This 23 March, 2004 NASA Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a crater in Utopia Planitia on Mars. There used to be an ocean on Mars about three billion years ago and its remains can still be observed, Russian scientists said. “Our studies have shown that an ocean existed in the Utopia Planitia region on the Red Planet,” Mikhail Ivanov from Space Research Institute of... 

The rover Curiosity has discovered water in fine-grained soil on the surface of Mars, NASA confirmed Thursday in a series of papers published in the journal Science. Each cubic foot of Martian soil contains about two pints of liquid water, though the molecules are bound to other minerals in the soil. Curiosity first landed on Mars in August 2012 on Gale Crater, near the equator of the planet. Its... 

Click on the image to enlarge it. NASA scientists recently discovered an underground dry ice lake containing more carbon dioxide than originally thought. The trapped carbon dioxide is thought to have come from the planet’s atmosphere earlier in its history when it was conducive for life on Mars to exist. “It really is a buried treasure,” said Jeffrey Plaut, a scientist of the NASA... 

Spirit, the poor Mars Rover that’s been stuck in Martian sand since last year, has actually contributed to a pretty fantastic discovery in its sedentary months: the evidence of subsurface water on Mars. To recap: Spirit, one of two plucky Mars Rovers that had finished their initial missions in 2004 and had embarked upon, as NASA calls them, “bonus missions” ever since, slipped through... 

Mystery ... scientists are already planning more missions to Mars NASA scientists last night unveiled compelling evidence of life on Mars. A special mission to the Red Planet has revealed the likely presence of a form of pond scum – the building blocks of life as we know it. NASA unveiled the results of the recent Opportunity and Spirit probes sent millions of miles through the solar system to...
