Supernovae explode to create the chemical history of the Universe and energize the interstellar gas. They now occupy center stage for the extragalactic distance scale and cosmology. The SINS program has shown how HST can make unique contributions to understanding supernovae. HST is better than ever for this work: STIS is ideal for spatially-resolved observations of SN 1987A, where a rapidly developing encounter between the fast-moving debris and the stationary inner ring is underway. Observations of UV emission inside the inner ring of SN 1987A reveal the location and velocity of the reverse shock that also produces X-ray and radio emission. We also plan intensive study of illuminating objects beyond SN 1987A: a Target-of-Opportunity observation of a bright, new supernova that is certain to be discovered during Cycle 9, and the late-time observations of SN 1999by {SN Ia} and SN 1998bw, {SN Ic? and probably Gamma-ray burst}. We request a 24-hour turn-around because the UV flux from supernovae changes rapidly in the first days and reveals much about the star. We will explore the UV emission from supernovae, exploit the spatial resolution of HST, and press the late-time observations of supernovae into uncharted territory. The SINS team enriches HST data with extensive ground-based support and analytic power to help understand the final and most violent stage of stellar evolution.
