title: Robust Replanning for Multi-Agent SmallSat Inspection in Failure Scenarios

description: Future space structures like the proposed Lunar Gateway will require autonomous inspection and maintenance, especially during extended uncrewed periods. Small satellites (SmallSats) offer a low-cost alternative to human extravehicular activities (EVAs) for performing these tasks. However, SmallSats have a high failure rate, particularly with propulsion systems, often causing mission failures. This work is motivated by this failure rate and considers a multi-agent approach to SmallSat inspection as a way of increasing mission success through redundancy. The added risk of the multi-agent approach, namely collision risk during thruster or other system failures, is addressed. We propose a collision-aware path-planning strategy based on the Anytime Dynamic A* (AD*) algorithm, enabling efficient initial path generation and dynamic replanning in response to failures. Implementation considerations like collision-checking in a high-fidelity simulation environment are discussed. The proposed strategy is demonstrated in a case study multi-agent inspection scenario around simulated Lunar Gateway geometry, where one SmallSat experiences a thruster failure, prompting other agents to replan their paths.

title: Denoising Diffusion Probabilistic Model for realistic and fast generated Euclid-like data for weak lensing analysis

description: Understanding and mitigating measurement systematics in weak lensing (WL) analysis requires large data sets of realistic galaxies with diverse morphologies and colors. Missions like Euclid, the Nancy Roman Space Telescope, and Vera C. Rubin Observatory’s Legacy Survey of Space and Time will provide unprecedented statistical power and control over systematic uncertainties. Achieving the stringent shear measurement requirement of |m| &lt; 10−3 demands analyzing 109 galaxies. Accurately modeling galaxy morphology is crucial, as it is shaped by complex astrophysical processes that are not yet fully understood. Subtle deviations in shape and structural parameters can introduce biases in shear calibration. The interplay between bulges, disks, star formation, and mergers contributes to morphological diversity, requiring simulations that faithfully reproduce these features to avoid systematics in shear measurements. Generating such a large and realistic data set efficiently is feasible using advanced generative models like denoising diffusion probabilistic models. In this work, we extend Hubble Space Telescope (HST) data across Euclid’s broad optical band using the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey and develop a generative AI tool to produce realistic Euclid-like galaxies while preserving morphological details. We validate our tool through visual inspection and quantitative analysis of galaxy parameters, demonstrating its capability to simulate realistic Euclid galaxy images, which will address WL challenges and enhance calibration for current and future cosmological missions.

title: On the Size of the Mission Suite Enabled by NASA's Deep Space Network

description: The Deep Space Network (DSN) is the primary means of commanding, tracking, and receiving data from all of NASA's deep space missions, as well as a number of deep space missions operated by other international space agencies. The current number of missions enabled by the DSN is approximately 40 missions, but there has been concern about the level of "over-subscription" of the DSN, namely that the number of missions currently using the DSN is larger than can be enabled reasonably. This manuscript assesses the maximum number of missions that could be enabled, based on recent performance and with the constraint that the total number of hours used per week does not exceed the available number of DSN antenna-hours. Three different models considered, and the maximal number of missions that could be enabled ranges between approximately 40 missions and 70 missions, assuming that there continues to be approximately six Mars missions and that those Mars missions continue to make use of the DSN's multiple spacecraft per antenna (MSPA) capability. Crucially, the conclusion that an approximately 50% growth in the DSN mission suite rests on the assumption that the DSN antennas are "interchangeable," but they are not, with some spacecraft able to use only certain antennas. Efforts to make the DSN antennas more "interchangeable"' primarily in their transmitter and receiver suites, would be an effective means of ensuring expanded capability. Additional findings from this work are that, while additional use of the MSPA capability might appear to be a promising means for increasing the mission suite, there appear to be no locations in the Solar System, other than Mars, for which it would be effective.

title: Demonstration of the Dyna Reinforcement Learning Framework for Reactive Close Proximity Operations

description: Lessons from the International Space Station (ISS) emphasize the necessity of exterior inspection for anomaly detection and maintenance, but current methods rely on costly and limited human extravehicular activities and robotic arms. Deployable free-flying small spacecraft offer a flexible, autonomous solution, capable of comprehensive exterior inspections without human involvement. However, the safety of these spacecraft during close proximity operations remains a concern, particularly given the variability in thruster performance. This paper presents SmallSat Steward, a reactive and integrated architecture for online model learning and trajectory planning based on the Dyna reinforcement learning architecture. By combining model-based planning and direct reinforcement learning, Dyna offers a flexible and computationally-efficient solution capable of adapting to changes in thruster performance and other system uncertainties. Preliminary results in both simulation and hardware environments demonstrate the potential of this architecture to successfully regulate position under significant model degradation

title: Deep Space Network Support of the Intuitive Machines Lunar Lander

description: NASA’s Deep Space Network (DSN) has been designed for the past six decades with very large antennas and customized technologies to communicate with distant planetary missions, including spacecraft outside the solar system. The current exploration trend has shifted emphasis to supporting missions in cis-lunar space and at Lagrange points. This has led to modified strategies for more dynamic mission events and faster planning cycles than traditional solar system missions. In addition to the committed support of many missions, the DSN is a national asset that has supported missions in unplanned scenarios. The historic Intuitive Machines (IM) lunar mission, Odysseus, landed at Malapert A crater near the south pole on 22 February 2024. Prior to launch, there were no plans to utilize the DSN but the spacecraft conditions in transit, in lunar orbit, and after landing necessitated the use of large antennas capable of receiving low signal-to-noise downlink and transmitting high power uplink signals for the purpose of telemetry, commanding, and navigation. A DSN team responded to the request and collaborated with the ground station at Morehead State University (MSU) to relay commands between the IM Nova Control Center and the DSN’s central facility, made possible because MSU had established interfaces with both partners prior to launch while the DSN did not have a Space Link Extension (SLE) interface in place. The infrastructure of the Lunar Node 1 payload carried by Odysseus, which was planned to be tracked by the DSN, played a key role in facilitating this support. This paper describes the complex multi-partner communications architecture that enabled Odysseus’ successful mission and details the concept of operations using stations across multiple continents to achieve reliable two-way communications. The paper also describes the multipath effects that disrupted communications pervasively during surface operations and show how the point of reflection in the lunar surface was reconstructed after-the-fact using data collected during the mission.

title: Federated Autonomous Operation: A New Paradigm for Large-Scale Observation Systems

description: Coordinated observation systems can provide new insights and measurements of phenomena on Earth and in space. The number of spacecraft available for observation has grown rapidly in the last few years, opening the door for larger and larger observation systems. However, the vast suite of observing assets available for observation are not operated by a single omnipotent entity. Instead, fleets of assets have different operators. We envision a federated observation system composed of many operating entities. A federated observation system can leverage all observing assets across operators for timely and coordinated measurement. A federated system requires novel federated autonomous operations to address the distributed control of the system. This work discusses federated scheduling, an approach to coordinating the observing assets across a federated observing system. Federated scheduling enables (1) the use of all available assets for observation, (2) distributed tasking of the system, and (3) resolving contention among competing campaign objectives. We discuss large federated autonomous systems including how they would be operated, the underlying artificial intelligence that autonomously coordinates entities and assets, and the novel capabilities that are enabled by such an observing system.
