U.S.-Russian crew reaches space station for year-long stay

ISS crew of Kelly of the U.S. and Kornienko and Padalka of Russia walk after donning space suits at the Baikonur cosmodromeBy Irene Klotz CAPE CANAVERAL, Fla (Reuters) - A Russian Soyuz rocket blasted off from the Baikonur Cosmodrome in Kazakhstan on Friday, sending a U.S.-Russia crew to the International Space Station for a year-long flight, a NASA Television broadcast showed. Four Soviet-era cosmonauts lived on the now-defunct Mir space station for a year or longer, but the missions, which concluded in 1999, did not have the sophisticated medical equipment that will be used during International Space Station investigations, NASA said.

Primordial sea creature with spiky claws unearthed in Canada

A freshly excavated fossil specimen of Yawunik kootenayi is seen in this undated handout pictureBy Will Dunham WASHINGTON (Reuters) - A fossil site in the Canadian Rockies that provides a wondrous peek into life on Earth more than half a billion years ago has offered up the remains of an intriguing sea creature, a four-eyed arthropod predator that wielded a pair of spiky claws. Scientists said on Friday they unearthed nicely preserved fossils in British Columbia of the 508 million-year-old animal, named Yawunik kootenayi, that looked like a big shrimp with a bad attitude and was one of the largest predators of its time. The fossil beds in Kootenay National Park where it was found were in a previously unexplored area of the Burgess Shale rock formation that for more than a century has yielded exceptional remains from the Cambrian Period, when many of the major animal groups first appeared. Yawunik, whose name honors a mythical sea monster in the native Ktunaxa people's creation story, was a primitive arthropod, the highly successful group that includes shrimps, lobsters, crabs, insects, spiders, scorpions, centipedes and millipedes.

Valeo's self-driving car systems learn from Safran drones

The new self-driving car unveiled by Valeo and Safran drives during a presentation in front of the Invalides in ParisBy Laurence Frost and Gilles Guillaume PARIS (Reuters) - French auto parts maker Valeo plans to draw on drone software and other military technologies from partner Safran to offer self-driving vehicle platforms to carmakers by the end of the decade. While demonstrating an autonomous car and other prototype systems jointly developed with Safran, the French defense and aerospace group, Valeo said on Friday the first applications may reach carmaker clients within three years. "We realized very quickly that we had much more in common than we'd expected," Valeo innovation chief Guillaume Devauchelle told Reuters. "It turns out that an autonomous vehicle is really a terrestrial drone." Cars that complete whole journeys without human input are still many years away, but creeping automation is well underway, with models already on sale that can pilot themselves through slow traffic and hit the brakes when a pedestrian steps out.

U.S. Air Force overstepped bounds in SpaceX certification: report

The unmanned Falcon 9 rocket lifts off from launch pad 40 the Cape Canaveral Air Force Station in Cape CanaveralBy Andrea Shalal WASHINGTON (Reuters) - The U.S. Air Force overstepped its bounds as it worked to certify privately held SpaceX to launch military satellites, undermining the benefit of working with a commercial provider, an independent review showed on Thursday. The report cited a "stark disconnect" between the Air Force and SpaceX, or Space Exploration Technologies, about the purpose of the certification process and recommended changes. Air Force Secretary Deborah James ordered the review after the service missed a December deadline for certifying SpaceX to compete for some launches now carried out solely by United Launch Alliance, a joint venture of Lockheed Martin Corp and Boeing Co. The Pentagon is eager to certify SpaceX as a second launch provider, given mounting concerns in Congress about ULA's use of a Russian-built engine to power its Atlas 5 rocket.

EU to resume Galileo satellite launch program

By Francesco Guarascio BRUSSELS (Reuters) - The European Union is set to send two navigation satellites into orbit on Friday aboard a Russian rocket, in its first launch since a botched deployment in August that cost several million euros to fix. The Galileo project to set up an EU alternative to the U.S. Global Positioning System (GPS) is obliged to use the Russian Soyuz system until a development of Arianespace's European Ariane 5 rocket is ready around the end of the year, despite strained relations with Moscow over the conflict in Ukraine. An official at the European Commission, which oversees the program, said the EU executive was tendering for insurance cover for future satellites and had set up an insurance scheme for the launches. The two launched in August have since been nudged into viable orbits and are fit for use, a spokesman for the European Space Agency said.

Ancient 4-Eyed Predator Wielded Wicked Toothy Claws

Ancient 4-Eyed Predator Wielded Wicked Toothy ClawsIt is the first new species reported from a stunning fossil find in Marble Canyon in British Columbia's Kootenay National Park. The Marble Canyon fossil beds, located in 2012, rival the iconic Burgess Shale for their diversity of soft-bodied fossils and exquisite preservation, scientists said. Yawunik is one of the most abundant species at the Marble Canyon site, and so, as a predator, likely held a key position in the food chain, said lead study author Cédric Aria, a graduate student in paleontology at the University of Toronto in Canada. The animal was named Yawunik kootenayi after the Ktunaxa people who have long inhabited the Kootenay area where the Marble Canyon locality was found.

DARPA seeks new positioning, navigation, timing solutions

The Defense Advanced Research Projects Agency (DARPA), writing about GPS, said: "The military relies heavily on the Global Positioning System (GPS) for positioning, navigation, and timing (PNT), but GPS access is easily blocked by methods such as jamming. In addition, many environments in which our military operates (inside buildings, in urban canyons, under dense foliage, underwater, and underground) have limited or no GPS access." This raises the questions of what DARPA plans as a step up. Will DARPA introduce relevant new technologies? Let DARPA say it in its own words: "GPS has provided a tremendous strategic advantage to the U.S. military, but heavy reliance on GPS has also become a strategic vulnerability. The need to be able to operate effectively in areas where GPS is inaccessible, unreliable or potentially denied by adversaries has created a demand for alternative precision timing and navigation capabilities."
