New Theory Explains Ice On Mars
Honolulu HI (SPX) Sep 14, 2007Wobbles on Mars cause ice ages that are much more dramatic than those on Earth, says astronomer Norbert Schorghofer of the University of Hawaii. Thanks to our large, stabilizing Moon, Earth's rotation axis is always tilted by about 23 degrees. The tilt of Mars, however, can wobble by as much as 10 degrees from its current 25 degrees. Wobbles cause big changes in the amount of sunlight reaching ... more Opportunity Begins Sustained Exploration Inside Crater 
Pasadena CA (JPL) Sep 14, 2007NASA's Mars Exploration Rover Opportunity finished the last step of a test in-and-out maneuver checking wheel slippage at the rim of Victoria Crater today. Then the rover immediately drove back into the crater as the start of a multi-week investigation on the big bowl's inner slope. Opportunity started the day with just two of its six wheels inside the rim of Victoria Crater and ended the day's ... more Opportunity Takes A Dip Into Victoria Crater 
Pasadena CA (SPX) Sep 13, 2007NASA's Mars Exploration Rover Opportunity has entered Victoria Crater for the first time. It radioed home information via a relay by NASA's Mars Odyssey orbiter, reporting its activities for the day. Opportunity drove far enough in -- about four meters (13 feet) -- to get all six wheels past the crater rim. Then it backed uphill for about three meters (10 feet). The driving commands for the day ... more The Mysterious Ridges At The Mouth Of Tiu Valles 
Paris, France (ESA) Sep 13, 2007These images taken by the High Resolution Stereo Camera (HRSC) on board Mars Express show the mouth of the Tiu Valles channel system on the red planet. The pictures were taken in orbit 3103 on 10 June 2006 with a ground resolution of approximately 16 metres per pixel. The mouth of Tiu Valles is an estuary-like landform. On Earth, an estuary is the tidal mouth of a river valley, or the end that ... more Dawn One Step Away From Asteroid Belt Trip 
Pasadena CA (JPL) Sep 12, 2007The Dawn spacecraft completed the 25-kilometer (15-mile) journey from Astrotech Space Operations in Titusville, Fla., to Pad-17B of the Cape Canaveral Air Force Station at 5:10 a.m. EDT today. The launch period for Dawn, NASA's eight-year, more than 5-billion-kilometer (3.2-billion-mile) odyssey into the heart of the asteroid belt, opens Sept. 26. "From here, the only way to go is up," said ... more |

Pasadena CA (SPX) Sep 06, 2007Two crucial tools for a successful landing of America's latest mission to Mars, the radar and UHF radio on NASA's Phoenix Mars Lander, have passed in-flight checkouts. The ultra-high-frequency radio won't be turned on again until landing day, May 25, 2008, when it will relay communications from Phoenix to orbiters already in service around Mars. Since launch on Aug. 4, 2007, and until the ... more Scientists And Space Enthusiasts Share Vision For Mars 
Washington DC (VOA) Sep 05, 2007Humans could get to Mars in less than 10 years, if they put their minds to it. That is the message of the Mars Society, a group of scientists and space enthusiasts who met recently in Los Angeles. VOA's Mike O'Sullivan spoke with some about their vision for the exploration and settlement of the Red Planet. They came to see astronaut Buzz Aldrin, one of the first men on the moon, and to ... more 500 Days At Venus, And The Surprises Keep Coming 
Paris, France (SPX) Sep 04, 2007Venus Express has now orbited Earth's twin for 500 Earth days, completing as many orbits. While the satellite maintains steady and excellent performance, the planet continues to surprise and amaze us. In spite of experiencing a challenging environment, Venus Express is in an excellent condition. It receives four times the amount of solar radiation as compared to its sister spacecraft, Mars ... more Phoenix Takes Flight 
Phoenix AZ (SPX) Sep 04, 2007Phoenix is on its way to Mars. The latest spacecraft in NASA's program of Mars exploration launched from Cape Canaveral on August 4 of this year, and is scheduled to land in the planet's northern polar region on May 25, 2008. Its findings will help scientists answer a critical question about the Red Planet: was it ever habitable? Phoenix is in many ways similar to the two Viking landers ... more |

Pasadena CA (SPX) Aug 30, 2007Mars rover scientists have launched a new long-term study on the Martian atmosphere with the Alpha Particle X-ray Spectrometer, an instrument that was originally developed at the University of Chicago. Thanasis Economou, Senior Scientist at Chicago's Enrico Fermi Institute, suggested the new study after observing that the APXS instruments aboard NASA's twin Mars rovers, Spirit and ... more Threatening Conditions For Rovers In Giant Martian Dust Storm 
Pasadean CA (SPX) Aug 30, 2007The mighty Mars rovers Spirit and Opportunity continue to persevere in brutal conditions, as revealed in images of the sun they are sending home. The images show how opaque the Martian atmosphere has been in the face of a raging, two-month dust storm. To understand the gravity of the storm, engineers and astronomers monitor the situation by examining the images of the sun and measuring the ... more HiRISE Confirms Existence of 'Pit Craters' On Mars 
Tuscon AZ (SPX) Aug 30, 2007The High Resolution Imaging Experiment (HiRISE) has confirmed that a dark pit seen on Mars in an earlier HiRISE image really is a vertical shaft that cuts through lava flow on the flank of the Arsia Mons volcano. Such pits form on similar volcanoes in Hawaii and are called "pit craters." The HiRISE camera, orbiting the red planet on NASA's Mars Reconnaissance Orbiter, is the most ... more Calculating The Biomass Of Martian Soil 
Giessen, Germany (SPX) Aug 29, 2007A new interpretation of data from NASA's Viking landers indicates that 0.1% of the Martian soil tested could have a biological origin. This new interpretation of results from NASA's 1976 Viking missions could have important implications for the search for life in our Solar System. Dr Joop Houtkooper of the University of Giessen, Germany, believes that the subfreezing, arid Martian surface ... more
