NIA Associate Principal Engineer Presents at 153rd AES Convention

Menachem Rafaelof, Associate Principal Engineer at the National Institute of Aerospace (NIA), presented “An Algorithm for Statistical Audibility Prediction (SAP) of an Arbitrary Signal in the Presence of Noise” during the 153rd Audio Engineering Society (AES) Convention in New York City. This workshop presented the first opportunity to present this ongoing work outside NASA to attendees interested in psychoacoustics, audibility prediction and predicting noise due to the operation of Urban Air Mobility (UAM) vehicles and its impact on the public attended this workshop.

Abstract:  
A method for predicting the audibility of an arbitrary time-varying noise (signal) in the presence of masking noise has been developed. The statistical audibility prediction (SAP) method relies on the specific loudness, or loudness perceived through the individual auditory filters, for accurate statistical estimation of audibility vs. time.  More recent development has focused on derivation and inclusion of frequency-dependent correction factors in SAP’s model to account for the ability to hear signals below the level of the masking noise.  Audibility prediction vs. time is intuitive since it captures changes in audibility with time as it occurs, which is critical for the study of human response to noise. Concurrently, time-frequency prediction of audibility may also provide valuable information about the root cause(s) for audibility useful for the design and operation of sources of noise. Empirical data, gathered under a three-alternative forced-choice (3AFC) test paradigm for low-frequency sound, has been used to examine the accuracy of SAP.

NASA eClips™ Publishes Newly Revised Engineering Design Packets and Implementation Guide

The National Institute of Aerospace’s Center for Integrative STEM Education (NIA-CISE) used an intentional design approach to create a packet meeting the needs of learners and educators. NIA-CISE invited a diverse group of formal and nonformal educators from the NASA eClips Advisory Boards to have a seat at the table to help update the Engineering Design Packets (EDP). The collaboration with this group of educators was valuable in the redesign process and resulted in the creation of a set of NASA eClips resources for elementary and secondary classes.

Another group of educators from across the United States was selected to pilot the EDPs. Dr. Bradford Davey of Technology for Learning Consortium, Inc. surveyed the pilot groups about their experience and collected anecdotal data from learners. NIA-CISE Education Team used the feedback provided by educators to improve the packets before publishing for the 2022-2023 school year. The EDPs are editable and can be used with any engineering design challenge.

The Education Team from NIA-CISE includes Dr. Sharon Bowers (Senior STEM Educator), Joan Harper-Neely (STEM Education Specialist), and Betsy McAllister (NIA Educator in Residence).

NASA eClips™ Partners with NASA Earth Science Education Collaborative to Develop NASA Spotlite Design Challenge: Land Detectives

NASA eClips has partnered with NASA’s Earth Science Education Collaborative (NESEC), The GLOBE Program, and GLOBE Observer to co-develop and promote the newest NASA Spotlite Challenge, Land Detectives. As NASA Land Detectives, participants are challenged to gather and share evidence to confront misconceptions about Earth’s land cover. Land cover is what is on Earth’s surface, such as trees, grass, pavement, and buildings.

The Challenge focuses on two misconceptions about land cover: 1) Land cover doesn’t change. 2) The land cover of an area doesn’t matter. Student teams are asked to select one of the misconceptions to investigate and make a claim to debunk or refute. Teams are then challenged to make observations and gather evidence to support their claim. Student teams write an engaging script and produce a 90 to 120-second video that addresses the misconception. In the video, teams conduct a demonstration/experiment or show how they used GLOBE protocols (GLOBE Observer app or GLOBE data sheets) to disprove the misconception. The videos encourage other students to engage in science by trying the demonstration and the GLOBE Observer app, with the necessary support and supervision. 

The NASA Spotlite Challenge: Land Detectives is currently accepting student production team submissions. All submissions must be received no later than Dec. 9, 2022, for the fall semester and March 24, 2023, for the spring semester.

NASA eClips™ Supports GLOBE Clouds Match to a Million Celebration

The NASA eClips education team from the National Institute of Aerospace’s Center for Integrated STEM Education (NIA-CISE) joined researchers, learners, and other educators from across the country to present a poster at the GLOBE Clouds Match to a Million Celebration on Sept. 13, 2022, at NASA’s Langley Research Center. The event celebrated GLOBE Clouds’ one million satellite matches to GLOBE Clouds citizen science data. 

NASA eClips has been a longtime partner with The GLOBE Program and, in particular GLOBE Clouds. The educators proudly shared multiple ways NASA eClips and GLOBE resources have leveraged and enriched each other with attendees. 

NASA eClips has partnered with the GLOBE Program, GLOBE Observer, and NASA’s Earth Science Education Collaborative (NESEC) to co-design and deliver integrative project-based and learner-centered challenges such as the NASA Spotlite Design Challenge: Cloud Detectives and NASA Spotlite Design Challenge: Land Detectives. The Cloud Detectives Spotlite Design Challenge, which runs continuously, asks learners to select one of two misconceptions about clouds. Teams investigate, make observations, and gather evidence to support their claim about clouds by collecting data using GLOBE Observer. Teams are then tasked with producing a short video that debunks the misconception. For disproving the misconception that “all clouds produce rain,” students at New York School for the Deaf created several videos, including Spotlite “The Rain Cloud.”

