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 JPL Analyzing Spirit Computer Reboots And Amnesia Events 
Pasadena CA (JPL) Apr 21, 2009After three days of completing Earth-commanded activities without incident last week, NASA's Mars Exploration Rover Spirit had a bout of temporary amnesia Friday, April 17, and rebooted its computer Saturday, April 18, behavior similar to events about a week earlier. Engineers operating Spirit are investigating the reboots and the possibly unrelated amnesia events, in which Spirit unexpect ... more Opportunity For Some Crater Hopping On Route To Endeavour 
Pasadena CA (JPL) Apr 20, 2009Opportunity has been crater hopping as the rover heads south, making drives between several small craters and taking drive-by images of them. These small craters - just a few meters or yards in diameter - are from fairly recent impacts, occurring in the last, maybe, 10,000 to 100,000 years. Four drives were completed in the week, totaling more than 140 meters (459 feet). The drives ... more Spirit Suffers Memory Gaps and Unexplained Resets 
Pasadena CA (JPL) Apr 20, 2009Spirit failed to wake up for three planned events. The rover eventually woke up from an expiring alarm clock timer 27 hours later. Then, an unexpected reset of the rover occurred on Sol 1874 (April 11, 2009). A second reset occurred on Sol 1875 (April 12, 2009). It was also discovered that the rover did not record any data in flash memory on sols 1874 and 1876 (April 11 and April 13, 2009) ... 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 (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 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 |

Moscow (AFP) March 31, 2009The hatch slammed shut Tuesday behind six volunteers from Europe and Russia who will spend three months isolated in a capsule in Moscow to simulate conditions for a manned mission to Mars. The two Europeans and four Russians must now live in the cramped facility until the experiment ends 105 days later, allowing scientists to assess the effects of long duration space flight on their minds ... more Europe, Russia in Mars mission rehearsal 
Moscow (AFP) March 29, 2009Six volunteers from Europe and Russia will on Tuesday allow themselves to be locked up in a capsule in Moscow for over three months to simulate the conditions for an eventual manned mission to Mars. The two Europeans and four Russians will not be allowed to leave the facility until their mission ends 105 days later, allowing scientists to assess the psychological effects of long duration spa ... more US software tycoon makes space history 
Baikonur, Kazakhstan (AFP) March 26, 2009US software pioneer Charles Simonyi on Thursday became the first person to travel twice to space as a tourist, as he blasted off to the International Space Station (ISS). Simonyi, 60, along with an American and a Russian astronaut, was launched aboard a Russian Soyuz rocket at 11:49 GMT from the Baikonur cosmodrome on the Kazakh steppe, in what could be the last space tourist trip for some ... more Welcome To The Red Planet 
Moffett Field CA (SPX) Mar 27, 2009Did you ever wish you could stroll through the caldera of Olympus Mons, the largest volcano in the solar system? Study the rock formations in Valles Marineris, a martian canyon as wide as the United States? Or retrace the tracks of NASA's Spirit and Opportunity rovers? Then you'll want to check out Google Mars. Tucked away inside the recently released Google Earth 5.0, Google Mars is the i ... more
