How can you have a launch window when you are only going 28 miles up and
then down again?

All launches have launch windows, just this one is not limited by
planetary or rendezvous constraints.
It takes into account launch crew fatigue, airspace restrictions,
range assets and crews availability; and vehicle limitations
It is |

Ever think of other traffic around KSC (air-traffic and shipping etc).
NASA can only the required air-space and sea-space (correct word?)
closed for a abount of time.
Today they could have it closed up to noon EDT for ARES launch.
If I'm not wrong, the air-space and the area on the Atlantic are closed
from 8 am EDT till noon, EDT. |

Range safety. The area covered by the launch safety zones is also
home to some very busy air- and sea- lanes.

And in fact had a cargo ship apparently intrude into the restricted area.
You may also want certain light conditions for cameras and tracking, etc.

Could someone summarize the differences between the Arex1X SRB and a
normal Shuttle SRB ?
Do they have the same fuel, fuel pattern in the tube etc ?
Are the nozzles the same, with the same actuators and range of movement
for the nozzles as a shuttle one ?
And when/if they go to 5 segment SRB, will they just add the extra
segment, or will they have to beef up the nozzle systems because they'll
need more torque to move nozzle because of extra thrust ? |
