CMP: Okay, Vance, I'm ready to continue. I'm ready. Go ahead.
CC: Okay, new subject. Like to break in to say that request you're-initialize the PTT - PTC. For some reason, it's gone up to 18 degrees in pitch and yaw both. We don't quite understand this. All we can think of is - start it again. Over.
CMP: Okay. We'11 go back. Tapo 22/0
CC: Okay. We are at the - the end of the changes in the solo book, and I have two pages of changes in the flight plan. Those are pages 3-122 and 3-125. While you're looking that up, we'11 put Ken on to answer your question.
CMP: Okay. I'11 start back - let me start back re-initializing PTC here.
CDR: Okay, Vance, I'm on 3-122 of the flight plan.
CC: Okay. Okay, about - at time 156:50 on the right - well, on the right-hand half of the page, there's a line which states "Visual target 16, south, 180 plus l:11, Gassendi, f:lS." Request you cross out that line.
CDR: Okay, we'11 cross them out.
CC: That's all on 3-122. Next change is 3-125.
CDR: Okay, I'm looking at 125.
CC: Okay, starting from the top of the page, cross out the first five lines, which are "Set up camera for contamination and photography, CM4/EL/80," Betelgeuse, et cetera, "MAG T," et cetera, "Install window shades."
CDR: I've got them crossed.
CC: Okay, then jump down to just about 159:28. Cross out "Maneuver to contamination field photography attitude," and all other lines below that through "Enable thrusters A3, C4, B3," et cetera.
CDR: Okay, so we start with "Maneuver to contamina- tion field photography," and we cross out every- thing down to and including "Enable thrusters A3, C4, B3, and D4."
CC: That's correct. And those are all of the flight changes - flight plan changes we have. And Ken is coming on now and later sometime when we get PTC squared away, and it's convenient, I suppose you should read all these things back to make sure that wetre squared away on them. 22/10 Tape Page ll0
CMP: Okay. Go ahead, TK.
CC: Yes, sir. Understand you have a question.
CMP: Yes. I guess I didn't understand what the letter and the number was behind some of these photo targets.
CMP: Does that refer to the pages?
CC: Yes, sir. That's the map. Each fold is lettered in the lower - or upper right-hand corner if you work your way from east to west and the charts are labeled D, E, and F and the solo stuff will all be the D and E, and they change with the plane change 1. That's the time they change the two maps.
CMP: Okay. I got it. Thank you.
CC: Yes, sir. You're doing good work, hey.
CMP: Well, I had a good prime crewman that taught me all I know.
CC: Don't run out.
CMP: Hey, when FIDO gets a good hack on our trajectory, will you let us know?
CC: How long you willing to wait?
CC: He's looking at his calendar, if that means any- thing.
CMP: (Laughter) All right.
CMP: Okay. I'm back at the attitude here, and I'11 wait for rates to damps and you let me know when we're stable again.
CMP: Go ahead, Vance. Page lll
CC: Roger. Just a reminder you have to disable Charlie and Delta here as you've done in the past. Over.
CMP: Okay. I was kind of holding off on this. We're dumping a little waste water now.
CC: Okay. FIDO says he knew it all along. He's - he says he's been very concerned that you've been doing a lot of water dumping.
CMP: Okay, Vance. We've got quad C and B disabled.
CC: Okay. Copy, Jack.
CC: It may be awhile before your rates are settled down. We're still observing fairly high rates and deadbanding. Over.
CC: Okay. We've got about three items. First one is, all of your P23 batch - two marks have been evaluated and - Hey, congratulations. Looks real good; they're very happy with it. You're down to 4 arc-minutes on the substellar-point aspect of it, and that's the first thing to mention. The second is, unless you see a need, I don't see any need for you to read back the information we gave you on the solo book and so forth. Do you concur?
CMP: Roger. I think I got it. I remembered a lot of it, and so I think with what you gave me and what I remember, I'm pretty sure we got it right.
CC: Okay, and the third item, I was Just about to call that your rates were stabilized to start the PTC, but it looks like they're Jiggling around again from a dump, so we'11 stand by some more.
LMP: No secrets around here.
CC: Say again. Hey, that's right.
LMP: I said there's no secrets around here.
CC: Yes. Big Brother is watching.
CC: lB - -
CMP: I can Just see EECOM telling FIDO.
CC: Yes. You really have to watch that pair, all right. By the way, we have a maneuver pad for you, a fly-by pad, whenever you're ready to copy.
CC: Okay, maneuver pad, purpose: fly-by, SPS/G&N; 63385; plus 0.97, minus 0.23; 072:24:33.08; plus 0212.7, minus 0141.7, minus 0254.8; 148, 316, 050; NA, plus 0022.5; 0360.9, 0:53, 0356.3; 33, 352.7, 15.0; NA, NA, NA.

CC: Roger. That's correct. Want to verify under NOUN 81 that DELTA-V X is plus 02127. You cut out right there.
CDR: Roger. DELTA-V X is 02127. ']'ape22/ 13 ]"age 113
CC: Roger. And your ratea are low. Looks like you can start the PTC.
CMP: Okay. In work.
CC: Okay. And when the computer is available, request POO and ACCEPT and we'11 ship you your state vector.
CDR: Wait until I get PTC going first, Vance, then wetll give it to you.
CMP: Okay, Vance. We're POO and ACCEPT. The computer' s yours.
CC: Roger. Here it comes.
CMP: You know, somehow, everytime I do a set of P23s, you guys uplink me a state vector. I don't think I do too well.
CC: No - -
CMP: I could get a complex.
CC: No. You know - you know how the FIDOs are. They like to load in their own data, no matter what.
CMP: But our state vectors take into account the waste water dumps.
CC: Yes, that's -
CC: Apollo 13, Houston. It's your computer again.
CC: And as a matter of interest, understand that the downrange comparison between the MCC and the computer is within 35000 feet, and that's on the last sighting, which people think is pretty good.
CMP: Okay. Maybe that gives us a little more confi- dence that if we had to do P23s on the way home, we'd make it.
CC: No doubt about it. 23/1 Tape
CC: Just info on your PTC, Jim. It's looking very good. Just - excursions in pitch and yaw are very low.
