Visualization of fMRI Network Data

NASA’s Jet Propulsion Laboratory, Pasadena, California Functional connections within the brain can be revealed through functional magnetic resonance imaging (fMRI), which shows simultaneous activations of blood flow in the brain during response tests. However, fMRI specialists currently do not have a tool for visualizing the complex data that comes from fMRI scans. They work with correlation matrices that table what functional region connections exist, but they have no corresponding visualization.

Controlling Fast Acquisition Hardware to Pre-Position a Satellite to Constrain Baseband Searches

The primary use of this algorithm is in the acquisition of satellites under the conditions where almanac, ephemeris, and position data may not be available. Lyndon B. Johnson Space Center, Houston, Texas When adapting GPS sensor technology from an aviation environment to a space environment, the search window for a satellite’s frequency and code phase is greatly increased. This problem is also magnified when multiple antennas are used. A new algorithm is required to meet the demands of acquiring satellites in a space environment.

Rotary-Hammer Core Sample Acquisition Tool

This tool can be used for drilling in construction, mining, or scientific research applications. NASA’s Jet Propulsion Laboratory, Pasadena, California NASA is developing technologies to enable in situ analysis and sample acquisition from planetary bodies. Missions to these diverse locations require autonomous, highly customizable, reliable tools. A tool capable of core generation, capture, and transfer, and customizable for different missions, would be very valuable.

Mini Solar Observatory Can Be Used on Manned Spacecraft

Southwest Research Institute (SwRI) developed a miniature portable solar observatory for use onboard a commercial, manned, suborbital spacecraft. The SwRI Solar Instrument Pointing Platform (SSIPP) uses a classic, two-stage pointing system similar to larger spacecraft, but in this case, the first stage is a pilot who initially steers the instrument toward the Sun. SSIPP does the rest, locking onto the Sun to allow observations. The first SSIPP spaceflight will search for “solar ultrasound,” a phenomenon first observed in the early 2000s by the Transitional Region and Coronal Explorer (TRACE) spacecraft. The ultrasound is sound waves with a 10-second period, some 18 octaves deeper than ultrasound on Earth, and forms visible ripples in the Sun’s surface layers. The waves are difficult to detect without space instrumentation because the tiny, rapid fluctuations cannot be separated from the confounding influence of Earth’s turbulent atmosphere. Although at first SSIPP will be operated from inside the cockpit, a full system eventually will be mounted outside the host vehicle to enable UV and X-ray observations that are inaccessible from the ground.
