An unmanned rocket blasted into a chilly, clear sky Thursday night carrying the latest, third-generation Tracking and Data Relay Satellite (TDRS). The TDRS system, used on several satellites to support the International Space Station and Hubble Space Telescope, is so vital it's considered a national asset. Together they supply real-time global coverage at all times.
A decade after landing on Mars, the rover Opportunity is still chugging along. Sure, it has some wear and tear. One of its six wheels and two instruments stopped working long ago. It has an arthritic joint. Its flash memory occasionally suffers a senior moment. But these problems are considered minor for a journey that was supposed to be just a three-month adventure.
On Thursday, Jan. 23, Sierra Nevada Corp. will publicly discuss expansion plans for its Dream Chaser Space System Program. The press conference, to be held at NASA’s Kennedy Space Center in Florida, will detail the company’s efforts to build a winged, lifting-body spacecraft that provides a flexible, credible, affordable solution for ISS crew transportation.
Aircraft maker Boeing Co., Etihad Airways, the oil company Total and others say they will work together on a program to develop an aviation biofuel industry in the United Arab Emirates. Etihad ran a 45-minute demonstration flight Saturday in a Boeing 777 partially powered by aviation biofuel produced in the UAE.
According to Anupam Agrawal, a professor of business administration at the Univ. of Illinois, Urbana-Champaign, firms can manage their sourcing better by developing relationships not only with their suppliers but also with their suppliers’ suppliers. The lack of communication or collaboration between the big players at either end of the supply chain spectrum can prevent gains in efficiencies.
The completion of the 30-day Lunar Laser Communication Demonstration (LLCD) mission has helped confirm laser communication capabilities from a distance of almost 250,000 miles. In addition to demonstrating record-breaking data download and upload speeds to the moon at 622 and 20 Mbps, respectively, LLCD also showed that it could operate as well as any NASA radio system.
Astronomers are still largely working with a “flat” map of the galaxy, and the European Space Agency hopes to change that with Gaia, its star-surveying satellite which launched into space Thursday. The spacecraft will produce the most accurate 3-D map of the Milky Way yet. Gaia is now heading for a stable orbit on the opposite side of the Earth from the sun, and will always keep its back to the sun.
NASA has ordered up a series of urgent spacewalks to fix a broken cooling line at the International Space Station, a massive repair job that could stretch to Christmas Day. Station managers decided Tuesday to send two American astronauts out as soon as possible to replace a pump with a bad valve. The task will require two and possibly three spacewalks on Saturday, Monday and next Wednesday.
The astronauts aboard the International Space Station dimmed the lights, turned off unnecessary equipment and put off science work Thursday as NASA scrambled to figure out what's wrong with a key cooling unit. One of two identical cooling loops shut down Wednesday when the line got too cold because of a faulty valve. The system uses ammonia to dissipate heat from onboard equipment.
Although researchers have determined the ages of rocks from other planetary bodies, the actual experiments have been done on Earth. Now, for the first time, researchers have successfully determined the age of a Martian rock with experiments performed on Mars. The work could not only help in understanding the geologic history of Mars but also aid in the search for evidence of ancient life on the planet.
NASA's Curiosity rover has uncovered signs of an ancient freshwater lake on Mars that may have teemed with tiny organisms for tens of millions of years, far longer than scientists had imagined, new research suggests. The watering hole near the Martian equator existed about 3.5 billion years ago. Scientists say it was neither salty nor acidic, and contained nutrients—a perfect spot to support microbes.
R&D among aerospace, defense and security firms is primarily driven by two sectors: the U.S. Department of Defense (DOD) and the global airline industry. The major aerospace and defense contractors plan R&D in close coordination with DOD to meet the needs of national defense and global security, while capacity, economics and efficiency are drivers for civil aviation requirements.
The ChemCam laser instrument aboard NASA’s Curiosity rover fired its 100,000th shot recently, chronicling its adventures on Mars with a coffee-table-book’s worth of spectral data that might rival snapshots gathered during a long and satisfying family vacation here on Earth. ChemCam zaps rocks with a high-powered laser to determine their composition and carries a camera that can survey the Martian landscape.
Online retailer Amazon.com aiming to deliver packages quicker than pizza. Its so-called Prime Air unmanned aircraft project, now underway in Amazon’s research and development labs, could get goods to customers in 30 minutes or less. But the company admits it will take years to advance the needed technology and for the needed federal Aviation Administration rules and regulations to be created.
On Monday, China launched its first rover mission to the moon, sending a robotic craft named Jade Rabbit to trundle across the lunar landscape, examine its geology and beam images back to Earth. If the Chang'e 3 successfully soft-lands on the moon, China will become the third country to do so, after the United States and the former Soviet Union.
Professor Ken Naitoh of Waseda Univ.'s Faculty of Science and Engineering has discovered a new compressive combustion principle that could yield engines with a much higher level of thermal efficiency: up to 60% or more in applications including automobiles, power generation and aircraft.
Researchers at Oak Ridge National Laboratory are working with aircraft makers to determine energy savings through the use of additive manufacturing, also known as 3-D printing. The research team is printing airplane parts to show additive manufacturing’s potential as a technology that should be considered foundational to processes seeking more energy efficiency.
A new, smaller version of NASA's space shuttle, the Dream Chaser space plane, is recuperating from a rough first landing. A helicopter dropped the unmanned craft from 12,500 feet in a first free flight reminiscent of NASA's drop tests of the shuttle prototype Enterprise in the 1970s. Everything worked well for the automated plane until the end, when the left landing gear deployed too late and the test vehicle skidded off the runway.
The latest space tourism venture depends more on hot air than rocket science. World View Enterprises announced plans Tuesday to send people up in a capsule, lifted 19 miles by a high-altitude balloon. While it's not quite space, the plan requires approval from the Federal Aviation Administration, which oversees commercial space.
When pilots encounter an in-flight emergency they consult with manuals, emergency procedures and other reference materials contained in their flight bags for information on how to respond. In the future, these cumbersome flight bags could be replaced by “electronic flight bags” consisting of a lightweight tablet computer loaded with electronic versions of documents that today are printed on paper.
NASA's Jupiter-bound spacecraft hit a snag last week after it flew past Earth to increase its speed to barrel beyond the asteroid belt to Jupiter. The Southwest Research Institute, which leads the mission's science operations, now reports that Juno is out of "safe mode."
A SpaceX rocket launched from the California coast Sunday carrying a Canadian satellite intended to track space weather in what was billed as a test flight. The Falcon 9 rocket lifted off from Vandenberg Air Force Base, about 150 miles northwest of Los Angeles, shortly after 9 a.m. under clear skies.
Within its first three months on Mars, NASA’s Curiosity Rover saw a surprising diversity of soils and sediments along a half-kilometer route that tell a complex story about the gradual desiccation of the Red Planet. Perhaps most notable among findings from the ChemCam team is that all of the dust and fine soil contains small amounts of water.
Chinese scientists described the country's first moon rover on Wednesday and invited the global public to come up with a name for it. The rover has two wings, stands on six wheels, weighs 140 kg and will be powered by solar energy. It will soft-land on the moon after a launch aboard the spacecraft Chang'e-3 in December.
A brand new commercial cargo ship making its orbital debut experienced trouble with a computer data link Sunday, and its arrival at the International Space Station was delayed at least two days. The rendezvous was aborted less than six hours before the scheduled arrival of Orbital Sciences Corp.'s Cygnus capsule, packed with 1,300 lbs of food and clothes for the space station crew.
