title: Radio Propagation Environment Modeling and Learning for Networked Multi-Robot Exploration

description: Multi-robot exploration of complex, unknown environments benefits from the collaboration and cooperation offered by inter-robot communication. Accurate radio signal strength prediction enables communication-aware exploration. Models which ignore the effect of the environment on signal propagation or rely on a priori maps suffer in unknown, communication-restricted (e.g. subterranean) environments. In this work, we present Propagation Environment Modeling and Learning (PropEM-L), a framework which leverages real-time sensor-derived 3D geometric representations of an environment to extract information about line of sight between radios and attenuating walls/obstacles in order to accurately predict received signal strength (RSS). Our data-driven approach combines the strengths of well-known models of signal propagation phenomena (e.g. shadowing, reflection, diffraction) and machine learning, and can adapt online to new environments. We demonstrate the performance of PropEM-L on a six-robot team in a communicationrestricted environment with subway-like, mine-like, and cave-like characteristics, constructed for the 2021 DARPA Subterranean Challenge. Our findings indicate that PropEM-L can improve signal strength prediction accuracy by up to 44% over a logdistance path loss model.

title: The Distribution of UV Radiation Field in the Molecular Clouds of Gould Belt

description: The distribution of ultraviolet (UV) radiation field provides critical constraints on the physical environments of molecular clouds. Within 1 kpc of our solar system and fostering protostars of different masses, the giant molecular clouds in the Gould Belt present an excellent opportunity to resolve the UV field structure in star-forming regions. We performed spectral energy distribution (SED) fitting of the archival data from the Herschel Gould Belt Survey (HGBS). Dust radiative transfer analysis with the DUSTY code was applied to 23 regions in 14 molecular complexes of the Gould Belt, resulting in the spatial distribution of the radiation field in these regions. For 10 of 15 regions with independent measurements of star formation rate, their star formation rate and UV radiation intensity largely conform to a linear correlation found in previous studies.

title: Exceptional preservation of organic matter and iron-organic colloidal mineralization in hydrothermal black 3 smoker-type sulfide mineralization from the Paleoarchean seafloor

description: Fossil organic matter (OM) in Paleoarchean rocks is an invaluable tracer of ancient life, yet it is often contentious due to low preservation potentials of its original organic molecular characteristics under generally high metamorphic grades. This study reports on exceptionally preserved OM within black smoker-type sulfide mineralizations from the 3.24 billion-years-old Sulphur Springs volcanic-hosted massive sulfide deposit, East Pilbara Terrane, northwestern Australia. Fine scale mineralogical and organic molecular variations – documented by SEM and TEM techniques, Raman and FTIR Spectroscopy, as well as ToF-SIMS analysis – trace the formation of millimetre-scale pyritic hydrothermal orifices. Overmature OM (≳200-250 ˚C) enriched in aromatic hydrocarbons occurs within earliest formed colloform-banded pyrite that could have precipitated at high temperature upon mixing of hot hydrothermal fluids with cold seawater. In contrast, mature OM (within the catagenesis window; ~100-150 ˚C) with lower proportions of aromatic hydrocarbons occasionally occurs alongside pyrite within barite near the inner paleofluid conduits of the hydrothermal orifices. A deposition of this OM generation from cooler fluids enriched in sulfate during waning hydrothermal activity is corroborated by its association with original mineralogy, particularly the occurrence of isolated nanoinclusions of OM within hydrothermal barite away from grain boundaries or fissures and cracks, which renders impossible an origin from post-depositional hydrocarbon migration. When compared to the overmature OM within colloform banded pyrite, the better-preserved inner OM not only contains less abundant, smaller, and less ordered aromatic hydrocarbons, but also higher amounts of aliphatic molecules with longer chain lengths and higher proportions of carbonyl and amide functional groups. Although the latter characteristics are consistent with contributions by microbial biomass, abiotic origins cannot be discounted because hydrothermal processes can produce OM with similar organic molecular attributes. Irrespective of these uncertainties on the ultimate sourcing of OM, common intergrowths of the cooler OM with nanoscopic iron oxides – hematite and lesser magnetite – hint at its hydrothermal deposition from colloidal particles that have been stabilized by iron organic complexation. Further research is required to ascertain the significance of this process for the hydrothermal cycling and release of organic carbons and bound iron into the Paleoarchean oceans. Collectively, our results show that ancient marine hydrothermal systems can preserve OM with differing degrees of thermal degradation, which allows for insights into its sourcing, cycling, and deposition.

