HST Treasury, Archival Legacy and Large Programs

Several special types of programs were created for the Hubble Space Telescope beginning in Cycle 11. Chief among these are the Treasury, Archival Legacy and Large programs. The goal of these programs is to increase the scientific impact of HST, in part by providing sets of high-level science products to the astronomical community that are useful for addressing multiple scientific topics. MAST also encourages the contribution of high-level science products from all HST programs and from other MAST based missions.

Please consult the guidelines for contributing high-level science products for more information. You may see a complete list of all high-level science products archived at MAST and also search for a variety of criteria to find HLSP of interest. You may also be interested in more information about download options.

Below are three tables listing the three types of programs. The planned orbit counts may not be completely accurate especially for multi-cycle programs. These tables are compiled on the fly and may take a few seconds to load.
