Predicted by Albert Einstein's general theory of relativity, the waves occur when massive celestial objects move and disrupt the fabric of space-time. But by the time these waves reach Earth, they are so weak that the planet expands and contracts less than an atom in response. No instrument or observatory has ever directly detected them. A pioneering technology capable of atomic-level precision is now being developed to detect what so far has remained imperceptible.
The ability to ingest solid samples and examine them using X-ray diffraction is a core capability for the Curiosity rover. This week that ability was tested using a small scoop of minerals that has been shaken to remove any residues carried from Earth. These particles have been placed inside CheMin, an analytical instrument about the size of a laptop computer inside a carrying case.
NASA's Commercial Crew Program (CCP) partner Blue Origin has successfully fired the thrust chamber assembly for its new 100,000 pound thrust BE-3 liquid oxygen, liquid hydrogen rocket engine. As part of Blue's Reusable Booster System (RBS), the engines are designed eventually to launch the biconic-shaped space vehicle the company is developing.
Scientists have pieced together the sequence of events of the farthest touchdown a man-made spacecraft has ever made on an alien world. Their work in tracking the bounces, wobbles, and skids the probe made before coming to rest on Titan reveals new clues about the Saturn moon’s surface and helps plan future missions to moons and planets.
The United States may lose its leadership role in space to other countries unless it makes research and development funding and processes—especially in nanotechnology—a renewed and urgent priority, according to a new paper from Rice University's Baker Institute for Public Policy.
Felix Baumgartner stood poised in the open hatch of a capsule suspended above Earth, wondering if he would make it back alive. Twenty four miles below him, millions of people were right there with him, watching on the Internet and marveling at the wonder of the moment. Nine minutes later he landed, becoming the world's first supersonic skydiver.
New Mexico Tourism Secretary Monique Jacobson says it will be New Mexico's Sydney Opera House. Virgin Galactic Chairman Richard Branson has hinted it will host the first of his new brand of lifestyle hotels. But the nearly quarter-of-a-billion-dollar Spaceport America in New Mexico project has yet to attract the sort of industrial and investment activity expected, even as it nears phase one completion.
For airline passengers who dread bumpy rides to mountainous destinations, help may be on the way. A new turbulence avoidance system, developed by the National Center for Atmospheric Research, has for the first time been approved for use at a U.S. airport and can be adapted for additional airports in rugged settings across the United States and overseas.
An important test is coming up next week to see whether a heat shield made from the soil of the moon, Mars, or an asteroid will stand up to the searing demands of a plunge through the Earth's atmosphere. At stake is the possibility that future spacecraft could leave Earth without carrying a heavy heat shield and instead make one on the surface of another world and ride it home safely.
When the Dark Energy Camera opened its giant eye last week and began taking pictures of the ancient light from far-off galaxies, more than 120 members of the Dark Energy Survey eagerly awaited the first snapshots. Those images have now arrived.
The NASA Goddard Space Flight Center has awarded a SBIR Phase II program to Tahoe RF Semiconductor Inc. for developing a miniaturized Radiation Hardened Beam-Steerable GPS Receiver Front End for NASA spacecrafts.
This week, design company 4DSP has launched live industry demonstrations of licensed NASA fiber optic sensing and 3D shape rendering technology. Past fiber optic sensing solutions have been limited by both processing speed and high deployment costs, and 4DSP expects the new technology to offer a 20-fold improvement in performance.
According to data from a 2008 Business R&D and Innovation Survey by the National Science Foundation, businesses perform the lion's share of their R&D activity in just a small number of geographic areas, particularly the San Jose-San Francisco-Oakland area and the New York-Newark-Bridgeport area.
Scientists using the Mini-RF radar on NASA's Lunar Reconnaissance Orbiter have successfully estimated the maximum amount of ice likely to be found inside a permanently shadowed lunar crater located near the moon's South Pole. Their results, which offer more definite support to prior findings, show as much as 5 to 10% of the material, by weight, could be patchy ice.
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.
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.
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.
