Cyber-Training Today’s Fighting Forces

Dramatic changes are taking place in the way U.S. service men and women prepare for their assignments. Since 9/11, the U.S. Department of Defense (DoD) is moving from a training cycle in which pre-deployment training events for units and staffs were predictable and occurred every 18-24 months, to one in which deployments are occurring every 10-to-12 months. The Department’s leadership views virtual simulation, where soldiers can experience a wider variety of realistic training scenarios more frequently, as one way to supplement live training to prepare its forces to go into harm's way

Embedded Development and the .NET Micro Framework

The scenario: You’ve been assigned the task of designing and producing an embedded device. You’ve been given time, cost and size constraints that impact your design. An initial analysis of the requirements leads you to the conclusion that a 32-bit processor with a relatively small amount of RAM and Flash are required. A bit of research shows that an ARM processor with 2MB of external Flash and 2MB of external RAM will meet your cost and size constraints.

Taking Advantage of Parallel Parametric Testing

The production of many electronic devices begins with wafer processing. In addition to complementary metal oxide semiconductor (CMOS) integrated circuits (ICs), this can include such diverse devices as radio frequency (RF) components based on III-V compounds and chemical detectors based on carbon nanotube (CNT) field effect transistors (FETs). In both R&D and production applications, there is a great deal of effort devoted to increasing device test throughput in order to shorten the time to market and reduce costs.

Imaging Software Provides Access to Critical Mission Images Across NASA

Presto Imaging Software Inmagic Woburn, MA 781-287-6277 www.inmagic.com With every space shuttle mission, hundreds of individuals across NASA need to access extensive photographs, video footage, and other imaging assets in order to monitor launch results, review design decisions, and ensure mission safety. Additional video footage and still images shot on orbit enables NASA engineers to compare pre-flight and in-flight images in order to assess functionality and highlight areas that warrant further scrutiny. Until recently, only the Image Analysis Team (IAT) staff could view these baseline images, and sometimes with delays due to the complexity of accessing them.

Simulation Software Enables Development and Validation of NASA Probe Bus and Probe Carrier

MSC Nastran and MSC Adams Enterprise Simulation Software MSC.Software Corp. Santa Ana, CA 714-540-8900 www.mscsoftware.com NASA’s MIDEX Mission THEMIS (Time History of Events and Macroscale Interactions during Substorms) aims to resolve one of the oldest mysteries in space physics: namely, to determine what physical process in near-Earth space initiates the violent eruptions of the aurora that occur during substorms in the Earth’s magnetosphere. THEMIS is a 2-year mission consisting of five identical probes that will study the violent colorful eruptions of Auroras.

Jing Li, Scientist, NASA Ames Research Center, Moffett Field, CA

NASA recently tested the Nano ChemSensor, the first nanotechnology- based electronic device to fly in space. The test showed that the sensor could monitor trace gases inside a spaceship. This technology could lead to smaller, more capable environmental monitors and smoke detectors in future crew habitats. Jing Li, a NASA Ames scientist, is the principal investigator for the test.