CDR: Okay, thank you. And we're going to change another lithium hydroxide canister now.
CMP: And, Vance. Has FIDO come up with any obser- vations on the trajectory?
CC: Well, a minute ago, he said that to tell you that he was pacified now after your past comments on his trajectory and so forth, and he hadn't seen any waste water dumps or anything and he's pretty happy.
CMP: Okay. I just wondered if we're going to need any more mideourse.
CC: He says, seriously, it's looking probably like you won't have any more.
CMP: Hey, that's real fine.
CC: FIDOs never guarantee anything, however.
CMP: Yes. That's right.
CMP: Houston, 13. I have the onboard read-out, if you're ready to copy.
CMP: Okay. BAT C 37, PYRO BAT A 37, PYRO BAT B 37, RCS A 97 percent, B 97 percent, C 96 percent, D 97 percent.
CC: Roger. We copy that. Thank you.
CDR: Go ahead, Vance. Page Ii5
CC: Jim, Just an item for you _md Fred to be thinking about in case you haven't been briefed on this, something that's now being talked about a little bit. These conservative people would like to have you read the SHe tank pressure when you go into the LM for the LM familiarization at 58 hours. If there's no midcourse-3, and it looks like there's a good chance that there will not be, why, they might want to move the LM familiarization up from 58 to 55 hours. Over.
CDR: Okay. If we don't have a midcourse-3, then we'11 probably move LM FAM up to 55 hours, in which case we'11 go in there and read SHe tank pressure.
CC: Roger. Along with the other FAM stuff, and it's not certain that we want to do this, it's just being talked about, so this is Just the informa- tion for you.
CDR: Okay. This is beginning to sound like the SIM that we ran not too long ago.
CC: I don't think it will be a very big deal.
CMP: Okay, Vance. Our LM/CM DELTA-P is 0.9.
CC: Roger. 0.9.
CC: Are you guys hacking into your presleep checklist yet ?
LMP: Oh, we Just finished eating and cleaning up a bit afterwards. Jim's going around collecting debris off of all the inlet hoses. And, I guess you might say we're kind of thinking about getting ready to go to sleep.
CC: Well, I hope you had a good meal.
LMP: It wasn't too bad.
CDR: (Music)
CC: Sounds like you guys are really living it up up there. All that music, food. I didn't say drink.
LMP: Yes, it is pretty nice. Not bad at all. You're right; you didn't say it. This PTC we're in is a pretty - pretty nice merry-go-round, Vance. Every 10 minutes alternately I get to look at the Earth and the Moon.
CC: You couldn't ask for anything more than that. Just so it isn't so fast you - -
LMP: No, it's a lot - a lot better. I remember from 8 when they didn't hardly ever get to look at either one.
CC: That's right. They were tumbling about another axis, weren't they.
LMP: It's pretty cloudy down there tonight. About the only land I can see again is a portion of Australia and Korea and looks like a part of China. Just about clouds covering everything else.
CC: Can you still see that clearly with the naked eye, or do you have to look through a glass?
LMP: I can see Australia with the naked eye and the China landmass, but I - It took the monocular to pull out the Korean Peninsula.
CC: How about the Moon? Is it looking very big yet?
CC: No, not really. Bigger, but we've got a ways to go.
CC: I understand that they're estimating your pericynthion - lunar pericynthion is now 62 miles.
LMP: Well, that's not bad.
CC: That's supposed to be Just right.
CC: Go ahead, Jack.
CMP: Okay. We're into the presleep checklist now. As far as the crew status report, as far as medication goes, we've had no medication. And we're all feeling really good. I've given you the onboard readouts. Jim is chlorinating the potable water now. I'm ready for an E-memory dump whenever you're ready.
CC: Stand by 1 on the E-memory dump, Jack. I think we'11 be ready in about a minute.
CC: And EECOMM says that as soon as you stir your cryos, request you go back to AUTO on that one tank.
CMP: Okay. We'11 do that.
CC: Hello, 13; Houston. We're ready to take your E-memory dump.
CMP: Okay. Coming down.
CC: Apollo 13, Houston. Were you trying to call?
CC: Apollo 13, Houston. We thought you were trying to call. Were you?
CDR: I don't believe so unless we inadvertently hit the microphone button.
LMP: Must have been some other guy trying to call, Jack.
CDR: Just trying to get some words in, eh Jack?
CC: Roger. We saw the downvoice subperiod come on. We thought maybe you were trying to call. Sorry. I hope we haven't disturbed you and from where I sit, it looks like you're running a rest home up there. Good night.
CDR: We're all going to bed now Just after we play the last rendition of "With Our Eyes on the Stars."
CC: Okay, Jim. And we'd like you to check your S-BAND NORMAL voice switch, OFF.
CDR: S-BAND NORM3kL, OFF.
CDR: Houston, 13. We'11 he off COMM; so if you need us, send a crew alert, please.
CC: Okay, Jim. If we need you, we'11 send a crew alert, and we'd like to know who's got the duty tonight on the BIOMED. Is that you?
CDR: Yes. I'11 he on the BIOMED.
CC: Okay. We copy, and you're spoiling my good record of two watches without saying anything.
CDR: Just want to keep you busy, Jack.
CC: You're waking me up. Tapes 25-29/1 REST PERIOD - NO COMMUNICATIONS 30/I Tape
CDR: Houston, Houston, Apollo 13. Over.
CC: Good morning, 13. You're early.
CDR: Ah so. I Just thought I'd be waking up. And we are awake and getting the spacecraft shipshape. eee
CC: Roger. Spacecraft is in real good shape as far as we're concerned, Jim. We're bored to tears down here. We do have a few little items for you, like a P37 update and a couple of flight plan updates. But there's no rush about them. Over.
CDR: Okay. Gig us again in a few minutes. We're breaking out some food, and we'11 copy them then.
CC: Okay. And the surgeon will be ready for your sleep report whenever you get that together.
CDR: Righto. If he's listening, LMP had a solid 9 hours of sleep; I couldn't wake him up this morning. The CMP had 6 hours, and the commander about 5 intermittent.
CDR: Jack's dosimeter - Jack's dosimeter is reading 02026.
CDR: It might be interesting that just after we went to sleep last night we had a MASTER ALARM and it really scared us. And we were all over the cockpit like a wet noodle.
