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 Tom Hill's TEMPO 3 Microsatellite Winner Of Mars Project Challenge 
Washington DC (SPX) Aug 21, 2008After receiving the highest number of votes cast by members of the Mars Society and the endorsement of the Steering Committee, Hill's concept to launch a microsatellite that will test artificial gravity generation techniques - which will be of immense value to the crew of a six-month flight to Mars - was named the winner of the MPC Saturday evening at the 11th Annual International Mars Society ... 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 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 |

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 PSI Director Promotes 13-Planet Solar System 
Columbia, Maryland (SPX) Aug 13, 2008Mark Sykes says that if a non-stellar object is massive enough to be round and orbits a star, it ought to be a planet. The key here is that once an object gets that big, important geophysical processes begin. Under this scenario, the smallest known planet in the solar system would be Ceres, the largest and most massive object in the asteroid belt between Mars and Jupiter. Ceres is less ... more Soil Studies Continue At Phoenix Mars Lander Site 
Pasadena CA (SPX) Aug 13, 2008Vibration of the screen above a laboratory oven on NASA's Phoenix Mars Lander on Saturday, Aug. 9, succeeded in getting enough soil into the oven to begin analysis. Commands were sent for the lander's Thermal and Evolved-Gas Analyzer (TEGA) to begin analysis Sunday of the soil sample from a trench called "Rosy Red." Phoenix's robotic arm delivered soil Thursday from the Rosy Red trench ... more Preparation Begins For New European Space Mission To Mars 
Paris, France (ESA) Aug 12, 2008Scientists searching for life on Mars are now preparing for the most in-depth probe of the Red Planet ever undertaken. The European Space Agency's ExoMars mission will search for evidence that life may exist, investigate the Martian upper atmosphere, and analyse the physical characteristics and properties of the planet's surface and interior. With a scheduled launch date of 2013 ... more |

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 Opportunity Fights Uphill Battle 
Pasadena CA (SPX) Aug 11, 2008"Victoria Crater" continues to challenge Mars rover drivers as they try to find a location where Opportunity can do scientific studies of rocks near the "Cape Verde" cliff face. They have been trying to drive the rover to a location nicknamed "Nevada" after a rock shaped somewhat like the state of Nevada. Getting there, however, has been challenging. After attempting unsuccessfully to ... more With Batteries Charged, Spirit Is Ready For More Science 
Pasadena CA (SPX) Aug 08, 2008Spirit has fully recovered from a recent rundown in battery power. Energy has improved to levels not seen since sol (Martian day) 1604 (July 7, 2008). The hit in battery energy was primarily the result of data transmissions taking place later in the day, when less solar energy was available. During the past week, rover planners eliminated the late communications sessions. Spirit is not ... more Martian Clays Tell Story Of A Wet Past 
Mountain View CA (SPX) Aug 08, 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
