New Purdue Facility Aims To Improve NASA Moon Rocket Engine
West Lafayette IN (SPX) Mar 13, 2008Purdue University engineers are conducting experiments using a new hydrogen facility to help NASA create designs to improve the cooling efficiency and performance of the J-2X rocket engine, critical for future missions to Mars and the moon. More efficient cooling improves performance and reduces the need for costly overhauls, said William Anderson, an associate professor in Purdue's School of ... more HiRISE Discovers A Possibly Once-Habitable Ancient Mars Lake 
Tucson AZ (SPX) Mar 07, 2008Scientists studying images from The University of Arizona-led High Resolution Imaging Experiment camera on NASA's Mars Reconnaissance Orbiter have discovered never-before-seen impact "megabreccia" and a possibly once-habitable ancient lake on Mars at a place called Holden crater. The megabreccia is topped by layers of fine sediments that formed in what apparently was a long-lived, calm lake ... more Europe Ready To Launch World's Latest Space Freighter 
Paris (AFP) March 6, 2008The most advanced robot freighter in space history is due for its maiden launch this weekend, crowning Europe's involvement in the troubled International Space Station. If all goes well, a beefed-up Ariane 5 rocket will blast off from French Guiana at 0339 GMT on Sunday, taking aloft a cylindrical craft the size of a London double-decker bus that will play a unique dual role of cargo ... more Mars And Venus Are Surprisingly Similar 
Paris, France (ESA) Mar 06, 2008Using two ESA spacecraft, planetary scientists are watching the atmospheres of Mars and Venus being stripped away into space. The simultaneous observations by Mars Express and Venus Express give scientists the data they need to investigate the evolution of the two planets' atmospheres. Scientists call this work comparative planetology. Mars Express and Venus Express are so good at it becau ... more Mechdyne Enables Virtual Reality Of Mission To Mars 
Marshalltown IA (SPX) Mar 06, 2008Mechdyne has announced that it has installed an immersive CAVE display system as the focal point of the new Fossett Laboratory for Virtual Planetary Exploration at Washington University St. Louis (WUSTL). As a teaching and research facility of the Department of Earth and Planetary Sciences, the Laboratory will provide 3D imaging capability for visualization of data collected by national and inte ... more |

Pasadena CA (SPX) Mar 04, 2008A NASA spacecraft in orbit around Mars has taken the first ever image of active avalanches near the Red Planet's north pole. The image shows tan clouds billowing away from the foot of a towering slope, where ice and dust have just cascaded down. The High Resolution Imaging Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter took the photograph Feb. 19. It is one of approximately 2,400 ... more Liquid Water Found Flowing On Mars - Not Yet 
Tuscon AZ (SPX) Mar 04, 2008Liquid water has not been found on the Martian surface within the last decade after all, according to new research. The finding casts doubt on the 2006 report that the bright spots in some Martian gullies indicate that liquid water flowed down those gullies sometime since 1999. "It rules out pure liquid water," said lead author Jon D. Pelletier of The University of Arizona in Tucson. ... more Study casts doubt on Mars water find 
Tucson (UPI) Mar 03, 2008A U.S. scientist said high resolution images raise doubt that liquid water has been found on the surface of Mars. Jon D. Pelletier of The University of Arizona in Tucson said topographic data from the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter shows that a bright streak in a gully on the side of a crater is probably not water. ... more Opportunity Proceeds With Caution On Sandy Slopes 
Pasadena CA (SPX) Feb 29, 2008After recovering from a stall in Joint 1, which controls the compass orientation of the shoulder on the rover's robotic arm, Opportunity is proceeding carefully to its next target, an exposure of layered rocks known as "Gilbert." Opportunity ran the usual diagnostic tests for this sort of fault, which occurred while the rover was studying a rock target known as "Buckland," and successfully place ... more |

Washington DC (SPX) Feb 27, 2008Modelling of the Earth's atmosphere has acquired economic importance due to its use in the prediction of ozone depletion and in measuring the impact of global warming. Now, researchers, writing in the online open access journal PMC Physics B have found that the rate at which electrons lose energy to carbon monoxide is greater than that to carbon dioxide at higher levels in the atmospheres of ... more Unique Martian Formation Reproduced, Reveals Brief Bursts Of Water 
Blacksburg VA (SPX) Feb 22, 2008Researchers from the United States and the Netherlands report that several formations on Mars indicate incidents of rapid release of water from the planet's interior. Mars has many basins that contain formations that look like fans. A few of these fans, only about 10, have steps down into the basin. Since scientists first reported this feature three years ago, there has been no clear conse ... more US space shuttle Atlantis returns home 
Cape Canaveral, Florida (AFP) Feb 20, 2008The shuttle Atlantis safely landed in Florida Wednesday, completing a successful mission to install Europe's first space laboratory. Atlantis touched down at the seaside Kennedy Space Center in Cape Canaveral, bringing home seven astronauts following a 13-day mission to deliver the Columbus lab to the orbiting International Space Station. The shuttle's return also cleared the skies for ... more Mars study shows oceans of water bubbled up from below 
Paris (AFP) Feb 20, 2008Fan-shaped deltas at the edge of huge basins scattered across Mars were probably formed by a titanic influx of water, gushing from the bowels of the Red Planet, according to study released Wednesday. The origin and morphology of the deltas, studded with curious step-like terraces, have perplexed scientists since they were first observed three years ago. Today the surface of Mars is bone dry ... more