NASA eClips has also worked with The GLOBE Program to embed community-based integrative STEM experiences into curricula such as through training with the New York State Master Teachers Program, where 10 teachers were trained and 900 students were impacted, and Hampton City Schools, where 52 educators have been trained on GLOBE protocols and 1,945 learners were impacted. The GLOBE Program has provided a real-world context for learners to collect and analyze data. 

Many NASA eClips resources, such as the Our World: Designing a Cloud Cover Estimator Educator Guide, point to aligned GLOBE activities, helping to provide a variety of experiences educators can use in helping to build learner’s science practices and knowledge.

The NASE eClips education team consists of Dr. Sharon Bowers (Senior Education Specialist), Joan Harper-Neely (STEM Education Specialist) and Betsy McAllister (Educator in Residence).

UAS Atmospheric Measurements Supporting CST Learjet Acoustic Tests with GRC

A UAS, operated by personnel from Langley’s UASOO and National Institute of Aerospace’s Research Engineer, Jacob Revesz, conducted atmospheric characterization flights to support Acoustic Testing for the Commercial Supersonic Technology project.

In support of a Commercial Supersonic Technology project managed out of GRC, Langley personnel from the UASOO conducted 12 research flights with a UAS at Niagara Falls International Airport. The flights were used to characterize the weather conditions between an array of microphones on the ground and a Learjet operated by Calspan that flew over the array. Previous experiments utilized a weather balloon that had to be deployed and retracted each time to make the measurements. The UAS was easier to launch/recover, provided more consistent profiles and was logistically easier to operate. The UAS team has been invited to the Acoustics Technical Working Group meeting at GRC in Oct. to discuss the use of drones to measure weather information for flight tests.

NIA Research Scientist Presents at University of Wisconsin

Dr. Kathleen Miller, a Research Scientist at the National Institute of Aerospace (NIA), presented at the University of Wisconsin- Madison Department of Kinesiology Seminar Series. The title of the talk was “Ionizing Radiation and the Central Nervous System: Thinking about the Brain in Space.” The presentation was held on Sept. 23, 2022, in Madison, WI.

Abstract:
Space exploration requires the characterization and management or mitigation of a variety of human health risks. Exposure to space radiation is one of the main health concerns because it has the potential to increase the risk of cancer, cardiovascular disease, and both acute and late neurodegeneration. Space radiation-induced decrements to the vascular system may impact the risk for cerebrovascular disease and consequent dementia. These risks may be independent or synergistic with direct damage to central nervous system tissues. The purpose of this work is to review epidemiological and experimental data regarding the impact of low-to-moderate dose ionizing radiation on the central nervous system and the cerebrovascular system. A proposed framework outlines how space radiation-induced effects on the vasculature may increase risk for both cerebrovascular dysfunction and neural and cognitive adverse outcomes. The results of this work suggest that there are multiple processes by which ionizing radiation exposure may impact cerebrovascular function including increases in oxidative stress, neuroinflammation, endothelial cell dysfunction, arterial stiffening, atherosclerosis, and cerebral amyloid angiopathy. Cerebrovascular adverse outcomes may also promote neural and cognitive adverse outcomes. However, there are many gaps in both the human and preclinical evidence base regarding the long-term impact of ionizing radiation exposure on brain health due to heterogeneity in both exposures and outcomes. The unique composition of the space radiation environment makes the translation of the evidence base from terrestrial exposures to space exposures difficult. Additional investigation and understanding of the impact of low-to-moderate doses of ionizing radiation including high (H) atomic number (Z) and energy (E) (HZE) ions on the cerebrovascular system is needed. Furthermore, investigation of how decrements in vascular systems may contribute to development of neurodegenerative diseases in independent or synergistic pathways is important for protecting the long-term health of astronauts.

NIA Senior Research Scientist Presents at IFS Research Review Forum Tech Talk

Dr. Laura Titolo, Senior Research Scientist at the National Institute of Aerospace (NIA), presented “Taming numerical errors in safety-critical avionics applications” at the Intelligent Flight Systems (IFS) Research Review Forum Tech Talk held virtually at NASA Langley.

Abstract:
The development of software that depends on floating-point computations is particularly challenging due to the presence of round-off errors in computer arithmetic. These errors accumulate during numerical computations and may significantly affect the evaluation of both arithmetic and Boolean expressions.

Reasoning on floating-point computations is particularly important for safety-critical software where the divergence between the ideal real number computation and its floating-point counterpart can lead to catastrophic consequences.

This talk provides an overview of the different formal methods techniques that have been implemented and integrated to analyze numerical properties of NASA libraries for avionics applications such as geofencing, detect-and-avoid, and aircraft positioning.

Employed techniques include abstract interpretation, theorem proving, SMT solvers, and numerical methods, which have been successfully integrated to improve floating-point programs and to provide formal guarantees of their correctness.

