title: Improving tropical cyclone rapid intensification forecasts with satellite measurements of sea surface salinity and calibrated machine learning

description: Forecasting rapid intensification (RI) of tropical cyclones (TC) is a mission known for large errors. One under-researched factor that affects TC intensification is sea surface salinity (SSS), which is an important proxy for density stratification in certain ocean regions and can affect the surface enthalpy flux under a strengthening hurricane. To investigate the effects of SSS on TC RI, we use a previously built statistical model consisting of a variety of machine learning (ML) methods. A calibrator was trained on top of the ML models to correct probability forecasts. The ML model performance is improved with the addition of SSS in the Eastern North Pacific and the Caribbean subregion of the North Atlantic. Limited improvement is found in the Western North Pacific. In the Indian Ocean, SSS is also notably correlated with RI occurrence, but the TC samples are not sufficient to train ML models.

title: Extending Coverage Modeling to Voter Behavior for Spacecraft Reliability Modeling

description: Embedded computer-based systems, or digital systems, are used in applications, such as spacecraft, which require high reliability. Meeting the reliability requirements at the lowest possible cost, typically involves trade studies that aim to quantify the value of different mechanisms for obtaining high reliability. One of these mechanisms is fault tolerance, which involves the detection, location, isolation, and recovery of the system upon occurrence of a fault. The coverage parameter has been defined as the likelihood of successfully recovering from a fault that has occurred. If the fault and error handling mechanisms cannot successfully cover all the faults in the system, then the coverage factor is less than one and the system has imperfect coverage. An accurate reliability analysis of the system thus must take into consideration the coverage parameter, for systems with imperfect coverage. Methods for incorporation of the coverage parameter in system reliability analysis have been developed. These methods consider the uncovered failure of components both at the subsystem and system level. At the subsystem level, and in the context of hierarchical systems, the uncovered failure of a component can cause the failure of a given subsystem. At the systems level, the uncovered failure of a component can cause systems level failures. One of the mechanisms for including fault tolerance in the system is masking faults using voters. We propose to extend the existing methods for coverage modeling to consider the behavior of voters and their contribution to the prevention of uncovered failures. We consider that the system can have three states: successful, fail covered and fail uncovered and find the likelihood of each of these states as a function of the likelihood of the coverage parameter for each component as well as the likelihood of successful fault masking by the voter.

title: Atmospheric Escape Explains Diverse Surface Compositions of Pluto vs Sedna

description: Kuiper Belt Objects are thought to be remnants of early solar system materials, which have retained volatiles such as 〖CH〗_4 and C_2 H_6. Spectroscopic data from various sources reveals that while Pluto retains 〖CH〗_4and C_2 H_6, Sedna shows a lack of 〖CH〗_4 but an abundance of C_2 H_6, (Emery et. al 2024). We hypothesized that 〖CH〗_4, which is stable on Pluto, is able to escape from less massive Sedna. Sufficiently rapidly to be depleted over the age of the solar system while C_2 H_6 has been retained due to its larger molecular mass. Utilizing models for Jeans escape and hydrodynamic escape, as appropriate for a given mass of object and of escaping species, we analyzed the stability and escape rates of 〖CH〗_4 and C_2 H_6 on both Pluto and Sedna. We explored a wide range of masses of Sedna, ranging from ½ to ⅒ the mass of Pluto. We also tested three different abundances of 〖CH〗_4 and C_2 H_6 using measured values from Comet 67-P, and Enceladus, and an upper limit assuming clathrate hydrate. We tested these abundances for two different outgassing rates from the interior, 10% and 100%. We find that 〖CH〗_4 remains stable on Pluto, but escapes from Sedna due to its lower mass, whereas C_2 H_6 remains stable when using both 100% and 10% outgassing rates. This result is in agreement with the observed spectra and leads to tighter mass constraints for Sedna. Our model also explains the observed absence of methane on another KBO, Gonggong.

title: Overview of the Deep Space Optical ommunications (DSOC) technology demonstration

description: The National Aeronautics and Space Administration (NASA) Deep Space Optical Communications (DSOC) Project implemented by the Jet Propulsion Laboratory (JPL), has completed weekly optical link demonstrations from November 2023 – December 2024, following the Psyche spacecraft launch in October 2023. The flight laser transceiver, hosted by NASA’s Psyche spacecraft, along with optical ground stations located in Southern California were used. Over this period, downlink data-rates of 6.25 – 267 Mb/s were achieved over deep space distances of 0.2 – 2.7 astronomical units (AU), or 30 – 400 million Km. Optical link acquisition, tracking and pointing was initiated with a modulated uplink laser assembly that also delivered communications at a fixed rate of 1.8 kb/s over distances of 0.2 – 3.3 AU.
