Exoplanet Exploration Program

In January 2013, the NASA Astrophysics Division initiated the formation of two Science and Technology Definition Teams (STDTs) to study probe-scale (cost less than $1B) mission concepts for the direct detection of extrasolar planets orbiting nearby stars. One will study a concept based on a telescope with an internal cononagraph to generate the ultra-high contrast images needed for planet detection. A second study will use a pair of spacecraft flying in formation - a telescope and an external occulter (starshade). The STDTs are supported by a Design Team staffed by the Exoplanet Exploration Program. Final Reports from the studies will be due by January 2015.
