title: Operations for Autonomous Spacecraft: Downlink Analysis of On-board Decisions and Execution Anomalies

description: Future space exploration missions will heavily rely on autonomous planning and execution (APE) technology to improve spacecraft reliability and reduce operational costs. However, this will require a complete re-vamp of ground operations, i.e., from current practice of specifying pre-planned sequences to specifying high-level goals that will later be elaborated by the onboard APE based on spacecraft’s state and perceived environment. Particularly, determining the mission outcomes during downlink is a challenging task. In this paper, we reconstruct what the spacecraft has executed onboard (i.e., as-executed) using downlinked channelized data, EVRs, and, critically, spacecraft models; We also quantitatively compare as-executed from the “actual” run with ground-based prediction simulations. To do this quantitative comparison, we design an N-dimensional dynamic time warping (DTW) technique based on which we formulate two similarity scores: (a) one related to executed tasks whose cost function is based on interval-based generalized intersection over union; and (b) other related to spacecraft states whose cost function is based on normalized Manhattan distance. Through a simulated case study of multiple flybys in Neptune-Triton system, we demonstrate that our technique successfully quantifies the similarity between the as-executed actual and predicts, and assess its ”in-family” versus ”out-of-family” behavior. To lower the associated false positives/negatives, we also design a multi-objective assessment metric that is a weighted summation of the task and timeline related similarity scores.

title: Improved Cislunar Object Detection Using Polyphase Filter Bank and Polarimetry from Bistatic Radar

description: The exploration and monitoring of cislunar space have gained significant interest, raising the need for advanced radar techniques for object detection and characterization. Previously, the Cislunar Space Debris Radar (CSDR) was demonstrated as a powerful tool for monitoring the presence of objects in the cis-lunar space. This paper introduces innovative signal processing techniques applied to CSDR measurements combining polyphase filter bank (PFB) data processing and polarimetric analysis to enhance object detection in cislunar space. Leveraging the Goldstone Solar System Radar (GSSR) as the transmitter and other Deep Space Station antennas and the Green Bank Telescope (GBT) as the receivers in bistatic radar configuration, the approach demonstrates improved signal processing, reduced noise, and better target discrimination. Results from processing continuous wave (CW) measurements of the Lunar Reconnaissance Orbiter (LRO) and Chandrayaan-2 using this approach highlight enhanced accuracy and potential applications in space surveillance, collision avoidance, and cislunar situational awareness. Additionally, results for one asteroid observation are added to showcase the applicability of PFB to binary phased code (BPC) data, not only CW. This study contributes to radar technology advancement in planetary and asteroid science

title: Influence Diagrams for Optimal Decision Making in Early Science Space Mission Concept Development

description: Concept design maturation is an initial phase in theengineering design process that revolves around decisionmaking. In the context of science space mission conceptdevelopment, decision trees play a crucial role. The branches indecision trees are interdependent, meaning that the probabilityof future outcomes depends on past decisions. However, thereare limited resources available for exploring these differenttrade space options, such as time, money, and workforce.Therefore, the main challenge is to efficiently conduct this tradespace exploration and generate a wide range of mission ideasand alternatives from which new programs/projects can beselected. This is the purpose of the NASA Pre-Phase A projectlife cycle phase.To better understand the concept of decision trees, it'simportant to clarify certain terms. A decision tree is a specifictype of graph, which is a collection of objects where some objectshave relationships with each other. In a directed graph, theseobjects are called vertices and are connected by directed edgesor arcs. A directed acyclic graph (DAG) is a directed graph thatcontains no cycles, meaning there are no loops formed whenfollowing the directions of the edges.One approach to reaching optimal decisions is by employing aninfluence diagram. An influence diagram (ID) is a concisegraphical and mathematical representation of a decisionscenario. By utilizing the structure of a directed acyclic graph,influence diagrams provide a visual and intuitive way torepresent the relationships between variables, decisions, andoutcomes, facilitating analysis and decision-making underuncertainty. Influence diagrams are particularly useful formodeling decision problems that involve uncertainty andcomplex dependencies. They can represent decision problemsinvolving multiple decision-makers, allowing for a morecomprehensive analysis of interactions and dependenciesbetween different decision-makers. Influence diagrams can alsohandle decision problems with multiple objectives, enablingdecision-makers to consider trade-offs between differentcriteria and incorporate subjective preferences. Influencediagrams extend the concept of a Bayesian network and allowfor modeling and solving both probabilistic inference problemsand decision-making problems based on the maximum expectedutility criterion.This paper will explore the development of influence diagramsand their application in science space mission conceptdevelopment at the Jet Propulsion Laboratory.

title: DEVELOPMENT OF HIGH POWER LITHIUM MAGNETOPLASMADYNAMIC THRUSTERS FOR HUMAN MARS MISSIONS

description: Potential future missions supporting human Mars exploration require major advances in space transportation infrastructure. Hybrid systems of nuclear electric and chemical propulsion are one option under study as part of NASA’s Moon to Mars initiative. To mature relevant technologies and provide data to support mission architecture studies, the Space Nuclear Propulsion project has recently started the development of high power lithium-fed magnetoplasmadynamic thrusters, a potential option for nuclear electric propulsion. These electromagnetic accelerators offer very high power density and high performance, having demonstrated over 60% efficiency at specific impulses over 4000 s and power levels of 500 kWe to 1MWe. Initial work is focused on building a 100-200 kWe-class thruster and shaking down an existing facility which can accommodate thrusters with power levels up to 2 MWe. Subsequent development would address the remaining technical challenges, including achieving required thruster life, at power levels of 500 kWe to 1 MWe.

