Well, direct wouldn't be totally "direct."

The name "Direct" comes from "Direct Descendant of the Shuttle" (same
SRBs, same ET diameter, as opposed to FSB and 33 ft core Ares), not
the mode of reaching the moon.

A strong point of confusion, nevertheless, and one that I've argued (to
no avail) to the DIRECT team that they should fix. It's not a bad
architecture, if the objective is to minimize transition costs from the
shuttle, but it is being sold so ineptly that they've pretty much
ensured they'll never get a fair hearing until at least 2009, by which
time it will be too late. If their prime objective is to make themselves
public martyrs, they are succeeding beyond their wildest dreams.

Jorge:

You may have discussed this previously but i missed it so please
expound on how you think it should be sold vs how they are trying.
