One of the advantages of the Ares IX test seems to be an easier ability to
re-cycle the countdown on holds. However, a lot of what was done for the
Ares IX test is not representative of the actual manned Ares I. When you
add the liquid fueled upper stage and the Orion capsule systems how easily
will the launch countdown re-cycling be? And what will be the countdown
hold times? T- 4 minutes was the cycling used on the I-X test, but does
anyone know what the cycling will be for the actual Ares I?
