With its Gamma Ray Spectrometer (GRS), the spacecraft detected high densities of ice in both hemispheres of Mars.

Numerous images captured by the GRS—which depict everything from branching valleys to apparent emptied-lake formations—have advanced the notion that Mars at one time consisted of vast bodies of water.

Prior to the mid-1960s, it was believed that Mars would consist of oceans and land.

Along with this theory, the planet's darker spots were thought to be the long-distance impressions of large bodies of water.

Judging from their apparent agedness and patterns, the streaks are believed to have formed during possible periods of water flow, such as when temperatures have exceeded –10 °F (Gross).

The downward marks that are seen in the MRO images are referred to as recurring slope lineae (RSL).kilometers of Mars—suggests that Mars has been an exceedingly dry planet for millions of years.Shortly after NASA lost contact with the MGS, photographic evidence was released of two craters—Terra Sirenum and Centauri Montes—that look as though they carried water.For decades, scientists have asserted that life on Mars would be all the more possible with the presence of a water supply.As evidence mounts regarding the impacts of global warming here on Earth, some people believe that Martian colonization could be a necessity in the future.Discoveries made during that probe included the presence of river beds and indications of water deposition, but the most significant finding was the massive Valles Marineris: a 2,500-mile canyon spread that was named in honor of the Mariner spacecraft (Redd).During the Viking space probes of the late 1970s, scientists gained a newfound understanding of the potential impacts of water across the surface of Mars.The presence of salt along the RSL has raised the possibility of flowing brine during certain periods of time.Temperatures on Mars hover around –81 °F, which is roughly 120 degrees below the average temperatures here on Earth (Gruben).In the Nili Fossae area of Mars, the MGS' Thermal Emission Spectrometer (TES) found a high concentration of olivine: a common mineral on Earth's subsurface that weathers into the likes of chlorite and maghemite when placed in contact with water.The presence of olivine—which is now believed to encompass at least 113,000 sq.
