title: Forcing of subannual-to-decadal sea level variability and the recent rapid rise along the U.S. Gulf Coast

description: From the mid-late 2000s through at least the mid-2010s, dynamic sea level (DSL) along the U.S. Gulf Coast rose at a rate of ~5-7 mm/yr, almost twice the rate of global mean steric plus barystatic sea level rise. Previous statistical and numerical modeling studies have suggested a number of hypotheses for this enhanced rise. However, the atmospheric and hydrologic forcing contributions to this enhanced rise have not been quantified. This study quantifies forcing contributions to DSL using adjoint sensitivities from the observationally-constrained Estimating the Circulation and Climate of the Ocean (ECCO) state estimation framework. Convolving the adjoint sensitivities with air-sea fluxes from the ECCO state estimate and JRA55-do river discharge shows that Gulf Coast DSL at subannual and interannual timescales is mostly driven by wind stress along the Gulf and U.S. Atlantic coasts, consistent with the propagation of coastal Kelvin and topographic Rossby waves. In contrast, the decadal-timescale enhanced rise in DSL can be attributed to trends in wind stress and heat fluxes across the North Atlantic, from the Caribbean to the subpolar latitudes. A decline in Mississippi river discharge during this period produced a ~1 mm/yr decrease in western Gulf Coast DSL, tempering the rapid rise in the down-waveguide direction from the Mississippi outflow. Reconstructions of the decadal Gulf Coast DSL using ERA5 atmospheric reanalysis were not as successful at reproducing the timing of the rapid rise, suggesting the importance of dynamically-consistent ocean data assimilation in constraining estimates of decadal-timescale air-sea flux variations.

title: JGR Planets paper: Assessing the plausibility of past cryovolcanism on 2 Umbriel using the Wunda impact crater

description: The imaged portion of Umbriel’s surface is dark and cratered, suggesting limited geologic activity. However, bright deposits occupying the Wunda impact crater may be of endogenic origin, similar to proposed cryovolcanic sources for fresh bright material occupying Occator crater on Ceres. Here, we model the formation of Wunda using iSALE-2D. Our goal is to determine whether Wunda’s inferred morphology is consistent with the interior structure predicted for Umbriel and whether Wunda’s interior might originate from impact-induced cryovolcanism and/or was sourced from a subsurface ocean. We find that, if Wunda is indeed a complex crater, as coarsely resolved imagery suggests, Umbriel’s ice shell may have been much thinner (≤ 50 km) and/or warmer (≥ 240 K) than predicted at present or subject to significant structural/ compositional differences, such as abundant volatiles. These results help assess the thermal evolution of the Uranian satellites as potential ocean worlds.

title: Progress on the Implementation of a First-Principles Model of the Anomalous Momentum and Heat-Transfer in Hall2De

description: Building on plasma instability theory, we previously developed a first principles model for the electron momentum transfer in Hall thrusters in which short-wavelength electron cyclotron drift instability modes saturate at low turbulence levels while longer-wavelength lower hybrid modes grow to provide the observed anomalous electron momentum exchange, yielding a closed-form expression for the momentum and heat transfer collision frequencies in terms of local plasma variables. In this article we report on the implementation status of this model in Hall thruster simulations. We find that when the model is employed in simulations that make use of the generalized Ohm’s law, the axial electron current density becomes a function of the electron temperature primarily, making the determination of the plasma potential from current conservation numerically difficult. We propose that a coupled approach in which the electron temperature, current conservation, and generalized Ohm’s law equations are solved together may improve the numerical stability of the method. In a parallel effort, motivated by recent promising results from fellow researchers at SPARC Industries who achieved stable simulations using our closed-form model in a 2½-D axial-radial fully kinetic Particle-in-Cell (PIC) code, we have developed a 1-D full electron momentum solver that accounts for electron inertia. This code has been verified against simulations that make use of the generalized Ohm’s law. Although computationally intensive and, therefore, impractical for engineering applications, we plan to use this code to better understand the 2½-D PIC simulations and to learn how we might be able to achieve stable numerical simulations with our anomalous momentum-transfer model in engineering codes like Hall2De.

title: Flexible Trajectory Planning with the Dyna Reinforcement Learning Architecture Under Computation Constraints

description: Spacecraft autonomy is increasingly critical for missions involving long communication delays, spacecraft fleets, or fault-prone actuators. Prior work demonstrated that Dyna-style reinforcement learning (RL) architectures, which combine model-based planning with model-free updates, can adapt to actuator degradation and changing dynamics. However, these implementations assumed fixed computational availability, limiting robustness under dynamic processor loads. This work extends the prior Dyna framework by incorporating time- and processor-aware planning, dynamic batching of critic updates, and improved activation functions to mitigate neuron inactivation. Hardware experiments on a planar air-bearing platform and large-scale simulations demonstrate that the modified architecture reduces control cost, lowers failure probability under thruster degradation, and decouples performance from processor speed. These results highlight the importance of integrating computational awareness into RL-based controllers and provide a practical methodology for improving the resilience and adaptability of spacecraft guidance, navigation, and control systems.

