T1.01: Launch Vehicle Propulsion Technologies
Description: Lead Center: MSFC Participating Center(s): SSC OCT Technology Area: TA01 Heavy lift launch vehicles envisioned for exploration beyond low Earth orbit (LEO) will require large first stage propulsion systems. For some heavy lift vehicles, the total thrust produced at lift-off will exceed 6 million pounds. There are currently available practical propulsion options for such a vehicle. However, the cost for outfitting the booster with the required propulsion systems is in the hundreds of millions of dollars. This cost severely limits what missions NASA can perform. Low cost design concepts and manufacturing techniques are needed to make future exploration affordable. This topic seeks technologies that will fulfill the following objectives: • Development of propulsion concepts whose cost is less than 50% of currently available but with similar performance. • Development and demonstration of low-cost manufacturing techniques. • Techniques for evaluating and analyzing low-cost, easily manufacturable design concepts. Example technologies of interest include: • Ablative materials and manufacturing techniques. • Innovative chamber cooling concepts that reduce manufacturing complexity without reducing performance. • Low-cost nozzle materials, manufacturing techniques, and coatings. • Ignition concepts that require low part count and/or low energy to be used as either primary or redundant ignition sources. • Manufacturing techniques that lower the cost of manufacturing complex components such as injectors and coolant channels. Examples include, but are not limited to, development and demonstration of rapid prototype techniques for metallic parts, powder metallurgy techniques, and application of nano-technology for manufacturing of near net shape manufacturing. • Increased efficiency and fidelity analysis tools. The development of future propulsion systems for deep-space exploration are directly dependent on the development of technologies such as those listed. Furthermore, affordable, reliable access to space technology is a strong need across all of NASA’s space exploration activities (HEOMD, OCT, SMD). While revolutionary advances in launch vehicle technologies are not foreseen to be developed in the immediate future, a practice of employing methodical continuous technology development in the direction of lowering the cost and improving the reliability of launch propulsion systems will addresses this critical need of lowering the cost of earth-to-orbit launch systems and capabilities.

T10: Nanotechnology
Description: Nanotechnology, addresses four subareas: engineered materials and structures, energy generation and storage, propulsion, and sensors, electronics, and devices. Nanotechnology describes the manipulation of matter and forces at the atomic and molecular levels and includes materials or devices that possess at least one dimension within a size range of 1-100nm. At this scale, quantum mechanical forces become important in that the properties of nano-sized materials or devices can be substantially different than the properties of the same material at the macro scale. Nanotechnology can provide great enhancement in properties, and materials engineered at the nano-scale will shift the paradigm in space exploration, sensors, propulsion, and overall systems design.

T10.01 : Innovative Refractory Materials for Rocket Propulsion Testing
Description: Lead Center: SSC Participating Center(s): KSC OCT Technology Area: TA10 NASA has identified the advancement of materials as a critical technological need in supporting future space flight and rocket test operations. Specifically, innovative materials for thermal management applications have been targeted with the additional goal of furthering nanotechnology. With the development of these new multi-functional, high-temperature materials comes the requirement for verification and validation of the predictability of their thermal behavior. The current subtopic is to develop innovative refractory materials which use nano-particle additives and/or unconventional non-cement based refractories that can withstand the extreme plume heating environments experienced during rocket propulsion testing. The material should provide a revolutionary improvement over conventional castable refractories. Explicitly, the nano-based or multi-functional material should provide substantial improvements in several of the following areas: • Compressive and flexural strength. • Thermal, abrasion and corrosion resistance. • Operating temperatures at or above 4000 °F. • Excellent workability for potential lining of vertical walls/pipes. • Ultra-low porosity. Demonstration of the performance of these materials in environments similar to rocket plume environments will be a critical aspect of the success and usefulness of the proposed technology. In addition, verification and validation of the predictability of the material behavior during ablative heating is of high importance to the mission of NASA. Other potential applications of nano-particle/multi-functional refractory materials might be use in expendable (or even reusable) rocket engine thrust chambers, control system thrusters, and nozzles to extend the life of the testing infrastructure and components. These engine components could be for launch or in-space propulsion systems. This application would add a requirement to be light weight and provide manufacturability for use in coatings or production of components.