CC: (Laughter) Sorry it wasn't something more signif- icant. I've also got a procedure for you on that H 2 tank; simple thing after you get done stirring up the cryos.
CDR: (Music - With Their Eyes on the Stars)
CC: That was beautiful. What was it?
CDR: A little of "With Their Eyes on the Stars" to wake up to.
CC: Sounds like all the comforts of home. Have you guys got a flower on your breakfast table?
CDR: Yes. Jack! Tape =hi/ 1. Page ]P2
UNKNOWN: Iloust, on, Apollo 13. Over.
UNKNOWN: I _, Ih)m;t, cm. (h, a,h¢'ad.
CC: ]3, this is Houston. Go.
CDR: Roger, 0oe. Wo're standing by for that P37 block data ii'you have it for us.
CC: Okay. Got it right here, Jim, and it follows. This is the P37 pad for lift-off plus 60. The reason for the update is for weather avoidance in the MPL at 119 hours. It's the same one we passed you yesterday, and it's the same weather, but we still don't expect a problem at the end of the mission. GETI is 060:00, DELTA-V T 6079, longitude minus 153, GET 400K 118:04. Over.
CDR: GETI of 060:00, 6079, minus 153, 118:04.
CC: Roger. That's correct. I've got a consumables update for you, Jim, if you're ready for that.
CC: Okay. As of 47 hours, RCS total[ 1096, quad Alfa 270, Bravo 278, Char]ie 270, Delta 278, and the H2 - - They gave me the H2s in percent, 76 per- cent; and on the 02 we have 81 percent. However, we show the 02 tank 2 reading off-scale high now. We're quite sure it's a sensor failture. We'd like you to verify it with your onboard reading.
CDR: Joe, we confirm. Our gage reading is - on the number 2 02 tank is reading off-scale high now, but Jack just tells me that it was okay when we first looked at it this morning.
CC: We verify that. At 46:115 we had 82 percent and · apparently when he stirred the, the cryos, the sensor broke.
CC: So it's no problem. You're above nominal on all your consumables. On the H2 tank problem, we have a procedure that we'd like you to carry out which is simply turning the H2 tank 2 heaters to OFF at this time s and we want to see whether that won't solve the problem of the tank pressure setting off caution and warning. We want te look at it that way for a few hours.
CDR: Okay. You want both H 2 tank 2 heaters to OFF. Is that correct?
CC: That's negative; just tank 2. We want tank ± to stay in AUTO.
CDR: Okay. Tank 2 heaters off at this time.
CC: Okay. Good deal. That's been the high tank and apparently while waiting for that pressure switch to close, to start the heater cycle, the tank i pressure has been dropping even a little bit lower and just setting off caution and warning, so we feel if we turn off the tank 2 heater and let tank 1 activate the heater cycle, we won't get into the ca_tion and warning range.
CC: Oke_, Jim. At your convenience we'd like POO and ACCEPT. We're ready for - to upl_nk your state vector now since we will not do midcourse 3. Over.
CDR: Roger. You're in POO and ACCEPT, no midcourse 3, and we're all set for a state vector update and I'm giving you the LM/CM DELTA-P here shortly.
CC: Okay. Good deal. And I have flight plan updates for you later, at your convenience.
CDR: Houston, Apollo 13. The LM/CM DELTA-P is 1.0 psi.
CC: Copy, 1.0, Jim.
CDR: Houston, Apollo 13. I'm about ready for any flight plan updates that you have.
CC: Okay, 13. To start off with, got a minor pro- cedural change for Jack on his next P52, if he's ready to listen to th_:.
CDR: Okay. Jack's still off COMM. We'11 hold off on th:d, ,ct iittle bit and thou we'11 pick it, up when 1)_' gct.s on COMM,
CC: Okay; 1'[nc. I've got two updates f'oryou, ,/:im. One is a procedure for looking for Comet Bennett at about 49:45, and I'11 wait till Jack gets up before passing you the details on that. The other update is concerned with going into the LM 3 hours early, and I think Vance mentioned to you last night that this was a possibility, that we'd like to look at the SHe tank pressure early. And since we're not going to do midcourse 3, we'd like LM entry at 55 hours. Is that okay with you?
CDR: Okay. Right, that's fine with us. We'11 move up LM entry to 55 hours.
CC: Okay. I've got some details on the flight plan for you as follows. Of course, since there's no MCC-3 you'11 be deleting all the midcourse 3 stuff including the - the P52, which is called out at about 54-1/2, and we'11 be slipping that until later, which I'11 - which I'11 tell - which I'11 tell - which I'11 tell you in a minute. Okay. Then you - we want to move the battery charge up 3 hours to about 52:30. And we want to move the - moving the LM tunnel vent valve to LM/CM DELTA-P up B hours to 52:45, and at that point you can simply go to the 57-hour point in the flight plan and change your number from 57 hours to 54 hours and start through that. In the remarks section at about 57:50 it says, "0 fuel cell purge and waste water d_np," here. 2 If not performed earlier, we want you to do that at 54 hours and 50 minutes. The TV pass then, will be at 55 hours to 55:30. You'11 go right through the LM Activation checklist stuff. I'm losing you; let's wait a minute.
CC: 13, Houston. How do you read me?
CC: 13, Houston. You back with us?
CC: Apollo 13, Houston. Are you back with us?
CDR: We're back with you.
CC: Okay. I've gone through the battery charge, the LM vent valve, the fuel cell purge, and then stop PTC at 55 hours, and your roll attitude there will be 285 degrees, which is per the flight plan. The high gain antenna angles are slightly different, pitch 23 and yaw 267 degrees. The TV pass till 55:30, the standard LM acti- vation except for some special steps we'11 give you to take a look at SHe tank pressure, which I don't have yet. Restart PTC at about 56:30 or whenever you're through with the _4 activ- ities, and after that, at your convenience, we'd like you to - to do the P52 option 3 that we cancelled at 54-1/2 hours. Over.
CDR: Okay. That last comment was that we'11 do the P52 after we start PTC at about 56:30.
CC: That's right. Any time after that; it's not time critical.
CDR: Okay. Let's see if I have some of this, Joe. Around 52:30 we're to do the battery charge on BAT - battery B.
