We propose to continue a program to map the interstellar medium in three dimensions. Our technique uses infrared echoes from the supernova Cas A, which we discovered during In-Orbit Checkout. We have observed the echoes every six months since, observing the changes in the patterns of heated dust as the light pulse from the supernova propagates through the surrounding ISM. We have developed methods to invert this series of snapshots of planes in the ISM into three dimensional images. By the end of the Spitzer mission, our 3D images will have a depth of 1.5pc at a resolution of about 0.1 pc. This detailed information about the structure of the ISM will have important applications in understanding extinction in dense regions, the radiative transfer and heating of such regions, and in how the ISM fragments, for example to form stars.
