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 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 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 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 NASA marks 10th ISS anniversary with spacewalk 
Washington (AFP) Nov 20, 2008Astronauts from the shuttle Endeavour marked the 10th anniversary of the International Space Station Thursday by exiting the station for the second of four spacewalks. The US space agency NASA said astronauts Heide Stefanyshyn-Piper and Shane Kimbrough left the ISS decompression chamber at 1658 GMT, some 45 minutes earlier than planned, for a spacewalk to last about 6.5 hours. ... more |

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 Space Software To Control Digital TV Broadcasting 
Paris, France (ESA) Nov 17, 2008Imagine how difficult it is to control a spacecraft thousands of miles away, ensure it arrives at the right location and then get the scientific and photographic equipment up and running. To do this highly sophisticated software is needed; software that can also be used on Earth to manage equally complex TV terrestrial broadcasting. British company SciSys has provided software for a number ... more |

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 India to take second moon shot by 2012, eyes Mars 
New Delhi (AFP) Nov 13, 2008Buoyed by the success of its maiden lunar mission, India on Thursday said it will send a second unmanned spacecraft to the moon by 2012. The announcement came less than a week after Chandrayaan-1, India's first unmanned spacecraft, entered lunar orbit for the start of a two-year mission. The Indian Space Research Organisation (ISRO) said the second spacecraft would also place a probe on ... more
