Chui, Talso C, 2022, "Extensions of the Galperin Transformation Matrices for Triaxial Seismometers", https://doi.org/10.48577/jpl.L8FPI0, Sensors, JPL Open Repository
Modern triaxial seismometers often employ a symmetric configuration that includes three identical sensors, each with a proof mass suspended on a boom pointing at the same “Galperin” tilt angle (tan^(-1)〖1/√2〗 or 35.26°) with respect to vertical. A well-known transformation matri... |

Orton, Glenn S, 2022, "Alternating North-South Brightness Ratio of Ganymede's Auroral Ovals: Hubble Space Telescope Observations Around the Juno PJ34 Flyby", https://doi.org/10.48577/jpl.T89BUG, Geophysical Research Letters, JPL Open Repository
We report results of Hubble Space Telescope observations from Ganymede’s orbitally trailing side which were taken around the flyby of the Juno spacecraft on June 7, 2021. We find that Ganymede’s northern and southern auroral ovals alternate in brightness such that the oval facing... |

Nitin Singh, 2022, "Machine learning algorithm to characterize antimicrobial resistance associated with the International Space Station surface microbiome", https://doi.org/10.48577/jpl.GJ5FL2, microbiome, JPL Open Repository
Background: Antimicrobial Resistance (AMR) has a detrimental impact on humanhealth on Earth and it is equally concerning in other environments such as space dueto microgravity, radiation and confinement, especially for long-distance space travel.The International Space Station (I... |

Nikolic, Dragan, 2022, "Method for accurate detection of amino acids and mycotoxins in planetary atmospheres", https://doi.org/10.48577/jpl.SNYYGM, Life, JPL Open Repository
We present a systematic analysis of a large number of mass spectra accumulated as the number of ion fragments recorded in unit mass-to-charge detector channels. The method retrieves the abundances of detected species using an efficient deconvolution algorithm, which relies on fra... |

Nitin Singh, 2022, "Multidrug-resistant Acinetobacter pittii is adapting to and exhibited succession on aboard the International Space Station", https://doi.org/10.48577/jpl.XC5M6S, Microbiome, JPL Open Repository
Monitoring adaptation of microorganisms to the extreme environment of the International Space Station (ISS) is crucial to understanding microbial evolution and determining how to protect astronauts from potential infections. Acinetobacter pittii is an opportunistic nosocomial pat... |

Estrela, Raissa F, 2022, "Clouds and Hazes in Exoplanet Atmospheres: A Comparative Planetology Study Using Uniformly Processed HST/WFC3 data", https://doi.org/10.48577/jpl.TRZGGP, The Astrophysical Journal Letters, JPL Open Repository
The transmission spectra of exoplanet atmospheres observed with the Hubble Space Telescope (HST) in the near-infrared range (1.1-1.65µm) frequently show evidence for some combination of clouds and hazes. Identification of systematic trends in exoplanet clouds and hazes is potenti... |

David, Cedric H, 2022, "Groundwater Depletion in California’s Central Valley Accelerates During Megadrought", https://doi.org/10.48577/jpl.YKGUYH, Nature Communications, JPL Open Repository
Groundwater provides nearly half of irrigation water supply, and it enables resilience during drought, but in many regions of the world, it remains poorly, if at all managed. In heavily agricultural regions like California’s Central Valley, where groundwater management is being s... |

Vance, Steve D, 2022, "Surface-to-ocean exchange by the sinking of impact generated melt chambers on icy ocean worlds", https://doi.org/10.48577/jpl.JIRMBM, Geophysical Research Letters, JPL Open Repository
Impacts into icy bodies often generate near-surface melt chambers and thermal perturbations that soften the ice. We explore the post-impact evolution of nonpenetrating impacts into Europa’s ice shell. Numerical 5 simulations of viscous ice deformation show that dense impact melts... |

Turner, Neal J, 2022, "Hyperion: The origin of the stars -- A far-UV space telescope for high-resolution spectroscopy over wide fields", https://doi.org/10.48577/jpl.B1LMH7, Journal of Astronomical Telescope, Instrumentation, and Systems, JPL Open Repository
We present Hyperion, a mission concept recently proposed to the December 2021 NASA Medium Explorer announcement of opportunity. Hyperion explores the formation and destruction of molecular clouds and planet-forming disks in nearby star-forming regions of the Milky Way. It does th... |
