 Tucson AZ (SPX) Sep 17, 2009 
Scientists from the Tucson-based Planetary Science Institute have created the first detailed maps that show the amount of dry ice (solid carbon dioxide) deposited in the polar regions of Mars. The maps reveal how the ice thickness varies with the seasons. The maps were created from measurements taken by the Mars Odyssey neutron spectrometer, said PSI Senior Scientist Thomas H. Prettyman ... read more 
Greenbelt MD (SPX) Sep 17, 2009In the early 1980s, scientists at NASA's Goddard Space Flight Center, Greenbelt, Md., developed the Normalized Difference Vegetation Index (NDVI), an innovative combination of two satellite measurements that allowed them to analyze changes in the "greenness" of Earth as viewed from space. Much like measurements from weather satellites allow meteorologists to track and monitor hurricanes, ND ... more |

Manoa HI (SPX) Sep 17, 2009A team of University of Hawai'i at Manoa researchers led by Ralf Kaiser, physical chemist at UH Manoa, unraveled the chemical evolution of the orange-brownish colored atmosphere of Saturn's moon Titan, the only solar system body besides Venus and Earth with a solid surface and thick atmosphere. The UH Manoa team, including Xibin Gu and Seol Kim, conducted simulation experiments mimicking ... more  
Greenbelt MD (SPX) Sep 17, 2009NASA's James Webb Space Telescope is starting to come together. A major component of the telescope, the Integrated Science Instrument Module structure, recently arrived at NASA Goddard Space Flight Center in Greenbelt, Md. for testing in the Spacecraft Systems Development and Integration Facility. The Integrated Science Instrument Module, or ISIM, is an important component of the Webb tele ... more  
Washington DC (SPX) Sep 17, 2009Armadillo Aerospace this past week successfully flew its Scorpius vehicle twice in two hours between a pair of landing pads to qualify for the $1 million top prize in NASA's Northrop Grumman Lunar Lander Challenge. The milestone event paves the way for higher-altitude flights by the Armadillo Aerospace team, and demonstrated the value of prizes to stimulate innovation. Other entrants ... more |

Los Angeles CA (SPX) Sep 17, 2009Astronomers from the University of California, Los Angeles and the University of Hawaii have discovered multiple fragments ejected during the largest cometary outburst ever witnessed. Images and animations showing fragments rapidly flying away from the nucleus of comet 17P/Holmes will be presented by Rachel Stevenson at the European Planetary Science Congress in Potsdam, Germany, on Wednesday 16 ... more  
Garching, Germany (SPX) Sep 17, 2009The longest set of HARPS measurements ever made has firmly established the nature of the smallest and fastest-orbiting exoplanet known, CoRoT-7b, revealing its mass as five times that of Earth's. Combined with CoRoT-7b's known radius, which is less than twice that of our terrestrial home, this tells us that the exoplanet's density is quite similar to the Earth's, suggesting a solid, rocky world. ... more 
Berlin, Germany (SPX) Sep 17, 2009A team of international scientists led by Mirjam Langhans, from the German Aerospace Center (DLR), will present first results of a global analysis of spatial patterns, occurrence and origin of river channels on Titan at the European Planetary Science Congress in Potsdam, Germany, on Wednesday 16 September. To date scientists have focused their investigations on single channels due to the ... more |
