Rover Finds Way To Brush Rock Surfaces Despite Setbacks
Pasadena CA (JPL) Nov 15, 2007Opportunity is still parked in front of the rock layer known as "Smith" inside Victoria Crater. The rover has now lost two encoders that operate motors on the rock abrasion tool during the grinding and brushing of surfaces. Science team members and engineers have been working in test beds and computer sequencing rooms to devise creative ways of using the rock abrasion tool without the grind and ... more Opportunity's Rock Abrasion Tool Shows Anomalous Behavior 
Pasadena CA (SPX) Nov 14, 2007During the past week, Opportunity continued to investigate the rock layer known as "Smith," the second of three "bathtub-ring" layers of rock inside "Victoria Crater." The vehicle is mostly healthy, except for a recent anomaly involving the rock abrasion tool. Planned operations with the rock abrasion tool failed on Martian day, or sol, 1334 (Oct. 25, 2007), during both the calibration and ... more Spirit Continues Drive As Power Levels Decline 
Pasadena CA (SPX) Nov 14, 2007Spirit has been gradually losing power, with energy levels dropping to 320 watt-hours per Martian day (100 watt-hours is the amount of energy needed to light a 100-watt bulb for one hour). Measurements of atmospheric dust, known as Tau, have been averaging 0.65. That dust level is typical of levels measuring throughout most of the mission, but power levels are lower than in previous years becaus ... more The Appeal Of Mars 
Moscow (RIA Novosti) Nov 12, 2007Despite the numerous technical and medical-biological problems it would face, a manned mission to Mars is being spoken about with more and more certainty. Yet it is unclear why we should take such great risks to land astronauts on the Red Planet. Nor do we know whether the huge costs of such an expedition would ever be recouped. Yury Semyonov, a member of the Russian Academy of Sciences an ... more China to accept private funding for lunar missions 
Beijing (AFP) Nov 8, 2007China will accept private investment to help put a man and a rover on the moon, seeking outside funding for its expanding space ambitions, state media said Thursday. The funding opportunities will be open to "competent institutions and enterprises," the Shanghai Daily quoted a spokesman for the China National Space Administration as saying. "They could include scientific research organs, ... more |

Pasadena CA (SPX) Nov 08, 2007A promontory nicknamed "Cape Verde" can be seen jutting out from the walls of Victoria Crater in this approximate true-color picture taken by the panoramic camera on NASA's Mars Exploration Rover Opportunity. The rover took this picture on martian day, or sol, 1329 (Oct. 20, 2007), more than a month after it began descending down the crater walls - and just 9 sols shy of its second Martian birth ... more Shuttle Discovery heads home after ambitious, risky mission 
Washington (AFP) Nov 5, 2007The US shuttle Discovery undocked from the International Space Station on Monday, wrapping up a complex mission marked by a daring spacewalk to repair a torn solar array. After saying goodbye to their space station colleagues and closing the hatches, Discovery crew members smoothly sailed away from the ISS at 5:32 am (1030 GMT) before a scheduled landing set for Wednesday at 1802 GMT in Flor ... more Opportunity Studies Rock Composition And Changes In Atmosphere 
Pasadena CA (SPX) Nov 06, 2007Though atmospheric dust has returned to nearly pre-dust storm levels, Opportunity's solar arrays are still dustier than before the storm, keeping power levels about 200 watt-hours lower than pre-storm levels. Opportunity continues to generate solar power levels of more than 600 watt-hours per Martian day, or sol (100 watt-hours is the amount of energy required to light a 100-watt bulb for one h ... more Spirit To Head North For The Winter 
Pasadena CA (SPX) Nov 05, 2007With Martian winter approaching, the science and engineering teams have been hard pressed to select a site where Spirit can spend the winter. After previously narrowing the list of candidates to two sites, Spirit's handlers decided to send the rover to the northern edge of the elevated plateau known as "Home Plate," which Spirit has been exploring for many months now. ... more |

Pasadena CA (SPX) Nov 02, 2007The radar system on the European Space Agency's Mars Express orbiter has uncovered new details about some of the most mysterious deposits on Mars: the Medusae Fossae Formation. It has provided the first direct measurement of the depth and electrical properties of these materials, providing new clues about their origin. The Medusae Fossae Formation consists of enigmatic deposits. Found near ... more Space station's solar panel needs crucial repair 
Washington (AFP) Oct 31, 2007Two astronauts will try to fix a torn solar panel on the International Space Station during a space walk that has become crucial for the orbiting laboratory's mission, NASA said Wednesday. NASA plans to send the astronauts, members of the shuttle Discovery crew who arrived at the station last week, outside the orbiting laboratory on Friday to repair a solar wing that ripped when it was deplo ... more Panel on space station solar antenna rips
Washington (AFP) Oct 30, 2007NASA scientists were Tuesday examining the damage to a panel on a solar antenna on the International Space Station which ripped as it was repositioned by the crew of the shuttle Discovery. "The team is meeting right now to look at these many pictures and try to decide what exactly is causing the problem," said Mike Suffredini, the manager of the orbiting space station. "We don't clearly ... more US shuttle mission to ISS extended 
Washington (AFP) Oct 30, 2007NASA said on Tuesday it would extend the space shuttle Discovery's mission by one day to allow for a closer inspection of a flawed rotary joint that turns the solar arrays aboard the International Space Station. The decision was taken by the director of the orbiting space lab, Mike Suffredini, on Monday and relayed Tuesday to the Discovery crew by mission control in Houston. As the US sp ... more
