Solar Wind Rips Up Martian Atmosphere
Huntsville AL (SPX) Nov 24, 2008Researchers have found new evidence that the atmosphere of Mars is being stripped away by solar wind. It's not a gently continuous erosion, but rather a ripping process in which chunks of Martian air detach themselves from the planet and tumble into deep space. This surprising mechanism could help solve a longstanding mystery about the Red Planet. "It helps explain why Mars has so little a ... more Mars Express Observes Aurorae On The Red Planet 
Paris, France (SPX) Nov 24, 2008Scientists using ESA's Mars Express have produced the first crude map of aurorae on Mars. These displays of ultraviolet light appear to be located close to the residual magnetic fields generated by Mars's crustal rocks. They highlight a number of mysteries about the way Mars interacts with electrically charged particles originating from the Sun. The aurorae on Mars were discovered in 2004 ... more Dawn Glides Into New Year 
Pasadena CA (SPX) Nov 24, 2008JPL's Dawn spacecraft shut down its ion propulsion system as scheduled. The spacecraft is now gliding toward a Mars flyby in February of next year. "Dawn has completed the thrusting it needs to use Mars for a gravity assist to help get us to Vesta," said Marc Rayman, Dawn's chief engineer, of NASA's Jet Propulsion Laboratory, Pasadena, Calif. "Dawn will now coast in its orbit around ... more European to become commander of space station in 2009 
Paris (AFP) Nov 20, 2008The International Space Station (ISS) next year will be commanded for the first time by a European, the European Space Agency (ESA) announced here on Friday. Belgian astronaut Frank de Winne will be taken aloft next May aboard a Russian Soyuz spacecraft, a`long with Russian cosmonaut Roman Romanenko and Canadia's Robert Thirsk, taking the ISS's full-time crew from three to six, ESA said in a ... more NASA Spacecraft Detects Buried Glaciers On Mars 
Pasadena CA (SPX) Nov 21, 2008NASA's Mars Reconnaissance Orbiter has revealed vast Martian glaciers of water ice under protective blankets of rocky debris at much lower latitudes than any ice previously identified on the Red Planet. Scientists analyzed data from the spacecraft's ground-penetrating radar and report in the Nov. 21 issue of the journal Science that buried glaciers extend for dozens of miles from the edges ... more |

Pasadena CA (SPX) Nov 20, 2008Four intriguing places on Mars have risen to the final round as NASA selects a landing site for its next Mars mission, the Mars Science Laboratory. The agency had a wider range of possible landing sites to choose from than for any previous mission, thanks to the Mars Science Laboratory's advanced technologies, and the highly capable orbiters helping this mission identify scientifically ... more Students Invited To Name New Mars Rover 
Washington DC (SPX) Nov 19, 2008NASA is looking for the right stuff, or in this case, the right name for the next Mars rover. NASA, in cooperation with Walt Disney Studios Motion Pictures' movie WALL-E from Pixar Animation Studios, will conduct a naming contest for its car-sized Mars Science Laboratory rover that is scheduled for launch in 2009. The contest begins Tuesday, Nov. 18, and is open to students 5 to 18 years ... more Gamma-Ray Evidence Suggests Ancient Mars Had Oceans 
Tucson AZ (SPX) Nov 18, 2008An international team of scientists who analyzed data from the Gamma Ray Spectrometer onboard NASA's Mars Odyssey reports new evidence for the controversial idea that oceans once covered about a third of ancient Mars. "We compared Gamma Ray Spectrometer data on potassium, thorium and iron above and below a shoreline believed to mark an ancient ocean that covered a third of Mars' surface ... more Carbonate Conundrum 
Moffett Field CA (SPX) Nov 18, 2008Mars is good at keeping its secrets. As a case in point, consider the discovery by NASA's Phoenix lander of carbonates in the planet's northern polar plains. The goal of the Phoenix mission was to understand the historic role of water in the frozen martian north, and to assess the region's habitability. Carbonates form in the presence of water. So one might think that their discovery is ... more |

Washington DC (SPX) Nov 14, 2008The Planetary Society outlined Thursday a vigorous new approach to space exploration for the consideration of the new U.S. Administration and Congress. "Beyond the Moon: A New Roadmap for Human Space Exploration in the 21st Century" calls for the United States to create - in cooperation with international partners - a space program that is as inspiring as it is sustainable in the world's current ... more Space Fantasy 2009 
Gerroa NSW (SPX) Nov 14, 2008Are we heading into 1999 or 2009. Either way it's time for another space fantasy - this time from The Planetary Society who are advising the incoming US Administration that the Moon is the wrong destination goal and that Mars is actually the correct destination. Problem is, NASA has Buckley's chance of reaching the moon anytime in the next decade let alone Mars in the next 25 years. ... more Controllers Cheer As Data Arrive from NASA's Spirit Rover 
Pasadena CA (SPX) Nov 14, 2008NASA's Mars Exploration Rover Spirit communicated via the Mars Odyssey orbiter today right at the time when ground controllers had told it to, prompting shouts of "She's talking!" among the rover team at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "This means Spirit has not gone into a fault condition and is still being controlled by sequences we send from the ground," said John ... more Indian Probe Impacts Moon 
Bangalore, India (AFP) Nov 14, 2008An Indian probe landed on the moon on Friday, the Indian Space Research Organisation announced, in a milestone for the country's 45-year-old space programme. The probe touched down on the moon at 8:34pm (1504 GMT), 25 minutes after it was ejected from an unmanned spacecraft orbiting the moon, spokesman S. Satish said. "During its descent from Chandrayaan-1 an onboard video camera transmi ... more
