Nicholas Parazoo, 2024, "More Frequent Spaceborne Sampling of XCO2 Improves Detectability of Carbon Cycle Seasonal Transitions in Arctic-Boreal Ecosystems", https://doi.org/10.48577/jpl.ALTZNF, Geophysical Research Letters, JPL Open Repository
Surface, aircraft, and satellite measurements indicate pervasive cold season CO2 emissions across Arctic regions, consistent with a hyperactive biosphere and increased metabolism in plants and soils. A key remaining question is whether cold season sources will become large enough... |

Oscar Fuentes Munoz, 2024, "Asteroid Orbit Determination using Gaia FPR: Statistical Analysis", https://doi.org/10.48577/jpl.LXBLGU, Astronomical Journal, JPL Open Repository
The Gaia mission has provided astrometric observations of unprecedented accuracy for more than7 156000 asteroids. The reported astrometric uncertainties are of the order of milliarcseconds, about8 two orders of magnitude smaller than that of traditional ground-based observations.... |

Ethan Elliott, 2024, "Deployment of a Binary Atomic Species Superfluid in Space", https://doi.org/10.48577/jpl.NXBPPC, Nature, JPL Open Repository
The legacy of experimentally testing the universality of free fall (UFF), held by Einstein to be at the core of his gravitational theory, reaches back to the Renaissance and continues today. In modern theories, the foundations of gravity may yet yield to those of quantum mechanic... |

Rosaly Lopes, 2024, "The temporal variability 1 of Io’s hotspots", https://doi.org/10.48577/jpl.X9TPCW, Frontiers in Astronomy, JPL Open Repository
We investigate the variability of the power emission of Io’s hotspot by using recent Juno/JIRAM infrared observations. The Jovian Infrared Auroral Mapper (JIRAM) is an imaging spectrometer which began observing Jupiter in August 2016. Although observing Jupiter’s moons is not its... |

James Wallace, 2024, "Analyzing the Atmospheric Dispersion Correction of the Gemini Planet Imager: residual dispersion above design requirements", https://doi.org/10.48577/jpl.DD1WRF, Journal of Astronomical Telescope, Instrumentation, and Systems, JPL Open Repository
The Atmospheric Dispersion Corrector (ADC) of the Gemini Planet Imager (GPI) corrects the chromatic dispersion caused by differential atmospheric refraction (DAR), making it an important optic for exoplanet observation. Despite requiring less than 5 mas of residual DAR to avoid p... |

Anatoliy Savchenkov, 2024, "Low Noise W-band Photonic Oscillator", https://doi.org/10.48577/jpl.LSTJ8Z, J. SEL. TOP. QUANTUM ELECTRON., JPL Open Repository
Photonic oscillators are capable of generating spectrally pure radio, microwave and millimeter wave signals by optical means. The oscillators take advantage of a long lifetime optical energy storage element, such as optical delay line or a cavity, to produce the signals. We here... |

Richard Zurek, 2024, "MRO Overview: Sixteen Years in Mars Orbit", https://doi.org/10.48577/jpl.9EPUWM, Icarus, JPL Open Repository
The Mars Reconnaissance Orbiter (MRO) entered Mars orbit on March 10, 2006, and as of September 2023 has been in its primary science orbit for 17 years. By the end of its current extended mission in September 2025, MRO observations will have covered a Mars decade (~19 Earth years... |
