Smoothing the Wave for High-Power Lasers

For years, laser manufacturers have promised the ability to produce very high-power, cost-effective lasers that are stable outside of a laboratory environment. Recent requirements in aerospace and defense applications, such as LIDAR (Light Detection and Ranging), IR countermeasures, and laser targeting, are now calling on these manufacturers to deliver.

Heat Exchanger Coils Control Temperature in NASA Icing Tunnel

Heat exchanger coilsSuper Radiator CoilsChaska,

A 25-foot-high wall of heat exchanger coils manufactured by Super Radiator Coils will replace the coils in the Icing Research Tunnel (IRT) at NASA’s John H. Glenn Research Center in Cleveland, OH. When installed and commissioned, the new coils will enable the IRT to lower the air temperature faster and more efficiently to -40 °F, which will be 15 degrees colder than its current capacity.

Laser Systems Will Enable NASA Satellite to Measure Sea Ice

Flight lasers and test laserFibertekHerndon,

Managed by NASA’s Goddard Space Flight Center in Greenbelt, MD, the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) mission is scheduled to launch in 2016. The satellite will replace the original ICESat observatory, which was decommissioned in 2010. Four flight lasers and one test laser for ICESat-2’s Advanced Topographic Laser Altimeter System instrument will be provided by Fibertek.

Modeling Design Software Gets the International Space Station Moving

Creo Direct v17 modeling design softwarePTC Corp.Needham,

There are several robotic arms on the International Space Station (ISS), but the two that NASA Johnson Space Center (JSC) robotics analysts deal with the most are the Space Station Remote Manipulator (SSRMS), known as the Canada Arm 2, and the Special Purpose Dexterous Manipulator (SPDM), appropriately named Dextre. Both are operated by the United States and Canada.

Network Connectivity Enables Climate Research

Summit® X650 40-GbEswitchExtreme NetworksSanta Clara,

Some of the largest data sets in existence are related to weather research, and that data is used throughout the world. The ability to rapidly share data across faster networks enables advances in global climate research. NASA’s Goddard Space Flight Center in Greenbelt, MD, is home to two of the world’s top climate modeling groups at the Greenbelt facility and at the Goddard Institute of Space Studies in New York. Goddard is working with Extreme Networks to evaluate high-speed, standards-based 40-GbE connectivity in support of global climate research.

Applying HDTV Imaging Technology To Industrial Applications

New high definition (HD) television cameras are being integrated into industrial environments to assist in the inspection of a variety of manufactured products. HDTV technology is reaching areas of application far outside the broadcast or entertainment markets, in part because of the capability of perfectly matching the cameras’ HD resolution, pixel to pixel, to high definition LCD and LED monitors, making these systems ideal for real-time, live viewing inspection.

NASA Analyzes Toyota Camry Software With Static-Analysis Tool

CodeSonar, Coverity Prevent, and Uno softwareGrammaTechIthaca,

The results of a ten-month study by 30 NASA engineers of possible electronic causes of unintended acceleration in Toyota vehicles was released recently by the U.S. Department of Transportation (DOT). At the request of Congress, the National Highway Traffic Safety Administration (NHTSA) began the study last March and asked NASA engineers with expertise in electronic and software systems to look into consumer claims that electronic systems may have played a role in reports of unintended acceleration.
