Twin U.S. satellites rocketed into orbit Thursday on a quest to explore Earth's treacherous radiation belts and protect the planet from solar outbursts. It's the first time two spacecraft are flying in tandem amid the punishing radiation belts, brimming with highly charged particles capable of wrecking satellites and endangering astronauts.
When the Space Shuttle Atlantis took off from Cape Canaveral on its final flight more than a year ago, a research team took advantage of this opportunity to track the 350-ton plume of water vapor exhaust that it released shortly after launch. Crossing through the paths of seven separate sets of instruments, the vapor spread far faster than expected and quickly moved to the Arctic. Such information will be used to inform global circulation models.
When man first harnessed fire, no one recorded it. When the Wright Brothers showed man could fly, only a handful of people witnessed it. But when Neil Armstrong took that first small step on the moon in July 1969, an entire globe watched from a quarter million miles away. Although more than half of the world's population wasn't alive then, it was an event that changed and expanded the globe.
Curiosity’s test drive was a success, allowing scientists at NASA to begin planning their next move. An intriguing spot 1,300 feet will mark the rover’s first attempt to drill into bedrock. The ultimate destination is Mount Sharp, a towering mountain that looms from the ancient crater floor. Signs of past water have been spotted at the base, providing a starting point to hunt for the chemical building blocks of life.
NASA has awarded the California Institute of Technology a new five-year contract to manage the agency's Jet Propulsion Laboratory (JPL). The contractor's primary mission is to support NASA's Science Mission Directorate (SMD) in carrying out specific objectives identified in the SMD Science Plan. The contract is for $8.5 billion.
Members of the Mars Science Laboratory Curiosity rover ChemCam team have received the first photos from the instrument's remote microimager. The successful capture of ChemCam's first 10 photos sets the stage for the first test bursts of the instrument's rock-zapping laser in the near future.
A penny-sized rocket thruster may soon power the smallest satellites in space. The device, designed at Massachusetts Institute of Technology, bears little resemblance to today's bulky satellite engines, which are laden with valves, pipes, and heavy propellant tanks. Instead, its design is a flat, compact square covered with 500 microscopic tips that, when stimulated with voltage, emit tiny beams of ions.
Living with a star can be a challenge, especially as Earthlings extend their reach into space. A Rice University scientist is contributing to an effort to make life more comfortable for both the people and satellites sent out there, and provide valuable research for those who remain planet-bound.
A faulty control fin prevented the X-51A Waverider from starting its exotic scramjet engine and it was lost Tuesday shortly after being launched. Though data showed the right conditions were achieved for engine ignition, the subsystem failure sent it plummeting into the Pacific Ocean. One Waverider remains.
Scientists at the Harvard-Smithsonian Center for Astrophysics and their colleagues at the Heidelberg Institute for Theoretical Studies have invented a new computational approach that can accurately follow the birth and evolution of thousands of galaxies over billions of years.
Last spring private industry successfully sent a spacecraft carrying cargo to the International Space Station. Now the race is on to see which company will be the first to make commercial human spaceflight a reality. Sierra Nevada Corporation will receive hundreds of millions of dollars to further develop its commercial human spacecraft system, NASA announced earlier this month; and they are now turning to Georgia Tech for help.
According to reports from the Los Angeles Times, a unmanned X-51 WaveRider is expected to reach Mach 6 Tuesday when it's dropped by a B-52 bomber and takes flight off the Southern California coast near Point Mugu. If it travels for 300 seconds it would double the previous flight time.
United Technologies Corp. announced it has completed its acquisition of Goodrich Corp., marking a major milestone for the company and strengthening its position in the commercial aerospace industry. Goodrich will be combined with Hamilton Sundstrand to create the new UTC Aerospace Systems business unit, headquartered in Charlotte, N.C.
Locale aside, Curiosity is giving scientists an unprecedented sense of what it took to reach its Martian destination. A low-quality video of the landing and the first color picture arrived quickly. Now, spectacular images of the crate in which the rover landed are beginning to arrive, and the best views—of Mars and the journey there—are yet to come.
After demonstrating more than 48 hours of continuous flight in a wind tunnel, Lockheed Martin and LaserMotive Inc. report they have completed a series of outdoor flight tests of the Stalker Unmanned Aerial System (UAS). These tests mark the first-ever outdoor flight of a UAS powered by laser.
NASA recently picked three aerospace companies to build small rocketships to take astronauts to the International Space Station. This is the third phase of NASA's efforts to get private space companies to take over the job of the now-retired space shuttle. The companies will share more than $1.1 billion. Two of the ships are capsules like in the Apollo era and the third is closer in design to the space shuttle.
NASA's Curiosity rover on Monday transmitted a low-resolution video showing the last 2 1/2 minutes of its white-knuckle dive through the Mars atmosphere, giving Earthlings a sneak peek of a spacecraft landing on another world. It was a sneak preview since it'll take some time before full-resolution frames are beamed back depending on other priorities.
According to a recent National Science Foundation report, the amount of R&D funding that passed through universities to others for collaborative projects during fiscal years 2000 to 2009 grew more rapidly than overall academic R&D expenditures. Federal initiatives and technological advances are thought to be contributing factors to this trend.
Cheers and applause echoed through the NASA Jet Propulsion Laboratory late Sunday after the most high-tech interplanetary rover ever built signaled it had survived a harrowing plunge through the thin Mars atmosphere. Minutes after the landing signal reached Earth at 10:32 p.m. PDT, Curiosity beamed back the first black-and-white pictures from inside the crater showing its wheel and its shadow, cast by the afternoon sun.
The size of a dishwasher, the Composite Infrared Spectrometer aboard NASA’s Cassini spacecraft made a number of important scientific discoveries. But now, scientists at the Goddard Space Flight Center are hoping to achieve the same sort of mid-infrared detection performance out of a wafer-like spectrometer that fits in the palm of a hand.
NASA's most ambitious and expensive Mars mission yet begins with the red planet arrival late Sunday of the smartest interplanetary rover ever built. But before Curiosity can start rolling it must survive a complicated touchdown so risky it's been described as "seven minutes of terror"—the time it takes to go from 13,000 mph to a complete stop.
R&D laboratories take on challenges of terrorism, energy, and communications in the new millennium.
Imagine being able to design a new aircraft engine part on a computer, and then being able to it. Not the design; the actual part. And not just a lightweight, nonfunctional model, but an actual working part to be installed in an engine. The University of Dayton Research Institute was awarded $3 million for the Ohio Third Frontier to provide specialized materials for use in additive manufacturing.
On Wednesday, Felix Baumgartner took another stratospheric leap, this time from an altitude of more than 18 miles—an estimated 96,640 feet, nearly three times higher than cruising jetliners. He landed safely near Roswell, N.M. His top speed was an estimated 536 mph, said Brian Utley, an official observer on site.
A large inflatable heat shield developed by NASA's Space Technology Program has successfully survived a trip through Earth's atmosphere while travelling at hypersonic speeds up to 7,600 mph. A cone of uninflated high-tech rings covered by a thermal blanket of layers of heat resistant materials, the shield was launched Monday from a three-stage Black Brant rocket for its suborbital flight.
