As documented by the Human Research Program, there is a need for tools to aid in assessing habitability in space vehicles/habitats. Currently, human factors and habitability feedback is collected during post-mission debriefs that may occur up to several months following the end of a mission....

NASA has a need to determine the distribution of dark matter around planets like Earth. Doing so necessitates the ability to repeatedly solve the geodesic equation in simulations of weakly interacting particles streaming through bodies described by a Schwarzschild metric. Geodesolver numerically solves the...

Newly developed two-dimensional (2D) materials such as graphene — which consists of a single layer of carbon atoms — have the potential to replace traditional microprocessing chips based on silicon, which have reached the limit of how small they can get. But engineers have been...

Smartphones and sensors have produced a treasure trove of pictures, many tagged with pertinent information identifying content. Using this vast database of cross-referenced images, convolutional neural networks and other machine learning methods have revolutionized the ability to quickly identify natural...

NASA’s Goddard Space Flight Center has developed a method to collect suspicious data and analyze them without extensive costs. A common challenge in complex computer systems is the identification of unauthorized use, which can be...

NASA has developed a method and system that provides selective access to different portions of a database by different subgroups of database users. In this system, two or more members of a given access subgroup can simultaneously edit a document accessible to each member. This database system provides...

The evolving nature of the Internet will require continual advances in authentication and confidentiality protocols. Nature provides some clues as to how this can be accomplished in a distributed manner through molecular biology. Cryptography and molecular biology share certain aspects...

A major drawback to 3D printing is the slow pace of the process, which ensures details are reproduced accurately. The pace of 3D printing is one of the factors that has prevented the technology from finding a broader audience. A new algorithm was developed that boosts the speed at which the printers operate.

This software reads MLS Level 1 products — the Earth Observing System (EOS) Microwave Limb Sounder (MLS) calibrated measurements of microwave radiance products and operational meteorological data — and produces a set of estimates of atmospheric temperature and composition. The software...

NiceC is an improved version of ANSI C. It attempts to clean up C as much as possible using syntax translation. A type checker for NiceC is under development. The NiceC programming language is translated to, and fully compatible with, ordinary C. Thus it can be used as a drop-in replacement for C. The main benefits of...

Project planning data collected by the Analysis, Planning, and Tracking (APT) system during the planning cycle previously was available to users via an email request to a data administrator who would pull data from the database, format as requested, and respond via email. Access to the data was limited by the availability of the data...

A new sensor picks up signatures of tributyl phosphate, a solvent used to enrich uranium, including for use in a nuclear weapon. Enzymes can detect tributyl phosphate signatures, but the lifespan of the enzymes is too short to make them practical for sensors.

Computers and automated systems have accelerated productivity and improved quality and reliability for nearly everything, and are destined to take on increasing roles as time moves on. One major limiting factor for automated systems is their inability to categorize and recognize...

The Soil Moisture Active-Passive (SMAP) Project Spacecraft Flight Software controls all aspects of command and data handling (CDH) in the SMAP spacecraft. Required capabilities include uplink and command, telemetry and downlink, vehicle attitude control, science instrument control,...

This software partitions a dataset into clusters of data using the Deterministic Annealing algorithm, a more sophisticated clustering technique than usually available in scientific and commercial software. The results provided are deterministic, i.e. unique (within the machine precision tolerance), whereas results...
