By Daniel Stolte, University Communications, and NASA's Jet Propulsion Laboratory An instrument designed and built at the University of Arizona measured the isotopic composition of the Mars atmosphere, providing information about water on the planet Liquid water has interacted with the Martian surface throughout Mars' history, measurements by NASA's Phoenix Mars Lander suggest. The findings, published in the Sept. 10 issue of the journal Science, also suggest that liquid water has primarily...

PASADENA, Calif. -- In a race against time and the elements, engineers with NASA's Phoenix Mars Lander mission hope to extend the lander's survival by gradually shutting down some of its instruments and heaters, starting today. Originally scheduled to last 90 days, Phoenix has completed a fifth month of exploration in the Martian arctic. As expected, with the Martian northern hemisphere shifting from summer to fall, the lander is generating less power due to shorter days and fewer hours of...

NASA's Phoenix Mars Lander has detected snow falling from Martian clouds. Spacecraft soil experiments also have provided evidence of past interaction between minerals and liquid water, processes that occur on Earth. A laser instrument designed to gather knowledge of how the atmosphere and surface interact on Mars has detected snow from clouds about 4 kilometers (2.5 miles) above the spacecraft's landing site. Data show the snow vaporizing before reaching the ground. "Nothing like this view...

The next soil sample that NASA's Phoenix Mars Lander will deliver to its deck instruments will go to the fourth of the four cells of Phoenix's wet chemistry laboratory, according to the Phoenix team's current plans. The chosen source for that sample is from the "Snow White" trench on the eastern end of the work area reachable with Phoenix's robotic arm. In July that trench yielded a sample in which another analytical instrument, the Thermal and Evolved Gas Analyzer (or TEGA), confirmed the...

NASA's Phoenix Mars Lander has scooped up a soil sample from an intermediate depth between the ground surface and a subsurface icy layer. The sample was delivered to a laboratory oven on the spacecraft. The robotic arm on Phoenix collected the sample, dubbed "Burning Coals," from a trench named "Burn Alive 3." The sample consisted of about one-fourth to one-half teaspoon of loose soil scooped from depth about 3 centimeters (1.2 inch) below the surface of the ground and about 1 centimeter (0.4...

NASA's Phoenix Mars Lander scientists and engineers are continuing to dig into the area around the lander with the spacecraft's robotic arm, looking for new materials to analyze and examining the soil and ice subsurface structure. New trenches opened recently include the "Burn Alive 3" trench in the "Wonderland" digging area in the eastern portion of the arm's reachable workspace. Researchers choose such names informally to aid discussion. The team is excavating one side of Burn Alive 3 down...

Vibration of the screen above a laboratory oven on NASA's Phoenix Mars Lander on Saturday succeeded in getting enough soil into the oven to begin analysis. Commands were sent for the lander's Thermal and Evolved-Gas Analyzer to begin analysis Sunday of the soil sample from a trench called "Rosy Red." NASA's Phoenix Mars Lander has continued studies of its landing site by widening a trench, making overnight measurements of conductivity in the Martian soil and depositing a sample of surface...

Phoenix Mars mission scientists spoke today on research in progress concerning an ongoing investigation of perchlorate salts detected in soil analyzed by the wet chemistry laboratory aboard NASA's Phoenix Lander. "Finding perchlorates is neither good nor bad for life, but it does make us reassess how we think about life on Mars," said Michael Hecht of NASA's Jet Propulsion Laboratory, Pasadena, Calif., lead scientist for the Microscopy, Electrochemistry and Conductivity Analyzer (MECA), the...

NASA's Phoenix Lander may have discovered the presence of perchlorate, a chemically reactive salt, in soil samples taken from the surface of Mars, NASA scientists said on Monday. If the finding is confirmed, it could add doubt to the theory of conditions on the planet being able to sustain life. The space agency will be working to determine whether the perchlorate came from the Martian soil or the spacecraft. Perchlorate is an oxidizing substance used in rocket fuel. It is known to be...
