Recurring slope lineae discovered deep in Valles Marineris
Discovered in 2011, recurring slope lineae (RSL for short) are narrow, dark lines on steep slopes. They appear and grow longer during the warmest time of year, then fade and disappear over winter. They recur in the same places the … Continue reading

Salty flows on Mars
The features known as “recurring slope lineae” (RSL) are the best evidence going that liquid water can, and does, flow on present-day Mars. The lineae are small dark streaks that appear mostly on equator-facing slopes, are associated with slope channels, … Continue reading

Seasonal flows of water on Mars
Finding water on Mars is nothing new. Scientists have known for years that water (as ice) lies in the polar caps and underground in high latitudes. However images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars … Continue reading
