Hubble Space Telescope Science Metrics

Since its launch in 1990 April, the Hubble Space Telescope(HST) has produced an increasing flow of scientific results. The large number of refereed publications based on HST data permits a detailed evaluation of the effectiveness of this observatory and its scientific programs. This paper presents the results of selected science metrics related to paper counts, citation counts, citation history, high-impact papers, and the most productive programs and most cited papers through the end of 2003. All these indicators point toward the high- quality scientific impact of HST.
