- Vance Brand (CAPCOM)
-
Roger. We copy, and could you give us the frame number on that last picture, please?
- Fred Haise (LMP)
-
Okay. We've been writing them all down, Vance, as we went, but that one turned out to be 29.
- Fred Haise (LMP)
-
Okay, Jack says I can't read the camera very well. It should be 28 based on our start frame.
- Vance Brand (CAPCOM)
-
13, Houston. Understand, though, the number showing that you read on the camera was 28. Is that affirm?
- Fred Haise (LMP)
-
Yes. The readability of that thing is like, you know, half a frame one way or the other; so, 28, I think, is a good number.
- Vance Brand (CAPCOM)
-
Fred, did you get any MASTER ALARMS up there about 5 or 10 minutes ago? Folks thought they saw some here and they were curious about it.
- Jack Swigert (CMP)
-
Yes. We were rigging the siren device over the MASTER ALARM, and we were running a test on it.
- Vance Brand (CAPCOM)
-
Okay. Good enough. And anytime you're ready to copy, I've got a pad P37 block data.
- Vance Brand (CAPCOM)
-
Okay. P37 block data, starting with GETI. 025:00, 5119, minus 165, 071:08; 035:00, 7733, minus 165, 070:36; 045:00, 6208, minus 165, 094:52; 060:00, 5993, minus 165, 118:53. Over.
- Jack Swigert (CMP)
-
Okay. 025:00, 5119, minus 165, 071:08; 035:00, 7733, minus 165, 070:36; 045:00, 6208, minus 165, 094:52; 060:00, 5993, minus 165, 118:53.
- Vance Brand (CAPCOM)
-
Stand by 1. We need the LM/CM DELTA-P for one thing, and I'll check back in a minute with the others.
- Jim Lovell (CDR)
-
Okay. And we still have the vent valve open. We'll close it one of the last things and looking at LM/CM DELTA-P right now and I see 0.5 in psi indicated.
- Vance Brand (CAPCOM)
-
Only other readouts we need are those on page 3-13 of the flight plan. BAT C, pyro BAT A, pyro BAT B, RCS A, B, C, and D readings, and DC INDICATOR select main A or B.
- Fred Haise (LMP)
-
And, Vance, we're still charging BAT B. Did you want to dispense with that in a few minutes?
- Jack Swigert (CMP)
-
Okay, BAT C is 37, pyro BAT A is 37, pyro BAT B is 37, RCS A 94 percent, B 95 percent, C 93 percent, D 96 percent.
- Vance Brand (CAPCOM)
-
Okay. In answer to the battery-charging questions, I calculate it should be fully charged at 12:35. Play that one, though, the same as the waste vent. If you want to do it earlier because you're turning in, why that's fine with us.
- Fred Haise (LMP)
-
Okay, we'll continue on with a few other things we got to get done, and just before turning in, we'll check with you, and you can remind us then.
- Jim Lovell (CDR)
-
Okay, Vance. Requesting clearance now to turn the vent valve back to CLOSE again, and also the battery charge off.
- Vance Brand (CAPCOM)
-
We think the spacecraft's looking in good shape. Nobody has any comment down here before you hit the hay.
- Vance Brand (CAPCOM)
-
Just the last comment, Jack. Would you clear Hal, please, so he doesn't burn his lights out there tonight?
- Jack Swigert (CMP)
-
Okay. It'll be just a minute or 2 yet. We have to finish up a couple more chores.
- Joe Kerwin (CAPCOM)
-
Okay. Real fine. At your leisure, you can give us radiation reports, I guess. We are getting a consumables update together for you, and a few other little details whenever you are ready to talk. About the only major thing on the spacecraft is that it's been getting farther away.
- Jim Lovell (CDR)
-
Okay. For information, Fred was on COMM last night; and he was over in the left-hand seat, and if you want our radiation readings, we just goofed. We left them all in the suits which are now nicely tucked away. We are going to get out Jack's suit in an hour or so anyway, and we'll get his dosimeter out if you wanted to get the reading on that one.
- Joe Kerwin (CAPCOM)
-
And in exchange for that, the surgeon would like to have a rough number of hours each of you slept and a qualitative verb to describe whether it was good, fair, or poor.
