Spacelog Apollo 8

Right.

Okay. And the step shows the tape recorder to REWIND at minus 30. Now that's an onboard step rather than a ground step, just to verify that.

Okay.

Okay. Under step 6, almost at the bottom—in fact, it's three lines from the bottom of step 6—there's a section that says secondary coolant loop evaporator to RESET, and should be a note that that's 58 seconds if you hold it in RESET prior to moving the pump OFF.

That's it; that's in it.

Okay. Okay. The next comment is on page E-13.

Okay. I'm there.

Alright. This is a general comment that refers to any time you're working around P62 or when you're going between P62 and P63, and you should be careful not to call an extended VERB during this time. This is here in the program notes, and it is just a reminder. What will happen if we get into an extended VERB such as an 83 or an 82? We may get hung-up in P62 and have to recycle through it in order to get the 63, and neither of these displays are normally used, and it's just a good practice. And we're just trying to remind you that we don't want to call an extended VERB while we're in P62.

Okay. Neither do we. That's right.

Okay.

Okay. In going through the rest of it, we didn't find any other things to make comments on. You have all the latest corrections in your checklist.

Roger. The main thing, that is to come up with a way to determine that the boiler—water boiler is not dry and make sure that Bill gets it activated at TMS 7.

That is correct, and we will talk to you some more about that next time we catch both you and Bill up.

Ken, this is Frank. I am going to be off the headset for about 5 minutes here.

Okay. Fine. When you come back, I will have a systems rundown for you.

Houston, Apollo 8.

Okay. Loud and clear.

Back with you.

Okay. I've got a few good words for you. The erasable memory has been taken completely apart and looked at, and it looks like it's all okay. Your P01 didn't have any effect. The one thing that might be questionable is if you used a VERB 67 when you get to the NOUN 99 display, you may find that one to be unreliable, and what you're going to get there is the—that's an error display for the W-matrix. And it's something you probably won't be using again anyhow; and if the occasion arises, we can update that one, but it's not a normally used display and everything else, all the operational functions, are good.

Very good.

Okay. As of 114 hours, your batteries—you had battery A with 39.32 amp-hours, battery B had 35.21, and battery C 38.46. Your cryo quantities remaining at SEP were the same we gave you the last time, 180 pounds of oxygen per tank and 11 pounds of hydrogen per tank. At present, the service module RCS, using the computer values for the quantities, you have quad A with 45 percent, Bravo with 50, Charlie with 58, and Delta at 48. What we plan to do with the secondary tanks is to go ahead and turn them on at 37 percent actual, and in the event of lost COMM or something like that, recommend that you use 50 percent onboard gaging as being the time to turn the secondary propellants on. However, as long as we can use our own calculations, why, we might as well leave them tied up. We probably won't get into the secondary propellants prior to entry anyhow.

Roger.

Okay. A couple of items I want to check up on: I'd like to confirm that the hatch Dog will be taken off while you're on the chutes if you can. If not, you're going to do that in the water. Is that affirm?

…

Okay. Now we've got a little better signal. Like to confirm that the hatch clamps on the side hatch will be taken off either on the chutes or in the water, whichever you can get to. Is that affirm?

Roger. That's affirm. As a matter of fact, we didn't even put—didn't even put them on.

Okay. Do you plan to put them on for an entry?

I don't think so. It's held pretty well so far. I don't think—everybody tells me it wouldn't help much anyway.
