| Duration | 58:10 |
| Tags | None |
Abstract:<br>Understanding an individual’s metabolic rate is important in a wide range of terrestrial and extraterrestrial applications. For extraterrestrial applications, devices to measure metabolic rate should be compact, low power, and require little maintenance and/or calibration. This presentation discusses the effort to develop a new portable metabolic device (PUMA - Portable Unit for Metabolic Analysis) at the NASA Glenn Research Center. PUMA is a battery-operated, wearable unit to measure metabolic rate (minute ventilation, oxygen uptake, carbon dioxide output and heart rate) in a clinical setting, in the field or in remote, extreme environments. The critical sensors in PUMA that measure oxygen, carbon dioxide and ventilatory flow are located close to the mouth and sampled at 10 Hz to allow intra-breath measurements. The engineering efforts to develop PUMA will be presented, followed by limited validation studies of the final device. Finally, the application of PUMA and the underlying technologies for a range of applications will be presented.

Refresh this page if not yet visible.<br>- Please submit questions as they arise rather than waiting until the end.<br>- Enjoy!<br><br>Abstract:<br>“Spacecraft large enough for crew to move around inside them have traditionally used handrails and foot restraints to enable crew mobility. The mass of this hardware can become significant in large spacecraft such as the Common Habitat. Additionally, handrails and foot restraints in a multi-gravity habitat are trip hazards when the habitat is in a gravity environment. Further, ISS crew have noted risks of breaking ankles and wrists when using handrails for translation and have noted places where not enough handrails are present. Robotic gecko-derived grippers developed by JPL to retrieve satellites can be adapted to crew-worn pads that can adhere to surfaces to enable crew translation in microgravity. <br><br>This technology will help to eliminate the need for handrails and foot restraints for mobility in crewed microgravity spacecraft cabins. It has the potential to achieve significant mass reductions in future space habitats, with application to suborbital flight, LEO, cislunar space, interplanetary space, the Moon, and Mars. Additionally, it can prevent crew injury and discomfort. Project goals and objectives are to prepare gecko uniform prototypes for use in multi-gravity testing and conduct initial investigations into human factors of postures and motions needed for intravehicular activity (IVA) translation and restraint in multiple gravity environments, without the use of handrails or foot restraints. Gecko grippers have been tested for use as robotic end effectors terrestrially, on microgravity aircraft, and aboard the ISS.<br><br>Using the grippers as a body-mounted system to achieve IVA crew mobility is a new application that has not been pursued outside of this effort. This work will continue paper studies performed by NASA student interns by developing physical prototypes of spacecraft crew uniforms with gecko-derived body-mounted grippers. Clothing prototypes may include long sleeves, short sleeves, long pants, shorts, gloves, and/or booties equipped with gecko gripper pads. Forward work is to test these uniforms in a 1g environment to verify that the design does not introduce obstructions, trip hazards, or other consequences when used in terrestrial gravity. Based on the 1g test results, the uniform prototypes will be refined, and a test plan developed for testing at 0g, (1/6)g, and (3/8)g.

Abstract:<br>A rapid mission analysis tool is developed to support the ongoing design of a Lunar Transit trajectory of the Power and Propulsion Element (PPE) between a Medium Earth Orbit (MEO) parking orbit and a lunar L2 southern Near Rectilinear Halo Orbit (NRHO). A parameterization is developed by which the Lunar Transit can be analyzed in the context of varying vehicle mass, solar electric propulsion (SEP) configurations, and solar array power output. A rapid and novel mission analysis tool enables a wide array of these trade analyses to be completed without the need for extensive computing resources or time.

| Tags | None |
<br>Abstract:<br>Rocket engines and their components are tested to validate models and reduce mission risks. The quality of the data collected largely depends on the types of signal conditioning and sensors used in the process. Since the 1960's, Stennis Space Center (SSC) has been NASA's leading center for testing Rocket Stages, Rocket engines and rocket engine components. Throughout this time, SSC has developed best practices on how to deal with sensor shortcomings and increase their reliability. This paper explains the operation of the most common sensors used, their pros and cons, and their uncertainties. Additionally, it covers the in-place calibration of the facility propellant flowmeters which cannot be removed and sent to be calibrated at a lab on a regular basis.