T11.02 : Distributed Simulation for Design and Manufacturing
Description: Lead Center: KSC OCT Technology Area: TA11 NASA is embarking on missions to new environments with new technologies and new systems to take us far beyond where any human has gone before. Understanding, managing and leveraging the associated complexity will require new tools, new methods, new ways of managing data and, in the long run, entirely new types of data as well. Simulation plays a key role in each of these areas with advanced tools and processes already in use to define architectures, study options and integrate alternatives into the overarching plan. However, today’s tools , and even tomorrows tools, lack the ability to integrate and share information on the physical and temporal scale necessary to efficiently and effectively enable these systems. Desired product is a prototype suite of tools, systems and processes to allow researchers, innovators and operational organizations to share simulation based needs, technologies, concepts and opportunities over large distances (planets) and large increments of time (decades). The system should utilize existing Industry and NASA standards and interfaces for simulation data, suggest new ones, or both. Emphasis should be placed on interfaces like XML to both extend the lifecycle of data elements into the 50 year range as well as interface with the emerging set of NASA tools. Distributed Simulation of this nature has been identified by the National Research Council as one of the 83 high priority technologies for NASA as a part of the OCT roadmap team efforts. It is a part of TA 11 (modeling, simulation, information technology and processing) and is one of the 4 high priority technologies identified for that roadmap. It directly supports any complex design and development efforts directly and supports technology push and pull by better communicating programmatic needs and technology solutions in relevant operational environments.

T12.02 : Materials and Manufacturing Technologies
Description: Lead Center: MSFC Participating Center(s): GRC, JSC, LaRC OCT Technology Area: TA12 NASA’s science and exploration missions continue to seek materials and manufacturing techniques and capabilities that will allow missions of increased capability and reduced costs. These future missions depend highly on advancements such as lighter and stronger materials and manufacturing methods. Materials and manufacturing technologies have high value and make a significant contribution to the interests of others outside of NASA, specifically those that address broader national needs as well as the needs of the commercial space industry. The portfolio of advanced materials and manufacturing technologies is extremely broad and cross-cutting with complex interactions between core disciplines (e.g., materials and structures), applied R&D, innovation, and production. In reference to the recent report from the National Research Council on the Space Technology Roadmaps produced by NASA’s Office of Chief Technologist, the report ranks lightweight and Multifunctional Materials and Structures as an area of high priority development to be emphasized over the next 5 years. This topic seeks technologies that support these needs: • Lightweight and multifunctional materials concepts including, advanced composite, metallic, and ceramic materials that significantly enhance future exploration and science missions and enable new missions. • Digital/Model-based Manufacturing technologies that enable cost-effective manufacturing for reliable high-performance structures and made in low-unit production, including in-space manufacturing. • In-space and additive manufacturing that offers the potential for game-changing weight savings and new mission opportunities. University researchers are well-positioned to make a positive contribution within the time and funding allocation vis-a-vis a concept demonstration, enhancement of an existing component through a clever innovation, working prototype, etc. Also, this topic of materials and manufacturing technologies supports and is closely aligned with the President’s National Strategic Plan for Advanced Manufacturing.