title: Hazard Detection Flight Software for Processing LIDAR Generated DEM

description: Hazard Detection (HD) is an enabling technology for safe landing on planetary bodies when the lander hazard tolerance capability is at the resolution limit of orbital imagery. This situation is common to many planetary bodies in the Solar System including Moon and Mars. At these locations, an autonomous lander can utilize a Light Detection and Ranging (LIDAR) sensor to map the landing area and construct a Digital Elevation Map (DEM) in real-time. The HD software developed by the Safe and Precise Landing Integrated Capabilities Evolution (SPLICE) project is designed to process a DEM and identify safe landing locations in real-time. The hazard detection method is applicable to 4-legged lander geometry and is adaptable to different hazard tolerance and run time requirements. This paper discusses the hazard detection performance of the SPLICE HD software using DEMs generated by the SPLICE Hazard Detection LIDAR.

title: SimulatingLunar Conditions for Autonomous Power and Thermal Management in theEndurance Rover

description: The proposed Endurance lunar rover mission introduces autonomous, long-duration exploration in the challenging operating environment of the lunar South Pole–Aitken Basin. This paper adds autonomous power and thermal management to the existing autonomy capabilities on the Endurance project. This upgrade represents a step-change that enables the rover to reason about its onboard resources for the first time. The proposed testing architecture supports meaningful Earth-based field testing by coupling real hardware with simulation-inthe- loop models that capture extreme lunar thermal conditions and mission-relevant power behavior. This setup allows Endurance’s autonomy software to run closed-loop using native signals where possible, while substituting simulated lunar counterparts to expose behaviors that cannot be tested otherwise. Through extensive physical and simulated testing, covering more than 4 km of continuous driving, we show that the system can manage its internal state and resources autonomously under lunar-representative conditions, validating system-level autonomy performance. Finally, we provide a matrix of testing configurations that span different simulation fidelities and hardware integrations to support ongoing mission development.

title: Performance of the Psyche Electric Propulsion System during the First Cruise Phase

description: Psyche is the first mission to use Hall thrusters in interplanetary space. The first phase of cruise thrusting operations began in April 2024 and ended in September 2025, with almost 8,000 hours of operation and 5.4 MN-s of impulse provided to date. Here we review the operation and performance of the electric propulsion subsystem over that period. Thruster electrical telemetry have been nominal and within expectations. Thrust reconstructions for three of the thrusters have been within 2% of pre-launch expectations, with Thruster B overperforming due to an out-of-family behavior identified prior to cruise operations. Thruster A has the most operating time of all thrusters, and comparison of the in-space performance to that of the ground-based life test over similar time periods shows that although both decrease to 92% of the original thrust, the in-space thrust did so suddenly compared to the gradual decrease in the life test. Thruster swirl torque has been measured regularly for all thrusters during the cruise phase, and we show that the Thruster A swirl torque near the 3.8-kW power level was unchanged after 2,800 hours of operation. Finally, we describe a significant fault that occurred in the propellant feed system during the cruise phase, how it was diagnosed, and the continuation of the mission using redundant hardware.

title: Designing Planetary Missions for Uncertain Environments: Lessons Learned and Path Forward

description: Unknowns in the science environment have shaped many planetary science missions, with outcomes ranging from significant scientific discoveries to partial or complete loss of mission objectives. The magnitude of these effects depends on the mission context, including the scientific scope, the degree of operational flexibility, how environmental uncertainty is addressed during formulation, and how the mission responds to unexpected conditions in flight. This paper examines several planetary science missions that encountered environments or physical processes that differed from expectations to identify factors that influence adaptability in the concept of operations. The missions considered are Pioneer, Galileo, Cassini, New Horizons, Dawn, OSIRIS-REx, and Europa Clipper. A cross-mission analysis compares the unexpected conditions encountered, the strategies used to account for uncertainty before launch, the in-flight responses, and the resulting impacts. Insights from these case studies support a framework for evaluating the adaptability potential of a mission’s concept of operations. Four design pillars, flexibility, observability, responsiveness, and commitment, are identified, from which design principles are derived, offering guidance for designing planetary missions that can adapt effectively to unexpected environments.

title: Earth to Mars: Developing Requirements for an Earth Orbiting Perimeter Truss Reflector for the Mars Environment

description: NASA’s “Expanding the Horizons of Mars Science” report emphasizes the need for low-cost, smaller satellites for future Mars missions, accompanied by enhanced Mars-Earth telecommunications. Current Mars telecom relay orbiters cost $400M–$800M (adjusted for inflation), with rising costs outpacing budgets. Leveraging deployable antennas, such as Tendeg’s perimeter truss reflector (PTR), could enable small spacecraft (&lt;500 kg) to match the capabilities of larger relays at a fraction of the cost (&gt;$100M per spacecraft). To reuse a 3-meter GEO PTR for Mars, it is important to develop the requirements for the Martian application of the antenna, and understand what differences exist between GEO and Mars. Key requirements include packaging and spacecraft interface, optical prescription and geometric accuracy, and environmental. Environmental requirements include those related to vibration, radiation, thermal and aerobraking. Future work will validate the PTR design against Mars-specific requirements defined here, focusing on cold-temperature performance.