Abstract:<br>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.

NASA Marshall Space Flight Center is responsible for MAV and is working with the Jet Propulsion Laboratory and Lockheed Martin to complete this part of the multi-year campaign. Human Systems Integration (HSI) of the MAV is paving the way for HSI in unmanned missions, as MAV is one of the first projects to officially be mandated to have an HSI plan, as directed through NASA Procedural Requirements. The Marshall HSI lead has needed to be flexible and innovative, in the face of changing requirements and evolving management strategies. <br><br>The HSI plan has had to be adaptive to these changes, while continuing to be useful and valuable to the SE team and to project management. The fact that the project has continued to rely on the HSI approach, despite outside argument that this focus was unnecessary, has only proven the value of HSI in such systems. This presentation highlights the plan and the path that led to the current status.

This talk describes sizing of a lift-plus-cruise urban air mobility aircraft with all-electric, hybrid-electric, and turbo-electric propulsion systems using the Parametric Energy-based Aircraft Configuration Evaluator (PEACE) framework. The PEACE framework was developed at the Vehicle Systems, Dynamics and Design Laboratory (VSDDL) to allow sizing and performance analysis of novel configurations and propulsion system architectures. After assessing the sensitivities of the sized design to mission range and technology state-of-the-art, multi-objective optimization is performed using a genetic algorithm for a set of sizing scenarios.

Abstract:<br>As researchers develop new materials and systems, thermal transport is often key to performance, safety, and reliability. For instance, in battery cells, interfaces and low conductivity pathways can lead to high temperatures that can lead to thermal runaway. In portable and wearable electronics, limited heat dissipation pathways lead either to temperatures that require throttling device performance or that degrade the system. The Marconnet Thermal & Energy Conversion (MTEC) Lab focuses on (1) the design, development, and validation of novel experimental metrology tools for characterizing multi-functional properties of materials across length and temperature scales; (2) enhanced understanding and control of fundamental transport and energy conversion mechanisms through multi-scale computational modeling; and (3) strategic, physics-based design and development of materials with multi-functional capabilities. <br><br>This talk will describe several recent examples from my group of engineering materials to achieve targeted performance objectives, along with the development of new metrology tools for understanding thermal transport. We build from steady state to transient and high-powered heat dissipation systems for electronics cooling and other applications illustrating combined experimental and modeling approaches. These current and past projects provide a foundation for our new research directions related to thermal transport and energy storage.<br>

Abstract:<br>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.<br> 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. <br>

Refresh this page if not yet visible.<br>- Please submit questions as they arise rather than waiting until the end.<br>- Enjoy!<br><br>Abstract:<br>Growing numbers of cities and companies are beginning to deploy state of the art technologies and services such as autonomous cars, robot taxis, delivery- and maintenance-robots, moving information kiosks and others. As a consequence, it is expected that the public space where people, cars, and robotic systems interact will need to undergo transformations to accommodate these new entrants. This accommodation is not only related to the technology per se, but also involves people’s grasp of how these “automated beings” are to act, interact and move (i.e., “behave”) in the public space. One of the most crucial aspects of this deployment involves defining new “rules of the road” that embody ethical considerations. With the entry of robotic “beings” into the public space and focus on ethical behavior and its practical encoding in the vehicle’s software, there is an opportunity to make tomorrow’s public space more equitable and accommodating for all. <br><br>This talk presents a framework and methodology for developing ethical decision making in the context of autonomous vehicle behavior (part of a soon to be published ISO standard 39003). One of the advantages of this methodology is that it can take any set of ethical values (e.g., the United Nations’ universal values, the Bioethics code of conduct, etc.). The selected set act as general guidelines for rule development and criteria for formal evaluations. I will discuss the issues involved in defining ethical rules for a variety of use cases such as lane changes in dense traffic, determining priority in vehicle-to-vehicle interactions, negotiations in ambiguous situations, and more. For each, I will describe the methodology and processes leading up to an “ethical” driving rule. I will also briefly touch on the philosophical “trolley problem” example and suggest a way to resolve it in the context of dynamic control systems.<br>

