Which actually would not be the worst option, as SpaceX would still sell crew Dragons for purely private flights. That probably cannot be said for the other two. Just selecting SpaceX and giving no money to anyone else would effectively create a monopoly.But Dragon will still probably fly a crew first. As strange as it to think about, they are basically the established incumbent, and Boeing and SNC are the insurgents.
Yeah right. Ignore the selection rules. Punish the small company that is the leader in the race and reward the huge company that is behind.
I am worried that there will be a down-select to one, and the winner will be Atlas5/cst100, with the reasons being political and not technical or economical.
As I read it, what simonbp is saying is that if the field is narrowed to a single company, it should not be SpaceX, because SpaceX will likely carry on even if it is not selected.
Maybe it's just me but I have a lot of trouble with the notion that the money should go to a competitor less interested in the advancement of the state of the art and less likely to continue if they don't get it and arguably less far along (despite what milestones are completed numerically).

For the last couple of decades, Boeing has been a contractor that wouldn't lift a finger unless it could bill the government for it. They appear to have put some skin in the game for CST-100, but old habits die hard.

The award(s) will go to the offeror(s) who can meet the requirements at lowest cost. The rules are quite specific and explicit, and spelled out in both the RFP and FAR rules and regulations. That's not to say some contendor's might not lodge an objection, but to assume or presume that NASA will contravene the rules is dubious at best (there would be hell to pay). Sure, political or other pressure could be brought to bear to influence to change/delay selection, but IMHO that would leave so many tracks that the entire process would be back to square one. I don't think that is in anyone's interest, and I would hope and expect all of the contender's recognize that.
Regardless of one's opinion of Boeing and its committment, or which company is ahead, etc, or which is "coolest," or most advanced/ progressive/ cutting edge, the fact remains that a major consideration is development of a vehicle with reliability and proven capability. Boeing, by virtue of being "Old Space" with its considerable history, and its approach of applying known capabilities and systems for CST, can make a pretty heavy duty argument as the logical choice in a tight budget environment and amidst residual sensitivity over the STS losses (and resulting program fallout). It is NOT just who delivers fastest and at lowest cost. It is also who provides for a confidence level that their vehicle won't kill a crew as well as produce a vehicle and support services to that vehicle to ensure a reliable space transportation system going forward. It is difficult to objectively dismiss Boring's advantages in this aspect of the competition.
Ludicrous. Spacex may have an operational vehicle (which is not the same as the pending crew vehicle) but they have zero history with crew. Boeing is unmatched currently in this area. And blaming Boeing for STS lesses and citing it as a reason to not consider is just as ludicrous. Just as we learned from loss of Apollo 1, Old Space learns from its history, good and bad. What happens if Space X loses a crew? They have a "perfect record" with crew, as does any company that has never clown a crew.
And loss of orbiters was not the fault of Boeing... An absurd argument.
Quote from: Go4TLI on 02/06/2014 03:12 pmOne of the arguments many liked to make against shuttle was the "all the eggs in one basket" one. I'm curious about something. Many of those on here are now proclaiming Dragon/F9 for everything (not totally surprised on that by the way). So I would like someone to walk me through the logic. If, more likely when, something happens and either Dragon and/or F9 are grounded for some time, crew capability is lost for some measure of time as well as half the cargo supply. And let's face it, these are smaller vehicles so more frequent runs are needed. And they don't grow on trees so Orbital just can't pick up the slack. So what happened to the redundancy argument used?I am totally with you on that one. I do want that redundancy too (as well as competition), which is why I want more than one commercial crew option funded.

Everyone seems to think it's very likely that if there's one crew launch system only, at some point it will have a mishap and then be out of service for an extended period.If that's true, then having two systems only gives the illusion of safety. You're safer having only one system and continuing to use it even after a mishap, even if you haven't reached the root cause yet. That's because our assumption is that there are very likely to be mishaps. So if you have two vehicles and you stop using one because of a mishap, the other is still likely to have serious problems you haven't uncovered yet. Having one vehicle that flies more often gives you only half the total number of root cause problems you have to find. So, the total number of fatal accidents per flight is going to be lower with one vehicle than with two, even if you stand down one of the vehicles after each mishap.Of course, having only one vehicle and standing down after a mishap until the root cause is identified gives even greater safety. But, under the assumption that mishaps are likely, if the choice is between two vehicles and standing down after each mishap or just one vehicle but no stand-down, the one vehicle with no stand-down is the safer option.In other words, having two vehicles is just so much less safe than having only one that even not standing down after a mishap with one vehicle doesn't decrease safety as much as having two vehicles.
