Given that vehicle, habitat, and workspace designs must accommodate variations in human physical characteristics and capabilities, and given that the duration of crew habitation in these space-based environments will be far greater than missions of the past, there is a risk of acute and chronic ergonomic-related disorders, resulting in flight and ground crew errors and inefficiencies, failed mission and program objectives, and an increase in the potential for crew injuries.
To promote safe and efficient human performance during space missions, it is important to consider in the design process not only the effects of microgravity, acceleration, vibration, and other environmental conditions, but also human capabilities and limitations with respect to the use of equipment, and how those may change as crewmembers become deconditioned on long-duration journeys. When these are not considered, there is a risk of incompatible vehicle/habitat design. Examples of short-term effects due to this risk include overexertion, difficulty in reading a checklist due to spacecraft vibrations or inadequate lighting, high temperatures in a module due to inefficient co-location of habitability related hardware and excessive activities, difficulty donning a suit due to inadequate habitable volume, and difficulties communicating with fellow crewmembers due to high levels of noise in the cabin. Performance-related inefficiencies may include unnecessary translations between workstations to complete tasks, and increased task completion time due to difficulty in accessing equipment or lack of restraints for performing tasks requiring stability. Examples of long-term effects include ergonomic-related/ cumulative trauma disorders that are a result of repetitive motions, sustained maintenance of awkward postures, insufficient workspace clearances resulting in frequent over-exertions, suit hardware requiring sustained performance at maximal levels, and permanent hearing loss. Interacting with a vehicle/habitat environment that does not accommodate the crew along all anthropometric ranges, and does not consider human capabilities and limitations, and how these may change during long-duration spaceflight could lead to injuries, crew frustration, and/or mission failure.
The risk of incompatible vehicle/habitat design is broad and represented by eight contributing factors: 1) Anthropometric and biomechanical limitations, 2) Motor skill/coordination or timing, 3) Space and lunar visual environments, 4) Vibration and g-forces, 5) Noise interference, 6) Seating, restraints and equipment, 7)Visibility/window design & placement, and 8) Vehicle/habitat volume/layout. Related factors and risks are linked as appropriate.
One of the most critical enablers of human presence in space has been ensuring that there are human systems standards in place that will provide for crew health as well as standards for habitability, environmental, and human factors. The Space Flight Human System Standards (SFHSS) and the companion Human Integration Design Handbook (HIDH) require that each human spaceflight program derive program-specific, verifiable requirements to comply with the standards, and require that each human spaceflight program establish a human factors process involving health and human factors experts. This is to ensure that there will be identification of any standards in the SFHSS that are not applicable (or altered) and the rationale for non-applicability; that all program-level health and human factors requirements are based on the HIDH, cited empirical evidence, or known best practices; and that end-items are in compliance with SFHSS, and agency and program-level requirements and specifications.
The activities cited reflect the need to work toward the mitigation of identified Human Factors risks by continuing to inform the standards, by engagement in the development of the requirements that will implement the standards based upon the resulting products, as well as providing content to the HIDH that will serve as the implementation guide. In addition, products resulting from these activities may provide valuable information to spaceflight programs that can inform the requests for trade studies.
To ensure operational relevance of the deliverables from the tasks, all tasks leaders will identify stakeholders who will work with them in framing the questions and approach.The stakeholders will participate by identifying specific HAB issues requiring research or technology development, by reviewing progress, and by suggesting operational evaluations. Depending on the specific tasks, stakeholders may include engineers or operations personnel familiar with HAB issues in their domain. The approach to mitigating this risk is to develop an understanding of the factors that contribute to this risk, identify gaps in our knowledge about these factors or technology to address these factors, and prioritize these gaps based on various criteria systematically applied. Then the highest priority gaps are addressed through directed or solicited research, depending on the time frame, the complexity and specificity of the gap, and whether access to NASA proprietary data or operational settings is required. Where there is a disconnection between critical gaps requiring addressing and a lack of funding, efforts are made to re-examine programmatic priorities to ensure those of highest concern are being investigated.
The Space Human Factors and Habitability Element also solicits input from its Discipline Integrated Product Team (DIPT). This team aids in the periodic updating of our evidence base (including research, anecdotal findings, and operational information), as well as in the honing and vetting of existing knowledge and research gaps.
After all concerns are mapped to gaps, the gaps are prioritized according to a number of criteria. For example, when we identify needs within the NASA-STD-3001, VOL. II, ‘NASA Space Flight Human System Standard Volume 2: Human Factors, Habitability, and Environmental Health’, these are assigned a very high priority. Ratings are solicited from management representatives of the offices from which gaps were identified.
After prioritization, the gaps that can be addressed within the budget are initiated through directed research or solicited through research announcements. Directed research is chosen for time-critical results. Solicitations are used for gaps that are longer term and that can benefit from wider participation.
At the conclusion of each task, the final report is reviewed and the relevant evidence report is modified or updated to indicate how the results of the research or technology activity address the gaps and contribute to quantifying or mitigating risk or risks. If applicable, the results will also be incorporated into NASA-STD-3001, VOL. II and the HIDH.

