Europa Clipper Mission Analysis: Design of the 21F31 Reference Trajectory
Apr 22, 2024
Stefano Campagnola, 2024, "Europa Clipper Mission Analysis: Design of the 21F31 Reference Trajectory", https://doi.org/10.48577/jpl.LBUCWP, 29th International Symposium on Space Flight Dynamics (ISSFD), JPL Open Repository
Europa has been a prime target for space exploration ever since 1997, when the Galileo spacecraft magnetic measurements of Europa suggested the moon might hide a vast, salty ocean beneath its icy surface. To investigate its habitability, NASA developed Europa Clipper, which will...
The NASA/ESA Mars Sample Return Campaign
Apr 22, 2024
Tomas Martin-Mur, 2024, "The NASA/ESA Mars Sample Return Campaign", https://doi.org/10.48577/jpl.LYSMHS, 29th International Symposium on Space Flight Dynamics (ISSFD), JPL Open Repository
This paper outlines the proposed architecture of the Mars Sample Return (MSR) campaign planned in collaboration by the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA). The goal of the campaign is to bring to Earth a scientifically selected...
Target Detection and Orbit Determination for Mars Sample Return
Apr 22, 2024
Zubin Olikara, 2024, "Target Detection and Orbit Determination for Mars Sample Return", https://doi.org/10.48577/jpl.ZMG433, 29th International Symposium on Space Flight Dynamics (ISSFD), JPL Open Repository
The Mars Sample Return campaign is a joint effort being planned by the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) to bring back a curated set of samples from the Jezero crater region of Mars to Earth. A fundamental part of this campai...
Mars Sample Return Direct Earth Approach Navigation Analysis
Apr 22, 2024
Gerhard Kruizinga, 2024, "Mars Sample Return Direct Earth Approach Navigation Analysis", https://doi.org/10.48577/jpl.BSEKXJ, 29th International Symposium on Space Flight Dynamics (ISSFD), JPL Open Repository
This paper describes the navigation analysis, results and filter strategies planned by the European Space Agency (ESA) and the National Aeronautical and Space Administration (NASA) navigation Teams for the joint ESA and NASA Mars Sample Return (MSR) mission, targeting a direct ap...
Photon-Counting for deep space optical copmmunications
Apr 21, 2024
Abhijit Biswas, 2024, "Photon-Counting for deep space optical copmmunications", https://doi.org/10.48577/jpl.7CTCMG, SPIE Defense + Commercial Sensing 2024, JPL Open Repository
Motivated by the need for higher data volume return from NASA’s future planetary missions, the deep space optical communications (DSOC) technology demonstration (TD) was initiated. The DSOC project integrated a flight laser transceiver to the Psyche Mission spacecraft which launc...
Intelligent Knowledge Base Search Tool using Large Language Model and Graph Neural Network
Apr 21, 2024
Thomas Lu, 2024, "Intelligent Knowledge Base Search Tool using Large Language Model and Graph Neural Network", https://doi.org/10.48577/jpl.UEKXQI, SPIE Defense + Commercial Sensing 2024, JPL Open Repository
ABSTRACT Within many organizations, a vast number of communications, memos, reports and documents have been accumulated in internal servers. Efficiently discovering relevant entries can reduce time spent addressing organizational needs such as personnel skills matching or anomaly...
The Best of Both Worlds: Combining Parametric Cost Risk Analysis with Earned Value Management Using Bayesian Parameter Learning
Apr 16, 2024
Christian Smart, 2024, "The Best of Both Worlds: Combining Parametric Cost Risk Analysis with Earned Value Management Using Bayesian Parameter Learning", https://doi.org/10.48577/jpl.LRTTEZ, Defense and Aerospace Test and Analysis Workshop, JPL Open Repository
Cost risk analysis and earned value data are typically used separately and independently to compute Estimates at Completion (EAC). However, combining the two can significantly improve the accuracy of EAC forecasting. This paper provides a rigorous method using Bayesian methods. W...
Evaluating The Capability of the SPARTA Toolkit to Quantitatively Characterize Planetary Regolith
Apr 15, 2024
Robert Anderson, 2024, "Evaluating The Capability of the SPARTA Toolkit to Quantitatively Characterize Planetary Regolith", https://doi.org/10.48577/jpl.PTUFUS, Earth & Space 2024, JPL Open Repository
The overall success of NASA’s strategic objective of placing humans on extraterrestrial planetary surfaces depends on a thorough understanding of a planetary regolith's near-surface environmental and geomechanical properties. Comprehensive in situ characterization of planetary re...
Acoustics and RF communication thru deep ice for application to ocean worlds exploration
Mar 25, 2024
Yoseph Bar-Cohen, 2024, "Acoustics and RF communication thru deep ice for application to ocean worlds exploration", https://doi.org/10.48577/jpl.MXSIR5, SPIE Smart Structures and Nondestructive Evaluation 2024, JPL Open Repository
One of NASA’s priorities is the in-situ exploration of ocean worlds in the solar system where there may potentially exist life under the ice shell. This requires reaching the ocean below through great depths of ice at extremely low temperatures. Jupiter’s moon Europa is such a ch...
Piezoelectric motor for cryogenic applications
Mar 25, 2024
Yoseph Bar-Cohen, 2024, "Piezoelectric motor for cryogenic applications", https://doi.org/10.48577/jpl.D4KMUF, SPIE Smart Structures and Nondestructive Evaluation 2024, JPL Open Repository
Expanding the capabilities that are used in the NASA’s exploration of planetary bodies in our solar system would require mechanisms and actuators that can operate at cryogenic temperatures (-240 °C to -60 °C) in dusty environments. These applications include the exploration of lu...
