Artificial Intelligence: Powering Human Spaceflight Exploration of the Moon and Mars

Abstract:
The NASA Autonomous Systems and Operations (ASO) project has developed and demonstrated numerous autonomy enabling technologies employing Artificial Intelligence (AI) techniques. Our work has employed AI in three distinct ways to enable autonomous mission operations capabilities. Crew Autonomy gives astronauts tools to operate space vehicles or systems without assistance from Mission Control. Vehicle System Management uses AI techniques to turn the astronaut’s spacecraft into a robot, allowing it to operate when astronauts are not present, or to reduce astronaut workload. AI technology also enables Autonomous Robots to act as crew assistants or proxies when the crew are not present. In this seminar, we first describe human spaceflight mission operations functions, and classify these functions as monitoring, planning, plan execution, and fault management. We describe the wide range of development and demonstration activities performed by ASO since 2011. We describe the AI techniques behind each of these demonstrations, which include a variety of symbolic automated reasoning and machine learning based approaches. Finally, we conclude with an assessment of these demonstrations, motivating future development needs for AI to enable NASA’s future Exploration missions.

Future of Space Biology and Biomedical Advancements for Deep Space Exploration

Abstract:
As humans venture beyond low earth orbit into deep space, they will need to embark on lengthy and prolonged missions. To make this possible, space biology research is being conducted to understand the effects of space environments on living organisms. Computational and modeling approaches are being used to deepen the biological understanding of spaceflight and facilitate predictive modeling and analytics. Multi-modal NASA space biology data have been used to model the effects of spaceflight on mammalian muscle physiology, resulting in the identification of novel molecular targets and networks to advance our understanding of muscle atrophy during space travel. Large predictive models are designed to incorporate terrestrial biomedical knowledge bases to enhance space biological predictions. Standardized training datasets have been created from public NASA data and made available in cloud-based repositories. In this emerging field, computational and modeling approaches can support automated and reproducible experiments and efficiently manage spaceborne data and metadata to support NASA’s goals of open science. Strategic funding is necessary to develop automated, light, agile, and intelligent terrestrial capabilities to accelerate biological experimental platforms, spacecraft ecosystems, habitats, and health support systems. Humanity can thrive in deep space by integrating biomonitoring approaches, biomarker science, spacecraft and habitat hardware, intelligent software, and streamlined data management tools.

Digital Materials: In-Space Assembly for Space Infrastructure

Abstract:
NASA’s envisions a sustained and thriving cislunar economy that can fuel not only technological and scientific advances, but also propel humanity to Mars and beyond. However, sustained human presence and industry requires infrastructure—roads, shelters, communication towers, power, orbiting stations, and more. The challenges of the supply chain from Earth, communication blackouts/delays, and the extreme environment require unique solutions that prioritize re-usability, versatility, autonomy, and repairability. To address these needs, NASA Ames is leading an effort to extend the concept of programmable matter, material that can autonomously adapt to any need or environment, to high-performance space systems. The system is based on the concept of discrete or ‘digital’ materials which are assembled from a small number of unique building block types, combined to achieve diverse functionality. To provide programmability, adaptability, and scalability, these materials are assembled and reconfigure autonomously by robots that locomote in and on the structures. Together, the robots and discrete structure form a versatile, scalable, and fully autonomous infrastructure system that can meet future space needs.

NASA’s Use of Supercomputing in the Artemis Program

Abstract:
NASA has one of the world’s largest supercomputing centers, located right here at NASA Ames, and one of the world’s most exciting programs in the Artemis program. How is supercomputing used in support of Artemis at NASA? How does that compare to the Apollo program? Is computational modeling really necessary for exploration if NASA did something similar in the 1960s? These questions are fun but certainly too hard to answer in one seminar! Nonetheless, Derek will share some of the ways that NASA groups use computational modeling to support Orion, Space Launch System, and Exploration Ground Systems. While most of an Artemis mission is spent in space, the beginning and end include a rapid traverse of Earth’s atmosphere. The aerodynamics, heating, and acoustics of these ascent and descent phases are the primary focus of Artemis-related supercomputing. These environments are difficult to model, challenging to test, and it takes many groups at multiple NASA centers to understand them sufficiently for flight. Listen in and enjoy some highlights from around the agency about high-performance computing affecting NASA space exploration.

Chasing Shadows in the Night: How NASA’s Kepler and TESS Missions Are Revolutionizing Exoplanet Science

Abstract:
The first planet orbiting a Sun-like star outside our solar system was discovered ~28 years ago. Since then, we’ve detected over 5445 planets and 75% of these have been detected by transit surveys. The Kepler Mission, launched in 2009, has found the lion’s share (>3326), and demonstrated that each star in the night sky has, on average, at least one planet. However, many questions remain: How do these planets form and evolve? What are the structure and composition of the atmospheres and interiors of these planets? Can we detect biomarkers in the atmospheres of these planets? The Transiting Exoplanet Survey Satellite (TESS) launched in 2018 to conduct a nearly all-sky survey for transiting planets. TESS has identified 350 so far, of which 108 are <4 REarth and have measured masses, providing the first clues to their composition. Many of these can be further studied by large telescopes such as the Webb Space Telescope. In this talk I will describe how we detect weak transit signatures in noisy transit survey data sets and present some of the most compelling discoveries made so far by Kepler and TESS.

