Move On To Mars
Moffett Field CA (SPX) May 15, 2009Science fiction writers have long imagined a future for humans on Mars, and Hollywood has created several movie fantasies about what the experience could be like (with a few improbable aliens added for extra drama). NASA has addressed the possibility of creating human colonies on Mars someday, but so far, only robots have stepped foot on the red soil. How long will we have to wait for scie ... more Spirit rover stuck in Martian soil: NASA 
Los Angeles (AFP) May 12, 2009NASA's Spirit rover, which has been exploring Mars for evidence of water, has gotten stuck, perhaps inextricably, in the soft Martian soil, said officials from NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. "Spirit is in a very difficult situation. We are proceeding methodically and cautiously," JPL's John Callas, project manager for Spirit and its twin rover, Opportunity, s ... more Soft Ground Puts Mars Rover Spirit In Danger 
Pasadena CA (SPX) May 12, 2009The five wheels that still rotate on NASA's Mars Exploration Rover Spirit have been slipping severely in soft soil during recent attempts to drive, sinking the wheels about halfway into the ground. The rover team of engineers and scientists has suspended driving Spirit temporarily while studying the ground around the rover and planning simulation tests of driving options with a test rover ... more Hubble: a time machine that revolutionized astronomy 
Washington (AFP) May 9, 2009The Hubble space telescope, the object of NASA's fifth and last servicing mission next week, is a veritable time machine that has revolutionized humankind's vision and comprehension of the universe. Put into orbit at an altitude of 600 kilometers (360 miles) by the shuttle Discovery on April 25, 1990, Hubble has transmitted more than 750,000 spectacular images and streams of data from the en ... more Obama orders review of NASA's shuttle replacement 
Washington (AFP) May 7, 2009President Barack Obama on Thursday ordered a review of a problem-plagued rocket that NASA hopes will replace its shuttle fleet, but the agency insisted the future of manned US space flights was safe. "NASA will review US post-shuttle human space flight activities this summer," Obama's new budget said, sparking questions over the future of the Constellation project and its ambition to take ... more |

Washington DC (SPX) May 05, 2009NASA has selected two science investigations that will aid in the interior examination of Mars and probe the tenuous atmosphere of Mercury. The projects, valued at approximately $38 million, also establish new alliances with the European Space Agency, or ESA. "The selections will further advance our knowledge of these exciting terrestrial planets," said Jim Green, director of NASA's ... more Focused On Phobos 
Moffett Field CA (SPX) May 04, 2009Efforts to reach the martian moon Phobos have long been outshined by missions to the Red Planet itself. Now, scientists in Russia, Canada and the U.S. are preparing their own missions to the largest moon of Mars. Mars actually has two moons: Phobos and Deimos. They might more properly be called satellites, however, because they are extremely small, only a few kilometers in diameter. ... more Spirit problems still baffle scientists
Washington, April 27, 2009 U.S. space agency scientists say they have not yet solved the mysterious cause of several glitches in the Mars exploration rover Spirit. National Aeronautics and Space Administration engineers remotely drove Spirit Thursday for the first time since April 8 while investigating bouts of amnesia and other unusual behavior exhibited by the rover this month. Spirit has already operate ... more Spirit Resumes Driving While Analysis Of Problem Behaviors Continues 
Pasadena CA (JPL) Apr 27, 2009NASA's Mars Exploration Rover Spirit drove on Thursday for the first time since April 8, acting on commands from engineers who are still investigating bouts of amnesia and other unusual behavior exhibited by Spirit in the past two weeks. The drive took Spirit about 1.7 meters (5.6 feet) toward destinations about 150 meters (about 500 feet) away. The rover has already operated more than 20 ... more |

Tucson, Arizona (AFP) April 15, 2009Astronauts' meals have come a long way from the freeze-dried powders and semi-liquid pastes of decades ago: now US scientists want to grow vegetables in mini-greenhouses on the Moon. Although space fare has steadily improved over time, a team of scientists says the best is yet to come. They look forward to when residents of future lunar or even Martian outposts can dine on luxuries such ... more Spirit Healthy But Computer Reboots Raise Concerns 
Pasadena CA (SPX) Apr 14, 2009The team operating NASA's Mars Exploration Rover Spirit is examining data received from Spirit in recent days to diagnose why the rover apparently rebooted its computer at least twice over the April 11-12 weekend. "While we don't have an explanation yet, we do know that Spirit's batteries are charged, the solar arrays are producing energy and temperatures are well within allowable ranges. ... more Cleaning Event Boosts Energy For Mars Rover Opportunity 
Pasadena CA (JPL) Apr 14, 2009On Sol 1845 (April 2, 2009), the rover's robotic arm (IDD) placed the Mossbauer (MB) spectrometer on the outcrop target "Penrhyn" for a multi-sol integration. On Sol 1850 (April 7, 2009), a temporary stand-down on driving was provisionally lifted and Opportunity resumed driving. The MB was retracted and the arm moved into the driving stow position. Opportunity then drove backward about 62. ... more Pratt And Whitney Rocketdyne Tests Propulsion Technology 
Canoga Park CA (SPX) Apr 08, 2009Pratt and Whitney Rocketdyne completed a series of successful hot-fire tests for a propulsion system that could lead to increased mission capability and flexibility in sending humans to the moon, Mars and beyond. During the tests at NASA's Glenn Research Center in Cleveland, Ohio, a 25 pound-force thruster testbed successfully demonstrated cooling with gaseous methane and gaseous oxygen, a ... more
