The possibility of life on Mars just became a little more realistic: Mars has a summer season when salty streams of water flow across the surface, before freezing again in winter, NASA announced on Monday, indicating the red planet could currently have life on its surface.
“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,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington. “This is a significant development, as it appears to confirm that water — albeit briny — is flowing today on the surface of Mars.”
