NASA’s Marshall Space Flight Center innovators have developed several new designs and methods of fabrication for composite and composite-overwrapped tank vessels that help significantly improve their structural integrity against impact, abrasion, harsh environments, and fire. Several...

Innovators at NASA’s Glenn Research Center have created exciting new developments in thermal barrier coatings, both in the chemical compositions of the coatings and in the process by which they are applied. NASA’s researchers have developed a revolutionary bond coat system that improves the...

NASA Goddard’s scientists have developed a novel, volatile organic compound (VOC)-free system for cleaning tubing and piping that significantly reduces cost and carbon consumption. The innovative technology enables the use of deionized water in place of costlier...

Researchers at NASA’s Marshall Space Flight Center have developed a system that reduces the entrapment risks associated with a pool or spa’s recirculation drain. The technology prevents hazards caused by suction forces on the body, hair, clothing, or other articles. Employing a novel configuration of...

Shrinking or contracting light guides is a problem when photomultiplier tubes (PMTs) are glued to the guides. If there is no way to allow movement of the PMTs, when the temperature goes down, the light guide contracts and breaks the glue joint. The PMTs cannot be left loose to rattle around inside the detector....

Particle shape is a very important property in many fields of research, and with many practical, diverse, and commercially important applications including pharmaceuticals, civil engineering, metallurgy, health, and food processing. Many of the methods used to evaluate the shapes of...

Libibvpp provides a C++ wrapper API to the libibverbs library. Libibverbs is the OpenIB library that provides the Verbs API for programming Infiniband hardware. It is written in C and provides a C API. Because the API is in C, it is up to the library user to do explicit resource management for the objects created through the API.

The demands for high-sensitivity and high-resolution radiometry have recently led the science community to examine the use of large deployable mesh reflectors, which have heretofore only been used in telecommunications applications.

Recurring Slope Lineae (RSL) are low-albedo features that appear and disappear seasonally on Martian slopes. They provide distinct surface markers that are thought to result from the activity of subsurface water. Reliable characterizations of RSL activity are needed to test this hypothesis....

JPL Operations Engineers (Operators) need to interact with their telemetry to assess the health of and successfully operate a spacecraft or rover. Operators must analyze the immediate data for health and understand the current state of these complex systems, but they also must be...

The technique of synthesizing state-machine-based hybrid controller flight software (FSW) from formal specifications is demonstrated utilizing two simple controller examples (i.e. a simple thermostat and a simple autonomous vehicle). Formal requirements for these...

The Intermediate Palomar Transient Factory (iPTF) is a visible-spectrum astronomy survey aimed at detecting “transient” events such as supernovae. Every night, a telescope at the Palomar observatory collects images of various regions of the sky and compares them to a set of reference...

Source code analysis typically requires the use of expensive and difficult-to-configure tools that support only a predefined set of standard checks. In some cases, it is possible to add customized checks, but doing so can be laborious and requires a deep understanding of each tool’s internal...

Each December, we ask our readers to cast their vote for the annual NASA Tech Briefs’ Readers’ Choice Product of the Year Awards. Each month, our editors choose a Product of the Month that has exceptional technical merit and practical value for our design engineering readers.
