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: A Separated Thinned Array Concept for Remote Sensing of Antarctic Ice Sheet Temperature

description: We present a concept for L band remote sensingof Antarctic ice sheet temperature using a separated thinnedinterferometric array. This concept leverages the relative stabilityof ice sheet thermal emission over long periods of time togradually assemble a collection of array baselines which arejointly transformed to develop large image facets. From anassessment of feasibility, we determine that such a system ispossible for achieving 1-10 kilometer spatial resolution overmonthly to yearly timescales with as few as 10-20 elements; evenfewer elements are required for sensing the ice sheet center. Theimage reconstruction problem is posed as a data constraint inthe Fourier domain with an total variational regularization in theimage domain. We use ice sheet thermomechanical and radiativetransfer modeling to develop realistic ice sheet images, and theseimages are used in observing system simulations to demonstratethe proposed approach.

title: Terrestrial Demonstration of Orbital Mapping and Validation Capabilities over a Lunar Surface Analog

description: The Lunar Navigation Maps (LuNaMaps) project has improved existing tools and processes and developed new tools and processes to support the generation and validation of navigation maps of the lunar surface from orbital imagery. To demonstrate the advancements made through the LuNaMaps project, we con-ducted a terrestrial demonstration obtaining “orbital” imagery of the Lunar Sur-face Proving Ground (LSPG) at Astrobotic’s test facility in Mojave California. The LSPG is a 100 m by 100 m pad built to mimic the features and appearance of the lunar surface. In this paper we describe the planning and results of the test, including the capture of imagery for building the maps, the map building processes, building of a “truth map” using traditional surveying tools, and the map validation processes. We demonstrate how the built map compares to the “truth map” and how the validation processes provided insight to this compari-son. Additionally, we describe an upcoming partner test in which the naviga-tion maps will be used in a terrain relative navigation (TRN) technology demonstration over the same LSPG surface.

title: Motion Primitive Approach to Spacecraft Trajectory Design in the Neptune-Triton System

description: A motion primitive approach is used to design spacecraft trajectories from a high-energy interplanetary arrival condition to a 3:4 resonant orbit in the Neptune-Triton system. A motion primitive library is constructed by using clustering to summarize arcs along periodic orbit families and their hyperbolic invariant manifolds in the circular restricted three-body problem. A graph that captures their potential connectivity is then searched to form motion primitive sequences. Selected sequences are refined and corrected to produce geometrically distinct spacecraft trajectories with flight times as low as 12.60 days and total impulsive maneuver requirements as low as 1.64 km/s.

title: GUIDANCE, NAVIGATION CONTROL FOR THE PSYCHE MISSION

description: The Psyche spacecraft is enroute to the asteroid of the same name. Located in the main belt, the asteroid is of great scientific interest because it is likely rich in metal. The metal may be from the core of a planetesimal, one of the building blocks of the Sun’s planetary system. At (16) Psyche scientists will explore, for the first time ever, a world made not of rock or ice, but rich in metal. The mis-sion is enabled by electric propulsion; it is the first to use Hall-effect thrusters beyond lunar orbit. By handling the novel challenges of the new use case for the technology, the spacecraft’s Guidance, Navigation Control (GNC) sub-system helps enable the mission. It also helps to enable the advancement of new technology to return more science data faster. The spacecraft hosts the Deep Space Optical Communication (DSOC) demonstration, which tests a sophisti-cated new laser communication technology to communicate between a probe in deep space and Earth. Several pointing performance requirements and interfaces support the technology.

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: Stellar Contamination Correction Using Back-to-Back Transits of TRAPPIST-1 b and c

description: Stellar surface heterogeneities, such as spots and faculae, often contaminate exoplanet transit spectra, hindering precise atmospheric characterization. We demonstrate a novel, epoch-based, modelindependent method to mitigate stellar contamination, applicable to multi-planet systems with at least one airless planet. We apply this method using quasi-simultaneous transits of TRAPPIST-1 b and TRAPPIST-1 c observed on July 9, 2024, with JWST/NIRSpec PRISM. These two planets, with nearly identical radii and impact parameters, are likely either bare rocks or possess thin, low-pressure atmospheres, making them ideal candidates for this technique, as variations in their transit spectra would be primarily attributed to stellar activity. Our observations reveal their transit spectra exhibit consistent features, indicating similar levels of stellar contamination. We use TRAPPIST-1 b to correct the transit spectrum of TRAPPIST-1 c, achieving a 2.5× reduction in stellar contamination at shorter wavelengths. At longer wavelengths, lower SNR prevents clear detection of contamination or full assessment of mitigation. Still, out-of-transit analysis reveals variations across the spectrum, suggesting contamination extends into the longer wavelengths. Based on the success of the correction at shorter wavelengths, we argue that contamination is also reduced at longer wavelengths to a similar extent. This shifts the challenge of detecting atmospheric features to a predominantly white noise issue, which can be addressed by stacking observations. This method enables epoch-specific stellar contamination corrections, allowing co-addition of planetary spectra for reliable searches of secondary atmospheres with signals of 60–250 ppm. Additionally, we identify small-scale cold (∼2000 K) and warm (∼2600 K) regions almost uniformly distributed on TRAPPIST-1, with overall covering fractions varying by ∼0.1% per hour.

title: The Small Mobile Ozone Lidar (SMOL): instrument description and first results

description: Ozone profile measurements at high temporal and vertical resolution are needed to better understand physical and chemical processes driving tropospheric ozone variability and to validate the tropospheric ozone measurements from spaceborne missions such as TEMPO (Tropospheric Emissions: Monitoring Pollution). As part of the Tropospheric Ozone Lidar Network (TOLNet) efforts allocated to provide such measurements and leveraging on the experience of more than 20 years of ozone lidar measurements at Table Mountain Facility, the JPL lidar group developed the SMOL (Small Mobile Ozone Lidar), an affordable differential absorption lidar (DIAL) system covering all altitudes from 200 to 10 km above ground level (a.g.l.). The transmitter is based on a quadrupled Nd:YAG laser, which is further converted into a 289/299 nm wavelength pair using Raman shifting cells, and the receiver consists of three ozone DIAL pairs, including one that is 266/289 nm and two that are 289/299 nm. Two units were deployed in the Los Angeles basin area during the Synergistic TEMPO Air Quality Science (STAQS) and Atmospheric Emissions and Reactions Observed from Megacities to Marine Areas (AEROMMA) campaigns in summer 2023. The comparison with airborne in situ and lidar measurements shows very good agreement, with systematic differences below 10% throughout most of the measurement range.

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: 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: Developing Contingency Options for INCUS: Differential Drag for Constellation Maintenance

description: INCUS is a NASA Earth Venture Mission expected to launch in 2026. The INCUS constellation is composed of three low-thrust smallsats (Observatories) flying in formation in low Earth orbit, with the second and third Observatories are separated by approximately 30 and 120 seconds in-track from the first Observatory. In this paper, we demonstrate that differential drag is a robust backup option for the maintenance of the phasing offsets between the Observatories. Algorithms for defining high- and low-drag windows are detailed and notional maintenance maneuvers are generated. The impact of the altitude, solar flux, and spacecraft properties on the timing and duration of the differential drag maneuvers is explored in sensitivity study. An improved shape model for the Observatory is constructed to get a refined estimate of the frequency of the phasing maintenance.
