a
» Continue exoplanet survey operation to produce an initial catalog of planet candidates
» Execute a follow-up observing program that targets planet candidates with radius <2.5 Re
» Make a determination of ηe » Facilitate community participation» Build and maintain a legacy archive and
support community use of the Kepler data» Support community observations with Kepler

» CoRoT, Kepler and MOST have bestowed a legacy for testing and furthering theories of stellar structure and evolution across the HR diagram
» CoRoT is requesting an operations extension through 2015
» Kepler will operate until at least 2016» All existing Kepler data become public on Oct 28, 2012» All future Kepler data will be publicly available without
proprietary period» New Kepler targets can be added through the Guest
Observer Program
