title: Improving tropical cyclone rapid intensification forecasts with satellite measurements of sea surface salinity and calibrated machine learning

description: Forecasting rapid intensification (RI) of tropical cyclones (TC) is a mission known for large errors. One under-researched factor that affects TC intensification is sea surface salinity (SSS), which is an important proxy for density stratification in certain ocean regions and can affect the surface enthalpy flux under a strengthening hurricane. To investigate the effects of SSS on TC RI, we use a previously built statistical model consisting of a variety of machine learning (ML) methods. A calibrator was trained on top of the ML models to correct probability forecasts. The ML model performance is improved with the addition of SSS in the Eastern North Pacific and the Caribbean subregion of the North Atlantic. Limited improvement is found in the Western North Pacific. In the Indian Ocean, SSS is also notably correlated with RI occurrence, but the TC samples are not sufficient to train ML models.

title: Spherical Bessel Harmonic Gravity Expansions and Their Properties Related to Sir Isaac Newton's Shell Theorem via the Riemann Zeta Function

description: The conventional spherical harmonics used to describe the gravity field surrounding a non-spherical mass only converge exterior to the body’s Brillouin (circumscribing) sphere. The complementary gravity field interior to this sphere is provided by spherical Bessel harmonics. We present an algorithm for calculating the Bessel harmonic coefficients directly from the surface integral of an arbitrary shape with homogenous density. Exploring the special case of a homogenous sphere, we show that the Bessel harmonic expansion is a generalization of Newton's Shell theorem. In this special case, the non-zero Bessel coefficients are shown to be related to the Riemann zeta function.

title: Maneuver Design Techniques for Deploying and Maintaining the SunRISE Constellation

description: The Sun Radio Interferometer Space Experiment (SunRISE) mission will employ a constellation of 6 CubeSats in an orbit 300 km above geostationary to study the transport and acceleration of solar energetic particles associated with coronal mass ejections. While the spacecraft are capable of executing maneuvers anywhere within the orbit, selecting the time of the OTM may minimize the DeltaV, ensure that DeltaV constraints are met, and minimize the chance of close approaches within the constellation during transfers. The present paper focuses on the maneuver design process for deploying and maintaining the constellation in a loose, repeating formation to create the first spaceborne imaging interferometer.

title: Psyche's Thruster Checkouts: Design, Navigation Strategy, and Results

description: Psyche, a low-thrust solar electric propulsion spacecraft, is currently on its way to the main- belt asteroid (16) Psyche. The sole source of propulsion is a set of four Hall effect thrusters, a technology which had never flown beyond cislunar space prior to this mission. In order to ac- curately design thrust maneuvers and predict the trajectory of the spacecraft while thrusting, the thrusters needed to be characterized and calibrated during the initial checkout phase. We detail here the design of these calibration activities, the navigation strategy and filter setup for estimating the actual thrust, and the results obtained for the Psyche mission.

title: Extending Coverage Modeling to Voter Behavior for Spacecraft Reliability Modeling

description: Embedded computer-based systems, or digital systems, are used in applications, such as spacecraft, which require high reliability. Meeting the reliability requirements at the lowest possible cost, typically involves trade studies that aim to quantify the value of different mechanisms for obtaining high reliability. One of these mechanisms is fault tolerance, which involves the detection, location, isolation, and recovery of the system upon occurrence of a fault. The coverage parameter has been defined as the likelihood of successfully recovering from a fault that has occurred. If the fault and error handling mechanisms cannot successfully cover all the faults in the system, then the coverage factor is less than one and the system has imperfect coverage. An accurate reliability analysis of the system thus must take into consideration the coverage parameter, for systems with imperfect coverage. Methods for incorporation of the coverage parameter in system reliability analysis have been developed. These methods consider the uncovered failure of components both at the subsystem and system level. At the subsystem level, and in the context of hierarchical systems, the uncovered failure of a component can cause the failure of a given subsystem. At the systems level, the uncovered failure of a component can cause systems level failures. One of the mechanisms for including fault tolerance in the system is masking faults using voters. We propose to extend the existing methods for coverage modeling to consider the behavior of voters and their contribution to the prevention of uncovered failures. We consider that the system can have three states: successful, fail covered and fail uncovered and find the likelihood of each of these states as a function of the likelihood of the coverage parameter for each component as well as the likelihood of successful fault masking by the voter.

title: Lunar Laser Ranging with High-Power CW Lasers

description: We present a comprehensive analysis of high-power continuous-wave (CW) lunar laser ranging (LLR) systems designed to achieve sub-millimeter Earth-Moon range precision. Using a 1 kW laser at 1064nm paired with a 1m-aperture telescope, we construct a detailed link budget that ac- counts for beam divergence, atmospheric transmission, retroreflector efficiency, and high-sensitivity single-photon detection. Key challenges include shot-noise limitations under multi-second coherent integration, atmospheric turbulence introducing path fluctuations of 300–500 μm, mechanical and thermal drifts in the optical system, and oscillator stability at the 10^−13–10^−14 level. By maintaining sub-0.01◦C thermal stability and leveraging ultra-stable frequency references, photon fluxes of ∼ 10^4 s−1 are achievable, reducing statistical noise to sub-millimeter levels. We further explore differential LLR, alternating between retroreflectors separated by ∼ 1000 km to suppress common- mode station errors. Under favorable turbulence conditions (r0 ∼ 20 cm), differential ranging precision at the tens-of-μm level is feasible. This “photon-rich” approach—combining high-power CW lasers, dual-wavelength ranging, narrowband filtering, and turbulence averaging—provides a scalable and precise alternative to pulsed-laser systems. Our findings establish high-power CW LLR as a transformative tool for advancing lunar geodesy, refining the lunar reference frame, and enabling next-generation tests of gravitational theories and low-frequency gravitational-wave detection.

