Ancient Flood Channels Cut Deep Into Mars 46
astroengine writes "Relatively recently, water blasted out from an underground aquifer on Mars, carving out deep flood channels in the surface that were later buried by lava flows, radar images complied from NASA's Mars Reconnaissance Orbiter probe shows. The channels are at least twice as deep as previous estimates for Marte Vallis, an expanse of plains just north of the Martian equator that is the youngest volcanic region on the planet. "We see similar channels elsewhere on Mars and they are not filled with lava so it's important to be able to compare different channel systems, and also similar systems on Earth, to give us clues about how they formed," lead researcher Gareth Morgan, with the Smithsonian Institution in Washington DC, told Discovery News."
Bored with Mars (Score:4, Interesting)
Am I the only person bored with the obsessive focusing on Mars by people desperate to find life? Maybe mars had life in the past but now its a dead dustball. There is more change of life in the ice moons of the outer solar system as they have oceans NOW. A few more missions to them and a few less to mars might be a better use of scientific resources.