T13.01 : Risk Engineering, Sciences, Computation, and Informed Decisions
Description: Lead Center: JSC Participating Center(s): KSC OCT Technology Area: TA13 Human spaceflight missions in the early twenty-first century are still inherently complex and risky. While it takes a very talented and courageous flight crew to achieve a mission’s objectives, it takes many more people on the ground to plan, prepare, and support the flight crew during the mission to ensure the safety of the crew and the success of the mission. For every human spaceflight mission, many decisions are made before each mission and more decisions are made during the mission in responding to changes in the environments or space vehicle systems. As in many other complex operations in harsh environments on Earth, labor-intensive information research and analyses is necessary to weigh the benefits versus the risks of each alternative in order to make accurate risk-informed decisions. Often these decisions need to be made in a short period of time before space vehicle systems are out of consumables or the risk of continuing the mission becomes unacceptable. Sometimes a decision that reduces risk in one limited perspective or frame of reference inadvertently increases system-level or end-to-end mission risk due to impacts that were not foreseen due to limited human ability to consider and assess all relevant data. This STTR subtopic seeks to advance the state-of-the-art in knowledge management, information management, information technology, and artificial intelligence leading toward the ability for computer systems to assist humans in timely and correctly identifying, quantifying, characterizing, mitigating, and communicating risks to inform decision makers of risks before the decisions are made. Application of advanced computer-based decision support technologies to identify and assess relevant data, identify alternatives, and model consequences will significantly reduce the cost of development, deployment, and sustainment of complex space systems and significantly increase safety of crew during space missions. Below are some examples of technologies that would be appropriate for this sub-topic: • Timely Risk Identification - For several decades, the Failure Modes and Effects Analysis has been used to identify risks inherent in space system designs. Analysis results are frequently not available until the system design has matured to the point where it is ready for final development, test, and or deployment. Changes late in the design lifecycle often cannot be accommodated due to significant schedule delay and cost increase. Although designing out hazards is the most effective and preferred means of control, mitigations for identified risks at this time are usually limited to procedural controls which require recurring attention throughout the operational phase. This often results in operational complexity, higher risk, and higher sustaining cost. An automated failure modes and effects simulation technology would be a game-changer by identifying safety and technical risks of the design early and quickly so that design changes or trades may be made to eliminate these risks at a much lower lifecycle cost and significantly improve safety and system reliability. • Risk-Informed Decision Making - As space systems become more complex and human space exploration destinations get farther away from Earth, the flight crew may be forced to make timely decisions in responding to imminent hazardous conditions without the assistance of the ground crew. Risk-informed decision support technologies would assist the flight crew by suggesting possible actions that have the highest probability of success. • Context-Based Software Risk Modeling - Space system designers are considering incorporating or increasing levels of automation in their systems to achieve a sustainable human space exploration program. Although the desired outcome is a net reduction of overall mission risk, more automation will result in increasing the complexity of the software systems, and thus increase the proportion of risk attributable to software faults as a component of system risk. NASA is seeking Context-Based Software Risk Model technologies to address the risks of software required functionality that would be compatible and consistent with the standard Probabilistic Risk Assessment methodology now employed by NASA. An effective integration of the PRA and CSRM techniques would facilitate comparative evaluations of automation design options for effectiveness in reducing mission risks.

T15.01 : Cross cutting Avionics for Beyond Earth Orbit Space Exploration
Description: Lead Center: JSC Participating Center(s): KSC, MSFC As NASA human exploration and science missions move further from Earth and become increasingly more complex, they present unique challenges to the on-board avionics systems. Avionics systems in space vehicles are significant size, weight and power (SWaP) as well as cost drivers. Future destinations such as L2, near-earth asteroid, Mars, etc. are characterized by long durations, vast distances and harsh environments and call for significant advances in on-board processing, autonomy, reliability, fault-tolerance and redundancy. Advanced technologies and approaches to avionics systems and its components are needed to support these challenging mission requirements and to safely bring crew back to Earth. Avionics provides cross- capabilities across different sub-systems and is a prime candidate for commonality between different missions and programs leading to savings in the design, development and testing, logistics (sparing, reuse, and re-purposing of hardware) and operational costs. To support exploration mission objectives and requirements, advances in emerging avionics technologies (processors, networks and network devices, memory cards, human interfaces including visual, tactile and auditory interfaces, etc.) and associated foundational technology are required. Areas addressing miniaturization, radiation and extreme temperature environments such as radiation hardened by design, Rad-hard extreme temperature technology, and electronics packaging, etc. are of particular interest. The focus of this subtopic is to support the development and advancement of cost-effective avionics technologies while keeping a unified approach to promote commonality of systems between multiple missions and/or programs. The ultimate goal is to develop a common avionics framework and a catalog of components that can be integrated into a space vehicle in the next 6-10 years.

