NSPD-40: ask and ye shall receive
here is a description of NSPD-40 - US Space Transportation directive and the new rules for NASA Exploration.
Actual text of NSPD-40 is not published.
Now if we just knew the text of NSPD-31 - which is allegedly the directions in Space Science one (a "Security" directive?),
well, then we'd know where we're supposed to be going, eh?
