How Mars Could Have Been Warm And Wet But Limestone-Free
Cambridge MA (SPX) Dec 24, 2007
Planetary scientists have puzzled for years over an apparent contradiction on Mars. Abundant evidence points to an early warm, wet climate on the red planet, but there's no sign of the widespread carbonate rocks, such as limestone, that should have formed in such a climate. Now, a detailed analysis in the Dec. 21 issue of Science by MIT's Maria T. Zuber and Itay Halevy and Daniel P. Schrag of Ha ... read more

    NASA Delays Mars Scout Mission To 2013
    Washington DC (SPX) Dec 24, 2007
    NASA has decided that the next mission in the Mars Scout program, originally planned for launch in 2011, is now targeted for launch in 2013. The schedule slip is because of an organizational conflict of interest that was discovered in one of the mission proposal team's Phase A Concept Study. This was the shortest delay for the mission possible because opportunities to send spacecraft to Mars occ ... more

    Sulfur Dioxide May Have Helped Maintain A Warm Early Mars
    Cambridge, MA (SPX) Dec 24, 2007
    Harvard 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, 2007
    An 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, 2007
    Astronomers 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

    Global Map Reveals Mineral Distribution On Mars
    Laurel, MD (SPX) Dec 24, 2007
    Scientists are getting a clearer image of mineral distribution on the surface of Mars, thanks to the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), one of six science instruments on NASA's Mars Reconnaissance Orbiter, currently circling the planet. More than 200 just-released "spectral maps" reveal the distribution of various minerals on the surface of Mars -- the first installmen ... more

    Asteroid could hit Mars next month: NASA
    Los Angeles (AFP) Dec 21, 2007
    An asteroid hurtling towards Mars has a one in 75 chance of chance of scoring a direct hit on the red planet next month, NASA experts said in a statement Friday. The US space agency's Near Earth Object Program (NEOP) revealed that the asteroid's exact course was difficult to predict, but said it could slam into Mars on January 30, leaving a crater measuring an estimated 1 kilometer across. ... more

    Spirit Update: Soon To Find Winter Resting Place
    Pasadena CA (SPX) Dec 20, 2007
    To make the most of waning sunlight during the approach of Martian winter, Spirit's handlers have returned to "Mars time." This means their working hours coincide with the Martian day, as they did for the first three months after the rover landed on the red planet. Because a Martian day is about 40 minutes longer than an Earth day, Mars time can coincide with all hours of the day and night on ... more

    Russia To Launch Space Base For Missions To Moon And Mars After 2020
    Moscow (RIA Novosti) Dec 19, 2007
    Russia plans to deploy an orbiting base for manned and unmanned missions to the Moon and Mars after 2020, the head of the space agency said on Tuesday. "After 2020, Russia plans to create and put into orbit a near-Earth experimental manned complex to ensure transport operations to the Moon and Mars," Anatoly Perminov said. He also said Russia has tentative plans for manned missions to Mars ... more

    Spirit Scouts Home Plate For Safe Haven
    Pasadena CA (JPL) Dec 17, 2007
    Spirit has arrived at the north edge of "Home Plate." The rover will spend the next few Martian days, or sols, scouting the edge of Home Plate and acquiring images of the slopes to determine the best site for "Winter Haven 3," where Spirit will try to survive another season of minimal sunlight. Once the team selects a site, Spirit will drive down the north-facing edge of Home Plate and maneuve ... more

    India installs antennas for planned moon mission: official
    Bangalore, India (AFP) Dec 16, 2007
    India has installed a pair of giant antennas to monitor a planned robotic mission to the moon next year, making it one of a few nations with deep space tracking ability, officials said. The deep space network at Byalalu, 45 kilometres (30 miles) from Bangalore, will keep track of the Chandrayaan-1 lunar mission and provide command support during its two-year orbit around the moon, India's sp ... more

    Mars Orbiter Examines Lace And Lizard Skin Terrain
    San Francisco CA (SPX) Dec 13, 2007
    Scrutiny by NASA's newest Mars orbiter is helping scientists learn the stories of some of the weirdest landscapes on Mars, as well as more familiar-looking parts of the Red Planet. One type of landscape near Mars' south pole is called "cryptic terrain" because it once defied explanation, but new observations bolster and refine recent interpretations of how springtime outbursts of carbon-di ... more

    Lighting Up The Lunar Night With Fuel Cells
    Cleveland OH (SPX) Dec 13, 2007
    How do you survive in a remote, mountainous region that has no water or wind and sometimes goes without sunlight for weeks? This is not the premise for a survivalist reality show; it's a question NASA must answer before sending humans to live and work on the moon. Within the next twenty years, people again will explore the vast lunar terrain. This time, we're going to build a permanent out ... more
