Mars Express Creates First Global Map Of Martian Ionosphere
Paris, France (ESA) Nov 19, 2007With ESA's Mars Express, scientists continue to gain new insight into the mysterious Martian environment. Some of the most exciting results are being sent back by the MARSIS (Mars Advanced Radar for Subsurface and Ionospheric Sounding) experiment. MARSIS transmits low frequency radio waves towards the planet's surface and records the echoes of the different layers. Although Mars is sometim ... more Planets Forming In Pleiades Star Cluster 
Los Angeles CA (SPX) Nov 16, 2007Rocky terrestrial planets, perhaps like Earth, Mars or Venus, appear to be forming or to have recently formed around a star in the Pleiades ("seven sisters") star cluster, the result of "monster collisions" of planets or planetary embryos. Astronomers using the Gemini Observatory in Hawaii and the Spitzer Space Telescope report their findings in an upcoming issue of the Astrophysical Journal, th ... more Rover Finds Way To Brush Rock Surfaces Despite Setbacks 
Pasadena CA (JPL) Nov 15, 2007Opportunity is still parked in front of the rock layer known as "Smith" inside Victoria Crater. The rover has now lost two encoders that operate motors on the rock abrasion tool during the grinding and brushing of surfaces. Science team members and engineers have been working in test beds and computer sequencing rooms to devise creative ways of using the rock abrasion tool without the grind and ... more Europe's comet-chasing probe completes key flyby 
Paris (AFP) Nov 14, 2007A billion-euro (1.45-billion-dollar) European scout craft completed a crucial fly-by of Earth to pick up speed on its 10-year mission to rendezvous with a distant comet, the European Space Agency (ESA) said on Wednesday. "An important milestone has just been accomplished," the Paris-based agency said after the Rosetta probe raced over the Pacific Ocean southwest of Chile late Tuesday at 45,0 ... more Opportunity's Rock Abrasion Tool Shows Anomalous Behavior 
Pasadena CA (SPX) Nov 14, 2007During the past week, Opportunity continued to investigate the rock layer known as "Smith," the second of three "bathtub-ring" layers of rock inside "Victoria Crater." The vehicle is mostly healthy, except for a recent anomaly involving the rock abrasion tool. Planned operations with the rock abrasion tool failed on Martian day, or sol, 1334 (Oct. 25, 2007), during both the calibration and ... more |

Washington (AFP) Nov 8, 2007NASA penny-pinching risks exposing humankind to a planetary catastrophe if a big enough asteroid evades detection and slams into Earth, US lawmakers warned Thursday. But the US space agency said the chances of a new "Near-Earth Object" (NEO) like the one that wiped out the dinosaurs were too remote to divert scarce resources. Scott Pace, head of program analysis and evaluation at NASA, s ... more ISS astronauts prepare Harmony module for permanent docking 
Washington (AFP) Nov 9, 2007A US and Russian astronaut on the International Space Station on Friday went on a seven-hour spacewalk to prepare the recently delivered Harmony module for its permanent docking point on the ISS, NASA said. Commander Peggy Whitson and Flight Engineer Yuri Malenchenko "spent Friday morning disconnecting and stowing cables, removing a light ... and taking a cover off the Harmony node's Common ... more Shuttle returns safely to Earth after complex mission 
Cape Canaveral, Florida (AFP) Nov 7, 2007The US Space Shuttle Discovery landed back on Earth on Wednesday successfully ending one of the trickiest and riskiest missions ever to the International Space Station. Under clear blue skies, the shuttle, with its seven-strong crew, landed on schedule at 13:01 (1801 GMT) at the Kennedy Space Center in Florida after a mission lasting 15 days, two hours and 23 minutes. "Congratulations on ... more Opportunity's Second Martian Birthday At Cape Verde 
Pasadena CA (SPX) Nov 08, 2007A promontory nicknamed "Cape Verde" can be seen jutting out from the walls of Victoria Crater in this approximate true-color picture taken by the panoramic camera on NASA's Mars Exploration Rover Opportunity. The rover took this picture on martian day, or sol, 1329 (Oct. 20, 2007), more than a month after it began descending down the crater walls - and just 9 sols shy of its second Martian birth ... more |

Daytona Beach FL (SPX) Nov 05, 2007Researchers, teachers and students will have access to weightless and variable-gravity conditions under a new agreement between Embry-Riddle Aeronautical University and Zero Gravity Corp. (Zero-G). Embry-Riddle and Zero-G will work together to integrate weightless flights and space science workshops for K-12 teachers, develop experiment programs for high school and college students, and expand m ... more Opportunity Studies Bathtub Ring In Victoria 
Pasadena CA (SPX) Nov 05, 2007Opportunity is healthy, with energy levels ranging from about 450 watt-hours to 475 watt-hours (100 watt-hours is the amount of electricity needed to light a 100-watt bulb for one hour). Recently, Opportunity was temporarily unable to send scientific data to Earth because the Odyssey orbiter experienced a computer crash and went into "safing" mode. While in safing mode, the spacecraft shut ... more Mars Express Probes The Red Planet's Most Unusual Deposits 
Paris, France (ESA) Nov 05, 2007The radar system on ESA's Mars Express has uncovered new details about some of the most mysterious deposits on Mars: The Medusae Fossae Formation. It has given the first direct measurement of the depth and electrical properties of these materials, providing new clues about their origin. The Medusae Fossae Formation (MFF) are unique deposits on Mars. They are also an enigma. Found near the ... more Mars Express Probes Red Planet's Unusual Deposits