title: ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -XIII. Ongoing triggered star formation within clump-fed scenario found in the massive (∼ 1500 M⊙) clump

description: Whether ionization feedback triggers the formation of massive stars is highly debated. Using ALMA 3 mm observations with a spatial resolution of ∼ 0.05 pc and a mass sensitivity of 1.1 M⊙ beam−1 at 20 K, we investigate the star formation and gas flow structures within the ionizing feedback-driven structure, a clump-scale massive (≳ 1500 M⊙) bright-rimmed cloud (BRC) associated with IRAS 18290−0924. This BRC is bound only if external compression from ionized gas is considered. A small-scale (≲ 1 pc) age sequence along the direction of ionizing radiation is revealed for the embedded cores and protostars, which suggests triggered star formation via radiation-driven implosion (RDI). Furthermore, filamentary gas structures converge towards the cores located in the BRC’s center, indicating that these filaments are fueling mass towards cores. The local core-scale mass infall rate derived from H13CO+ 𝐽 = 1 − 0 blue profile is of the same order of magnitude as the filamentary mass inflow rate, approximately 1 M⊙ kyr−1. A photodissociation region (PDR) covering the irradiated clump surface is detected in several molecules, such as CCH, HCO+, and CS whereas the spatial distribution stratification of these molecules is indistinct. CCH spectra of the PDR possibly indicate a photoevaporation flow leaving the clump surface with a projected velocity of ∼ 2 km s−1. Our new observations show that RDI accompanied by a clump-fed process is operating in this massive BRC. Whether this combined process works in other massive BRCs is worth exploring with dedicated surveys.

title: Crystallization Kinetics of Vitreous Magnesium Sulfate Hydrate and Implications for Europa’s Surface

description: Brines consistent with that expected for Europa’s global subsurface ocean have been shown to form vitreous salt hydrates when frozen. We report experiments examining the crystallization kinetics of vitreous MgSO4 hydrate in order to better understand the stability of such materials on the surface of Europa. Vitreous MgSO4 hydrates formed from a 2 M parent solution were found to crystallize into MgSO4•11H2O (meridianiite) upon annealing at 195-225 K. Raman spectroscopy was used to monitor the crystallization and reaction rates were determined from the growth of the crystalline fraction as a function of time. Arrhenius analysis yielded an activation energy of 60 kJ/mol for the vitreous to crystalline transition, implying that such transformation does not occur spontaneously at Europa’s surface temperatures. If emplacement processes favor the formation of vitreous salt hydrates, they are likely to still be stable and could be an important non-ice component on Europa at present day.

title: The binary and the disk: the beauty is found within NGC3132 with JWST

description: The planetary nebula (PN) NGC3132 is a striking example of the dramatic but poorly understood, mass-loss phenomena that (1-8) Msun stars undergo during their death throes as they evolve into white dwarfs (WDs). From an analysis of JWST multiwavelength (0.9-18 micron) imaging of NGC3132, we report the discovery of an extended dust cloud around the WD central star (CS) of NGC3132, seen most prominently in the 18 micron~image, with a surface-brightness limited radial extent of &gt;~2 arcsec. We show that the A2V star located 1.7 arcsec to CS's North-East (and 0.75 kpc from Earth) is gravitationally-bound to the latter, by the detection of relative orbital angular motion of (0.24+/-0.045) deg between these stars over ~20 yr. Using aperture photometry of the CS extracted from the JWST images, together with published optical photometry and an archival UV spectrum, we have constructed the spectral-energy distribution (SED) of the CS and its extended emission over the UV to mid-IR (0.091-18 micron) range. We find that fitting the SED of the CS and the radial intensity distributions at 7.7, 12.8 and 18 micron with thermal emission from dust requires a cloud that extends to a radius of &gt;~1785 au, with a mass of ~1.3 x 10^(-2) M(Earth) and grains that are 70% silicate and 30% amorphous carbon. We propose plausible origins of the dust cloud and an evolutionary scenario in which a system of three stars -- the CS, a close low-mass companion, and a more distant A2V star -- forms a stable hierarchical triple system on the main-sequence but becomes dynamically unstable later, resulting in the spectacular mass-ejections that form the current, multipolar PN.

title: The Development and Demonstration of the Portable Acousto-optic Spectrometer for Astrobiology in Cave Environments

description: Planetary caves are desirable environments for the search for biosignatures corresponding to extant or extinct extraterrestrial life due to the protection they offer from surface-level solar radiation and ionizing particles. Near-infrared (NIR) reflectance spectroscopy is one of a multitude of techniques that, when taken together, can provide a comprehensive understanding of the geomicrobiology in planetary subsurface regions. To that end, we developed two portable NIR spectrometers that employ acousto-optic tunable filters (AOTFs) and demonstrated them in three geochemically distinct cave environments. The instruments were deployed both as stand-alone spectrometers positioned against the targets manually and as a component of an instrument payload mounted on a quadruped robot capable of vertical excursions of several meters. In situ measurements of calcium carbonates, sulfates, metal oxides, and microbial colonies and mats revealed spectral signatures that enable a distinction between the targets of interest and the underlying substrates. The ruggedness and portability of the instruments, and their low size, weight, and power (SWaP), spectral agility, and their active illumination make AOTF-based spectrometers ideally suited for studies of planetary caves.