description: The National Aeronautics and Space Administration (NASA) Deep Space Optical Communications (DSOC) Project implemented by the Jet Propulsion Laboratory (JPL), has completed weekly optical link demonstrations from November 2023 – December 2024, following the Psyche spacecraft launch in October 2023. The flight laser transceiver, hosted by NASA’s Psyche spacecraft, along with optical ground stations located in Southern California were used. Over this period, downlink data-rates of 6.25 – 267 Mb/s were achieved over deep space distances of 0.2 – 2.7 astronomical units (AU), or 30 – 400 million Km. Optical link acquisition, tracking and pointing was initiated with a modulated uplink laser assembly that also delivered communications at a fixed rate of 1.8 kb/s over distances of 0.2 – 3.3 AU.

title: Study of Hydrologic Connectivity and Tidal Influence on Water Flow Within Louisiana Coastal Wetlands Using Rapid-Repeat Interferometric Synthetic Aperture Radar

description: The exchange of water, sediment, and nutrients in wetlands occurs through a complex network of channels and overbank flow. Although optical sensors can map channels at high resolution, they fail to identify narrow intermittent channels colonized by vegetation. We applied interferometry techniques to rapid-repeat (~30 min) Synthetic Aperture Radar (SAR) imagery of the southern Atchafalaya basin in Louisiana acquired during rising-to-high and ebbing-to-low tides to identify and differentiate permanent open water channels from intermittent channels in which flow varies with tidal conditions and to identify locations where overbank flow occurs. Open water surfaces appear as low interferometric coherence pixels, and the coherence in 60-minute and 90-minute in-terferograms can efficiently identify channels, some less than 10m wide. The channel networks at rising and ebbing tide show significant differences in the extent of flow, with vegetation-filled small channels more clearly identified at rising-to-high tide. InSAR phase change is used to iden-tify locations on channel banks where overbank flow occurs at rising and ebbing tides, which is a critical component for modelling wetland hydrodynamics. SAR maps the channel network in our study area better than the optical instruments tested, particularly the small channels that are pri-marily active at higher tides and extend deep into the island interiors. The study shows the capa-bility of rapid repeat InSAR to track how water moves through wetlands during a tidal cycle

title: An Autoencoder Architecture for L-band Passive Microwave Retrieval of Landscape Freeze-Thaw Cycle

description: —Estimating the landscape and soil freeze-thaw (FT) dynamics in the Northern Hemisphere is crucial for under standing permafrost response to global warming and changes in regional and global carbon budgets. A new framework for surface FT-cycle retrievals using L-band microwave radiometry based on a deep convolutional autoencoder neural network is presented. This framework defines the landscape FT-cycle retrieval as a time series anomaly detection problem, considering the frozen states as normal and the thawed states as anomalies. The autoencoder retrieves the FT-cycle probabilistically through supervised reconstruction of the brightness temperature (TB) time series using a contrastive loss function that minimizes (maximizes) the reconstruction error for the peak winter (summer). Using the data provided by the Soil Moisture Active Passive (SMAP) satellite, it is demonstrated that the framework learns to isolate the landscape FT states over different land surface types with varying complexities related to the radiometric characteristics of snow cover, lake-ice phenology, and vegetation canopy. The consistency of the retrievals is assessed over Alaska using in situ observations, demonstrating an 11% improvement in accuracy and reduced uncertainties compared to traditional methods that rely on thresholding the normalized polarization ratio.

title: NAVIGATION ANALYSIS FOR THE PRIMARY SCIENCE ORBITS OF PARKER SOLAR PROBE

description: Navigation analysis is presented regarding how to best achieve the three primary science orbits for the Parker Solar Probe mission upon completion of the final Venus flyby. It is shown that expected delivery to Venus ensures the primary science requirement is met without additional correction maneuvers and with margin. A linear covariance study and a nonlinear Monte Carlo study are used to verify this result as well as to determine how poor the final Venus delivery would need to be to threaten the prime science requirement. Potential fuel costs of enacting the pre-launch plan of targeting back to a reference perihelion radius at each solar encounter are quantified. Finally, the actual delivery to Venus and the resulting post-flyby trajectory is presented.

title: GUIDANCE, NAVIGATION, AND CONTROL FOR THE DEEP SPACE OPTICAL COMMUNICATION MISSION

description: NASA’s Deep Space Optical Communication (DSOC) mission is currently operating on-board the PSYCHE spacecraft and has demonstrated the first optical communication link from beyond the Earth-Moon system. The opti- cal link requires micro-radian level pointing stability which DSOC achieves through a combination of passive isolation, to reject high frequency distur- bances from the spacecraft, and active pointing control, to track the uplink and downlink stations. The passive isolation is enabled by a floating platform that is tethered to the main spacecraft with soft cables. The floating platform holds a telescope assembly for both receiving the uplink and transmitting the dowlink signals. The floating platform is actively controlled to both reject disturbances from the main spacecraft and to track an uplink signal, which is in turn used as a reference for downlink pointing. In this architecture, down- link pointing control is only used to track the slowly varying drift between the uplink and downlink directions; all pointing isolation is provided by the floating platform control. This allows the dowlink pointing to operate at a nearly fixed point which improves the calibration of the dowlink pointing bias between operational activities. Current experience confirms that the softness and strain in the tethering cables are key design parameters. Furthermore, idiosyncrasies in the sensors used for platform control have, in some instances, hampered pointing performance, which could be resolved in future missions.
