Machine Vision for High-Precision Volume Measurement in Levitated Materials Processing

Marshall Space Flight Center, Alabama A new program has been written that utilizes advanced numerical methods to perform high-precision, sub-pixel volume measurements of samples that are processed containerlessly. The volume measurements are essential for the measurement of density and thermal expansion.

Lunar Mapper v1

Marshall Space Flight Center, Alabama Lunar Mapper (LM) is a Web-based software that allows visualization of lunar spatial data layers acquired from lunar missions and other sources. The data includes imagery, digital elevation models, resource maps, and model output. LM is accessed using standard Web browsers and uses open-source tools and libraries. The data is stored on remote servers and viewed by the LM Web client. LM allows creation of project files to save user-specific data for future retrieval and collaboration.

Integrated and Automated Software Test Environment for JPL Software Defined Radio

NASA’s Jet Propulsion Laboratory, Pasadena, California Software has been developed that provides an integrated and automated test environment for the Space Telecommunications Radio System (STRS). This software package is Linux based and provides interactive and scripted control to test the JPL Software Defined Radio (SDR) implementing STRS hardware and software functionality. It also provides error checking and data logging capabilities for system diagnosis. This is a C programming language-based software that uses the host’s serial interfaces, a Ballard Technology, Inc. 1553 bus interface, and Star-Dundee SpaceWire-USB interface to communicate with the JPL SDR to issue test commands, receive telemetry, and transfer files.

Integrated Data Acquisition and Measurement Hardware Tests New Launch System

NI PXI DMM and NI PXI multifunction DAQ module National Instruments Austin, TX 1-800-531-5066 www.ni.com Larger than the Saturn V rocket and designed to eventually take crewed missions to Mars, the Space Launch System (SLS) will be the most powerful, versatile rocket ever created. Before its maiden launch in 2017, the rocket will go through testing at various facilities throughout the US, with one of the most impressive being the large structural tests scheduled for 2015 at NASA’s Marshall Space Flight Center in Alabama.

University Opens New Ballistics and Impact Dynamics Lab

Wichita State University’s National Institute for Aviation Research recently opened a new ballistics and impact dynamics research lab in the former Britt Brown Arena at the Kansas Coliseum. The new ballistics lab, part of NIAR’s environmental Test Labs, uses a custom built ballistic firing device to propel 22-50 caliber rounds into components inside a concrete containment building. The test is designed to simulate the impact of a structural failure on the aircraft.

Army to Get New IED Detector Technology

Detecting improvised explosive devices in Afghanistan requires constant, intensive monitoring using rugged equipment. When Sandia researchers first demonstrated a modified miniature synthetic aperture radar (MiniSAR) system to do just that, some experts didn't believe it. But those early doubts are long gone. Sandia's Copperhead — a highly modified MiniSAR system mounted on unmanned aerial vehicles (UAVs) — has been uncovering IEDs in Afghanistan and Iraq since 2009. Now, according to senior manager Jim Hudgens, Sandia is transferring the technology to the U.S. Army to support combat military personnel.
