...mention cooling to the researchers behind the Phoenix Mars Lander. Their ship will have just six months to sample and study the water ice at the Martian north pole before -200°F (-130°C) winter temperatures hit the region. "We last until the sun goes down. Then we freeze to death," says principal investigator Peter Smith, a planetary scientist at the University of Arizona, Tucson. Before it does, Phoenix Lander will probably offer a first look at actual Martian water ice rather than the dry water scars of millenniums past. To do that, the lander will...
...moment long awaited by NASA scientists, the unmanned orbiter Cassini will pass through geysers of ice, water vapor and dust erupting from the southern pole of the 310-mile-wide moon Enceladus, in hopes of collecting fine particles. The 465-mile-high plumes shooting out from fissures, or tiger stripes, in the moon's surface, were first discovered during a similar but much more distant flyby...
...This will be our closest flyby yet," says NASA scientist Candice Hansen-Koharcheck. "We knew that Enceladus was a very interesting target, but we had no idea that we would find the kind of activity that we found - water just spewing out of the south pole...
...addition to collecting particles for analysis in an ion and neutral mass spectrometer, and a cosmic dust analyzer, Cassini will photograph yet unseen parts near the moon's south pole. It will also use infrared technology to create a comprehensive map of surface temperatures at the south pole. Warmer temperatures increase the likelihood that there is water in liquid form on the small moon...
...respectively. Junior Becky Christensen’s 1.79m clearance in the high jump came up just one centimeter short of her personal indoor best, but provisionally qualifies her for the NCAAs. Co-captain Sally Stanton and senior Clara Blattler cleared 3.55m and 3.85m, respectively, in the pole vault, while senior Danielle Mirabal finished eighth in the 60-meter dash. Senior Brittan Smith led the women in the field events with a second-place leap of 6.00m. Co-captain Alex Lewis finished sixth in the men’s heptathlon with 5112 points...
