Icebridge To Study Arctic GlaciersGreenbelt MD (SPX) Mar 19, 2010 NASA's Operation IceBridge mission, the largest airborne survey ever flown of Earth's polar ice, kicks off its second year of study when NASA aircraft arrive in Greenland March 22. The IceBridge mission allows scientists to track changes in the extent and thickness of polar ice, which is important for understanding ice dynamics. IceBridge began in March 2009 as a means to fill the gap in polar observations between the loss of NASA's Ice, Cloud and land Elevation Satellite, or ICESat, and the launc ... read more |

Historic Deep Space Network Antenna Starts Major Surgery
Pasadena CA (JPL) Mar 10, 2010Like a hard-driving athlete whose joints need help, the giant "Mars antenna" at NASA's Deep Space Network site in Goldstone, Calif. has begun major, delicate surgery. The operation on the historic 70-meter-wide (230-foot) antenna, which has received data and sent commands to deep space missions for over 40 years, will replace a portion of the hydrostatic bearing assembly. This assembly ena ... more Poland to host U.S. missiles in April

Is That Titan Or UtahPasadena CA (JPL) Mar 08, 2010 Planetary scientists have been puzzling for years over the honeycomb patterns and flat valleys with squiggly edges evident in radar images of Saturn's moon Titan. Now, working with a "volunteer researcher" who has put his own spin on data from NASA's Cassini spacecraft, they have found some recognizable analogies to a type of spectacular terrain on Earth known as karst topography. At a poster session on Thursday, March 4, at the Lunar and Planetary Science Conference in The Woodlands, Texas, displays th ... read more |