CDR: And then about 52:40 we're going to do the LM tunnel vent valve, and the LM/CM DELTA-P which has been written up at 55:40.
CDR: We're deleting midcourse-3 and we've moved up the LM entry to 55 hours. So we'11 merely follow all the - We'11 follow all the procedures that leads up to LM entry that was originally scheduled for 58.
CC: That's correct. You can start at 57 in the flight plan; call it 54 hours and press right on.
CDR: Okay. Then whenever we're finished with the LM, which we anticipate around 56:30, we'11 commence PTC and sometime after that we'11 do a P52.
CC: That's affirmative. And did you copy the new high gain angles for 55 hours? The ones we had - -
CDR: Okay. We're going to stop the PTC for LM entry at roll 285, and high gain angles are pitch 23 and yaw 267.
CC: That's correct, J_m. And, 13, Houston. The computer is yours.
CDR: The computer is ours. We're in BLOCK, and exactly when do you want the TV to be cranked up?
CC: You can crank it up sometime prior to 55 hours at your convenience just to set it up. We'11 be expecting transmission at 55 hours.
CDR: And, Houston, Apollo 13. One thing I missed about the 02 fuel cell purge and waste and water dump.
CC: Roger. We'd like the the 02 fuel cell purge and waste water dump at 54:50.
CDR: Roger. We'11 pick up those items at 54:50.
CC: Ail right, Jack. One thing we'd like to have done sometime soon is to have you cycle the cryo fans in 02 tank 2 one more time. We'd like to see if we can get that sensor back.
CMP: Okay. 02 tank 2 fan on now.
CC: Go, 13.
CDR: We - We have just one question, the LM tunnel vent valve. We're questioning why we're venting until the DELTA-V is greater than 1.7 if we are going to open up the tunnel, then pressurize the LM usually.
CC: Right. Stand by on that.
CDR: Go ahead. ?age ]27
CC: Roger. The word on that, Jim, is that they want to insure the proper 02 concentration in the LM when you get to the surface, and this is a method of doing that by bleeding out additional nitrogen.
CC: And, 13, Houston. If Jack is up, I'd like to talk to him about the P52, briefly.
CDR: Okay. He's here.
CC: Okay, Jack. What they'd like you to do on this P52 at 49 hours, they've been observing a slight Jitter in the optics shaft angle of about 0.2 of a degree plus or minus. Before you come out of the OPTICS ZERO position, at the start of this P52, they'd like you to just observe the shaft readout, and see if the jitter occurs on your direct readout there, and also they'd like you to briefly call up a VERB 16, NOUN 91 so we can look at the shaft and trunnion angles.
CMP: Okay. Let's see if I got it right. On the P52 at 49 hours, before coming out of ZERO on the OPTICS, observe the shaft and also call up 16, 91 and let you look at the shaft and trunnion angles to observe a possible jitter. See whether it occurs in the ZERO position as well as out of ZERO.
CC: Roger, Jack. That's correct; and if you have time, now, I've got a flight plan update for you on looking for the Comet Bennett.
CMP: Okay. Stand by 1, Joe. And the commander's going off the air briefly.
CMP: _ Okay, Joe. I'm ready to copy the ... now.
CC: Okay, Jack. I'm going to read it to you, and then add some comments and we'11 talk about it a little. This should occur sometime after 49:30. After the P52 realine at 49 hours, if time permits we would like the crew to investi- gate while in PTC if there is a roll angle in which the comet can be observed for photos. If there is, record the optimum roll angle for possible photography, prior to reinitiating PTC at 56:30 or so, whenever the guys are done in the LM, use P52 planet option, and the following half-unit vectors for tracking Comet Bennett at about 49:46. Are you ready to copy half-unit vectors? Over.
CMP: Okay. Go ahead, Joe.
CC: Okay. R I plus 0.34202, R 2 minus 0.07374, R3 plus 0.35719. Read back.
CMP: Okay. Copy RI plus 0.34202, R 2 minus 0.07374, R3 plus 0.35719.
CC: Okay. That's correct and the last sentence on the update is that you can expect AOS of the comet at a roll of 45 degrees and LOS at a roll of 155 degrees. Now, the deal here, Jack, according to the plots they showed me is, the comet appears to be about 10 degrees away from the Sun, and due to the geometry of the LM there shadowing the Sun, it would appear that you will be able to see the comet through the sextant without getting Sun shafting between roll angles of about 45 degrees and 75 degrees. It appears that as your roll gets higher than 75 degrees, although the comet is still in the field of view, the Sun is also in the field of view, and you probably will not have any success between 75 and 155 if you haven't got it from 45 to 75. If you do find that you can see the comet some- where between 45 and 75 or 80 degrees, just note that roll angle and then if it's feasible we'd like you to photograph it after the LM entry part of the checklist. Over.
CMP: Okay, Joe. Let me give it back to you and see if I've got it here. After the P52, during our PTC you want us to use P52 and observe Bennett's Comet through the sextant; note a roll angle if we can find it visible. It would be visible somewhere between - ideally between 45 and 75 degrees, and we should lose it about 155 roll, and if we do see it, make an observation of whether it is photographable, note the roll angle for photographs to be taken after or prior to initiation of PTC at 56:30.
CC: That's exactly right, Jack.
CC: We're ready to have to 02 tank 2 fan off, and thank you.
CMP: Okay. Doesn't look like we got it back, huh?
CC: No, it doesn't, Jack.
CC: Hey, 13; Houston. Go ahead.
CMP: Okay, Joe. I've started into P52 here. I've proceeded on option 3, and on the dis - 1520 - 1525 display, I've called up 1691. I'm going to let you observe and see while the - _he shaft angle while the OPTICS are still in ZERO.
CC: Okay. Roger that, Jack. We're looking at it, and I'11 give you a mark as soon as G&C is happy.
CC: 13_ tIouston. Jack, could you give us a readout on your counter now?
CMP: Okay. I'm showing a shaft of 0.2 and a trunnion of 359.92.
CC: Roger. Copy that. Is there any jumping around on the shaft?
CMP: You mean on the TPAC readout?
CMP: As a matter of fact, it went from 0.2 to 0.21.
