Japanese and U.S. investigators are conducting a probe of the maker of the lithium ion batteries used in Boeing's grounded 787 jets. Tsutomu Nishijima, a spokesman for GS Yuasa, said Monday that the investigators visited the company's headquarters in Kyoto, Japan and that Yuasa was cooperating with the probe.
The battery that caught fire in a Japan Airlines 787 in Boston last week was not overcharged, but U.S. investigators said Sunday there could still be problems with wiring or other charging components. An examination of the flight data recorder indicated that the battery didn't exceed its designed voltage of 32 volts, the National Transportation Safety Board said in a statement.
Airbus said it was confident its planes would not encounter the same technical problems afflicting archrival Boeing's 787s, even though they use the same kind of batteries that have this week raised security concerns. The company may nevertheless be affected eventually, experts say. If investigations show that authorities had approved parts for the 787 that turned out to be deficient, Airbus may face tougher tests when it tries to launch a new plane this year.
NASA is partnering with a commercial space company in a bid to replace the cumbersome "metal cans" that now serve as astronauts' homes in space with inflatable bounce-house-like habitats that can be deployed on the cheap. A $17.8 million test project will send to the International Space Station an inflatable room that can be compressed into a 7-foot tube for delivery.
Boeing says production of its 787 is continuing as planned, even though airlines have grounded the plane because of safety concerns. Federal aviation officials grounded the plane until they can figure out a solution to electrical problems that have caused one battery to catch fire and another to leak in the past two weeks. It's not clear how long the grounding will last.

A $17.8 million test project will send to the International Space Station an inflatable room that can be compressed into a 7-foot tube for delivery, officials said Wednesday in a news conference at North Las Vegas-based Bigelow Aerospace.
Boeing's 787 is supposed to revolutionize air travel. It just needs to get out of its own way first. The new plane is undoubtedly Boeing's most visible. It's built from composites instead of aluminum and comes with the promise of the most comfortable ride in the sky. At $200 million each, 787s are an important part of Boeing's future, even though it will be a while before it makes money on them.
The military's small, top-secret version of the space shuttle rocketed into orbit Tuesday for a repeat mystery mission, two years after making the first flight of its kind. The X-37B is about one-quarter the size of the original NASA space shuttle and can land automatically. The purpose of this mission remains a secret: Launch commentary ended 17 minutes into the flight.
Eugene A. Cernan, a Purdue University alumnus and the most recent person to walk on the moon, stepped out of the lunar lander 40 years ago Tuesday. Commander of Apollo 17, Cernan made three moonwalks, explored the barren landscape in a lunar rover, collected about 250 pounds of soil samples and moon rocks, and took scientific measurements.
A new venture called Golden Spike Co. was announced on Thursday that hopes to offer trips for two to the moon for a cool $1.5 billion. Some space experts are skeptical of the firm’s financial ability to get to the moon, but the team of former NASA executives believe they can combine the technical might of Apollo with the marketing of Apple.
Results presented Wednesday at the meeting of the American Geophysical Union meeting in San Francisco show that the moon took a beating in its early days, far more than previously believed. Detailed gravity mapping by NASA’s Ebb and Flow spacecraft show the extent to which the moon was broken up and shattered from bombardment by asteroids and comets.
The space agency on Tuesday announced plans to launch another mega-rover to the red planet in 2020 that will be modeled after the wildly popular Curiosity. To keep costs down, engineers will borrow Curiosity's blueprints, recycle spare parts where possible and use proven technology including the novel landing gear that delivered the car-size rover inside an ancient crater in August.
Results are in from the first test of Martian soil by the rover Curiosity: So far, there is no definitive evidence that the red planet has the chemical ingredients to support life. Scientists said Monday a scoop of sandy soil analyzed by the rover's chemistry lab contained water and a mix of chemicals, but not the complex carbon-based compounds considered necessary for microbial life.
A team of researchers have built a new type of nuclear reactor that is reliable enough to be used on space flights. The prototype, which has been used to generate 24 W of electricity, relies on heat pipe technology developed at Los Alamos National Laboratory in 1983. The fluid-based cooling system requires no moving parts and the reactor itself is based on a simply closed-loop Stirling engine.
Engineers at Carnegie Mellon University and Concurrent Technologies Corporation are working with the Air Force Research Laboratory and Ogden Air Logistics Center 309 AMXG to develop and demonstrate a robotic system that uses high-powered lasers to remove coatings from fighter and cargo aircraft. The continuous-wave lasers should replace abrasives and chemicals used in traditional coating removal processes.
At NASA's Marshall Space Flight Center, a manufacturing technique called selective laser melting, or SLM, to create intricate metal parts for America's next heavy-lift rocket. Working from a 3D computer-aided design computer file, the machine basically “prints” complex parts using metal powder and lasers. The process significantly reduces the manufacturing time required to produce parts from months to weeks or even days, in some cases.
A California judge has tentatively ruled in favor of NASA's Jet Propulsion Laboratory in a wrongful termination lawsuit brought by a former computer specialist who alleged he was singled out in part because of his belief in intelligent design.
A set of instruments aboard the rover has ingested and analyzed samples of the atmosphere collected near the "Rocknest" site in Gale Crater where the Curiosity rover is stopped for research. With these initial sniffs of Martian atmosphere, preliminary results reveal little to no methane. Methane is of interest as a simple precursor chemical for life.
Two months ago, a problem with a control fin caused an X-51A to lose balance and crash off the Southern California coast. Research on the cause pointed to a mysterious “random vibration issue”. The U.S. military says it is planning a fourth attempt at unmanned hypersonic flight next spring or summer.
An astronaut departing this week for the International Space Station said Monday that the bulk of the scientific benefits from the orbiting laboratory will be seen over the coming decade, amid questions on whether the estimated $100 billion spent in last 12 years is worth the effort. Portland, Indiana-born Kevin Ford said the station is just now entering the phase where the bulk of science being conducted there will come to fruition.
Predicted by Albert Einstein's general theory of relativity, the waves occur when massive celestial objects move and disrupt the fabric of space-time. But by the time these waves reach Earth, they are so weak that the planet expands and contracts less than an atom in response. No instrument or observatory has ever directly detected them. A pioneering technology capable of atomic-level precision is now being developed to detect what so far has remained imperceptible.
The ability to ingest solid samples and examine them using X-ray diffraction is a core capability for the Curiosity rover. This week that ability was tested using a small scoop of minerals that has been shaken to remove any residues carried from Earth. These particles have been placed inside CheMin, an analytical instrument about the size of a laptop computer inside a carrying case.
According to a NASA engineer, “Fearless Felix” Baumgartner's death-defying jump Sunday from a balloon 24 miles above Earth gives us a good foundation for improving the odds of survival for professional astronauts, space tourists, and high-altitude pilots and passengers. Researchers have spent decades working on self-contained space escape systems, with no significant advances since Joe Kittinger in 1960 jumped from 19.5 miles up and reached 614 mph.
NASA's Commercial Crew Program (CCP) partner Blue Origin has successfully fired the thrust chamber assembly for its new 100,000 pound thrust BE-3 liquid oxygen, liquid hydrogen rocket engine. As part of Blue's Reusable Booster System (RBS), the engines are designed eventually to launch the biconic-shaped space vehicle the company is developing.
Scientists have pieced together the sequence of events of the farthest touchdown a man-made spacecraft has ever made on an alien world. Their work in tracking the bounces, wobbles, and skids the probe made before coming to rest on Titan reveals new clues about the Saturn moon’s surface and helps plan future missions to moons and planets.
