Their results show that Saturn's secondary aurora is much more like Jupiter's in origin than it is the Earth's.http://www.sciencedaily.com/releases/2008/06/080619105513.htm Jules Verne Refuels The International Space Station- June 20, 2008 ESA's Jules Verne ATV was used for the first time yesterday to transfer in one step 811 kg of refueling propellant to the International Space Station while the two vehicles orbited Earth at 28 000 kmh. With this premiere for Europe, Jules Verne becomes the first western spaceship to succeed in refueling another space infrastructure in orbit.http://www.sciencedaily.com/releases/2008/06/080618114613.htm Chemical Clues Point To Dusty Origin For Earth-like Planets- June 20, 2008 Higher than expected levels of sodium found in a 4.6 billion-year-old meteorite suggest that the dust clouds from which the building blocks of the Earth and neighboring planets formed were much denser than previously supposed.http://www.sciencedaily.com/releases/2008/06/080619142124.htm Bright Chunks At Phoenix Lander's Mars Site Must Have Been Ice- June 20, 2008 Dice-size crumbs of bright material have vanished from inside a trench where they were photographed by NASA's Phoenix Mars Lander four days ago, convincing scientists that the material was frozen water that vaporized after digging exposed it.http://www.sciencedaily.com/releases/2008/06/080619221234.htm Slimmer Milky Way Galaxy Revealed By New Measurements- June 20, 2008 The Milky Way Galaxy has lost weight. A lot of weight. About a trillion Suns' worth, according to an international team of scientists from the Sloan Digital Sky Survey (SDSS-II), whose discovery has broad implications for our understanding of the Milky Way.http://www.sciencedaily.com/releases/2008/06/080618160914.htm Protecting Muscles Of Astronauts- June 19, 2008 As astronaut Garrett Reisman adjusts to Earth's gravity after three months in space, a University of Kentucky physiologist is continuing his tests on a 50-year-old drug used for liver treatments as a means of helping astronauts perform their work during space walks.http://www.sciencedaily.com/releases/2008/06/080619113055.htm Black Holes Have Simple Feeding Habits- June 18, 2008 The biggest black holes may feed just like the smallest ones, according to data from NASA's Chandra X-ray Observatory and ground-based telescopes. This discovery supports the implication of Einstein's relativity theory that black holes of all sizes have similar properties, and will be useful for predicting the properties of a conjectured new class of black holes.http://www.sciencedaily.com/releases/2008/06/080618133708.htm Phoenix Makes First Trench In Science Preserve- June 18, 2008 NASA's Phoenix Mars Lander began digging in an area called "Wonderland" early Tuesday, taking its first scoop of soil from a polygonal surface feature within the "national park" region that mission scientists have been preserving for science.http://www.sciencedaily.com/releases/2008/06/080617210034.htm NASA Mars Lander To Dig; Team Probes Flash Memory- June 18, 2008 NASA's Phoenix Mars Mission generated an unusually high volume of spacecraft housekeeping data on Tuesday causing the loss of some non-critical science data. Phoenix engineers are analyzing why this anomaly occurred. The science team is planning spacecraft activities for Thursday that will not rely on Phoenix storing science data overnight but will make use of multiple communication relays to gain extra data quantity.http://www.sciencedaily.com/releases/2008/06/080618220512.htm Phoenix Lander Bakes Sample, Arm Digs Deeper- June 18, 2008 One of the ovens on NASA's Phoenix Mars Lander continued baking its first sample of Martian soil over the weekend, while the Robotic Arm dug deeper into the soil to learn more about white material first revealed on June 3.http://www.sciencedaily.com/releases/2008/06/080617205826.htm |
