title: Adding Radiation Induced Conductivity Test Capability to the JPL Dynamitron

description: The Europa Clipper space environments test campaign has made extensive use of the Dynamitron electron accelerator located at the Jet Propulsion Laboratory. One of the most common uses of this facility has been gathering data on the internal electrostatic discharge (IESD) properties of the various elements of the spacecraft. These testing needs often required some reconfiguration of the accelerator system. One of the most recent upgrades was adding the ability to measure both dark conductivity and radiation induced conductivity (RIC) for spacecraft materials. Adding this new one-of-a-kind capability required incorporating a low energy electron flood gun to the existing higher energy electron beam from the Dynamitron accelerator. The upgraded system was also designed to obtain data on multiple samples per test run allowing for the acquisition of a large quantity of data in a relatively short time period. Dark and radiation induced conductivities measured using the new system are provided demonstrating examples of the of results that can be obtained.

title: Spiral Arms are Metal Freeways: Azimuthal Gas-Phase Metallicity Variations in Flocculent Disks in the FIRE-2 Cosmological Zoom-in Simulations

description: We examine the azimuthal variations in gas-phase metallicity profiles in simulated Milky Way mass disk galaxies from the Feedback in Realistic Environments (FIRE-2) cosmological zoom-in simulation suite, which includes a sub-grid turbulent metal mixing model. We produce spatially resolved maps of the disks at I   0 with pixel sizes ranging from 250 to 750 pc, analogous to modern integral field unit (IFU) galaxy surveys, mapping the gas-phase metallicities in both the cold & dense gas and the ionized gas correlated with HII regions.We report that the spiral arms alternate in a pattern of metal rich and metal poor relative to the median metallicity on the order of . 01 dex, appearing generally in this sample of flocculent spirals. The pattern persists even in a simulation with different strengths of metal mixing, indicating that the pattern emerges from physics above the sub-grid scale. Local enrichment does not appear to be the dominant source of the azimuthal metallicity variations at I   0: there is no correlation with local star formation on these spatial scales. Rather, the arms are moving radially inwards and outwards relative to each other, carrying their local metallicity gradients with them radially before mixing into the larger-scale interstellar medium. We propose that the arms act as freeways channeling relatively metal poor gas radially inwards, and relatively enriched gas radially outwards.

title: Galaxy cluster shapes inferred from weak lensing as a probe of dark matter self-interactions

description: We investigate whether the shapes of galaxy clusters inferred from weak gravitational lensing can be used as a test of the nature of dark matter. We analyse mock weak lensing data, with gravitational lenses extracted from cosmological simulations run with two different dark matter models (CDM and SIDM). We fit elliptical NFW profiles to the shear fields of the simulated clusters. Despite large differences in the distribution of 3D shapes between CDM and SIDM, we find that the distributions of weak-lensing-inferred cluster shapes are almost indistinguishable. We trace this information loss to two causes. Firstly, weak lensing measures the shape of the projected mass distribution, not the underlying 3D shape, and projection effects wash out some of the difference. Secondly, weak lensing is most sensitive to the projected shape of clusters, on a scale approaching the virial radius ($\sim 1.5 \mpc$), whereas SIDM shapes differ most from CDM in the inner halo. We introduce a model for the mass distribution of galaxy clusters where the ellipticity of the mass distribution can vary with distance to the centre of the cluster. While this mass distribution does not enable weak lensing data to distinguish between CDM and SIDM with cluster shapes (the ellipticity at small radii is poorly constrained by weak lensing), it could be useful when modelling combined strong and weak gravitational lensing of clusters.

title: A Path to Solving Robotic Differential Equations Using Quantum Computing

description: Quantum Computing and Quantum Information Science is a burgeoning engineering field at the cusp of solving challenging robotic applications. This paper introduces a hybrid (gate-based) quantum computing and classical computing architecture to solve the motion propagation problem for a robotic system. This paper presents the quantum-classical architecture for linear differential equations defined by two types of linear operators: Unitary and Non-Unitary system matrices, thereby solving any linear ordinary differential equation. The ability to encode information using bits — or qubits — is essential in any computation problem. The results in this paper also introduce two novel approaches to encoding any arbitrary state vector or any arbitrary linear operator using qubits. Unlike other algorithms that solve ODEs using purely quantum or classical architectures, the ODE solver presented in this paper leverages the best of quantum and classical computing paradigms.