Status:
Open
Initial State:
Long-duration missions may require unique and possibly challenging considerations for vehicle/habitat environmental factors (e.g., vehicle layout design, net habitable volume, lighting and noise). We do not know the effect of environmental factors on crew performance within a vehicle/habitat during long-duration missions.
Interim Steps:
- Review current state of knowledge gathered from HAB-04 to develop a candidate list of vehicle/habitat environmental factors that may impact human performance (e.g., acoustics, vibration, lighting).
- Identify areas for solicitation and directed research related to the quantification/characterization of the impact of environmental factors on minimum acceptable NHV and vehicle/habitat layout design.
- Release and implement solicitations and/or initiate directed studies to implement research for identified needs.
- Assess the relevance and maturity of research results from the solicitations, identifying key findings critical for characterizing vehicle/habitat environmental factors that may impact human performance.
- Integrate results to quantify effect sizes and thresholds for vehicle/habitat environmental factors on human performance during long-duration missions.
- Complete Habitability Working Group review of proposed list of key thresholds and ranges related to environment impacts.
Approach:
- Perform data mining and data collection/analysis of spaceflight and analog environment data relevant to vehicle/habitat environmental factors for tasks/scenarios during long-duration missions.
- Solicit research targeted at the effects of vehicle/habitat environmental factors on tasks/scenarios.

Aims:
Methods and tools (i.e., iSHORT, iQ&A) were developed and used to collect near real-time human factors and habitability data during spaceflight missions. Having a means to collect near real-time data reduces reliance on human memory and has the ability to capture small issues that may have a cumulative effect. These issues may result in crew frustration and inefficiencies. This study had two aims.
Aim 1: Using near-time reporting, characterize human factors and habitability aboard the ISS, which includes self-reported negative, neutral, and positive observations and assessments.
Aim 2: Preliminarily characterize crew utilization and perceptions of specific ISS habitat components/locations.
These efforts resulted in recommendations for future vehicle design, as well as proposed changes to NASA standards.

Description:
The deliverable for this task was a report: ISS Habitability Assessment. This report describes the research performed under the Habitability Assessment of International Space Station (ISS Habitability) Human Factors and Behavioral Performance (HFBP) Directed Research Project. This study addressed the Risk of an Incompatible Vehicle/Habitat Design by collecting and analyzing data about human factors and habitability on board the ISS and making recommendations for future vehicle and mission designers. The study utilized two custom iPad applications, Space Habitability Observation Reporting Tool (iSHORT) and iQuestion and Answer (iQ&A), which allowed participants to make open-ended observations about their living and working environment and respond to questionnaires. Six ISS crewmembers participated in the study, one 1-year crewmember and five standard-duration crewmembers. Data was collected throughout the participants’ missions. Participants were asked to capture observations about their environment about once every two weeks; to capture a walk-through video of an area of ISS about once per month; to narrate a task about once per month; to complete a human factors and habitability questionnaire three times per mission; and to participate in a principle investigator (PI) conference with the investigator team following each questionnaire. Content analysis was used to categorize the data and draw general conclusions in order to make recommendations for future vehicle and habitat design.