T15.02 : Autonomous Systems for Atmospheric Flight
Description: Lead Center: LaRC Participating Center(s): KSC With increasing levels of automation capabilities in the aviation arena, provides unique opportunities and challenges for civil aviation, and the aerial transport communities. Flight will be transformed as these capabilities mature and evolve in to integrated systems. In particular, autonomous and robotic, manned and unmanned civil aircraft systems will lead to a plethora of new markets, vehicle, and missions. These new systems with broad range of capabilities, and a huge diversity of shapes and sizes, must safely utilize the future National Airspace System. Both operational and machine autonomy will require tremendous breakthroughs through the new technology frontiers in machine intelligence, autonomy, robotics, and inter-connections of these technologies. Breakthroughs in these areas could lead to such societal capabilities as autonomous cargo carrying, surveillance, air taxis, small unmanned civil aircraft, Zip aircraft, on-demand VTOL aviation, airborne wind energy platforms and a host of other emerging distributed aviation systems. The goal of this topic area is to develop technologies and capabilities that will lead to fully autonomous systems that are able to learn and adapt to changes in their environment that were not predicted, and yet still accomplish the mission goals, with minimal or no human involvement required. For purposes of this solicitation, autonomous vehicles have varying levels of autonomy and range from automated capability to fully autonomous flight where the system has the ability to learn, reason, and adapt. Military applications have demonstrated the ability to do automated flight but their use in civil aviation requires additional research and development. The primary interest of this sub-topic is to advance the technologies for robotic and autonomous vehicle perception, cognition, as well as system integration. Proposals should be written around one of the following themes described below: • Autonomous or robotic pilot - Autonomous systems can be applied far beyond remotely piloted aircraft. Maximum machine effectiveness can only be realized through vehicle autonomous systems ability to learn, reason and adapt. Current practice is to have a reliance on stored information, which is complemented by GPS position information. If there is an on-board, real-time means to sense and react to the local environment (including air and ground features and traffic), then autonomous and robotic air-vehicle can be fully utilized. But addressing how adaptive systems can still be ‘trusted’ in critical flight environments and achieve FAA certification is a technical issue that must be resolved. Proposals are sought to develop innovate approaches and enabling technologies for autonomous, robotic, and embodied intelligent air-vehicles. Example scenarios could include but are not limited to carrying passengers and cargo through the NAS, search, rescue, and surveillance operations, and sentries to patrol coastal waters, and land borders. Proposal should consider perception, cognition, as well as GPS enabled, GPS-denied, and cooperating and non-cooperating traffic environments. • Autonomy for flight, the robotic test pilot. Adaptive and robust controllers designed to autonomously fly and optimize around multiple vehicles. Products would be aerodynamic coefficients such as coefficient of lift and drag as well as controller effectiveness. • Autonomous intelligence, surveillance and reconnaissance. A next generation system would entail a “smart payload” with a UAS designed around it to accomplish specific missions. Example missions might include, but are not limited to disaster relieve, fire monitoring, launch vehicle tracking, or hurricane tracking. The payload would ultimately permit autonomous target acquisition, tracking, and aircraft attitude/orientation to optimize data collection, or ensuring mission completion. Initial activities would include an assessment of current technology capabilities that could be compared to requirements for a next generation autonomously controlled sensor and platform system to identify technology gaps and lay out a technology development road map. Subsequent activities would include component and system developments and integration in accordance with the road map, leading to the development of a prototype system capable of integrating with a UAS.

This subtopic addresses the potential for deriving power from waste engine heat, warm soil, liquids, kinetic motion, piezoelectric materials or other naturally occurring energy sources, etc. (re: TA-3; 2.2.1.1). Development of energy harvesting (both capture and conversion) technologies would also address the national need for novel new energy systems and alternatives to reduce energy consumption. Areas of special focus for this subtopic include consideration of: • Innovative technologies for the efficient capture and/or conversion of acoustic, kinetic, and thermal energy types. • Technologies which can work either under typical ambient environments for the above energy types and/or under high intensity energy environments for the above energy types as might be found in propulsion testing and launch facilities. • Innovations in miniaturization and suitability for manufacturing of energy capture and conversion systems so as to be used towards eventual powering of assorted sensors and IT systems on vehicles and infrastructures. • High efficiency and reliability for use in environments that may be remote and/or hazardous and having low maintenance requirements. • Employ green technology considerations to minimize impact on the environment and other resource usage. Rocket propulsion test facilities within NASA provide excellent test beds for testing and using the innovative technologies discussed above because they offer a wide spectrum of energy types and energy intensities to capture and convert. Additional Federal mandates require the optimization of current energy use and development of alternative energy sources to conserve on energy and to enhance the sustainability of these and other facilities.

