We propose to use the unique high-resolution optical and ultraviolet capabilities of HST as well as the resolution and sensitivity of Chandra to investigate the physics of gamma-ray bursts {GRBs} and the nature of their host galaxies. Our approach is three-pronged: 1} rapid HST ultraviolet spectroscopy and Chandra imaging obtained within two days of an outburst will allow us to probe the physics of the relativistic fireball and the nature of the ISM surrounding the GRB; 2} long-term optical monitoring of the optical transient {OT} will permit us to test the hypothesis that GRBs are frequently highly collimated and to determine whether supernovae underlie GRBs; 3} Chandra and HST observations of "dark" GRBs will allow us to probe one of the greater mysteries surrounding GRBs, the nature of the bursts without optical counterparts. The ultraviolet and x-ray observations will also obtain the metal and rmH_2 column densities to a number of OTs, as well as the extinction law of the dust in these hosts. The late-time optical images will elucidate the physics of the afterglow, as well as the morphology, structure and luminosity function of the host galaxies. This comprehensive set of observations will provide new insights into the astrophysics of GRBs and their high redshift host galaxies.
