Quote from: Tea Party Space Czar on 07/06/2012 02:35 amPeople here need to realize what is happening... its called competition. It is a very good and healthy thing. I, personally, like some of the comments about cost launching from LC-39, the VAB, ect. Those are some old and very expensive pieces of infrastructure. If ATK can sell a product to the public and NASA at a price that is competitive in the free market, why should we not embrace this? The fact that ATK is pushing companies like SNC, ULA, and SpaceX is a good thing. We, at TPIS, are quite aware of the money ATK received. $1.8 billion is a lot of money. If they can develop a system on their own dime, using their own funds, and finding new investors, good for them.Hating just to hate is childish. There are a lot of things you can say about how contracts are awarded, but competition is good. We will see what happens. Would you ride Liberty if given the chance?Respectfully,Andrew GasserTEA Party in SpaceOf course, we want ATK to compete with others. But Chris article suggests that ATK is getting bonus points for launching from KSC. The fact that their proposal has a lot of commonality with SLS and MPCV is also seen as a positive. The fact that they have political clout and influence in Congress and within NASA is also seen as a positive. None of this should matter in a free market.

The real question for the liberty rocket is: Will Safran Snecma and Astrium be able to get the Vulcain 2 engine to air start reliable? I think that at least two times a Ariane 5 launch was aborted because there were problems with the Vulcain engine.

It has become a very reliable engine. Kudos to SNECMA and it's contractors for getting it there after the failure of the first Ariane-5 ECA mission.To answer your question: yes, they will be able to get the Vulcain 2 engine to air-start reliably. Basically they already have. A direct result of the investigation and improvements made after the failure.

A direct result of the investigation and improvements made after the failure.May I recall you to VA-201. http://forum.nasaspaceflight.com/index.php?topic=23773.0On May 30th 2011 the Ariane 5 launch with Yahsat 1A and Intelsat New Dawn aborted shortly after main engine ignition. Wasn't it the case that an actuator (that would pivot the engine) didn't work normally. If this would have happened with an Air-start, the mission would have failed, isn't it?To this failier (abort) I was referring.
I'm trying to get a few things sorted out.Wikipedia says Liberty is priced at180 million $ per launch and has a payload capacity of 20,000kg. Are these numbers correct? does this price represent the cost to NASA or some sort of a minimal order price ? ( like Falcon 9's advertised price). Honestly if it's the bare minimal price (no integration work etcetera) I can't see how they think they could compete with anyone. Do you?
Understood, although while companies were free to submit proposals for any and all, the CCDev-2 focus was clearly on spacecraft or related systems. I can't believe ATK was not aware of that. [snip]That strongly suggests something significant changed in a relatively short period of time recently. I appreciate that you are limited as to what information you (or any others) can provide, thus my questions... which I hope ATK will address when Chris interviews them, as it seems the Liberty spacecraft is the big question mark (at least for me).
IMHO, "political capital" is a horrible reason to make a decision. I will not accept this commonly held notion that it is "just normal, so we shouldn't get upset." No, it's not normal, it's corruption.Those who say that ATK's only real chance is the use of political capital are essentially acknowledging corruption as a viable option. It's not a viable option.So, we ought to judge the proposal on its technical merits, not on political connections, because every time we take into account political connections, we are implicitly giving legitimacy to corrupt practices that puts self-serving politicians ahead of the interests of our great country.ATK apparently believes they have a proposal that's got technical merit, and it's on THAT that they should be judged. Judging it on political merit is just an encouragement to corruption, and I won't stand for it. The point is to have a domestic, low-cost, financially sustainable, safe crew transport option as timely as possible. Those are essentially the things that Liberty should and will be judged on, NOT on "political capital."(And if "political capital" is what it is judged on, then we should FIRE THOSE POLITICIANS NOW, and prosecute them for corruption.)So, I will choose to judge the proposal on technical grounds.That is all.
Now then, moving on to topic.Regarding the LV and the article. I think most of us are not pleased with this vehicle. That is obvious by the sort of comments that always seem to populate these ATK threads. There are saftey issues with it, I had a somewhat short lived thread (because I injected opinion) about the abort issues, but there are many more around.The basic point here is that, for all the problems with the stick, it still is just one vehicle. Its not even being funded by NASA at this point. There are many more out there.Now if this vehicle was chosen over, say, SpaceX or DC I would be upset. But we are not there yet and its highly unlikely, IMO, that this will happen because guess what: the NSF community is not the only people who have issues with ATK. I am sure there are people within NASA management who don't want to fly crew on it either.The bottom line is we wait and see, and follow development of the system in the mean time. Continuously bashing ATK will gain us nothing.

Continuously bashing ATK will gain us nothing. Actually right. The next round of NASA funding goes to the companies that are closest to completion. SpaceX, Boeing, and SNC are now, or soon will be at the CDR level, and are bending metal / composites, and have actual production / operational plans in place. Is there any hope for ATK / LM to even be close to the PDR level by 2014/5 with both the launcher and the capsule ? They can continue funding this with their own money if they wish, but I don't see how it would be selected by NASA given the agreement on the 2.5 funded companies for this round. Some people can have all the ATK hate they want. I'm sure that if ATK were offering free rides on the LEGO rocket, they would certainly get in line.
Quote from: daveklingler on 07/05/2012 07:45 pm booster redesigns are well-documented.What redesigns did ATK do? They were not in charge of Ares I, NASA was the system designer, ATK only provided the first stage.

In any industry, it's always more profitable to let the little guys develop the market while pumping all their money on R&D. Then the big guys step in and mop up. Whether or not it works out that way, it's entirely possible that's the way the established companies are playing it.
