hydrated when in contact with the atmosphere

can it be both possibilities?
