The so-called “Red Planet” has been long though of as arid and dry. This new find means it is possible for life to be sustained on the planet, according to The Telegraph.
Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected […] This is a significant development, as it appears to confirm that water ― albeit briny ― is flowing today on the surface of Mars: John Grunsfeld, astronaut.
The MRO has been examining Mars since 2006. In 2005, radar data revealed the presence of large quantities of water ice at the poles and at mid-latitudes according to Wikipedia. Same source indicates there are 7 active probes on or in-orbit around Mars (5 orbiters and 2 rovers).
