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.From the latest images of the RSL, it's the darker streaks that are believed to be the marks of hydration.
Therefore, water could never exist in the areas where the spacecraft landed, though ice could possibly turn to water if mixed with salt.
Further observations of this probe included the possibility of past floods, which was suggested by the way that certain rocks were stacked in the Pathfinder's viewing range.
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).
Due to Mars' colder atmosphere, science has only been able to determine the presence of ice on the red planet.
However, the combination of salt and ice raises the possibility of water under certain temperatures because the mineral causes ice to melt; it's a process applied on Earth's roads whenever icy conditions take hold.
Since the first Martian probe in the early 1970s, NASA has found evidence that water could possibly exist on Mars.
These latest findings, however, are distinguished by the discovery of hydrated salts, which are formed by a combination of sodium chloride compounds and water molecules.
28, NASA unveiled new evidence that water exists on Mars.
The discovery was made through images captured by the space agency's Mars Reconnaissance Orbiter (MRO) spacecraft, which was launched in the mid-2000s to explore the red planet's atmosphere.
