Worldwide, hundreds of flights are diverted each year because of volcanic activity. Scientists monitoring Alaska's volcanoes have been forced to shut down stations that provide real-time tracking of eruptions and forgo repairs of seismic equipment amid ongoing federal budget cuts—moves that could mean delays in getting vital information to airline pilots and emergency planners.
Researchers at the U.S. Naval Research Laboratory (NRL) recently flew their fuel cell powered Ion Tiger UAV for 48 hours and 1 minute on April 16-18 by using liquid hydrogen fuel in a new, NRL-developed, cryogenic fuel storage tank and delivery system. This flight shatters their previous record of 26 hours and 2 minutes set in 2009 using the same vehicle, but with gaseous hydrogen stored at 5000 psi.
An experimental, unmanned aircraft developed for the U.S. Air Force went hypersonic during a test off the Southern California coast, traveling at more than 3,000 mph, the Air Force said Friday. The X-51A WaveRider flew for more than three minutes under power from its exotic scramjet engine and hit a speed of Mach 5.1, or more than five times the speed of sound.
On March 29, 2012, the science team for NASA's Fermi Gamma-ray Space Telescope learned that a defunct Cold-War spy satellite would pass too close for comfort on April 4. The two spacecraft were expected to occupy the same point in space within 30 milliseconds of each other. The story of how it sidestepped a potential disaster offers a glimpse at an underappreciated aspect of managing a space mission.
In a major step for Virgin Galactic’s bid to create the first space tourism company, the SpaceShipTwo made its first powered flight Monday, breaking the sound barrier in a test over the Mojave Desert. It then glided to a safe landing. The successful flight moves the company closer to its goal of flying paying passengers on brief hops into space.

Japan's transport minister says the government is poised to allow Japanese carriers to resume flying the Boeing 787 once they complete repairs to problematic lithium ion batteries. Transport Minister Akihiro Ohta says in a statement on the ministry's Website that the approval could come as early as Friday night following an expected official safety order from U.S. federal regulators.
Considered the world's most advanced sun-powered plane, the Solar Impulse took off from Moffett Field at NASA Ames Research Center in Mountain View on Friday at first light. The two-hour practice run was held in advance of a planned multi-city, cross-country tour, which previews a flight around in the world in about two years.
A company contracted by NASA to deliver supplies to the International Space Station successfully launched a rocket on Sunday in a test of its ability to send a cargo ship aloft. About 10 minutes after the launch from Wallops Island on Virginia's Eastern Shore, Orbital Sciences Corp. of Dulles declared the test a success after observing a practice payload reach orbit and safely separate from the rocket.
A test launch of an unmanned rocket that would eventually help carry supplies to the International Space Station has been rescheduled. NASA says the launch will take place no earlier than 5 p.m. Saturday, with a backup opportunity Sunday.
A private company contracted by the U.S. space agency to make supply runs to the International Space Station called off a test launch of an unmanned rocket, saying an important data cord linked to the rocket's second stage detached too soon. The Antares rocket had been scheduled to blast off Wednesday afternoon from Virginia when the countdown clock was halted 12 minutes before the expected launch.
The University of Connecticut and Pratt & Whitney this week celebrated the opening of a new Pratt & Whitney Additive Manufacturing Innovation Center at UConn, one of the most advanced additive manufacturing laboratories in the nation. Located on UConn’s Depot Campus in Storrs, the center features the latest in 3D manufacturing equipment and rapid prototyping technologies.
It's a good bet that in the not-so-distant future aerial drones will be part of Americans' everyday lives, performing countless useful functions. A far cry from the killing machines whose missiles incinerate terrorists, these generally small, unmanned aircraft will help farmers more precisely apply water and pesticides to crops, saving money and reducing environmental impacts. They'll help police departments find missing people, reconstruct traffic accidents and act as lookouts for SWAT teams.
Solar Impulse, considered the world's most advanced solar-powered plane, is set to travel across the United States, stopping for seven to 10 days at major airports in each city, so the pilots can display and discuss the aircraft with reporters, students, engineers and aviation fans. It plans to reach New York's Kennedy Airport in early July—without using a drop of fuel, its creators said.
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.
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.
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.