Procurement Mechanism(s):

Aims:
The Space Launch System (SLS) vibration profile is different than Ares profiles tested previously. We do not know the impact of lateral vibration on ability to read displays.
- Determine observer reading task performance in laboratory experiment (i.e., 1-Gx bias) for lateral vibration bracketing the amplitudes of concern (~ 0.25 gzero-peak) over frequency range of interest (10-13 Hz).
This task addressed HAB-03 interim step bullet 5. Results from this study were provided to SLS and Orion stakeholders and were incorporated into the program’s revised thrust oscillation (TO) requirements and/or technical performance measures. The study informed the development of a new requirement by SLS-Multi-Purpose Crew Vehicle (MPCV) limiting 10-13 Hz TO-driven lateral vibration to ≤ 0.7 g (peak) and ≤ 0.5 g-rms (5-s running window).
The results are also available for inclusion in Human Integration Design Handbook (HIDH) as new information on visual tolerance to 12-Hz lateral vibration. The study also identified needs for future work to be carried out under the appropriate HRP Evidence Report vibration risk statements.
This will close the gap on the effects of 12-Hz lateral vibration on visual performance. A new round of human-in-the-loop testing could become necessary if projected lateral vibration levels were to increase during future vehicle design.
Integration/Unique Aspects:
Orion, Space Launch Systems (SLS) requested this information. Health and Medical Technical Authority (HMTA) and the Astronaut Office were stakeholders.

Procurement Mechanism(s):

Aims:
Acoustic modeling can be used to identify key noise sources, determine/analyze sub-allocated requirements, keep track of the accumulation of minor noise sources, and to predict vehicle noise levels at various stages in the development, first with estimates of noise sources, later with experimental data. Bench testing of isolated systems alone is not sufficient as the installation effects are often not known.
Acoustic modeling will be used:
- Determined installation effects, reverberation (room geometry) effects, and used to identify propagation paths and possible noise controls, as well as develop an understanding of the resulting acoustic levels in the composite environment.
- Assisted with the development and implementation of spaceflight acoustic materials and predicted their effectiveness including sound containment, absorption and vibration isolation.
The Acoustics Modeling Task completed all if its aims, contributing to closure of the HAB acoustic model gap as written. Acoustic modeling capability to predict resultant levels and spacecraft reverberation characteristics from bench testing of isolated systems, acoustic material sample data, and vehicle geometry has been validated for air-borne noise propagation. Results from this research were provided to the Constellation Program including Crew Exploration Vehicle (CEV) and Altair Lunar Lander Projects so that a more informed oversight of the vehicle development could be implemented with insertion of critical information such as validation of noise allocations for sub-systems, estimation of vehicle noise levels, and identification of potential acoustic problem areas and possible solutions. The capability developed under this project has been used to validate acoustic models and noise control approaches for application to the Orion Crew Exploration Vehicle and Altair Lunar Lander. In addition, applications of the acoustics modeling to interior space design were provided for addition to the Human Interface Design Handbook (HIDH) in the form of recommendations and guidelines. Structural damping measurement, structure-borne noise modeling, and human body acoustic modeling are still in need of development.

Aims:
The overarching goal of this proposal is to characterize the three less well-understood NIMH RDoC domains related to positive valence, negative valence, and social processes as they relate to the performance, adaptation, and resilience of individuals living and working in ICC/ICE environments. The investigator team will identify predictive indicators and biomarkers for resilience and adaptation in individuals and teams, to aid in astronaut selection and individualized countermeasure development with the goal to maintain and optimize performance capability and behavioral health during long-duration exploration missions (LDEM).
The specific aims of this study are:
Aim 1: Identify and quantify individual differences in adaptation and resilience, key threats to and promoters of mission relevant behavioral health and performance. The investigator team will use components of the RDoC framework to look across individual risk factors in order to identify and validate molecular, circuitry and physiological measures that can be used for monitoring and selection of individuals who are highly resilient to the key behavioral health and performance threats during autonomous, long duration and/or long distance exploration missions.
Aim 1a. Perform a comprehensive literature review of the RDoC framework to identify the units of analysis (e.g., cells, etc.) of the individual risk factors most related to LDEMs and positive valence, negative valence and social processes domains.
Aim 1b. Identify how the risk factors within those three RDoC domains relate to performance outcomes, resiliency, and adaptation in LDEMs.
Aim 2: Identify neural circuits and molecular/cellular mechanisms underlying adaptation and resilience in a rodent model using cross-species equivalency.
Aim 3: Encompasses the biological basis of social support to assess individual sociability and the neurobehavioral contributions to resiliency and/or adaptability of engaging positively in social interactions, tolerance, and awareness (e.g., affiliation, attachment).
Aim 4: Identify how meaningful work mediates the relationship between risk factors, the valence and social process domains, and operational outcomes, as well as direct effects of meaningful work on performance. The intent is to identify a sensitive, reliable, valid, and feasible set of measures for measuring and monitoring meaningfulness of work in spaceflight.
Aim 5: Encompasses the need to identify how positive and negative valence systems impact on psychological well-being and performance when confronted with the adverse conditions found in prolonged space flight. We will identify biomarkers and psychological report measures associated with the effects of well-being on performance and determine their contribution to the positive/negative valence systems involved in individual adaptation and resilience.