Refresh this page if not yet visible.<br>- Please submit questions as they arise rather than waiting until the end.<br>- Enjoy!<br><br>Abstract:<br>Redundant controls are ubiquitous in many aerospace domains, including aircraft, spacecraft, and launch vehicles. Multiple control effectors having different capabilities (e.g., reaction controls, aerosurfaces, and vectored engines) must be optimally allocated to achieve high-performance and robust vehicle control, while considering different constraints, cost, or performance metrics associated with various control mixing schemes. These can include force or deflection limits, rate limits, propellant usage or drag penalties, cross-axis coupling, uncertainties, or even servoelastic interactions. <br><br>This presentation introduces the fundamentals of control allocation theory, based on linear algebra and convex sets, using a handful of examples taken from the air and space vehicle domains. It is shown that even simple methods can provide verifiable and quantifiable performance benefits over ad-hoc approaches, and can support enhanced functions like fault tolerance and control reconfiguration.

Abstract:<br>The Europa Lidar Sensor Assembly (ELSA) is a multi-function lidar for landing on objects in our solar system of which we have limited topographic knowledge. Europa is an example object of high interest due to the hypothesis that a water ocean hides beneath its icy surface and possibly containing evidence of life; however, existing images of its surface we have are low-resolution, making it difficult or impossible to plan a safe landing. The ELSA system being presented is designed to provide altimetry from 10 kilometers to 10 meters, a coarse Digital Elevation Model (DEM) generated at a 5-kilometer elevation for site selection, and fine DEM generated at a 500-meter elevation for hazard avoidance. ELSA utilizes a radiation hardened single photon sensitive Geiger-mode Avalanche Photodiode (GmAPD) array of detectors, dual green lasers with sub-nanosecond pulsewidth, and real-time Field-programmable Gate Array (FPGA) processing. Progress on the brassboard design and build, scheduled for field testing next year, will be presented.

Our world is changing rapidly, and work follows suit. Considering the traditional division of work in physical and mental labor, it is primarily physical labor that has been systematically analyzed and optimized over the last century. This made it possible to break down many manual tasks into small entities that could eventually be automated. This widespread automation is one of the main drivers of a changing world of work. While non-routine tasks have been considered fairly safe from automation in the past, recent advances in cognitive computing and artificial intelligence suggest that mental work might be next in line. In fact, some basic cognitive tasks have already been automated. A final frontier on the road towards ubiquitous automation, however, seems to be the generation of creative ideas. This suggests that the human capability to create will become increasingly important. <br><br>The present talk therefore aims to characterize creativity and its role in the modern workplace. Starting form a shared understanding of what creativity is, we examine the different areas in which human factors/ergonomics can support creative work. More specifically, we take stock in how creativity can be measured, analyze the pitfalls these types of measurement entail, and show how creativity support systems are now a staple in HMI Design. Concluding, human factors/ergonomics is recognized as particularly suited discipline to tackle creativity measurement and amplification in a human-centered way.

Topology optimization is able to provide unintuitive and innovative design solutions and a performance improvement (e.g. weight savings): In excess of 50% is not uncommonly demonstrated in a range of engineering problems. With the advances in materials and additive manufacturing, topology optimization is attracting much attention in the recent years. This presentation will introduce some of the latest developments in topology optimization in the context of design problems that experience a wide temperature range during its operation. In addition to the conflicting nature of thermal and mechanical effects on a structure, the heat transfer characteristics themselves are a function of the design.<br><br>They present a unique set of challenges to the optimization algorithm and the topology optimization formulation can have a critical impact on the final design and the achievable performance. The seminar will review the latest developments in studying the optimal thermomechanical structures by multi-scale and large-scale topology optimization where novel and unintuitive designs are obtained from the largest design space.<br>

Crowdsourcing data shows the method to be an outlier in effectiveness for back pain. To support posture training, we developed SpineTracker™ and PostureTracker™, two wearable devices which provide real-time posture feedback to the student. SpineTracker is a five sensor unit that accurately shows the shape of the lumbar spine; PostureTracker is a two sensor unit that helps students to catch themselves when they depart from a personal ideal. <br><br>During our presentation, we will give an introduction to the principles of the Gokhale Method and provide an overview of our research based on our wearables."<br>

Abstract:<br>Experimental aeroacoustic testing has undergone a radical transformation over the last 25 years with the development of novel microphone phased array measurement systems. These phased arrays are now routinely used in wind tunnel testing to identify the source and strength of radiated noise generated by aerodynamic models. They are also increasingly being used for the characterization of generated noise in full-scale flyover flight testing. This webcast will give an overview of the fundamentals of microphone phased array measurements. Examples of both ground test and flight campaigns will be given where the microphone array was the primary sensor system used to collect information regarding baseline acoustics and the effectiveness of noise reduction treatments for subsonic fixed-wing airframes.

