I've also heard that the Barnard's star data has been written off as
spurious.  A new interferometer is being built somewhere back east for
high precision astrometry.  The device should collect in a few hours
data that would have taken a year by previous techniques.  Accuracy is
a few milliarcseconds, good enough to detect Jupiter sized planets
around nearby stars.  The shuttle could orbit an interferometer
accurate to microarcseconds, which would allow the detection of earth
sized planets out to many light years, and Jovian planets out to great
distances.
