Detailed simulations are presented of the longest exposures on representative fields that will be obtained with the Hubble Space Telescope, as well as predictions for the numbers and types of objects that will be recorded with exposures of different durations. The Hubble Space Telescope will reveal the shapes, sizes, and content of faint, distant galaxies and could discover a new population of Galactic stars.
