2022 NASA Langley/Ames EDL Seminar for Summer Interns: Porous Microstructure Analysis (PuMA)
Abstract:
This talk discusses the capabilities of an open-source, NASA-developed software called Porous Microstructure Analysis (PuMA). The code was developed to provide a robust and efficient framework for computing material properties based on 3D microstructures. The development was motivated by advancements in X-ray microtomography, an imaging technology that can resolve the structure of a material at a sub-micron scale, in 3D and even in 4D (over time). At NASA, this technique has provided unprecedented insights into materials relevant for different missions, from heat shields, to parachute fabrics, to meteorites and other advanced composites. PuMA provides the ability to compute a comprehensive spectrum of material properties, from the most fundamental geometric features of a microstructure, to advanced anisotropic thermo-elastic and chemical properties. In addition, the software can generate artificial microstructures, including complex fibrous woven and non-woven geometries, allowing to perform optimization studies that inform the design of new materials.

A Digital Classification System to Assess Project Failures
Abstract:
Failure classification schemes are often used to categorize events that cause failures in projects. Despite the frequent publication of studies on project failure and success classification, there has been no analysis of failure classification schemes. Specifically, an open question concerns the similarities and differences of failure classification schemes between and within disciplines. Answering this question will provide insight into the applicability of a scheme across a range of disciplines and the challenges that may exist when multiple disciplines are collaborating on a project. Understanding the contents and nature of failure classification schemes is critical to improving theoretical study and practical implementation of schemes on projects.
The research presented in this presentation identifies 400 failure classification schemes through a systematic review, extracts over 4000 perceived causes of failure from the schemes as meta-data, and analyzes the schemes with a focus on disciplinary differences in the perceived causes of failure. Meta-analysis of the perceived causes of failure in the 400 failure classification schemes identifies that the content of failure classification schemes are diverse, both within and across disciplines. Significant differences are shown between schemes used in different disciplines. Within disciplines, the schemes show patterns in the perceived causes of failure that appear most frequently and there are some common perceived causes of failure among many disciplines. The findings of the research conclude that caution must be taken if applying a scheme across multiple disciplines.

Arizona Geology Field Trip
Discipline: Environmental Control/Life Support
A variety of hardware developers, crew, mission planners, and headquarters personnel traveled to Gila Bend, Arizona, in February 2008 for a CxP Lunar Surface Systems Team geology experience. Participating in this field trip were the CxP Space Suit System (EC5) leads: Thomas (PLSS) and Ross (PGS), who presented the activities and findings learned from being in the field during this KC. As for the design of a new spacesuit system, this allowed the engineers to understand the demands this type of activity will have on NASA’s hardware, systems, and planning efforts. The engineers also experienced the methods and tools required for lunar surface activity.

Electromagnetic Thermocouple (TC) Anomaly Mechanisms During Atmospheric Entry
Thermocouples (TCs) are a critical diagnostic sensor for high enthalpy environments including Thermal Protection Systems (TPS) for atmospheric entry, hypersonic wind tunnels, and arc jet test facilities. They are used for both evaluating facility environmental conditions (enthalpy, and heat flux) as well as for measuring in-situ material thermal response under test conditions (thermal conductivity, heat capacity, etc.). Consequently, accurate TC measurements are fundamental for both material and facility Verification and Validation (V&V). However, a number of electromagnetic TC anomalies have been observed in both ground tests and flight instrumentations. These anomalies are caused via various coupling mechanisms: surface voltage coupling, Hall effect currents, and RF rectification. All of these mechanisms can, if unaddressed, result in obviously compromised results or worse, non-physical measurements which appear reasonable. This talk will provide an overview of each of these anomaly mechanisms and discuss ongoing efforts to quantify and mitigate them.