Joan Harper-Neely (STEM Education Specialist), Dr. Sharon Bowers (Senior STEM Educator), and Betsy McAllister (Educator in Residence) from the National Institute of Aerospace’s Center for Integrative STEM Education (NIA-CISE) conducted a Virginia Department of Education training for 14 educators in grades PreK-5 on the use of the International Technology and Engineering Educators Association’s (ITEEA) Technology, Engineering, Environment, Mathematics, and Science (TEEMS) curriculum and aligned NASA eClips resources. The TEEMS modules are part of ITEEA’s Engineering by Design (EbD) curriculum.

During the training, educators were introduced to grade-appropriate TEEMS modules, worked through the modules’ authentic and project-based engineering challenges and NASA eClips activities for engaging and extending learning, and discussed best practices for implementing integrated STEM into formal and nonformal settings. 

Educators working with learners in grades 4th-5th were trained on June 28, 2022. Dr. Sharon Bowers led the educators in an icebreaker activity using the NASA eClips Real World: Balloon Aerodynamics Challenge 1 and 2 Educator Guide, where participants were challenged to create a neutrally buoyant balloon. As part of the 5th grade TEEMS module “Our Water, Our World,” participants simulated a drop of water and traveled through different parts of the water cycle. Joan Harper-Neely engaged the educators in learning about water conservation through the NASA eClips Our World: Designing a Shower Clock Educator Guide. As a part of the 4th grade TEEMS module “The Power of Solar,” educators built an “off the grid” playhouse and learned about the parts of our Sun through the NASA eClips Solar Images Guide Lites and the video, Our World “The Sun, A Real Star.”

Educators working with 2nd and 3rd grade learners were trained on June 29, 2022. In addition to completing the NASA eClips Real World: Balloon Aerodynamics Challenge 1 and 2 Educator Guide as an icebreaker, participants constructed a shake table and a structure resistant to high winds as part of the 3rd grade TEEMS module “Natural Hazards.” They learned about how NASA monitors climate change using the NASA eClips video, Our World “Monitoring the Earth’s Climate with CERES.” Educators worked collaboratively to engineer a seed spreader as part of the 2nd grade TEEMS module “From Nature to Me,” simulated pollinating a flower, and were introduced to the importance of pollinators through the NASA eClips video Our World “Honeybees.”

PreK-1st grade educator training occurred on June 30, 2022. Participants constructed a terrarium as a part of the PreK TEEMS module “Our Living World,” and learned about growth chambers used to grow plants in space through NASA eClips video Our World “Plants in Space.” Educators were introduced to the NASA eClips video Our World “Snowpits” as a way to engage or extend learning with the Kindergarten TEEMS module “A Home for All Seasons.”  Educators experienced multiple sound-related activities to familiarize themselves with the 1st grade TEEMS module “Can You Hear Me?” The NASA Spotlite video “Sound Waves and Media” was shared as a resource to help learners understand how a medium impacts sound travel.

Participants were excited to learn about the variety of NASA eClips resources that can be used to reinforce concepts and practices introduced with the ITEEA’s TEEMS curriculum.

NIA Associate Principal Engineer Presents to NASA Structural and Aeroacoustics Branches

Menachem Rafaelof, Associate Principal Engineer at the National Institute of Aerospace (NIA), presented development work on “Controlled High Fidelity Reproduction (CHFR) of UAM Vehicle Noise” to group members from the structural and aeroacoustics branches at NASA.

Abstract:

There is much expectation for proliferation of Urban Air Mobility (UAM) for passenger transport and delivery of goods.  One concern about the operation of these vehicles, either individually or as part of a fleet, is their noise emission and impact on the public. UAM vehicle noise could be annoying, distracting, or intrusive, potentially reducing the quality of sleep, increasing stress, or impacting speech audibility and other factors critical to the quality of life.

This effort conceived a new approach to allow reproduction of any UAM vehicle noise at a desire observer location for its assessment. A critical aspect of CHFR method is the virtual reproduction of high-fidelity noise matching the states of the vehicle and its noise sources throughout the flight.

NIA Associate Principal Engineer Collaborates in Completion of RVLT Milestone

Menachem Rafaelof, Associate Principal Engineer at the National Institute of Aerospace (NIA), has collaborated in the completion of a Revolutionary Vertical Lift Technology (RVLT) Gen 3 fleet noise assessment milestone. The objective was to develop a modeling approach to assess the acoustic impact of realistic UAM fleet operations using the FAA’s Aviation Environmental Design Tool’s (AEDT) helicopter mode and the recently developed Gen 3 noise-power-distance (NPD) database. There is broad interest in assessing the impact of noise on the public due to the flight of future urban air mobility (UAM) vehicles. During this effort, first, the noise by two concept vehicles, NASA’s Quadrotor and Lift Plus Cruise, under different operating conditions was predicted. Next, these vehicles were ‘flown’ along a realistic flight trajectory over a given terrain to assess their noise at different observer locations. To do so, this task explored the use of AEDT software for assessing noise by traditional commercial air traffic around airports. This task’s significance has been in identifying the advantages and limitations of AEDT to accurately replicate UAM vehicle noise at different observer locations.