title: Doppler Constraints on Planetary Companions to Nearby Sun-like Stars: An Archival Radial Velocity Survey of Southern Targets for Proposed NASA Direct Imaging Missions

description: Directly imaging temperate rocky planets orbiting nearby, Sun-like stars with a 6-m-class IR/O/UV space telescope, recently dubbed the Habitable Worlds Observatory, is a high pri- ority goal of the Astro2020 Decadal Survey. To prepare for future direct imaging surveys, the list of potential targets should be thoroughly vetted to maximize efficiency and scientific yield. We present an analysis of archival radial velocity data for southern stars from the NASA/NSF Extreme Precision Radial Velocity Working Group’s list of high priority target stars for future direct imaging missions (drawn from the HabEx, LUVOIR, and Starshade Rendezvous studies). For each star, we constrain the region of companion mass and period parameter space we are already sensitive to based on the observational baseline, sampling, and precision of the archival RV data. Additionally, for some of the targets we report new estimates of magnetic activity cycle periods, rotation periods, improved orbital parameters for previously known exoplanets, and new candidate planet signals that require further vetting or observations to confirm. Our results show that for many of these stars we are not yet sensitive to even Saturn-mass planets in the habitable zone, let alone smaller planets, highlighting the need for future EPRV vetting efforts before the launch of a direct imaging mission. We present evidence that the candidate temperate super-Earth exoplanet HD 85512b is most likely due to the star’s rotation, and report a RV acceleration for δ Pav which supports the existence of a distant giant planet previously inferred from astrometry.

title: TBIRD 200-Gbps CubeSat Downlink: System Architecture and Mission Plan

description: The Terabyte Infrared Delivery (TBIRD) program will establish an optical communication link from a 6U CubeSat in low-Earth orbit (LEO) to a ground station at burst rates up to 200 Gbps, resulting in data volumes that can exceed 1 Terabyte in a single pass. The space and ground terminals utilize commercially available 1550-nm coherent transceivers in conjunction with an automatic repeat request (ARQ) system to guarantee robust communication in the presence of an atmospheric fading channel. This allows the system to perform a reliable end-toend transfer of data from the payload’s 2-TB storage buffer to the ground terminal. In this paper, we describe the system architecture, link analysis, and concept of operations for the upcoming TBIRD flight demonstration in 2022. We also provide an update on the development of the 3U terminal payload and the ground terminal at JPL’s Optical Communications Telescope Laboratory (OCTL).

title: Update: Modeling Supersonic Parachute Inflations for Mars Spacecraft

description: This work serves as an update on recent progress made by the Jet Propulsion Laboratory, California Institute of Technology/Stanford/Stevens Institute of Technology team working on performing high-fidelity fluid-structure interaction (FSI) simulations for modeling supersonic parachute inflations relevant for Mars spacecraft. A key finding discussed in the present work is the generation of a toroidal vortex inside the parachute canopy during inflation, and the significance of how the system-level drag is influenced by this toroidal vortex trajectory as the parachute peak load and subsequent unloading is reached. In addition to reporting on technical modeling progress, this work also includes detailed information on the Advanced Supersonic Parachute Inflation Research Experiment (ASPIRE) SR02 parachute geometry and material properties so that additional researchers in the community can compare parachute simulation results to ASPIRE flight data.

title: Structure of the Plasma near the Heliospheric Current Sheet as seen by WISPR/Parker Solar Probe from Inside the Streamer Belt

description: Parker Solar Probe crossed the Heliospheric Current Sheet (HCS) near perihelion on Encounters E8 and E11, enabling the Wide-field Imager for Solar Probe (WISPR) to image the streamer belt plasma in high resolution while flying through it. With perihelia of 16~R$_\sun$ and 13~R$_\sun$ for E8 and E11, respectively, WISPR images enable investigation of the structure of density encasing the HCS at much higher resolution than reported previously. As PSP flies closer to the Sun, fine scale structure is resolved within the rays of the streamer belt. Near the HCS, WISPR observes a fan of rays of varying size and brightness, indicating large density variations along the HCS. Near perihelion, when PSP’s speed exceeds the solar co-rotation speed, some rays exhibit large changes in \textit{apparent} latitude as the HCS is encountered and rays pass over and under the spacecraft. The multiple viewpoints provided during the HCS crossing enable us to extract the coordinates of a few rays in a heliocentric frame. The rays were found to lie near the HCS from a PFSS model. We compare their locations to the location of the streamers as seen in synoptic maps from the Large Angle and Spectrometric COronagraph (LASCO), and find that the rays generally fall within the bright/high density regions seen in these maps, which confirms that they are features of the streamer belt plasma along the HCS. We speculate that the density variations in the helmet streamer plasma result from continuous interchange reconnection along the coronal hole boundaries.

title: Performance of the Adaptive Optics System for Laser Communication Relay Demonstration’s Ground Station One

description: The Laser Communication Relay Demonstration is NASA's multi-year demonstration of laser communication to a geosynchronous satellite. The mission currently has two optical ground stations (OGS), with one in California (OGS1) and one in Hawaii (OGS2). The optical system consists of an high order adaptive optics system, the transmit system and a camera for target acquisition. The adaptive optics (AO) system is responsible for compensating the downlink beam for atmospheric turbulence and coupling it into the modem's single mode fiber. The mission required a coupling efficiency of 50% which necessitates a high-order AO system. To achieve this performance, the adaptive optics system uses two deformable mirrors with one mirror correcting for low spatial frequencies aberrations with large amplitude and a second deformable mirror correcting for high spatial frequencies aberrations with small amplitude. The system uses a Shack-Hartmann wavefront sensor. Another aspect of the system design necessary to achieve the system performance under the stressing turbulence conditions is a system bandwidth. The system can operate at framer rates of 20 kHz. We present an overview of the design of the system and measured AO system performance.
