title: Covariance–based rational approximations of fractional SPDEs for computationally efficient Bayesian inference

description: The stochastic partial differential equation (SPDE) approach is widely used for modeling large spatial datasets. It is based on representing a Gaussian random field <i>u</i> on Rd as the solution of an elliptic SPDE Lβu=W where <i>L</i> is a second-order differential operator, 2β∈N is a positive parameter that controls the smoothness of <i>u</i> and W is Gaussian white noise. A few approaches have been suggested in the literature to extend the approach to allow for any smoothness parameter satisfying β&gt;d/4. Even though those approaches work well for simulating SPDEs with general smoothness, they are less suitable for Bayesian inference since they do not provide approximations which are Gaussian Markov random fields (GMRFs) as in the original SPDE approach. We address this issue by proposing a new method based on approximating the covariance operator L−2β of the Gaussian field <i>u</i> by a finite element method combined with a rational approximation of the fractional power. This results in a numerically stable GMRF approximation which can be combined with the integrated nested Laplace approximation (INLA) method for fast Bayesian inference. A rigorous convergence analysis of the method is performed and the accuracy of the method is investigated with simulated data. Finally, we illustrate the approach and corresponding implementation in the R package rSPDE via an application to precipitation data which is analyzed by combining the rSPDE package with the R-INLA software for full Bayesian inference.

title: Preparation for High-Frequency Wave Dispersion Relation Measurements Using LIF, and Comparison of Ion Velocities in Stand-Alone Cathode Testing versus Hall Thruster Operation

description: Ion heating by waves in the lower hybrid frequency range that are driven unstable by density gradients and cross-field ion flow has been identified as a likely driver of front pole erosion in NASA's Hall Effect Rocket with Magnetic Shielding (HERMeS). To validate this proposed mechanism's inclusion in thruster life simulations carried out with the Hall2De code, we are pursuing non-invasive measurements of the relevant wave dispersion relations using laser-induced fluorescence (LIF). This paper presents the derivations of the first-order perturbed ion velocity distribution function (IVDF) and the phase-sensitive detection steps that are needed to complete these measurements. A demonstration of our capability to resolve high-frequency electrostatic waves will first be carried out in a stand-alone hollow cathode test setup. We have also measured time-averaged ion velocities in the cathode plume, with two different cylindrical anode diameters. In this paper, the velocity vectors are compared with those previously measured in the cathode plume during thruster operation, and they are shown to be in reasonably good agreement for both anode sizes. We find that the mean radial ion velocities at the edge of the cathode plume are smaller in the thruster than in the stand-alone cathode configurations due to the presence of a secondary ion population streaming radially inwards from the region in front of the inner pole.

title: Testing Results from Pathfinder 2k x 2k HgCdTe Infrared Detectors for the Near Earth Object Surveyor Mission

description: The Near Earth Object (NEO) Surveyor, a NASA planetary defense space mission, is currently in Phase B with a launch date in 2026. NEO Surveyor is an infrared telescope designed to detect and characterize Potentially Hazardous Asteroids (PHAs). The required sensors leverage the space flight heritage and further development over the last 15 years of HgCdTe detectors to detect infrared light spanning from 4 to 10 μm . NEO Surveyor will employ eight passively cooled HgCdTe focal plane assemblies (FPAs) across two bands, each band consisting of a 1x4 configuration to cover a wide field of view. Four of these FPAs have a &gt; 6 μm cutoff wavelength and cover the shorter 4-5.2 μm (NC1) band, while four FPAs will have a &gt; 10.5 μm cutoff wavelength and span the longer 6-10 μm (NC2) band. We present characterization and performance results from two recently produced pathfinder FPAs, one for each band, manufactured by Teledyne Imaging Sensors with development guidance from the University of Arizona, the University of Rochester, IPAC/Caltech, and JPL. Both devices demonstrate the requisite low levels of dark current, high well depth, and exceptional quantum efficiency, exceeding mission requirements.

title: Characterization of Multilayer Piezoelectric Stacks down to 100 K for Surface Parallel Mirror Actuation

