At 11 a.m. EDT on October first, the eighteenth tropical depression of the Eastern Pacific hurricane season was born. He's a little guy, but is likely going to grow up to be a tropical storm and get the name Olaf later today or tomorrow. He's not, however, expected to reach hurricane strength.
Warnings have been posted in the extreme northeastern Philippines as Parma has powered up into a Super Typhoon, and its new forecast track takes it over the northeastern tip of the Philippines, and three NASA satellites are keeping tabs on it.
The Tropical Rainfall Measuring Mission or TRMM satellite, orbits the Earth and measures the amount of rainfall created by a tropical cyclone. When Typhoon Ketsana (known in the Phillippines as "Ondoy") made landfall early this past weekend TRMM was monitoring its rainfall. That data was used to create a 3-D map of rainfall over the Philippines from September 21-28.
WASHINGTON - During its 2009 annual meeting, the National Academy of Engineering (NAE) will present two awards for extraordinary impacts on the engineering profession. The Academy's Founders Award will be given to JOHN CASANI, who has made important contributions to deep space exploration, and SHEILA WIDNALL will receive the Arthur M.
Two tropical cyclones in the Western Pacific are keeping in tune to the 1969 hit song by the Beatles, "Come Together." Tropical Depression 18W and Tropical Storm Parma are already beginning to merge now that 18W made landfall in Guam and dissipated. 18W did bring gusty winds and heavy downpours to Guam, and will continue to affect the surf over the next day or two.
NASA's Aqua satellite flew over Typhoon Ketsana during its lifetime and captured infrared imagery on a daily basis. The images showed high, cold, thunderstorm cloud tops (purple) as cold as -63F, as they dumped heavy rains over the northern Philippines and Vietnam.
(Washington, DC ? Sept. 30, 2009) -- Completing an 18-month mission orbiting the Earth more than 6,000 times on-orbit the International Space Station (ISS), the Optical Reflector Material Experiment (ORMatE-1) returns to Washington, D.C., to NRL's Electronics Science and Technology Division to begin experiment testing and analysis.
Planning a trip to Mars? Take plenty of shielding. According to sensors on NASA's ACE (Advanced Composition Explorer) spacecraft, galactic cosmic rays have just hit a Space Age high.
WASHINGTON -- Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources, says a new report by the National Research Council.
NASA's MESSENGER spacecraft, which is toting an $8.7 million University of Colorado at Boulder instrument, will make its third and final flyby of Mercury on Sept. 29 -- a clever gravity-assist maneuver that will steer it into orbit around the rocky planet beginning in March 2011.
Astronomers using the twin 10-meter telescopes at the W. M. Keck Observatory in Hawaii have explored one of the most compact dust disks ever resolved around another star. If placed in our own solar system, the disk would span about four times Earth's distance from the sun, reaching nearly to Jupiter's orbit.
Scientists are seeing sub-surface water ice that may be 99 percent pure halfway between the north pole and the equator on Mars, thanks to quick-turnaround observations from orbit of fresh meteorite impact craters on the planet.
GREENBELT, Md. -- 28 times per second, engineers at NASA's Goddard Space Flight Center fire a laser that travels about 250,000 miles to hit the minivan-sized Lunar Reconnaissance Orbiter (LRO) spacecraft moving at nearly 3,600 miles per hour as it orbits the moon.
PROVIDENCE, R.I. [Brown University] -- In a discovery that promises to reinvigorate studies of the moon and potentially upend thinking of how it originated, scientists at Brown University and other research institutions have found evidence of water molecules on the surface of the moon.
GREENBELT, Md. -- A NASA team is developing a transparent coating that mimics the self-cleaning properties of the lotus plant to prevent dirt from sticking to the surfaces of spaceflight gear and bacteria from growing inside astronaut living quarters.