CC: Okay. Copy that. Stand by 1.
CMP: Okay. Now it went down - It went down as low as 0.15.
CC: Jack, Houston. Let us watch that for another minute or so.
CMP: Okay. I'm in no hurry. It looked like it burned between 0.14 and 0.8 with an occasional spike up to 0.2.
CC: Roger. I 32/2 Tape
CC: Apollo 13, Houston. You can press on with P52 now. Over.
CMP: Hey, Houston, are we clear to torque? Are you reading the torquing angles?
CC: 13, Houston. Go ahead and torque.
CMP: Okay. Time of torquing will be 49 hours 8 minutes 35 seconds.
CC: Roger. For Jack, we missed the star angle differ- ence on the P52. Would you read us that?
CDR: Roger, Houston. It was all balls.
CMP: Hey, Houston; 13.
CMP: Okay, Joe. I got into P52 about 49:34. We loaded the planet - or Bennett Comet vectors into the planet option, and P52 tracked it all the way across except that it was always occulted by the LM, and we're in a roll angle of 155 now.
CC: Roger. We're copying your roll angles. At what roll angle were you able to start tracking it, Jack?
CMP: Okay. At the time we entered it there, we were about 66 degrees roll, so either we started too late, or maybe somehow we got a wrong calculation on the roll angle.
CC: Okay. Let me have G&C comment on that. I sus- pect that the roll angles we gave you were calcu- lated for exactly 90 degrees pitch, and you're probably wobbling enough that they're not exactly correct. Paf_e 13__

CC: 13, Houston. Over.
CC: Okay, Jack. Notice you've secured from that, and that was going to be our recommendation, anyway. We're going to have the guys in the back room look at it and see if they can come up with some - with some better numbers based on the cone angle that - that you're traveling through, whether there are any roll angles that - that are available to you. And if there are, and we have time, we might give it another try; if not, we just will forget it.
CC: Okay, Jack. I'd like to pass you a switch con- figuration on the CRYO 02 TANKS and give you the reason. Right now, wetd like you to go to HEATERS tank 1, OFF; tank 2, AUTO, which is the opposite of the way you've got them now. Over.
CMP: Okay. Is this 02 or H27
CC: This is 02, and stand by for a minute azld we'11 have a - Excuse me. This is H2, Jack; it's H2.
CMP: ... is AUTO, ... 2 OFF.
CMP: Okay, Joe. Do we have you back again?
CC: Okay, Jack. We're getting you back, and I hope you copied my - my correction of my mistake. I'm talking about the H2 CRYO TANKS. We'd like the tank 1 HEATER to OFF; tank 2 to AUTO. Over.
UNKNOWN: Okay. We lost you again. Here's our heater configuration now. H 2 HEATERS 1, OFF; 2, AUTO. Both 02 HEATERS are in AUTO.
CC: Okay. That's the configuration we want you in, and here's what we're thinking about. When we went to tank 1 AUTO, tank 2 OFF; we found that the heater cycle had a tank 1 pressure of about 233 psi, which is well above the caution and warning limit, and if we go to that configuration for sleep, we'11 keep from getting CAUTION AND WARNING lights dltring the sleep cycle. Okay. In order to do that comfortably, we want to spend the rest of the day using more H2 out of tank number 2, so as to get an unbalance in favor of tank 1, so at the end of the sleep cycle it'11 all come out even. And that's why we have you in t_k 1 OFF, tank 2 AUTO, now. We expect to get about a 3-percent unbalance over the next 10 hours; and prior to sleep, we'11 call you to reverse the configuration again. Now the only disadwmtage here is that, during tile day, you will probably get a few CAUTION AND WARNINGS, and we just figured it would be better to get them now than while you were sacked out. Over.
CDR: I'11 buy that 100 percent.
CC: Okay. Good deal. One other detail for you, Jack; G&C tells us that the OPTICS jitter is very similar to what we had on Apollo 12. It's no problem, but when you're not using the OPTICS, we recommend that you turn the OPTICS POWER switch to OFF to guard against a possible degradation as the flight progresses. Over.
CC: Okay. Apollo 13, Houston. I have one more little update for you, and it's another update to the erasable memory onboard crew charts on page G/9-2. Over.
CDR: Houston, 13. We're ready to copy.
CC: Okay, Jim. These are gyro compensation terms. They've already been uplinked, and we're just updating your onboard charts now. In column A, number 11, change from 77646 to 00114; number 12, change from 77332 to 77546; number 13, change from 76617 to 77201. Over.
CDR: The changes are as follows, and all in column A: number 12, the new change is 77546; number 11, the new change is 00114; and 13, the new change is 77201. Over.
CMP: And, Joe, do you know - Are you going to try and let us spot the Bennett Comet on this next revo- lution there? Or do you want me to turn the OPTICS power off now?
CC: Stand by 1, Jack. Okay, Jack. We don't have confidence _n those roll angles yet, so why don't you turn the OPTICS off, and we'11 update you later.
CMP: Okay. Going off now.
CC: Roger. Taf_e 33/i [ _ ,U .L )/J
CC: Roger, Jim. If you've got a couple of minutes now, I'd like to read up to you the change to the LM entry procedure that we'd like you to observe at 55 hours, and the rationale for it. Over.
CDR: Okay, Stand by.
CC: Okay. Before you start copying, this procedure is - is basically simply to activate the super- critical helium pressure gaging so that you can _ead it. And the concern here is lest this supercritical helium pressure reach 1800 psi by 103 hours, at which point we'd be within a pos- sibility of rupturing the burst disk when you activate the DPS. Now, based on the pressure at launch, and based on a nominal rise time of about 6-1/2 psi per hour between then and now, the pres- sure should read about 710 psi. Stand by, 13, until we get better COMM.
CDR: Houston, you were cut out. Would you say again about the helium pressure.
CC: Roger. Based on the prelaunch pressure in the SHe tank and the nominal rise time of about 6-1/2 psi per hour, the pressure should be about 710 at 55 hours. Are you reading? Over.
CC: Jim, Houston. Did you read that last?
LMP: Okay, Joe. I 'm on OMNI C now. How do you read?
CC: 13, Houston. You're loud and clear now. INCO tells me he's having a little problem at Goldstone and wants me to stand by for a minute.
