Phoenix Camera Sees Morning Frost At The Landing Site
Temps AZ (SPX) Aug 18, 2008The Surface Stereo Imager, or SSI, on NASA's Phoenix Mars Lander has seen water frost on the ground around the spacecraft's landing site. Water frost appears in an image the SSI took on Aug. 14, 2008, at 6 a.m. local Mars time on Sol 79, the 79th Martian day after landing. The frost begins to disappear shortly after 6 a.m. as the sun rises on the landing site. The sun was about 22 ... more Martian Clays Tell Story Of A Wet Past 
Mountain View CA (SPX) Aug 18, 2008Layers of clay-rich rock have been found in Mars' Mawrth Vallis, a potential landing site for future rovers. This work, published in the August 8 issue of Science, suggests that abundant water was once present on Mars and that hydrothermal activity may have occurred. The Mawrth Vallis outflow channel is a feature in Mars' northern highland region, a heavily cratered, ancient area of the ... more Phoenix Microscope Takes First Image Of Martian Dust Particle 
Tucson AZ (SPX) Aug 15, 2008NASA's Phoenix Mars Lander has taken the first-ever image of a single particle of Mars' ubiquitous dust, using its atomic force microscope. The particle -- shown at higher magnification than anything ever seen from another world -- is a rounded particle about one micrometer, or one millionth of a meter, across. It is a speck of the dust that cloaks Mars. Such dust particles color the Marti ... more First Test Of Welding Tool For Ares I Upper Stage 
Huntsville AL (SPX) Aug 14, 2008NASA's Marshall Space Flight Center, in Huntsville, Ala., engineers made the first "official" weld with tools that will enable development of the upper stage of the Ares I rocket. For this historic moment, the engineers used tools that soon will aid in manufacture of major test hardware for the Ares I rocket, slated to carry human missions back to the moon, on to Mars and out into the solar syst ... more Water Ideas Are All Wet 
Moffett Field CA (SPX) Aug 14, 2008According to new research, old ideas about water behavior are all wet. Ubiquitous on Earth, water also has been found in comets, on Mars and in molecular clouds in interstellar space. Now, scientists say this common fluid is not as well understood as we thought. "Water, as we know it, does not exist within our bodies," said Martin Gruebele, a William H. and Janet Lycan Professor of Chemist ... more |

Tucson AZ (SPX) Aug 11, 2008NASA'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 soil into a gap between partially opened doors to an analytical oven on the lander. Phoenix's robotic arm delivered soil Thursday from a trench informally named "Rosy Red" through a narrow opening to ... more Professor Plays Vital Role In Mars Water Breakthrough 
Pasadena CA (SPX) Aug 11, 2008NASA's Phoenix Mars Lander has recently confirmed what space scientists have suspected for a long time: There is water on Mars. UT Dallas Physics Professor John Hoffman, a member of the William B. Hanson Center for Space Sciences, is at the center of the discovery. Hoffman's mass spectrometer is the system that analyzed gases from soil samples, the step needed to prove the existence ... more Chasing Dust Devils 
Tucson AZ (SPX) Aug 11, 2008"It's a bit of an art - learning how to drive across dry lake beds at great speed," says Matt Balme. "And it can be quite hairy as well." During the next three years, Balme will spend a lot of time careening across playas and other open, desert areas to better understand dust devils on Mars - how much dust they lift into the atmosphere and how this affects the martian climate. Understanding ... more ROTOZIP Duracut Bit Helps Phoenix Collect Martian Soil Samples 
Mt. Prospect IL (SPX) Aug 11, 2008The ROTOZIP Duracut Zip Bit, paired with a high-speed rasp, has enabled NASA's Phoenix Lander to collect valuable soil samples. NASA scientists confirmed the ROTOZIP-enabled rasp is the first tool in history to successfully cut into the permafrost surface of another planet and acquire a sample for analysis. To date, samples have led to the discovery of water on Mars and helped identify an ... more |

Tucson (UPI) Aug 6, 2008 U.S. space agency scientists say the discovery of perchlorate salts on Mars makes them reassess how they think about possible Martian life. Scientists involved with the Phoenix Mars Lander mission met Tuesday in an ongoing investigation of perchlorate salts detected in soil analyzed by the spacecraft's wet chemistry laboratory. The discovery of Martian perchlorates is exciting ... more 4Frontiers Awarded Grant To Investigate Mars Greenhouse Materials 
Tampa FL (SPX) Aug 06, 20084Frontiers Corporation, a NewSpace technology, entertainment and education company, is pleased to announce that it has been awarded a $25,000 research grant from the Florida Space Grant Consortium (FSGC), as part of the Florida Space Research and Education Grant Program. This grant will assist 4Frontiers in pursuing its technology roadmap for Mars settlement technologies. The project's ... more About Water On Mars, The Origins Of Life And The Future Of Earth 
Moscow (RIA Novosti) Aug 06, 2008"Martian water has been touched and tasted" by NASA's Phoenix lander spacecraft, which has identified water in a sample of soil collected from Mars. This will expand our so far fragmented and incomplete knowledge about the origins of the Solar System. It will also benefit evolutionary biologists looking for the origins of life. Currently they can study life on Earth, which is not enough ... more Phoenix Mars Team Opens Window On Scientific Process 
Pasadena CA (SPX) Aug 06, 2008Phoenix 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 ... more
