Marzia Parisi, 2021, "Gravity investigation of Saturn's inner system with the innovative Ring Skimmer concept", https://doi.org/10.48577/jpl.SFBVTZ, The Planetary Science Journal, JPL Open Repository
We present an in-depth feasibility study of innovative gravity science measurements of Saturn’s inner system, which explores the different regions of the rings, the innermost moons and the planet itself. The study is enabled by the novel Skimmer concept, where the spacecraft graz... |

Davis, Anthony B, 2021, "GEOSCAN: Global Earth Observation using Swarm of Coordinated Autonomous Nanosats", https://doi.org/10.48577/jpl.WJSBNH, Preprint Server, JPL Open Repository
The climate crisis we are facing calls for significant improvements in our understanding of natural phenomena, with clouds being identified as a dominant source of uncertainty. To this end, the emerging field of 3D computed cloud tomography (CCT) aims to more precisely characteri... |

Scott, David C, 2021, "Voyager 3: A Concept Mission to Interstellar Medium", https://doi.org/10.48577/jpl.QLGF8V, AIAA Journal of Spacecraft and Rockets, JPL Open Repository
The Voyager 3 is a concept mission that sends a space telescope to the interstellar medium in a reasonable amount of time. Voyager 3 will take a direct image of an exoplanet using the solar gravitational lensing at the distance of 550 AU. The spacecraft will use its suite of scie... |

Keeyoon Sung, 2021, "Improved line list of 12CH4 in the 4100-4300 cm-1 region", https://doi.org/10.48577/jpl.EG0DRO, Journal of Quantitative Spectroscopy and Radiative Transfer, JPL Open Repository
Four spectra of methane in natural isotopic abundance in the 4100-4300 cm-1 region were recorded by using a Fourier transform spectrometer in Reims, France at long paths (202 m, 602 m, 1604 m and 1804 m) and different pressures. Additional spectra of 12CH4 covering the same regio... |

Patthoff, D. Alex A, 2021, "Thrust Faulting as the Origin of the Dorsa on the trailing hemisphere of Enceladus", https://doi.org/10.48577/jpl.PUBCJD, Icarus, JPL Open Repository
Several large ridges, termed dorsa, stand over 800 m above their surroundings in a region centered on the trailing hemisphere of Saturn’s icy moon Enceladus. In map view, these dorsa are linear to curvilinear, 20 km to more than 50 km long, and display nearorthogonal trends. They... |

Slava Turyshev, 2021, "Navigating stellar wobbles for imaging with the solar gravitational lens", https://doi.org/10.48577/jpl.TFJEUU, Physical Review D, JPL Open Repository
The solar gravitational lens (SGL) offers unique capabilities for direct high-resolution imaging of faint, distant objects, such as exoplanets. For that purpose, in the near future, a spacecraft carrying a meter-class telescope with a solar coronagraph would be placed in the foca... |

Neal Turner, 2021, "Accreting protoplanets: Spectral signatures and magnitude of gas and dust extinction at Hα", https://doi.org/10.48577/jpl.NXJTZK, Astronomy & Astrophysics, JPL Open Repository
Context. Accreting planetary-mass objects have been detected at Hα, but targeted searches have mainly resulted in non-detections. Accretion tracers in the planetary-mass regime should originate from the postshock region, making them particularly susceptible to extinction by the a... |

Baskaran, Latha, 2021, "Geomorphological Patterns of Remotely Sensed Methane Hot Spots in the Mackenzie Delta, Canada", https://doi.org/10.48577/jpl.GXDYP9, Environmental Research Letters, JPL Open Repository
We studied geomorphological controls on methane (CH4) hotspots in the Mackenzie Delta region in northern Canada using airborne imaging spectroscopy collected as part of the Arctic Boreal Vulnerability Experiment (ABoVE). Methane emissions hotspots were retrieved at ~25 m2 spatial... |

Mages, Declan M, 2021, "Navigating Fast Interstellar Object Encounters", https://doi.org/10.48577/jpl.HEJIUP, Acta Astronautica, JPL Open Repository
With the discovery of 1I 'Oumuamua and 2I Borisov, interstellar objects (ISOs) have been thrust into the forefront of planetary science, and the robotic exploration of ISOs is now of significant interest. With current propulsion technology, rendezvous with these objects is likely... |
