GREENBELT, Md. -- The NASA National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) has successfully completed its most comprehensive end-to-end compatibility test of the actual satellite and all five scientific instruments at Ball Aerospace & Technologies Corp's production and test facility in Boulder, Colo.

Former Tropical Storm Emily made a brief comeback this weekend after degenerating over the mountains of Hispaniola late last week, and NASA's Aqua satellite captured an image of Emily just after her "rebirth."
At 5 p.m. EDT on Saturday, August 6, Emily became a tropical depression for the second time in her life about 70 miles west-northwest of Great Abaco Island, near 26.9 North and 78.1 West. She was moving to the north at 8 mph and had a minimum central pressure of 1012 millibars. Maximum sustained winds were 30 mph.
Tropical Storm Muifa is filling up the Yellow Sea on NASA satellite imagery as it continues moving north today to a landfall in East China's Shandong province. NASA's Aqua satellite captured visible and infrared imagery that shows Muifa's cloud cover stretches across the Yellow Sea, from China to the west to South and North Korea to the east.
Emily is now a surface trough or elongated area of low pressure. The National Hurricane Center noted that Emily's remnants contain a large area of cloudiness and thunderstorms extending from eastern Cuba northeastward across the southeastern Bahamas.
There's a good chance that Emily can make a comeback and get her act together on the weekend as upper-level winds become more favorable. The National Hurricane Center gives Emily a 60% chance of making that comeback over the weekend.
In one image, NASA's Aqua satellite captured two tropical cyclones in the western North Pacific today, Tropical Storm Merbok and the large Typhoon Muifa. NASA Satellite imagery shows that Muifa is almost twice as big as Merbok.
Warmer cloud top temperatures mean that cloud heights in a tropical cyclone are dropping and the storm doesn't have as much power to push them higher in the atmosphere. That's what NASA infrared satellite imagery has revealed about Tropical Storm Eugene this morning.
During the very early morning hours (Eastern Daylight Time) on August 5, Eugene was still hurricane strength. Then the storm ran into cooler waters and a more stable atmosphere, weakening into a tropical storm.
A newly released image from ESA's Mars Express shows the north pole of Mars during the red planet's summer solstice. All the carbon dioxide ice has gone, leaving just a bright cap of water ice.
This image was captured by the orbiter's High-Resolution Stereo Camera on 17 May 2010 and shows part of the northern polar region of Mars during the summer solstice. The solstice is the longest day and the beginning of the summer for the planet's northern hemisphere.
Dark, finger-like features that appear and extend down some Martian slopes during the warmest months of the Mars year may show activity of salty water on Mars. They fade in winter, then recur the next spring.
Repeated observations by the HiRISE camera currently orbiting Mars aboard NASA’s Mars Reconnaissance Orbiter have tracked seasonal changes in these recurring features on several steep slopes in middle latitudes of Mars' southern hemisphere. Some aspects of the observations still puzzle researchers.
Deerfield, IL (Aug. 3, 2011) – An examination of the world's largest river basins found nutrient-rich and powerful river discharges led to spikes in the blooms of plankton associated with cholera outbreaks. These increased discharges often occur at times of increased temperature in coastal water, suggesting that predicting global warming's potential temperature effect on cholera will be more complicated than first thought, according to a new study published today in the American Journal of Tropical Medicine and Hygiene.
(SACRAMENTO, Calif.) — In the first nationwide study of stray-bullet shootings, Garen Wintemute, professor of emergency medicine and director of the Violence Prevention Research Program at UC Davis School of Medicine and Medical Center, quantifies mortality and injury among victims of these unexpected events. His research is published as a letter in the August 3 issue of the Journal of the American Medical Association.
In August of 2016, when NASA's Juno Mission begins sending back information about the atmosphere of the planet Jupiter, research done by Georgia Institute of Technology engineers using a 2,400-pound pressure vessel will help scientists understand what the data means. The Juno probe is scheduled to be launched August 5 from Cape Canaveral Air Force Station in Florida.
A new customised IT business management system developed by Queensland University of Technology (QUT) researchers and capable of improving the scheduling of resources and workflow in surgical theatres has been successfully demonstrated in a German hospital.
Dr Chun Ouyang, from QUT's Business Process Management (BPM) group, said the system was built based on an automated workflow system known as YAWL, and allowed hospitals to more efficiently manage the co-ordination of expensive surgery-related resources.
The majority of stars with more than half of the mass of our Sun form in groups, called open clusters. These clusters are the building blocks of galaxies and vital for the formation and evolution of galaxies such as our own. However, stellar clusters form in very dusty regions that diffuse and absorb most of the visible light that the young stars emit, making them invisible to most sky surveys, but not to the 4.1-m infrared VISTA telescope.
SANTA CRUZ, CA--The mountainous region on the far side of the moon, known as the lunar farside highlands, may be the solid remains of a collision with a smaller companion moon, according to a new study by planetary scientists at the University of California, Santa Cruz.
