Chang'e-3 satellite payload APXS obtained its first spectrum of lunar regolith
Beijing, China (SPX) Jan 03, 2014 - The Active Particle-induced X-ray Spectrometer (APXS), carried by the Yutu rover of the Chang'e-3 satellite got its first X-ray fluorescence spectrum of lunar regolith around the landing site on December 25, 2013. An initial analysis indicates that eight major rock-forming elements (Mg, Al, Si, K, Ca, Ti, Cr and Fe) and at least 3 minor elements (Sr, Y and Zr) of the Moon can be identified ... more

Wall-Crawling Gecko Robots Can Stick In Space Too
Paris (ESA) Jan 03, 2014 - Climbing robots that mimic the stickiness of gecko lizard feet could work in space as well as on Earth, ESA has shown, raising the prospect of hull-crawling automatons tending future spacecraft. Robots crawling across spacecraft surfaces are a common sight in science fiction films from Silent Running to Wall-E. But, in reality, how might they stick in place while still remaining mobile? ... more

More than 1,000 chosen for one-way Mars reality-TV mission
The Hague (AFP) Jan 02, 2014 - More than 1,000 candidates - from 200,000 hopefuls - have been chosen to train for a private Mars colonisation mission to be partly funded by a reality-TV show following their training and subsequent steps, organisers said Thursday. They are to be whittled down to just 24, who will be sent over six launches starting in 2024, according to Mars One, the Dutch-based non-profit group behind th ... more

NASA's Hubble Sees Cloudy Super-Worlds With Chance for More Clouds
Baltimore MD (SPX) Jan 01, 2014 - Scientists using NASA's Hubble Space Telescope have characterized the atmospheres of two of the most common type of planets in the Milky Way galaxy and found both may be blanketed with clouds. The planets are GJ 436b, located 36 light-years from Earth in the constellation Leo, and GJ 1214b, 40 light-years away in the constellation Ophiuchus. Despite numerous efforts, the nature of the atmo ... more

Two Solar Flares Say Goodbye 2013 and Welcome 2014
Greenbelt MD (SPX) Jan 03, 2014 - The sun ushered out 2013 and welcomed 2014 with two mid-level flares on Dec. 31, 2013 and Jan. 1, 2014. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however - when intense enough - they can disturb the atmosphere in the layer where GPS and communications signals travel. ... more

First Asteroid Discovered in 2014 Has Little Impact
Pasadena CA (JPL) Jan 03, 2014 - Early Wednesday morning January 1st, while New Year's 2014 celebrations were still underway in the United States, the Catalina Sky Survey near Tucson, AZ, collected a single track of observations with an immediate follow-up on what was possibly a very small asteroid 2-3 meters in size on a potential impact trajectory with the Earth. Designated 2014 AA, which would make it the first asteroi ... more

MAM produces plasma cavity for Helicon Double Layer Thruster Engine
Berkshire, UK (SPX) Jan 03, 2014 - Morgan Advanced Materials has provided a prototype plasma cavity for the Helicon Double Layer Thruster (HDLT), a new gas plasma space engine for use on satellites being developed by the Australian National University (ANU). Gas plasma engines are used in electric propulsion, a technology becoming more and more popular, because it uses "greener" propellants, rather than more toxic chemicals. ... more

Watch the 2014 Quadrantid Meteor Shower Live on Ustream
Huntsville AL (SPX) Jan 03, 2014 - Peaking in the wee hours of Jan. 3, a little-known meteor shower named after an extinct constellation, the Quadranids, will present an excellent chance for hardy souls to start the year off with some late-night meteor watching. The Quadrantids have a maximum rate of about 80 per hour, varying between 60-200. The very young moon will set early, presenting an excellent opportunity for meteor ... more

New Studies Give Strong Boost to Binary-Star Formation Theory
Charlottesville VA (SPX) Jan 01, 2014 - Using the new capabilities of the upgraded Karl G. Jansky Very Large Array (VLA), scientists have discovered previously-unseen binary companions to a pair of very young protostars. The discovery gives strong support for one of the competing explanations for how double-star systems form. Astronomers know that about half of all Sun-like stars are members of double or multiple-star systems, b ... more

Dawn passes halfway mark to Ceres
Pasadena CA (JPL) Jan 03, 2014 - Now more than halfway through its journey from protoplanet Vesta to dwarf planet Ceres, Dawn is continuing to use its advanced ion propulsion system to reshape its orbit around the sun. Now that the ship is closer to the uncharted shores ahead than the lands it unveiled astern, we will begin looking at the plans for exploring another alien world. In seven logs from now through August, we w ... more

More BARREL Balloons Take to the Skies
Greenbelt MD (SPX) Jan 03, 2014 - The second year of an unprecedented balloon campaign in Antarctica has just begun. The NASA-funded mission - called the Balloon Array for Radiation belt Relativistic Electron Losses, or BARREL - is led by Dartmouth College in Hanover, N.H. The mission is unique, as it relies not on one gigantic balloon, but on many smaller ones, 20 in total. BARREL's job is to help unravel the mysterious r ... more

Geckos in space: Novel robot takes a step to cosmos
Paris (AFP) Jan 02, 2014 - A wall-crawling robot inspired by the gecko has taken a small but important step towards a future in space, scientists said on Thursday. The tiny legged prototype could be the forerunner of automatons which crawl along the hulls of spacecraft, cleaning and maintaining them, the European Space Agency (ESA) said. Its footpads are covered with dry microfibres modelled on the toe hair of the ... more

China to upgrade homegrown GPS to improve accuracy
Beijing (UPI) Dec 30, 2013 - China says it will have 30 satellites in its Beidou navigation system by 2020 to improve accuracy to within inches to better compete with the U.S.GPS. The Beidou network, with 16 satellites serving the Asia-Pacific region, currently has an accuracy of about 15 feet but Chinese officials say they want to upgrade it to compete with the U.S. global positioning system, the most widely used ... more

Large-aperture planar lens antennas with gradient refractive index
Beijing, China (SPX) Jan 01, 2014 - It was recently shown that large-aperture lens antennas can be designed by using gradient-index (GRIN) metamaterials and that higher directivity and gain can be obtained than with traditional dielectric lens antennas. This provides an effective method to design high-performance lens antennas. A paper titled "Three-dimensional large-aperture lens antennas with gradient refractive index," pu ... more

Moscow (Voice of Russia) Jan 01, 2014 - The sun has undergone a "complete field reversal," with its north and south poles changing places as it marks the midpoint of Solar Cycle 24. "A reversal of the sun's magnetic field is, literally, a big event," NASA's Dr. Tony Phillips said in a statement issued on the space agency's website. "The sun's polar magnetic fields weaken, go to zero and then emerge again with the opposite ... more

Earth's crust was unstable in the Archean eon and dripped down into the mantle
Mainz, Germany (SPX) Dec 31, 2013 - Earth's mantle temperatures during the Archean eon, which commenced some 4 billion years ago, were significantly higher than they are today. According to recent model calculations, the Archean crust that formed under these conditions was so dense that large portions of it were recycled back into the mantle. This is the conclusion reached by Dr. Tim Johnson who is currently studying the evo ... more
