A new analysis of Martian surface images finds evidence of persistent, strong runoff from Martian rivers even as the planet's atmosphere was becoming less hospitable to water.

Scientists have detected an underground reservoir of liquid that may be saltwater under Mars' southern polar ice cap.

Researchers have identified new surface features that appear on Mars’ slopes during the warm season and fade in the cold season. These clusters of dark lines could potentially be formed by flowing, salty water, though the observations reported in this study do not prove that.
