[sci.space] Will ATF Detect Earths?

DIETZ@slb-test.CSNET.UUCP (11/22/86)

According to what I've read, the ATF will be able to detect
earth-like worlds out to about 30 light years, and gas giants
out to about 1000 light years or so.  Maybe Gary meant that ATF
will not be able to get a statistically significant sample of
earth-like worlds?
