Phoenix Landing Area Viewed By Mars Color Imager
Pasadena CA (JPL) May 08, 2008NASA's Phoenix Mars Lander is scheduled to land on the Martian northern plains near 68 degrees north latitude, 127 degrees west longitude on May 25, 2008. In preparation for the landing, NASA's Mars Reconnaissance Orbiter has been monitoring weather in the region around the landing site. On April 20, 2008, the orbiter's Mars Color Imager camera captured this view of a large region of north ... more Opportunity Investigates Arthritic Rover Joint 
Pasadena CA (SPX) May 07, 2008Opportunity is healthy and all subsystems are performing as expected, with the exception of the Instrument Deployment Device (the robotic arm). Power has improved slightly during the last week, primarily as the result of a better state of charge in the batteries. Given the recent difficulties with the robotic arm, the rover hasn't been using the batteries as much as usual. Energy has ... more Is There Life On Mars - Ask A Magnet 
Moffett Field CA (SPX) May 06, 2008Between three and four billion years ago, Mars was a lot like Earth. Both planets are believed to have had surface water. Those similarities make it a prime candidate for extraterrestrial life. "The assumption is that if bacterial life emerged on Earth at that time, then why not on Mars?" says Soon Sam Kim, principal member of technical staff at NASA's Jet Propulsion Laboratory. Mars may a ... more Spirit In A Catch-22: Stay Awake Or Sleep 
Pasadena CA (SPX) May 06, 2008Spirit's Tau measurements of atmospheric dust have remained steady, but solar array input has dropped a bit to 235 watt-hours per sol. Spirit still has enough energy to squeeze in Moessbauer studies of iron-bearing minerals at a time of year when the rover's handlers expected Spirit to be concerned only with survival. At present, the rover's target of scientific interest is a soil exposure ... more Glaciers Reveal Martian Climate Has Been Recently Active 
Providence RI (SPX) Apr 30, 2008The prevailing thinking is that Mars is a planet whose active climate has been confined to the distant past. About 3.5 billion years ago, the Red Planet had extensive flowing water and then fell quiet - deadly quiet. It didn't seem the climate had changed much since. Now, in a research article that graces the May cover of Geology, scientists at Brown University think Mars' climate has ... more |

Pasadena CA (SPX) Apr 25, 2008A small motor in the robotic arm of NASA's Mars Exploration Rover Opportunity that began stalling occasionally more than two years ago has become more troublesome recently. Rover engineers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., are diagnosing why the motor, one of five in the robotic arm, stalled on April 14 after much less motion that day than in the case of several earlier stal ... more Spirit Still Sitting Pretty For This Time Of Year 
Pasadena CA (JPL) Apr 23, 2008Despite a slight increase in atmospheric opacity caused by dust, Spirit is still enjoying higher-than-expected energy levels for this time of year. Solar array input has been approximately 240 watt-hours per Martian day, or sol (100 watt-hours is the amount of energy needed to light a 100-watt bulb for one hour). Clear skies have had the unfavorable effect, however, of causing a drop in ... more Driving on Mars Is Hard 
Pasadena CA (JPL) Apr 23, 2008This week Opportunity demonstrated the challenges of operating a vehicle on the surface of another planet. The rover is en route to Cape Verde to acquire high-resolution images of the layering in the rocks. To get there, Opportunity must cross some sandy stretches. Before entering the sandy areas, Opportunity will need to stop and take a "toe dip'' -- that is, drive forward a short distance and ... more |

Miami (AFP) April 18, 2008NASA wants astronauts who will return to the moon to take one long step for mankind. The US space agency hopes to build moon bases that can house astronauts for stays of up to six months, with an intricate transportation and power system, Carl Walz, director of NASA's Advanced Capabilities Division, said Friday. NASA is examining different designs for lunar outposts but that they could b ... more Mars Radar Opens Up A Planet's Third Dimension 
Paris, France (SPX) Apr 18, 2008ESA's Mars Express radar sounder, MARSIS, has looked beneath the martian surface and opened up the third dimension for planetary exploration. The technique's success is prompting scientists to think of all the other places in the Solar System where they would like to use radar sounders. No matter how accurate a camera is, it can only map a planet's surface. To retrieve information about th ... more Russia To Create Manned Assembly Complex In Orbit 
Moscow (XNA) Apr 14, 2008Russia is going to create a manned assembly complex in orbit, the chief of the Federal Space Agency Anatoly Perminov said here on Saturday. "We shall create this complex in order to make dockings in orbit, build craft there and send them to the Moon, Mars and other planets," Perminov was quoted by the Itar-Tass news agency as telling a new briefing. "This proposal was on the wh ... more Russia Continues Flight Simulation Experiments For Mars-500 
Moscow (RIA Novosti) Apr 16, 2008Four volunteers will spend ten days in a compression chamber with a reduced oxygen level as preparation for Mars-500, a Russian ground-based experiment to simulate a flight to Mars. A spokesman for the Moscow-based Russian Institute of Medical and Biological Issues, which runs the project, said that four healthy men will be held in a chamber with the pressure equivalent to being five meters ... more
