title: Investigation of Convective Updrafts (INCUS) : status after Phase A

description: RainCube (Radar in a CubeSat) and TEMPEST-D (Temporal Experiment for Storms and Tropical Systems - Demonstration) demonstrated in 2018 that deployment of active and passive microwave sensors to monitor storms and precipitation from space is possible on platforms as small as 6U CubeSats. Despite their implementation as high-risk technology demonstrations, with very low budgets compared to their predecessors, they both survived more than two years in orbit (well beyond their commitments). These demonstrations opened the gates to satisfy several long-standing unmet needs by the scientific and operational weather and climate communities. Among them is the need to observe the evolution of the vertical structure of convective storms in the Tropics at the temporal scales relevant to convective processes (i.e., tens of seconds to few minutes) in order to advance our understanding of convective processes and the environmental conditions behind them via modeling and analysis. The INCUS (Investigation of Convective Updrafts) mission concept aims at addressing this need by deploying 3 small satellites each carrying an augmented version of the RainCube radar. One of the 3 small satellites also includes a millimeter wave radiometer inherited from TEMPEST-D. In this presentation we present the status of the INCUS project at the end of Phase A.

title: Electric-Field Pattern Measurements of Acoustically Driven Piezoelectric Field Emitters

description: Piezoelectric transmitters operating at acousticalresonance have been shown to radiate effectively in the VeryLow Frequency (3 kHz to 30 kHz) and Low Frequency regime(30 kHz to 300 kHz). Such transmitters make use of the inversepiezoelectric effect to couple electrical signals into mechanicalvibrations, resulting in near field radiation. This new class ofelectrically small antennas, known as mechanical antennas or‘mechtennas’ can provide several orders of magnitude higherefficiency than similarly sized electrically small conventionaldipoles. Measuring the dipole-like near field pattern of suchpiezoelectric field emitters in the Very Low Frequency and LowFrequency range using conventional techniques is not possible.To address this limitation, a simple capacitor plate-based setupis presented that enables the measurement and plotting of thenear field patterns of such transmitters. Design and simulationof the capacitor plates to model the fields along with electric fieldpattern measurements of a Y 36◦ cut Lithium Niobate transmitterhaving longitudinal mode resonance at 82 kHz are presented.

title: Europa-induced Overlapping of Secondary Resonances in the 4:3 Jupiter-Ganymede Unstable Resonant Orbit Family

description: The overlapping of mean-motion resonances is useful for low-energy space mission design, but while most related prior work uses a planar CRTBP model, tours of multi-moon systems require using resonances affected by two moons. In this work, we investigate Jupiter-Ganymede unstable 4:3 resonant orbits in a concentric circular restricted 4-body model for the Jupiter-Europa-Ganymede system. We show that despite their high order, secondary resonances between these orbits and Europa have a large effect, especially 11/34, 12/37, 23/71, 25/77, 34/105, and 35/108; we also find strong evidence that the associated resonant islands overlap. We then compute many of the new objects which appear inside the secondary resonances, which gives final confirmation of the secondary resonance overlap.

title: Demonstration of Single-picometer Deformable Mirror Wavefront Control Using High-resolution Electronics

description: Deformable mirrors (DMs) are a critical technology to enable coronagraphic direct imaging of exoplanets with current and planned ground- and space-based telescopes as well as future mission concepts, such as the Habitable Worlds Observatory (HWO), which aims to image exoplanet types ranging from gas giants to Earth analogs. These missions set several requirements on the DMs such as large actuator count (≳96x96) and resolution smaller than 2.5 pm. This paper presents the first demonstration of single-picometer wavefront control utilizing a new highresolution, vacuum-compatible DM electronics and a Zernike Wavefront Sensor for measurement. The controller can handle 2,040 actuators with 125 V maximum voltage with 20-bit resolution, resulting in voltage steps of 119 microvolts that allowed us to demonstrate 0.65 pm resolution of the DM surface.

title: Mapping ”Brain Coral” Regions on Mars using Deep Learning

description: One of the key drivers of the Mars Exploration Program is the search for evidence of past or present life. In this context, the most relevant martian environments to search for extant life are those associated with liquid water, and locations that experience periodic thawing of near-surface ice. In this work, we use convolutional neural networks to detect surface regions containing ``Brain Coral'' terrain, a landform on Mars whose similarity in morphology and scale to sorted stone circles on Earth suggests that it may have formed as a consequence of freeze/thaw cycles. We use high-resolution images ($\sim$100-1000 megapixels) acquired by the Mars Reconnaissance Orbiter to search for these landforms at resolutions close to a few tens of centimeters per pixel (25--50 cm). Over 52,000 images ($\sim$28 TB) were searched ($\sim$5\% of the Martian surface) where we find detections in over 150 images. To expedite the processing we leverage a classifier network (prior to segmentation) in the Fourier domain that can take advantage of JPEG compression by leveraging blocks of coefficients from a discrete cosine transform in lieu of decoding the entire image at the full spatial resolution. The hybrid pipeline approach maintains $\sim$96$\%$ accuracy while cutting down on $\sim$80$\%$ of the total processing time compared to running the segmentation network at the full resolution on every image. The timely processing of big data sets helps inform mission operations, and geologic surveys to prioritize candidate landing sites, avoid hazardous areas or map the spatial extent of specific terrain.

