Streaks of Flowing Water on Mars
Researchers studying the surface of Mars have noticed thousands of dark streaks appearing on canyon walls and hillsides during Martian summer months. Now they have found definitive evidence of salty liquid water flowing within some of these seasonal streaks. SEPT. 28, 2015

A slope in Horowitz Crater, above, is lined with dark streaks 100 yards long. The streaks are thought to be formed by briny water flowing downhill in warmer months. The bright walls of Garni Crater, below, have similar streaks, which are also known as recurrent slope linae, or R.S.L.s.

A time-lapse animation of Palikir Crater, below, shows how the streaks extend and darken during warmer months on Mars, then gradually fade as temperatures cool.
