TUCSON, Ariz. -- A fork-like conductivity probe has sensed humidity rising and falling beside NASA's Phoenix Mars Lander, but when stuck into the ground, its measurements so far indicate soil that is thoroughly and perplexingly dry. "If you have water vapor in the air, every surface exposed to that air will have water molecules adhere to it that are somewhat mobile, even at temperatures well below freezing," said Aaron Zent of NASA Ames Research Center, Moffett Field, Calif., lead scientist...

Scientists have begun to analyze a sample of soil delivered to NASA's Phoenix Mars Lander's wet chemistry experiment from the deepest trench dug so far in the Martian arctic plains. Phoenix has also been observing movement of clouds overhead. The lander's robotic arm on Sunday sprinkled a small fraction of the estimated 50 cubic centimeters of soil that had been scooped up from the informally named "Stone Soup" trench on Saturday, the 95th day of the mission. The Stone Soup trench, in the...

As the sun dips lower in the Martian sky with each passing day, NASA's solar-powered Phoenix Mars Lander took time this week to send a postcard of sorts to scientists on Earth after more than three months studying the red planet. Phoenix beamed home a view of its trench-filled worksite after surpassing the 90-day mark of its initial mission to hunt for water ice buried beneath the barren arctic plains of Mars. While the Martian days, or sols, are getting colder and the sun expected to dip...

TUCSON, Ariz. -- The next sample of Martian soil being grabbed for analysis is coming from a trench about three times deeper than any other trench NASA's Phoenix Mars Lander has dug.On Tuesday, Aug. 26, the spacecraft will finish the 90 Martian days (or "sols") originally planned as its primary mission and will continue into a mission extension through September, as announced by NASA in July. Phoenix landed on May 25."As we near what we originally expected to be the full length of the...

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...

The U.S. space agency says its Phoenix Mars Lander has used an atomic force microscope to take the first-ever image of a single particle of Mars' dust. National Aeronautics and Space Administration scientists said the rounded particle has a diameter of about one micrometer, or one millionth of a meter, and is a speck of the dust that colors the Martian sky pink and its soil a distinctive red. "This is the first picture of a clay-sized particle on Mars, and the size agrees with predictions...

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...

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...

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...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