NIA Senior Research Scientist Delivers Joint Talk at Virginia Commonwealth University

Dr. Alwyn Goodloe (NASA) and Dr. Ivan Perez, National Institute of Aerospace (NIA), visited Professor Carl Elks’ research group at Virginia Commonwealth University (VCU) in Richmond, VA. They gave an extended tutorial on the Copilot Runtime Verification Framework and associated Ogma tool both developed with System-wide Safety funding under TC4. In addition to members of Dr. Elks’ group, faculty members working in the area of robotics also were in attendance. Faculty and graduate students at the University of Virginia (UVa) were also in attendance via Zoom, as were several researchers at the National Institute of Technology (NIST). Professor Elks’ group has started using Copilot for working being conducted under a NASA research award (SWS TC2) and the tutorial introduced Copilot to those wanting to use it on other projects such as a large award from the Nuclear Regulatory Commission (NRC). During their visit, researchers from NASA, NIA and VCU discussed opportunities for joint research specifically focusing on robot controllers and on automatically generating hardware specifications for monitoring systems.

NIA Senior Research Scientist Publishes New Version of Runtime Monitoring Toolchain

Dr. Ivan Perez, Senior Research Scientist at the National Institute of Aerospace (NIA) and technical lead of the Copilot 3 and Ogma projects, published new releases of both systems (respectively, Copilot 3.9 and Ogma 1.0.3). Copilot 3 is a runtime verification framework created by NIA and Galois. Ogma, is a tool to transform structured natural language requirements into Copilot monitors and NASA Core Flight System applications. The new versions implement key features required to obtain NASA’s Class D software classification, which is expected to enable the monitors generated by the tools to be integrated in NASA Class C software. Both tools are currently being used in experimental drone flights carried out by the Safety-Critical Avionics Systems Branch (D320) of NASA Langley Research Center.

NIA Associate Principal Engineer Collaborates in Development of SAP Algorithm

Menachem Rafaelof, Assoc. Principal Engineer at the National Institute of Aerospace (NIA) and innovators at the NASA Langley Research Center (LaRC) have developed an algorithm for Statistical Audibility Prediction (SAP) of an arbitrary signal in the presence of noise. The SAP algorithm compares the loudness of signal and noise samples at matching time instances to assess audibility versus time. The continued development of this algorithm could allow engineers to suppress how we hear noise relative to sounds of interest. SAP can be implemented either as software or hardware. The algorithm has been tested using subject response data gathered in the Exterior Effects Room (EER) at NASA LaRC.

NIA Senior Research Engineer Gives Invited Talk at ICCMAE 2022

Dr. Xiaowen Wang, Senior Research Engineer at the National Institute of Aerospace (NIA), gave an invited talk at the Second International Conference on Computational Methods and Applications in Engineering (ICCMAE 2022), during the mini-symposium MA4: Instability, Transition and Turbulence in Fluids: Fundamentals to Applications. Dr. Wang’s talk, “Transition Control of Hypersonic Boundary Layers Using Ultrasonically Absorptive Porous Coatings,” was given on May 7, 2022. 

Abstract: 
The design of hypersonic vehicles is constrained by the considerable drag and heat transfer. These constraints are significantly enhanced as the boundary-layer transition happens. Strategies to maintain laminar boundary layers or delay transition can dramatically reduce drag and surface heating. For small amplitude disturbance, the transition of a boundary layer over a smooth surface consists of three stages: receptivity, modal growth of unstable waves, and breakdown to turbulence. According to the three-stage transition, modal growth of unstable boundary-layer waves is critical to transition control. In the past two decades, the stabilizing effect of ultrasonically absorptive porous coatings on hypersonic boundary layers has been demonstrated by theoretical analyses, experiments, and numerical simulations. In this work, a review of the existing literature on the topic is firstly reported. It is noticed that research on stabilization efficiency of porous coating is limited and almost all previous work considers either felt-metal porous coating or regular porous coating. Here, the stabilities of two hypersonic boundary layers are investigated with a combination of linear stability theory and numerical simulation, which shows the physics of transition control using porous coating. Three approaches are then proposed for the application of porous coating to achieve high stabilization efficiency.

NIA-CISE Engages Teachers and Students in Piloting Newly Revised NASA eClips Engineering Design Packets

Educators from the National Institute of Aerospace’s Center for Integrative STEM Education (NIA-CISE) recruited teachers from across the country to field test and provide feedback on the newly revised NASA eClips Engineering Design Packets (EDP). The “Elementary Engineering Design Packet” (students in grades 3-5) and “Secondary Engineering Design Packet” (students in grades 6-12) introduce students to a formal design process. The open-ended nature of the packets enables them to be applied to any design project and used with any curriculum, whether a formal or nonformal setting. In addition, packets are accompanied by an Engineering Design Packet Implementation Guide and a rubric that can assist teachers with implementation and evaluation.

On March 1, 2022, and April 18, 2022, the NIA-CISE Education Team hosted webinars where they introduced 10 educators to the Engineering Design Packets and the process that will be used to provide feedback on the packets. A recording of the presentation and supporting resources were provided to 21 educators who were unable to attend the webinar.

Pilot educators will customize the EDP with a design challenge of their choosing. Customized packets, along with a record of the time needed to become familiar with the Implementation Guide and time needed for students to work through the packet, will be shared with the NASA eClips’ external evaluator, Dr. Bradford Davey of Technology for Learning Consortium, Inc. In addition, pilot teachers will also complete a comprehensive survey of their experience and share anecdotal data from students. The valuable feedback provided by educators will be used to improve the packets so they will be ready for release for the 2022-2023 school year.