title: Resonant Diurnal Internal Tides in the North Atlantic, Part II: Modeling

description: An unconstrained global ocean simulation for 2020 supports past observations of diurnal internal tides by acoustic tomography during the 1991--1992 Acoustic Mid-Ocean Dynamics Experiment (AMODE) in the Western North Atlantic. Explicitly representing the tides, the simulation reproduces the functional form and resonant state of K1 and O1 internal-tide standing waves, while providing a more realistic physical picture of them. The tomographic data were used to predict the tides in 2020. Not surprisingly, the characteristics of the barotropic and internal tides of the unconstrained simulation deviate from observations. The simulated barotropic tidal currents have excessive, irregular amplitude and lead the acoustic tidal predictions by about 2 hours. While internal-tide phase coherence is apparent, the simulated internal-tide variations were irregular in amplitude and phase, unlike the observations. The tomographic tidal measurements therefore provide a quantitative benchmark for improved model representation of tides, internal tides, and dissipation.

title: A Coupled Ground Heat Flux-Surface Energy Balance Model of Evaporation Using Thermal Remote Sensing Observations

description: One of the major undetermined problems in evaporation(ET) retrieval using thermal infrared remote sensingis the lack of a physically based ground heat flux (G) modeland its integration within the surface energy balance (SEB)equation. Here, we present a novel approach based on couplinga thermal inertia (TI)-based mechanistic G model withan analytical surface energy balance model, Surface TemperatureInitiated Closure (STIC, version STIC1.2). The coupledmodel is named STIC-TI. The model is driven by noon–night (13:30 and 01:30TS4 ) land surface temperature, surfacealbedo, and a vegetation index from MODIS Aqua inconjunction with a clear-sky net radiation sub-model and ancillarymeteorological information. SEB flux estimates fromSTIC-TI were evaluated with respect to the in situ fluxesfrom eddy covariance measurements in diverse ecosystemsof contrasting aridity in both the Northern Hemisphere andSouthern Hemisphere. Sensitivity analysis revealed substantialsensitivity of STIC-TI-derived fluxes due to the land surfacetemperature uncertainty. An evaluation of noontime G(Gi) estimates showed 12 %–21% error across six flux towersites, and a comparison between STIC-TI versus empiricalG models also revealed the substantially better performanceof the former. While the instantaneous noontime net radiation(RNi) and latent heat flux (LEi) were overestimated(15% and 25 %), sensible heat flux (Hi) was underestimated(22 %). Overestimation (underestimation) of LEi (Hi) wasassociated with the overestimation of net available energy(RNi 􀀀Gi) and use of unclosed SEB flux measurements inLEi (Hi) validation. The mean percent deviations in Gi andHi estimates were found to be strongly correlated with satel-lite day–night view angle difference in parabolic and linearpattern, and a relatively weak correlation was found betweenday–night view angle difference versus LEi deviation.Findings from this parameter-sparse coupled G–ET modelcan make a valuable contribution to mapping and monitor-ing the spatiotemporal variability of ecosystem water stressand evaporation using noon–night thermal infrared observationsfrom future Earth observation satellite missions such asTRISHNA, LSTM, and SBG.

title: Model-based Retrieval of Forest Parameters from Sentinel-1 Coherence and Backscatter Time-series

description: This paper describes a model-based algorithm for estimating tree height and other bio-physical land parameters from time-series of synthetic aperture radar interferometric coherence and backscatter supported by sparse lidar data. The random-motion-over-ground model (RMoG) is extended to timeseries and revisited to capture the short- and long-term temporal coherence variability caused by motion of the scatterers and changes in the soil and canopy backscatter. The proposed retrieval algorithm estimates first the spatially slow-varying RMoG model parameters using sparse lidar data, and subsequently the spatially fast-varying model parameters such as tree height. The recently-published global Sentinel-1 interferometric coherence and backscatter data set and sparse spaceborne GEDI lidar data are used to illustrate the algorithm. Results obtained for a small region over Spain show that the temporal coherence and backscatter time-series have the potential to be used for global, model-based land parameter estimation
