title: Demonstrating Autonomy for Complex Space Missions: An Autonomy Software Prototype for the Europa Lander Mission

description: There is a desire for robotic spacecraft to perform exploration in unknown, dynamic environments. The Europa Lander Mission Concept is one such mission that needs to deal with an extremely limited lifetime and energy supply, intermittent communications with long blackouts, face numerous environmental dangers, and ultimately take place too far from Earth to rely on human control. No missions to date have operated with the required level of autonomy and under the same level of communication constraints, uncertainty, and mission concept complexity as this mission. As a result, the viability of the autonomy must be demonstrated before it will be trusted with mission critical planning. In this paper, we present an autonomous software prototype which can demonstrate and test the ability of different planners and executives to carry out complex, science-centric missions with limited interventions from humans. The prototype uses a hierarchical utility model that is used to maximize both the amount of expected science return as well as the number of mission objectives imposed by the ground. We demonstrate how this system handles some of the autonomous tasks expected of complex space missions such as decision making, in-situ data acquisition and analysis, data prioritization, resource management, and failure response handling in both simulation and on actual hardware. Through several scenario-based experiments we show how different planners and executives can meet the challenges of the Europa Lander Mission Concept. We also demonstrate that this system can be used in concert with a hardware prototype for autonomy field tests.

title: Strong Evidence of Heterogeneous Processing on Stratospheric Sulfate Aerosol in the Extrapolar Southern Hemisphere Following the 2022 Hunga Tonga-Hunga Ha’apai Eruption

description: The January 2022 eruption of Hunga Tonga-Hunga Ha’apai (HT-HH) caused the largestenhancement in stratospheric aerosol loading in decades and produced an unprecedentedenhancement in stratospheric water vapor, leading to strong stratospheric cooling thatin turn induced changes in the large-scale circulation. Here we use satellite measurementsof gas-phase constituents together with aerosol extinction to investigate the extent towhich the thick aerosol, excess moisture, and strong cooling enabled heterogeneous chem-ical processing. In the southern tropics, unambiguous signatures of substantial chlorineand nitrogen repartitioning appear over a broad vertical domain almost immediately af-ter the eruption, with depletion of N2O5, NOx, and HCl accompanied by enhancementof HNO3, ClO, and ClONO2. After initially rising steeply, HNO3 and ClO plateau, main-taining fairly constant abundances for several months. These patterns are consistent withthe saturation of N2O5 hydrolysis, suggesting that this reaction is the primary mecha-nism for the observed composition changes. The southern midlatitudes and subtropicsshow similar but weaker enhancements in ClO and ClONO2. In those regions, however,effects of anomalous transport dominate the evolution of HNO3 and HCl, obscuring thesigns of heterogeneous processing. Perturbations in chlorine species are considerably weakerthan those measured in the southern midlatitude stratosphere in 2020 following the Aus-tralian New Year’s fires. The moderate HT-HH-induced enhancements in reactive chlo-rine seen throughout the southern middle and low-latitude stratosphere, far smaller thanthose in typical winter polar vortices, do not lead to appreciable chemical ozone loss; rather,extrapolar lower-stratospheric ozone remains primarily controlled by dynamical processes

title: Acetonyl peroxy and hydro peroxy self- and cross- reactions: Temperature-dependent kinetic parameters, branching fractions, and chaperone effects

description: The temperature dependent kinetic parameters, branching fractions, and chaperone effects of the self- and cross-reactions between acetonyl peroxy (CH3C(O)CH2O2) and hydro peroxy (HO2) have been studied using pulsed laser photolysis coupled with infrared (IR) wavelength modulation spectroscopy and ultraviolet absorption (UVA) spectroscopy. Two IR lasers simultaneously monitored HO2 and hydroxyl (OH) while UVA measurements monitored CH3C(O)CH2O2. For the CH3C(O)CH2O2 self-reaction, the rate parameters were determined to be A = (〖1.5〗_(-0.3)^(+0.4))  10-13 and Ea/R = 996  334 K-1 and the branching fraction to the alkoxy channel, k2b /k2, showed an inverse temperature dependence following the expression, k2b /k2 = (2.27  0.62)  [(6.35  2.06)  10-3] T(K). The rate parameters for the reaction between CH3C(O)CH2O2 and HO2 were determined to be A = (〖3.4〗_(-1.5)^(+2.5))  10-13 and Ea/R = 547  415 K-1 for the hydroperoxide product channel and A = (6.23 〖6.23〗_(-4.4)^(+15.3))  10-17 and Ea/R = 3100  870 K-1 for the OH product channel. The branching fraction for the OH channel, k1b /k1, follows the temperature-dependent expression, k1b /k1 = (3.27  0.51)  (9.6  1.7  10-3) T(K). Determination of these parameters required an extensive reaction kinetics model which included a re-evaluation of the temperature dependence of the HO2 self-reaction chaperone enhancement parameters due to the methanol-hydroperoxy complex. The 2nd Law thermodynamic parameters for KP,M for the formation of the complex were found to be ∆rH_(250 K)^° = −38.6 ± 3.3 kJ mol-1 and ∆rS_(250 K)^° = −110.5 ± 13.2 J mol-1 K-1, with 3rd Law analysis yielding ∆rH_(250 K)^° = −37.5 ± 0.25 kJ mol-. The HO2 self-reaction rate coefficient was determined to be k_4=(〖3.34〗_(-0.80)^(+1.04) )×〖10〗^(-13) exp⁡[(507±76)/T]〖 cm〗^3 〖 molecule〗^(-1) 〖 s〗^(-1) with the enhancement factor k_(4,M)^''=(〖2.7〗_(-1.7)^(+4.7) )×〖10〗^(-36) exp⁡[(4700 ± 255)/T] 〖 cm〗^6 〖 molecule〗^(-2) 〖 s〗^(-1), proportional to [CH3OH], over T = 220–280 K. The equivalent chaperone enhancement parameter for the acetone-hydroperoxy complex was also required and determined to be k_(4,A)^'' = (5.0 × 10−38 – 1.4 × 10−41) exp[(7396 ± 1172)/T] cm6 molecule−2 s−1, proportional to [CH3C(O)CH3], over T = 270 – 296 K. From these parameters the rate coefficients for the reactions between HO2 and the respective complexes over the given temperature ranges can be estimated: for HO2·CH3OH, k12 = [(1.72 ± 0.050) × 10-11] exp [(314 ± 7.2)/T] cm3 molecule-1 s-1 and for HO2·CH3C(O)CH3, k15 = [(7.9 ± 0.72) × 10-17] exp [(3881 ± 25)/T] cm3 molecule-1 s-1. Lastly, an estimate of the rate coefficient for the HO2·CH3OH self-reaction was also determined to be k13 = (1.3 ± 0.45) × 10-10 cm3 molecule-1 s-1.

