title: The β Pictoris b Hill Sphere Transit Campaign II. Searching for the signatures of the β Pictoris exoplanets through time delay analysis of the δ Scuti pulsations

description: Context. The β Pictoris system is the closest known stellar system with directly imaged gas giant planets, with the inner planet, β Pictoris c also indirectly detected with radial velocity, an edge-on circumstellar disk, and evidence for falling evaporating bodies and transiting exocomets. The star is a known δ Scuti pulsator, and the long term stability of these pulsations opens up the possibility of indirectly detecting the gas giant planets through time delays of these pulsations due to a varying light travel time. Aims. We search for phase shifts in the δ Scuti pulsations consistent with the known planets β Pictoris b and c and carry out an analysis of the stellar pulsations within β Pictoris over a multi-year timescale. Methods. We use the photometric data collected by the BRITE-Constellation, bRing, ASTEP and TESS to derive a list of the strongest significant δ Scuti pulsations. We carry out an analysis with the open-source python package maelstrom to study the stability of the pulsational modes of β Pictoris to determine the long term trends in the pulsations seen. Results. We do not detect the expected signal for β Pictoris b or β Pictoris c. The expected time delay is 6 seconds for β Pictoris c and 24 seconds for β Pictoris b. In the absence of systematic drifts of pulsational modes in the star, our combined sensitivity is SZ: XXX seconds. CHECK With simulations we determine that the photometric noise in all the combined data sets cannot reach the sensitivity needed to detect the expected timing drift. An analysis of the pulsational modes of β Pictoris using maelstrom shows that the modes themselves drift on a timescale of a year, fundamentally limiting our ability to detect exoplanets around β Pictoris using the pulsation drift technique.

title: Why are (almost) all the protostellar outflows aligned in Serpens Main?

description: We present deep 1.4-4.8 μm JWST-NIRCam imaging of the Serpens Main star-forming region and 12 identify 20 candidate protostellar outflows, most with bipolar structure and identified driving sources. 13 The outflow position angles (PAs) are strongly correlated, and aligned within ±24◦ of the major 14 axis of the Serpens filament. These orientations are further aligned with the angular momentum 15 vectors of the two disk shadows in this region. We estimate that the probability of this number 16 of young stars being co-aligned if sampled from a uniform PA distribution is 10−4. This in turn 17 suggests that the aligned protostars, which seem to be at similar evolutionary stages based on their 18 outflow dynamics, formed at similar times with a similar spin inherited from a local cloud filament. 19 Further, there is tentative evidence for a systematic change in average position angle between the 20 north-western and south-eastern cluster, as well as increased scatter in the PAs of the south-eastern 21 protostars. SOFIA-HAWC+ archival dust polarization observations of Serpens Main at 154 and 214 μm 22 are perpendicular to the dominant jet orientation in NW region in particular. We measure 23 and locate shock knots and edges for all of the outflows and provide an identifying catalog. We suggest 24 that Serpens main is a cluster that formed from an isolated filament, and due to its youth retains its 25 primordial outflow alignment.

title: Analytical Methods Used in the Design of Thermal Toolbox Elements for Extreme Environments

description: This paper describes the analytical methods used in the design/development of new thermal toolbox elements for science payload operation/survival in extreme environments. These new thermal tools were developed as a result of five JPL projects (PALETTE, ARTEMIS, ROD-TSW, ES-ROD-TSW, and mini-ROD-TSW) and include thermally-switched enclosures (TSE), parabolic reflector radiators (PRR), spacerless multilayer insulation (SMLI), low conductance thermal isolators (LCTI), 3 types of reverse-operation DTE thermal switches (ROD-TSW), miniaturized loop heat pipes (mini-LHP), Vectran tension cables (VTC), and wire heat leak minimization (WHLM) techniques. The analytical methods are used to predict key performance parameters (KPPs) associated with each thermal tool. The KPPs include TSE lunar night heat loss flux (qLOSS), PRR lunar noon radiative sink temperature (TS), SMLI effective emissivity (*), LCTI thermal conductance (G), ROD-TSW/mini-LHP ON/OFF behavior, VTC structure stiffness and frequency (k and ), and WHLM heat loss. The paper also describes thermal toolbox mission infusion status.

title: Cathode Species Contributions to Hall Thruster Plume Dynamics

description: By operating a Hall thruster with xenon flow through the cathode and krypton flow through the anode, we can spectroscopically distinguish between the cathode and ion emis- sions in the thruster plume. With narrow band-pass filters for well isolated neutral and ion emission lines for both xenon and krypton, we can image cathode neutral atoms or ions separately for this combination of gases. This imaging has revealed a non-uniform distribu- tion of cathode neutrals that changes with different anode discharge conditions, magnetic filed configurations, and facility base pressures. We also observe correlations between the strength of cathode-to-thruster coupling and discharge current oscillations, indicating the role of cathode interactions with thruster performance.

