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 New dinner table top priority as ISS expands 
Star City, Russia (AFP) May 7, 2009Astronauts set to blast off for the International Space Station said Thursday that constructing a new dinner table would be a top priority as its permanent crew expands to six. The three-man crew will travel into orbit on a Soyuz capsule later this month, joining an existing three-person team on the ISS and for the first time raising its permanent crew to six. "We are now going to have ... more NASA, ESA And A Trip To Mars 
Moffett Field CA (SPX) May 08, 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 Planet ... more |

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 Bone-Density Monitor Would Let Astronauts Test While In Space 
Houston TX (SPX) Apr 24, 2009It would be terrible if the first humans to reach Mars stepped onto the surface to discover their legs could no longer hold them. A team of Rice University students is working to make sure that doesn't happen. Five senior bioengineering students have designed a device to help astronauts keep their skeletons strong and healthy by measuring bone mineral density loss, literally on the fly. ... more Early Martian Environment And Water Drive Search For Life Forms 
New Rochelle (SPX) Apr 17, 2009Solar energy and winds, collisions with asteroids and comets, and changing magnetic fields have all altered the environment of Mars, a planet that may have been able to support life during its history, as documented in a special collection of papers published in the current issue of Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. Compiled by Helmut Lammer, PhD, Se ... more |

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 Spirit Sets Distance Record For Five-Wheel Driving 
Pasadena CA (SPX) Apr 04, 2009Spirit is making good progress around Home Plate to the west. After getting clear of troublesome rocks, Spirit drove 13.8 meters (45.3 feet) on Sol 1854 (March 21, 2009). The next drive, on Sol 1856 (March 23, 2009) , achieved a new distance record for five-wheel driving. Spirit drove 25.82 meters (84.7 feet), beating the old record by about a meter. Spirit completed another drive of ... more Opportunity Brushing and Examining an Outcrop 
Pasadena CA (SPX) Apr 04, 2009Opportunity remains positioned on an exposed rock outcrop, continuing an "in situ" (contact) science campaign with the robotic arm (IDD). On Sol 1832 (March 20, 2009), the first part of a rock abrasion tool (RAT) brushing activity was performed. Using a new work-around for the failed RAT Z-encoder, the RAT successfully performed a seek-scan to locate the rock surface. On the next sol ... more
