Details: Our current cosmological model is compelling and simple, but puzzling in that two-thirds of the universe seems to be composed of a new form of energy, termed dark energy, which reveals itself only through the accelerated expansion it causes. Although several promising methods exist for exploring dark energy, the best probe is likely to be through observation of Type Ia supernovae. This talk will examine two methods for measuring the light from these objects with space-borne telescopes and a comparison of their relative strengths and weaknesses. Due to the fundamental importance of understanding dark energy, defining the optimal mission for determining its nature may be among the most important astro/particle physics tasks of the next two decades.
