Latest Breaking News: NASA scientists found proof of Water on Mars > NASA scientists have exposed new proof that briny water flows on Mars during its warmest months, raising chances that life could survive on the Red Planet, the space agency said on Thursday.
NASA first found signs of water on Mars more than a decade ago, but earlier signal were that any existing water would be frozen and intense at the poles.
Recently analyzed images from NASA’s Mars Reconnaissance Orbiter satellite show dark, finger-like features that extend down some slopes and crater walls on the planet during its late spring through summer, fading in the Martian winter.
“This is the best evidence we have to date of liquid water occurring today on Mars,” said Philip Christensen, a geophysicist at Arizona State University, Tempe, in a NASA panel announcing the findings in Washington.
NASA scientists believe that if there is liquid water on Mars, it would be highly salty and lie beneath the surface. That would explain why it would not freeze in the planet’s frigid surface temperatures, which can fall to around 200 degrees below zero Fahrenheit (minus 128 degrees Celsius), or evaporate in its low air pressure.
“It is more like syrup, maybe, in how it flows,” said Alfred McEwen of the University of Arizona, Tucson, and principal investigator in charge of a special camera on the Mars orbiter called a High Resolution Imaging Science Experiment. / Reuters
