I noticed that in the recent pictures of the interior, there where just four seats in the Dragon 2 Trainers. I do remember earlier pictures showing up to three additional seats. Were those nixed? When this was done? Or is it that there is a planned flexibility to make the interior with more seats in case needed?

Four seats has always been the base configuration for NASA flights.
Wasn't there talk of something to enable a single Dragon to evacuate a 7 person crew?

They would have to remove the cargo areas and the toilet, and then install 3 more seats in order to do that.

What toilet?

Three pics from media event today: CD upper hatch, training cabin interior from Hawthorne (to me more realistic then the unit in JSC) and interior design sketches.

I mentioned it in the previous thread.

Toilet standard on the 2.6B version, not available on the 4.2.B version?

Posted on August 13, 2018

SpaceX has given the press access to its Crew Dragon simulator and custom-built spacesuit for the first time, providing an extraordinary level of detail and even the freedom to take photos of almost every aspect of both items.

pospa's and teslarati's photos seem to be from a different capsule. The exterior is different (yellowed and not smooth) and you can see the side door support cylinders (JSC capsule has no side door). The seat design is also slightly different, it has more prominent side support near the top. Not sure which one is more up to date though.

The pictures I've seen from NSF reporter were of the same mockup that was on display at JSC. Maybe there were two different capsules and that's why there are pictures of a different one?

I don't believe they have to remove cargo area and toilet. It is a NASA requirement that they have 7 seats available for emergency evacuation. I assume this means that 3 spare seats will be stored on the ISS. This requirement applies to both the Dragon and Starliner.

What handles and hand-rails? They aren't needed. People in 1G can get in-and-out just fine with what you see in the photos. And you don't need handles in zero-G. The cabin is so small that a wall, ceiling, floor or seat is always within arms-reach of an astronaut.

I suggest you review on-board ISS footage. Notice the hand-rails in the modules? Now notice how often they are used by crew.

They mostly aren't.

The crew moves around by ever so slightly pushing off from (with feet and hands) whatever surface they have under reach.

Discussions of the ISS module interiors is rather off-topic but since you brought it up so authoritatively and since I was there in the design trenches at the time (and from the tenor and content of your post, you clearly were not), let me explain why those zero-g mobility and restraint aids are there in the ISS: they are there because NASA-STD-3000 required them to be based on prior shuttle and Skylab experience. Further, they are not just there for day to day moving around the element interiors. They are there for tilting racks out and performing repairs or maintenance. They are there for moving racks in and out of rack spaces (which is a thing that was done during shuttle support flights and was expected to be a routine operation for the life of the station). They are there for contingency ops like a fire, a major depressurization event or attitude excursion.

Now how much or how little any of that has to do with Dragon 2 is open for debate, but the reason why such provisions exist inside ISS modules is not.

You made the mistake of assuming that I assumed that those hand rails are there for crew mobility ONLY.

I'm well aware of their true purposes. Aiding in crew mobility is only one of many functions, as you so accurately described.

Unconventional thinking ($2.6B) versus conventional thinking ($4.2B). Why do you think the Crew Dragon pressure suit looks cool whereas the Starliner suit does not less so.

The one with the more prominent side support at the top (the HQ simulator) is the up-to-date one.

Correct, the HQ simulator is more up to date than the JSC one. Still no hand-rails, camera holders and seat-mounted flight controls though (sorry, couldn't resist the dig  ;)  )

This will be the first Crew Dragon to carry astronauts. It also now seems likely to be the first American spacecraft to carry astronauts to orbit since the flawed but venerable Space Shuttle. Amazing. @NASASpaceflight #SpaceX

The tilt of the seats is interesting. Much more upright than the flat-on-the-back position of the Shuttle or Starliner. Can the tilt be altered? And does the control panel hinge down to a position convenient for the crew in the middle seats?
