A Boeing 787 with a redesigned battery system made a 2-hour test flight on Monday, and the company said the event "went according to plan." The test flight was an important step in Boeing Co.'s plan to convince safety regulators to let airlines resume using the plane, which the company calls the Dreamliner.
Have you ever had a fighter jet fly over your home and the noise of the aircraft booms loud enough to rattle the windows? Imagine working on an aircraft carrier or air base, up close to the engines as they take off or land. Several U.S.-based research teams, with the support of the Office of Naval Research, have been tasked with finding a way to reduce that deafening noise as part of a three-year project.
Boeing's comments about the smoldering batteries on its 787 have annoyed the National Transportation Safety Board. Boeing gave its own account of two battery incidents, which included a fire, at a detailed press briefing in Tokyo last week. The problem is that the NTSB is still investigating the incidents. Boeing is a party to the investigation, meaning it provides technical experts and, in effect, gets a seat at the table as investigators try to sort out what happened.
Rusted pieces of two Apollo-era rocket engines that helped boost astronauts to the moon have been fished out of the murky depths of the Atlantic by Amazon.com CEO Jeff Bezos. A privately funded expedition led by Bezos raised the main engine parts during three weeks at sea, about 360 miles from Cape Canaveral. The engine parts were resting nearly 3 miles deep in the Atlantic
Innovnano, a manufacturer of high performance ceramic powder, has produced highly pure 4YSZ (4 mol% yttria stabilised zirconia), a thermal barrier coating material with exceptional properties for withstanding extreme temperature variations found in demanding operating environments. The patented manufacturing process delivers resilient coatings for improved turbine efficiency.
The space terminal for the Lunar Laser Communication Demonstration (LLCD), NASA's first high-data-rate laser communication system, was recently integrated onto the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft at NASA's Ames Research Center, Moffett Field, Calif. LLCD will demonstrate laser communications from lunar orbit to Earth at six times the rate of the best modern-day advanced radio communication systems.
The Mars rover Curiosity drilled into its first rock a month ago. Now scientists will reveal what's inside. Gathering at NASA headquarters Tuesday, the rover team will detail the minerals and chemicals found in a pinch of ground-up rock. The results come seven months after Curiosity made a dramatic landing in an ancient crater near the equator.
A private Earth-to-orbit delivery service made good on its latest shipment to the International Space Station on Sunday, overcoming mechanical difficulty and delivering a ton of supplies with high-flying finesse. The Dragon's arrival couldn't have been sweeter—and not because of the fresh fruit on board for the six-man station crew. Coming a full day late, the 250-mile-high linkup above Ukraine culminated a two-day chase that got off to a shaky, almost dead-ending start.
A commercial cargo ship rocketed toward the International Space Station on Friday under a billion-dollar contract with NASA that could lead to astronaut rides in just a few years. Launch controllers applauded and gave high-fives to one another once the spacecraft safely reached orbit. The rocket successfully separated from the white Dragon capsule, which contains more than a ton of food, tools, computer hardware, and science experiments.
Boeing CEO Ray Conner has met with Japan's transport minister and other officials in Tokyo to explain his company's proposal for resolving problems with the 787 Dreamliner's lithium-ion batteries that have kept the aircraft grounded for over a month.
Japanese investigators have identified the causes of fuel leaks and other problems with Boeing's 787 but are still investigating the more serious battery problem that forced an emergency landing in January and the worldwide grounding of the jets. The Transport Ministry on Friday released the results of its investigation into problems that occurred with 787 Dreamliner jets in January.
Fresh off drilling into a rock for the first time, the Mars rover Curiosity is prepping for the next step—dissecting the pulverized rock to determine what it's made of. NASA said Wednesday it received confirmation that Curiosity successfully collected a tablespoon of powder from the drilling two weeks ago and was poised to transfer a pinch to its onboard laboratories. It's the first time a spacecraft has bored into a rock on Mars to retrieve a sample from the interior.
A probe into the overheating of a lithium ion battery in an All Nippon Airways Boeing 787 found it was improperly wired, Japan's Transport Ministry said Wednesday. The Transport Safety Board said in a report that the battery of the aircraft's auxiliary power unit was incorrectly connected to the main battery that overheated, although a protective valve would have prevented power from the APU from doing damage.
Russia may suspend its lease for some facilities at the Baikonur space complex in Kazakhstan, opening the way for its joint administration by the two countries, a senior Russian space official says. The launch pad for satellite-deploying Zenit rockets at the complex will be the first facility to be reviewed, Roscosmos deputy head Sergei Savelyev told the Ivzestia newspaper in an interview published Thursday.
Electric rocket engines known as Hall thrusters, which use a super high-velocity stream of ions to propel a spacecraft in space, have been used successfully onboard many missions for half a century. Erosion of the discharge channels walls, however, has limited their application to the inner solar system. A research team at Caltech's Jet Propulsion Laboratory has found a way to effectively control this erosion by shaping the engine's magnetic field in a way that shields the walls from ion bombardment.
A U.N. agency that sets global aviation safety standards is moving to prevent aircraft batteries like the one that caught fire on a Boeing 787 last month from being shipped as cargo on passenger planes, people familiar with the effort said.
The U.S. government should reassess its safety approval of the Boeing 787's lithium ion batteries, America's top accident investigator said Thursday, casting doubt on whether the airliner's troubles can be remedied quickly.
The use of lithium ion batteries to power aircraft systems isn't necessarily unsafe despite a battery fire in one Boeing 787 Dreamliner and smoke in another, but manufacturers need to build in reliable safeguards, the nation's top aviation safety investigator said Wednesday.
Supersonic skydiver Felix Baumgartner was faster than he or anyone else thought during his record-setting jump last October from 24 miles up. The Austrian parachutist known as "Fearless Felix" reached 843.6 mph, according to official numbers released Monday. That's equivalent to Mach 1.25, or 1.25 times the speed of sound. His top speed initially was estimated at 10 mph slower at 834 mph, or Mach 1.24.
Japan's Transport Safety Board says the lithium ion battery aboard a Boeing 787 flight in Japan last month found evidence of the same type of "thermal runaway" seen in a similar incident in Boston. The board said in a report Tuesday that CAT scans and other analysis found damage to all eight cells in the battery that overheated on an All Nippon Airways 787 on Jan. 16, prompting an emergency landing.
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.
