The Hubble Space Telescope Key Projecton the Extragalactic Distance Scale
"The distance scale path has been a long and tortuous one,but with the imminent launch of HST there seems good reason to believethat the end is finally in sight."

The Key Project
The main goal of the HST Key Project on the ExtragalacticDistance Scale is to determine the Hubble Constant, H0, toan accuracy of +/- 10%. This goal will be achieved by thesystematic observations of Cepheid variable stars severalgalaxies using the Hubble Space Telescope. The Key Project teamcurrently has 28members.Alist of Key Project papers that have been published, in press, submitted, or in preparation is available. of the Extragalactic Distance Scale Key Project.Archival material appears after the paper has been accepted forpublication.
