THE SEARCH FOR LIFE IS ONE OF THE NEXT GREAT CHALLENGES IN ASTRONOMY. NASA'S 30-YEAR ROADMAP FOR ASTROPHYSICS ENVISIONS A SEARCH FOR SIGNS OF LIFE IN THE ATMOSPHERES OF EARTH-LIKE PLANETS USING SPECTROSCOPY FROM A LARGE SPACE TELESCOPE. NASA IS NOW PURSUING THREE FLAGSHIP CONCEPT STUDIES THAT WILL ENABLE THIS SEARCH (LUVOIR HABEX AND OST). ESTIMATES FOR THE NUMBER OF EARTH-LIKE PLANETS SUCH A MISSION CAN DETECT AND CHARACTERIZE INCREASE AS THE SECOND POWER OF THE APERTURE MOTIVATING TELESCOPES LARGER THAN JWST THAT MUST BE SEGMENTED TO FIT INTO ANTICIPATED LAUNCH FAIRINGS. IT IS CERTAIN THAT A MISSION CAPABLE OF DIRECTLY IMAGING EARTH-LIKE EXOPLANETS WILL INCLUDE A CORONAGRAPH EVEN IF STARSHADES PROVE TO BE EFFECTIVE AND FEASIBLE. THUS THE TECHNOLOGICAL CHALLENGES PRESENTED BY HIGHPERFORMANCE CORONAGRAPHY ON SEGMENTED TELESCOPES MUST BE SOLVED IF WE ARE TO MOUNT A STATISTICALLY ROBUST SEARCH FOR LIFE ON OTHER WORLDS. FOR THREE YEARS OUR GROUP HAS BEEN AT THE FOREFRONT OF DEVELOPING HIGH-PERFORMANCE CORONAGRAPH TECHNOLOGY FOR SEGMENTED APERTURES. WE HAVE BUILT A ROBUST FLEXIBLE TESTBED HICAT FOR OUR APODIZED PUPIL LYOT CORONAGRAPH (APLC) APPROACH TO SEGMENTED APERTURES. BY OPTIMIZING INDIVIDUAL COMPONENTS WE HAVE MATURED THE TECHNOLOGY TO TRL 3. BUT FOR A SEGMENTED TELESCOPE AIMING TO ACHIEVE 1E-10 STARLIGHT SUPPRESSION THE STABILITY OF THE WAVEFRONT DELIVERED FROM THE TELESCOPE PRESENTS SPECIAL CHALLENGES TO CORONAGRAPH PERFORMANCE. THE TELESCOPE AND CORONAGRAPH MUST BE CONSIDERED TOGETHER AND THEIR TECHNOLOGIES ADVANCED AS AN INTEGRATED SYSTEM.
