A Micro-Cylindrical Ion Trap (Âµ-CIT) Micro-Mass Spectrometer Instrument System (Âµ-MSIS) for NASA Planetary Explorationdata.nasa.gov | Last Updated 2018-08-02T15:25:43.000Z
<p>The goal of this follow-on early stage innovation activity is to advance the development of new, extremely small, low power, and low cost “micro” mass spectrometer instrument systems (μMSIS) through the application of MEMS design and fabrication, and microsystem component integration and packaging, toward deployment on distributed planetary payload platforms. This work attains significant early impact due to our recently-awarded ASTID project (van Amerom et al.), to develop the core chip-based micro cylindrical ion trap (μ-CIT) mass analyzer at GSFC. In particular, this work will enable early, coincident design and development of the critical microsystem integration and packaging that is required to achieve the final level of miniaturization offered by this core μ-CIT technology. We therefore propose to develop a MEMS μMSIS packaging concept that is modular and flexible to further integration of a micro gas chromatograph, micro vacuum chamber and microelectronic components, into a complete instrument system.</p> <p>This activity will significantly increase the fidelity of the miniaturized component packaging of the μ-CIT mass spectrometer assembly. Our design approach emphasizes the smallest feasible footprint, combining MEMS MS component integration, and the use of ultra-high vacuum (UHV) materials. This activity will significantly increase the fidelity of the miniaturized component packaging of the μ-CIT mass spectrometer assembly. Our design approach emphasizes the smallest feasible footprint, combining MEMS MS component integration, and the use of ultra-high vacuum (UHV) materials and techniques for fabrication of the final package. Final package systems designs and component parts have been fabricated using micro fabrication capabilities and MEMS processing. Assembly and integration of the package takes advantage of existing packaging expertise, materials, and tooling. The component packaging system will be evaluated for form, function, outgassing, and vibration here at GSFC.</p>

M4 Engineering proposes to implement physics-based, multidisciplinary analysis and optimization objects that will be integrated into a Python, open-source framework and used in a wide variety of simulations. The integrated objects will perform discipline-specific analysis across multiple flight regimes at varying levels of fidelity. The process will also deliver system-level, multi-objective optimization. Addressing physics-based, system-level objectives that span more than one discipline will have profound effects on improving decision-making abilities during the conceptual design phase when evaluating advanced technological concepts. In the proposed effort, existing capabilities will be leveraged to create a high fidelity, physics based, multidisciplinary analysis and optimization (MDAO) system. This proposed work will compliment M4 Engineering's expertise in developing modeling and simulation toolsets that solve relevant subsonic, supersonic, and hypersonic demonstration applications.

<p>This multi-year IRAD proposal, in a strategic partnership with University of Maryland (UMD) and Bowie State University (BSU), creates a collaborative virtual reality (VR) tool for concept design and assembly in VR from a database of pre-defined "parts", enabling engineers and scientists to work in a shared VR environment, as part of a concept design or pre-phase A proposal process. The proposal will define a domain agnostic database for specifying a set of physical, off-the-shelf, plug and play parts with reduced detail shape/CAD files and migrate existing domain-specific GSFC database(s) to this format, to quickly realize a collaborative, model-based VR engineering environment for prototyping, assembly mockup, and visualizations for pre-phase A work.</p><p>This proposal will create a collaborative VR environment for early stage design and assembly of hardware projects from pre-defined, off-the-shelf parts as part of a concept design or pre-phase A proposal process.

We will design and formally verify a VLIW processor that is radiation-hardened, and where the VLIW instructions consist of predicated RISC instructions from the PowerPC 750 Instruction Set Architecture (ISA). The PowerPC 750 ISA is used in the radiation-hardened RAD750 flight-control computer that is utilized in many NASA space missions, including Deep Impact, the Mars Reconnaissance Orbiter, the Mars Rovers, and is planned to be used in the Crew Exploration Vehicle (CEV). The VLIW processor will have reconfigurable functional units and specialized instructions that will be optimized for Software Defined Radio applications. The radiation-hardening will be done at the microarchitectural level with a mechanism that will allow the detection and correction of all timing errors---caused not only by radiation, but also by variations in the voltage, frequency, manufacturing process, and aging of the chip. The binary-code compatibility of the resulting VLIW processors with the PowerPC 750 ISA will allow them to seamlessly execute legacy binary code from previous space missions. We have made critical contributions to the fields of formal verification of complex pipelined microprocessors, and Boolean Satisfiability (SAT), and have developed highly efficient Electronic Design Automation (EDA) tools that we will use.