description: – The next generation of space telescopes will require large segmented apertures for observations in the near ultraviolet through mid and far infrared regions to enable new science ranging from exoplanet characterization to precision astronomical observations that refine astrophysics models. Recent concept studies, such as LUVOIR, HabEx, and Origins, and the future IR/O/UV Large Strategic Mission telescope for exoplanet characterization and general astronomy discussed in the 2021 Decadal Survey “Pathways to Discovery in Astronomy and Astrophysics for the 2020s,” include segmented telescopes which are capable of observations in UV through IR bands, and thus drive the need for optical surface performance at cryogenic temperatures. These spaceborne mirror applications require precision control, and these segments will require actuators for controlled surface displacements capable of operation at cryogenic temperatures (&lt;150 K). This paper presents a testbed mirror design to test out new actuators and control strategies. This work is directed at understanding the performance of piezoelectric multilayer stack actuator operation down to 100 K, which will provide actuator designers the critical information needed to model and predict performance. The data reported down to 100 K includes: displacement/strain and capacitance as a function of applied voltage, stiffness, hysteresis, blocking force, DC resistance measurements, thermal strains and the coefficients of thermal expansion as a function of the electrical boundary conditions. The actuators include a strain gauge to allow for closed loop control. This approach allows for a comparison of potential open loop control drive strategies and associated errors reported in previous work. Surface actuation measurements using flexure-based actuators on aluminum mirror segments at room temperature will also be presented. In addition, we will present techniques to optimize displacement per voltage using amplified piezoelectric flexures and the potential to develop mirrors that can be operated at cryogenic temperatures by carefully choosing flexure materials and geometry.

title: Absolute Flux Calibrations for the Nancy Grace Roman Space Telescope Coronagraph Instrument

description: The Nancy Grace Roman Space Telescope’s (Roman) Coronagraph Instrument is a technology demonstration equipped to achieve flux contrast levels of up to 10−9. This precision depends upon the quality of observations and their resultant on-sky corrections via an absolute flux calibration (AFC). Our plan utilizes 10 dim and 4 bright standard photometric calibrator stars from Hubble Space Telescope’s (HST) CALSPEC catalog to yield a final AFC error of 1.944% and total observation time of ∼22 minutes. Percent error accounts for systematic uncertainties in Roman component instrumentation along with shot noise for a signal to noise ratio (SNR) of 500.

title: Closure of Earth’s Global Seasonal Cycle of Energy Storage

description: The global seasonal cycle of energy in Earth’s climate system is quantified using observations and reanalyses. After removing long-term trends, net energy entering and exiting the climate system at the top-of-the-atmosphere (TOA) should agree with the sum of energy entering and exiting the ocean, atmosphere, land, and ice over the course of an average year. Achieving such a balanced budget with observations has been challenging (Fasullo and Trenberth 2008; McKinnon and Huybers 2016). Disagreements have been attributed previously to sparse observations in the high latitude oceans. However, limiting the local vertical integration of new global ocean heat content estimates to the depth to which seasonal heat energy is stored, rather than integrating to 2000 m everywhere as done previously, allows closure of the global seasonal energy budget within statistical uncertainties. The seasonal cycle of energy storage is largest in the ocean, peaking in April because ocean area is largest in the Southern Hemisphere and the ocean’s thermal inertia causes a lag with respect to the austral summer solstice. Seasonal cycles in energy storage in the atmosphere and land are smaller, but peak in July and September, respectively, because there is more land in the Northern Hemisphere, and the land has more thermal inertia than the atmosphere. Global seasonal energy storage by ice is small, so the atmosphere and land partially offset ocean energy storage in the global integral, with their sum matching time-integrated net global TOA energy fluxes over the seasonal cycle within uncertainties, and both peaking in April.

title: Molecular Transport Conditions Required for the Formation of Penitentes on Airless, Ice-Covered Worlds, with Specific Application to Europa, Enceladus, and Callisto

description: The surface morphology of airless, ice-covered moons of the outer solar system, such as Europa, Enceladus, and Callisto, is not well known at centimeter- to meter-scales. Ice and snow erode differently on such worlds in part because sublimation is the dominant process. On Earth, ice penitentes have been observed in sublimation-driven environments, and may provide a guide for similar formations on ice-covered worlds. Penitentes are blade-like snow features observed on Earth in high-altitude, low-latitude snowfields. Models of penitente formation on Earth break down within the free-molecular regime of airless bodies, leaving a major gap in understanding whether such morphologies can form on their surfaces. To investigate the morphologic evolution of icy bodies, we developed a Sublimation Monte Carlo (SMC) model that enables a numerical approach to modeling exosphere-surface interactions at free-molecular conditions. The SMC model uses Monte Carlo tracking of molecules emitted from the surface to determine the net molecular interchange that drives surface changes. We validated results against experiments, matching the evolution of pre-formed penitentes as they receded in height and became less pronounced. Our results reveal the importance of molecular redeposition on topology, indicating that the stable morphology of isothermal topographies is a planar morphology on regions of net sublimation, regardless of initial surface shape. A study of parametrically varying temperature profiles for sinusoidal penitentes resulted in the following requirement for penitente growth: the trough temperature must exceed the peak temperature by a threshold value, which notably depends on the surface aspect ratio and peak temperature.
