Sulfur Dioxide May Have Helped Maintain A Warm Early Mars
Cambridge MA (SPX) Dec 21, 2007Sulfur 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 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. The Science paper's a ... more Opportunity Maneuvers Around Steeper Slopes In Victoria Crater 
Pasadena CA (SPX) Dec 21, 2007Opportunity is now in the process of driving to the third band of light-colored rocks that circumvent "Victoria Crater" beneath the rim. Scientists had initially planned to have the rover head directly downhill to a rock target nicknamed "Ronov," within the band known as "Lyell." They selected an alternate rock exposure, dubbed "Newell," when engineers determined that the original drive r ... more Spirit Update: Soon To Find Winter Resting Place 
Pasadena CA (SPX) Dec 20, 2007To 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, 2007Russia 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 The Closest Approach Of Mars In 2007 
Pasadena CA (SPX) Dec 19, 2007Now playing online -- a new Martian movie showing the planet rotating. The movie was made from four images taken by the Hubble Space Telescope's Wide Field Planetary Camera 2, built and designed by JPL. The images were taken within 36 hours of today's closest approach to Earth by Mars. The camera captured the views when Mars was just 88 million kilometers (55 million miles) away. Mars and ... more |

Bangalore, India (AFP) Dec 16, 2007India 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, 2007Scrutiny 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, 2007How 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 Building Blocks Of Life Formed On Mars 
Washington DC (SPX) Dec 12, 2007Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists at the Carnegie Institution's Geophysical Laboratory have shown for the first time that building blocks of life formed on Mars early in its history. Previously, scientists have thought that organic mater ... more |

Columbus OH (SPX) Dec 11, 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 International Group Plans Strategy For Mars Sample Return Mission 
Washington DC (SPX) Dec 11, 2007NASA and an international team are developing plans and seeking recommendations to launch the first Mars mission to bring soil samples back to Earth. The ability to study soil from Mars here on Earth will contribute significantly to answering questions about the possibility of life on the Red Planet. Returned samples also will increase understanding of the useful or harmful properties of Martian ... more Mars Rover Investigates Signs Of Steamy Martian Past 
San Francisco CA (SPX) Dec 11, 2007Researchers using NASA's twin Mars rovers are sorting out two possible origins for one of Spirit's most important discoveries, while also getting Spirit to a favorable spot for surviving the next Martian winter. The puzzle is what produced a patch of nearly pure silica -- the main ingredient of window glass -- that Spirit found last May. It could have come from either a hot-spring environment o ... more Opportunity Grinds Into Rock In Victoria Crater 
Pasadena CA (JPL) Dec 11, 2007Opportunity spent part of the past week carefully grinding a hole into the surface of a light-colored ring of rock inside "Victoria Crater" known as "Smith," despite the previous loss of encoders that enabled two of the motors of the rock abrasion tool to operate under control of the tool's flight software. The endeavor was successful, with the rover grinding to a depth of about 1 millimet ... more