Abstract:<br>Hydrogen has the highest specific energy of any fuel, is 74% of known mass in the universe, and reacts with oxygen to form water. As such, Humanity’s continued progress necessitates mastering hydrogen. 60 years ago, NASA’s Manned Spaceflight Management Council chose to develop the Saturn S-II and S-IVB LH2/LOx stages for the coming Apollo Missions to the Moon. Choosing liquid hydrogen may have been the deciding factor in mission success due to overlapping system synergies from faster transit to lighter-weight power from Bacon Cells and drinking water for the crew. Developing liquid hydrogen infrastructure sustained commerce for many decades beyond the Apollo Missions. Today, 30% of groceries in the US are moved via forklifts operating from this infrastructure. <br><br>Hydrogen will remain key in our clean energy future; whether mission architectures utilize chemical, fission, or fusion power, or we move goods via plane, train, truck, or boat. Fundamental technology advancements will be pivotal to this future. Hydrogen liquefier efficiencies remain only 30% of theoretically achievable and liquid hydrogen storage losses range between 7-40%, all but precluding missions to Mars. In this talk, I invite you to address these challenges via synergistic solutions enabled by modern manufacturing. For example, small, modular, efficient hydrogen liquefiers can be rapidly produced while fitting down the interstate, the column of an off-shore wind turbine, or an upper stage rocket fairing. Novel liquid hydrogen storage technologies can work with these cooler concepts to achieve Zero-Boil-Off in a variety of ways. The culmination of these developments has the potential to realize a sustainable energy future both on Earth and across the Solar System

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.

Abstract:<br>To better understand the atmospheric structure and dynamics on the Venus surface and provide input to climate models, there is a need to measure the wind velocity and direction on the surface and track changes over extended periods. A wind sensor based on a miniature drag-force anemometer is being developed to meet the challenges for wind measurements and operational requirements on the surface of Venus. The sensor materials are chosen to enhance durability and prevent reactivity with the Venus surface atmosphere. Advantages of this approach include that it is independent of variable heat transfer, has been matured in other harsh environment applications, and has a low mass and power requirement. Prototype drag-force anemometers were demonstrated, integrated with a high-temperature operational amplifier, recording transient effects in a simulated Venus surface environment. For multidirectional wind monitoring, the sensors are small enough to be deployed orthogonally as a three-dimensional array on a small arm or mast. This presentation describes the development and demonstration of this miniature drag-force anemometer integrated with high temperature electronics in a simulated Venus surface environment.

Traditionally, the negative unintended consequences of introducing new technologies into complex systems have not been explicitly assessed and mitigated. Recently, our understanding of how to identify, protect, and facilitate sources of resilience in a work system has advanced. In particular, there are lessons learned from two case studies of technologies: 1) voice loops, an auditory shared space that supported NASA Johnson communication and coordination, and 2) the introduction of bar coding in the medication administration process throughout the Veteran’s Health Administration. BCMA was designed to improve patient safety by reducing medication errors at the time of medication administration. <br><br>During and after implementation, there were unintended consequences on the ability of work systems to: 1) have a shared awareness of demands and deviations, 2) progressively respond to changing circumstances, 3) guide local control with policies and procedures, 4) flexibly adapt by reducing constraints on actions, and 5) coordinate across the system.

