JWST Moving Target Roadmap

A roadmap to guide users, step-by-step, through the process of creating moving target (Solar System) observations with JWST is provided in this article.

  1. Familiarize yourself with policies related to moving targets.

    Moving Target Overheads

  2. Familiarize yourself with apparent motion and pointing constraints for moving target observations with JWST.

  3. Generate an ephemeris using the JPL/Horizons system to determine the best time to observe the target.

  4. Determine the instrument and observing mode for your moving target observation.

  5. Calculate the required exposure time and detector readout parameters using the Exposure Time Calculator (ETC).
