NASA has confirmed the evidence of Water on Mars. We take a look at some of the pictures that NASA has released in this context, both recently and earlier. In this picture: Dark, narrow streaks on Martian slopes such as these at Hale Crater are inferred to be formed by seasonal flow of water on contemporary Mars. The streaks are roughly the length of a football field. (Source: Source: NASA/JPL-Caltech/Univ. of Arizona)
NASA has found more evidence of water in other parts of Mars as well. In this picture, the Dark narrow streaks, called "recurring slope lineae," emanate from the walls of Garni Crater on Mars. The streaks are believed to be formed by the flow of briny liquid water on Mars. (Source: NASA/JPL-Caltech/Univ. of Arizona )
The dark, narrow streaks flowing downhill on Mars at sites such as this portion of Horowitz Crater are inferred to be formed by seasonal flow of water on modern-day Mars. (Source: NASA/JPL-Caltech/Univ. of Arizona )
In this picture, that was released in 2011, portions of the Martian surface shot by NASA's Mars Reconnaissance Orbiter show many channels from 1 meter to 10 meters wide on a scarp in the Hellas impact basin. Researchers found telltale fingerprints of salts that form only in the presence of water in narrow channels cut into cliff walls throughout the planet's equatorial region.

These images come from observations of Newton crater released in 2011, shows warm-season features that might be seen as evidence of salty liquid water active on Mars. The features that extend down the slope during warm seasons are called recurring slope lineae believed to be formed by salty water flowing down. (Source: NASA/JPL-Caltech/Univ. of Arizona)
