Probiotic Therapy for Astronauts, and During Radiation Therapy

Ames Research Center, Moffett Field, California 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 radiation therapy for cancer, and others who may be or have been exposed. The method could also be used to develop and test various probiotic regimens to repopulate the GI tract microbiome to deliver more radiation resistance, or more rapid healing following radiation exposure.

Methods of Manufacturing Bioactive Gels from Extracellular Matrix Material

Lyndon B. Johnson Space Center, Houston, Texas 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 minimal or no scar tissue formation. Although use of ECM as scaffolds for preclinical and clinical tissue engineering and regenerative medicine approaches to tissue reconstruction is very promising, challenges remain in the process to manufacture bioactive gels from ECM that retain their bioactivity.

Multi-Parameter Biodosimetric HemoDose Tools

Lyndon B. Johnson Space Center, Houston, Texas 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 are usually applied to examine radiation-induced biological changes to assess the severity of radiation injury. Among these, peripheral blood cell counts are traditionally regarded as the most practical and rapid diagnostic indicators.

Soft-Tissue Emulsification Using a Mechanism of Ultrasonic Atomization Inside Gas or Vapor Cavities

Lyndon B. Johnson Space Center, Houston, Texas 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 treating tissue includes pulsing ultrasound energy from the ultrasound source toward the target site in the tissue. The ultrasound source is configured to emit high-intensity focused ultrasound (HIFU) waves. The target site comprises a pressure-release interface of a gas or vapor cavity located within the tissue. The method continues by generating shock waves in the tissue to induce a lesion at the target site. It additionally includes characterizing the lesion based on a degree of at least one of a mechanical or thermal ablation of the tissue. This work was done by Oleg Sapozhnikov, Michael Bailey, Tatiana Khokholova, Vera Khokholova, and Julianna Simon of the University of Washington for Johnson Space Center. NASA is seeking partners to further develop this technology through joint cooperative research and development.

System and Method for Transferring Telemetry Data Between a Ground Station and a Control Center

Goddard Space Flight Center, Greenbelt, Maryland 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 industries as well. One of those technologies is the Space Link Extension Return Channel Frames (SLE-RCF) software library. This software library enables a mission control center to receive telemetry frames from a ground station. The technology implements the SLE-RCF protocol as defined by the Consultative Committee for Space Data Systems (CCSDS). Software routines can be reused from mission to mission.

Method and Apparatus for Generating Flight-Optimizing Trajectories

Flight path and altitude modifications are pre-cleared of potential conflicts with other known airplane traffic, weather hazards, and airspace restrictions. Langley Research Center, Hampton, Virginia 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 pre-cleared of potential conflicts with other known airplane traffic, weather hazards, and airspace restrictions. The TASAR is to improve the process in which pilots request flight path and altitude modifications due to changing flight conditions. Changes may be made to reduce flight time, increase fuel efficiency, or improve some other flight attribute desired by the operator. Currently, pilots make such requests to air traffic control (ATC) with limited awareness of what is happening around them. Consequently, some of these requests will be denied resulting in no flight improvements and an unnecessary workload increase for both pilots and ATC. The TASAR technology provides pilots with recommended flight path and altitude improvements that are more likely to be approved by ATC.

Systems, Methods, and Apparatus for Developing and Maintaining Evolving Systems with Software Product Lines

Goddard Space Flight Center, Greenbelt, Maryland 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 software production so the same benefits can be reaped in that field.
