title: Discriminating between extinct and extant life detection: implications for future Mars missions

description: The search for biosignatures on Mars has been a high priority for astrobiology. The approach to detecting putative biosignatures has largely been focused on chemical analysis. However, this approach has limited the characterization of extant life, preventing differentiation between extinct and extant biosignatures. Detecting an extant Martian lifeform requires an incorporation of approaches focused on identification biological features. Identifying potential features of life, such as growth or reproduction, can contribute evidence necessary to identify extant biosignatures. While an unambiguous extant biosignature might not be possible with this these biological techniques, in conjunction with flight tested instrumentation, the combined data can provide supporting evidence to attribute a biosignature to an extinct or extant lifeform. With upcoming initiatives, such as the Mars Sample return and Mars Life Explorer, the incorporation of extant life specific analysis is paramount for the future of Mars exploration.

title: Widespread disruption of resonant chains during protoplanetary disk dispersal

description: We describe the evolution of low mass planets in a dispersing protoplanetary disk around a Solar mass star. The disk model is based on the results of Yu et al. (2023), which describes a region of the inner disk where the direction of the migration torque is outwards due to the diffusion of the stellar magnetic field into the disk and the resultant gradual increase in surface density outwards. We demonstrate that the magnetospheric rebound phase in such a disk leads to diverging orbits for double and triple planet systems, and the disruption of a high fraction of the initial resonant chains. We present simulations of three planet systems, with masses based on the observed triple planet systems observed by the Kepler satellite, within the context of this model. The final distribution of nearest neighbour period ratios provides an excellent fit to the observations, provided that the initial configurations contain a significant fraction of pairs whose period ratios are less than 2:1. The occurrence rate of planets as a function of orbital period also provides a good match to the observations, for final orbital periods P &lt; 20 days. These results suggest that the period and period ratio distributions of low mass planets are primarily set in place during the disk dispersal epoch, and may not require significant dynamical evolution thereafter.

title: Aerosol-Calibrated Matched Filter applied on retrievals of methane point source emissions over Los Angeles Basin

description: Methane, with a global warming potential roughly 80 times greater than carbon dioxide over a 20-year timeframe, plays a crucial role in global warming. Remote sensing retrieval is a pivotal methodology for identifying methane emission sources, with accuracy influenced largely by surface and atmospheric properties, including aerosols. In this study, we propose an Aerosol-Calibrated Matched Filter (ACMF) algorithm as the improvement of the Matched Filter (MF) method, incorporating an aerosol scattering correction factor to reduce the aerosol-induced bias on methane retrieval. Validating our algorithm through simulated spectra, we demonstrate that considering the aerosol scattering effect significantly reduces retrieval errors compared to traditional MF methods by an average of approximately 90%. We apply our newly developed algorithm to hyperspectral data obtained from the Airborne Visible/Infrared Imaging Spectrometer – Next Generation during the period of 2020 in the Los Angeles Basin, and focus on 11 plumes identified through case studies. Our results reveal that ACMF estimates of emission rates and inversion uncertainties exhibit an average reduction of approximately 4% compared to traditional MF, with deviation increasing with aerosol optical depth.

title: Jets from the Upper Scorpious Variable Young Star System 2MASS J16075796-2040087 Via KECK/HIRES Spectro-astrometry

description: 2MASS J16075796-2040087 is a ∼5 Myr young star in Upper Sco with evidence for accretion bursts on a timescale of about 15 days and, uncommonly for its age, outflows traced by multi-component forbidden emission lines (FELs). The accretion bursts may be triggered by a companion at ∼4.6 au. We analyze HIRES spectra optimised for spectro-astrometry to better understand the origin of the several FEL velocity components and determine whether a MHD disk wind is present. The FEL high velocity component (HVC) traces an asymmetric, bipolar jet ∼700 au long. The jet’s position angle (PA) ∼277◦ is not perpendicular to the disk. The lower-velocity emission, classified previously as a disk wind low-velocity component (LVC), is found to have more in common with the HVC and overall it is not possible to identify a MHD disk wind component. The spectro-astrometric signal of the low velocity emission resembles those of jets and its density and ionisation fraction fall into the range of HVCs. We suggest a scenario where the accretion bursts due to the close companion power the jets past the age where such activity ends around most stars. The low-velocity emission here could come from a slow jet launched near the close companion and this emission would be blended with emission from the MHD wind.

title: The Impact of Spatial Resolution on Inland Water Quality Monitoring from Space

description: Remote sensing of inland waters can provide timely and global water quality information to a wide variety of stakeholders. One of the parameters that determines the feasibility of using optical space-based instruments for monitoring inland waters is the ground resolution distance (GRD), defined as the smallest distance resolvable by the instrument from space. We assume that to analyse a body of water with optical imagery, its characteristic width must be larger than 3 times the GRD to obtain an ‘unmixed’ pixel that doesn’t contain signal from the adjacent land. Here we obtain the size distribution of river lengths, river areas, and lake areas—as a function of width—for rivers and lakes in the Western United States (US) and in Australia. We base this analysis on the Surface Water and Ocean Topography River Database (SWORD) and HydroLAKES databases, extrapolated to 5 m-wide features. We show that the fraction of river length and river area larger than a certain width increases sharply as the width decreases, indicating that even small decreases in the GRD result in significant increases in the number of bodies that can be surveyed. On the other hand, the distribution of lake areas shows a ‘knee’ at around 400 m, indicating that gains from GRDs smaller than 130 m will be modest. We found that a satellite instrument with a GRD capability of 18 m can provide coverage of 4.8% of total river lengths, 42% of total river area, and 93.8% of total lake area within the study areas. We argue that decreasing the GRD incurs penalties associated with loss of signal-to-noise, larger instrument, smaller swath, and longer revisit times.