FAA Overview: Software Certification for Avionics
Project: NASA Small Business Innovation Research (SBIR): Intelligent Information Processing System for Enhanced Safety in the NAS
Project Acronym: IIPS
Technical Abstract: IIPS is an information-centric, decision support, action-monitoring tool that focuses on information disconnects between actors or systems in a well-defined context and resolves those disconnects through progressively adaptive notifications. IIPS can also adapt to situations where information overload can saturate communications channels and overload the decision maker by providing the most relevant information at the most opportune time. The system goals include to improve safety performance for high-reliability flight systems, to permit scalable application from the flight deck to the systems operating at the level of the National Airspace System, and to permit easy integration of multiple disparate information sources using an open system architecture by using techniques which permit delaying unnecessary system constraints throughout the development process.
One of the Technical Objectives (TO) for IIPS namely, TO #4 is to Identify and formalize the software development requirements for eventual deployment to an environment requiring FAA certification.
The presentation provided here is the outcome of research associated with this TO #4. Some of the information provided here is common to any FAA certification specifically associated with software design assurance and hence is provided in this forum for information sharing.

Generation Y Perspectives
Discipline: Environmental Control/Life Support
Are you familiar with the famed Generation Y, or “Gen Yers?” Generation Y is projected to be 47 percent of the workforce by 2014. They were born roughly between 1977 and 2000, but that is definitely not their only defining factor. But who is this group, and what do they have to do with the future of the space program and the Johnson Space Center (JSC)? During 2007, a group of Gen Yers at JSC participated on a committee to address the NASA Headquarters strategic communications plan. Garret Fitzpatrick, along with his co-authors, created a presentation to share the Gen Yers’ perspective on their generation in conjunction with the strategic communications strategy released. This knowledge capture (KC) event is that presentation.

Getting Better at Getting Better: Caring and Candor in Feedback Conversations
Simultaneously improving performance and relationship in feedback conversations can be challenging. It is easier to focus just on performance (with confronting feedback that can harm the relationship) or just on the relationship (by sugar-coating the feedback). This session draws on cross-industry insights from research on learning from accident and error in high-hazard chemical processing and nuclear power, and on feedback and debriefing challenges in clinical care. The session illuminates 1) why it is so hard to hold the polarities of candor and caring at the same time, 2) the internal “ninja mind-training” needed to do so, and 3) a method of advocating for one’s own point of view while exploring other people’s that can be used advance learning and performance in conversation or email. The session blends didactic and experiential approaches to understanding and mastering the approach.

Learning From All Operations: Conceptual Framework
This webcast discusses the Flight Safety Foundation conceptual framework and common language for safety learning. The new framework is needed because the existing language of safety is predominantly built around learning from failures and cannot express learning from success. However, the new framework is unitary - it is not just a new framework to learn from success but it is an integral framework to learn from all that happens. The integral nature of the framework has also another dimension - it allows the relationship between safety and system objectives like efficiency to be made explicit. This lays the foundation of an approach that can best balance safety and system objectives like efficiency and sustainability.

Microfluidic Sensing Systems to Study and Seek Microbes Beyond Earth
Abstract:
We develop miniaturized integrated bio/analytical instruments and platforms to conduct economical, frequent, autonomous life-science experiments in outer space. The technologies of our multiple “free-flyer” cubesat missions are the basis of a rapidly growing suite of miniaturized biologically- and chemically-oriented instrumentation now enabling a new generation of in-situ space science experiments. Over the past decade, our missions have included studies of space-environment-related changes in gene expression, drug dose response, microbial longevity and metabolism, and the degradation of biomarker molecules. The science and technology of the GeneSat (2006) and BioSentinel (2022, via Artemis-1) missions will be highlighted in the context of conducting biological and chemical experiments in outer space using miniaturized integrated systems.
We also adapt and apply our spaceflight-compatible microfluidic and bioanalytical technologies to the challenge of finding molecular and structural indications of microbial life on the so-called icy worlds of our solar system, particularly the moons Enceladus and Europa. The Sample Processor for Life on Icy Worlds (SPLIce) system, a microfluidic sample-processing “front end” to enable autonomous detection of signatures of life and measurements of habitability parameters on icy worlds, will be described. SPLIce is under development to support several mission scenarios, including a fly-through of Enceladus’ icy plumes, expected to yield ~ 2 µL of ice particles, and a Europan lander, the sampling system of which is anticipated to deliver 1 – 5 mL of icy solids for analysis.

