Spiky Probe On Phoenix Raises Vapor Quandary
Tucson AZ (SPX) Sep 05, 2008A 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 ... more Opportunity To Exit Victoria Crater 
Pasadena CA (JPL) Sep 05, 2008Like a backpacker hiking up a steep grade, Opportunity has been trying to gain elevation using a "switchback" approach inside "Victoria Crater." The rover's goal was to zigzag back and forth across a steep slope toward an outcrop nicknamed "Nevada," where scientists had hoped to do scientific analysis and collect high-resolution, panoramic images of the cliff face known as "Cape Verde." ... more Billion-dollar European probe set for asteroid encounter 
Paris (AFP) Sept 3, 2008Far from Earth, a robot spacecraft has been prodded from deep slumber to make a rare encounter with an asteroid, the intriguing orbital debris that could offer clues into the making of the Solar System. The pride of the European Space Agency (ESA), the probe Rosetta has been ordered out of hibernation four and a half years into a 10-year trek that will take it into the dark chill of deep ... more Phoenix Mission Conducting Extended Activities On Mars 
Tucson AZ (SPX) Sep 03, 2008NASA's Phoenix Mars Lander, having completed its 90-day primary mission, is continuing its science collection activities. Science and engineering teams are looking forward to at least another month of Martian exploration. Due to the spacecraft's sufficient power and experiment capacity, NASA announced on July 31 that the mission would continue operations through Sept. 30. Once the lander ... more Phoenix Analyzing Deepest Soil Sample Yet 
Tucson, AZ (JPL) Sep 03, 2008Scientists 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 ... more |

Pasadena CA (JPL) Sep 01, 2008NASA's Mars Exploration rover Opportunity is heading back out to the Red Planet's surrounding plains nearly a year after descending into a large martian crater to examine exposed ancient rock layers. Opportunity will continue its mission to characterize the environment of Mars and help scientists determine if the planet could have been a habitat for past life in our solar system. "We've do ... more Phoenix Mission Conducting Extended Activities On Mars

Pasadena CA (SPX) Sep 01, 2008NASA's Mars Exploration Rover Opportunity has climbed out of the large crater that it had been examining from the inside since last September. "The rover is back on flat ground," an engineer who drives it, Paolo Bellutta of NASA's Jet Propulsion Laboratory, announced to the mission's international team of scientists and engineers. Opportunity used its own entry tracks from nearly a ... more Antarctic Research Helps Shed Light On Climate Change On Mars 
Boston MA (SPX) Sep 01, 2008Researchers examining images of gullies on the flanks of craters on Mars say they formed as recently as a few hundred thousand years ago and in sites once occupied by glaciers. The features are eerily reminiscent of gullies formed in Antarctica's mars-like McMurdo Dry Valleys. The parallels between the Martian gullies and those in Antarctica's McMurdo Dry Valleys were made using the latest ... more |

Tempe AZ (SPX) Aug 27, 2008From the location of NASA's Phoenix Mars Lander, above the Martian arctic circle, the sun does not set during the peak of the Martian summer. This period of maximum solar energy is past -- on Sol 86, the 86th Martian day after the Phoenix landing, the sun fully set behind a slight rise to the north for about half an hour. This red-filter image taken by the lander's Surface Stereo ... more Dawn Advances Slowly 
Pasadena CA (SPX) Aug 27, 2008The Dawn spacecraft continues to make good progress on its adventure to unlock scientific secrets hidden deep in the main asteroid belt, between Mars and Jupiter. Its path to that distant realm of the solar system is now bringing it closer to the Sun, and thanks in part to all the thrusting it has accomplished with its remarkable ion propulsion system, it has recently achieved its lowest speed ... more Seeing Mars In A Particle Of Dust 
Moffett Field CA (SPX) Aug 27, 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 ... more Phoenix Digs Deeper As Third Month Nears End 
Tucson AZ (SPX) Aug 26, 2008The 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 lander ... more
