Spacelog Apollo 13

Houston, 13.

Go ahead, Jack.

Okay. We're still in good shape as far as water goes in the LM?

Okay. We copy.

The reason I ask is I'm assuming that we are, and I have no idea each time I pressurize the surge tank to get water out of the command module, how much I drop that surge tank and if we are in good shape as far as water goes in the LM, we'd like to fill a couple of drink bags to get some water for drinking purposes.

Okay. Have you run out of CM drinking water. yet, Jack?

Oh, no, we've got plenty of drinking water. I think the—I don't have any idea what the surge tank pressure is.

Okay. It's 750 —

— and I don't have any —

It's 750, Jack.

Okay. 750.

Aquarius, Houston.

Go ahead, Vance.

Okay. Stand by 1, Jack, and we'll give you an indication of how that water situation on the LM is—which is your question. Right?

Okay. But I guess what I was really asking is, if you'd have any violent objections if we filled two drink bags from LM water rather than repressurizing the surge tank.

Okay. Stand by on that.

Also, Jim is asleep up there and we didn't want to bother him, either.

Okay. We understand.

And, Jack, we'll be changing stations in 1 minute; so, we may have a temporary dropout in COMM.

Aquarius, Houston.

Okay, Vance. Go ahead. Loud and clear.

Okay, Jack. We're going to bargain with you on this one. Instead of two, would—wish that you would just get just one bag full. That shouldn't do any harm; however —

Okay.

— we are not all that fat on water that we want to do any drinking out of the LM as a regular thing after this one bag. So would you let us know when you get the water out and give us a mark on it so we can watch the TM. Over.

Okay, Vance. We've withdrawn—oh, about 8 ounces of water.

Okay, Jack. How's it taste?

Apollo 13, Houston—or rather, Aquarius, Houston. Over.

Go ahead.

Hey, Jack, we need another reading. Volts and amps.

Vance, you won't believe this, but Fred-o says it's 39.4 and 1.245.

Okay. Our EECOM is recording those numbers. Charlie Dumas, this time.

Oh.

Not changing very fast, is it?

How far out are we?

Okay. 953 and 6068 on velocity, per FIDO.

Okay.

Bill Stoval.

Houston, Aquarius. Over

Go ahead, Aquarius.

Are the flowers in bloom in Houston?

No, not yet. Still must be winter.

Suspicions confirmed.

Yes, I doubt if they will be blooming even Saturday, when you return.

I concur.

Hey, Jim, we have some photo information to pass up to you. Discussed this briefly with Fred earlier. It's instructions or suggestions for which photos—which cameras and lenses to use during your service module photography. Over.

Okay. Stand by 1.

Okay.

Go ahead.

Okay. We have three cameras here, two of them to be used for picture taking from the LM, one to be used from the number 5 window of the CSM. First, I'll hit the LM cameras. And this camera that I mention now has first priority. It's considered the one to give you the best results. That's the 70-millimeter DC Reseau camera, Hasselblad, that is, with the 80-millimeter lens, from box A-13. Suggest fresh magazine of 3400 black-and-white film.

Okay.

Okay. Suggest either magazine R or magazine S from A-13. Transfer all of this to the LM and recommend the following settings: LM/DC/80/BW 3400 (f:5.6 at a 250th).

And that's all for that one.

Okay, Vance. Let me see if I have it here. For the LM, want to use the 70-millimeter DC Hasselblad 80-millimeter lens in A-13, using 3400 black-and-white film MAGs R or S. Prepare to take camera to the LM, and the setting would be the LM/DC/80/BW 3400 (f:5.6) at a 250th.

Okay, Vance. Essentially, what you wanted to use as far as the movie camera in the LM goes, is our lunar sequence camera which is attached to the powerpack. We use the 18-millimeter lens, set it at 12 frames per second … f:8 at 250th of a second.

Roger. f:8 at 250th.

Right; f:8 at 250th.

Okay. Would you believe that we have a correction now to the last camera I gave you? Correct that 18-millimeter lens to 75-millimeter lens.

Okay. The 18-millimeter to the 75-millimeter lens. Okay.

Right. Okay. Next for the command module pictures, it may be a little hard to see the service module from the command module, but if you can see it, it will be through window 5, people down here think. Recommend for that the CM 70-millimeter. These photos have priority 2. So this is 70-millimeter EL, with—which has the 80-millimeter attached, and this is all in B-3. Take off the 80-millimeter lens and attach the 250-millimeter lens. And the 250-millimeter lens can be found in U-4. Use CEX film from A-13. Ring sight from A-7, and these pictures will be f:8 at a 250th. And I think probably by now you probably all have—already have these cameras configured, and this may be redundant information, but here it is anyway. Over.

Okay, Vance. You're right. We do have cameras almost configured like you said. For the command module, you think that the EL with the 250 lens, CEX film, f:8 at a 250th is the best bet, and you're saying now that where you think you'll see it is out window 5? Is that it?

That's right, Jim.

Okay. My procedure, now, after service module JETT is going to be to pitch up, in order to try to get the service module into the—to get the center window in view of the service module, which we are going to have somebody there—to photograph. Why do you think window 5 will be it?

Aquarius, Houston. Over.

Go ahead, Houston.

Jim, regarding window 5, I have a drawing here; and, when you're docked, you have approximately a 60-degree angle between the Z-axes of the two spacecraft. It appears that peering out window 5, you would be looking at the rendezvous radar on top of the LM which would, if you pitched, more or less give you a view of the service module. That is, if you pitched, so—from—and I think that this has been run by quite a few folks here; so, offhand, I can't see where any other window would be as good or perhaps even possible.

Okay. I understand. Yes, you're right. When we look out window 5, we can see rendezvous radar, and we'll try—We'll try window 5.

Roger. It presumes, though, that there has to be a pitch to be able to see it. You guys sound a lot more rested today.

Well, I just went back and sacked out for an hour or so and didn't get back up.

Very good.

And, Jim, Houston. We really are going to get those checklists up to you.

Aquarius, Houston. Over.

Aquarius, Houston. Over.

Go ahead, Houston.

Jim, it's time for readings on the battery charging again. Request the BAT A voltage and the charger amps. Over.

Houston, Aquarius.

Go ahead, Jim.

Okay. We have no more water in the potable tank. We tried to get some more out a few minutes ago, and there isn't any.

Okay. Understand you ran out of water in the CM potable tank.

Aquarius, Houston. Over.

Aquarius, Houston. Over.
