Clocks 'failed' onboard Europe's navigation satellites: ESA
Paris (AFP) Jan 18, 2017 - Europe's beleaguered Galileo satnav has suffered another setback, with clocks failing onboard a number of satellites in space, the European Space Agency said Wednesday. Designed to render Europe independent from America's GPS, the 10 billion-euro ($11 billion) project may experience further delays as the cause of the failure is investigated, ESA director general Jan Woerner told journalists in Paris. ... more

Mars Rover Curiosity Examines Possible Mud Cracks
Pasadena CA (JPL) Jan 18, 2017 - Scientists used NASA's Curiosity Mars rover in recent weeks to examine slabs of rock cross-hatched with shallow ridges that likely originated as cracks in drying mud. "Mud cracks are the most likely scenario here," said Curiosity science team member Nathan Stein. He is a graduate student at Caltech in Pasadena, California, who led the investigation of a site called "Old Soaker," on lower M ... more

Opportunity Continues Its Journey South Along Crater Rim
Pasadena CA (JPL) Jan 18, 2017 - Opportunity is located on the rim of Endeavour Crater, heading south along the rim. The near-term plan is to reach a valley called 'Willamette' where grooves are seen in orbital imagery. The rover had recently disturbed the surface soil during a challenging uphill drive and revealed some interesting bright material. The science team saw this as an opportunity to conduct some long ove ... more

Successful Deep Space Maneuver for NASA's OSIRIS-REx Spacecraft
Greenbelt MD (SPX) Jan 18, 2017 - New tracking data confirms that NASA's OSIRIS-REx spacecraft aced its first Deep Space Maneuver (DSM-1) on Dec. 28, 2016. The engine burn sets up the spacecraft for an Earth gravity assist this fall as it continues its two-year journey to the asteroid Bennu. The large maneuver was the first using OSIRIS-REx's main engines and resulted in a 964 miles per hour (431 meters per second) change ... more

Probable cause and potential prevention of vision deterioration in space found
Dallas TX (SPX) Jan 18, 2017 - Vision deterioration in astronauts who spend a long time in space is likely due to the lack of a day-night cycle in intracranial pressure. But using a vacuum device to lower pressure for part of each day might prevent the problem, UT Southwestern Medical Center researchers said. Their study appears in the Journal of Physiology. A change in vision is the No. 1 health risk for astronauts who ... more

Iridium-1 NEXT Launched on a Falcon 9
Bethesda MD (SPX) Jan 18, 2017 - SpaceX has successfully launched 10 satellites for Iridium Communications. This was the first of several such launches in the Iridium satellite replacement program. Many are calling this program a "tech refresh" and it may be the biggest of its kind in history. This was also a historical event for SpaceX's Falcon 9 rocket, because this is the first launch since an explosion occurred last f ... more

China's first cargo spacecraft to leave factory
Beijing (XNA) Jan 18, 2017 - China's first cargo spacecraft will leave the factory, according to the website of China's manned space mission. A review meeting was convened last Thursday, during which officials and experts unanimously concluded that the Tianzhou-1 cargo spacecraft had met all the requirements to leave the factory. The take-off weight of Tianzhou-1 is 13 tonnes and it can ship material of up to si ... more

Presumed young star turns out to be a galactic senior citizen
Bochum, Germany (SPX) Jan 18, 2017 - 49 Lib, a relatively bright star in the southern sky, is twelve billion years old rather than just 2.3 billion. For many decades, researchers were stumped by conflicting data pertaining to this celestial body, because they had estimated it as much younger than it really is. Determining its age anew, astronomers at Ruhr-Universitat Bochum (RUB) have now successfully resolved all inconsistencies. ... more

Galaxy murder mystery
Perth, Australia (SPX) Jan 18, 2017 - It's the big astrophysical whodunnit. Across the Universe, galaxies are being killed and the question scientists want answered is, what's killing them? New research published by a global team of researchers, based at the International Centre for Radio Astronomy Research (ICRAR), seeks to answer that question. The study reveals that a phenomenon called ram-pressure stripping is more prevale ... more

NASA Glenn RED Team Helps EP+R Sterilize Ambulances
Cleveland OH (SPX) Jan 18, 2017 - When a small business in Kent, Ohio was looking for help to advance one of their products, it came from an unexpected source. Emergency Products and Research (EP+R) designs and manufactures emergency medical products, such as straps, backboards/spineboards and rescue vests. In 2014, the firm saw a critical need in the industry to decontaminate and sterilize ambulance interiors between pati ... more

ALMA starts observing the sun
Munich, Germany (SPX) Jan 18, 2017 - New images taken with the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile have revealed otherwise invisible details of our Sun, including a new view of the dark, contorted centre of a sunspot that is nearly twice the diameter of the Earth. The images are the first ever made of the Sun with a facility where ESO is a partner. The results are an important expansion of the range o ... more

Deep mantle chemistry surprise: Carbon content not uniform
Washington DC (SPX) Jan 17, 2017 - Even though carbon is one of the most-abundant elements on Earth, it is actually very difficult to determine how much of it exists below the surface in Earth's interior. Analysis by Carnegie's Marion Le Voyer and Erik Hauri of crystals containing completely enclosed mantle magma with its original carbon content preserved has doubled the world's known finds of mantle carbon. The findings are publ ... more

Seeing the quantum future literally
Sydney, Australia (SPX) Jan 17, 2017 - Scientists at the University of Sydney have demonstrated the ability to "see" the future of quantum systems, and used that knowledge to preempt their demise, in a major achievement that could help bring the strange and powerful world of quantum technology closer to reality. The applications of quantum-enabled technologies are compelling and already demonstrating significant impacts - espec ... more

Scientists proposed a novel regional path tracking scheme for autonomous ground vehicles
Beijing, China (SPX) Jan 17, 2017 - For autonomous ground vehicles (AGVs), one of the most important issues is path tracking. Conventionally, steering and velocity control are generally two typical aspects in path tracking problem. Steering control is discussed in this manuscript because it is important to path tracking and related to vehicle lateral stability. Most of the existing algorithms are developed based on point-line vehi ... more