title: Surface Timeline Management and Analysis for the Mars Sample Return Mission

description: The Mars Sample Return Campaign being planned jointly by the U.S. National Aeronautics and Space Administration and the European Space Agency seeks to return samples of Martian rocks and atmosphere from the surface of Mars to Earth for subsequent scientific analysis. It is comprised of two flight projects, which would retrieve the samples acquired by NASA’s Mars 2020 Perseverance rover and return them to Earth. One of the flight projects would be the Sample Retrieval Lander, led by NASA, which would land on the surface of Mars, collect the samples from Mars 2020, and launch them into Mars orbit. The second flight project, led by the European Space Agency, would be the Earth Return Orbiter, which would capture the samples and return them to Earth.The baseline Sample Retrieval Lander surface mission nominally extends from landing on October 17, 2030 to the end of the Mars launch period on May 27, 2031, which yields a total surface mission duration of 222 Earth days, or 215 Mars Sols. In the most constrained timeline, the Sample Retrieval Lander could land as late as November 11, 2030, reducing the total surface mission duration to 197 Earth days, or 190 Mars sols. The limited time to perform the Sample Retrieval Lander surface mission is a critical constraint on the surface phase and drives many aspects of flight system and mission system design. Unlike previous Mars missions, there is no possibility of extended mission time on the surface, due to the Earth return launch constraint. It is therefore imperative to manage the Sample Retrieval Lander surface timeline as a critical project resource. This paper will present an overview of management practices and analytical methodologies developed by the Sample Retrieval Lander surface team to ensure mission objectives are met within the available surface mission timeline. The nominal surface timeline is built from the bottom up, starting with the basic duration constrained by activity duration, energy consumption, and ground in the loop decisions. Growth factors and developmental margin are added to the basic duration to yield the maximum growth timeline duration. This maximum growth timeline duration plus the desired operational margin is compared against the available mission duration of 190 sols to assess the health of the surface timeline. A suite of products has been developed to capture the robustness of the surface timeline, conduct probabilistic analysis of the timeline, and provide regular reporting on the health of the timeline with data visualizations to inform technical and operational design decisions. The timeline analysis and management practices outlined in this paper aim to serve as a resource for future time-constrained aerospace missions and applications. The decision to implement Mars Sample Return will not be finalized until NASA’s completion of the National Environmental Policy Act (NEPA) process. This document is being made available for information purposes only.

title: Investigation of Clutter Removal on Cis-Lunar Target Detection Using DSN Open-Loop Tracking Data

description: As NASA and other space agencies are gearing up toreturn to the moon, there is significant interest andopportunities in detecting and tracking small objects in cislunarspace. NASA’s Jet Propulsion Laboratory (JPL) initiatesa strategic plan to develop detecting and monitoring techniquesusing NASA’s Deep Space Network (DSN) tracking stations andthe Goldstone Solar System Radar (GSSR) This papersummarizes the work and preliminary results of detecting Cislunarobjects in four radar experiments in 2022 - 2023 using themeasurements collected with Open-Loop Receivers (OLRs) ofthe Deep Space Network Goldstone complex. The research aimsto evaluate the feasibility of using the GSSR with OLRconfiguration to detect objects in the cis-lunar environment,especially investigating the background clutter impact on thenear-moon object tracking. Due to its practical implementation,the time-frequency domain analysis, such as the Short TimeFourier Transform (STFT) or wavelet we demonstrated in thispaper, could be a powerful tool in real-time patternclassification for distinguishing between a target’s echoes andlunar clutter interferences. We evaluate the OLR’s cis-lunarobject tracking performance using the data collected from thefour experiments. We also assess the performance of Cis-lunartarget detection by comparing observations with the Dopplerfrequency estimates derived from the spacecraft’s orbitaldynamics, lunar noise temperature impacts, background cluttereffects, and Signal-to-Noise Ratio simulations. These researchfindings will improve our engineering knowledge and technicalconstraints for future detection and tracking of cis-lunartargets, including satellites,

title: Creating the James Webb Space Telescope’s first color images

description: The first color images from the James Webb Space Telescope (JWST, Gardner et al. 2023) were designed with the understanding that a NASA/ESA/CSA flagship must explain its purpose and science to the taxpaying public, and that to earn the opportunity to explain and educate, we must first inspire. The feeling that many people have when seeing a well-composed color image of a deep space scene for the first Lme is visceral. It connects to a deeper part of the psyche than that of pure reason, like the effect of music or other visual arts. It is in eliciLng this emoLon that we have an opportunity to draw people in and educate; inevitably quesLons follow: What do I see? What do the colors and shapes mean? How large, distant, or old is this? And how does it relate to us, the Earth, the Sun, and my environment? It is in answering these quesLons we can educate, encourage children to take up careers in STEM, and hopefully convince the public that science is a fundamental human endeavor.
