NASA's plan for a large-scale observatory to directly detect and characterize terrestrial planets has been significantly delayed by funding shortfalls. It appears more likely that a smaller, focused extra-solar planet mission could fly in the next decade. Mission modeling studies show that a 1.5 m aperture coronagraphic telescope could detect and characterize a handful of Earth-like planets and many Jupiter-class planets. The technology for the giant-planet portion of the mission, including a contrast ratio of 2x10^9 in 10% bandwidth light, is in hand and no fundamental roadblocks remain. External occulter technology is less mature but once developed a formation-flying occulter could join the telescope in orbit to form a powerful exo-planet characterization observatory.
