Huygens Establishes Pebble Sizes On Titan![]() An unexpected radio reflection from the surface of Titan has allowed ESA scientists to deduce the average size of stones and pebbles close to the Huygens' landing site. The technique could be used on other lander missions to analyze planetary surfaces for free. When Huygens came to rest on the surface of Titan on 14 January 2005, it survived the impact and continued to transmit to the Cassini mothership, orbiting above. Cassini Radar Spots Great Lakes On Titan ![]() The Cassini spacecraft, using its radar system, has discovered very strong evidence for hydrocarbon lakes on Titan. Dark patches, which resemble terrestrial lakes, seem to be sprinkled all over the high latitudes surrounding Titan's north pole. Model Finds Exoplanet Capable Of Supporting Life ![]() The steady discovery of giant planets orbiting stars other than the Sun has heightened speculation that there could be Earth-type worlds in nearby planetary systems capable of sustaining life. Now researchers have found one that could have formed an Earth-like planet. |
Vibro-Acoustic Tests On Webb Telescope Primary Mirror Completed![]() In an ongoing demonstration of the technological readiness of the James Webb Space Telescope, a team led by Northrop Grumman and Ball Aerospace successfully completed several rigorous tests that proved the primary mirror for the telescope can successfully withstand launch and function as planned in its space environment. Lockheed Martin Announces 2nd Quarter Results ![]() Lockheed Martin reported Tuesday its second quarter net earnings were $580 million ($1.34 per diluted share) compared to $461 million ($1.02 per diluted share) in 2005. Syracuse 3B Satellite Readied For Launch ![]() Arianespace's upcoming Ariane 5 ECA flight will match a range of payloads for its dual-satellite launch. The next mission, scheduled for Aug. 11, will carry France's Syracuse 3B military relay platform, along with the civilian JCSAT-10 telecommunications spacecraft for Japan's JSAT Corp. |

Research Sheds New Light On Quasars![]() In the distant, young universe, quasars shine with brilliance unmatched by anything in the local cosmos. Although they appear starlike in optical telescopes, quasars are actually the bright centers of galaxies located billions of light-years from Earth. Spitzer Spies Building Blocks Of Life In Supernova Remnant ![]() In 1987 a massive star exploded in a neighboring galaxy, an event called a supernova. It was the closest supernova to Earth since the invention of the telescope centuries ago. SMART-1 Sees Lava-Filled Crater ![]() This image, taken by the advanced Moon Imaging Experiment on board ESA's SMART-1 spacecraft, shows crater Lomonosov on the Moon's far side. AMIE obtained the image on Jan. 30 from a distance of about 2,100 kilometers (1,300 miles) from the surface, with a ground resolution of 190 meters (617 feet) per pixel. |
New Camera Enhances Forecasting Of Sun-Generated Storms![]() Every 100-plus minutes, while orbiting approximately 50 miles above the Earth onboard the Coriolis satellite, the Solar Mass Ejection Imager experiment scans the darkness of space-seeking, sun-generated magnetic clouds of particles intent on striking the planet. Orbital and Rocketplane Kistler Announce Strategic Relationship ![]() Rocketplane Kistler and Orbital Sciences announced Tuesday that they have entered into a strategic relationship to support the NASA COTS program and other applications of RpK's innovative space transportation system. NASA Experiment Finds Possible Trigger For Radio-Busting Bubbles ![]() NASA-funded researchers have identified a possible cause of giant bubbles that often form above the equator in the electrically charged upper atmosphere. |
Illicit Trade Led To Modern Globalization![]() In a forthcoming study from the American Journal of Sociology, Emily Erikson and Peter Bearman (Columbia University) demonstrate that an early example of globalization was the direct result of individual malfeasance, specifically, private trade using company resources. Cover-up claims as China storm toll leaps to 530 ![]() Chinese officials were warned against cover-ups on Saturday after the death toll from a tropical storm more than doubled overnight. Scientists Strengthen Case For Life More Ancient Than Previously Thought ![]() Ten years ago, an international team of scientists reported evidence, in a controversial cover story in the journal Nature, that life on Earth began more than 3.8 billion years ago--400 million years earlier than previously thought. New Study Fuels Louisiana Subsidence Controversy ![]() While erosion and wetland loss are huge problems along Louisiana's coast, the basement 30 to 50 feet beneath much of the Mississippi Delta has been highly stable for the past 8000 years with negligible subsidence rates.
