Seasonal patterns consistent with briny seeps on Red Planet
Flows of saltwater may ooze from rocky outcrops on Mars. Seasonal dark streaks on some Martian slopes could come from briny water, American and Swiss researchers suggest in the Aug. 5 Science.
Still, the researchers haven’t actually detected any water, frozen or liquid. Nor can they explain how the water would be replenished in the dry, harsh Martian environment.
