Dawn Spacecraft View Of Mars
Pasadena CA (SPX) Feb 23, 2009This near-infrared image from the framing camera on NASA's Dawn spacecraft was taken near the point of closest approach to Mars on Feb. 17, 2009, during Dawn's gravity assist flyby. The image, taken for calibration purposes, shows a portion of the fretted and cratered northwest margin of Tempe Terra, Mars. The scarp of the highlands/ lowlands boundary is illuminated by the light of ... more Dawn Changes Course Near Mars 
Bonn, Germany (SPX) Feb 18, 2009On 18 February 2009 the gravity of Mars, our neighbouring planet, will move the spacecraft Dawn onto the correct path for its onward flight to the asteroid Vesta. During this close fly-by of the red planet, researchers will test the German camera system that is on board the spacecraft. The plan is to compare photographs taken during the fly-by with those taken by HRSC, the stereo camera ... more As Dawn Approaches Mars, PSI Scientists Gear Up For GRaND Tests 
Pasadena CA (SPX) Feb 17, 2009The Dawn spacecraft, which began its journey to the asteroid belt in 2007, is now nearing Mars, and scientists at the Tucson-based Planetary Science Institute (PSI) are preparing to use the encounter to tune up Dawn's GraND instrument. Dawn's instrument payload includes a visible-light camera, a visible-light and infrared mapping spectrometer, and GraND (the Gamma-Ray and Neutron Detector) ... more Spirit Gets Energy Boost From Cleaner Solar Panels 
Pasadena CA (SPX) Feb 14, 2009A small but important uptick in electrical output from the solar panels on NASA's Mars Exploration Rover Spirit this month indicates a beneficial Martian wind has blown away some of the dust that has accumulated on the panels. The cleaning boosts Spirit's daily energy supply by about 30 watt-hours, to about 240 watt-hours from 210 watt-hours. The rover uses about 180 watt-hours ... more Detailed map shows dry Moon 
Washington (AFP) Feb 12, 2009A new detailed map of the Moon released Thursday shows the Earth's satellite holds very little water and reveals never-before seen craters at the poles, an international research team said. "The surface can tell us a lot about what's happening inside the Moon, but until now mapping has been very limited," C.K Shum, professor of Earth sciences at Ohio State University, said in the February 13 ... more |

Paris (AFP) Feb 10, 2009The European Space Agency (ESA) on Tuesday announced it was extending successful unmanned missions to Mars and Venus as well as a satellite exploration of Earth's magnetic field. The decision would extend the Mars Express, Venus Express and Cluster missions until December 31, ESA said in a press release. Mars Express, launched in 2003, "has produced a treasure of discoveries," ESA said, ... more NASA Receives Shorty Twitter Award 
Washington DC (SPX) Feb 11, 2009NASA's activities in social networking media will be recognized Wednesday in New York, when the agency receives an award for its presence on the popular Web site Twitter. Known as the Shorty Award, it was created to honor the best producers of short content on Twitter during 2008. Updates on NASA's Mars Phoenix Lander mission received the most votes in the science category from users of ... more Martian Crater Features Suggest Influence Of Water And Ice 
Tucson AZ (SPX) Feb 10, 2009Scientists at the Tucson-based Planetary Science Institute (PSI) have found further evidence for the large role that water has likely played in shaping the Martian landscape. Their results, which will be published in "Icarus", provide strong evidence that multiple wet and/or icy climate cycles have shaped the topography of the planet's large craters. "Icarus" is the journal of the American ... more Spirit Update: On the Move - sol 1791-1797 
Pasadena CA (SPX) Feb 11, 2009Communication problems during the Martin Luther King, Jr. Holiday led to the postponement of a drive planned for sol 1791 (Jan. 15, 2009) to sol 1793 (Jan. 17, 2009). Once the drive began, however, Spirit was able to go ahead with characterization of a rock target known as "Stapledon." Studies began with a stack of microscopic images taken at different focal lengths, then moved to ... more |

Pasadena CA (SPX) Feb 04, 2009NASA's Mars Exploration Rover Spirit resumed driving Saturday after engineers gained confidence from diagnostic activities earlier in the week evaluating how well the rover senses its orientation. Spirit drove about 30 centimeters (1 foot) Saturday, during the 1,806th Martian day, or sol, of what was originally planned as a 90-day mission. The rover team had commanded a longer drive, but ... more NASA And Google Launch Virtual Exploration Of Mars 
Moffett Field CA (SPX) Feb 03, 2009NASA and Google announced Monday the release of a new Mars mode in Google Earth that brings to everyone's desktop a high-resolution, three-dimensional view of the Red Planet. Besides providing a rich, immersive 3D view of Mars that will aid public understanding of Mars science, the new mode, Google Mars 3D, also gives researchers a platform for sharing data similar to what Google Earth ... more Roscosmos Eyes New Station 
Moscow (RIA Novosti) Jan 30, 2009Russia's Federal Space Agency (Roscosmos) will propose to the government the construction of a low-orbit space station to support future exploration of the Moon and Mars, an agency official said Thursday. "We will soon propose to our government a project to construct a low-orbit complex, which could serve as a foundation for the implementation of the lunar program and later on - the Mars ... more Early Attempts To Contact Aliens 
Moffett Field CA (SPX) Jan 30, 2009The desire to contact intelligent life on other planets is much older than the UFO craze and the SETI movement. Several 19th century scientists contemplated how we might communicate with possible Martians and Venusians. These early proposals - which predate by 150 years the first extraterrestrial message that was sent in 1974 - were based on visual signals, as the invention of radio was ... more
