Software for Executing International Standard CCSDS 123B

Advanced remote-sensing instruments in recent years often employ multiple wavelengths for maximal science return. Many of them comprise hundreds to over a thousand spectral bands. These instruments multiply the data volume and stress the communication bandwidth. With previously deployed space lossless data compression standards only applicable to individual bands, a need exists to further improve performance by using spectral information.

TASAR and TAP: Airborne Trajectory Management Enabled by Traffic-Aware Software

This innovation consists of the Traffic Aware Strategic Aircrew Request (TASAR) concept and the associated Traffic Aware Planner (TAP) software. TASAR is intended to enable pilots to discover trajectory improvement opportunities while en route that will result in immediate operational benefits for the airspace user and be approvable by Air Traffic Control (ATC). TAP is a cockpit-based advisory tool that enables the TASAR concept, and it was developed to be hosted on a Class 2 Electronic Flight Bag. This near-term concept provides pilots with a strategic re-planning capability that optimizes fuel burn or flight time; avoids interactions with known traffic, weather, and restricted airspace; and may be used by the pilots to request a trajectory change from ATC with increased likelihood of approval. TAP’s internal architecture and algorithms are derived from the Autonomous Operations Planner (AOP), a flight-deck automation system developed by NASA to support research into aircraft self-separation.

Module::Build::Database

Module::Build::Database was developed as part of the Atmospheric Composition Processing System, which works with the Science Investigator-Led Processing System for the Ozone Monitoring Instrument. The technology allows the user to distribute changes to the schema in a database alongside software that relies on the database.

Big Ideas for Small Spaces

Over 24 hours from April 4 to 5, six top French design studios conceived and presented new product concepts for urban environments during the Small Spaces Design Hackathon, presented by Cut&Paste in partnership with Hewlett-Packard. In dense city neighborhoods, homes are small and office space is at a premium, so urban dwellers must be more creative in how they use their space. The design concepts were presented at Cyclone Le Studio as part of ZED, HP’s creative popup space.

Remote Sensing Moisture Model Could Aid Farmers

Global farmers could get better decision-making help as refinements are made to North Alabama soil moisture modeling research being done by an atmospheric science doctoral student at The University of Alabama in Huntsville. The models indicate how much added moisture would be needed in a given area versus historical data to achieve various crop yields, and they could aid in making expensive infrastructure investments by helping to determine their economic viability.

NASA Model Provides 3-D View of L.A. Earthquake

On March 28, residents of Greater Los Angeles experienced the largest earthquake to strike the region since 2008. The magnitude 5.1 quake was centered near La Habra in northwestern Orange County about 21 miles (33 kilometers) east-southeast of Los Angeles, and was widely felt throughout Southern California. There have been hundreds of aftershocks, including one of magnitude 4.1.Scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif., have developed a model of the earthquake, based on the distribution of aftershocks and other seismic information from the U.S. Geological Survey.A new image based on the model shows what the earthquake may look like through the eyes of an interferometric synthetic aperture radar, such as NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR). JPL scientists plan to acquire UAVSAR data from the region of the March 28 quake, possibly as soon as this week, and process the data to validate and improve the results of their model. The UAVSAR flights serve as a baseline for pre-earthquake activity. As earthquakes occur during the course of this project, the team is measuring the deformation at the time of the earthquakes to determine the distribution of slip on the faults, and then monitoring longer-term motions after the earthquakes to learn more about fault zone properties.

Engineers Design Software Tools to Secure Tactical Smartphones

Suraj Kothari's talk of smartphone security quickly took a turn toward sabotage and worst-case scenarios. What happens, he asked, if a soldier's smartphone is hacked for its GPS data? What happens if an attacker drains the battery in a general's phone and essential communication is cut off? Or, what happens if a hacked phone provides false information during a military mission?
