Mars Water Speculation
Began In The 1870s

CAPE CANAVERAL, Fla. - The idea that water might be present on Mars, making it possibly suitable for humans, goes back to the late 1870s.
 
That's when Italian astronomer Giovanni Schiaparelli spotted what he described as "canali" on the red planet's surface. The word means channels but was interpreted as canals, and that's when speculation about a civilization on Mars first arose.
 
With a possible announcement today that water in liquid form might have been spotted beneath the Mars surface by the Global Surveyor spacecraft, scientists anew will be speculating about the possibility of some sort of life there.
 
"We don't know what they found, but it's conceivable water could be seeping out, maybe 200 yards beneath the surface," said John Brandenburg, a physicist with Aerospace Corp., a Washington-based organization that works with NASA and other U.S. government agencies.
 
During the years, Brandenburg also has become known for his investigations of the possibility of water existing on Mars, and in the 1980s speculated that vast oceans may have been present hundreds of millions of years ago.
 
He also is the co-author of a recent book, Dead Mars, Dying Earth, which looks closely at both planets. Since the late 1970s, when the Mariner spacecraft revealed evidence of possible geysers, scientists have been holding out hope that water existed on Mars.
 
But never before has the possibility existed that liquid water could be present on the red planet, Brandenburg said. "This could be a big deal; if you have liquid water, you have bacteria living in it," he said.
 
Last year, NASA hoped that the Mars Polar Lander would detect water ice at the Martian South Pole. But the mission never took place after the spacecraft was destroyed.
 
The discovery of water in the warmer climes of Mars, south of the Martian equator, would be far more significant, Brandenburg said. "Water seepage, rather than ice, is extremely important," he said. "If this discovery is borne, it will hasten a human mission to Mars," Brandenburg added.
