Satellite launches experience approximately one deployment failure every two years. These failures include a solar array or antenna that fails to deploy because it is stuck due to a mechanism failure, or is snagged by a cable or thermal blanket. Knowledge of the exact circumstances of the deployable failure...

Afixed geometry device has been developed to promote boundary layer transition and generation of streamwise vorticity, and is capable of withstanding entry heating environments for the Space Shuttle Orbiter. Designed to have a total height above the surface...

NASA’s Langley Research Center has developed a method for exfoliating commercially available hexagonal Boron Nitride (hBN) into nanosheets a few atomic layers thick. Currently, hBN has limited use because it is insoluble with limited dispersibility, despite hBN having excellent thermal...

Low-cost access to space demands durable, cost-effective, efficient, and low-weight propulsion systems. Key components include boost and upper stage rocket engine nozzles and extensions. Nozzle material options include ablatives,...

Advanced composite materials processable by cost-effective manufacturing play an important role in developing lightweight structures for future space and planetary exploration missions. With the growing demand for improved performance in the...

A unique binder was developed that exhibits a glass transition temperature of –100 °C, which is more than 50 °C lower than that of traditional HTPB (hydroxyl-terminated polybutadiene) and CTPB (carboxyl-terminated polybutadiene) binders. This innovation would be a solid propellant that would...

A method creates thermally healable composites using carbon nanotubes. Carbon nanotube microwave heating provides a pathway to overcome issues associated with electrical resistive heating networks. Carbon nanotubes embedded within a thermally reversible polymer can be...

The Toughened Uni-piece Fibrous Reinforced Oxidation-Resistant Com posite (TUFROC) allows for much more affordable and sustainable operations involving Space Launch Services and other systems that utilize Earth reentry vehicles. TUFROC has an exposed surface design and...

Reducing the cost and weight of launch structures is essential to meeting NASA goals for reliable access to space. Currently, separate systems are used for structure and pressure containment, cryogenic insulation, and high-temperature insulation. One way...

The Lighting System to Improve Circadian Rhythm Control was designed and built to help regulate the sleep cycles of astronauts working on the International Space Station (ISS) and during long-duration spaceflight. In space, the lack of a...

High-intensity focused ultrasound (HIFU) is a rapidly developing medical technology that relies on focusing acoustic waves to treat remote tissue sites inside the body without damaging intervening tissues. HIFU can be used to treat benign and malignant tumors, dissolve blood...

A new method to screen the gastrointestinal (GI) tract for radiation sensitivity and radiation-induced gene damage has a number of applications. This technology could be used to assess radiation susceptibility in individuals, such as astronauts, nuclear reactor workers, those undergoing...

Biologic scaffolds composed of extracellular matrix material (ECM) have been used for the repair of a variety of tissues including the lower urinary tract, esophagus, myocardium, and musculotendinous tissues, often leading to tissue-specific constructive remodeling with...

There are continuous concerns about the possibility of nuclear and radiological terrorism or accidents that may result in mass casualties in densely populated areas. To guide medical personnel in their clinical decisions for effective medical management and treatment of exposed individuals, biomarkers...

The current method of emulsifying tissue employs focused ultrasound with microsecond pulses and cavitation. This invention emulsifies soft tissue using a mechanism of ultrasonic atomization inside gas or vapor cavities. The method of non-invasively...

The Lunar Reconnaissance Orbiter (LRO) employs many advanced innovations developed at NASA’s Goddard Space Flight Center and in collaboration with other organizations. The applications and benefits for these technologies are advantageous for many other...

NASA’s Langley Research Center is developing Traffic Aware Strategic Aircrew Requests (TASAR). TASAR features a cockpit automation system that monitors for potential flight trajectory improvements and displays them to the pilot. These wind-optimized flight trajectory changes are...

Physical manufacturers have been taking advantage of mass manufacturing ideas for a long time, increasing their productivity, cutting their costs, and ensuring the quality and uniformity of their products. Now, this idea is being applied to...

NASA’s Langley Research Center has developed a technology at the forefront of a new generation of computer and video game environments that trains valuable mental skills, beyond eye-hand coordination, for the personal improvement, not just the diversion, of the user.

Graphical modeling tools have gained popularity within engineering communities, but such languages are known to suffer from lack of semantics and mathematical rigor. By supporting a graphical language with a textual language, and mapping graphical models to the textual language, one ensures proper unique semantics of the...

In the 2006 timeframe NASA’s Constellation Program was looking to address several issues with the way Problem Reporting data had been collected for the Shuttle Program including multiple systems across groups and centers (20+ for Shuttle), inconsistent schemas and...

The objective of the current innovation was to develop a simple but accurate method for predicting boundary layer transition that would include the growth characteristics of laminar boundary layer disturbances while requiring only the pressure distribution over an aerodynamic...
