Does anyone know what the current status of the fifth Crew Dragon capsule is? The last I knew was that it would be ready to fly next year. Thanks!

[zubenelgenubi: Post merged to this thread.]

This was asked at the Crew-7 press conference on Monday and the brief answer was still scheduled for 2024.

From a report of today's ASAP:

Quote from: Gene J. Mikulka
Also still watching the EMU's ( The ISS Shuttle Era Spacesuits ). Kent Rominger indicated that #NASA and #SpaceX are working the valve corrosion issue on Dragon saying this was an issue that has plagued other programs. 5/

Have we heard that before?

So is there a date for the first slc-40 dragon (cargo or crew)? I assume they use the gangplank when they load cargo(late load/perishable) ? Has there been a cargo dragon that didn't use the crew arm(gangplank)?
With ELV best efficiency was the paradigm. The new paradigm is reusable, good enough, and commonality of design.
Same engines. Design once. Same vehicle. Design once. Reusable. Build once.

Basically all of Dragon 1 vehicles. These had late load cargo via a small enclosed space that would pull up to Dragon while in horizontal position. This is similar to how SpaceX will do it for Cygnus as well.

Alex,
How will they get through the Faring without causing a structural issue with a door installed on the faring side?  In the encapsulation photo we received (see below), there is no evidence of a door or hatch to allow access inside the faring as well as walking inside to open the Cygnus door.  Any thoughts?

Where is Jim when you need him...  ;)

IIRC, for other such payloads on other launchers there is a door or access panel in the fairing, but that might require a modified Falcon 9 fairing for Cygnus. Probably not a big deal, but something new.
If we don't continuously lower the cost to access space, how are we ever going to afford to expand humanity out into space?

Yes, Cygnus is using a modified fairing with a 5 foot by 4 foot door, as per last night's teleconference (14 minutes in).

Great.  When SpaceX plucks the faring and the sea water doesn't harm that door (or it's refurbished), it could be re-used for another Cygnus if that comes about.  Thanks, Sam Ho for getting that.

NG has contracted three Flacon-9 flights for Cygnus, so this fairing door is sure to be used at least that many times.
If Antares 330 runs late - I believe that has been known to happen in the space industry ::) - there might be further ride opportunities

I wonder how this is priced. I suspect a customer who wants a custom fairing must pay for the NRE and fabrication. But does the customer decide whether to pay for a expendable or recoverable? Does the customer pay for the recovery attempt? what about a failed recovery?

Think Northrop Grumman pay for the development and additional manufacturing cost for each of the payload fairing half with the access hatch along with the regular build cost. So NG probably own that particular fairing half specific to Cygnus usage.

Speculate NG pay for a recovery attempt as a service plus additional payments for successful recovery and refurbishment.

IIRC each regular Falcon payload fairing half cost about $3M to build. So unless NG wants payout about $4Mi out of pocket for a new fairing half for each SpaceX launch after the first Cygnus , they will pay for the cheaper option of recovery and refurbishment. Maybe they will continue using the recoverable Falcon payload fairing for the Antares 330.

footnote i - speculation

Other people have answered this well, I'll just add that the Falcon users guide does mention this:

p40:
Quote
The standard fairing includes one access door in the cylindrical portion; SpaceX can also provide a fairing with up to
eight access doors as a nonstandard service. The payload fairing doors are all in fixed positions and circular, with a 610-
mm (24-in.) diameter size.

p62:
Quote
Customer access to the payload while the vehicle is outside of the hangar requires special accommodations and is a
nonstandard service.

How did we get from D2 to Cygnus fairing design?

Yeah, but Cargo Dragon 1 didn't use a fairing, right?

No it had nose cone that jettisoned after oribit Insertion. Which was changed to hinged design for D2 made it reusable.

Does anyone know whether the fifth Dragon capsule will be ready soon enough that Crew-9 might get to fly on it, or is it more likely to debut on a shorter flight or Crew-10?

From post FRR conference of Crew 8.

Per Gerst, 5th crew dragon capsule to be ready by Q4 2024. Per Steve Stich, its first mission is likely Crew 10 in 2025.