- Jim Lovell (CDR)
-
We averaged about 5-1/2 hours' sleep apiece, and we are estimating that the sleep was good.
- Joe Kerwin (CAPCOM)
-
Okay. Copy that. Let's see what else we have for you, Jim. Midcourse-2 looks like about 23 feet per second, approximately retrograde and on time. And it's holding real firm now. For your information, and you don't need to copy this down, because it's still pretty soft, but we have an S-IVB impact of about 8.57 south and about 33.9 west, which is a little west and a little south of the flight plan value. We have it at a GET of about 77 plus 51 which is just before AOS, and the LOI pads are a little bit late, and as I say, it's still pretty soft, and we'll be updating you with firm numbers.
- Joe Kerwin (CAPCOM)
-
Okay. And I'll have a consumables update for you in a little while, and I have a small flight plan update for you sometime a little later on when you're ready to copy. There's no big deals in it.
- Joe Kerwin (CAPCOM)
-
And, 13, Houston. We'd like to verify that you cycled the O2 cryo fans. We saw the H2, but we didn't see the O2 get stirred up.
- Jack Swigert (CMP)
-
Yes, Joe. We did, and it kind of looked like we might have had a little stratification because right after we put them on, we had a CRYO PRESS light.
- Joe Kerwin (CAPCOM)
-
Okay, Jack. The flight plan update has a couple of items in it, and the first one we'd like to do is to update the Tephem values in the G&C checklist on page G/9-2. These are fairly small changes, but in case you need them, we'd like you to have the exact numbers. Over.
- Joe Kerwin (CAPCOM)
-
Okay. On that page in line 04, column B, change the number from 03366 to 05253. Over.
- Joe Kerwin (CAPCOM)
-
Okay. That's right. The only other thing I've got for you, Jack, is three additional questions for the booster systems debriefing, which is to take place at about 25 hours, and we thought we'd pass these questions up to you early so you can consider them. Over.
- Joe Kerwin (CAPCOM)
-
Okay. The first extra is, and let me get the original question because this question says, “More specifically on item 2,” and item 2 says, “Were there any significant changes in the noise vibration level during the single stage of powered flight?” Specifically, describe your observations during the early S-II center engine out-off, and approximately 90 seconds prior to TLI cut-off, you reported a high vibration in the S-IVB. We'd like you to describe the buildup of this vibration and its behavior through cut-off. Over.
- Jim Lovell (CDR)
-
Okay. Essentially, what you'd like us to talk about is vibration sequence during the early S-II cut-off of the center engine and also describe the vibrations that we encountered during the S-IVB TLI burn. Is that correct?
- Joe Kerwin (CAPCOM)
-
That's it. Okay. The second extra question is for you, Jim, and it says, “Comparing this flight with your ride on Apollo 8, were there any significant differences in the powered flight environment?”
- Joe Kerwin (CAPCOM)
-
Roger. And the last additional question is what did the ORDEAL ball look like during TLI? As you know, we passed you an update to that setting, and we'd like to know whether it was riding right on zero or what during the burn. Over.
- Joe Kerwin (CAPCOM)
-
Okay. That's it, and that's the whole flight plan update. I have a consumables update now if you want to listen to that.
- Joe Kerwin (CAPCOM)
-
Okay. At 23 hours the total RCS is 1121, quad A is 274, quad Bravo is 286, quad Charlie is 274, quad Delta is 287, and the cryos are as follows: H2 tank 1, 83 percent; H2 tank 2, 86 percent; O2 tank 1, 87 percent; O2 tank 2, 87 percent. Over.
- Jack Swigert (CMP)
-
Okay, Joe. We got all those, and how do we compare them with where we should be in the time line?
- Joe Kerwin (CAPCOM)
-
As I understand it, Jack, you're running slightly ahead of nominal in both those areas.
- Joe Kerwin (CAPCOM)
-
And, 13, Houston. That's all the business I got right now. I have a little news and plan of the day for you, if you feel like listening to that a little later on.
- Jack Swigert (CMP)
-
Okay. Joe. On the news, Jim would like to hold off a little bit on that, and I want to make a request to FAO, if he will at sometime during the day, when we get a flight plan update with those activities we agreed to make optional during lunar orbit and the few activities we were going to delete, I think that I forgot and left that card back during the press of suiting, I left it in the suit room.
