Ultrasonic waves can find bubbles and cracks in adhesive bonds holding airplane composite parts together. Different ultrasonic modes work best for different materials and configurations using the right one will locate more flaws with higher precision. Recent research has produced a technique that lets aerospace engineers more quickly select the best frequencies to detect adhesive failures in hard-to-reach places.
Biotechnology company Zero Gravity Solutiuons aims to utilize the unique effects of extended zero/micro gravity environments available on the International Space Station to promote gene expression and accelerate stem cell research. The company has completed filings required prior to trading of the company’s stock.
In one of the most harrowing spacewalks in decades, an astronaut had to rush back into the International Space Station on Tuesday after a mysterious water leak inside his helmet robbed him of the ability to speak or hear at times and could have caused him to choke or even drown. Italian Luca Parmitano was reported to be fine after the dangerous episode, which might have been caused by an unprecedented leak in the cooling system of his suit.
Two Univ. of Michigan engineering professors are turning to the Kickstarter online community to help fund an interplanetary satellite mission. They are teaming up to create two new technologies in a matter of months, with the goal of using a plasma thruster to push a CubeSat into deep space—something that has never been done before.
Landing an airplane on an aircraft carrier deck is one of the most difficult tasks a pilot is asked to do. On Wednesday, the Navy will attempt to accomplish the same task with a drone. If all goes as planned, a successful landing of the X-47B experimental aircraft will mean the Navy can move forward with its plans provide around-the-clock surveillance and strike capability.
Explore an intriguing spot on Mars. Hunt for ancient signs of Martian life. Bag a bunch of rocks and leave them on the surface for a future mission to possibly return. That's what the next rover to Mars should strive for, a NASA-appointed team said Tuesday. The scientists released a 154-page report outlining ambitious science goals for a red planet mission that NASA wants to launch in 2020.
This revolutionary solar-powered plane is about to end a slow and symbolic journey across America by quietly buzzing the Statue of Liberty and landing in a city whose buildings often obscure the power-giving sun. But the Solar Impulse’s designers and flyers hope to grab attention in a surprising way: By being silent and consuming little energy.
Digital systems are an everyday routine for more and more passengers, and even Internet is now available. But pilots are largely cut off from this development with a system that is separate and largely analog. Under development in Germany is a new system that will digitally transmit air traffic and weather communications with the ground and via satellite at high speeds.
According to NASA, there are more than 21,000 pieces of “space junk roughly the size of a baseball in orbit, and about 500,000 pieces that are golf ball-sized. These pieces can be dangerous, which is why researchers at Texas Advanced Computing Center’s supercomputers are simulating orbital debris impacts on spacecraft and fragment impacts on body armor to help NASA design better shielding.
When the Concorde started flying in the 1970s, hopes were high that the traveling masses would soon streak through the air faster than the speed of sound or soar in planes that hurtled like missiles above the earth's atmosphere. Instead, jetliners still look the same as they did five decades ago and travel times have barely budged.
In recent years, formation control of multiple unmanned aerial vehicles has an important aerospace research topic. Engineers in China have recently investigated the trophallactic—or fluid exchange by direct contact—swarming behavior exhibited by a variety of animals, including birds and insects. By imitating that behavior and considering the communication requirements of the network control system, a new network control method was proposed.
When it's in flight, there's no roar of engines. It's strangely quiet. And as it crisscrosses the U.S., the spindly plane doesn't use a drop of fuel. Ernest Moniz, who heads the U.S. Department of Energy, praised the efficiency of the Solar Impulse plane at a news conference Monday in Washington, where the plane landed early Sunday morning. He said the solar-powered aircraft highlighted a cleaner energy future for the nation.
Boeing Corp. is starting work on a stretched-out version of its popular 787 Dreamliner jet, in the hope of reigniting interest in the aircraft after battery-related problems. Boeing announced the formal launch of its 787-10 program at the Paris Air Show on Tuesday and says it already has commitments from several customers, including United Airlines.
China's fifth and longest manned spacecraft successfully blasted off Tuesday on a 15-day mission to dock with a space lab and educate young people about science. The spacecraft was launched aboard a Long March 2F rocket and will transport the crew to the Tiangong 1, which functions as an experimental prototype for a much larger Chinese space station to be launched in 2020.
Neil Armstrong's name is attached to a lunar crater, an asteroid, more than a dozen schools and a museum, but not a single NASA facility is christened in honor of the man whose "giant leap" made him the first to walk on the moon. All that could soon change on the fringes of the Mojave Desert, where leaders at the space agency's top flight research center are mulling a name change.
A federal judge has approved a settlement in which United Technologies Corp. will sell some of its assets as part of its $18.4 billion purchase of aerospace-parts maker Goodrich Corp., the largest merger in aircraft industry history. The settlement between Hartford, Connecticut-based United Technologies and the Justice Department was approved Wednesday by U.S. District Court Judge Ketanji Brown Jackson.
An unmanned jet built for U.S. Navy high-altitude maritime surveillance missions has made its first flight. Northrop Grumman Corp. says the MQ-4C Triton took off from Palmdale, Calif., Wednesday and completed a 90-minute flight. The aircraft is designed to fly missions lasting up to 24 hours at altitudes greater than 10 miles, allowing coverage out 2,000 nautical miles.
A Colorado company developing a spaceship to take astronauts to the International Space Station is having elements of its spacecraft undergo landing-related tests at NASA facilities in Virginia and California. NASA wants private firms to ferry astronauts into low-Earth orbit so it can focus on deep-space exploration and send crews to a nearby asteroid and eventually Mars.
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.
Based on numbers from the latest contract between NASA and the Russian Space Agency, the United States is paying $424 million more to Russia to get U.S. astronauts into space. NASA Administrator Charles Bolden is is blaming Congress for the extra expense, saying reduced funding for commercial spaceflight development has forced the agency to sign the new contract.
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.
Orbital Sciences Corp. has won a $50 million contract to build a new satellite for NASA, the space technology company said Monday. The Dulles, Va.-based company will create and test a new heliophysics science satellite that is responsible for investigating the connection between space weather and Earth's terrestrial weather.
