Mimetic Martian water is highly pressurized, experiments show

Science
Oct. 13 (UPI) -- Mars is too cold to host flowing liquid water, but with the right mix of compounds, a water solution could be hiding on and below Mars' surface.New research suggests a solution dubbed "mimetic Martian water" could flow on and beneath the Red Planet's crust. Such a solution could explain the channeling, riveting and other evidence of weathering observed on the Martian surface.But the experiments also suggest such a water solution would be highly pressurized.Martian soil samples collected by NASA's Phoenix Lander in 2009 revealed the presence of calcium and magnesium perchlorate, a powerful oxidant."The discovery of significant amounts of different perchlorate salts in Martian soil gives new insight into the Martian 'riverbeds,'" Lorna Dougan, researcher at the University of...

NASA scientists name Martian crater after Apollo 16 moonwalk mission

Science
June 16 (UPI) -- Earlier this spring, NASA's Mars Exploration Rover, also known as the Opportunity rover, discovered a small Martian crater. The discovery was made on the 45th anniversary of the Apollo 16 mission, NASA's 10th moon landing.This week, NASA scientists announced the name of that newly discovered crater. They call it "Orion Crater" -- an homage to the lunar module that carried astronauts John Young and Charles Duke to the moon and back.The rover's Panoramic Camera snapped photos of Orion Crater on April 26. The depression measures 90 feet across. It's a relatively young crater, no older than 10 million years old."It turns out that Orion Crater is almost exactly the same size as Plum Crater on the moon, which John Young and Charles Duke explored on their first of three moonwalks...