- Joe Kerwin (CAPCOM)
-
Okay, Jack. I understand FAO's working on that and we'll have something for you later on.
- Jim Lovell (CDR)
-
For information, Joe, we're all configured back again now to our regular seating positions, if you're monitoring us.
- Joe Kerwin (CAPCOM)
-
Okay. There's not a whole lot to it. Well, let's see, we'll start with the—Let's start with sports, what the heck. The Astros survived 8 to 7, the Braves got five or six runs in the—five runs in the ninth inning, but they just made it; and in the other important game of the day, the Cubs were rained out. I have all the rest of the scores, you can tell me if you want any of them. They had earthquakes in Manila and other areas of the island of Luzon. There were three tremors and they kept the buildings shaking for about a half an hour or so, and it was about a 5 on the Richter scale. Okay, let's see. The Beatles have announced they will no longer perform as a group. The quartet is reported to have made in excess of a half billion dollars during their short musical career. However, rumors that they will use this money to start their own space program are false.
- Joe Kerwin (CAPCOM)
-
(Laughter) Okay. Okay; West German Chancellor Willy Brandt, who witnessed your launch from the Cape yesterday, and President Nixon will complete their round of talks today. Brandt reportedly came to the U.S. to seek assurance from the President to go ahead with talks with the eastern European nations, especially East Germany, Poland, and Russia. Many air traffic controllers are still out, but reports indicate that they are slowly returning to work, and you'll be happy to know the controllers here in the MOCR are still on the job.
- Joe Kerwin (CAPCOM)
-
Okay. Some truck lines are being struck in the Midwest, and the school teachers have walked off the job in Minneapolis. Today's favorite pastime across the—Uh oh; have you guys completed your income tax?
- Jack Swigert (CMP)
-
Yes, Joe. I got to—hey, listen—It ain't too funny; things kind of happened real fast down there, and I do need an extension.
- Jack Swigert (CMP)
-
I may be spending time in a—I may be spending time in another quarantine besides the one that they are planning for me.
- Joe Kerwin (CAPCOM)
-
We'll see what we can do, Jack. We'll get with Recovery and see if we can get the agent out there in the Pacific when you come back. By golly, let's see. In professional basketball, the Nicks beat the Milwaukee Bucks 110 to 102, and Billy Casper is leading the Masters after 54 holes with a 208, and spring football practice is in full swing. And that's about all the news we got; the updated plan of the day for you guys, the uniform will be service dress inflight coverall garments with swords and medals, and tonight's movie shown in the lower equipment bay will be John Wayne, Lou Costello, and Shirley Temple in the “The Flight of Apollo 13.” Over.
- Jim Lovell (CDR)
-
Houston, this is 13. Is it true that Jack's income tax return was going to be used to buy the ascent fuel for the LM?
- Joe Kerwin (CAPCOM)
-
Well, considering that he's a bachelor and hasn't got that deduction to take, yes.
- Joe Kerwin (CAPCOM)
-
Okay, Jack. We'll—We'll take care of it. Tom Stafford says he'll get an extension for you.
- Joe Kerwin (CAPCOM)
-
And Jim McDivitt says, “yes, now that you mention it, he forgot to fill the ascent stage.”
- Joe Kerwin (CAPCOM)
-
Okay, crew. About the only other thing I've got for you right now is an update to your P37 pad for lift-off plus 35. This is a change to the pad we gave you yesterday. The reason for the update is for weather avoidance in the mid-Pacific landing area at 70 hours, which is the return time for this pad, and in case the question arises in your mind, we don't expect any problem there for the end of the mission. The weather area is 20 degrees south of your end-of-mission landing point, and it appears to be moving to the south.
- Joe Kerwin (CAPCOM)
-
Okay. GET of ignition is 035:00, DELTA-VT 7883, Longitude minus 155, and the GET 400K 069:54. Over.
- Jim Lovell (CDR)
-
And, Houston, Jack's going to try donning his suit now for practice, himself, and when he gets it out, we'll give you a dosimeter reading.
- Jim Lovell (CDR)
-
Houston, Apol … Roger. We're thinking together. And we're here waiting for your call.