LMP: Okay. How do you read now, Joe? I'm going from OMNI C to D now.
CC: You're still loud and clear on - on D, Fred. Stand by 1.
UNKNOWN: Okay. i'11 put her back to OMNI B if you all want to take command again?
LMP: And the last thing we heard, Joe, was that tile SUPERCRIT should be reading about 710 psi.
CC: Okay. That's the last thing I passed up. And while we're waiting for INCO to decide here, let me continue. The deadband that is considered acceptable is between 660 and 770 psi. In other words, any rise time that'11 give you one - a pressure between those two, will keep you below the critical pressure at 103 hours or so. So, we expect it to read in that - in that band and if it does, there will be no problem. If it reads between 770 and 800 psi, we will want you to check the pressure again at about 59 hours, and I'11 get the detailed procedures in a minute. If the pressure is equal to or greater than 800 psi, we're going to have to go into some more detailed procedures; we're going to try to - to get PCM data on it, for one thing. We may have to have you sit there and stare at the gage for a while to find out when it clicks up and get an accurate rise time on it, and then in extreme case, we are even thinking about a DPS burn, but we don't really think that will happen. Now, if you are ready to copy, what I have for you is a change or an addition to the LM Activation check- list between pages TLC-1 and TLC-2, which consists of seven steps, and if you can find a blank side to write it down on, I would like to pass it up. Over.
LMP: Okay. How do you read on OMNI C, now?
CC: Okay. You're loud and clesx on OMNI C. Stand by 1 while we get INCO synced up.
UNKNOWN: Okay. The rest of your update was that it's okay if it is anywhere between 660 and 770 psi. If it's above 770, you are going to ask us to con- sider going back in at 59 hours and either get PCM going or sit there and give you gage reading changes on the basis of that. And you said some- thing about an extreme measure. We may have to consider some sort of DPS maneuver.
CC: That's correct, Pred. We don't have procedures for that yet, and we don't have any real expecta- tion of getting into it. The procedure i'd like to read up to you now is simply the :;t_ps req_ir_d to get the supereritical helium pressure reading, at 55 hours. Over.
CC: Okay. We're calling this TLC-lA, step 6, "Transfer to LM power."
UNKNOWN: right. Stand by 1, Joe.
CMP: Okay, Joe. He's ready to copy.
CC: Okay. Step 6, "Transfer to LM power (floodlights blank), CAUTION WARNING POWER CAUTION light ON. Report GET to MCC. Panel 11, CIRCUIT BREAKER EPS TRAESLUNAR BUS TIE, CLOSED. Circuit breaker panel 16, EPS TRAESLUNAR BUS TIE, CLOSED. Cir- cuit breaker panel 11, LIGHTING UTILITY, CLOSED. And activate utility lights." Over. And, 13, Houston. Select OMNI Bravo, please.
UNKNOWN: Okay, Joe. I 'ye created a new page here called TLC-lA, item 6, Transfer to LM power and the usual check that the floodlight's blank and that I 'ye got the CAUTION WARNING POWER light ON; I get a GET from Jack, and I will pass that on down to you. Item 7, CIRCUIT BREAKER EPS TRANSLUNAR BUS TIE, panels 11 and 16, CLOSED. Step 8, circuit breaker lighting and utility on panel 1, CLOSED, and turn on the utility lights. However, the lighting is such that I don't really need those. They are in stowage, right now, I guess, in the ISA, and I'11 probably Just leave them there.
CC: Okay. That's optional. The way we had page TLC-lA written, that was all part of step 6. You haven't even gotten to step 7 yet. Step 7 is as follows.
CC: Fred, Houston. Are you with me?
CC: Apollo 13, Houston. Are you reading me now?
LMP: Okay. Houston, 13. How do you read?
CC: 13, Houston. Loud and clear. What OMNI you ot_ now?
LMP: I'm going to stay OMNI B, if you all want to take command back and you can let INCO jockey them around between B and D. And how many steps we got, so I know whether to write big or small here, Joe?
CC: Okay. We got steps 6 through 12, but step 7 is the same size as 6, and 8 through 12 are short. They're only one line each.
CC: Okay. Step 7 follows: "Circuit breaker panel 11, AC BUS B, HELIUM PQGS PROPELLANT DISPLAY, CLOSED. Circuit breaker 11, AC BUS B, NUMERIC LIGHTIi_G, CLOSED. Circuit breaker 11, AC BUS B, BUS TIE INVERTER l, CLOSED. Circuit breaker panel 11, EPS INVERTER l, CLOSED. Circuit breaker panel 16, INSTRUMENTATION SIG SENSOR, CLOSED. INVERTER l" - -
LMP: Hold on a minute, Joe.
LMP: My shorthand is rather poor today.
LMP: Okay I'm now up to circuit breaker panel 11, INVERTER 1, CLOSED.
CC: Okay. Next was "Circuit breaker panel 16, INSTRUMENTATION SIG SENSOR, CLOSED. Then IN- VERTER l, SELECT. Then HELIUM MONITOR to SUPER- CRIT PRESS. Report SUPERCRIT PRESS to MCC." Over.
LMP: Houston, 13. How do you read?
CC: 13, Houston. You're coming through. We still have some background noise. Do you want to read back step 7?
LMP: Hello, Houston; 13.
LMP: Okay, Joe. The last thing I got was HELIUM MONITOR to SUPERCRIT PRESSURE.
CC: Okay. The last part of step 7 is, "Report SUPERCRIT PRESSURE to MCC," and read back step 7.
LMP: Okay. Step 7. Circuit breaker panel 11, AC BUS B, HELIUM PQGS DISPLAY, CLOSED. Main - Circuit breaker panel 11, AC BUS B, NUMERIC LIGHT- ING, CLOSED. CD panel 11, AC BUS - Is that AC BUS B? BUS TIE INVERTER 1, CLOSED?
LMP: And CB - CB EPS INVERTER 1, panel 11, CLOSED. CB panel 16, INSTRUMENT SIGNAL SENSOR, CLOSED. INVERTER l, SELECT. HELIUM MONITOR to SUPERCRIT PRESSURE. Report pressure to MSFN.
