The STScI Director has commissioned reports from a number of working groups on community initiatives covering topics such Deep Fields, the ULLYSES project, HST observations of gravitational wave optical counterparts, and the HST-TESS initiative.

Those reports can be found on STScI's Outerspace, a service for collaboration and engagement with the astronomical community and our partners.