- Joe Kerwin (CAPCOM)
-
Okay, you were a little broken up there, Jim, but I think it's getting better. We are ready for the launch-vehicle-systems debriefing whenever you are.
- Joe Kerwin (CAPCOM)
-
Roger, Jim. We are ready for the launch-vehicle-systems debriefing whenever you are. Over.
- Jim Lovell (CDR)
-
Okay, Houston; 13. In answer to Question 1, the changes in noise level occurred mainly between the first stage and the other stages—the other stages were about the same in noise level, very quiet, with the first stage, of course, making quite a bit of noise in the beginning but—which built up during the high Q, and then … went quiet just after high Q.
- Jim Lovell (CDR)
-
I might mention that the noise level during the first stage was not sufficient to be uncomfortable at all.
- Jim Lovell (CDR)
-
That's affirm. COMM was very good all during—throughout the entire flight. Much better than I expected.
- Jim Lovell (CDR)
-
Now, in answer to Question 2, there was, of course, a vibration transient in the second stage that—due to the number 5 engine going out—which occurred shortly before the engine went out, and slightly after that then the S-II stage was very smooth.
- Joe Kerwin (CAPCOM)
-
Okay, Jim. I guess the significant point there is that you didn't notice the vibration before you saw the engine light.
- Jim Lovell (CDR)
-
That's right. We—we noticed the vibration but it wasn't such that we thought something catastrophic was going to happen; it just started vibration and then the EN light came on, and then the vibration went away and the stage itself was smooth.
- Jack Swigert (CMP)
-
Yes, and that—it was all pretty—pretty short in span—just a second or so before and like a second afterwards, Joe.
- Jim Lovell (CDR)
-
And on the S-IVB, the vibration of the vehicle itself wasn't what … second … powered flight—a very-high-frequency vibration.
- Jim Lovell (CDR)
-
Well, it was a high-frequency viola—vibration but more noticeable during the TLI burn than it was during the … flight.
- Joe Kerwin (CAPCOM)
-
Okay, I—understand.
Expand selection down Contract selection up - Jack Swigert (CMP)
-
I guess the S-IVB vibration during TLI was there all the time although it seemed to—to grow to us as the burn progressed, although that may have been just due to the boost weight decrease.
- Joe Kerwin (CAPCOM)
-
Okay, you called this about 3-1/2 minutes, but I guess the thing was slowly building up throughout the whole burn. Right?
- Joe Kerwin (CAPCOM)
-
Okay, was it uncomfortable or did it cause your vision to degrade or anything like that?
- Jim Lovell (CDR)
-
No, it—it was not uncomfortable at all but I was recalling the ride on 8, and the S-IVB was more—much more smooth than even it was on 13.
- Jim Lovell (CDR)
-
Okay, now, in answer to number 3, we did not experience any unexpected transients except that all of us noticed the PU shift. We thought it was more pronounced than we had expected it to be.
- Jack Swigert (CMP)
-
Joe, on that. I guess most of every time that PU shift occurred we all—almost all of us glanced at the engine light. We could feel definite acceleration change.
- Jim Lovell (CDR)
-
And, during the high-Q portion of the flight, the Alfa meter, to my knowledge, nearly went above 25 percent.
- Jim Lovell (CDR)
-
In answer to number 4, we got a pretty good look at the thermal shroud and the IU after taking the LM away, and from our viewpoint, the shroud was completely intact. I saw no loose particles or parts of it floating at all.
- Jim Lovell (CDR)
-
And, I guess we answered number 5. I don't think at any time did we have any communication problem during powered flight.
- Jim Lovell (CDR)
-
In answer to number 6, the answer is essentially no. We saw no venting or suspected leak on the LM or the CSM …
- Joe Kerwin (CAPCOM)
-
Okay, Jim. I guess you described to us the non-propulsive venting on the S-IVB after the APS maneuver and we copied that at the time.
- Fred Haise (LMP)
-
Yes, we had already talked about that, Joe. And that was also visible when it—of course, when it did its evasive maneuver when we were looking at it right close up.
- Jim Lovell (CDR)
-
Okay, Joe. The last time we saw the S-IVB positively was when Fred saw it venting at about—at about 5 hours. We think we might have picked it up later on. We saw a particle or something out there that was tumbling which might have been the booster or one of the SLA panels.
