JWST Preparatory Programs

The James Webb Space Telescope (JWST) is NASA's flagship mission scheduled to launch in October 2018, that will offer extensive photometric and spectroscopic capabilities in the 0.7-28 micron wavelength region. In some cases, Hubble observations are essential to achieving critical science goals for future JWST programs.The JWST Initiative, starting with HST Cycle 24, is designed to provide an opportunity to obtain observations with Hubble that complement and enhance the scientific impact of JWST observations. The following accepted proposals indicated that they were preparatory programs for accomplishing breakthrough science with JWST.

The links below give bibliographical information related to each accepted program. The planned orbit counts may not be completely accurate especially for multi-cycle programs.
