Spirit Continues Soil Analysis
Pasadena CA (SPX) May 28, 2007Spirit is healthy and spent the last week studying light and dark soil in and around the rover's tracks between "Home Plate" and "Mitcheltree Ridge." Spirit collected additional soil data, including about 24 hours of data using the alpha-particle X-ray spectrometer and 70 hours of data using the Mossbauer spectrometer. The primary soil targets examined during the week are known as ... more Opportunity Turns Up The Amps 
Pasadena CA (SPX) May 28, 2007Opportunity's electrical supply returned to levels not seen since the rover first arrived on Mars. Peak electrical current from the rover's solar arrays climbed above 4.0 amps and remained there for most of the week as a result of three recent dust-cleaning events. The last time electrical current reached similar levels was on sol 18 (Feb. 10, 2004)! Meanwhile, Opportunity is healthy an ... more ICO Signs Launch Services And Dual Launch Study Agreement With ILS 
Reston VA (SPX) May 28, 2007ICO Global Communications has signed a Launch Services and Dual Launch Study Agreement with ILS International Launch Services (ILS). With this contract, ICO has established a Proton launch services agreement for up to five launches in the 2009 through 2011 timeframe. In addition, ILS will design and propose a dual launch capability for ICO's Medium Earth Orbit (MEO) satellites. Bob Day ... more Seeking Mars Survival Secrets 
Princeton NJ (SPX) May 23, 2007David Smith always wondered whether other planets might harbor life, so when he actually got the opportunity to investigate, he jumped at it. His decision launched him on a year-long mission, leading him to the Kennedy Space Center and back. Now, after long months exploring whether Earth bacteria can survive on the surface of Mars, he has returned with findings that could help NASA plan better m ... more Mars Rover Spirit Unearths Surprise Evidence Of Wetter Past 
Pasadena CA (SPX) May 22, 2007A patch of Martian soil analyzed by NASA's rover Spirit is so rich in silica that it may provide some of the strongest evidence yet that ancient Mars was much wetter than it is now. The processes that could have produced such a concentrated deposit of silica require the presence of water. Members of the rover science team heard from a colleague during a recent teleconference that the alpha ... more |

Pasadena CA (SPX) May 15, 2007Pasadena CA (SPX) May 15, 2007 Spirit is healthy and has finished investigating a patch of churned-up, white-toned, silica-rich material known as "Gertrude Weise." Meanwhile, the rover's first attempt to autonomously place and exchange scientific instruments at the same target was partially successful. Spirit backed up over Gertrude Weise to a spot 2 meters (6.6 feet) beyond it and placed the M ... more Next Mars Lander Crosses The Mississippi 
Cape Canaveral FL (SPX) May 09, 2007A U.S. Air Force C-17 cargo aircraft carried NASA's Phoenix Mars Lander spacecraft Monday, May 7, from Colorado to Florida, where Phoenix will start a much longer trip in August. After launch, Phoenix will land on a Martian arctic plain next spring. It will use a robotic digging arm and other instruments to determine whether the soil environment just beneath the surface could have been a favorab ... more Spirit Examined Light - Colored Material Near Home Plate 
Pasadena CA (SPX) May 08, 2007Spirit is healthy and has completed its investigation of a knobby rock target known as "GoodQuestion." Next on Spirit's itinerary is a drive to the north and an attempt to climb onto "Home Plate." On the way, Spirit will examine white--toned material where one of the rover's wheels disturbed the soil. Observations using the miniature thermal emission spectrometer suggest it may be enriched ... more Opportunity Conducts Path Planning Test And Gets Another Energy Boost 
Pasadena CA (SPX) May 08, 2007Opportunity drove 224 meters (735 feet) this week. The sol 1160 checkout of the D-star hazard avoidance path planner (drive planning software) was a resounding success. In order to make the test as safe as possible, D-star was told that rocks in its path were hazards, when actually Opportunity is capable of safely driving over them. The rover planners set a waypoint on the opposite side of ... more |

Pasadena CA (SPX) May 03, 2007Scientists and engineers are still deciding on when and if Opportunity will enter "Victoria Crater." In the meantime, Opportunity has a lot to accomplish, such as driving back to the area of its original arrival at Victoria, approximately 600 meters away (over one-third of a mile). In addition, Opportunity must complete checkouts of its new technologies such as the D-star hazard avoidance ... more Spirit Discovers Changes In Soil Near Home Plate 
Pasadena CA (SPX) May 02, 2007Spirit remains healthy after completing scientific investigation of a light-toned soil patch nicknamed "Everett." Everett is interesting because scientists thought it would be rich in sulfur like other soil exposures they've investigated. Instead, it turned out to be low in sulfur and ultramafic in composition -- made of iron- and magnesium-rich silicate, a chemistry often associated with volcan ... more Instruments To Dig Deep In Space 
Fayetteville AR (SPX) Apr 30, 2007University of Arkansas researchers, in partnership with a local company will develop a probe for future planetary rovers that will help scientists study the history of the solar system by examining the properties of layers of material beneath the surface of the moon, Mars, comets and other planetary bodies. Scientists at the Arkansas Center for Space and Planetary Sciences and officials of ... more Canadians Teaming Up To Develop Mars Mission Concepts 
Longueuil, Quebec, April 24, 2007When a mission to Mars is being developed, mission planners must consider many factors. Space technology advances, scientific needs and objectives, how to deal with distance, communications delays, and landing through the thin Martian atmosphere-all this must converge into a useful, workable mission concept. Canadian companies and researchers are part of an international drive to respond t ... more