T4.01 : Information Technologies for Intelligent and Adaptive Space Robotics
Description: Lead Center: ARC OCT Technology Area: TA04 The objective of this subtopic is to develop information technologies that enable robots to better support space exploration. Robots are already at work in all of NASA's Mission Directorates and will be critical to the success of future exploration missions. The NASA "Robotics, Tele-Robotics, and Autonomous Systems" roadmap (TA04) indicates that extensive and pervasive use of robots can significantly enhance exploration, particularly for missions that are progressively longer, complex, and operate with fewer ground control resources. Intelligent robots can do a variety of work to increase the productivity of planetary exploration. Robots can perform tasks that are highly-repetitive, long-duration, or tedious. Robots can perform tasks that help prepare for subsequent human missions. Robots can perform "follow-up" work, completing tasks started by astronauts. Example robotic tasks include: • Scouting. • Site surveys. • Sampling. • Payload deployment. • EVA close-out work. The performance of intelligent robots is directly linked to the quality and capability of the information technologies used to build and operate them. Thus, proposals are sought that address the following technology needs: • Advanced user interfaces for telerobotics, which facilitate distributed collaboration, geospatial data visualization, summarization and notification, and robot tasking. This does NOT include user interfaces for direct teloperation (e.g., joystick-based rate control), telepresence, or immersive virtual reality. The primary objective is to enable more effective and efficient interaction with semi-autonomous telerobots. (TA04 roadmap technical area 4.4). • Mobile robot navigation (localization, hazard detection and avoidance, etc) for operations in man-made and unstructured environments. Emphasis on multi-sensor data fusion, obstacle detection, and proximity ops.

This includes frameworks for adjustable autonomy, on-board health management and prognostics, automated data triage, and high-performance robot middleware. The primary objective is to facilitate the creation, extensibility and maintenance of complex robot systems. (TA04 roadmap technical area 4.5).

Description: Lead Center: DFRC Participating Center(s): ARC, JPL, LaRC OCT Technology Area: TA04 This subtopic addresses advanced control-oriented techniques for dynamic servoelastic (DSE) terrestrial, planetary, and space environment flight systems using distributed network sensor and control systems. Methods include modeling, simulation, optimization and stabilization of DSE systems to actively and/or adaptively control structural dynamic geometry/topology, vibration, atmospheric and intraspace disturbances, static/dynamic loads, and other structural dynamic objectives for enhanced dynamic servoelastic performance and stability characteristics. • DSE control for performance enhancements while minimizing dynamic interaction. • Flexible aircraft and spacecraft stabilization and performance optimization. • Modeling and system identification of distributed DSE dynamics. • Sensor/actuator developments and modeling for distributed DSE control. • Uncertainty modeling of complex DSE system behavior and interactions. • Distributed networked sensing and control for vehicle shape, vibration, and load control. This subtopic also addresses capabilities enabling design solutions for performance and environmental challenges of future air and space vehicles. Research in revolutionary aerospace configurations include lighter and more flexible materials, improved propulsion systems, and advanced concepts for high lift/performance and drag/energy reduction. This subtopic targets efficiency and environmental compatibilities requiring performance challenges and novel control-oriented techniques for aero-servoelastic considerations which are gaining prevalence in advanced aerospace flight vehicles, atmospheric and extra-terrestrial. Technical elements for the Phase I proposals may also include: • Mission/maneuver adaptivity with dissipative optimal energy-force distribution. • Data-driven multi-objective DSE control with physics-based sensing. • Robust sensing-control-communication networks for sensor-based distributed control. • Compressive information-based sensing and information structures. • Evolving systems as applied to self-assembling and robotic maneuvering. • Scalable and evolvable information networks with layering architectures. • Modular architectures for distributed autonomous aerospace systems. • Multi-objective, multi-level control and estimation architectures. • Distributed multi-vehicle dynamics analysis and visualization with complex simulations. Development of distributed sensory-driven control-oriented DSE systems is solicited to enable future flight vehicle concepts and designs that manage structural dynamic uncertainty on a vehicle's overall performance. Proposals should assist in revolutionizing improvements in performance to empower a new generation of air and space vehicles to meet the challenges of terrestrial and commercial space concerns with novel concepts and technology developments in systems analysis, integration and evaluation. Higher performance measures include energy efficiency to reduce fuel burn and operability technologies that enable information network decompositions that have different characteristics in efficiency, robustness, and asymmetry of information and control with tradeoff between computation and communication. Advanced mission applicability in Phase II should show the ability of aerospace GN&C systems to achieve mission objectives as a function of GN&C sensor performance, vehicle actuation/power/energy, and the ability to jointly design them as onboard-capable, real-time computing platforms with applicable environmental effects and robust guidance algorithms. Goals are to: • Provide capabilities that would enable new projects/missions that are not currently feasible. • Impact multiple missions in NASA space operations and science, earth science, and aeronautics. • Be influential across aerospace and non-aerospace disciplines with dynamic interactions. New technologies proposed should have the potential to impact the following NASA missions: • Data availability for science missions. • Mission planning. • Autonomous rendezvous/docking technology. • Environmental monitoring for human habitation. Apart from NASA missions, the aeronautics technology could be adapted for development and use in autonomous operation of wind/ocean energy and smart space power grid systems in dynamic environments. There are number of advantages to exploring this subtopic technology: • Increase in autonomy and fuel efficiency of coordinated robotic vehicles and sub-components. • Improved science, atmospheric, and reconnaissance data. • Cost, risk and reliability of flight vehicles for a terrestrial, planetary, or space mission. • Inter-networks with improved dynamic behavior.

