U.S. Scientists Confirm Water on Mars

NASA scientists said that Mars was covered once by vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life.
Laboratory tests aboard NASA’s Phoenix Mars Lander have identified water in a soil sample; the lander’s robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples.
"We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA "This is the first time Martian water has been touched and tasted. "
The robotic arm is a critical part of the Phoenix Mars mission. It is needed to trench into the icy layers of northern polar Mars and deliver samples to instruments that will analyze what Mars is made of, what its water is like, and whether it is or has ever been a possible habitat for life.
The soil sample came from a trench approximately 2 inches deep. When the robotic arm first reached that depth, it hit a hard layer of frozen soil. Two attempts to deliver samples of icy soil on days when fresh material was exposed were foiled when the samples became stuck inside the scoop. Most of the material in Wednesday’s sample had been exposed to the air for two days, letting some of the water in the sample vaporize away and making the soil easier to handle.
"Mars is giving us some surprises," said Phoenix principal investigator Peter Smith of the University of Arizona. "We’re excited because surprises are where discoveries come from. One surprise is how the soil is behaving. The ice-rich layers stick to the scoop when poised in the sun above the deck, different from what we expected, from all the Mars simulation testing we’ve done so far."
Since landing on May 25, Phoenix has been studying soil with a chemistry lab, TEGA, a microscope, a conductivity probe and cameras. The science team is trying to determine whether the water ice ever thaws enough to be available for biology and if carbon-containing chemicals and other raw materials for life are present.
The mission is examining the sky as well as the ground. A Canadian instrument is using a laser beam to study dust and clouds overhead.
"It’s a 30-watt light bulb giving us a laser show on Mars," said Victoria Hipkin of the Canadian Space Agency.
A full-circle, color panorama of Phoenix’s surroundings also has been completed by the spacecraft. "The details and patterns we see in the ground show an ice-dominated terrain as far as the eye can see," said Mark Lemmon of Texas A & M University, lead scientist for Phoenix’s Surface Stereo Imager camera. "They help us plan measurements we’re making within reach of the robotic arm and interpret those measurements on a wider scale. /

? ?One of the most mysterious archaeological spectacles in the world is the immense complex of geometrical symbols, giant ground-drawings of birds and animals, and hundreds of long, ruler-straight lines, some right across mountains, which stretch over 1,200 square miles of the Peruvian tablelands, at Nazca.
? ?Nazca was first revealed to modern eyes in 1926 when three explorers looked down on the desert from a hillside at dusk and briefly saw a Nazca line highlighted by the rays of the sun. But it was not until the Peruvian airforce took aerial photographs in the 1940s that the full magnificence of the panorama was apparent. Hundreds of what looked like landing strips for aircraft were revealed. There were eighteen bird-like drawings, up to 400 feet long, four-sided figures with two lines parallel; and long needle-like triangles which ran for miles. Among the many abstract patterns were a giant spider, a monkey, a shark, all drawn on the ground on a huge scale.
? ?The scale is monumental, but from the ground almost invisible and totally incomprehensible. The amazing fact about Nazca, created more than 1,500 years ago, is that it can only be appreciated if seen from the air. Many, therefore, regarded it as a prehistoric landing ground for visitors from outer space, but Jim Woodman, an American explorer, who was long fascinated by the mystery of Nazea, had a different opinion. He believed that Nazca only made sense if the people who had designed and made these vast drawings on the ground could actually see them, and that led him to the theory that the ancient Peruvians had somehow learned to fly, as only from above could they really see the extent of their handiwork. With this theory in mind, he researched into ancient Peruvian legends about flight and came to the conclusion that the only feasible answer was a hot-air balloon.
? ?To prove his theory, Woodman would have to make such a thing using the same fabrics and fibers that would have been available to the men of Nazca at the time. He started by gathering information from ancient paintings, legends, books and archaeological sites. After many attempts, Woodman built a balloon-type airship. It took him into the air, letting him have the sensation he had never had from viewing the same ground that he had seen many times. His flight was a modern demonstration of an ancient possibility.
One of the “most mysterious archaeological spectacles in the world” is______.

A:the size of Nazca B:the lines over mountains C:the Peruvian tablelands D:the huge and complicated ground-drawings
