Evidence of flowing water has been found on Mars. Images sent back by NASA's Mars Reconnaissance Orbiter (MRO) spacecraft reveal dark streaks on sandy slopes on the Red Planet that scientists believe are made by flowing water. The streaks are probably made by brine that runs down steep ...
All evidence points to the fact that Mars once had flowing water, but numerous flybys, orbiters and landers have confirmed one undeniable fact — any liquid (液体的) water that was once on its surface is now long gone. One idea, the Mars Ocean Hypothesis, suggests that Mars not only ha...
Photographic evidence suggests that liquid water once existed in great quantity on the surface of Mars. Two types of flow features are seen: runoff channels and outflow channels. Runoff channels are found in the southern highlands. These flow features are extensive systems—sometimes hundreds of kil...

○Although some researchers claim that Mars may once have had oceans, others dispute this, pointing to an absence of evidence or offering alternative interpretations of evidence. ○Various types of images have been used to demonstrate that most of Martian surface contains evidence of flowing water....

They're are thought to have been formed by flowing water on Mars. NASA/JPL/University of Arizona Liquid water is essential for life, including microbial life. At least that's the case here on Earth and presumably, the same goes for arid Mars. That's the assumption that governed NASA's...
Scientists think that flowing Martian groundwater formed these crevices in the planet's distant past. The Mars Reconnaissance Orbiter wasn't the only spy on the red planet over the last year. While the orbiter examined Mars from space, the Phoenix Mars Lander entered the planet's ...