The Education Team from the National Institute of Aerospace’s Center for Integrative STEM Education (NIA-CISE) includes Dr. Sharon Bowers (Senior STEM Educator), Joan Harper-Neely (STEM Education Specialist), and Betsy McAllister (NIA Educator in Residence).

NASA eClips Participates in Yorktown Elementary Annual STEM Night

NASA eClips Educators participated in Yorktown Elementary School’s Annual STEM Night on April 19, 2022, engaging students and their families in actively building their understanding of the life cycle of a Sun-like star. 

Over 200 families moved through the stages in the life cycle of a Sun-like star. Participants swirled to simulate the gas and dust of a star-forming nebula, compressed themselves to represent a protostar, pretended to emit heat as a main sequence star, expanded themselves to represent a cooling red giant, expanded themselves further to illustrate a planetary nebula, before finally collapsing into a white dwarf. At each stage, students collected a colored bead that represented the stage. The beads were added to a chenille stem to create a life cycle bracelet of a Sun-like star.

Dr. Sharon Bowers (Senior STEM Educator) and Betsy McAllister (NIA Educator in Residence) at the National Institute of Aerospace’s Center for Integrative STEM Education (NIA-CISE) shared the varied and highly adaptable educational resources found on the NASA eClips website, including Our World “The Sun, A Real Star” and Launchpad “Life Cycle of a Star.”

NIA Senior Research Engineer Publishes in AIAA Journal 2022

Dr. Pedro Paredes Gonzalez, Senior Research Engineer at the National Institute of Aerospace (NIA), recently published “Linear Instabilities over Ogive-Cylinder Models at Mach 6” in AIAA Journal Volume 60. Co-authors include Anton Scholten (NCSU), J. Luke Hill (AFIT), Matthew Borg (AFRL), Joseph S. Jewell (Purdue), and Meelan Choudhari (NASA LaRC). The article was made publicly available 27 April 2022.

https://doi.org/10.2514/1.J061611

Abstract:

Computational investigations of a tangent ogive-cylinder geometry with varying forebodies at zero degrees angle of attack are presented. The model geometry and conditions are selected to match experiments conducted in the Air Force Research Laboratory (AFRL) Mach 6 Ludwieg Tube. Specifically, five forebodies of interest consisting of sharp and blunt ogives of 4 and 2 caliber and a hemispherical shape are studied at a freestream unit Reynolds number of 7.01×106m−17.01×106  m−1. Boundary-layer-edge properties and wall-normal profiles of velocity and temperature are compared across streamwise locations past the ogive-cylinder junction. Modal stability analysis is used to characterize the most amplified frequencies corresponding to Mack’s first and second modes and those are found to agree with experimental results for the sharp forebodies. The entropy layer induced by blunt forebodies envelopes the boundary layer and stabilizes modal disturbances. Nonmodal analysis revealed a broadband set of disturbances present for the blunter forebodies, in agreement with experimental observations. Flow perturbation contours of most amplified planar and oblique disturbances are shown to qualitatively match wind tunnel schlieren images, with a switch from rope-like to elongated structures, i.e., from high-frequency Mack’s second modes to low-frequency Mack’s first modes, as the forebody angle for the sharp tip is increased, and from boundary-layer to entropy-layer disturbances as the bluntness is increased.

Grand Challenge Reviews

Langley Professor Dr. Dimitri Mavris of the Georgia Tech Aerospace Systems Design Laboratory hosted a hybrid event last week in which graduate student teams presented the results of their two-semester Grand Challenge projects. Two of the projects were conducted under the auspices of the Langley Professor Program.

Analysis of Electrified Regional Operations (AERO)

Grand Challenge Abstract:

This Grand Challenge investigated how and where to operate an all-electric aircraft fleet subject to real-world constraints. To accomplish this goal, the team analyzed the main factors that realistically affect electric aircraft operations to determine their impact on the fleet utilization and overall operator profit.

While significant demand exists for regional operations, current commuter aircraft fleets are aging and are plagued with high operating and maintenance costs and high pollution rates. To revitalize this market segment and address current shortcomings, a paradigm shift in commuter aircraft is necessary, such as the use of an all-electric aircraft fleet, to satisfy demand in a given commuter region.

However, the operation of such an all-electric aircraft fleet comes with unique logistical and operational challenges, mainly due to range and turnaround time constraints. A review of the influential factors impacting such constraints identified three main fields: FAA reserve and alternate airport regulations, wind effects, and routing inefficiencies. Much of the variation and severity of these constraints depend on the weather conditions on a given day. Using the Northeast Corridor, the Hawaiian Islands, and the California Coast as case studies for all-electric fleet operation, the team developed an algorithm that compiles a distribution of energy required to fly any given route subject to randomly sampled historical weather conditions via a Monte Carlo simulation. The energy required distribution data is used to identify feasibility of current regional airline schedules, and if schedules are found infeasible for direct substitution of electric aircraft, then the team leverages an off-the-shelf scheduling optimizer to modify current schedules to produce feasible ones.

