Recent Hubble Space Telescope images have revealed HH 30 to be a prototype young stellar object {YSO} system possessing an optically thick circumstellar absorption disk extended perpendicular to highly collimated bipolar jets. The visible disk is 450 AU {3.2"} in diameter and shows a resolved flaring profile consistent with accretion disk theory. This system is the first YSO disk ever observed at 14 AU resolution, and the first viewed close enough to edge-on that the vertical structure of the disk is clearly visible. We propose to build upon our initial results with Cycle 6 observations that address the following goals: 1} Further resolve the system by observing with the Planetary Camera, to better constrain the disk flaring profile; 2} measure the polarization structure of the nebulosity for comparison with multiple scattering models; 3} produce a much better map of the nebular colors via deeper imaging at short wavelengths; and 4} define the time history of the jet flow and the outer extent of the disk nebulosity via deep R band imaging. These studies of HH 30 offer a unique opportunity to expand understanding of accretion disk structure, and thereby constrain the disk evolution processes which profoundly affect theories of the origin of the solar system.
