Most Shuttle launch times seem to be marked >as EST (eastern standard time ??) (or was it EDT !) so how come CDT here. Oh. Sorry. I tend to forget about overseas readers. KSC is in the Eastern time zone, but the Johnson Space Center (Mission Control) along with myself am in the Central zone. The charts I was working from were JSC charts, so the times were GMT and Central. The zones in the continental U.S., from east to west, are Eastern, Central, Mountain, and Pacific. Central is one hour west of Eastern. Add on top of that the fact that we are now in daylight savings time (thus the D in "CDT")...... To go from GMT to CDT (that's DAYLIGHT time), subtract 5 hours. So the 4/28 launch window opens at 18:24 GMT. >Also, I would be interested in the other launch windows if you don't mind >typing in the lot. If I have some time. I have about a third of it typed in now. But the whoe chart is quite a bit: 30 days worth. And the functions are not linear, so I can't just write a program to do it (in fact, they're probably not even polynomial). William LeFebvre Department of Computer Science Rice University
