Titan Lake and Shore Sampler

The device is suitable for cryogenic dispensing of fluids, and for cryocoolers. NASA’s Jet Propulsion Laboratory, Pasadena, California A lake and shore sampling and sample distribution system was developed for a Titan lake environment (93.7 K, in liquid hydrocarbons). The Titan Lake and Shore Sampler (TLASS) would enable the chemical analysis of hydrocarbon lake samples via a Dual Rectilinear Ion and Orbitrap Mass Spectrometer and Nuclear Magnetic Resonance (NMR) Spectrometry.

VLBI Antenna Calibration by GPS

This technique could be adapted to monitor deformations of any large outdoor structure including dams, bridges, and buildings. Goddard Space Flight Center, Greenbelt, Maryland The determination of local geodetic parameters for VLBI (very-long-baseline interferometry) antennas is traditionally done by conventional surveying techniques. These techniques are laborious and error-prone. The objective here was to develop a space geodesy method of measuring the parameters to make it easy to reproduce and provide long-term monitoring of the parameters. Errors are reduced by automating the process.

Predicting Heart Age Using Electrocardiography

Lyndon B. Johnson Space Center, Houston, Texas Knowledge of a patient’s cardiac age, or “heart age,” could prove useful to both patients and physicians for encouraging lifestyle changes that are potentially beneficial for cardiovascular health. This may be particularly true for patients who exhibit symptoms, but who test negative for cardiac pathology.

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.
