To better guarantee the reliability of cosmological calibrations based upon UV spectroscopy of objects in the SMC, we propose to use HST's Fine Guidance Sensor {FGS 1R} to conduct high angular resolution observations of some of the SMC's hottest and most luminous objects. Our plan calls for a comprehensive survey of nearly every spectral type in the upper portion of the HR diagram. Binary or multiple star systems will be detected down to an unprecedented 0.arcs007 {460 A.U.}, more than one order of magnitude better than possible with WFPC2. The targets we've selected include a representative list of normal Main Sequence O-stars and their evolved descendents, namely supergiants, hypergiants, LBVs, and WRs, many of which have been observed by HST's spectrometers for purposes of cosmological calibrations. The data from these observations will place much tighter limits on the binary status of these objects and fundamentally enhance our knowledge of the SMC's upper IMF and upper stellar mass limit.