Aims:
The primary objective of this project was to provide information pertaining to changes in seated height due to spinal elongation in a microgravity environment. Spinal elongation has been observed to occur in crew-members during space flight; however, it has only previously been recorded in the standing position with a limited number of subjects. Seated height data in microgravity is considered necessary to identify correctly the seated height projections of the crew in the Orion configuration or future confined seated postures.
The experiment aimed to:
- Collect seated height data for subjects exposed to microgravity environments
- Provide information relating to seated height rate of change over time
- Deliver new information regarding the elongation of the spine forward into the design of Constellation.
The Spinal Elongation Task completed all its aims, contributing to closure of the HAB gap on microgravity effects on spinal elongation. Study findings were provided to the Constellation Program’s Crew Exploration Vehicle (CEV) to aid with the seat design and evaluations, and account for in-space growth adjustments to accommodate crew in terms of clearance, fit, access/reach and seat ingress/egress. Results from this study were also delivered and can be added to the Human Integration Design Handbook (HIDH) in the form of recommendations and guidelines. This inflight activity provided microgravity data on crew anthropometry that could also be used in suit sizing adjustments in space. Further data will need to be collected to determine effect of the personal factors on anthropometric measurements and its trend over time.

Initial State:
Currently we do not know the acceptable threshold or ranges for habitable volume and the preferred internal layout for a vehicle/habitat for a given set of mission attributes. Long-duration missions will have increased crew autonomy and with no resupply. There are a number of guidelines and measurement techniques for designing and assessing vehicles/habitats that need to be developed and validated for predetermined mission attributes.
Interim Steps:

Status:
Open
Initial State:
Human Factors (HF) does not currently have a complete, quantitative risk definition [including established critical thresholds or ranges for various mission attributes (e.g., duration, resupply)] for incompatible vehicle/habitat design, nor is there a description of the relative contribution of the contributing factors and how the human accommodation in space vehicle/habitat design compares to the human accommodation in terrestrial vehicle/habitat design. HF is concerned with the physical aspects of this risk; whereas, BMed-Sleep and Team are concerned with the psychological aspects of this risk.
Interim Steps:
Establish a Habitability Working Group composed of representatives from relevant HRP Elements (e.g., ExMC, HHC), Habitability Subject Matter Experts, and stakeholders. The Habitability Working Group will provide a forum for activities such as assessing quality and maturity of solicitation products, assessing potential collaboration opportunities with other HRP Elements and/or external research groups, and vetting guidelines.
- Review available data sources (e.g., Human Performance Data Repository, Design Reference Missions, Orion and ISS lessons learned, NHV workshop reports, other relevant HRP Element gaps and research areas, ISS Crew Comments Database) to document the current state of the standards, guidelines, ground rules and processes, and identify information needed in HF HAB gap closure plans (HAB-01, -02 and -05).
- With input from the Habitability Working Group, identify and refine critical mission attributes (e.g., critical task list, number of crew, length of mission, spacecraft typology, gravity, comm bandwidth) that will be necessary for determining, assessing and monitoring NHV and vehicle/habitat layout design in potential future human spaceflights.
- Document the current guidelines, ground rules, and processes that define the state of knowledge for determining, assessing and monitoring NHV and vehicle/habitat layout design.
- Obtain concurrence/approval from the appropriate review board(s).
Approach:
- Utilize interviews, workshops and Technical Interchange Meetings (TIMs) as appropriate to gather subject matter expert and stakeholder knowledge, arrive at consensus on important issues, and vet products such as mission attributes and “current-state” guidelines.
- Define mission attributes used for assumptions for initial estimates of volume risks based on data mining of existing and previous program products regarding vehicle/habitat layout design and NHV.
- Use literature reviews and existing models to refine critical inputs for guidelines such as critical task volumes.
Define and document the current state of guidelines, ground rules, and processes, and a refined set of critical mission attributes relevant for determining, assessing and monitoring Net Habitable Volume (NHV) and vehicle/habitat layout design. This information will refine the definition of the Risk of Incompatible Vehicle/Habitat Design and define acceptable levels of risk due to inadequate NHV and vehicle/habitat layout design.