title: Overview of First Two Years of JWST MIRI Cryocooler On-orbit Performance

description: Mid-Infrared Instrument (MIRI) is the only actively-cooled instrument on James Webb Space Telescope (JWST). Following the successful launch of the Observatory on December 25, 2021, and subsequent commissioning period, the instrument has been operating successfully, supporting a diverse program of infrared astronomy investigations. The MIRI focal plane and optical bench operate near 6K, with that temperature achieved and maintained by a hybrid four-stage Pulse Tube/Joule Thomson mechanical cryocooler. Apart from its raw cooling performance, the cryocooler meets stringent power, interface temperature and exported vibration requirements. We briefly review the MIRI Cryocooler thermal configuration and design, and present the on-orbit performance data that spans the two-year period following the instrument reaching its operational temperature on April 7, 2022. The cryocooler was one of Jet Propulsion Laboratory’s MIRI deliverables to NASA, with Northrop Grumman as a key industrial partner responsible for the overall design, build and performance.

title: The Dynamical State of the Didymos System Before and After the DART Impact

description: NASA’s Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the natural satellite of (65803) Didymos, on 2022 September 26, as a first successful test of kinetic impactor technology for deflecting a potentially hazardous object in space. The experiment resulted in a small change to the dynamical state of the Didymos system consistent with expectations and Level 1 mission requirements. In our pre-encounter paper \citep{Richardson2022}, we put forward predictions for the pre- and post-impact dynamical state of the Didymos system. Here we assess these predictions, update preliminary findings published after the impact, report on new findings related to dynamics, and provide implications for ESA's Hera mission to Didymos, scheduled for launch in 2024 with arrival in late December 2026. Pre-encounter predictions tested to date are mostly in line with observations, with the biggest surprise being the flattened appearance of Didymos compared to the radar model and the apparent pre-impact oblate shape of Dimorphos (where the expectation had been to find a prolate secondary). New findings include the fact that Dimorphos likely became prolate as a result of the impact or entered a tumbling rotation state, or both.

title: Tracking Land-Falling Atmospheric Rivers

description: Applications of the global positioning system (GPS) and other global navigation satellite systems (collectively referred to as GNSS) have become a pervasive presence for spatial awareness in the modern world. For geodetic applications, GNSS provides a global reference frame defined by the precise mm-level positions of a network of continuously monitoring stations, and the tracked orbits of the GNSS satellites (&gt;100 currently available). A typical GNSS station fields a geodetic quality GNSS receiver and antenna, a power source (e.g., solar), and a communications method (e.g., cell modems, microwave) to transfer data to a central location for analysis (Fig. 1). Regional GNSS networks have been established for a range of applications. In California, there are about 1000 GNSS stations1 that precisely map crustal movements across the transition from North American to the Pacific tectonic plates (Fig. 2), occurring over a zone several hundreds of kilometers wide. Occasional large earthquakes can displace the position of a station by more than a meter. The coordinates of these stations and their changes in time (displacements) define a statewide geodetic datum maintained by the California Spatial Reference Center (CSRC)2 and tied to the National Spatial Reference System (NSRS) defined and maintained by NOAA's National Geodetic Survey (NGS)3.

title: A Novel Surface Energy Balance Method for Thermal Inertia Studies of Terrestrial Analogs

description: Surface thermal inertia derived from satellite imagery offers a valuable tool for remotely mapping the physical structure and water content of planetary regolith. Efforts to quantify thermal inertia using surface temperatures on Earth, however, have consistently yielded large uncertainties and suffered from a lack of reproducibility. Unlike dry or airless bodies, Earth’s abundant water and dense atmosphere lead to dynamic thermophysical conditions that are a greater challenge to model than on a world like Mars. In this work, an approach was developed using field experiments to inform and fine-tune a thermophysical model of terrestrial sediment and calculate an inherent thermal inertia value with higher precision and less initial knowledge of the sediment than has previously been achieved remotely on Earth. A thermal inertia derived for a basaltic tephra site in Northern Arizona was replicated within 1% between different field seasons, demonstrating reproducibility. Model-derived values were validated in situ by two different thermophysical field probes to within 8% of the measured mean values. Analog studies such as this hold the promise of improved interpretations of surface materials on Mars, and an accurate thermal model for Earth is the key step to enabling translation between the two worlds.

title: The TESS-Keck Survey. XXII. A sub-Neptune Orbiting TOI-1437

description: Exoplanet discoveries have revealed a dramatic diversity of planet sizes across a vast array of orbital 41 architectures. Sub-Neptunes are of particular interest; due to their absence in our own solar system, 42 we rely on demographics of exoplanets to better understand their bulk composition and formation 43 scenarios. Here, we present the discovery and characterization of TOI-1437 b, a sub-Neptune with a 44 18.84 day orbit around a near-Solar analog (M⋆ = 1.10 ± 0.10 M⊙, R⋆ = 1.17 ± 0.12 R⊙). The planet 45 was detected using photometric data from the Transiting Exoplanet Survey Satellite (TESS) mission 46 and radial velocity follow-up observations were carried out as a part of the TESS-Keck Survey (TKS) 47 using both the HIRES instrument at Keck Observatory and the Levy Spectrograph on the Automated 48 Planet Finder (APF) telescope. A combined analysis of these data reveal a planet radius of Rp = 2.24 2 ± 0.23 R⊕ and a mass measurement of 49 Mp = 9.6 ± 3.9 M⊕). TOI-1437 b is one of few (∼50) known 50 transiting sub-Neptunes orbiting a solar-mass star that has a radial velocity mass measurement. As the 51 formation pathway of these worlds remains an unanswered question, the precise mass characterization 52 of TOI-1437 b may provide further insight into this class of planet.