The team developed an interactive environment to allow a user to identify the effect of weather conditions and battery technology on individual routes and aircraft as well as fleet-level metrics such as utilization, average load factor, and overall airline profit. Further, these statistics can be filtered by location and season, allowing the user to compare the three case study locations’ disposition to electric regional air operations. The team developed a methodology for injecting real-world variability into electric aircraft operational studies.

Space Logistics and Mobility (SLAM)

Grand Challenge Abstract:

In the coming decades, the space industry will continue to rapidly grow and expand into cislunar space, as the barriers to entry are reduced, and nations continue to make efforts to expand beyond Earth.

Developments from the private sector have led to a dramatic reduction in launch costs, and an entire industry has been built around telecommunications and defense satellites. However, the lack of a space logistics network to support these assets drives up costs, as each individual mission is considered independently. For example, resupply missions will be extremely expensive if launch vehicles are required to propel supplies all the way to the surface of the moon, as upper stages are expendable. Additionally, a distributed series of supplies, fuel, and parts is needed for emergencies.

The Space Logistics and Mobility Grand Challenge focused on addressing the space infrastructure problem by developing a framework for evaluating alternative space infrastructure architectures. Building such an infrastructure is expected to be a major investment with high initial costs and major consequences for other space systems, motivating the need to design space infrastructure that will best meet multiple objectives, including initial cost, operations cost, and robustness. There is no existing precedent for such a space infrastructure network, which necessitates the development of a tool that can determine whether a given infrastructure concept reduces cost, and if so, in what quantity or location, where applicable.

2035 was selected as part of the study scoping, with a literature search being performed to compile concepts for space assets that will populate cislunar space during that time, including attributes such as

their consumption rates. Proposals for space logistics concepts were studied, and the three most viable concepts to construct and launch within the next 15 years were selected: supply depots, space tugs, and lunar in-situ resource utilization.

A Discrete Event Simulation (DES) was built around these infrastructure concepts. The DES was then coupled with a genetic algorithm to determine the solution to modified versions of traditional terrestrial supply chain problems: location-allocation, which focuses on facility quantity and location; location-inventory, which focuses on ordering policies, and location-routing, which focuses on optimal fleet sizes and routes.

NIA Research Fellow Publishes NASA Technical Memorandum

Dr. Ronald Krueger, Research Fellow at the National Institute of Aerospace (NIA), and Nelson V. De Carvalho (NASA LaRC), published “A Benchmark Example for Delamination Propagation Predictions Based on the Calibrated End-Loaded Split Specimen,” NASA-TM-20220002098. A benchmark example based on the Calibrated End-Loaded Split (C-ELS) specimen was developed and used to assess the performance of recently developed delamination propagation capabilities in the Abaqus/Standard finite element code. The C-ELS specimen has the advantage of a longer region of stable delamination propagation compared to the existing mode II benchmark case. The new benchmark example may therefore provide a better assessment tool by enabling more stable crack growth in regions further away from the boundary conditions or load application. Detailed results from three-dimensional analyses with aligned and misaligned meshes and two levels of mesh refinement are provided for several permutations of numerical input parameters. In general, good agreement can be achieved between the results obtained from the quasi-static propagation analysis and the benchmark analysis. However, particular non-default settings are found to be most reliable, accurate, and numerically efficient. Use of the benchmark case to assess the continuous improvements in one finite element code illustrates the value of establishing benchmark solutions.

NASA eClips Education Team Shares Resources in 3-D Thursday Webinar for Rural Educators

The NASA eClips Education Team presented at the 3-D Thursdays NASA Series for K-12 Rural Educators webinar held on March 3, 2022, to 21 educators from across the nation. The webinar series is hosted by Rachel Arens, Associate Researcher at NAU PLANETS (Northern Arizona University’s Planetary Learning that Advances the Nexus of Engineering, Technology, and Science) and Michael Guarraia (Albert Einstein Distinguished Fellow at NASA’s Science Mission Directorate). The monthly Three-Dimensional Thursdays webinar series aims to enhance rural educators’ access to NASA resources, networking, and professional development. While focused on rural educators, the webinar series is open to all educators.

The NASA eClips Education Team introduced participants to the suite of resources that support standards-based instruction by increasing STEM literacy in both formal and nonformal settings. Participants explored the resources in greater depth through a series of scavenger hunts in the NASA eClips website. They identified the short length of NASA eClips videos and the ability to download them easily and on-demand as reasons they are ideal resources for rural areas where bandwidth may be a limiting factor.

NASA eClips videos consist of Our World, Real World, Launchpad and Ask SME: Close-up with a NASA Subject Matter Expert videos, as well as student-produced Spotlite videos. The audience for NASA Our World videos are created for students in grades 3-5 to help them understand the difference between science (the natural world) and engineering (the designed world). Real World segments, designed for students in grades 6-8, connect classroom mathematics to 21st-century careers and innovations. NASA Launchpad videos focus on NASA innovations and technologies that will take us into the future. “Ask SME: Close-up with a NASA Subject Matter Expert (SME)” videos gives the audience a chance to “meet” NASA SMEs and learn about their personal interests and career journeys, expanding student awareness of STEM careers. Participants identified the use of diverse hosts and SMEs as reasons they will use the eClips to introduce and engage audiences, build conceptual understanding, and extend learning with audiences.