title: Spatial Distribution of Glycine and Aspartic Acid in Frozen Enceladus Brines Relevant to Enceladus

description: Saturn’s moon Enceladus harbors a global, subsurface liquid ocean beneath an icy crust that actively erupts water jets from cracks in its south pole. Data returned from the Cassini mission have identified the presence of salts and organic matter within these ejected plume particles. Such combinations of water, organics, and salts present rather complex chemical environments that may hold direct implications for habitability. In particular, the fundamental behavior of organics in frozen brine systems upon exposure to relevant Enceladus surface conditions is an important aspect that has not been explored to date (e.g. how they organize and partition relative to the salt minerals within the ice matrix). The present work investigates this topic by characterizing the spatial distribution of two representative amino acids (glycine and aspartic acid) in a putative frozen Enceladus brine containing sodium, chloride, and carbonate ions via micro-Raman imaging. The results show that both amino acid-bearing solutions undergo some degree of vitrification upon flash freezing, especially for the chloride salt and glycine. Subsequent annealing of the vitreous samples reveals preferential association of the amino acids with crystalline salt hydrates rather than with water ice. The highest correlation is found between aspartic acid and natron (Na2CO3•10H2O), while glycine and water ice exhibit the lowest. This suggests that solute-solute interaction likely dominates in these frozen systems, especially if charged species are present. The results imply that salt-rich ice particles can serve as concentrators of organic biomarkers, enhancing their potential for detection from remote sensing or in situ measurements.

title: Projections of Large-Scale Atmospheric Circulation Patterns and Associated Temperature and Precipitation Over the Pacific Northwest Using CMIP6 Models

description: Climate model projections of 500 hPa geopotential height (Z500) patterns, their frequency, and associated temperature and precipitation anomalies under a high-end global warming scenario are assessed for the Pacific Northwest of North America for the end of the 21st century. Simulations are from models contributing to the 6th phase of the Coupled Model Intercomparison Project (CMIP6) and Z500 patterns are identified using the self-organizing maps approach. Models project a general reduction in the magnitude of Z500 anomalies in summer. The largest temperature increases in winter are found for patterns historically associated with anomalously cold weather and in northern latitudes, while the largest temperature increases in summer are found in inland areas of the Pacific Northwest. Precipitation is found to generally increase across all seasons and patterns, however some historically wet summer patterns are projected to become significantly drier. Significant changes in pattern frequencies are found in summer, with a general decrease in frequency of highly amplified Z500 anomaly patterns.

title: Decadal decrease in Los Angeles methane emissions inferred from atmospheric data is much smaller than bottom-up estimates

description: Methane, a powerful greenhouse gas, has a short atmospheric lifetime (~12 years), so that emissions reductions will have a rapid impact on climate forcing. In megacities such as Los Angeles (LA), natural gas (NG) leakage is the primary atmospheric methane source. The magnitudes and trends of fugitive NG emissions are largely unknown and need to be quantified to verify compliance with emission reduction targets. Here we use atmospheric remote sensing data to show that, in contrast to the observed global increase in methane emissions, LA area emissions decreased during 2011-2020 at a mean rate of (–1.57±0.41) %/yr. However, the NG utility calculations indicate a much larger negative emissions trend of 5.8 %/yr. The large difference between top-down and bottom-up trends reflects the uncertainties in estimating the achieved emissions reductions. Actions taken in LA can be a blueprint for COP28 and future efforts to reduce methane emissions.