Future Arctic (Wild)Fires

Abstract:
Wildland fires in the boreal and Arctic are increasing in frequency and severity, with extreme fire seasons documented across the Pan-Arctic and boreal in five of the last seven years. Human-caused and wildland fires above 60°N were larger sources of black carbon and methane than current modeled estimates of anthropogenic sectors like energy extraction and transportation. Further, these large boreal and Arctic fires have the potential to release large amounts of carbon dioxide and subsequent methane emissions from degraded permafrost and peat fires, as well as negatively impacting air quality thousands of miles south. By end of this century, current extreme fire years in the Arctic will likely be a normal fire year for much of Greenland, North America, Northern Europe, and Eurasia. As a new horizon in global wildland fire science, novel scientific pathways must be undertaken to improve our understanding and management of wildfires in the High Northern Latitudes – including understanding how NASA can enhance collaboration and develop near-real-time fire monitoring and modeling between North American and European ecology, fire, and climate scientists and stakeholders. Issues of inclusion, diversity, and equity are inherent to understanding fire ecology, impacts, and management in the Arctic and boreal, including centering and deferring to Indigenous and local communities when constructing best management practices.

Beyond BioSentinel: Iterative Development of Automated Microfluidics

Abstract:
NASA Ames has flown a series of Bio-CubeSats that performed biology experiments supported by automated fluidic systems. Since Genesat-1 in 2006, these payloads have increased in complexity and functionality, building upon previous successes, and applying lessons learned. BioSentinel was the most recent of this series, launched into heliocentric orbit onboard Artemis-1 in 2022. This presentation will discuss how the fluidic technology developed for these Bio-CubeSat missions, including the multi-layer polycarbonate manifolds at the heart of the BioSentinel BioSensor, have spurred the development of several additional projects. Most directly is the modified BioSensor that will be a part of LEIA, which will perform its Lunar biology experiment onboard a Commercial Lunar Payload Services lander. Several search-for-life manifolds have been designed to prepare samples from icy moons for downstream analyses. Two early career Polaris projects are developing fluidics to perform genetic sequencing on samples from multigenerational cell culture and to extract and quantify target miRNAs to support astronaut radiation health assessment. Improving the readiness of these systems has been accelerated by adopting the established flight heritage and microgravity-compatibility of the Bio-CubeSat fluidic hardware and designs, while focusing development efforts on the integration of novel functionalities and components.

Biography:
Dr. Padgen received his M.S. and Ph.D. in Nanoscale Engineering from the University at Albany, SUNY, for his work on biomedical sensors, microfluidics, and development of an implantable device used to study the tumor microenvironment. He joined NASA Ames in 2014 as a member of the EcAMSat (E. Coli Anti-Microbial Satellite) team, helping to resolve leak and filling issues in the fluidic card. In 2017, he assembled the flight payload that successfully operated in low Earth orbit. He joined BioSentinel in 2015 to support the testing and development of the BioSensor fluidic system, and in 2019-20 assembled the ISS and free-flyer flight and ground control payloads. Since 2021, he has been a part of LEIA, which is incorporating lessons learned from BioSentinel to improve the design of the BioSensor to run experiments on the Lunar surface. In addition to these flight projects, he has led the fluidic development on early-stage projects, including ChIPPS (Charged Information-storage Polymer Preparation System), SAMMS (Spaceflight Autonomous Multigenerational Microbial Sequencer), and RADREADS (Radiation Assessment DuRing Exposure And long-Duration Spaceflight).

Pale Purple Dot: The Search for Life on Exoplanets

Abstract:
The remote detection of signs of life beyond our solar system is fast becoming a reality, and astrobiology goals have in part driven the design of the astrophysics flagship missions in the “Pathways to Discovery in Astronomy and Astrophysics for the 2020s” decadal survey. While different exoplanet astrobiology science cases were considered in the mission concept studies, there still exists a high need for precursor science that will help inform mission designs and trades. Ames’ Space Science and Astrobiology Division is uniquely well positioned to contribute to the Great Observatories Maturation Program (GOMAP) due to its synergistic expertise in astronomy, planetary science, and astrobiology. In particular, opportunities exist to incorporate astrobiology throughout the mission cycle and to infuse knowledge from different chemical and biological disciplines into the precursor science activities. A tour will be given of traditional exoplanet biosignatures such as oxygen and methane, as well as underconsidered, novel, agnostic, and photosynthetic pigment surface biosignatures (pale purple dot). A framework for integrating lessons learned from the planetary science in situ biosignature community will also be provided. Considering a broader range of science cases at this early stage in mission design would enable the development a more capable observatory for exoplanet life detection.