Assistive Free-Flyers (AFFs) are flying robots designed to share the living space with human astronauts in orbit. These robots have shown the potential to assist astronauts with tasks such as surveillance, inspection, and mapping. However, AFFs are currently designed without manipulation capabilities, and can thus be deployed mainly for sensing and observation. In this project, we aim to provide AFFs with the capability to physically interact with the environment through manipulation. We plan to equip AFFs with compact yet dexterous robotic arms and hands developed in this project, along with the planning and control methods needed to operate them. We aim to demonstrate new capabilities on tasks such as object acquisition and transport, part insertion and extraction, button or lever operation, docking and perching. We believe these abilities will greatly increase AFFs' reach, literally and figuratively.

Low Cost Automated Manufacture of High Efficiency THINS ZTJ PV Blanket Technology (P-NASA12-007), Phase Idata.nasa.gov | Last Updated 2018-07-19T09:38:25.000Z
NASA needs lower cost solar arrays with high performance for a variety of missions. While high efficiency, space-qualified solar cells are in themselves costly, > $250/Watt, there is considerable additional cost associated with the parts and labor needed to integrate the Photovoltaic Assembly. The standard approach has evolved with only minor changes, sacrificing cost because of risk aversion. Integration cost can be as much as double the bare cell cost – i.e. >$500/watt. Dramatic cost savings can be realized through manufacturing engineering of more efficient automated assembly processes. If the design of the Photovoltaic Assembly could be modified to be compatible with conventional and automatable electronic assembly and terrestrial solar panel assembly approaches, there could be considerable cost savings. There are many additional benefits with automation which include higher quality and consistency. This can reduce failures, increase production throughput, speed turnaround, and improve overall reliability. Cost and quality improvements can be realized on both thin and rigid arrays, increasing current capabilities, and enabling future high power missions. The benefits of automation are enhanced by the need for high power generation in support of energy intensive space missions. A 300kW array at $500/W would cost $150M just for the solar cell integrated array panels. A $150/W cell integration cost reduction would translate into savings of $45M, before considering the immediate and substantial benefits in consistency, reliability, and schedule. The Phase I effort demonstrates feasibility of a low cost array using an automated and integrated manufacturing approach, performed on an automation friendly solar cell, verified with environmental testing, and is used to predict array cost for a high power mission. Meeting these technical objectives will demonstrate reduced cost and justify a Phase II SBIR program preparing for a flight experiment.

ZONA Technology, Inc. (ZONA) proposes a R&D effort to develop a Unified Nonlinear Flight Dynamics and Aeroelastic Simulator (UNFDAS) Tool that will combine proven simulation and visualization techniques to accurately match in-flight recorded dynamic behavior of an air vehicle. ZONA proposes to develop the UNFDAS Tool through a blend of state-of-the-art aerodynamic model updating and control-oriented techniques. It blends mathematically sound flight dynamics and aeroelastic modeling approaches with CFD, wind-tunnel or flight-test data. The end product is a nonlinear dynamic tool capable of simulating the key aeroelastic coupling mechanism between structural modes and unsteady aerodynamic effects with classical rigid-body dynamics. Feasibility studies are proposed to validate the UNFDAS Tool using a suite of actual data from flying qualities and flutter flight tests. This enabling technology will be invaluable to the flight test community by accurately simulating the air vehicle responses to different input commands, and then identifying the critical flying conditions before actual flights are performed. Marketing the resulting software package will be simplified by taking advantage of ZONA's current extensive customer list. ZONA Technology's reputation and track record in supporting the aerospace industry and government with ZONA codes can assure the success of the commercialization plan.
