jcm - 13/3/2006 8:04 AMBut 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 ?

jcm - 13/3/2006 5:36 PMThanks. I see the link on the NASA HQ site now. Could have sworn it wasn't therewhen 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 thediagram calling them FWD, MID and AFT. But maybe they have serial numbers like S/N 1,2,3? and maybe they will begiven individual names (Larry, Curly, Moe? :-)). Any clues?
jcm - 14/3/2006 8:01 AM| 56 lbsAre you sure? , 56 lbs is the fully fuelled mass according to the sources I've seen, not the dry mass.

There isn't a "dry" or "wet" mass, since it uses GN2.
