The LUVOIR Mission Concept: Update and Technology Overview This paper provides an overview of the science, mission and spacecraft design resulting from that study. That uses aerocapture as the Neptune orbit insertion mechanism. The primary objectives were to assess the feasibility of a spacecraft point design for a Neptune/Triton science mission. O'Kongo, NoraĪ detailed Neptune aerocapture systems analysis and spacecraft design study was performed as part of NASA's In-Space Propulsion Program.

the Jupiter Icy Moons Orbiter (JIMO) mission uses ion thrusters powered by a nuclear reactor to transfer from Earth to Jupiter and enter a low-altitude science orbit around each of the moons. Jupiter icy moons orbiteer mission design overviewĪn overview of the design of a mission to three large moons of Jupiter is presented. The method is demonstrated on the example of the JMAPS mission, but can be used for other projects in space astrometry, such as SIM or JASMINE.Ĭorrelated and Zonal Errors of Global Astrometric Missions: A Spherical Harmonic Solution

Both accidental and systematic correlated errors of astrometric parameters can be accurately estimated. In our method, the simulated observational equations are set up and solved for the coefficients of scalar and vector spherical harmonics representing the output errors rather than for individual objects in the output catalog. We propose a computer-efficient and accurate method of estimating spatially correlated errors in astrometric positions, parallaxes, and proper motions obtained by space- and ground-based astrometry missions. We propose an information representation called Timeline as an approach to enable such a move, and we provide an overview of a Timeline-based Mission Operations System architecture.ĬORRELATED AND ZONAL ERRORS OF GLOBAL ASTROMETRIC MISSIONS: A SPHERICAL HARMONIC SOLUTION

In this paper, we provide an overview of these challenges and argue the need to move toward an information-centric mission operations system. An important contributing factor to both of these challenges is the file-centric nature of today's systems.

Some of the challenges in developing a mission operations system and operating a mission can be traced back to the challenge of integrating a mission operations system from its many components and to the challenge of maintaining consistent and accountable information throughout the operations processes. Timeline-Based Mission Operations Architecture: An Overview The J-MAPS baseline also includes a novel filter-grating wheel, of interest in the area of non- resolved object characterization. By optimizing an instrument to perform position measurement rather nsors. One implication of this is that the instrument can physically resolve satellites at smaller separations than current and existing optical SSA assets.with the potential for 24/7 taskability and near-real time capability.
