Long ago, Mars had massive watersheds—now finally mapped
What can mapped drainage systems on Mars teach scientists about the red planet's watery past? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of scientists from the University of Texas at Austin (UT Austin) conducted a first-time mapping study involving Martian river basins. This study has the potential to not only gain insight into ancient Mars and how much water existed there long ago, but also develop new methods for map…

Mars - The Search Begins (1974): #Mars, including speculation on what form that life might take, many of the core ideas are still current 1/2 century on. The film was made just before NASA's Viking landers were launched in 1975 to begin the search but after the great success of the orbiter Mariner 9 - Olympus Mons was still called Nix Olympica and model makers believed that the sky over the Martian landscape was a deep blue.
