Overlap in Nasa-ESA exoplanet space missions?
I'm curious about the overlap between Kepler and Eddington missions. The main difference to my non-expert eyes is that Eddington will look at more stars, but start that search 3 years later.
Both agencies have an identical agenda: first, space based transit detection (Kepler and Eddington), then space astrometry missions for exoplanet detection (SIM and Gaia), then direct detection of terrestrial planets (TPF and Darwin). Does this make sense? Should they eliminate some duplicative missions, and devote the funding to accelerating the next, more advanced stage?