title: MoonLITE: a CLPS-delivered NASA Astrophysics Pioneers lunar optical interferometer for sensitive, milliarcsecond observing

description: MoonLITE (Moon Lunar InTerferometry Explorer) is a submitted Astrophysics Pioneers proposal to develop, build, fly, and operate the first separated-aperture optical interferometer in space, delivering sub-milliarcsecond science results. MoonLITE will leverage the NAS Commercial Lunar Payload Service (CLPS) to deliver an optical interferometer to the lunar surface, enabling unprecedented discovery power by combining high spatial resolution from optical interferometry with deep sensitivity from the stability of the lunar surface. Following landing, the CLPS-provided rover will deploy the pre-loaded MoonLITE outboard optical telescope 100 meters from the lander’s inboard telescope, establishing a two-element interferometric observatory with a single deployment. MoonLITE will observe targets as faint as 17th magnitude in the visible, exceeding ground-based interferometric sensitivity by many magnitudes, and surpassing space-based optical systems resolution by a factor of 50×. The capabilities of MoonLITE open a unique discovery space that includes (1) direct size measurements of the smallest, coolest stars and substellar brown dwarfs, (2) searches for close-in stellar companions orbiting exoplanethosting stars that could confound our understanding and characterization of the frequency of Earth-like planets, (3) direct size measurements of young stellar objects and characterization of the terrestrial planet-forming regions of these young stars, (4) measurements of the inner regions and binary fraction of active galactic nuclei, and (5) a probe of the very nature of spacetime foam itself. A portion of the observing time will also be made available to the broader community via a guest observer program. MoonLITE takes advantage of the CLPS opportunity to place an interferometer in space on a stable platform – the lunar surface – and delivers an unprecedented combination of sensitivity and angular resolution at the remarkably affordable cost point of Pioneers.

title: Evaluation of PRISMA products over snow in the Alps and Antarctica

description: PRISMA is a hyperspectral satellite mission launched by the Italian Space Agency (ASI) in April 2019. The mission is designed to collect data at global scale for a variety of applications, including those related to the cryosphere. This study presents an evaluation of PRISMA Level 1 (L1) and Level 2 (L2D) products for different snow conditions. To the aim, PRISMA data were collected at three sites: two in the Western European Alps (Torgnon and Plateau Rosa) and one in East Antarctica (Nansen Ice Shelf). PRISMA data were acquired contemporary to both field measurements and Sentinel-2 data. Simulated Top of the Atmosphere (TOA) radiance data were then compared to L1 PRISMA and Sentinel-2 TOA radiance. Bottom Of Atmosphere (BOA) reflectance from PRISMA L2D and Sentinel-2 L2A data were then evaluated by direct comparison with field data. Both TOA radiance and BOA reflectance PRISMA products were generally in good agreement with field data, showing a Mean Absolute Difference (MAD) lower than 5%. L1 PRISMA TOA radiance products resulted in higher MAD for the site of Torgnon, which features the highest topographic complexity within the investigated areas. In Plateau Rosa we obtained the best comparison between PRISMA L2D reflectance data and in situ measurements, with MAD values lower than 5 % for the 400-900nm range. The Nansen Ice Shelf instead resulted in MAD values &lt;10% between PRISMA L2D and field data, while Sentinel-2 BOA reflectance showed higher values than other data sources.

title: Shape Optimization of Pin Fin Array in a Cooling Channel Using Genetic Algorithm and Machine Learning

description: This article reports the optimization of pin fin shape using a genetic algorithm (GA) coupled either to a machine learning (ML) model or a computational fluid dynamics (CFD) model. The ML model evaluates the temperature and pressure induced by the fins with various shapes within a second and allows us to replace the time-consuming CFD simulations during the design stage. The optimization is conducted for various Reynolds numbers in the range of 3000 - 12000 and identifies a funnel-shaped fin that enhances the heat transfer coefficient by 20% without an apparent increase of pressure drop as compared to the standard cylindrical pin fins. The funnel-shaped fin outperforms other conventional fins of elliptical, cubic, and drop shapes that induce a similar level of pressure drops. This work demonstrates the potential of ML-based optimization in searching unexplored shapes of heat transfer systems with superior performance.

title: The SPHEREx instrument optical integration and testing campaign overview

description: Slated for launch in 2025, SPHEREx will be NASA’s next astrophysics explorer mission. Optimized to meet rigorous requirements to precisely map the Universe’s large scale structure, produce deep maps of the diffuse extragalactic background, and to survey the Milky Way’s biogenic ice content, the SPHEREx telescope’s wide-field optical design utilizes a series of custom near infrared linear variable filters to survey the entire sky spectroscopically. This unique instrument has now completed its construction phase and is fully assembled for flight. To precisely focus and calibrate the optical and spectroscopic properties of SPHEREx, a custom optical-cryogenic facility was developed and commissioned. In this overview, we describe the implementation of the recently completed instrument integration and testing campaign, delivering a well characterized imaging spectrometer to be integrated with the rest of the observatory.

