The UV Initiative, in place since Cycle 21, recognizes the unique capability that Hubble has in accessing the ultraviolet (UV) portion of the electromagnetic spectrum (wavelengths less than 3200 Angstroms). Nearly all categories of proposals (Small, Medium, Large, and Treasury GO proposals, as well as Regular Archival, Legacy Archival, and Theory proposals) are eligible for the UV Initiative. The science programs being conducted under the UV Initiative span almost all science categories.

Below are two tables listing the two types of programs: General Observer programs and Archival 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. Click on column heading to sort.
