Scientists confirm there’s water in the dark streaks on Mars

by Laura Domela

Scientists have caught Mars crying salty tears.

Photos from NASA’s Mars Reconnaissance Orbiter show dark streaks flowing down Martian slopes. The streaks appear in sunny spots or when the weather is warm, and they fade when the temperature drops.
