Mud Volcanoes On MarsMoffett Field CA (SPX) Aug 20, 2010 If life does - or did - exist on Mars, signs of such life might well be found in a region in the northern plains called Acidalia Planitia, according to a new study. The region appears to be dotted with what scientists believe are geological structures known as mud volcanoes, spewing out muddy sediments from underground. These sediments might contain organic materials that could be biosignatures of possible past and present life. "If there was life on Mars, it probably developed in a fluid-ri ... read more |

Paris, France (SPX) Aug 19, 2010Using ESO's Very Large Telescope, European astronomers have for the first time demonstrated that a magnetar - an unusual type of neutron star - was formed from a star with at least 40 times as much mass as the Sun. The result presents great challenges to current theories of how stars evolve, as a star as massive as this was expected to become a black hole, not a magnetar. This now raises a ... more  
Boston MA (SPX) Aug 19, 2010Although unmanned, wheeled rovers have explored the surfaces of the moon and Mars for decades, these vehicles have limits - they can't crawl inside craters, scale cliffs or travel long distances. For more than two years, a team of students led by Professor of the Practice of Astronautics and former NASA astronaut Jeffrey Hoffman in MIT's Department of Aeronautics and Astronautics has been ... more  
Moffett Field CA (SPX) Aug 19, 2010Since its October 2008 launch, NASA's Interstellar Boundary Explorer (IBEX) spacecraft has mapped the invisible interactions occurring at the edge of the solar system. The images reveal that the interactions between our home in the galaxy and interstellar space are surprisingly structured and intense. IBEX provides global imaging of the interstellar boundary much like a weather satellite p ... more |

End-to-End Ballistic Missile Defense System Simulation CompletedColorado Springs CO (SPX) Aug 20, 2010 The U.S. Missile Defense Agency (MDA) and Northrop Grumman Corporation have finalized verification and validation of the Ballistic Missile Defense System (BMDS) Performance Assessment 2009 (PA09). PA09 is an end-to-end system-level simulation conducted to analyze how the BMDS integrated radars, communication networks and interceptors perform during scenarios. Northrop Grumman, as the prime contractor at the Missile Defense Integration and Operations Center (MDIOC) under the Joint National Integrat ... read more |