The Path to Detecting Extraterrestrial Life With Astrophotonics
Abstract:
Astrophysical research into exoplanets has delivered thousands of confirmed planets orbiting distant stars. These planets span a wide range of size and composition, with diversity also being the hallmark of system configurations, the great majority of which do not resemble our own solar system. Unfortunately, only a handful of the known planets have been characterized spectroscopically thus far, leaving a gaping void in our understanding of planetary formation processes and planetary types. To make progress, astronomers studying exoplanets will need new and innovative technical solutions. Astrophotonics -- an emerging field focused on the application of photonic technologies to observational astronomy -- provides one promising avenue forward. In this paper we discuss various astrophotonic technologies that could aid in the detection and subsequent characterization of planets and in particular themes leading towards the detection of extraterrestrial life.
About the Speaker:
Nemanja Jovanovic received his Ph.D. in laser physics from Macquarie University in 2010. He worked as a postdoc. on astrophotonics at the Australian Astronomical Observatory until 2012. He moved to Subaru Telescope where he was part of the SCExAO high contrast exoplanet imaging instrument team until 2017. Currently, Nemanja is the Optics and Systems Group Lead at Caltech developing advanced exoplanet instruments for the largest ground based telescopes while leading several technical developments in astrophotonics.

Thermal Glove Wrist-Hand Orthoses and Rheumatoid Arthritis
Rheumatoid arthritis (RA) is an autoimmune disease affecting nearly 1% of the world’s population with symptoms such as inflammation, pain, and reduced strength. Physicians and scientists work to develop pharmaceuticals and medical devices aimed at decreasing the symptoms associated with RA to better the lives of those affected. One of the most recent developments is the addition of thermal therapy gloves to the array of upper limb orthoses available to patients with RA. It was hypothesized that this study will show that orthoses in the form of thermal therapy gloves are beneficial to the patients by reducing symptoms such as pain and allowing them an increased range of motion and overall hand functionality. Patients in stage 2 were recruited and asked to first complete a personal history survey including the Health Assessment Questionnaire (HAQ) and Pain Catastrophizing Scale (PCS). Range of motion tasks and the Arthritis Hand Function Test (AHFT) were completed to determine the effect of two thermal therapy gloves on the range of motion and activities of daily living. This webcast will give an overview of the pilot study, results, and suggestions for future studies.

Using PZT Sensors for Tank Health Monitoring and Propellant Mass Gauging
Abstract:
The technology in the presentation utilizes a random white noise vibration source to drive a transducer which acts as an actuator with identical transducers used as sensors based on PZT materials. The sensors are recorded and used to produce Frequency Response Functions (FRF) which indicate unique stiffness and mass information for tanks (or other structures) near real-time. The data also shows the level of the fluid with amplitude variations based on the change in vibration transmission coupling as the fluid transverses the inside tank opposite the transducers. All transducers are non-invasive, applied to a tank with adhesive allowing for measurements of many fluids including cryogenic and toxic fluids used on space vehicles. This presentation will describe the unique technology and propellant tank test results including low gravity sub-orbital flights.

Virtual Reality for Worksite Analysis Methods
Open to the Public
Recorded September 10, 2019
NASA Marshall Space Flight Center (MSFC) Human Factors Engineering (HFE) Team is implementing Virtual Reality (VR) into HFE analyses of various projects. MSFC HFE is responsible for the worksite analyses of the integration efforts of the Space Launch System (SLS) that will be performed at Kennedy Space center (KSC), as well as the HFE analyses of Deep Space Habitat (DSH) Concepts. There is a wide variety of tasks, and it is important to verify that the vehicle can be integrated at KSC early in the design process. If the ground support crew cannot complete the task, access the parts of the elements that require integration, or if other hardware may be damaged during such access, redesign efforts have to be implemented. MSFC HFE is responsible for this verification and has used methods such as drawing inspection, observation of tasks performed on test articles, and building physical mockups that are sometimes used with Motion Capture (MoCap). In addition, VR analyses are now being utilized for a faster analysis early in the process that can impact design before drawings are finalized and funds are allocated for physical mockups. This technology does not replace the need for physical mockups in most cases, but rather improves the design maturity of the physical mockup. All of these methods are used in tandem to perform HFE assessments at NASA MSFC.