Status:

Initial State:
The Human Factors (HF) Standing Review Panel (SRP) recommended increased use of computational models by NASA. However, there is currently no NASA standard for use of human-system models in engineering and requirements verification, or in human rating. Current NASA designers occasionally resort to creating their own computer graphics models, with a resulting unvalidated, potentially inaccurate model due to the lack of flight data. In addition, data collection technologies, including both obtrusive and unobtrusive, need to be developed to collect flight data that can be used to develop validated computational models and aid in the design and layout of safe and efficient vehicle/habitat for long-duration missions.
Interim Steps:
- Review products developed as part of HAB-04 for a candidate list of tasks/scenarios that need technologies, tools, and methods for the design and assessment of the vehicle/habitat for long-duration missions.
- Develop a list of technologies, tools, and method characteristics with specifications for habitability assessment, data collection, and analysis for identified tasks/scenarios (e.g., need to measure without complex tools, unobtrusive data collection, level of precision needed in measurements).
- Select from list of technologies, tools, and methods for the identified tasks/scenarios to be developed through solicitation and directed research.
- Release and implement solicitations and/or initiate directed studies to implement research for identified needs.
- Validate the tools/methods, integrating research results to provide mission characteristic-dependent vehicle/habitat designs and layouts. This process includes: finalizing impacting variables, refining inputs to the tool/method, and defining the metrics.
- Work with the Habitability Working Group to assess the quality and maturity of technologies, tools, and methods in terms of their usefulness for the characterization of acceptable level of risk related to design and assessment of vehicles/habitats volume/layout.
- Obtain approval from Habitability Working Group for the suite of tools, metrics, methods and supplementary materials that will assist in quantifying NHV and vehicle/habitat layout design based on mission attributes.
Approach:
- Utilize Small Business Innovative Research (SBIRs), NASA Research Announcements (NRAs), and Directed Research Projects to target specific data collection technologies and modeling tool goals such as reporting of human factors issues, automated video analysis, modeling of required NHV and vehicle/habitat layout design, and automated habitability data collection.
- Validate and refine tools and methods produced through solicited research and use of in-flight or analog data.
Validated data collection technologies, models, modeling methods and new/updated standards, guidelines and processes to design and assess vehicle/habitat designs; documented in NASA standards and guidelines (e.g., NASA-STD-3001 and HIDH).

Aims:
Future space vehicles will be challenged in the area of net habitable volume (NHV) due to launch mass limitations. Yet, we know that performance, work efficiency and crewmember satisfaction depend on adequate NHV and internal layout. Computational modeling and simulation both offer effective means to design vehicle/habitat and optimize NHV. However, developing and validating models requires systematically assessing architectural layout and three dimensional (3-D) space utilization. Using novel tracking and detection methods (e.g., such as Radio Frequency Identification (RFID) tags, sensors or other technologies) should make it possible to unobtrusively and non-invasively capture onboard space utilization data. These types of tools can provide an effective means to collect crew activity data needed to support future computational models.
The objective of this project is to develop and validate an automated data collection system that delivers data useful in the analysis of space utilization and vehicle habitability pertaining to crew activities on the ISS as well as potential long duration space missions. The investigation will utilize two independent technologies, 3D RFID-Real Time Location System (RTLS) and Microsoft Kinect 3D volumetric and anatomical scanning tools, integrating them into a single solution. The project will advance the integrated system through validation using the Human Research Program (HRP) Human Exploration Research Analog (HERA) platform.
*HERA validation will not require usage during scheduled missions.*
- Develop and demonstrate one or more practical and affordable methods of unobtrusively collecting habitability metrics of interest.
- Validate tools and methods.
- Create or update NASA standards/guidelines and processes.
Integration: This task may also address several other risks of potential HRP customers such as HHC and ExMC.

