Enterprise Middleware Solution

Neil A. Armstrong Flight Research Center, Edwards, California An enterprise middleware solution allows disparate information technology (IT) systems to be integrated into one seamless, efficient system. As software and database platforms continue to develop at an accelerated pace, legacy systems can be a drain on resources, requiring complex workarounds and major code modifications in order to share data. This middleware offers an easy-to-use tool that integrates existing IT systems with new applications to help businesses become more agile, intelligent, and innovative.

Processing Time History Data for Display and Analysis

Neil A. Armstrong Flight Research Center, Edwards, California A suite of software tools was developed that enables powerful and efficient processing of time history data. These tools can be used together or independently, offering a variety of capabilities including comparison of time history data files to validate pre-processing activities, conversion from a compressed format to any format suitable for display, and plotting of data from multiple runs and input files using various time-function parameters. Originally developed to process flight test and simulation data, this suite has potential applications for the manufacturing, aerospace, and scientific research industries. These technologies offer a low-cost alternative to expensive, multiple-component data processing and plotting systems.

Prototype Genomics-Based Keyed-Hash Message Authentication Code Protocol

This is targeted for applications without an available public key infrastructure. Goddard Space Flight Center, Greenbelt, Maryland Cryptography and molecular biology share certain aspects and operations that allow for a set of unified principles to be applied to problems in either venue. A DNA-inspired hash code system is presented that utilizes concepts from molecular biology. It is a keyed-Hash Message Authentication Code (HMAC) capable of being used in secure mobile ad-hoc networks. It is targeted for applications without an available public key infrastructure. Ad-hoc does not mean the users are completely unknown to each other. They could be part of a military unit, police, emergency workers, mobile vendors, or any collection of users in a common geographical area that wish to communicate in a region lacking a PKI (Public Key Infrastructure).

Station Spacewalk

Ames Research Center, Moffett Field, California The Station Spacewalk game enables players to virtually conduct NASA repair work on the International Space Station, including jobs critical to help power up the space station so it can continue to operate. Players are provided with a limited quantity of oxygen during which they must complete extravehicular activities (EVAs) and return to the airlock before the air supply runs out.

Underwater Robot Offers New Look at Antarctic Sea Ice

The first detailed, high-resolution 3D maps of Antarctic sea ice have been developed using an underwater robot. Scientists from the UK, US, and Australia say the new technology provides accurate ice thickness measurements from areas that were previously too difficult to access.

Are we moving toward pilotless airliners?

This week's Question: NASA has worked with industry to help create the Synthetic Vision System (SVS), a virtual reality display system for cockpits. The SVS uses 3D to provide pilots with intuitive means of understanding their flying environment, including graphical displays of terrain and hazards. In coming months, Universal Avionics, an avionics manufacturer, will release a product called InSight, which blends larger displays, higher-resolution 3-D synthetic vision, and new icon-based command-and-control architecture. Some say that synthetic vision developments, along with other emerging aviation technologies like touch-screen steering and voice recognition, could lead to a day when airliners fly themselves. What do you think? Are we moving toward pilotless airliners?>
