This is a scientific strategy for the detection and characterization of extrasolar planets; that is, planets orbiting other stars.  ...  As such, it maps out over a 15-year horizon the techniques and capabilities required to detect and measure the properties of planets as small as Earth around stars as large as our own Sun.  ...  Likewise, if the astrometric mission fails or turns out to be infeasible, pursuit of space-based direct detection in the final time period would require a sufficiently large η ⊕ based on COROT and Kepler  ...