The Entry, Descent, and Landing (EDL) phase of a scientific mission to a planetary body involving atmospheric flight is critical because the spacecraft must survive the extreme environment it encounters as it traverses the atmosphere. Mission designers must ensure the spacecraft's Thermal Protection System (TPS) can adequately protect the spacecraft, and the scientific payloads it carries. The EDL sequence is often regarded to be among the riskiest parts of the mission because there is little to no opportunity to take corrective action if a problem or anomaly is encountered. The Thermal Protection System is a single point of failure, and its design involves a robust sizing and margins process. Engineering instrumentation embedded within the Thermal Protection System provides valuable flight data to support verification and validation of analysis and simulation tools that are used for TPS design. <br><br>This presentation will give an overview of in-situ EDL instrumentation used in atmospheric entry vehicles. Examples of different sensor types and recent instrumentation flown on NASA missions within the past decade will be presented, including the instrumentation suites flown on the Mars Science Laboratory, Mars 2020, and Orion Exploration Flight Test-1 missions. In addition, instrumentation that will fly on the Artemis 1 and 2, and Dragonfly missions will be described. Furthermore, sensor measurement accuracy and/or resolution for the current state-of-the-art, along with future needs, will also be discussed.

What are the causes of failure? In this most unforgiving of human endeavors, the surprising answer is that the “rocket science” isn’t the hardest part. Ultimately, it comes down to how we think about the work, and the human behaviors that shape how we do the work. Success is critically dependent on such variables as whether or not we maintain a balance between ego and humility, and whether we remain open to new information that conflicts with our world view. It hinges on whether we indulge—even unconsciously—in all-too-common human behaviors like false perception of risk, hubris, groupthink, and that bane of technical organizations called the Not Invented Here syndrome. In spaceflight, we cannot afford those indulgences: They can be fatal. Fortunately, there are time-tested modes of thinking and behaviors that enhance our chances for success, when we choose to rigorously employ them.

The Mars Ascent Vehicle (MAV) will be the first vehicle to perform an ascent from the surface of another atmospheric planetary body outside of the Earth‐Moon system. Significant light‐time delay requires complete autonomy of flight throughout ascent, and naturally a high level of reliability is desired in both MAV’s hardware and software subsystems. The MAV Guidance, Navigation and Controls (GNC) team and the MAV Flight Software (FSW) team have partnered together to improve the efficiency of algorithm integration onto the MAV flight processor, and to increase confidence that said integration is successful and without human error. An interface architecture is proposed for the GNC suite that allows both the guidance and navigation subsystems to provide code algorithms directly in C++, and the controls subsystem to provide MATLAB Simulink auto‐coded algorithms. <br><br>Several continuous integration/deployment (CI/CD) methodologies have been considered for ease of transition of algorithm code from the GNC team to the FSW team. The GNC/FSW teams also worked together to develop a cFS‐friendly wrapper which abstracts the integration of the GNC algorithm code into an interface‐level API that is compatible with cFS. Several iterations of vehicle GNC code have been produced between the GNC/FSW team’s partnership, and this strong interface between these two teams have allowed the GNC/FSW teams to greatly increase confidence of efficient and error‐free implementation of the GNC code onto MAV for a successful flight.<br>

Architecture and the built environment have the power to influence and shape the way humans think, feel and ultimately perform. Those creating these environments have the power to ensure that the human impact is not only positive, but also one that contributes to habitability and mission success. Despite living in a fast-changing world - whether it be technology, social structures, climate, or human-centric factors - our built environment changes very slowly. This statement is valid on earth, and holds further significance in space. An interdisciplinary human centered design approach, offered by a diverse team of experts, could potentially aid in creating environments that meet the different goals, risks, challenges and astronaut personas for a specific mission. This talk will explore the potential influence of human centered design solutions on habitability and mission success from the perspective of both earth and space. From the efficiency of a standardized common solution to a tailored approach, the talk explores how human factors are incorporated into each

On Demand Manufacturing of Electronics (ODME) is a project that is part of NASA’s In Space Manufacturing suite of projects that is developing on-demand manufacturing capability for the International Space Station and beyond. These capabilities will include on demand manufacturing of metals, electronics, sensors, and the ability to reclaim and recycle for long-term sustainment. ODME is developing new materials and processes for additively manufacturing electronics and sensors in a microgravity environment. The new capabilities will allow NASA to replace and upgrade existing electronic components, and also upgrade systems and sensor networks with on-demand printing capabilities. This is an enabling capability for long-term habitation as well as long-range space missions.<br><br>