title: A Review on Hypothesized Metabolic Pathways on Europa and Enceladus: Space-Flight Detection Considerations

description: Enceladus and Europa, icy moons of Saturn and Jupiter respectively, are believed to be habitable with liquid water oceans and therefore are of interest for future life detection missions and mission concepts. With the limited data from missions to these moons, many studies have sought to better constrain these conditions. With these constraints, researchers have, based on modeling and ex-perimental studies, hypothesized a number of possible metabolisms that could exist on Europa and Enceladus if these worlds host life. The most often hypothesized metabolisms are methanogenesis for Enceladus and methane oxidation / sulfate reduction on Europa. Here, we outline, review, and compare the conditions of each moon’s ocean based on modelled and mission data. We then discuss the hypothetical metabolisms that have been suggested to be present on these moons, based on laboratory studies and Earth analogs. We also detail different detection methods that could be used to detect these hypothetical metabolic reactions and make recommendations for future research and considerations for future missions.

title: Gas Sources from the Coma and Nucleus of Comet 46P/Wirtanen Observed Using ALMA

description: Gas-phase molecules in cometary atmospheres (comae) originate primarily from (1) outgassing by the nucleus, (2) sublimation of icy grains in the near-nucleus coma, and (3) coma (photo-)chemical processes. However, the majority of cometary gases observed at radio wavelengths have yet to be mapped, so their production/release mechanisms remain uncertain. Here we present observations of six molecular species towards comet 46P/Wirtanen, obtained using the Atacama Large Millime- ter/submillimeter Array (ALMA) during the comet’s unusually close (∼ 0.1 au) approach to Earth in December 2018. Interferometric maps of HCN, CH3OH, CH3CN, H2CO, CS and HNC were obtained at an unprecedented sky-projected spatial resolution of up to 25 km, enabling the nucleus and coma sources of these molecules to be accurately quantified. The HCN, CH3OH and CH3CN spatial distri- butions are consistent with the production from direct outgassing from (or very near to) the nucleus, with a significant proportion (∼ 50 %) of the observed CH3OH originating from sublimation of icy grains in the near-nucleus coma. On the other hand, H2CO, CS and HNC originate primarily from distributed coma sources. The HCN, CH3OH and HNC abundances in 46P are consistent with the average values previously observed in comets, whereas the H2CO, CH3CN and CS abundances are relatively low.

title: A Bayesian Framework for Verifying Methane Inventories and Trends With Atmospheric Methane Data

description: The 2015 Paris Climate Agreement and Global Methane Pledge formalized agreement for countries to report and reduce methane emissions to mitigate near-term climate change. Emission inventories generated through surface activity measurements are reported annually or bi-annually and evaluated periodically through a “Global Stocktake”. Emissions inverted from atmospheric data support evaluation of reported inventories, but their systematic use is stifled by spatially variable biases from prior errors combined with limited sensitivity of observations to emissions (smoothing error), as-well-as poorly characterized information content. Here, we demonstrate a Bayesian, optimal estimation (OE) algorithm for evaluating a state-of-the-art inventory (EDGAR v6.0) using satellite-based emissions from 2009 to 2018. The OE algorithm quantifies the information content (uncertainty reduction, sectoral attribution, spatial resolution) of the satellite-based emissions and disentangles the effect of smoothing error when comparing to an inventory. We find robust differences between satellite and EDGAR for total livestock, rice, and coal emissions: 14  9, 12  8, -11  6 Tg CH4/yr respectively. EDGAR and satellite agree that livestock emissions are increasing (0.25 to 1.3 Tg CH4/ yr / yr), primarily in the Indo-Pakistan region, sub-tropical Africa, and the Brazilian arc of deforestation; East Asia rice emissions are also increasing, highlighting the importance of agriculture on the atmospheric methane growth rate. In contrast, low information content for the waste and fossil emission trends confounds comparison between EDGAR and satellite; increased sampling and spatial resolution of satellite observations are therefore needed to evaluate reported changes to emissions in these sectors.

title: Characterization of volatiles evolved during vacuum sintering of lunar regolith simulants

description: This work describes an experimental vacuum setup, designed for sintering of lunar regolith simulant materials, and its application to real-time characterization and identification of volatile species, resulting from in vacuo decomposition of the non-lunar components in the materials. We carried out a thorough system characterization, highlighted critical performance aspects with respect to regolith sintering, identified the sample environment, and postulated the need for high-vacuum capabilities in light of the high gas loads, generated by the simulants. We detailed the process of identification of specific gas species (H2O, NO, H2S, CO2, SO2, SO3, HCl, HF, etc.) using mass spectrometry, and advanced their use as markers for thermally-activated processes, such as dehydration of hydrides, decomposition of major non-lunar phases (carbonates and sulfates) and lesser-represented components (nitrates, nitrides, fluorides, chlorites, etc.). Quantification of individual decomposing phases is feasible within reason despite the inherent limitations of mass spectrometry. The methods, detailed in this paper, are intended for direct comparison of lunar regolith simulants with respect to sintering applications.
