摘要

ACCESS is one of four medium-class mission concepts selected for study in 2008/9 by NASA's Astrophysics Strategic Mission Concepts Study program. In a nutshell, ACCESS evaluates a space telescope designed for extreme high-contrast imaging and spectroscopy of exoplanetary systems. An actively-corrected coronagraph is used to suppress the glare of diffracted and scattered starlight to the levels required for exoplanet imaging. The ACCESS study asks: What is the most capable medium-class coronagraphic mission that is possible with telescope, instrument, and spacecraft technologies available today?