title: Ion-Neutral Population and Electron Temperature Phasing in the Hall Thruster Breathing Mode

description: This study investigates the breathing mode, a crucial oscillation in Hall thrusters im- pacting their efficiency and stability. Among breathing mode models, a relatively simple 0-D model, the predator-prey model, explains the breathing mode as an interaction be- tween neutral atoms ions. Despite its significance, the predator-prey relationship between ions and neutral atoms theorized to drive this mode has lacked concrete diagnostic evi- dence. The FastOES diagnostic is employed to simultaneously measure characteristics of the neutral and ion populations through their respective emissions. The observed phase difference between Xe I and Xe II emissions is consistent with the expected phase difference between neutral and ion populations according to the predator-prey model. The FastOES diagnostic is also used to measure the time-resolved electron temperature, revealing signif- icant oscillations and a consistent out-of-phase relationship between the discharge current and electron temperature.

title: Lunar Communications Using Relays

description: Employing lunar orbiting relays for Earth-Moon communications offers several advantages that include the ability to communicate from the far side of the Moon, improved link conditions for the near-side communications and providing lunar-surface-to-lunar-surface connectivity. Due to the recent surge of interest to explore the Moon robotically and possibly develop human colonies, industry has responded by making plans to provide communication relay services for the Moon. Similarly, NASA is also investing in lunar surface radios that can be readily obtained by future users for lunar relay communications. The proposed relay arrangements vary from single-satellite networks to multi-satellite infrastructures. This paper will review the proposed relay systems and will discuss a user communication terminal that is currently being developed via NASA support. A discussion of the target capabilities that are presently being developed will be provided. Moreover, the likely technical approaches that will be utilized to enable lunar communications will be addressed. These will include physical layer technologies as well as algorithms and protocols that may be adopted. A brief discussion of standards will also be offered.

title: TM EDMR based magnetometry: A novel tandem (de-)modulation technique enhancing the electrical readout of the spin-dependent recombination current in SiC JFETs

description: A spin readout based on electrically detected magnetic resonance (EDMR) holds potential to bring quantum application into miniaturized devices e.g. as a magnetometer, yet sensitivity has remained a challenge. In this study, we present a novel tandem (de-)modulation technique based on a combination of magnetic field and radio frequency modulation. By enabling higher demodulation frequencies to avoid 1/f-noise, enhancing self-calibration capabilities, and eliminating background signals by three orders of magnitude, this technique represents a significant advancement in the field ofEDMR-based sensors. This novel approach paves the way for EDMR being the ideal candidate for ultra-sensitive magnetometry at ambient conditions without any optical components, which brings it one step closer to a chip-based quantum sensor for future applications.

title: Psyche Mission Transition to Operations IEPC-2024-225 - final PDF

description: The Psyche spacecraft launched on October 13, 2023 on a mission to rendezvous and orbit the main belt asteroid 16 Psyche. During the initial checkout phase and the subsequent interplanetary cruise (ongoing), electric propulsion thrusting using SPT-140 Hall thrusters represents the first time Hall thrusters have been used in interplanetary space. Orbital operations, starting in 2029, will include four distinct science orbits interspersed with electric propulsion orbit transfers. The pre-launch mission plan has proven resilient to information learned during initial operations, but the operations team has updated the plan in response to information learned so far during mission operations. This paper provides an updated summary of the Psyche mission plan, including changes due to the one-year delay of launch from October 2022 to October 2023 and significant adjustments made in the final months of development and the first half year of operations. Furthermore, this paper highlights the planning complexities of electric propulsion activities and offers lessons learned for future low thrust missions.

title: Does Timing of Metastatic Presentation (Synchronous versus Asynchronous) Affect Outcome in Advanced Urothelial Carcinoma?

description: Bladder cancer is the most common cancer in the urinary system with an estimated 549,393 new cases and 199,922 deaths worldwide in 2018. Urothelial carcinoma is the most common histological form of bladder cancer that originates from the inner lining of the urinary bladder and accounts for more than 90% of all cases. Approximately 10% cases present with locally advanced cancers (cancers that has spread beyond the original location but is still confined to near by organs) or metastatic cancers (cancers that has spread to distant organs such as lung, bones) at diagnosis. Prognosis is poor for these patients and less than 15% survive beyond 5 years at diagnosis. While metastatic urothelial carcinoma is considered incurable, advent of immunotherapy (a type of cancer treatment that utilized the body’s natural defenses to target cancer cells) has ushered a new era in the management of these patients. 

Timing of metastatic presentation has been shown to be prognostic and predictive of treatment effect in cancers of prostate and kidney. It is usually seen that patients who present with metastatic disease at the time of diagnosis has poor outcome compared to those with metastatic disease at the time of recurrence. However, it is unclear if such correlation exists between timing of metastatic presentation and outcome and treatment response in metastatic urothelial carcinoma. We propose a pooled analysis of 6 clinical trials that investigated the safety and utility of immunotherapy in metastatic urothelial carcinoma. We will collect data about baseline characteristics including timing of metastatic presentation, treatment response, and outcome from individual patients in all the studies. Subsequently we will determine if the outcome of patients with de novo urothelial carcinoma (i.e., those who present with metastatic disease at the time of diagnosis) was significantly different from outcome of patients who presented with recurrent metastatic urothelial carcinoma (who presented with metastatic disease at recurrence). Similarly we will also determine if the outcome with immunotherapy differed among patients with exposure to prior surgery or radiation therapy for urothelial carcinoma compared to those without exposure to prior surgery or radiation therapy.
