Laser demonstration reveals bright future for space communication

December 26, 2013 11:07 am | by Dewayne Washington, NASA's Goddard Space Flight Center | News | Comments

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.  

Europe launches satellite to map 1 billion stars

December 19, 2013 7:16 pm | by Danica Coto and Frank Jordans, Associated Press | News | Comments

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 orders urgent spacewalk repairs at station

December 17, 2013 6:30 pm | by MARCIA DUNN - AP Aerospace Writer - Associated Press | News | Comments

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.

NASA suspects bad valve for space station trouble

December 12, 2013 12:52 pm | by MARCIA DUNN - AP Aerospace Writer - Associated Press | News | Comments

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.

First rock dating experiment performed on Mars

December 11, 2013 8:23 am | News | Comments

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: Ancient Martian lake may have supported life

December 9, 2013 12:28 pm | by ALICIA CHANG - AP Science Writer - Associated Press | News | Comments

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.

Industry Breakout - Aerospace, Defense & Security

December 9, 2013 6:06 am | by R&D Magazine/Battelle | Articles | Comments

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.

Martian laser surpasses 100,000 zaps

December 5, 2013 3:26 pm | News | Comments

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.

Amazon.com sees delivery drones as the future

December 2, 2013 1:44 pm | by Scott Mayerowitz, AP Business Writer | News | Comments

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.

China launches first moon rover, the “Jade Rabbit”

December 2, 2013 9:19 am | News | Comments

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.

New energy conversion principle could double engine efficiency

November 27, 2013 11:17 am | News | Comments

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.

Energy savings in 3-D

November 21, 2013 7:37 am | News | Comments

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.

Mini space shuttle skids off runway in test flight

October 30, 2013 8:35 am | by Marcia Dunn, AP Aerospace Writer | News | Comments

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.

A new idea for space tourism: Balloon over rocket

October 23, 2013 2:25 pm | by Seth Borenstein, AP Science Writer | News | Comments

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.

Researchers evaluate electronic flight bags for Air National Guard pilots

October 16, 2013 8:06 am | News | Comments

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.

Water for future Mars astronauts?

September 27, 2013 7:55 am | News | Comments

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.

Terramechanics research aims to keep Mars rovers rolling

September 5, 2013 11:34 am | by Jennifer Chu, MIT News Office | News | Comments

In May 2009, the Mars rover Spirit cracked through a crusty layer of Martian topsoil, sinking into softer underlying sand. The unexpected sand trap permanently mired the vehicle. The mission mishap may have been prevented by a better understanding of terramechanics, which describes the interaction between vehicles and deformable terrain.