CC: Okay. That's correct. Now step 8 is, "On MCC request, perform step 9." In other words, you wait for us to decide what to do and that's according to the gouge we've already given you. And step 9, I'11 give you now, is "HELIUM MONITOR to OFF, INVERTER to OFF." Over.
LMP: Okay. Step 8 says, "Set in an MCC hold." Step 9 says, "On MCC' s words, HELIUM MONITOR OFF, IN- VERTER OFF."
CC: Roger. That's correct. Step 10 is, "Configure circuit breaker panels per Activation 3 and 4."
LMP: Okay. Configure - step 10, "Configure circuit breakers per Activation pages 3 and 4."
CC: Roger. That's correct. Step 11 is, "Deactivate the utility lights if you activated them," and step 12 which is the last one is, "Transfer to CSM power, usual observations, and report time to MCC."
LMP: Okay. Step 11, "Deactivate utility lights." 12, "Transfer to CSM power and note the usual observations and report the GET."
CC: Okay. That's it. And, of course, Houston will be requesting you to go to step 9 if the pressure is less than 770. If the pressure is between 770 and 800, we will be asking you to do the following, if you're ready to copy.
LMP: Stand by. I've got to find some more blank paper.
CC: Y¢_z. This i:;going to b, page TLC-iS, }Jut it's very short.
LMP: Okay. Go ahead with TLC-3.
CC: Okay. Stand by 10 seconds, Fred.
LMP: Ail right. Go ahead.
CC: Roger. We'11 hold off on that. Ii;was a short three-step procedure which said, "Repeat activa- tion pages 1, lA, and 2, "but there was another step in it that nobody understands. So, essen- tially what we'd recommend in that ease would be that you would repeat the procedure that we just passed up for reading the SUPERCRIT pressure. If we need to, we'11 clarify it later on. And that's all we've got.
CDR: Okay. One thing, Joe; I Just want to doubleeheck again. All the stuff that normally was going to start at 57 hours, which the first item was pres- surize CSM to 5.7 psia, we're going to move that up to 64 now, so we have our LM entry which was nominally at 58 at 55. Is that correct?
CC: That's correct, Jim.
CC: Roger, 13. Because of the 02 tank 2 quantity sensor drop out, EECOM wants to keep a little closer track of the cryo quantities, and he's going to be asking you to stir all the cryo tanks at slightly more frequent intervals than had been planned, and the first time is now, and we will be calling you probably every 5 or 6 hours, ex- cept during sleep period and high activity periods. We'd like you to do it now. Over. Tape '_ _
CDR: Okay. We'11 start it ... now.
CC: And, lB, Houston. For your information, a normal 1-minute or so stir will be fine. 34/1 Tape
CC: Jim, just an advisory; expect a CAUTION AND WARNING on H2 tank 1 pretty quick. No problems; Just warning you about it.
CDR: Okay. A zero pressure light on H 2 tank 1 coming huh? on shortly,
CDR: Okay. Well, you're pretty close. It Just came on.
CC: Any other predictions you'd like?
CDR: Well, there's - I guess there's all sorts. Could you go to the horse races with me?
CC: I'm sorry; you were garbled. Say again?
CDR: I said I'd like to invite you to the horse races with me.
CC: Right. We'11 - We'11 send EECOMM.
LMP: Well, it's time for a little grits again here, Vance.
CC: Understand. Some grits, huh? Chow. Bon apetit.
CC: Roger. Just expect that same CAUTION AND WARNING to come on again. And you want us to keep warn- ing you of that thing?
CC: Roger, Jim. Just expect a CAUTION AND WARNING to come on the same as it did about an hour ago.
CDR: Go ahead, Houston. We've lost ...
CC: Roger. How are you reading me now, Jim? 3_/2_ Tape Page lh3_
CDR: Houston, Apollo 13. \ \
CC: 13, Houston. How do you read now?
CDR: Okay. Read you good now. Seems like we've had a little trouble with the COMM today.
CC: Yes. I guess it's partly because you are further % out. We just wanted to tell you that you were % going to get that CAUTION WARNING that you Just \ got. Right. We Just got.
CC: And I won't bother you with those calls anymore, unless you especially want them.
CDR: That's okay, Vance. You don't have to call us about that, unless it's something serious.
LMP: We Just ate a can of ham salad and that was an experience.
LMP: It's really kind of like eating on the sly. Chasing it around.
CC: Right. Copy.
LMP: But good. TAPE END OF
CDR: Right, we're not doing anything right now, Vm_ce, we're Just getting curious, we could start the LM entry procedures, and get everything squared away, and then when the TV comes up at 55 hours, we can Just use it for the TV, and we wouldn't be worrying about checking out the SHe tank pressures and everything like that.
CC: Okay, let us mull that one a minute here, and I'11 get right back with you.
CDR: Also, Houston, Apollo 13. We'd like to move up the waste water dump and maybe the 02 fuel cell purge a little bit early, if we could.
CC: Jim, you're clear to go on into the LM, and just advise though that the TV time is still fixed at 55 hours, and - so we'11 be standing by to support your entry and we'11 get back with you on a minute - in a minute on the 02 fuel cell purge and the waste water dump.
CC: And also request your LM/CM DELTA-P which was on the flight plan for 53 hours. What did you vent it down to? Over.
CDR: We have 1.7 now. We vented it down to that figure.
CC: Okay, you vented down to 1.7, and what did it start at?
CDR: It was about 1.1, Vance.
LMP: What do you read for suit pressure down there?
CC: We're reading 4.3, Fred.
CC: Go ahead, Apollo 13.
CDR: We'd like another confirmation, when we closed the tunnel vent valve back to LM/CM DELTA-P, we were reading about 1.7 - 1.75, and it slowly went up now to about - oh, I'd say a little less than 2.2. Seems to be holding there - Is there a lag in the gaging system?
CC: Okay. We'11 - we'11 ask that question. Stand by.
CC: Okay, to answer your question, Jim, that increase in pressure is normal, because it was just track- ing an increase in cabin pressure.
CDR: We're not thinking today.
CC: And, 13, from Houston, it's okay with us if you want to move the 02 fuel cell purge and the water dump up to this time. Over.
CDR: Okay. We'11 work it in shortly. Thank you.
