- Launch Date: March 14, 2006

Launch Window: 8:57 a.m. to 10:19 a.m.

Target Drop Time: 9:02 a.m.

Nicely done John. I'll make this the live launch thread as it's a good opening post of reference.

Also note the pre-mission thread: http://forum.nasaspaceflight.com/forums/thread-view.asp?tid=1158&posts=21#M24920

But no press kit as far as I can see? Does anyone have one?
I assume the planned drop point is the usual 36.0N 123.0W ?

Mission delayed 24 hrs to Wednesday due to predicted unfavorable weather conditions on Tuesday. 80% chance of favorable weather on Wednesday.

We can live with that.

Thanks. I see the link on the NASA HQ site now. Could have sworn it wasn't there
when I looked this morning :-). Oh well...
 
Some nice things in the press kit. Spacecraft dimensions 0.53m dia 0.48m high stowed, mass 25 kg fully fuelled. Planned orbit 300 x 4500 km x 97 deg.
Drop at 12.2 km altitude.
Timeline: Drop+0:05 stage 1 burn, +1:17 stage 1 burnout at 55 km, +1:31 stage  2 burn at 72 km, +2:11 fairing sep at 115 km, +3:06 stage  2 burnout at 156 km,
+5:03 stage 3 burn at 283 km, +6:11 stage 3 burnout at 302 km, +9:31 ST5-FWD sep, +12:41 ST5-MID sep, +15:51 ST5-AFT sep.
GSFC has in-house prime contractor/integrator role, as far as I can tell.

Some things not in the press kit, but maybe someone here knows:
 - Dry mass of spacecraft (or equally good, mass of propellant loaded)
 - Drop point coords
 - Nominal delta-v of stage 3 burn
- Span of spacecraft once boom is deployed (I guess about 1.0 meter)
- WHAT ARE THE THREE S/C GOING TO BE CALLED ONCE ON ORBIT? The only hint in the press kit is the
diagram calling them FWD, MID and AFT. But maybe they have serial numbers like S/N 1,2,3? and maybe they will be
given individual names (Larry, Curly, Moe? :-)). Any clues?

GN2 is the propellant

NASA'S ST5 LAUNCH POSTPONED DUE TO WEATHER FORECAST

Predicted weather conditions postponed Tuesday's scheduled launch of
NASA's Space Technology 5 (ST5) spacecraft. It will launch Wednesday,
March 15, at 9:02 a.m. EST.

The forecast improves on Wednesday with only a 20 percent chance of
not having acceptable weather.

ST5 launch coverage on NASA TV begins Wednesday at 7:30 a.m. EST. NASA

Are you sure? , 56 lbs is the fully fuelled mass according to the sources I've seen, not the dry mass.

For the size of the spacecraft, how much GN2 do you think they can compress to really make a difference?  There isn't a "dry" or "wet" mass, since it uses GN2.

Ahh, good point. Wasn't thinking straight.

Everything looking good for a a launch today. L-1011 take-off is planned for 8:04 am EST, 1304 UTC. Weather is predicted to be 100% go at Pegasus XL drop time.
