<sarcasm> How impressive. <end sarcasm>  He wasn't the only one making
those predictions.  Does this somehow give his other opinions more weight?

Interesting, yes.  I'm not sure I would say "cogent" without first talking
to people like the solar astrophysics types (remember the Skylab Solar
Telescope and the Solar Max repair?), not to mention the lunar geologists.

If one's priorities are short-term gain (be it financial or scientific),
then of course one gets upset about long-term investments.  Some would
question those priorities, however.

It is also dishonest, not to mention foolish, to pretend that cutting
back manned spaceflight would boost planetary science.

Agreed, but please observe the word "need".  These things would indeed
be useful.  (I note that most of them don't seem to be high priority for
the space-science bunch.)  But they are in no sense prerequisites.
