Study Suggests Spaceflight May Decrease Human Immunity![]() A NASA-funded study has found the human body's ability to fight off disease may be decreased by spaceflight. The effect may even linger after an astronaut's return to Earth following long flights. Captive Carry Rehearsal Flight Successful; Mach 10 Free Flight Next ![]() NASA aeronautics researchers are looking forward to flying the X-43A research aircraft at speeds up to 10 times the speed of sound later this fall, following a successful "captive carry" dress rehearsal flight from NASA's Dryden Flight Research Center Sept. 27. |
Large Asteroid Zooms Safely Past Earth![]() A mountain-sized asteroid made its closest approach to Earth at 9:35 a.m. Eastern Time on Wednesday, Sept. 29. Although asteroid 4179 Toutatis came no closer than four times the distance between Earth and the Moon (approximately 1.5 million kilometers or 961,000 miles), this is the closest approach of any known asteroid of comparable size this century. Mars Drill Will Seek Knowledge And Resources ![]() It will be drilling for information first, then for resources, though oil is not likely to be among exploration targets. |
Poland Takes Part In Europe's First Satellite Navigation System![]() It is actually possible for everyone to know their coordinates to within an accuracy of 1-2 metres using the European Geostationary Navigation Overlay Service (EGNOS). EGNOS is based on a network of reference stations all over Europe, and a new step towards implementing this network was the recent inauguration of facilities in Poland. Indonesia Launches Scientific Rockets ![]() Indonesia's National Aeronautics and Space Agency (LAPAN) has successfully launched two scientific rockets from the Staspro launch pad at Cilauteureun village in West Java province, on Wednesday, an official said. |
DigitalGlobe, Merrick Extend Reseller Agreement To Service Mexico![]() DigitalGlobe today announced that Merrick Advanced Photogrammetry of the Americas S. de R.L. de C.V. is now an authorized reseller of QuickBird high-resolution satellite imagery in Mexico. MAPA is a wholly owned subsidiary of Colorado-based Merrick & Company. New Surface Chemistry May Extend Technology Life For Making Transistors ![]() Researchers at the University of Illinois at Urbana-Champaign have developed a technique that uses surface chemistry to make tinier and more effective p-n junctions in silicon-based semiconductors. |
Table Top Particle Accelerators One Step Closer![]() Scientists from the UK and the USA have successfully demonstrated a new technique that could help to shrink the size and cost of future particle accelerators for fundamental physics experiments and applications in materials and biomedicine. Laser Wakefield Acceleration: Channeling The Best Beams Ever ![]() Researchers at the Department of Energy's Lawrence Berkeley National Laboratory have taken a giant step toward realizing the promise of laser wakefield acceleration, by guiding and controlling extremely intense laser beams over greater distances than ever before to produce high-quality, energetic electron beams. |
Coming Soon: "Good" Jupiters![]() We tend to think of Earth as the most important planet in our solar system. But if you were to eavesdrop on a group of astronomers from a distant world, discussing their initial investigation of our sun and its planets, Earth might not even be on the agenda. More likely, they'd be talking about Jupiter. The Milky Way Above La Silla ![]() Anybody who visits a high-altitude astronomical observatory at this time of the year will be impressed by the beauty of the Milky Way band that stretches across the sky. Compared to the poor views from cities and other human conglomerations, the dark and bright nebulae come into view together with an astonishing palette of clear stellar colours. |
