There’s no shortage of news out of our nearest planetary neighbor, Mars. The latest includes new information leading scientists to believe water currently exists and flows on the red planet in liquid form. And today a study has been published in Science suggesting that liquid water was stable on the surface for up to 10,000,000 years.
The Curiosity rover has been studying Gale crater for over 2 years measuring the geometry and grain sizes of the strata. What they have found is that gravel and sand have eroded from the crater’s northern wall and were transported south in shallow streams. The deposits accumulated toward the interior of the crater and later relocated by wind-driven erosion. They conclude that the water table had to have been tens of meters deep to explain the accumulation in the delta and deposits in the lakes. This may suggest a much warmer and wetter climate in Mars’ past than previously thought, and over a long enough time table to support the idea of life on the planet.
This is an exciting time for space exploration, here’s to hoping for a manned mission to Mars in our lifetime! Take a look at the study.
