NASA's MRO Sees Possible Martian Water Flows
Observations from NASA's Mars Reconnaissance Orbiter, MRO, have revealed possible flowing water during the warmest months on Mars. Scientists discuss the findings at a NASA Headquarters news briefing held August 4, 2011. Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars' southern hemisphere.
