...following system checks and the capture of hundreds of images from stereoscopic cameras, the stationary probe will begin its search for frozen water. Scientists say Mars was once flush with rivers and lakes, but most of the water escaped into space due to the planet's low gravity and thin atmosphere. What's left is believed to be concentrated at the poles. Phoenix will soon begin digging for it, extending an 8 ft. (2.35 m) robotic arm outfitted with a movable scoop. First, however, scientists will use landing-site images to build a virtual 3-D computer...
Mars, as scientists now know, was once a very wet planet, running with rivers and teeming with oceans and seas much like the Earth. But its low gravity and thin atmosphere allowed most of that water to vanish into space. What was left retreated into the subsoil or, significantly, contracted into the poles. Phoenix, a stationary lander in the style of the old Viking ships that touched down on the planet in 1976, will get a chance to dig into that frozen polar rind...
Earlier in the month, a female student was attacked while leaving Lamont Library by an unidentified male who approached her from behind and wrapped a thin wire around her neck. The victim was able to escape, but the incident raised considerable alarm as news of the attack spread through campus mailing lists...
...plaque that was building up inside it. The concern: that some of that arterial plaque might break off and form a clot in the Senator's brain, interrupting the flow of blood to his cerebrum. After the operation, he was probably also given aspirin or other medications to thin his blood and decrease the risk that he would form a clot...
...blood thinners. This is apparently what happened to Israeli Prime Minister Ariel Sharon, who was given blood thinners after he suffered an earlier minor stroke and is still in a coma. News reports have not indicated whether Sen. Kennedy is on medication to thin his blood...
