World-Class Visualizations in GMAT, Phase I

Today's mission designers rely on state of the art tools with modern GUI elements and real-time 3D interactive graphics to visualize their trajectories and orbit control strategies. One such tool, NASA GSFC's General Mission Analysis Tool (GMAT), offers advanced mission design and optimization capabilities with a flexible GUI. However, its current 3D graphics are lacking in both the quantity and quality of graphical components as well as the maturity of its visualization architecture. Fortunately, GMAT's underlying flexible and Open Source software architecture was designed to facilitate modular improvements. We propose to provide GMAT with world-class visualization capabilities and a graphics architecture that can adapt to future visualization technologies by replacing the existing basic graphics code with the OpenFrames visualization software. OpenFrames is an Open Source API that allows simulations to incorporate high-performance interactive 3D visualizations without requiring significant architecture changes. In this research, we develop comprehensive requirements for GMAT's visualization needs, create a plan to integrate OpenFrames into GMAT, demonstrate a prototype of OpenFrames in GMAT, and compare the performance of OpenFrames to the existing basic visualizations in GMAT. This research will not only bring GMAT visualizations up to par with other mission design tools, such as AGI's STK/Astrogator and NASA JSC's Copernicus, but will also allow GMAT to support cutting-edge technologies such as interactive visual trajectory design and virtual reality environments such as the GSFC CAVE. In turn, this will increase GMAT's user base and increase its utility for future NASA missions, such as Decadal Survey and Discovery class missions that require high-fidelity simulations paired with truly interactive 3D visualizations.

Inflatable Air Beam Standard Interface Connector

<p>The project will develop a system of 3D-printed connectors that can be used as a kit of parts to connect inflatable air beams to form a variety of spacecraft interior outfitting components.&nbsp; Examples of inflatable IVA structures that can be assembled include crew quarters, waste &amp; hygiene compartment, crew medical restraint system, splints, science payload racks, stowage and other equipment racks, science glove box, recreational devices, other portable devices, work surfaces and other workstations, support braces, other secondary structures, etc.&nbsp; This inflatable technology can enable such hardware to be packaged in much smaller volumes for delivery in logistics flights or potentially to be integrated within inflatable spacecraft, increasing trade space options.&nbsp; Crew can also reconfigure spacecraft in-flight, using the ability to 3D-print custom connectors to redesign living spaces or create entirely new interior architectures to respond to mission developments or psychosocial needs.</p> <p>The Habitabiltiy Design Center has already prototyped scale models of inflatable crew stations and initial prototypes of a standard interface connector.&nbsp; These connectors have demonstrated basic capability, but are too large relative to the airbeams for pracitcal use.&nbsp; We have a notional reduced size connector and will use this concept as a starting point, to fabricate and test under operational inflation pressures.&nbsp; Pending initial success, we will fabricate various connectors to provide several linear and angled connections.&nbsp; This will form the basic building block for assembly of a variety of crew stations and support hardware.</p><p>&nbsp;</p><p>This research addresses HAT Needs Numbers 12.1.a and 12.1.b and provides steps towards several HAT-specified performance targets:&nbsp; Bladder Material Selection: The potentially frequent cycles of inflation and deflation experienced by IVA inflatable structures will require bladder material and seal interfaces capable of resisting puncture, tear, flex cracking, or other damage due to folding, handling, or stowage temperatures.&nbsp; Predictive Modeling of Deployment Dynamics: Inflation or deflation may involve imparted torques and loads that require IVA inflatable structures to be anchored to the spacecraft secondary structure prior to the initiation of inflation or deflation.&nbsp; Lightweight Structures and Materials Optimization to Realize Structural System Dry Mass Savings (Minimum of 20-25%) and Operational Cost Savings: The inflatable air beam and connector technology offers significant dry mass savings over traditional IVA structural materials.&nbsp; Structural mass savings for an individual crew quarters is expected to be in excess of 75% over ISS crew quarters.</p><p>&nbsp;</p><p>The intended product deliverable of this activity includes three airbeams of at least 12-inch length and no less than one each of the following: 90-degree connector, 45-degree connector, 180-degree connector, 90-degree five-airbeam connector, 60-degree three-airbeam connector.&nbsp; Additionally, a test report and CAD models for each connector will constitute deliverables of this activity.</p><p>&nbsp;</p><p>Upon completion of this initial ICA effort, we will be able to demonstrate use of the airbeams in conjunction with existing Logistics to Living Modified Cargo Transfer Bags (MCTBs) to demonstrate deployable partitions as an initial example case.&nbsp; This demonistration will be helpful in explaining the potential for continued investment to reduce both mass and habitability risks.&nbsp; We will continue to pursue research funding for further development and will also pursue options to directly engage exploration programs to generate solutions for their specific mission architectures.</p>

Financial Intermediary Funds: Funding Decisions For Gabon

Funding Decisions represent amounts approved by the Financial Intermediary Funds (FIFs) governing bodies for projects fees and administrative budgets. Funding to projects can be done through various financial products, including grants and concessional loans.

Contributions to Financial Intermediary Funds by Germany

The innovative financing and governance arrangements of Financial Intermediary Funds (FIFs) enable funds to be raised from multiple sources, including from sovereign and private sources. FIFs can receive contributions in the form of concessional loans and capital contribution in addition to traditional grant funds. In addition, FIFs can receive funds from innovative sources, such as proceeds from CER sales. This chart shows contributions to all FIFs provided by a country during a certain calendar year.

FY16 Recommended Program Summary

Modular Ultra-High Power Solar Array Architecture, Phase II

Deployable Space Systems (DSS) will focus the proposed Phase 2 SBIR program on the hardware-based development and TRL advance of a highly-modularized and extremely-scalable solar array (Mega-ROSA) that provides immense power level range capability from 100kW to many Megawatts in size. Mega-ROSA will enable extremely high power spacecraft applications, including: Solar Electric Propulsion (SEP) spacecraft, SEP space-tug, and large-scale Planetary and Human Exploration missions because of its ground-breaking stowed packaging efficiency, high deployed stiffness / strength, low-cost and straightforward ground test capability. The innovative and synergistic Mega-ROSA solutions, to be validated to a TRL 6 level during the proposed Phase 2 program, will enable future high power missions through low cost (25-50% cost savings depending on PV and blanket technology), high specific power (>200 W/kg to 400 W/kg BOL at the wing level depending on PV and blanket technology), extremely compact stowage volume (>50 kW/m3 for very large arrays), high deployment reliability, platform simplicity (low parts count and reduced potential failure modes), high deployed strength/stiffness (>5X stiffer and stronger than rigid panel arrays of similar sizes), high voltage capability, scalability to ultra-high power (100kW to several Megawatts), and operability in unique environments (high/low illumination, high/low sun intensity and high radiation).
