Hearing rumbles from multiple sources that NASA will announce very soon which spacecraft they will fly; SpaceX Dragon V2, SNC Dream Chaser or Boeing CST-100. One report says they will pick 2 spacecraft with full funding for each,

Charles A. Lurio @TheLurioReport
NASA Comm. Crew CCtCap award likely on 22 or 29 Aug.: allows finalization of contracts before likely Contin. Res. (CR) for next FY at 1 Oct.

Charles A. Lurio @TheLurioReport
Also: CCtCap probably two "full" awards, no "half;" depending on $ avail., options to extend now/new active phases under consideration.

Keeping ears to the ground....

I hope its the Dragon V2 and Dream Chaser, they look the most interesting out of the two.

Likelier to put _cautious_ bet on SNC in CCtCap than whether SpaceX or Boeing wins other contract. Dream Chaser a 'fan favorite' at NASA/ULA

Charles A. Lurio @TheLurioReport
Conflicting reports tonight - CCtCap announcement on 22 August or slip to September for Congress notification requirements./I ask:or other?

Never been all that impressed with Dream Chaser.  Seems like it limits what we can do in space.  What is going into to choosing a craft?  Does it just have to dock with the ISS or they hoping they can do more with it?

There are numerous criteria, ranging from cargo capacity and safety to the business case - NASA wants a spacecraft with commercial viability so they aren't the only ones paying to keep it flying. The criteria are scored from red (bad) to green (good).

Commercial uses can range from flying missions for companies like crews & cargo to Bigelow Aerospace commercial space stations to flying missions for other countries or the US military.

In the last business case evaluation Dragon V2 was green and both CST-100 and Dream Chaser yellow.

Since then SNC's Dream Chaser is being looked at by both ESA and JAXA (Japan) to fly missions for them. DC is also relatively inexpensive to build and operate. This offsets the cost of its primary Atlas V HR launcher.

Boeing's CST-100is having trouble making the business case because of both design choices that drove up costs, one being an expensive Apollo-like disposable service module and another the high cost of it's primary Atlas V HR launcher.

Dream Chasers main advantages over the capsules are It has a very low G re-entry at just 1.5 G, a wide cross-range (can land 1,500 km to either side of its orbital track - basically any major airport) and its propellants are "green," nitrous oxide and propane. The low-G entry would be useful for medevac and sensitive experiments.

With the way Boeing has been repeatedly saying there is no business case for them without NASA... how the hell is their business case evaluation orange and not red :s

They've retreated a bit, saying they may continue by joining the COTS2 cargo competition if not selected.

The problem with that is their small hatch opening and lack of an pressurized cargo bay like Dragon's trunk. Adding the latter would have to be a service module extension, and that would cover the circular solar panel at the bottom of the service module.

ISTM by having that disposable service module instead of integrating it like DV2 & DC they've painted themselves into a corner.

We'll see.

Owwww.... HARSH!! :ninja:

CCtCap: Boeing CST-100 called 'simpler' - but a "powerpoint tiger?:" SpaceX way ahead on design and test of real hardware for Dragon V2.

Well, it is true imho. I mean, what have we seen from Boeing other then some mockup's that were dumped into a pool or outfitted with blue leds :p

Maybe they should fund the cst-100 since both the dragon and the dream chaser seem like they will get funded by other means. So then they end up with 3 instead of 2.

That wouldn't seem to follow the program guidelines published at the start. Very Darwinistic.

Just so we all know what happens after the coming CCtCap (commercial crew transportation capability) downselect,

>
Beginning in summer of 2014, when awards are anticipated for one or more contractors, CCtCap efforts will be focused on developing, verifying and validating an integrated system that is safe for crew transportation. A CCtCap contractor also will plan, manage and execute long-term production and operational plans for its crew transportation system (CTS).
>
>
The certification portion of CCtCap will include a contractor completing at least one crewed flight test to the International Space Station. NASA plans to award at least two and up to six additional post-certification missions during the CCtCap period of performance prior to a follow-on space station services contract.

Sounds like NASA is waiting for Congress to pass the continuing budget resolution before flying home to campaign for the November elections.

No doubt they'll wait for everyone to be at 30,000 feet to announce the winners so Shelby etc. can't do anything stupid.

That vote is set for Thursday.
