Aaron Kiely, 2022, "CCSDS 123.0-B-2 Compression Standard Cross-Validation and Fuzzing", https://doi.org/10.48577/jpl.UMSSRS, 8th International On-Board Payload Data Compression (OBPDC), JPL Open Repository
The Consultative Committee for Space Data Systems requires candidate standards to complete a ‘cross-validation’ process in which two or more independent implementations of the candidate standard are shown to produce equivalent results. Four different groups each created an indepe... |

Didier Keymeulen, 2022, "Hyperspectral Data Compression and Cloud Screening using a High-Performance Embedded System-on-a-Chip for the Earth Surface Mineral Dust Source (EMIT) Instrument on the International Space Station (ISS)", https://doi.org/10.48577/jpl.4SHWQJ, 8th International Workshop on On-Board Payload Data Compression (OBPDC 2022), JPL Open Repository
System-on-a-chip (SoC) devices promise lighter, smaller, cheaper, more capable and more reliable space electronic systems. This paper describes the focal plane interface electronics – digital (FPIE-D) Xilinx Zynq-based data acquisition, cloud-screening, compression, storage and d... |

Matthew Thill, 2022, "Machine-Learned Data Compression for Outer Solar System Missions", https://doi.org/10.48577/jpl.ovngmyrh, 8th INTERNATIONAL WORKSHOP ON ON-BOARD PAYLOAD DATA COMPRESSION (OBPDC 2022), JPL Open Repository
It is easy to take for granted our ability to draw scientific information from distant interplanetary spacecraft, particularly those in outer solar system missions. The Cassini Imaging Science Subsystem (ISS), for example. has returned a wealth of high-resolution images of Saturn... |

Michelle Drabik, 2022, "From Information to Knowledge and Back Again: How NASA Libraries and Knowledge Management Work Together for the Advancement of Space Science", https://doi.org/10.48577/jpl.5H9YOJ, IAC International Astronautical Congress 2022, JPL Open Repository
This paper outlines the history of and continuing association between NASA libraries and knowledge offices, with a special focus on this relationship at NASA’s Jet Propulsion Laboratory, and will be informed by interactions within other space agencies and private industry. Librar... |

Caroline Coward, 2022, "A Traveling Hub of Information: An organizational history of the Library at NASA Jet Propulsion Laboratory", https://doi.org/10.48577/jpl.DNDZUB, IAC International Astronautical Congress 2022, JPL Open Repository
The Library at NASA’s Jet Propulsion Laboratory has undergone many changes to staffing, functions, services, and physical space in its seven decades of continuous operation, but none more curious and interesting than its assignments to various reporting organizations over time. T... |

Dan Goods, 2022, "Altamira Comet Proof-of-Concept", https://doi.org/10.48577/jpl.TEGCHC, IAC International Astronautical Congress 2022, JPL Open Repository
Beginning some 30,000 years ago, nine of our Paleolithic ancestors painted their unique hands on the walls of Altamira Cave in Cantabria, Spain—an act of communication by the community, for the community. We present a proof-of- concept for the Altamira Comet, a 21st century work... |

David Atkinson, 2022, "Setting the Record Straight: The Galileo Probe Mission Was a Success!", https://doi.org/10.48577/jpl.Z2FAAS, IAC International Astronautical Congress 2022, JPL Open Repository
Misperceptions regarding the operational success and science accomplishments of the Galileo Jupiter atmospheric entry probe have acquired an inertia that threatens the perceived value, risk, and consideration of future giant planet entry probe missions. These misperceptions large... |

Rodney Anderson, 2022, "Transfers between Jupiter-Ganymede and Jupiter-Europa Resonant Tori In a Concentric Circular Restricted 4-Body Model", https://doi.org/10.48577/jpl.DRMXCP, IAC International Astronautical Congress 2022, JPL Open Repository
The phenomenon of mean-motion resonance overlapping, which generates heteroclinic connections between unstable resonant orbits, is known to be crucial for the generation of large-scale chaos and global instability in celestial systems. This instability in turn can be profitably l... |

Sean Pham, 2022, "Shock Model and Test Correlation for Structural Response Prediction", https://doi.org/10.48577/jpl.SN0PPC, SAVE: 92nd Shock and Vibration Symposium, JPL Open Repository
When defining hardware shock environments, it is typical to assume a reduction of shock levels through structural joints – nominally, a 30% reduction per joint up to a maximum of three joints. However, review of shock test data from a flight-like test article demonstrates that at... |
