Key issues pertaining to the study of supernovae are listed, and the characteristics of instruments for addressing the issues are discussed with reference given to the present status of supernova investigation. Understanding type-Ia supernovae requires study of the progenitor star, the isotopic composition of the ejecta, and the radiation transport. Issues relevant to type Ib's include identifying clumping and fragmentation in the model light curves and determining whether mixing occurs. Identifying progenitor stars and observing neutrino bursts are found to be keys to understanding the supernovae, and appropriate analyses include optical imaging, bolometry, spectroscopy, and most importantly, high-resolution IR imaging. Gamma- and X-ray studies are also important, and examples of suitable telescopes are listed; investigation of neutrinos requires an observatory away from terrestrial nuclear reactors.
