 Space station cooling breakdown may delay Orbital launch Washington (AFP) Dec 12, 2013 - NASA rushed Thursday to fix a breakdown in the cooling system at the International Space Station that may delay the launch next week of Orbital Sciences' first cargo mission. Engineers are still trying to figure out what caused the fault Wednesday in a flow valve that controls the temperature of the equipment aboard the station, said mission team manager Kenny Todd. The astronauts on boa ... more |  |
 Chinese flyby of asteroid shows space rock is "rubble" Paris (AFP) Dec 12, 2013 - China's first flyby of an asteroid shows that a gigantic space rock which once triggered a doomsday scare is essentially rubble, scientists reported on Thursday. On December 13 2012, a lunar probe called Chang'e-2 rendezvoused with asteroid 4179 Toutatis as the rock, bigger than a city block, swept by Earth at a distance of around seven million kilometres (4.4 million miles). Describing ... more |  |

 Hard rock life East Lansing MI (SPX) Dec 13, 2013 - Scientists are digging deep into the Earth's surface collecting census data on the microbial denizens of the hardened rocks. What they're finding is that, even miles deep and halfway across the globe, many of these communities are somehow quite similar. The results, which were presented at the American Geophysical Union conference, suggest that these communities may be connected, said Matt ... more |  |
NASA Curiosity: First Mars Age Measurement and Human Exploration Help Pasadena CA (JPL) Dec 13, 2013 - NASA's Curiosity rover is providing vital insight about Mars' past and current environments that will aid plans for future robotic and human missions.

Sir Martin Sweeting, Executive Chairman of SSTL said: "SSTL believes that the commercialisation of space exploration is vital in order to bring down costs and schedules an ... more |  |
Countdown Begins for NASA's OSIRIS-REx Asteroid Mission Greenbelt MD (SPX) Dec 13, 2013 - NASA's OSIRIS-REx asteroid sample return mission began its countdown on December 9, at 7:43 PM EST, with 999 days remaining until the opening of the mission's launch window in September 2016. "This is a pioneering effort, both technologically and scientifically," said Dante Lauretta, OSIRIS-Rex principal investigator from the University of Arizona, Tuscon. "Starting the countdown clo ... more |  |
 Chang'e-3 probe moves closer to the moon Beijing (XNA) Dec 13, 2013 - China's lunar probe Chang'e-3 entered an orbit closer to the moon on Tuesday night. Following an order from the Beijing Aerospace Control Center, the probe descended from the 100 km-high lunar circular orbit to an elliptical orbit with its nearest point about 15 km away from the moon's surface, the State Administration of Science, Technology and Industry for National Defense said in a stat ... more |  |

 New Video Reveals NASA's Webb Telescope is "All Sewn Up" Greenbelt MD (SPX) Dec 13, 2013 - The newest video in the "Behind the Webb" series takes viewers behind the scenes to reveal how the pieces that make up each layer of the James Webb Space Telescope's thin sunshield are bonded together. NASA's Webb telescope has a five-layer sunshield that is as large as a tennis court. The sunshield will help keep the infrared instruments aboard as cold as possible by blocking out heat and ... more |  |
Fire vs. Ice: The Science of ISON at Perihelion Greenbelt MD (SPX) Dec 13, 2013 - After a year of observations, scientists waited with bated breath on Nov. 28, 2013, as Comet ISON made its closest approach to the sun, known as perihelion. Would the comet disintegrate in the fierce heat and gravity of the sun? Or survive intact to appear as a bright comet in the pre-dawn sky? Some remnant of ISON did indeed make it around the sun, but it quickly dimmed and fizzled as see ... more |  |
Mars One Selects Lockheed Martin to Study First Private Unmanned Mission to Mars Denver CO (SPX) Dec 13, 2013 - Mars One has selected Lockheed Martin to develop a mission concept study for its Mars lander spacecraft. The lander will be based on the successful 2007 NASA Phoenix spacecraft and will be a technology demonstrator. Slated for a 2018 launch, the mission will provide proof of concept for some of the technologies that are important for a permanent human settlement on Mars; the ultimate goal ... more |  |
 Johns Hopkins APL Will Launch RAVAN Cubesat to Help Solve an Earth Science Mystery Laurel MD (SPX) Dec 13, 2013 - A new, low-cost cubesat mission led by the Johns Hopkins Applied Physics Laboratory in Laurel, Md. will demonstrate technology needed to measure the absolute imbalance in the Earth's radiation budget for the first time, giving scientists valuable information to study our climate.

 CU-Boulder scientist: 2012 solar storm points up need for society to prepare Boulder CO (SPX) Dec 13, 2013 - A massive ejection of material from the sun initially traveling at over 7 million miles per hour that narrowly missed Earth last year is an event solar scientists hope will open the eyes of policymakers regarding the impacts and mitigation of severe space weather, says a University of Colorado Boulder professor. The coronal mass ejection, or CME, event was likely more powerful than the fam ... more |  |

 Ancient crater could hold clues about moon's mantle Providence RI (SPX) Dec 13, 2013 - Researchers from Brown University and the University of Hawaii have found some mineralogical surprises in the Moon's largest impact crater. Data from the Moon Mineralogy Mapper that flew aboard India's Chandrayaan-1 lunar orbiter shows a diverse mineralogy in the subsurface of the giant South Pole Aitken basin. The differing mineral signatures could be reflective of the minerals dredged up ... more |  |
NASA reports coolant loop problem at ISS Washington (AFP) Dec 12, 2013 - NASA reported a problem Wednesday at the International Space Station but said the crew was not in any danger. One of two large coolant loops at the ISS - on which electrical systems ride - shut down earlier in the day, Josh Byerly, a spokesman for the US space agency, told AFP.

Scientist: Near-miss solar storm should be a wake-up call Boulder, Colo. (UPI) Dec 10, 2013 - A massive solar storm that narrowly missed Earth last year should open the eyes of policymakers to the threat of severe space weather, a U.S. scientist says. The coronal mass ejection traveling at more than 7 million miles per hour was likely more powerful than the famous Carrington storm of 1859 that blasted Earth's atmosphere so hard it kit up they skies with auroras from the North Po ... more |  |
 Feature of Earth's atmosphere may help in search for habitable planets Seattle (UPI) Dec 10, 2013 - An atmospheric peculiarity on Earth is likely common to billions of planets, a finding that may help identify potentially habitable worlds, U.S. scientists say. While our atmosphere generally gets colder and thinner with altitude, there's a point at about 40,000 to 50,000 feet where it stops cooling and begins growing warmer, a phenomenon found not only on Earth but also on Jupiter, Sat ... more |  |