T4.03 : Extreme Particle Flow Physics Simulation Capability
Description: Lead Center: KSC OCT Technology Area: TA04 Advanced computer modeling software is sought to provide the ability to predict the flow of granular materials in space and/or planetary environments. Proposals are sought for software capable of handling one of more of the following applications in one or more relevant environments for space exploration: • Rovers driving on planetary regolith. • Rocket engines blowing planetary regolith. • Excavators and resource extraction systems moving and conveying planetary regolith. • Technologies that burrow or drill into planets and asteroids for scientific access. • Transport of granulated metal hydrides as hydrogen fuel systems. • 3-D printing technologies that use powders in space manufacturing. The relevant environments, or “extreme environments,” are the environments encountered in space exploration but not normally encountered in terrestrial industry. These may include supersonic gas flow, rarefied atmospheres, low gravity, or zero gravity, where we have less terrestrial experience in the behaviors of granular flow. This modeling capability will be useful as part of the engineering design and checkout process for aerospace systems, notably the technologies that will interact with planetary soil. The technologies that are sought are different than prior state-of-the-art (SOA) in granular modeling insofar as prior SOA often utilized ad hoc algorithms, empirical relationships, and “rules of thumb” to estimate granular behavior, and relied on “tweaking” model parameters until the modeling approximated experimental data over a limited range of application. (Granular flow is challenging due to meso-scale granularity that produces a bewildering array of emergent, macro-scale phenomena.) Prior SOA was therefore not truly predictive and therefore of limited power, but it was useful for modest extrapolation around a range of behaviors that has been previously validated by experiment. In contrast, advances in granular physics theory over the past 5 years are surprisingly far ahead of expectations and it is now possible to develop new modeling methods that are truly predictive for the previously unpredictable regimes of solid-like, fluid-like and gas-like flow of granular materials integrated with gas flow and mechanical devices, including extreme environments (rarefied/supersonic flow, planetary surfaces, etc.). While it is still too early to expect a software package to be capable of modeling all granular phenomena across all ranges of behavior and all environments, it is now possible to create software packages capable of handling one or more of the areas that are important to NASA and necessary for NASA’s mission. Relevant advances in granular physics that may be incorporated into the new software may include (but are not limited to): • Granular gas theory equivalent to Boltzmann’s Transport Equation. • Application of granular gas theory to continuous particle size distribution to predict transport coefficients. • Successful prediction of dense flow as a function of particle shape. • A useful technology will be one that can be applied in the real-world engineering design process for the design and checkout of NASA spaceflight technologies.

T5: Communication and Navigation
Description: Communications and Navigation Systems, consists of six technology subareas: optical communication and navigation; radio frequency communication; internetworking; position, navigation and timing; integrated technologies; and revolutionary concepts. Communication links are the lifelines to spacecraft, providing commanding, telemetry, and science data transfers as well as navigation support. Therefore, the Communications and Navigation Systems Technology Area supports all NASA space missions. Advancement in communication and navigation technology will allow future missions to implement new and more capable science instruments, greatly enhance human missions beyond Earth orbit, and enable entirely new mission concepts.