Participants also took a deeper dive to learn more about NASA eClips Guides. They expressed that both the Educator Guides, which provide ways to use eClips videos effectively, and the shorter Guide Lites will excite and engage learners in both formal and nonformal settings. Guide Lites focus on a single activity from an Educator Guide. Participants identified that VALUE (Varied & Accessible Learning Resources for Universal Engagement) Bundles give students choices in how they learn about a topic. The carefully curated NASA eClips and partner resources within a VALUE Bundle provide a cohesive and intriguing set of materials that meets the needs of a wide variety of learners. Participants believed the newly redesigned Engineering Design Packets will be a valuable tool their learners could use with any design challenge.

The audience was also introduced to the NASA Spotlite Design Challenge, in which student teams write an engaging script and produce a 90-120 second Spotlite video that addresses a science misconception. The detailed supporting materials and intuitive nature of the challenge were identified as reasons participants expressed their plan to use the resource with learners in the future.

The NASA eClips Education Team from the National Institute of Aerospace’s Center for Integrative STEM Education (NIA-CISE) consists of Dr. Sharon Bowers (Senior STEM Educator), Joan Harper-Neely (STEM Education Specialist), and Betsy McAllister (Educator in Residence).

CHROME Club Invites NASA eClips to Engage Middle School Students in STEM Activity

Alexis Tharpe, a middle school teacher from Hampton, VA, invited the NASA eClips team to engage 25 girls in a STEM activity during a CHROME Club meeting on Feb. 24, 2022. Cooperating Hampton Roads Organizations for Minorities in Engineering (CHROME) provides teachers of K-12 students opportunities to increase opportunities and awareness in science, technology, engineering, and math (STEM). Joan Harper-Neely, STEM Education Specialist from the National Institute of Aerospace ‘s Center for Integrative STEM Education (NIA-CISE), introduced the girls to an astrophysicist by sharing Ask SME: Close-up with a NASA Subject Matter Expert “Dr. Nicholeen Viall – Astrophysicist.” Several girls said they could relate to Dr. Nicholeen Viall because they also like dancing and are curious about the sun, stars, or space. Working in teams, CHROME club members created life cycles of star bracelets to learn how sun-like stars and massive stars from Seeing Starlight with the James Webb Space Telescope. The student-produced video, NASA Spotlite “Stars,” was shared to inspire the girls to use their voices to create science content for others and encourage peers to do their own science investigations.

NIA-CISE Presents NASA eClips at the 2022 Space Exploration Educators Conference

Dr. Sharon Bowers, Senior STEM Educator at the National Institute of Aerospace’s Center for Integrative STEM Education (NIA-CISE), presented two sessions at the 2022 Space Exploration Educators Conference (SEEC) in Houston, Texas.

On Thursday, Feb. 3, 2022, Dr. Bowers joined Dr. Aleida Higginson (Research Astrophysicist), Dr. Michael Kirk (Research Scientist), and Carolyn Ng (Education Specialist) from NASA’s Goddard Space Flight Center’s Heliophysics Division, and Dr. “Trae” Winter (Solar Astrophysicist) and MaryKay Severino (Education Director) from the Advanced Research Inclusion and STEAM Accessibility (ARISA) Lab to present NASA Science: Getting Ready for the Next Solar Eclipse.

The purpose of the session was to engage the 29 face-to-face and 35 virtual participants in exploring the Sun-Earth connection through hands-on activities, real-time data, and “live” interactions. The session prepared participants to maximize the excitement and learning for the upcoming solar eclipses visible in the United States (annular solar eclipse on October 14, 2023, and total solar eclipse on April 8, 2024). Participants introduced themselves and interacted with each other through Padlet and learned about NASA resources through a Solar Eclipse Scavenger Hunt. Resources were shared with participants through a Solar Eclipse LiveBinder. Participants created solar images (NASA eClips’s Interactive Lesson: Solar Images Guide Lite) and used filters of various colors to test how wavelength affects images being viewed (NASA’s Our World: Rose Colored Glasses – A New Camera for Hubble Educator Guide and NASA eClips’s Rose Colored Glasses Guide Lite).

The presentation was one of three SEEC proposals developed by NASA Science Activation (SciAct) teams. SciAct, is a network of teams across the nation that connects NASA science experts, real content, and experiences to do science in ways that activate minds and promote deeper understanding of our world and beyond.

On Friday, Feb. 4, 2022, Dr. Bowers joined NASA eClips Technical Advisory Board Member and Accessibility and Inclusion Specialist at Space Center Houston, Stephanie McMahon, to present Science and Engineering – Similar, but Different: Tools and Resources to Grow Young Scientists and Engineers.

Fifty-two participants joined Bowers and McMahon in a hands-on exploration of the similarities and differences between inquiry and the Engineering Design Process (EDP). To frame science inquiry, participants were introduced to the 2021 NASA eClips production Real World “The Nature of Science.” Participants explored the engineering design process using the SCAMPER strategy (substitute, combine, adapt, magnify/minify, put to another use, eliminate, reverse/rearrange) to improve a shower clock design (adapted from NASA’s Our World: Designing a Shower Clock Educator Guide).

