Flowing liquid water has been found on mars, confirming long-standing speculation regarding some anomalous features imaged by orbiting space probes — and further increases the chances of finding living organisms on the Red Planet.

In an announcement made by NASA on Sept. 28, they revealed the findings of a study into images of dark streaks on the slopes of some Martian hillsides during periods where the temperature rises above -23ºC during the summer season, dubbed "recurring slope lineae", that were speculated to be flowing water. While evidence has been found for the presence of ancient Martian oceans, this is the first evidence of present-day water.

The Mars Curiosity rover has taken a picture of a rock formation that looks for all the world like a spoon that is floating above the ground.

NASA has identified the spoon-like object as a ventifact, which is a rock that has been shaped by the wind, slowly sandblasted over time into its present shape, and held in place on its parent rock formation at the end of it’s handle. Mars’s lower gravity, approximately one-third that of Earth’s, has also probably helped prevent the spoon’s snapping off under it’s own weight. There are a number of other ventifacts present in the picture as well, but none quite as dramatic as the levitating Martian utensil.

A lucky accident aboard the Curiosity Rover has confirmed that there is life on Mars. A life-detection experiment conducted by the Viking lander in 1976 generated a pattern of responses that fulfilled criteria for the presence of life on the planet, but the results were dismissed by JPL experts. Over the years that followed, this conclusion came into serious question, and a paper published in the International Journal of Aeronautical and Space Sciences in March of 2012 presented convincing evidence that the earlier analysis of the data was flawed. Now the leak in Curiosity’s wet chemistry test has confirmed the presence of gasses that can only be created by living organisms.read more

This is not a morality tale about planetary preservation – and what happens if you don’t take good care of your literal ground of being. But after years of assuming that Mars is and always had been inhospitable to life, scientists at NASA are now convinced that an ocean once covered 20% of the surface of Mars. In some places, the ocean was likely a mile in depth. And according to Charles Cockell, a professor of astrobiology at Edinburgh University, “The longer water persists on a planetary body in one location, particularly if there is geological turnover, the more likely it is that it would provide a habitable environment for a suitable duration for life to either originate or proliferate. An ocean would meet this need.”
