Phoenix Lander Working With Sticky Soil
Tucson AZ (SPX) Jul 30, 2008Scientists and engineers on NASA's Phoenix Mars Mission spent the weekend examining how the icy soil on Mars interacts with the scoop on the lander's robotic arm, while trying different techniques to deliver a sample to one of the instruments. "It has really been a science experiment just learning how to interact with the icy soil on Mars -- how it reacts with the scoop, its stickiness ... more Phoenix Revises Method To Deliver Icy Sample 
Tucson AZ (SPX) Jul 29, 2008NASA's Phoenix Mars Lander's robotic arm will use a revised collection-and-delivery sequence overnight Sunday with the goal of depositing an icy soil sample in the lander's oven. "We are going to modify the process we ran on Sol 60 to acquire another icy sample and attempt to deliver it to TEGA," the Thermal and Evolved-Gas Analyzer, said Barry Goldstein, Phoenix project manager from NASA ... more Can People Live On Mars 
Moscow (RIA Novosti) Jul 28, 2008The discovery of ice immediately under the surface of Mars is increasing the chances of finding life there. Water is more than the key to the origin of life. Water on Mars raises intriguing questions. Can people build settlements on Mars? Is it suitable for colonization? Can we learn more about our planet by studying the Martian climate? Did Mars go through the same geological processes as ... more Lander Collects Icy Soil But Needs To Work On Delivery 
Tucson AZ (SPX) Jul 28, 2008NASA's Phoenix Mars Lander's robotic arm collected a more than adequate amount of icy soil for baking in one of the lander's ovens but will need to adjust how it delivers samples. Engineers determined the rasping and scraping activity collected a total of 3 cubic centimeters of icy soil, more than enough to fill the tiny oven cell of the Thermal and Evolved-Gas Analyzer, or TEGA. ... more Exploring The Moon With GPS 
Moffett Field CA (SPX) Jul 28, 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 |

Tucson AZ (SPX) Jul 24, 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 Phoenix Completes Longest Work Shift 
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 Mars Sample Return: Bridging Robotic And Human Exploration 
Paris, France (ESA) Jul 22, 2008The first robotic mission to return samples to Earth from Mars took a further step toward realisation with the recent publication of a mission design report by the iMARS Working Group. The report, defines key elements of the future internationally-funded mission involving the cooperation of ESA, NASA and other national agencies. iMARS, which stands for the International Mars ... more |

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 Phoenix Mars Lander Delivers A 3D View Of Its Surrounds 
Pasadena CA (JPL) Jul 18, 2008NASA's Phoenix Mars Mission has released stereo images of the Martian surface near the Phoenix lander. The images in the new 3-D Gallery combine views from the left and right "eyes" of the lander's Surface Stereo Imager (SSI) so that they appear three-dimensional when viewed through red-blue glasses. The first 14 images in the gallery were handpicked by Mark Lemmon, SSI lead scientist ... more
