Engineers Compete To Find Best Trajectory To Intercept An Asteroid
Noordwijk, The Netherlands (SPX) Feb 2, 2006Experts from across the world are meeting at the European Space Agency's European Space and Technology Research Centre to discuss how to best calculate spacecraft orbits. Even though the space age is now 49 years old, determining the optimal trajectories for spacecraft remains a far from easy task. Deep Impact Team Reports First Evidence Of Cometary Ice 
Providence RI (SPX) Feb 2, 2006Researchers examining data returned by NASA's Deep Impact mission have discovered that Comet Tempel 1 is covered with a small amount of water ice. The results, reported in an advance online edition of the journal Science, offer the first definitive evidence of surface ice on any comet. UA Scientist And Private Collector Form Center To Save Meteorites 
Tucson AZ (SPX) Feb 02, 2006by Lori Stiles The world's meteorites are vanishing. If something isn't done soon, most of Earth's rare space rocks could be gone in a lifetime. |
New Image Shows Speck Of Comet Dust From NASA Mission
Berkeley CA (SPX) Feb 3, 2006This NASA photo shows a mote of comet dust embedded in a tiny wedge of aerogel. It was extracted from the Stardust spacecraft's collectors that returned to Earth Jan. 15. The comet dust was extracted by Christopher Snead, a University of California, Berkeley, researcher using new techniques called nanomanipulation that were developed at the university's Space Sciences Laboratory. Jupiter Trojan Asteroid Binary May Be Icy Comets From Solar Systems Infancy 
Washington DC (SPX) FEB 1, 2006Two tiny planetoids trailing Jupiter in its orbit could provide new clues about the evolution of the solar system. The binaries � one called Patroclus and the other an unnamed companion � once were thought to be tiny asteroids, but the latest research shows they are made of water ice and a thin layer of dust. Stardust Put Into Hibernation 
Pasadena CA (JPL) Jan 31, 2006NASA's Stardust spacecraft was placed into hibernation mode yesterday. Stardust successfully returned to Earth samples of a comet via its sample return capsule on Jan. 15. The spacecraft has logged almost seven years of flight. |

Cracking Open A Vault
Chesapeake Bay VA (SPX) Jan 25, 2006Every hundred thousand years or so, a large asteroid or comet hits the Earth. The explosive force of the impact sends tons of material into the air and punches a big hole in the crust. We don't see a lot of these old craters, however, because Earth is a dynamic environment -- wind, water, and tectonic plate shuffling constantly changes the appearance of the surface. Over time, many impact craters become altered or buried deep underground. Ancient Asteroid Breakup Covered Earth In Dust 
Washington DC (SPX) Jan 18 2006Scientists think they have established a link between an ancient collision in the main asteroid belt and a layer of dust particles deposited on Earth from space soon thereafter. The findings could help identify similar events in the geological record and provide more clues about the history of the solar system. Catalina Sky Survey Tops 2005 NEO Discoveries 
Tuscon AZ (SPX) Jan 19, 2006When it comes to finding asteroids or comets that swing too close to home, the Catalina Sky Survey is currently Earth's best defense. |
French Labs To Receive Stardust Samples
Houston TX (SPX) Jan 19, 2006Returning to Earth last weekend after a seven-year, three-billion mile journey through space, Stardust's Sample Return Canister has now arrived at NASA's Johnson Space Center, in Houston. UW Astronomer Hits Cosmic Paydirt With Stardust 
Seattle WA (SPX) Jan 19, 2006In an experiment using a special air gun, particles were shot into aerogel at high velocities. This closeup shows particles captured in aerogel. The particles leave a carrot-shaped trail in the aerogel. Stardust Safely Home 
Moffett Field CA (SPX) Jan 16, 2006The Stardust sample return capsule gently landed in the U.S. Air Force Utah Test and Training Range this morning at 3:10 a.m. Mountain time. Other than a little mud on its nose, the capsule appeared to be in excellent shape. A helicopter crew collected the capsule and brought it to a clean room at the nearby Michael Army Airfield. The capsule and its precious cargo are now being prepared for shipment to the Johnson Space Center in Houston, Texas. |