The session expanded participant knowledge of ways to engage students to think and work like scientists and engineers. Participants were introduced to a wide variety of NASA Citizen Science and Engineering Design resources through a LiveBinder.

Dr. Bowers also supported the SciAct presentations NASA Science: Hands-On Exploration of Our Solar System on Feb. 3, 2022, and NASA Science: Exploring NASA Science Missions on Feb. 4, 2022.

NIA Associate Principal Engineer Files Patent for Statistical Audibility Prediction (SAP)

Menachem Rafaelof, Associate Principal Engineer at the National Institute of Aerospace (NIA), has filed a patent for “A method for Statistical Audibility Prediction (SAP) of an arbitrary sound in presence of another sound”. Accurate prediction of the audibility of an arbitrary signal in presence of noise is a difficult task. This difficulty stems from the need to handle infinite types and combinations of signals and noise with unique time and frequency characteristics; at the same time, one must account for the uncertainty in the prediction process that reflects the complex function of the human auditory system. One major category is the development of all types of quiet machines for air and land transportation, machines slated for operation in hospitals and at home, HVAC systems, industrial machines, etc. In other applications, such capability could assure that critical devices (e.g., alarms or telephones) or speech would be audible in the presence of different ambient noise. Statistical Audibility Prediction (SAP) method relies on the specific loudness or loudness perceived through the individual auditory filters for accurate statistical estimation of audibility vs. time. Time-frequency prediction of audibility may provide valuable information about the root cause(s) for audibility essential for design and operation of sources of noise.

NIA-CISE STEM Education Specialist and VP of Education Programs for IGES Present the Cloud Detectives Spotlite Design Challenge in GLOBE/ESS Water Cooler Webinar

Joan Harper-Neely, STEM Education Specialist from the National Institute of Aerospace’s Center for Integrative STEM Education (NIA-CISE) and Theresa Schwerin, Vice President of Education Programs at the Institute for Global Environmental Strategies (IGES), presented the NASA Spotlite Challenge: Cloud Detectives to 16 participants at the GLOBE/Earth Systems Science (ESS) Collaborative Water Cooler webinar on Jan. 27, 2022.

NASA eClips has partnered with NASA’s Earth Science Education Collaborative (NESEC), The GLOBE Program, and GLOBE Observer to co-develop and promote the NASA Spotlite Challenge: Cloud Detectives.

Harper-Neely guided participants through each phase of the Challenge, which focuses on one of two misconceptions about clouds: 1) All clouds produce rain; and 2) Clouds are made of gas. Student teams are asked to select one of the cloud misconceptions to investigate and make a claim to refute the misconception.  Teams are then challenged to make observations and gather evidence to support their claim. Student teams write an engaging script and produce a 90-120 second video that addresses the misconception. In the video, teams conduct a demonstration/experiment or show how they used GLOBE cloud protocols (GLOBE Observer app or GLOBE data sheets) to disprove the misconception.  The videos encourage other students to engage in science by trying the demonstration and the GLOBE Observer app, with the necessary support and supervision. 

Theresa Schwerin elicited feedback from participants on how they could use the Cloud Detective challenge in their current role, as well as how the challenge could be used to further expand community engagement in GLOBE.

The NASA Spotlite Challenge: Cloud Detectives is currently accepting student teams. All submissions must be received no later than March 25, 2022.

CERTAIN Smart Center Completes Initial Perimeter Surveillance Flights

The CERTAIN Smart Center (SC) team, including Jacob Revesz, Research Engineer at the National Institute of Aerospace (NIA), completed the project milestone of demonstrating an initial proof-of-concept of the capability to use an sUAS to surveil a portion of LaRC’s perimeter fence line. The Dec. 13 demo attendees included personnel from OD, ARD, COD, RD, ED, and RSD.

The Dec. 2021 milestone of demonstrating an initial proof-of-concept of LaRC’s capability to use an sUAS to perform perimeter surveillance was met on Dec. 13 by performing a live perimeter surveillance demonstration. Using a payload-equipped Alta 8 small Uninhabited Aerial System (sUAS) vehicle, live video from the vehicle was relayed to the Mission Operations & Autonomous Integration Center (MOSAIC) in B1268A for observation by an officer from Langley’s Office of Protective Services (OPS). The OPS officer, located in the MOSAIC, could request pausing of the flight plan through voice communications to the ground control station operator, who was located on the CERTAIN range, and could request camera gimbal/zoom control to inspect any anomalies to determine if the dispatch of ground units was necessary. Camera control utilized Botlink 4G LTE communications allowing the camera operator to be co-located with the OPS officer in the MOSAIC. The demonstration featured two simulated fence line anomalies, both of which were successfully identified by the OPS officer within the MOSAIC.

The successful demonstration represents six months of effort to develop a perimeter surveillance use case with OPS, obtain a suitable sUAS, stand up the MOSAIC, integrate required hardware onto the sUAS, develop camera/gimbal control software, perform all required reviews, conduct ground, caged, and initial free flight testing, and perform flight envelope expansion. The demonstration paves the way for expanding operational sUAS capabilities on the center.
