title: Transmission spectroscopy of the lowest-density gas giant: metals and a potential extended outflow in HAT-P-67b

description: Extremely low-density exoplanets are tantalizing targets for atmospheric characterization because of their promisingly large signals in transmission spectroscopy. We present the first analysis of the atmosphere of the lowest-density gas giant currently known, HAT-P-67b. This inflated Saturn-mass exoplanet sits at the boundary between hot and ultrahot gas giants, where thermal dissociation of molecules begins to dominate atmospheric composition. We observed a transit of HAT-P-67b at high spectral resolution with CARMENES and searched for atomic and molecular species using crosscorrelation and likelihood mapping. Furthermore, we explored potential atmospheric escape by targeting Hα and the metastable helium line. We detect Ca II and Na I with significances of 13.2 and 4.6 σ, respectively. Unlike in several ultrahot Jupiters, we do not measure a day-to-night wind. The large line depths of Ca II suggest that the upper atmosphere may be more ionized than models predict. We detect strong variability in Hα and the helium triplet during the observations. These signals suggest the possible presence of an extended planetary outflow that causes an early ingress and late egress. In the averaged transmission spectrum, we measure redshifted absorption at the ∼ 3.8% and ∼ 4.5% level in the Hα and He I triplet lines, respectively. From an isothermal Parker wind model, we derive a mass loss rate of M˙ ∼ 1013 g s−1 and an outflow temperature of T ∼ 9900 K. However, due to the lack of a longer out-of-transit baseline in our data, additional observations are needed to rule out stellar variability as the source of the Hα and He signals.

title: Forecasting landslides using community detection on geophysical satellite data

description: As a result of extreme weather conditions, such as heavy precipitation, natural hillslopes can fail dramatically; these slope failures can occur on a dry day due to time lags between rainfall and pore-water pressure change at depth, or even after days to years of slow-motion. While the prefailure deformation is sometimes apparent in retrospect, it remains challenging to predict the sudden transition from gradual deformation (creep) to runaway failure. We use a network science method { multilayer modularity optimization { to investigate the spatiotemporal patterns of deformation in a region near the 2017 Mud Creek, California landslide. We transform satellite radar data from the study site into a spatially-embedded network in which the nodes are patches of ground and the edges connect the nearest neighbors, with a series of layers representing consecutive transits of the satellite. Each edge is weighted by the product of the local slope (susceptibility to failure) measured from a digital elevation model and ground surface deformation (current rheological state) from interferometric synthetic aperture radar (InSAR). We use multilayer modularity optimization to identify strongly-connected clusters of nodes (communities) and are able to identify both the location of Mud Creek and nearby creeping landslides which have not yet failed. We develop a metric, community persistence, to quantify patterns of ground deformation leading up to failure, and nd that this metric increases from a baseline value in the weeks leading up to Mud Creek's failure. These methods promise as a technique for highlighting regions at risk of catastrophic failure

title: A MEMS MICROVALVE FOR THE SPACECRAFT ATMOSPHERE MONITOR (SAM) INSTRUMENT

description: This paper reports on the design, simulation, and characterization of a MEMS gas microvalve (MV) intended to be used as part of the Spacecraft Atmosphere Monitor (SAM) instrument, a highly miniaturized gas chromatograph mass spectrometer (GC-MS) for the International Space Station (ISS). All performance requirements at the system level were considered for flow and pull-in voltage simulations, and multiple tradeoffs were considered to ensure successful operation of SAM. Results of a selection of three MV generations are presented and discussed, including our latest generation, Rev ψ, that meets all the key performance requirements with significant margin with a measured sampling flow above 0.34 sccm and pull-in voltage below 255 V for a current lower than 1 μA.

title: Vision-based Distributed Pose Estimation using a Spacecraft Constellation

description: In this paper, we present a simulation framework and consensus algorithms to track the pose (position and attitude) of an uncooperative/defunct spacecraft (Target spacecraft) using a fleet of small spacecraft (Ego spacecraft) in Low Earth Orbit (LEO). Since it is not possible to put traditional active sensors (like differential GPS, inter-satellite communication) on the uncooperative/ defunct Target spacecraft, the fleet of Ego spacecraft have to rely on cameras and inter-spacecraft communication among themselves to estimate the relative pose of the Target spacecraft.

title: 94GHZ RF-PHOTONICS RECEIVER FOR COMPACT SPACEBORNE RADARS

description: We introduce a novel RF-photonics receiver concept for high performance ultra-compact 94~GHz radars optimized for cloud and precipitation profiling, planetary boundary layer observations, altimetry and surface scattering measurements. The new receiver architecture offers compelling advantages over traditional electronic implementations, including reduced size, weight and power (SWaP), lower system noise leading to improved sensitivity and a W-band LO with ultra-low phase noise to enable long pulse lengths needed for most compact spaceborne radar systems.

