Abstract:

The NASA Ames Mission Design Center (MDC) is a multi-disciplinary team that employs concurrent engineering approaches for early-stage mission formulation. Studies are developed using the Concept Maturity Level (CML) framework, an approach like the Technology Readiness Level (TRL) method used to assess technology maturity. We support development of Planetary science, Earth science, Astrophysics, Heliophysics, Technology Development, and Exploration missions throughout the solar system. An overview of our mission formulation approach will be presented followed by a case study to showcase how the CML framework is utilized to mature a Mars mission concept. The CML framework facilitates discussions of concept maturity, provides a basis for improved concept development practices, and helps establish reasonable expectations based on the maturity of the concepts in consideration.

Abstract:

What do launch vehicles, aircraft, reentry capsules, and flight simulations all have in common? They need wind tunnel data to work! The need to test in wind tunnel facilities will not disappear soon, but in order to develop better computational tools (CFD) and design the next stage of rockets and space vehicles alongside aircraft, more advanced experimental techniques are required. At NASA Ames, the unsteady pressure-sensitive paint (uPSP) team has been developing the technology from small-scale benchtop to a useful and innovative system that leverages the Ames Unitary Plan Wind Tunnel and the NASA Advanced Supercomputing Division, also located at Ames, to deliver unprecedented data to customers. Building off advancements in optical access to wind tunnel models, uPSP uses high-speed cameras and high-powered LEDs to fluoresce paint on the model surface to get high spatio-temporal surface pressure data and send it right over to the supercomputer for processing in near-real time. This provides more data faster than traditional pressure transducers can provide and with greater accessibility. It’s not CFD, it’s PSP! 

Biography:

Dr. E. Lara Lash is an aerospace engineering researcher in the Experimental Aero-Physics Branch at NASA Ames. She leads the unsteady pressure-sensitive paint (uPSP) development, which seeks to advance the uPSP technology for new applications and scale the system for use across NASA wind tunnels.

Join online at Teams link: Join the meeting now

Abstract:

When humans spend extended periods in enclosed environments, such as in space stations, lunar habitats, or journeys to Mars and beyond, they require a means to control the environment. For example, products of respiration like carbon dioxide and water, or any trace contaminants from various sources must be removed. Therefore, highly reliable, highly efficient life support systems are essential to maintaining a healthy atmosphere. Several new air revitalization technologies are in development that span the breadth of physico-chemical methods and are unique from heritage systems. The technologies designed, built, and tested by the Air Revitalization Team in the Bioengineering Branch at ARC include utilizing liquid sorbents to capture CO₂ or humidity in microgravity, solid sorbent CO₂ storage and compression, 1-step capture of CO₂ and conversion to water, and cold surface-driven CO₂ capture, purification, and compression. The development of these technologies and their capabilities minimizing mass, power, volume, and spares for spacecraft from low earth orbit to Mars will be discussed.

Biography:

Grace Belancik is the Air Revitalization team lead in the Bioengineering Branch at Ames Research Center at NASA. Her research focuses on environmental control and life support systems, specifically research and development of new technologies for air revitalization to be used in future crewed missions on spacecraft, stations, and surface habitats. Her development projects span the breadth of physico-chemical methods of capturing and managing CO₂ as well as other air constituents including water vapor and trace contaminants. Grace is also on the steering committee of the International Conference on Environmental Systems. She has been at NASA 16 years, and at ARC since 2016. She has a bachelor’s degree in chemical and biomolecular engineering from the Georgia Institute of Technology and is about to have a master’s degree in chemistry from San José State University.

Airspace Integration for US Forest Service

Tuesday, July 15, at 11:00AM Pacific Daylight Time, Syvertson Auditorium N201

Abstract:

In their aviation strategic plan, the US Forest Service (USFS) establishes the goal to “Explore, Evaluate, and Adopt Emerging Technology to Achieve the Aviation Mission More Effectively”.  Researchers in Ames’ Human-Systems Integration Division have been working closely with USFS over the last six years to help progress towards that goal.  At the heart of USFS aviation is communication, coordination, and deconfliction – seemingly simple concepts, but very difficult to execute in the unique operating environments typical of wildland firefighting.  Today’s air tactics, when consisting only of crewed assets are plenty complicated as-is, and while the integration of uncrewed assets brings substantial benefits, sharing airspace between crewed and uncrewed assets can also bring new challenges to the firefighter.  The path to modernization has some challenges, many of which disrupt the human operator’s ability to maintain proper awareness of their task and the various contextual factors they juggle.  Casual conversation will highlight the complexities of decision-making for select areas of USFS aviation, and the research activities conducted to-date that have helped enhance the mission capabilities and airspace integration for USFS aviation.

Biography:

Joey Mercer is a Research Psychologist working in the Airspace Operations Laboratory within the Human-Systems Integration Division at NASA’s Ames Research Center.

Robotic Space Infrastructure

Tuesday, July 22, at 11:00AM Pacific Daylight Time, Syvertson Auditorium N201

Abstract:

Recent advances in mechanical metamaterials offer high-performance structural systems with a modular building block strategy, whereby simple components provide economical scaling. We are also seeing the realization of coordinated multi-agent robotics’ potential to robustly solve complex logistics problems with collections of simple machines. What if these technologies could be combined such that adaptable, reconfigurable structures could evolve through traditional space mission lifecycles from orbital operations to Lunar or Martian surface applications?

The Coded Structures Laboratory at Ames Research Center has demonstrated scalable methods for manufacturing high-performance structures and materials by reversible robotic assembly. This enables scalability and novel system behaviors previously difficult to achieve with conventional methods. This approach was applied to shape morphing aerostructures through the Mission Adaptive Digital Composite Aerostructures (MADCAT) Project, and to space infrastructure through the Automated Reconfigurable Mission Adaptive Digital Assembly (ARMADAS) Project. Recent project activity includes free flight testing of a span-wise twist morphing wing aircraft following successful wind tunnel experiments.
