Traces Of The Martian Past In The Terby Crater
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 Scientists examine effects of wind on Mars 
Pasadena, Calif. (UPI) Jan 16, 2007 U.S. scientists have obtained high-resolution images of Mars' wind-driven sand dunes and ridges that might lead to a better understanding of the planet. The pictures were taken by the High Resolution Imaging Science Experiment camera on the Mars Reconnaissance Orbiter. The camera is capable of imaging features less than half a meter -- about 20 inches in size. The scientists said ... more |

Moscow (AFP) Jan 7, 2008Russia plans to participate in a European mission to investigate Jupiter's moon Europa and search for simple life forms, the Interfax news agency reported on Monday, quoting a senior researcher. The head of the Space Research Institute, Lev Zelyony, said a project to explore the giant gaseous planet Jupiter would shortly be included in the programme of the European Space Agency (ESA) for the ... more Spirit's West Valley Panorama 
Pasadena CA (SPX) Jan 04, 2008NASA'S Mars Exploration Rover Spirit captured this westward view from atop a low plateau where Sprit spent the closing months of 2007. After several months near the base of the plateau called "Home Plate" in the inner basin of the Columbia Hills range inside Gusev Crater, Spirit climbed onto the eastern edge of the plateau during the rover's 1,306th Martian day, or sol, (Sept. 5, 2007). It ... more New Observations Slightly Decrease Mars Impact Probability 
Pasadena CA (JPL) Jan 03, 2008Additional position observations for asteroid 2007 WD5 taken on December 29 through January 2 have been used to improve the accuracy of the asteroid's orbit. As a result, the range of possible paths past Mars has narrowed by a factor of 3 and the most likely path has moved a little farther away from the planet, causing the Mars impact probability to decrease slightly to 3.6% (about one cha ... more Mars Rovers Find Evidence Of Habitable Niche As Perilous Third Winter Approaches 
Cornell NY (SPX) Dec 31, 2007Inch by power-conserving inch, drivers on Earth have moved the Mars rover Spirit to a spot where it has its best chance at surviving a third Martian winter -- and where it will celebrate its fourth anniversary (in Earth years) since bouncing down on Mars for a projected 90-day mission in January 2004. Meanwhile, researchers are considering the implications of what Cornell's Steve Squyres, ... more |

Cambridge, MA (SPX) Dec 24, 2007Harvard University Sulfur dioxide (SO2) may have played a key role in the climate and geochemistry of early Mars, geoscientists at Harvard University and the Massachusetts Institute of Technology (MIT) suggest in the Dec. 21 issue of the journal Science. Their hypothesis may resolve longstanding questions about evidence that the climate of the Red Planet was once much warmer than it is today. ... more Catalina Sky Survey Rocks Mars With New Asteroid Discovery 
Tucson AZ (SPX) Dec 24, 2007An asteroid discovered by The University of Arizona's Catalina Sky Survey has a one-in-75 chance of hitting Mars Jan. 30, scientists tracking it say. Catalina Sky Survey team member Andrea Boattini discovered the asteroid, designated 2007 WD5, with UA's Mount Lemmon 60-inch telescope in the Santa Catalina Mountains north of Tucson on Nov. 20. At the time, the asteroid was at 20th magnitude ... more Astronomers Monitor Asteroid To Pass Near Mars 
Pasadena CA (SPX) Dec 24, 2007Astronomers funded by NASA are monitoring the trajectory of an asteroid estimated to be 50 meters (164 feet) wide that is expected to cross Mars' orbital path early next year. Observations provided by the astronomers and analyzed by NASA's Near-Earth Object Office at the Jet Propulsion Laboratory in Pasadena, Calif., indicate the object may pass within 30,000 miles of Mars at about 6 a.m. EST (3 ... more In Search For Water On Mars Via Clues From Antarctica 
Columbus OH (SPX) Dec 24, 2007Scientists have gathered more evidence that suggests flowing water on Mars -- by comparing images of the red planet to an otherworldly landscape on Earth. In recent years, scientists have examined images of several sites on Mars where water appears to have flowed to the surface and left behind a trail of sediment. Those sites closely resemble places where water flows today in the McMurdo Dry Val ... more
