PASADENA, Calif. -- Scientists are analyzing results from soil samples delivered several weeks ago to science instruments on NASA's Phoenix Mars Lander to understand the landing site's soil chemistry and mineralogy. Within the last month, two samples have been analyzed by the Wet Chemistry Lab of the spacecraft's Microscopy, Electrochemistry, and Conductivity Analyzer, or MECA, suggesting one of the soil constituents may be perchlorate, a highly oxidizing substance. The Phoenix team has been...

By Stephanie Innes, The Arizona Daily Star, Tucson Aug. 1--The red planet really does have water. The Phoenix Mars Mission led by the University of Arizona has made history by scientifically proving, for the first time, that water exists on a planet other than Earth. "We have water," the UA's William V. Boynton, a lead scientist on the NASA mission, announced Thursday in Tucson. "We've done most of the things we need to do for a fully successful mission," Boynton added. "It is a...

Laboratory tests aboard NASA's Phoenix Mars Lander have identified water in a soil sample. The lander's robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples. "We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA. "We've seen evidence for this water ice before in observations by the Mars Odyssey orbiter and in disappearing chunks observed by Phoenix...

Scientists 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, whether it's better to have it in the shade or the sunlight," said Phoenix Principal Investigator Peter...

NASA'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's Jet Propulsion Laboratory in Pasadena, Calif. "We will repeat what we did successfully with small...

The 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 "Snow White." The Phoenix team prepared commands to send to the spacecraft Wednesday telling it to take...

Phoenix 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 next use of the rasp to be for acquiring a sample to be delivered to TEGA," said Phoenix project manager...

Arizona Gov. Janet Napolitano visited the Phoenix mission Science Operations Center at The University of Arizona Monday to see how NASA's Phoenix Mars Lander was progressing. UA's Peter Smith, Phoenix principal investigator, showed Napolitano panoramic images taken by the Surface Stereo Imager (SSI) on the lander. The panoramas were projected onto five adjacent screens that displayed the images 11 feet tall and 70 feet wide. Smith said that seeing the large-sized images made a big impression...

To 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 the atmosphere and ground from above. The lander's fork-like thermal and conductivity probe was inserted...
