At the time the government certified Boeing's 787 Dreamliners as safe, federal rules barred the type of batteries used to power the airliner's electrical systems from being carried as cargo on passenger planes because of the fire risk. Now the situation is reversed.
Sea Launch AG says a U.S. communications satellite was lost after a booster rocket carrying it into space failed shortly after its launch from a floating platform in the Pacific. The company said in a statement Friday the Intelsat 27 satellite was lost 40 seconds after the launch due to the failure of the Zenit-3SL rocket.
Japan's Civil Aviation Bureau is sending investigators looking into problems with Boeing 787 batteries to Seattle, where the aircraft are assembled. The Transport Ministry said members of the team working on the investigation would leave Tokyo on Sunday for Seattle. It provided no further details.
Boeing is sticking with plans to speed up production of its 787 and sees no reason to change the lithium-ion battery design at the center of the troubled plane's problems, its CEO said Wednesday. Boeing's full-speed-ahead approach comes even as it became clear that airlines were replacing 787 batteries more often than Boeing had expected.
A new massive blimp-like aircraft was recently hovering just a dozen feet off a military hangar floor during flight testing south of Los Angeles. The fact that the hulking Aeroscraft could fly for just a few minutes represents a step forward in aviation, according to the engineers who developed it. According to the Department of Defense and NASA, their prototype could one day carry more cargo than any other aircraft to disaster zones and forward military bases.
Young engineers who weren't even born when the last Saturn V rocket took off for the moon are testing a vintage engine from the Apollo program. The engine, known to NASA engineers as No. F-6049, was grounded because of a glitch during a test in Mississippi and later sent to the Smithsonian Institution. Now, NASA engineers are using to get ideas on how to develop the next generation of rockets for future missions to the moon and beyond.
The joint U.S. and Japanese investigation into the Boeing 787's battery problems has shifted from the battery-maker to the manufacturer of a monitoring system. Japan transport ministry official Shigeru Takano said Monday the probe into battery-maker GS Yuasa was over for now as no evidence was found it was the source of the problems.
Obama administration officials struggled Wednesday to defend their initial statements that the Boeing 787 is safe while promising a transparent probe of mishaps involving the aircraft's batteries. Transportation Secretary Ray LaHood stood by his Jan. 11 assertion that the 787, Boeing's newest and most technologically advanced airliner, was safe.
When satellites retire, certain parts—such as antennas and solar panels—often still work. There's currently no routine effort to salvage and reuse satellite parts once they're launched into space. The Defense Advanced Research Projects Agency is spending $180 million to test technologies that could scavenge defunct communication satellites for their valuable parts and recycle them to build brand new ones for cheap.
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.
