The present approach to that task is organized around two major areas of mission performance, orbit plane precession and coverage pattern development, whose dependence on altitude and inclination is delineated graphically in design chart form. A number of important mission performance characteristics depend on these choices, however, so a major part of the orbit selection task is concerned with developing the correlating relationships in clear and convenient forms to provide a basis for rational orbit selection procedures. The orbit selection process is simplified for most earth-oriented satellite missions by a restriction to circular orbits, which reduces the primary orbit characteristics to be determined to only two: altitude and inclination. Orbit Selection for Earth Observation Missions Cloud cover is indicated with an image layer from the MODIS (Moderate Resolution Imaging Spectroradiometer) aboard the Aqua satellite, which is automatically retrieved from JPL s On Earth Web service. Zoom, pan, and rotate capability are provided through the standard Google Earth interface. In addition, ancillary data, such as the column-averaged dry air mole fraction of carbon dioxide and solar zenith angle, are automatically extracted from a Level 2 mission data product. The application automatically extracts the spacecraft position and ground footprint geometry as a function of time from a daily Level 1B data product created and archived by the mission s ground data system software.

Alternatively, the daily KML for a specified mission day may be generated. Each time the application runs, the daily orbit paths are encapsulated in a KML file for each mission day since the last time the application ran. These KML data products can be directly loaded into the Google Earth application for interactive 3D visualization of the orbit paths for each mission day.

This software can be integrated with the ground data system for any Earth-observing mission to automatically generate daily orbit path data products in Google Earth KML format. In addition, a drill-down capability allows for users to point and click on a particular observation frame to pop up ancillary information such as data product filenames and directory paths, latitude, longitude, time stamp, column-average dry air mole fraction of carbon dioxide, and solar zenith angle. The software uses the Google Earth user interface to provide a visual mechanism to explore spacecraft orbit paths, ground footprint locations, and local cloud cover conditions. This software visualizes orbit paths for the Orbiting Carbon Observatory (OCO), but was designed to be general and applicable to any Earth-observing mission. This paper describes the processes that resulted in successful orbit raise designs for both spacecraft.ДЈD Orbit Visualization for Earth-Observing Missions The Artemis mission required transferring two Earth orbiting Themis spacecraft on to two different low energy trans-lunar trajectories ultimately ending in lunar orbit. The goal of the Artemis2 mission extension is to deliver the field and particle measuring capabilities of two of the Themis spacecraft to the vicinity of the Moon.

The Themis spacecraft are spin stabilized with 20 meter long electric field booms as well as several shorter magnetometer booms. Themis was meant to answer the age old question of why the Earth's aurora can change rapidly on a global scale. Themis was designed to observe geomagnetic storms resulting from solar wind's interaction with the Earth's magnetosphere.

The Themis mission1 consisted of five identical spacecraft in varying sized Earth orbits designed to make simultaneous measurements of the Earth's electric and magnetic environment. The Artemis mission is an extension of the Themis mission.
