Quote from: KelvinZero on 06/16/2010 08:45 amBut what compromise would bring us closer to a permanent base on the moon? Who is pushing for it? As far as I can see, a SHLV without Orion and Altair puts us further from the moon, because we will be eating money just standing still. Im not the brightest guy here. There seem to be actual NASA people here who think a SHLV is a good compromise. What am I missing?You are missing that Orion would be re-funded and completed as the default US human crew transfer vehicle. Because a pure-SDHLV is cheaper (by at least an order of magnitude) than the Ares Launch System, it leaves funding for mission modules that CxP could not because it was committed to launch vehicle development. Because the SDHLV is not so extreme in its costs and performance, it can be used for LEO-only missions and early Orion-only pathfinder missions. CxP called for two distinct LVs (debate the exact requirements but this is indisputible). One was only good for launching crew to LEO and could do nothing else. The other could not go into serious development after ISS retirement. This is not the case for the SDHLV. Its core is common between LEO and BEO versions, and requires a far less costly development program to gain BEO capability (only the upper stage rather than a whole different core, upper stage and engine development program). The major advantage over Ares-V (IMHO at least) is that it does not have to wait until the BEO elements are complete to have a useful purpose. It can assist in ISS support and even carry out other LEO and even possibly GEO missions.An SDHLV would allow a phased return to the Moon, starting with orbital missions, then excursion landings and later going on to long-duration survey stays. It is also adaptable for exploration of the rest of the Inner Solar System. The lunar outpost is still too early in conception to be certain of its requirements, but the basic SDHLV concept is flexible enough to handle most reasonable requirements for that application too.

Ok.. so this isnt a compromise is it. Its a do over. But fair enough.
I guess I just cant believe the same organisation can do it ten times cheaper this time.

Unfortunately for the President, he doesn't actually control any of the money. So this is going to be very-much a one-sided fight: 533 vs 1.That's why some folk are describing this as a "backfire".
The popular opinion seems to be that all of this is going to end with a CR. Basically passing this whole issue off to the next Congress. However, how does a CR prevent NASA from working on FY2011? Technically the law of the land right now is Cx still, yet that hasn't been followed too closely. With congress more worried with elections in the next few months, who is going to stop NASA from continuing to shut down Cx + Shuttle?
Quote from: KelvinZero on 06/17/2010 12:34 amOk.. so this isnt a compromise is it. Its a do over. But fair enough.I think it was shaping up to be a "compromise"....They certainly can't do the same thing 10 times cheaper. Ares-I is dead. And Ares-V is unaffordable without Ares-I. So those plans are gone.But there are plenty of different things which can be done instead. Almost all of which which require much less work, in order to achieve the same basic results.The problem with the old ESAS plan was that it was never supported by the data -- merely unsupported opinions from its originators, who were unfortunately put in charge.The data actually pointed a different way and they ignored it, decried it and fought it tooth and nail to get their own pet project in place instead.Remove all the B.S., and you can start to make much better decisions based on real, substantiated data. That's how you can identify all the savings you need.Ross.
Now it is going to be a straight fight.Unfortunately for the President, he doesn't actually control any of the money. So this is going to be very-much a one-sided fight: 533 vs 1.

It was to pay for Ares 1, so if continuing resolution continues, while the accounting issue continues, it means that Shuttle shuts down while Ares 1 shuts down.Am I reading this right?

A CR, unless it contains specific language to the contrary, would carry over the FY10 amounts for both shuttle and CxP.I could be wrong but I don't think that appropriation legislations are that specific. They just have headings like space operations or exploration. I would expect that a lot of leeway is allowed under these headings.

Yes, unless Congress inserts a "provided that..." clauses. Example from 2009 shown:
