Taking The Opportunity To Escape From Crater Victoria
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 
Tucson AZ (SPX) Sep 01, 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 NASA Mars Rover Opportunity Ascends To Level Ground 
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 Phoenix Lander Pictures Show Robotic Arm's Workspace After 90 Sols 
Tempe AZ (SPX) Aug 29, 2008New pictures from NASA's Phoenix Lander show just what a busy summer the spacecraft on Mars - and its science team at The University of Arizona in Tucson - has been having. During the first 90 Martian days, or sols, after its May 25, 2008, landing on an arctic plain of Mars, the lander dug several trenches in the workspace reachable for its robotic arm. The lander's Surface Stereo ... more |

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 Liquid Water in the Martian North 
Moffett Field CA (SPX) Aug 25, 2008Perchlorate. Never heard of it? Join the club. But NASA's Phoenix spacecraft has found it in the soil in the icy northern plains of Mars. And now that it's been found, scientists are scrambling to explain how it got there, and what, if anything, its presence means about the habitability of the martian north. Phoenix didn't go to Mars to find perchlorate. It went looking for evidence of ... more |

Moffett Field CA (SPX) Aug 22, 2008Before testing for life on other planets, it's useful to practice on barren areas of the Earth. One such place is Rio Tinto in Spain, where conditions are analogous to Mars. The water of that Spanish river is very acidic, similar to water scientists think may have once flowed on the martian surface. Also, chemical studies hint that rocks on Mars' Meridiana Planum plain have been moved by ... more Phoenix Mars Lander Explores Site By Trenching 
Tucson AZ (SPX) Aug 22, 2008NASA'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. Research ... more NASA to use shock-absorbers to fix shaking in new Ares rocket 
Washington (AFP) Aug 20, 2008NASA say they will use shock-absorbers similar to those used in cars to fix a problem with heavy vibrations in the new Ares rocket, to give stronauts inside the Orion crew capsule a smoother ride. US space agency engineers have recommended a system employing spring-mounted weights and shock-absorbing tubes between the first and second stage of the rocket to rectify excessive vibrations. ... more Spirit Waiting Out The Winter 
Pasadena CA (SPX) Aug 18, 2008Spirit's battery levels are slowly edging upward, thanks to a slight decrease in atmospheric dust (Tau) and a gradual increase in sunlight as winter gives way to spring. Early in the week, Spirit spent two Martian days carrying out contingency plans following a temporary delay in data transmission from Earth. Spirit implemented the so-called "runout" portion of an earlier master sequence ... more
