 We're going to talk about the 70 millimeter camera system. The other day we talked about the 35 and we talked about how that is primarily designed for in-cabin flash photography. Occasionally we'll shoot things out the windows or EVA with the 35, but the 70 is designed primarily for taking photographs out the windows. And it's a wonderful camera system. We're going to talk about the displays and controls first. And then we'll talk about its operation. And then we'll talk about the spot meter, which is the way that we determine exposures. Because this is a purely manual camera. There's nothing automatic about it except for the fact that it has the motor drive in advance of the film automatically. Let's start with the displays and controls on the very front of the camera. The button right here is the shutter I'm sorry, the lens release button. And this has to be depressed in order to remove the lens. When we're putting a lens back on though, we want to make sure that we don't depress this button. We want to be able to hear and feel the click to make sure that the lens is installed all the way. The shutter release push button is right here. It's an oversized button. This was a NASA suggestion so that when the guys were wearing gloves, if this would be used outdoors, then their large size glove finger would depress the button. On the right side of the camera body is the mode selector switch. If it's not in that position, then the camera has not finished a full cycle. And you would refer to the malfunction procedures. It means that either the batteries have died, or there is a jam in the magazine that's not allowing the film to advance in their force jamming and not letting the camera finish a full cycle. Turn the module on when you first install the magazine. Don't turn it off until after the whole thing has been shot. Of course, if you have a problem with the mag, you're going to take it off and certainly you turn off the data module and you note that this is a bad magazine. If you have a problem where you do get a red light for some reason, go ahead and take this module off and take a module off of another magazine that you've already exposed and trade out modules. Even though the frame number and magazine number won't be wrong, the GMT will still be correct. Should you turn that off? You should leave it on when you transfer the magazine on. That won't make any difference. You can transfer it. You can turn it off anytime. But our concern is that if you turn it off, you may forget to turn it back on. You can bring it up. I recommend using the latch back here in the bag rather than putting additional wear and tear on the camera by forcing it up here like that. And I'll wiggle it and make sure that it's on. This way, it just seems a little more kinder. And then when you're ready to shoot, you'll make sure that you pull the dark slide. Now you cannot get the magazine off because the dark slide is not installed. The dark slide gets into this very narrow slit. You can install the dark slide either way. We'll just start here on the mid-deck. Pretty much everything's the same in terms of the airlock and the lockers and the floor compartments. Right now there's a Maher mid-deck accommodations rack where the galley is normally. And this is still under development. There's not going to be one under flight with another galley there. The hatch over there, MS3 no longer sits by the side hatch. There's a couple things that are different up on the flight deck that we'll look at when we get up there. Different than still much? No. The locker trays and all that kind of thing works the same way. The floor compartments are all the same. The only thing that's going to change is where your seats and treadmills are attached. We don't have as much volume over here to use as it looks like because the sleep station is running out. Stowage is still going to be cramped in terms of storage space for a 7-man crew for a week. It's going to be tight. And you've got suits now. And so that makes it even worse. Although it looks like we might have a trash compactor. No kidding. And there's a new, we'll see this tomorrow, but there's a new type of beverage container. It goes along with that trash compactor that old ones wouldn't compact. The square ones will still be on board but they're starting to fly a mix of these new ones and the new ones are compactable. We'll talk about the flight data file now and we're going to start off with the mid-deck stuff which is beginning up. Now I need to add a sheet to this that you'll need procedure procedure-wise. But there's also a few little extras that are considered flight data file are managed by the flight data file people and they're considered the flight data file. And that's things like the pens and writing instruments and book clamps the tethers that will restrain books in place. Those things are all considered part of the flight data file. Now this is something you'll probably recognize. It's a little orbit map and they still fly this although it's losing its utility because of the spot that shows you a display that includes this and a lot more. So this is still on the inventory though. There's a mid-deck new cards kit. Now your first page of your handout gives you a list of what kinds of things are typically found in the mid-deck flight data file. The mid-deck new cards, these are things for the mid-deck systems like you'd expect. There's a tags card there's several cards for medical DSOs that you can pass. Do one of those, there you go. Sam will do all those. Yeah, these are pretty much just referencing as you need to and stick it where you need to. Yeah, the flight data file accessories bag and it's not full because there would be a bunch of marking pins in here too but these are book clamps. There's a couple different sizes of book clamps to hold the book open to a certain page and you can stick it to the block or base. Those are new, yeah. That allows for larger books. I think they have some of these at Marshall now. That looks much better. I think this works fine. You can even do it with two pages. Hold two pages open. That will work in zero change or more items in the locker here. Of course, your payload checklist. I've got it loaded with a bunch of IUS checklists now and you're familiar with your own payload checklists. There are a couple of photo TV checklists which I'm sure you'll be using for a set of photo TV scenes to beam down and there's also camera information here on the manual cameras and camera malfunctions. Things like that. We still have those for the overhead and aft windows but the forward windows are cloth covers that are rolled up in those containers and you just unroll them and stick them to the window with Velcro. There's nothing to put in the window shade. The EMI and shields and the aft shades and filters and those things are all still the same and that bag is still down there. It's just in there. Roll it out and then it sticks to the window frame with Velcro and they're very nice. The two forward windows 3 and 4 are hard to operate just because the hood's in the way.
