NASA television broadcast live images of the crew inside the ISS as the capsule was installed on the Earth-facing port of the Harmony module, a US-built utility hub, at 1406 GMT. It said the capsu ... more |  |
 Odd Tilts Could Make More Worlds Habitable Greenbelt MD (SPX) Apr 19, 2014 - Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according to new modeling by NASA and university scientists affiliated with the NASA Astrobiology Institute. The climate effects generated on these wobbling worlds could prevent them from turning into glacier-covered ice lockers, even if those planets are so ... more |  |
 Go Big or Go Home - Shuttle Carrier Aircraft Doing Both, and More Houston TX (SPX) Apr 19, 2014 - The space shuttle orbiter mock-up has been a lonesome bird at Space Center Houston, Johnson Space Center's official visitor center, waiting for its permanent piggyback ride atop NASA 905. But at the end of April, that wait will finally be over as NASA's oldest modified commercial airliner, a Boeing 747 dubbed NASA 905, makes its way through Clear Lake with all the nonchalance of a rhinoceros per ... more |  |
 Astronauts Prep for Spacewalk as Mission Managers Evaluate Busy Schedule Houston TX (SPX) Apr 19, 2014 - The astronauts of the International Space Station's Expedition 39 crew focused Tuesday on preparations for a contingency spacewalk to be conducted in the next week or so.

 Searching for dark energy with neutrons Vienna, Austria (SPX) Apr 19, 2014 - All the particles we know to exist make up only about five per cent of the mass and energy of the universe. The rest - "Dark Matter" and "Dark Energy" - remains mysterious. A European collaboration lled by researchers from the Vienna University of Technology has now carried out extremely sensitive measurements of gravitational effects at very small distances at the Institut Laue-Langevin (ILL) i ... more |  |

A study in scarlet Munich, Germany (SPX) Apr 19, 2014 - This area of the southern sky, in the constellation of Centaurus (The Centaur), is home to many bright nebulae, each associated with hot newborn stars that formed out of the clouds of hydrogen gas. The intense radiation from the stellar newborns excites the remaining hydrogen around them, making the gas glow in the distinctive shade of red typical of star-forming regions. Another famous ex ... more |  |
MEASAT-3b arrives in French Guiana; Ariane 5 delivered to Kourou Kourou, French Guiana (ESA) Apr 19, 2014 - Payload preparations for Arianespace's next Ariane 5 mission are gearing up following this week's delivery of MEASAT-3b - one of two satellite passengers for launch on the heavy-lift flight - to French Guiana. This spacecraft was transported by a chartered An-124 cargo jetliner that landed at Felix Eboue International Airport near the capital city of Cayenne, and was unloaded for its trans ... more |  |

The latest generation of inReach will be available in stores in early May and builds on DeLorme's award-winning technology to keep outdoor adventurers, offshore boaters, hunters, aviators, travelers and workers connected wherever they go. In addition to the ... more |  |
 NASA Mars Orbiter Spies Rover Near Martian Butte Pasadena CA (JPL) Apr 19, 2014 - Scientists using NASA's Curiosity Mars rover are eyeing a rock layer surrounding the base of a small butte, called "Mount Remarkable," as a target for investigating with tools on the rover's robotic arm. The rover works near this butte in an image taken on April 11 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. A rover's-eye v ... more |  |
Meteorites Yield Clues to Red Planet's Early Atmosphere College Park MD (SPX) Apr 19, 2014 - Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks. Their study, published April 17 in the journal Nature, shows that the atmospheres of Mars and Earth diverged in important ways very early in the 4.6 billion year evolution of our solar system. The results will help guide res ... more |  |

 New Study Outlines 'Water World' Theory of Life's Origins Pasadena CA (JPL) Apr 19, 2014 - Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet's living kingdoms. How did it all begin? A new study from researchers at NASA's Jet Propulsion Laboratory in Pasadena, Cal ... more |  |
B3: the vitamin from outer space Greenbelt, Md. (UPI) Apr 18, 2013 - Vitamin B3, also called nicotinic acid or niacin, is the precursor to nicotinamide adenine dinucleotide (NAD) - vital to metabolism and a key to the development of ancient life. And though its possible B3 developed non-biologically on ancient Earth, scientists say it's likely carbon-rich meteorites peppering the planet millions of years ago offered an extra dose of niacin. In studying ... more |  |
 Tech giants look to skies to spread Internet New York (AFP) April 16, 2014 - The shortest path to the Internet for some remote corners of the world may be through the skies. That is the message from US tech giants seeking to spread the online gospel to hard-to-reach regions. Google took a step in that direction this week with the acquisition of Titan Aerospace, a maker of solar-powered drones that can help boost Internet access to remote areas. "It's still ea ... more |  |
 Scientists Capture Ultrafast Snapshots of Light-Driven Superconductivity Upton NY (SPX) Apr 17, 2014 - A new study pins down a major factor behind the appearance of superconductivity-the ability to conduct electricity with 100 percent efficiency-in a promising copper-oxide material. Scientists used carefully timed pairs of laser pulses at SLAC National Accelerator Laboratory's Linac Coherent Light Source (LCLS) to trigger superconductivity in the material and immediately take x-ray snapshot ... more |  |
 "RoboClam" hits new depths as robotic digger London, UK (SPX) Apr 17, 2014 - A digging robot inspired by the unique mechanisms employed by the Atlantic razor clam has been created by a group of researchers in the US.