Aims:
During Phase I, Vecna demonstrated the feasibility of Automatic Video-based Motion Analysis (AVIMA), a video-based human motion analysis and visualization tool that automatically processes video footage of humans without the use of specialized markers. AVIMA features key innovations such as a video analytics module, a human motion analysis module which automatically estimates and tracks the 3D human body pose from video footage across a variety of operating scenarios, and a video analytics module which automatically interprets the subjects’ movements with respect to their operational environment, objects in the environment, and other crewmates. This video analytics module also locates, annotates, and counts how many times the crew performed a specific action, traversed a particular path, or accessed a piece of hardware.
Phase
II work leveraged the Phase I preliminary designs and prototype results. The
team explored machine learning algorithms to detect human presence in a scene
and completed a product that will detect when a person enters a specified
region.

Aims:
A key design challenge for future long-duration exploration missions is determining the appropriate volume of a spacecraft/habitat to accommodate habitability functions and ensure optimal crew health, performance, and safety.

- Develop a constrain-driven, optimization-based model that can be used to estimate and evaluate spacecraft/habitat volume.
- Estimate spacecraft/habitat volume based on mission parameters and constraints,
- Provide layout assumptions for a given volume,
- Assess volumes based on a set of performance metrics, and
- Inform risk characteristics associated with a volume.
- Verify model throughout the model development process.
- Extend to Design Reference Missions to cover other mission durations and parameters.
- Provide validation of the SOLV model.

Aims:
The collection of real-time habitability data can aid in identifying or refining habitability requirements for future flight and surface vehicles or habitats. Observation of how the human crew uses the environment can lead to improved design as well as configuration and layout to help support the crew in the performance of their mission objectives.
- Develop software-based habitability assessment tool with capability to capture self-reported habitability and human factors concerns near real-time through photographs, video, audio, and text to facilitate insight into these reported issues.
- Develop methods for use of hand-held and head-worn video cameras for the targeted collection of video data, with focus on crew-selected habitability and human factors issues, walk-throughs of habitats highlighting key features, and talk-throughs of task performance.
- Evaluate these tools in an analog environment to determine /validate their effectiveness.
Short summary of major findings:
During the NASA Extreme Environment Mission Operations (NEEMO) 16 mission, participants used the Space Habitability Observation Reporting Tool (iSHORT) (the iPad-based habitability assessment tool) as well as targeted video data collection methods (using head-worn cameras and iPad cameras) to report observations during the 12-day mission.
The findings from the Habitability-Human Factors and Habitability Assessment Tool Directed Research NEEMO task have led to the development of new tasks. iSHORT and video methods, along with additional tools, will be further refined as part of the NHV Data Acquisition Tools task. These tools will also be put to use for data collection in the Vehicle NHV and Habitability Assessment (NHV/HAB Assessment) task to document NHV and habitability issues during the 1 year ISS mission, 6 month flight exploratory study, or other venues such as HERA.

Aims:
Space human factors data currently come from crew debriefs. Such debriefs rely on retrospective recall, which could suffer delays of up to six months. Opportunities to discuss human factors issues in detail during these debriefs are limited. In particular, the Space Human Factors Engineering Project is interested in obtaining timely and context-specific human factors incident data. In general, the tool will be used to help detect areas where human factors can contribute to mission success, assess the effects of operational and hardware changes, and complement existing human factors data sources for operations. This research will provide the framework for an on-orbit tool with features not found in a reporting tool to date.
1. To provide crew easy access to the tool at any time to eliminate the need for the crew to recall information retrospectively.
2. Create an easy-to-use data gathering protocol with the following functionalities: Allow data to be entered either as text, audio, and/or video inputs.
3. The ability for the tool to detect a system anomaly automatically and immediately record system status. At a minimum, however, the tool should provide an easily accessible event marker for the crew to mark the context and take a snapshot of the system and operator system status.
4. A user-friendly automated data search engine for extracting meaningful incident information from the raw data. Examples of desirable search schemes include natural language, spatial, temporal searches, etc.
Mitigation/Partial Mitigation: This research will provide the framework for an on-orbit tool with features not found in a reporting tool to date.

