Huggins, Grayson; Talaksi, Ali; Lightsey, E. Glenn; Andrews, Dawn; Cavender, Daniel; Diaz, Carlos; McQueen, Donald; Williams, Hunter; Baker, John; Kowalkowski, Matthew, 2021, "Development of a CubeSat-Scale Green Monopropellant Propulsion System for NASA's Lunar Flashlight Mission", https://hdl.handle.net/2014/53314, AIAA SciTech 2021, Nashville, Tennessee, January 11-21, 2021, JPL Open Repository
NASA's Lunar Flashlight is a low-cost 6U CubeSat whose mission is to search for ice and mineral deposits inside of the scattered craters at Moon's southern pole. To conduct its primary science mission, Lunar Flashlight must be placed in a stable lunar polar orbit which requires t... |

David; Freebury, Gregg; Medina, Kamron; Hepper, David; Turse, Dana; Antoun, George; Rupp, Cory; Hoffman, Laura, 2021, "Origami-Inspired Optical Shield for a Starshade Inner Disk Testbed: Design, Fabrication, and Analysis", https://hdl.handle.net/2014/53302, AIAA SciTech 2021, Nashville, Tennessee, January 11-21, 2021, JPL Open Repository
In 2019, a 10 m-diameter starshade inner disk test article was assembled; this test article demonstrated deployment accuracy sufficient for starshade mission concepts. Here, we describe the design, fabrication, and computational structural analysis of a key inner disk component r... |

Stuart Shaklan, 2021, "Exep: A realistic Determination of Observational Completeness Usingthe Starshade", https://doi.org/10.48577/jpl.GTYNU2, Caltech Undergraduate Research Journal, JPL Open Repository
The Starshade is a rising tool to be used in exoplanetary imaging to look for Earth-like planets. Positioned between the telescope and the star, the Starshade blocks the starlight from the telescope’s mirrors. Previous studies have estimated the Earth-like exoplanet yields of fut... |

Neal Turner, 2021, "The Interplanetary and Magnetospheric Causes of Geomagnetically Induced Currents (GICs) > 10 A in the Mäntsälä Finland Pipeline: 1999 through 2019", https://doi.org/10.48577/jpl.1YGXKP, The Journal of Space Weather and Space Climate, JPL Open Repository
The interplanetary and magnetospheric causes of intense geomagnetically induced current (GIC) > 10 A (and > 30 A) events during 21 years (1999 through 2019) at the Mäntsälä, Finland (57.9° magnetic latitude) gas pipeline have been studied. Although shocks and substorms are pre... |

Aumann, Hartmut H, 2021, "Evaluation of AIRS and CrIS SST measurements relative to three globally gridded SST products between 2013 and 2019.", https://doi.org/10.48577/jpl.4OMGMK, IEEE Trans. Geosci. Remote Sens., JPL Open Repository
Globally gridded sea surface temperatures (SST) are useful for providing boundary conditions for atmospheric models and for the long-term monitoring of satellite derived SSTs. The Real Time Global (RTG) SST from NOAA has been used for the past decade to evaluate the stability and... |

Jonathan Jiang, 2021, "A Statistical Estimation of the Occurrence of Extraterrestrial Intelligence in the Milky Way Galaxy", https://doi.org/10.48577/jpl.QQPN7W, Galaxies, JPL Open Repository
In the field of Astrobiology, the precise location, prevalence and age of potential extraterrestrial intelligence (ETI) have not been explicitly explored. Here, we address these inquiries using an empirical galactic simulation model to analyze the spatial-temporal variations and... |