T5.01 : Autonomous Navigation in GNSS-Denied Environments
Description: Lead Center: LaRC Participating Center(s): KSC OCT Technology Area: TA05 Current NASA research/development and mission capabilities for exploration of remote planetary surfaces and UASs are primarily focused on automated telerobotic systems dependent on human control. More fully autonomous systems will be required for future missions, particularly where communications with Earth may be limited, unavailable for extended periods of time and have significant delays. This subtopic is to investigate the autonomous navigation capabilities required for land and possibly aerial vehicle operation in areas lacking GNSS and/or magnetic compass to expanded exploration roles within planetary environments. A specific area of interest is to investigate biologically inspired algorithms and capabilities, such as techniques used by insects, such as Honey Bees, to accomplish this goal. Optical flow, image motion across the field of vision, offers unique capabilities for hazard detection and avoidance, landmark navigation, distance judgment, cave navigation, speed regulation, and visual odometry. Current technology is very computationally intensive. It is desired that with hardware support, high speed optic flow measurements can be obtained to speed up and simplify the extraction of motion information from the visual scene, which would both enhance obstacle and hazard detection and avoidance, as well as speed up the navigation process. This will be very critical if VTOL flight [on Mars] can be achieved, as a fuel-limited, in-motion VTOL vehicle is ill positioned to wait for a complicated and time consuming image analysis to be accomplished. Additionally, current laser scanner/imaging technology used for generating terrestrial 3-D maps have mass and power requirements that are excessive for smaller planetary robotic exploration systems. Low mass, low power 3-D mapping systems accommodated on planetary missions could be employed to support autonomous vehicle navigation and maneuvering operations. One example would be a parent vehicle that could launch multiple smaller vehicles that would autonomously explore larger regions and then navigate back to the parent vehicle to transmit data and refuel. In addition to navigation, these vehicles could gather detailed, photorealistic 3-D maps that can be fused with associated science data and used by scientists, students, and the general public for “participatory exploration” activities. Initial activities would include an assessment of current technology capabilities that could be compared to requirements to identify technology gaps and lay out a technology development roadmap. Subsequent activities would include component and system developments in accordance with the roadmap, leading to the development of a prototype system capable autonomous navigation in environments that do not allow GNSS or magnetic compass navigation and have limited or no communication between vehicles.

T6.01 : Space Synthetic Biology and Food Production Technologies for Space Exploration
Description: Lead Center: ARC Participating Center(s): JSC, KSC OCT Technology Area: TA06 Space Synthetic Biology: Synthetic Biology (SB) provides a unique opportunity to design organisms that reliably perform necessary functions for future exploration activities. NASA is interested in harnessing this emerging field to create technological advances that will benefit both spaceflight and future surface missions in a variety of enabling areas. Of particular interest is the use of SB, including bioelectrical systems/organisms and technologies, that will reduce the required up-mass and dependence on consumables, resupply, and energy. This may be done through in situ resource utilization (ISRU) and/or the development of more sustainable and efficient systems. Specifically, ISRU technologies should address how SB-based systems may use in situ resources (e.g., regolith, CO2) to fabricate advanced materials and/or produce building materials, fuels and plastics. SB-based food production is another area of interest. SB based Environmental Control and Life Support Systems (ECLSS) should focus on increasing efficiency/reliability/regenerability of air, water and waste management. Prototype hardware to support SB-based systems and modified cell lines - (particularly BES) with potential application for ISRU, ECLSS and food production would all be of interest to NASA. A prototype DNA “writer” technology for transmitting new DNA sequences to SB systems would be considered an enabling technology. Food Production Technologies for Space Exploration: NASA is interested in food production and related food safety technologies for both near term transit (μ-gravity) missions and eventual surface missions (fractional gravity). Of special interest is the use of plants (e.g., crops) to photosynthetically produce food, and contribute to cabin O2 production and CO2 removal. Food production technologies should address how quantum and/or radiation use efficiency will be improved to reduce energy costs, including advanced lighting concepts. Improved concepts for gravity independent watering techniques will also be needed. Complementary approaches might consider selecting or adapting the plants for optimal performance for the constraints of space environments, which could include smaller growing volumes, micro to fractional g, elevated radiation, super-elevated CO2 concentrations (e.g., >5000 ppm or 0.5 kPa), and narrow band light spectra. Related technologies for sanitizing or reducing the microbial loads to reduce the safety risks of preparing and consuming space grown foods are also needed. All systems should consider minimizing power, mass, consumables, and biologically produced waste, while maximizing reliability and efficiency.
