Dust Storm Cuts Energy Supply Of NASA Mars Rover Spirit
Pasadena CA (SPX) Nov 13, 2008A dust storm on Mars has cut into the amount of sunlight reaching the solar array on NASA's Mars Exploration Rover Spirit, leaving the rover in a vulnerable state. Spirit's solar array produced only 89 watt hours of energy during the rover's 1,725th Martian day, which ended on Nov. 9. This is the lowest output by either Spirit or its twin, Opportunity, in their nearly five years on Mars ... more Phoenix probe mission on Mars ends: NASA 
Washington (AFP) Nov 10, 2008NASA scientists said Monday the Phoenix Mars lander has gone silent because of a lack of sunlight needed to power its batteries, after a five-month mission that produced a mother lode of scientific data from the red planet. After operating two months longer than scientists had initially planned, the probe ceased all communications with Earth starting on November 2, said Barry Goldstein ... more Shortlist for Martian masochists 
Paris (AFP) Nov 10, 2008European scientists said they had selected a shortlist of eight men Monday willing to take part in a 105-day isolation experiment to further knowledge about the stress of a manned trip to Mars. Six of the eight candidates will be chosen to live, eat, sleep and work inside a sealed laboratory in Moscow that will simulate a Martian mission, the European Space Agency (ESA) said. Their stay ... more Spirit Begins Driving Uphill 
Pasadena CA (SPX) Nov 11, 2008With the Sun moving higher in the sky, Spirit's solar panels must move in the same direction to maximize their exposure to sunlight. To achieve optimal solar input, the panels still must tilt to the north, but not as steeply as before. To change the tilt, rover drivers have begun moving Spirit back upslope toward the top of "Home Plate." Their goal is to reduce the rover's northerly tilt ... more Farewell, Victoria, And On To Endeavour 
Pasadena CA (SPX) Nov 11, 2008Opportunity took the last images of "Victoria Crater" before beginning the journey to Endeavour Crater. The final focus of the rover's cameras was a cliff at the edge of Victoria nicknamed "Cape Victory." After spending more than two years investigating this spectacular crater, Opportunity took parting images as Victoria disappeared into the distance. The rover first arrived at the ... more |

Paris (AFP) Nov 4, 2008Scientists believe they have found a way of protecting astronauts from a dangerous source of space radiation, thus lifting a major doubt clouding the dream to send humans to Mars. Their breakthrough takes forward ideas born in the golden age of science fiction, including a proton shield used in the TV show "Star Trek," says one of the researchers. Space weather is one of the greatest cha ... more New Spaceship Force Field Makes Mars Trip Possible 
London, UK (SPX) Nov 05, 2008According to the international space agencies, "Space Weather" is the single greatest obstacle to deep space travel. Radiation from the sun and cosmic rays pose a deadly threat to astronauts in space. New research, out today, Tuesday, November 4, published in IOP Publishing's Plasma Physics and Controlled Fusion, shows how knowledge gained from the pursuit of nuclear fusion research may r ... more NASA Hearing Daily From Weak Phoenix Mars Lander 
Pasadena CA (SPX) Nov 05, 2008NASA's Phoenix Mars Lander has communicated with controllers daily since Oct. 30 through relays to Mars orbiters. Information received over the weekend indicates Phoenix is running out of power each afternoon or evening but reawakening after its solar arrays catch morning sunlight. The fraction of each day with sun above the horizon is declining at the Martian arctic landing site. Dust rai ... more NASA: Phoenix weak and getting weaker 
Pasadena, Calif. (UPI) Nov 4, 2008 The U.S. space agency says its Phoenix Mars Lander has communicated with controllers daily since Sunday, but it is becoming weaker. The National Aeronautics and Space Administration said data received so far indicates Phoenix is running out of power each afternoon or evening, only reawakening after its solar arrays catch morning sunlight. But scientists said the fraction of each ... more |

Tuscon AZ (SPX) Oct 30, 2008One of the most fun and fascinating aspects of space exploration is discovering geological processes and terrain different from those found on our home planet, says Matt Balme, who is leading a team that's decoding Martian mystery landscapes known as Transverse Aeolian Ridges or TARs. Balme, a research scientist with the Tucson-based Planetary Science Institute, says TARs have no exact ... more US space probe completes successful Mercury fly-pass 
Washington (AFP) Oct 29, 2008The US space probe MESSENGER made its second successful fly-by of the year of the planet Mercury on October 6, revealing like never before 30 percent of the solar system's smallest planet, scientists said Thursday. MESSENGER (MErcury Surface, Space ENvironment, GEochemistry and Ranging) soared past the innermost planet's equator at an altitude of 201 kilometers at a speed of ... more NASA's Phoenix Mission Faces Survival Challenges
Pasadena CA (SPX) Oct 29, 2008In a race against time and the elements, engineers with NASA's Phoenix Mars Lander mission hope to extend the lander's survival by gradually shutting down some of its instruments and heaters, starting today. Originally scheduled to last 90 days, Phoenix has completed a fifth month of exploration in the Martian arctic. As expected, with the Martian northern hemisphere shifting from summer ... more NASA Orbiter Reveals Details Of A Wetter Mars 
Pasadena CA (SPX) Oct 29, 2008NASA's Mars Reconnaissance Orbiter has observed a new category of minerals spread across large regions of Mars. This discovery suggests that liquid water remained on the planet's surface a billion years later than scientists believed, and it played an important role in shaping the planet's surface and possibly hosting life. Researchers examining data from the orbiter's Compact Reconnaissa ... more
