In all these duties the ST-ECF staff maintained close contacts with the Space Telescope Science Institute (STScI) in Baltimore, which is charged with the scientific operation of the HST observatory.
When internet connections across the Atlantic and powerful computers became the mainstay, the focus of the organization shifted towards data product and dedicated instrument science support.
The ST-ECF was actively engaged in software development in many areas related to HST data calibration, analysis and visualisation for especially the Hubble instruments Faint Object Spectrograph, STIS, and Advanced Camera for Surveys.
For example: Together with the European Southern Observatory (ESO) the ST-ECF operated and maintained the ESO/ST-ECF Science Archive Facility from where all the scientific data collected by the Hubble Space Telescope could be accessed by the public.
Furthermore the group produces video releases, innovative educational material, CD-ROMs, brochures, posters, as well as DVDs and museum information kiosks, and much more.