Aims:
NASA envisions implementation of an intelligent system that will integrate knowledge of the past and current state of the crew and vehicle in order to appropriately adjust and adapt systems to facilitate mission success for a future state. These complex relationships must be maintained for both routine tasks and more complex tasks. The purpose of this task is to focus research on providing the basis for the development of standards, guidelines and automation tools for an advanced autonomous decision-support system for use by our astronaut population that will reflect both individual and team, real-time human performance support for autonomous spaceflight.
1) Characterize human capabilities and limitations related to potential performance decrements during long duration exploration mission (LDEM) spaceflight as relevant to both routine and complex task performance.
2) Determine appropriate advanced, autonomous intelligent system decision and execution support responses in order to reduce the likelihood or impact of potential decrements in human performance capabilities.
3) Perform integrated assessment of intelligent system responses in order to determine positive or negative interactions and validate recommended approaches.
4) Propose specific updates to existing standards and handbooks to enable implementation of findings for upcoming LDEM systems.

Aims:
Optimal space vehicle design is critical to maximize crew operational efficiency, comfort, and equipment storage. Traditionally, designers and engineers have utilized physical mock-ups early in their design process for task performance and layout evaluation, but high-fidelity mock ups can be costly and time consuming to produce and reconfigure. Therefore, many design decisions have been set in place by the time a high-fidelity mock-up is created, thus diminishing its usefulness. Engineering drawings allow early assessment of vehicle design, but do not allow experimental evaluation with a physical presence of people interacting with the system. Recent advancements in technology have enabled the use of digital designs to ‘virtually’ evaluate habitats in ways not possible with physical mock-ups, for example to explore the vehicle from a simulated microgravity perspective while in 1G. Due to the rapid advancement of technology, practical application of how these capabilities can best be used in the vehicle design process to minimize the potential for costly design errors is still evolving.
Aim 1:
• Characterize, evaluate and contrast a spectrum of reality design tools
Aim 2:
• Evaluate specific design tools or paradigms in which the design tools are used,
Integration: This task may also address several other risks of potential HRP customers such as HHC and ExMC.

Spacecraft and habitats possess unique acoustic
characteristics, and environmental systems produce non-trivial levels of
noise. Acoustic modeling can be used to identify key
noise sources, determine/analyze sub-allocated requirements, keep track of the
accumulation of minor noise sources, and to predict vehicle noise levels at
various stages in the development, first with estimates of noise sources, later
with experimental data. Bench testing of
isolated systems alone is not sufficient as the installation effects are often
not known. Acoustic modeling can be used
to assist with the development and implementation of spaceflight acoustic
materials and to predict their effectiveness including sound containment,
absorption and vibration isolation.

Aims:
Acoustic modeling can be used to identify key noise sources, determine/analyze sub-allocated requirements, keep track of the accumulation of minor noise sources, and to predict vehicle noise levels at various stages in the development, first with estimates of noise sources, later with experimental data. Bench testing of isolated systems alone is not sufficient as the installation effects are often not known.
Acoustic modeling will be used:
- Determined installation effects, reverberation (room geometry) effects, and used to identify propagation paths and possible noise controls, as well as develop an understanding of the resulting acoustic levels in the composite environment.
- Assisted with the development and implementation of spaceflight acoustic materials and predicted their effectiveness including sound containment, absorption and vibration isolation.
The Acoustics Modeling Task completed all if its aims, contributing to closure of the HAB acoustic model gap as written. Acoustic modeling capability to predict resultant levels and spacecraft reverberation characteristics from bench testing of isolated systems, acoustic material sample data, and vehicle geometry has been validated for air-borne noise propagation. Results from this research were provided to the Constellation Program including Crew Exploration Vehicle (CEV) and Altair Lunar Lander Projects so that a more informed oversight of the vehicle development could be implemented with insertion of critical information such as validation of noise allocations for sub-systems, estimation of vehicle noise levels, and identification of potential acoustic problem areas and possible solutions. The capability developed under this project has been used to validate acoustic models and noise control approaches for application to the Orion Crew Exploration Vehicle and Altair Lunar Lander. In addition, applications of the acoustics modeling to interior space design were provided for addition to the Human Interface Design Handbook (HIDH) in the form of recommendations and guidelines. Structural damping measurement, structure-borne noise modeling, and human body acoustic modeling are still in need of development.
