The Final Reports for both the Starshade and Coronagraph Exoplanet Probe Studies (Exo-S and Exo-C respectively) have been publicly released. These reports examine the science possible for exoplanet direct imaging missions that can be launched as early as 2024 for around $1B dollars. These concept studies make a compelling case for affordable direct imaging missions, will motivate technology investments and are expected to provide valuable information to the exoplanet community for the design of mission concepts leading to the next Astrophysics Decadal Survey.
The reports capture the science cases for both architectures, provide technical details on one coronagraph and two starshade mission designs, and explain the plans for advancing critical technologies in time for mission starts within this decade.