title: Validation of Hall2De simulations with anomalous ion heating in the pole region of a magnetically shielded Hall thruster

description: Magnetic shielding in Hall thrusters has been shown to protect the discharge channel walls from ion sputtering thereby eliminating this process as a failure mode. Some low yet measurable erosion has been observed however on surfaces along the side of such thrusters facing the near-plume plasma. With measured rates below 100 μm/kh, NASA’s Hall Effect Rocket with Magnetic Shielding (HERMeS) has featured a low sputtering yield cover of a few millimeters in thickness to protect the front magnetic poles from erosion. In recent work, we argued that anomalous ion heating due to lower hybrid instabilities can play a major role in the erosion of these surfaces. We implement in the 2-D axisymmetric code Hall2De a phenomenological model that accounts for these anomalous effects in the plume region of the thruster. We extract ion velocity distribution functions from the simulations and compare them with those measured by laser-induced fluorescence, showing that the model significantly improves the agreement between the two in the vicinity of the poles. We also show that the simulations predict the measured erosion rates during wear tests within the uncertainty of the measurements. We finally apply the model without modifications to multiple operating conditions, maintaining similar levels of agreement with the experimental measurements.

title: Field Application of a High-Power Density Electromagnetic Energy Harvester to Power Wireless Sensors in Transportation Infrastructures

description: Traffic-induced vibration of transportation infrastructures is a reliable source of kinetic energy, which can be harvested to power conventional monitoring sensors and peripherals installed on bridges, thereby reducing some dependence on non-renewable energy. The highway statistics shows that the average daily vehicles miles travelled in the US is more than 5 billion. This is a massive source of kinetic energy that lies unused in the national transportation network. This study focuses on the design and field testing of a high-power density electromagnetic energy harvester (EMEH) to convert such a kinetic energy into electrical energy for powering ubiquitous sensors installed on transportation infrastructures. The principal investigators have been investigating the design of the EMEH using analytical and finite element simulations, as well as, its laboratory prototype fabrication and testing in the first phase. The proposed EMEH utilizes the innovative concept of creating planar array of large number of small permanent magnets through certain optimization criteria to achieve strong and focused magnetic field in a particular orientation. The proposed EMEH has a compact design, such that it can be integrated into the power circuit of wireless sensor nodes (WSNs) and installed at suitable part of a transportation infrastructure without elaborate wiring. It is capable of continuously charging the rechargeable battery of a WSN, thereby extending the lifespan of the monitoring system, almost, indefinitely. For the next phase of this research, the principal investigators propose the development and field implementation of a larger scale and more compact version of the EMEH with a minimum of 500 mW output power to be installed on selected transportation infrastructures for the evaluation of its energy harvesting efficiency and capability to derive different types of monitoring sensors and peripherals. Three different highway bridges with different fundamental frequencies, ideally between 2Hz to 8Hz, will be selected for the field testing of the EMEH. An acceleration sensor will be used to record the traffic-induced vibration of each bridge during a normal daily traffic that after signal processing is used to measure the fundamental frequency of that bridge. The dynamic characteristics of the proposed EMEH (i.e. tip mass and spring stiffness) will be modified to put it into a resonant condition with the bridge by matching their natural frequencies. The output power will be monitored and used to continuously charge a rechargeable battery powering a wireless sensor. The focus is on the feasibility of the proposed EMEH to power sensors that are used to regularly monitor the structural integrity of materials and components of highway bridges such as acceleration and temperature sensors.

title: Permafrost_carbon_Supplementary_Data.xlsx

description: The datasets presented are primarily data syntheses from the literature of carbon stocks and fluxes from the northern permafrost region from the Last Glacial Maximum (LGM; 21,000 years before present) to present. Deglacial carbon stocks were estimated from the northern permafrost zone by subtracting estimates of carbon losses from LGM values of different systems (e.g., shelf/subsea, thermokarst lakes, peatland, yedoma, subglacial) reported in the literature. Values reported for present day were compiled from the literature. Carbon losses from permafrost thaw are reported as petagrams CO<sub>2</sub>-C (fraction of carbon from CO<sub>2</sub>) per degree Celsius (Pg CO<sub>2</sub>-C ºC<sup>-1</sup>), petagrams CH<sub>4</sub>-C (fraction of carbon from CH4) per degree Celsius, and total petagrams carbon per degree Celsius (Pg CH4-C ºC<sup>-1</sup>) where possible. Where values were not reported as Pg C ºC<sup>-1</sup> in the literature, fluxes were divided by the change in temperature for the time period using deglacial temperature changes from the literature.
