CCDev2 Briefing tomorrow, via SpaceXer:http://twitter.com/SpaceXer"Interested in the future of human spaceflight? SpaceX is joining a NASA press briefing on CCDev Thursday"http://www.nasa.gov/mission_pages/shuttle/news/134_hours_events.html
April 28, Thursday11 a.m. - Commercial Crew Development Briefing - KSC (Public, HD and Media Channels)
Latching on to the massive popularity of STS-134 a bit, aren't they? Don't blame them, but I hope they all respect Shuttle and their legacy at these events.
Knowing the actual employment of several and the planned employment of several it would seem that the slope to creating them is much more shallow than initially claimed.

Radiation shielding = water wall. Seriously, it's not that difficult. You just need mass. If you have enough to spare in your mass budget, it's not a difficult design problem.The two leaders of CCDev2, CST-100 and Dragon, could both be used for BLEO. CST-100 may need a slightly thicker heat shield (and maybe it doesn't), but that's not at all a problem, considering it's an ablative heat shield. CST-100 uses the same shape as the Apollo capsule. There's absolutely nothing inherent in the design that means you couldn't use it for BLEO. And same thing with Dragon crew... And I should note that the LAS for Dragon Crew is integrated, meaning it's part of the spacecraft.
CST-100 is purely designed for LEO only. It is designed purely as a space taxi. It runs on batteries. Once the batteries are done, it's done. There might be a CST-200 or CST-300 on the drawing board, but lets keep it to vehicles that might be ready this decade. We have no idea if the F9 can lift a Dragon capsule with the additional mass. Heck, we don't really know if the F9 can lift a Dragon loaded with anything heavier than a wheel of cheese. Then this additional mass requires the development of a more powerful LAS. All this extra weight, and you have a vehicle that requires the FH, just to get into LEO. Now you no longer have a vehicle that costs $20m per seat.

The rest of the CSF nonsense is getting extreme. If anyone else said this about anything, would they be viewed as credible? It sounds like a amazing people talk honestly. Does they point to any tangible piece of data or evidence that we are on this "brink"? No. I mean, for goodness sake, who doesn't want commercial to succeed but at the same time all the cheerleading without EVER talking about many of the real pitfalls will seemingly strain their credibility. For example, where are all those jobs they predicted would be created and mentioned here again? Knowing the actual employment of several and the planned employment of several it would seem that the slope to creating them is much more shallow than initially claimed.I wonder what else may be too good to be true.....

I don't think that they are trying to be disrespectful towards the Shuttle. I am much more worried about commercial crew getting its funding reduced than the SLS/MPCV. So getting the message across is important.
