The following link contains the slideshows from NASA's Ares V Astronomy Workshop from april 26-27, 2008.
Pretty cool stuff showing the interest in 8 to 16 meter telescopes launched from Ares, paired with a sun occulter, capable of imaging exoplanets. Even some pie-in-the-sky talk of the Planet Imager, using linked Ares launched mega-scopes.