title: Performance of the SPARCS UV camera and detectors

description: The Star-Planet Activity Research CubeSat (SPARCS) is 6U CubeSat whose mission will be to observe low-mass stars in two ultraviolet (UV) bands. SPARCS will provide time-dependent spectral slope, intensity, and evolution of stellar radiation with the goal of understanding the short- and long-term variability of these targets. Here we summarize the performance of SPARCam, the science camera for SPARCS. SPARCam is a two-detector camera system allowing independent commanding of two delta-doped, UV CCD47-20 detectors, separately optimized for the SPARCS near UV (NUV) and far UV (FUV) bands. The manuscript includes an overview of the UV detectors optimization and performance as well as a brief description of the camera electronics. SPARCam was designed and built by the Jet Propulsion Laboratory and delivered to Arizona State University in October 2023.

title: Optimal Orbits for Imaging Super Massive Black Holes using Space VLBI

description: The diameter of the Earth constitutes a fundamental limit to current efforts of imaging supermassive black holes (SMBH). The current Event Horizon Telescope (EHT), a network of telescopes employing very long baseline interferometry (VLBI), is sufficient only for imaging M87*, due to its large mass, and SgrA*, the SMBH in the center of our galaxy. A future black hole imager requires moving from ground to space-based VLBI. Here, we investigate the benefits of augmenting the current EHT with space-based antennas that are either Earth orbiting, orbiting in cislunar space, or in a Sun-Earth Lagrange point orbit. We use evolutionary optimization algorithms to search for the trajectories in these regions that maximize diversity of antenna separations.

title: Sample Retrieval Lander Parachute System Deployment Test Campaigns: Modeling, Testbed Development, and Intermediate Results

description: A 24-meter Disk-Gap-Band (DGB) mortar-deployed parachute is being developed for the Sample Retrieval Lander as part of the proposed Mars Sample Return mission. This parachute will both larger and heavier than previous Mars missions, requiring a high mortar muzzle velocity to achieve a suitable bag strip ratio for successful deployment. A simple model was generated to predict the relative velocity between the parachute canopy and the deployment bag during bag strip. To reduce risk of canopy damage and better understand mortar velocity upper bound, the Dynamic Extraction Testbed originally used for ExoMars testing was revamped to simulate parachute deployment at high velocity. A test campaign was planned, using a 300-foot zipline and force device to accelerate a trolley above the maximum predicted velocity of 61 m/s and drop the parachute pack. This campaign has yet to been conducted, but all dynamic modeling is complete and ground support equipment has been designed. A separate mortar ground test campaign was developed to validate the deployment system and ensure that target muzzle velocity could be met. Two of the ten proposed tests have been conducted. Results from the first test indicate unforeseen dynamics associated with the larger system, leading to higher-than-predicted muzzle velocities. These findings were used to refine the mortar model, which then accurately predicted the velocity of the second deployment. A range of data was collected, including high-speed video, dynamic response of the test stand and mortar tube, pressure readings in the mortar tube and gas generator, reaction load, and bridle pin load. Future tests will focus on qualifying the system at temperature requirements.

title: Hardware development towards the demonstration of an ideal photonic coronagraph

description: The Habitable Worlds Observatory aims to detect and characterize Earth-like exoplanets orbiting around Sun-like stars. Current coronagraph technology is not yet capable of reaching the required 1E-10 contrasts; however, advancements in photonic technologies may be able to fill this gap. A significant challenge in astrophotonics is the efficient coupling of light from the telescope into the photonic device. To address this, we have manufactured a photonic device incorporating a spatial array of photonic lanterns, designed to couple light in the focal plane into the device, even in the presence of aberrations. Additionally, we have constructed a testbed for the free-space coupling of light into photonic devices. This testbed is equipped with a segmented deformable mirror (DM) for inducing controlled phase aberrations and a vectorized Zernike wavefront sensor (vZWFS) for direct electric field measurement in the pupil plane. Our device comprises seven mode-sorting photonic lanterns arranged in a hexagonal layout, each coupling light into three modes: LP01, LP11a, and LP11b. This lantern array, paired with a dynamic photonic integrated circuit (PIC), forms the architecture of a near-ideal photonic coronagraph. We describe the development of the testbed, the preliminary characterization of the photonic lantern array, and present preliminary images through the device.
