NASA's Phoenix Mars Lander Prepares For Next Sample Analysis
Tucson AZ (SPX) Jul 25, 2008The latest activities of NASA's Phoenix Mars Lander have moved the mission closer to analyzing a sample of material, possibly icy soil, from a hard layer at the bottom of a shallow trench beside the lander. Overnight Tuesday to Wednesday, during Phoenix's 57th Martian day, or sol, since landing, Phoenix used its robotic arm to scrape the top of the hard layer in the trench informally named ... more New Project To Develop GPS-Like System For Moon 
Columbus OH (SPX) Jul 25, 2008The same Ohio State University researcher who is helping rovers navigate on Mars is leading a new effort to help humans navigate on the moon. When NASA returns to the moon -- the space agency has set a target date of 2020 to do so -- astronauts won't be able to use a global positioning system (GPS) to find their way around, explained Ron Li, the Lowber B. Strange Designated Professor of ... more NASA's Phoenix Mars Lander Prepares For Next Sample Analysis

Tucson AZ (SPX) Jul 24, 2008Phoenix early Tuesday finished its longest work shift of the mission. The lander stayed awake for 33 hours, completing tasks that included rasping and scraping by the robotic arm, in addition to atmosphere observations in coordination with simultaneous observations by NASA's Mars Reconnaissance Orbiter. "Our rasping test yesterday gave us enough confidence that we're now planning for the ... more NASA's Phoenix Mars Lander Works Through the Night 
Tucson AZ (SPX) Jul 22, 2008To coordinate with observations made by an orbiter flying repeatedly overhead, NASA's Phoenix Mars Lander is working a schedule Monday that includes staying awake all night for the first time. Phoenix is using its weather station, stereo camera and conductivity probe to monitor changes in the lower atmosphere and ground surface at the same time NASA's Mars Reconnaissance Orbiter studies ... more |

Pasadena CA (SPX) Jul 21, 2008The team operating NASA's Phoenix Mars Lander plans to tell the lander to do a second, larger test of using a motorized rasp to produce and gather shavings of frozen ground. The planned test is a preparation for putting a similar sample into one of Phoenix's laboratory ovens in coming days. The instrument with the oven, the Thermal and Evolved- Gas Analyzer, called TEGA, will be used ... more NASA Spacecraft Shows Diverse, Wet Environments On Ancient Mars 
Washington DC (SPX) Jul 21, 2008Two studies based on data from NASA's Mars Reconnaissance Orbiter have revealed that the Red Planet once hosted vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life. One study, published in the July 17 issue of Nature, shows that vast regions of the ancient highlands of Mars, which cover about half the planet, contain clay minerals, which ... more A Workday On Mars Is More Than 9-to-5:40 
Dallas TX (SPX) Jul 21, 2008The average day, or "sol," on Mars is 40 minutes longer than our 24-hour day on Earth. UT Dallas Physics Professor John Hoffman has spent more than 50 days on Martian time analyzing soil from the surface of the Red Planet. Hoffman, a member of the UT Dallas William B. Hanson Center for Space Sciences, designed a mass spectrometer system that analyzes gases from soil samples heated in eight ... more Spoting The Differences Between Alaska And Mars 
Moffett Field CA (SPX) Jul 18, 2008Little did Bucknell University geology professors Craig Kochel and Jeffrey Trop know as they were working in Alaska that they would soon predict one of the most important planetary observations ever made. The pair were in Alaska for an eight day trip in July 2006, studying geological features and the processes that create them. As they studied photographs taken of the surrounding area ... more |

Tucson AZ (SPX) Jul 17, 2008A powered rasp on the back of the robotic arm scoop of NASA's Phoenix Mars Lander successfully drilled into the frozen soil and loosened material that was collected in the lander's scoop. Images and data sent from Phoenix early Wednesday indicated the shaved material in the scoop had changed slightly over time during the hours after it was collected. The motorized rasp -- located on ... more Mars Express To Rendezvous With Martian Moon 
Paris, France (ESA) Jul 17, 2008Scientists and engineers are preparing ESA's Mars Express for a pair of close fly-bys of the Martian moon Phobos. Passing within 100 km of the surface, Mars Express will conduct some of the most detailed investigations of the moon to date. The series of fly-bys will take place between 12 July and 3 August. During the second encounter, the spacecraft will fly within 273 km of the surface. ... more Ancient Mars Was A Diverse Complex World

Paris (AFP) July 15, 2008Pluto - downgraded two years ago to the status of a dwarf planet - has an exotically-named chum on the fringes of the Solar System. The Paris-based International Astronomical Union has decided to honour a Kuiper Belt object, 2005 FY9, with the name of Makemake, after the creator of humanity and the god of fertility in the Rapa Nui culture of Easter Island. ... more
