How The Atmospheres Of Mars And Venus Are Affected By Carbon Monoxide
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 Spirit Inches Downward Into Final Winter Perch 
Pasadena CA (JPL) Feb 20, 2008Spirit is tiptoeing ever so carefully down the north edge of the elevated volcanic plateau known as "Home Plate." Having completed a 4-cm drive on sol 1463, the rover's current northerly tilt is 27.1 degrees. Spirit's handlers plan to have the rover drive another 4 centimeters on sol 1464. Spirit should be at its final winter perch by the end of next week, following a few more 4-cm drives. Given recent progress, Spirit may achieve a northerly, Sun-facing tilt of 30 degrees, higher than originally anticipated. ... more |

Paris (ESA) Feb 5, 2008The European Space Agency on Tuesday unveiled images of Mars in three dimensions to help understand the Red Planet's unique topography. The Digital Terrain Model pictures have been built up thanks to a high-resolution stereoscopic camera aboard Mars Express, the ESA orbiter. Mars has extraordinary canyons and plains as well as the highest known mountain in the Solar System ... more Countdown begins for US-Europe space mission 
Washington (AFP) Feb 5, 2008The crew of the US shuttle Atlantis readied Tuesday for this week's delayed mission to deliver a European space laboratory to the orbiting International Space Station. Lift-off, originally scheduled for December, now is set for Thursday after a two-month delay, while engineers got to the bottom of electrical faults with fuel gauges on the shuttle's external fuel tank. "Atlantis is ready ... more NASA Budget Request Strong On Earth Weak On Mars 
Pasadena CA (SPX) Feb 06, 2008Two new Earth-observing satellites, a "flagship" mission to the outer planets, and several small lunar missions are among the highlights of the Administration's budget request for NASA for fiscal year 2009. At $17.6 billion the proposal represents a 1.8% increase over NASA's actual budget for 2008, and $4.44 billion, or just over a quarter of the total, is slated towards NASA's science missions. ... more Bush sets out tiny 2.9 percent rise in space budget 
Washington (AFP) Feb 4, 2008President George W. Bush Monday set out a modest 2.9 percent rise in funding for the US space agency, just as NASA is racing to finish the International Space Station in 2010. The funds were contained in Bush's proposed 3.1 trillion dollar budget for the fiscal year 2009, which earmarked a total 17.61 billion dollars for National Aeronautics and Space Administration projects in the coming ... more |

Paris, France (ESA) Jan 28, 2008The High Resolution Stereo Camera (HRSC) on board ESA's Mars Express has returned striking scenes of the Terby crater on Mars. The region is of great scientific interest as it holds information on the role of water in the history of the planet. The image data was obtained on 13 April 2007 during orbit 4199, with a ground resolution of approximately 13 m/pixel. The Sun illuminates the scene ... more HiRISE Camera Details Dynamic Wind Action On Mars 
Phoenix AZ (SPX) Jan 24, 2008Mars has an ethereal, tenuous atmosphere at less than 1 percent the surface pressure of Earth, so scientists working on The University of Arizona's High Resolution Imaging Experiment, or HiRISE, are challenged to explain the complex, wind-sculpted landforms they're now seeing in unprecedented detail. The HiRISE camera on NASA's Mars Reconnaissance Orbiter, the most powerful camera to orbit ... more Asteroid to give Earth a close shave next week 
Paris (AFP) Jan 23, 2008A huge asteroid will zoom past Earth next week at such a close distance that amateur astronomers should be able to spot it, specialists said on Wednesday. Measuring between 150 and 600 metres (yards) across, asteroid 2007 TU24 would inflict devastating regional damage were it to hit Earth, but there is no risk of any collision, they said. It will fly by on Tuesday, being around 534,000 k ... more Ice Clouds Put Mars In The Shade 
Paris, France (SPX) Jan 17, 2008Until now, Mars has generally been regarded as a desert world, where a visiting astronaut would be surprised to see clouds scudding across the orange sky. However, new results show that the arid planet possesses high-level clouds that are sufficiently dense to cast a shadow on the surface. The results were obtained by the OMEGA Visible and Infrared Mineralogical Mapping Spectrometer instru ... more
