Coming Soon - Is Your Data Acquisition System Prepared for Big Data?

Data acquisition systems are producing more analog data than ever before. This opportunity to uncover new insights comes at the risk of spending more time searching for and analyzing multiple data sets. Without proper data management, it is easy for important results to go unnoticed, causing repeated tests due to lost or undocumented data. Learn how proper metadata documentation, custom triggering, and implementing the right analysis technique help to save only the data you need to make informed decisions.

Coming Soon - Cybersecurity Challenges and Solutions

Today’s world is more interconnected than ever before. Yet, for all its advantages, increased connectivity brings increased risk. Cyberspace and its underlying infrastructure are vulnerable to those seeking to disrupt or destroy everything from medical records and robots, to industrial machinery and automobiles. More pressure will be placed on designers of these products to ensure that all available technologies are implemented to protect against attacks.

Logistics for Building Radiation Storm Shelters and their Operational Evaluation

Various habitat structures were tested for use in exploration activities.Over the past three years, NASA has been studying the operational effectiveness and astronaut protection efficacy of numerous radiation protection shelters for use in space exploration activities outside of Earth's magnetosphere. The work was part of NASA's Advanced Exploration Systems (AES) RadWorks Storm Shelter project. Fabricated items were integrated into mockup deep space habitat vehicle sections for operational evaluations. Two full-scale human-in-loop simulations were designed, fabricated, and implemented. The goal was to provide design and performance assessment information for consideration by mission designers who must quantify the radiation protection characteristics of their exploration trade space.

Aircraft Configured for Flight in an Atmosphere Having Low Density

The autonomous airplane can be folded in a confined volume, transported, and deployed in terrestrial or extraterrestrial venues.NASA Langley Research Center researchers have developed an airplane capable of being stowed in a confined volume and deployed in a high-altitude environment for extended-duration flight operations in a low-density atmosphere. Engineers, scientists, and end users can take advantage of this innovation that provides previously unattainable high-altitude flight operations. The airplane is delivered to a specified altitude folded in a container or rocket. Once released, the plane unfolds and executes a pull-up maneuver to stabilize altitude. In addition, the current suite of onboard scientific instrumentation includes magnetometers, a mass spectrometer, and variable-use cameras. NASA is seeking market insights on commercialization of the new airplane design, and welcomes interest from potential producers, users, and licensees.

Hot Isostatic Pressing of 60-Nitinol

The material 60-Nitinol (60wt%Ni-40wt%Ti) has a unique combination of physical properties, including high hardness, low apparent elastic modulus, and resistance to saltwater corrosion. These properties give the material tremendous potential for use in aerospace and defense-related components such as bearings, gears, and other apparatuses. Various methods of primary processing are being explored for fabrication of high-performance components that are free of metallurgical defects that might lead to premature failure. Hot isostatic pressing (HIP) is one process under consideration. The steps in the HIP process include (a) filling a sealed canister of the appropriate dimensions with powder, (b) heating the canister under vacuum to remove volatile and gaseous contents, (c) applying heat and pressure to the evacuated and sealed canister to consolidate the contents, and (d) removing the canister.

ViDAR Optical Radar Provides New Maritime Search Capability

ViDAR, developed by Sentient Vision Systems in Melbourne Australia, provides autonomous, real-time, wide-area search capability, optically, from unmanned aerial vehicles (UAVs) or manned aircraft. ViDAR, which stands for Visual Detection and Ranging, essentially acts as an optical radar, using high-megapixel video or infrared cameras to search the ocean over significantly greater operational coverage areas than can be achieved with current optical sensor approaches.
