Data from NASA's Cassini spacecraft have revealed Saturn's moon Titan likely harbors a layer of liquid water under its ice shell. Researchers saw a large amount of squeezing and stretching as the moon orbited Saturn. They deduced that if Titan were composed entirely of stiff rock, the gravitational attraction of Saturn would cause bulges, or solid "tides," on the moon only 3 ft in height. Spacecraft data show Saturn creates solid tides approximately 30 ft in height, which suggests Titan is not made entirely of solid rocky material.
NASA has selected a team including Southwest Research Institute to develop the Cyclone Global Navigation Satellite System (CYGNSS), which will provide better prediction capabilities for extreme weather events, particularly the intensification of hurricanes.
The European Space Agency's Euclid mission to explore the hidden side of the universe—dark energy and dark matter—reached an important milestone that will see it head towards full construction.
The European Space Agency (ESA) assembled a top engineering team then challenged them to devise a way for rovers to navigate on alien planets. Six months later, a fully autonomous vehicle was charting its own course through Chile's Mars-like Atacama Desert.
Researchers from the Georgia Tech Research Institute (GTRI) are helping convert an aircraft used to train pilots into one with intelligence, surveillance, reconnaissance (ISR) and light attack capabilities. The new aircraft would provide a less expensive alternative to legacy warbirds like the A-10 and F-16 and could be used by foreign military allies as well as U.S. homeland security agencies.
Complex systems inhabit a "gray world" of partial failures, Massachusetts Institute of Technology's Olivier de Weck says: While a system may continue to operate as a whole, bits and pieces inevitably degrade. Over time, these small failures can add up to a single catastrophic failure, incapacitating the system. However, De Weck and his colleagues have created a design approach that tailors planes to fly in the face of likely failures.
NASA’s next flagship mission, the James Webb Space Telescope, will carry the largest primary mirror ever deployed in space. Researchers has borrowed a page from its segmented mirror design to create a similar example just a half-inch in diameter. Strangely, the tiny mirror may one day become the standard for future space telescopes.
NASA has hired Space Exploration Technologies Corp. to deliver cargo to the International Space Station, but will eventually add astronauts. And the space agency is hiring other companies, too. Several firms—at least eight—think they can make money in space and are close enough to Musk's company to practically surf in his spaceship's rocket-fueled wake.
New research from North Carolina State University shows that a wind-driven "tumbleweed" Mars rover would be capable of moving across rocky Martian terrain—findings that could also help the National Aeronautics and Space Administration (NASA) design the best possible vehicle.
The SpaceX company made history as its Falcon 9 rocket, carrying 1,000 pounds of space station provisions in its Dragon capsule, rose from its seaside launch pad and pierced the pre-dawn sky, aiming for a rendezvous in a few days with the space station. If the mission proceeds as planned, Dragon will be the first commercial vessel to visit the space station.
A multiyear collaboration among Stanford University engineering departments uses some of the world's fastest supercomputers to model the complexities of hypersonic flight. Someday, their work may lead to planes that fly at many times the speed of sound.
After spending nearly five months conducting experiments in one spot, the NASA rover moved for the first time this week, rolling off the rock outcrop where it hunkered down for the Martian winter. Engineers will check its power supply before directing it north to study dust and bedrock.
Scientists on a planetary-heat-seeking mission have detected the first infrared light from a super-Earth—in this case, a planet some 40 light-years away. And according to their calculations, 55 Cancri e, a planet just over twice the size of Earth, is throwing off some serious heat.
A group of scientists took to the skies in a slow-moving airship Thursday in search of meteorites that rained over California's gold country last month. It's the latest hunt for extraterrestrial fragments from the April 22 explosion that was witnessed over a swath of Northern California and Nevada.
Part helicopter, part airplane, the Office of Naval Research-sponsored Flexrotor vertical takeoff and landing unmanned aerial vehicle has an oversized propeller with helicopter-like controls for vertical takeoff and landing and the wings of a conventional aircraft. If successful, the craft will extend UAV surveillance capabilities to smaller platforms like ships.
Radio signals reach pilots on board an aircraft through the radar dome, the rounded nose of the aircraft. But if imperfections are introduced during the production of this nose, it can impede radio traffic. Researchers have developed a non-destructive testing system that will identify these errors during production.
NASA is readying a fleet of four identical spacecraft, the Magnetospheric Multiscale (MMS) mission, for a 2014 launch to study space weather. The effort will require the development of highly sensitive spectrometers and cameras that operate at unprecedented performance levels.
As the Boeing 747 zoomed over the Manhattan skyline Friday, onlookers gawked at the unusual sight, realizing that the smaller plane hitched to its fuselage was an actual space shuttle. The Enterprise will soon make its home in New York City, basking in retirement about the Intrepid carrier in the Hudson River.
A group of high-tech tycoons wants to mine nearby asteroids wants to use commercially built robotic ships to squeeze rocket fuel and valuable minerals like platinum and gold out of the lifeless rocks that routinely whiz by Earth. The inaugural step, to be achieved in the next 18 to 24 months, would be launching the first in a series of private telescopes that would search for rich asteroid targets.
Launched from an air base in California last summer, DARPA’s unmanned glider Hypersonic Technology Vehicle-2, achieve stable, controlled flight at speeds of Mach 20 for about three minutes before its flight system forced the craft into the ocean. The agency says it now knows the probable cause of the premature end to the flight.
On December 24, 1968, the astronauts aboard Apollo 8 were conducting an extensive photographic survey of the moon’s surface. When they paused to take a navigation sighting, they were shocked to see the Earth “rising” above the lunar surface. Using modern imagery, NASA’s Lunar Reconnaissance Orbiter has recreated the moment, shortly before the first real photograph was taken.
Lockheed Martin extends 3D printing to manufacturing and custom vehicles.
Globalization, the personal computer, and changing priorities set the stage for R&D 100 Award Winners.
Evoking memories of the earliest shuttle flights that started with a mate-demate device atop a modified jumbo jet, the space shuttle Discovery this morning departed on its final flight from Florida’s Kennedy Space Center. The Discovery was bound for Washington, where it will become a museum piece at the Smithsonian Institution.
Starting Friday, NASA’s Mars Program Planning Group began accepting ideas and abstracts online from the worldwide scientific and technical community as part of NASA's effort to seek out the best and the brightest ideas from researchers and engineers in planetary science. They hope to develop a new strategy for the exploration of Mars.