CC: Jim, recommend you stay in the PTC until we stop it for the TV at 55 hours, in case you were thinking of - -
CC: Roger. Recommend you continue PTC until 55 hours. Over.
CDR: You were calling, Houston?
CC: That's affirmed, Jim. How do you read now?
CDR: Okay. We read you loud and clear.
CC: Okay. The only comment that we Just made was that, in case you were thinking of stopping PTC, there's no need to stop it until 55 GET when TV starts.
CDR: Right. We'11 stop it when we're setting up our TV.
CMP: Okay, Houston, the waste water dump and 02 fuel cell purge are complete.
LMP: Okay, Houston, the LM/CM DELTA-P is constant. We're going to go ahead with hatch removal.
LMP: Is that you, Jack?
CC: No, this is Jack's replacement.
CC: This is Houston. Go ahead, 13. _'age 147
CC: Roger. Go ahead, 13.
CMP: Okay. The LMP has entered the LM.
CMP: Is that Big John?
CC: It sure is. How're you doing?
CC: Yes, you're doing great, man.
CMP: Thank you. I had a good CDR.
CC: You're doing it on your own now.
LMP: Yes, it feels like I'm back at home, again, John, down in here.
CMP: I hope you did a good job, John.
CMP: Okay, Houston, we want to take the FM and bring up TV here for our own use. Then we'11 go to TRANSMIT i - at 55 hours.
CC: Roger, 13. l_'ag_ J 4L_
CMP: Okay, Houston, we've transferred to LM power; the time was 54 hours 46 minutes 15 seconds.
CC: Roger, Jack. Transfer to LM power. Thank you.
CC: And the docking-tunnel index, Jack, was minus 2 degrees.
CC: Say again, Fred, you're coming in with a lot of background noise.
LMP: Okay. The docking-tunnel index mark was minus 2 degrees.
CC: Roger. Minus 2 degrees.
LMP: Okay. Jack, how do you read?
CC: Fred, Houston is reading you loud and clear.
LMP: Okay. I've got up through step 7 now, and I'm not getting much of a light in the helium indi- cator here. Why don't I review for you how we've proceeded, and you look at the procedure and you gave me, see if we've missed anything.
CC: Roger. Go ahead. okay. I'm staring at a CAUTION AND WARNING FOTw_ER light, and all the red flags; and we got both X LUNAR BUS TIE breakers IN. The UTILITY LIGHTING breaker is IN; then AC BUS B HELIUM PQS DISPLAY; the AC BUS B NUMERIC LIGHTING, and AC BUS B INVERTER i is - BUS TIE is CLOSED. Then I closed the INVERTER i breaker, and I've selected, on panel 16, and the SIGNAL CONSENSOR [sic] breaker is in; I've selected INVERTER i and put the HELIUM MONITOR switch to SUPERCRIT and I have no lights.
CC: Okay, Fred, let us take a look at it.
LMP: I was wondering, do we need an A - do we need, possibly, in the - one of the ANUN/DOCK/ COMPONENT breakers in?
LMP: Okay, Jack. Hold the phone. I forgot the rheo- stat was cranked all the way down on the ANUN/ NUM and it's showing 720, which looks like a pretty good - pretty good number.
CC: Roger. We copy 720. Thank you, Fred - -
CC: Flashed to 7 - Okay, and it Just flickered down to 710. It's kind of flickering between 710 and 720.
CC: Roger. 710 to 720.
CC: Okay, Fred. Those are good numbers, and we're not going to have to crank up the TM. That's the number we were looking for.
LMP: Very good. Okay. Do you want me to back out of this in reverse at least as far as getting this part of it powered down?
CC: Fred, this is Houston. Go ahead and back out of this little test and proceed.
CMP: Okay. We're back on CSM power. The time was 54 hours 58 minutes 50 seconds.
CC: Roger, Jack. 54:58:50. Thank you.
CMP: Okay, Houston, we'11 try to pick you up on the high gain.
CC: And, 13, we're ready on the TV when you are.
CDR: This is 13. Say again, Houston.
CC: 13, we're ready on the TV when you are. Any time.
CDR: Okay, sounds good. With you in a minute, we're Just cranking up high gain now.
CDR: Okay, Houston. How do you read us in the high gain?
CC: We're hearing you 5 square, Jim, how me?
CDR: Okay. You're coming through okay.
CC: As you were on that, Jim. We don't have you on high gain yet. We're still looking at you.
CC: 13, Houston. In this attitude, we'd suggest pitch 5, yaw 237 on the high gain. Over.
CDR: Pitch 5, yaw 237. Roger.
CMP: Okay, Jack. Can you - can you read the high gain now?
CC: Affirmative, Jack. We've got you on a high gain and it appears to us that we're in wide beam - wide beam width.
CMP: Yes. We can't get it to come down to narrow. We tried to switch to AUTO track or REACQ, and it - yaw drives around from 270 to 0. And pitch goes from about 6 degrees around to 90. I'm trying - we're fitting it manual now at the angles that you gave us, and I'11 try and get you in medium and narrow beam widths picking it up manually here.
CC: Roger, Jack. Meanwhile, we'11 look at the situation you describe there.
CMP: Okay. And it does it on both sets of servo electronic power.
CMP: Jack, what it looks like is that, when we hit 239 degrees at this attitude, it hit some sort of scan limit or something and drops off.
CC: Roger, Jack; thank you.
CMP: Okay, I'm trying you in wide or medium beam width now.
CMP: Can you pick up the TV in this condition here at all?
CC: Negative, Jack. We'11 have to have the narrow beam width.
CMP: Okay. Can you give us, maybe, a slight maneuver?
CC: Jack, we'd like you to check two high gain circuit breakers down in panel 25. Check your high gain group 2 and your high gain in the flight bus. Over.
CMP: Okay. Okay, Jack, they're both IN.
CC: lB, we've got an attitude suggestion for you. We suggest that you go to roll 285 and try pitch 90 and yaw 0. Over.
CDR: Okay, Houston; Apollo 13. I think we've got high gain locked up now. Do you confirm?
CC: We confirm that, Jim, we've got you locked up on the high gain and narrow beam.
CDR: Okay, sounds good. We'11 get the TV started right away.
