meiza - 16/5/2007 6:21 AMCould one try to move to launching multiple small sats at one time with EELV? 1. Or are the orbital parameters too different, or 2. is it too costly, schedule wise? 3. Deep space probes need dedicated launches anyway it seems.
CFE - 15/5/2007 10:31 PMThe smartest way ahead for NASA would probably be paying for the remaining development on the EELV-Small. Delta IV with Delta II's second stage shouldn't be too hard to do. I haven't seen any concept art of Atlas V-Agena, though. Would ULA still have the tooling to produce an updated Agena?

publiusr - 21/5/2007 3:28 PMHas anyone ever played with the concept of Delta II cores as strap-ons themselves? I think Hujsak once wrote about something similar in one of his books...
josh_simonson - 21/5/2007 5:00 PM>I will probally draw several lightening bolts here, but I always thought lockheeds switching everything from the Atlas II/III to the Atlas V was a beter marketing plan than the boeing keep the Delta II and Delta IV. Doing that drove up the price of the Delta II while eating into the Delta IV volume thus driving up the Delta IV price.The leap from Delta II to Delta IV was much farther than from Atlas 3 to Atlas V. Until ULA the Delta IV's future hadn't been 100% certain either, whereas the Atlas V has been in better shape, buisnesswise. If Delta IV had been a dud Boeing would be glad they'd kept Delta II.

Jim - 21/5/2007 4:46 PMAtlas II/III & V are almost the same marketDelta II and Delta IV are not the same market. Delta II costs are unrelated to the D-IV program. Delta II would still be in the same situation as it is now, if there was no D-IV
Analyst - 15/5/2007 4:34 AMQuoteSkyrocket - 15/5/2007 11:25 AMbecause there are not enough customers: Delta II will be no longer economic, when it is used only for a handful of NASA launches.And a replacement will have more customers? I don't buy this logic.Analyst
