CDR: Well, you're watching the world's leading expert on P23.
CC: Well, I don't know. Jack Swigert wrote a paper on it.
CDR: We're aware of that, also. Comment still stands.
CMP: Yes, that has nothing to do with Al's comment, Bruce.
CC: Okay, I'11 pass that along.
CDR: Bruce, you're also watching the world's leading expert on going from CMC AUTO to FREE and back.
CDR: Houston, 14. We are applying power to the dump, AUTO heater, at 167:25, and we'11 be doing the test in about 30 minutes.
CC: Roger, Houston. Roger, out.
CC: 14, this is Houston. We show that you're in HIGH GAIN ANTENNA coverage area at the present time. We'd like you to acquire on the HIGH GAIN; PITCH, minus 5; YAW, 250. Over.
CDR: Okay, we're shooting for that now. We're at PITCH, minus 5; YAW, 250.
CDR: Okay, you should have it now, Houston.
CC: Roger, Al. We've got you loud and clear.
MCC: Roger, Al. I just wanted to say, that I get a chance to say hello on the network. You guys did a great job yesterday, and I think things are in beautiful shape coasting home.
CDR: Well, thank you, Thomas. Appreciate those kind words. We're coming along well up here, too, right now.
MCC: Yes. Stu's marks looking real good, and we had a great team effort on that landing; we'11 tell you about it. In fact, I nearly lost all of my hair; would you believe that?
UNKNOWN: CDR (Laughter) No, that would be pretty hard to be- lieve, Tom.
CDR: Now, we're pressing ahead with the flight-plan items here, and we're staying busy.
LMP: Okay, back to our ISA weight problem.
CC: I didn't know we had a problem, but go ahead.
LMP: Okay, I was jumped on by both sources, here; it's not a problem; it was a question. The ISA contains the 50 pounds we measured on the surface, less the lO0-foot tether, plus the 70-millimeter camera and magazine, plus a pair of EVA gloves, plus the return items on Deke's list.
CC: Okay, Ed. We've got that, and we'11 work the arithmetic on the weights from down here and keep you advised. Over.
CMP: There you go, Bruce.
CC: Okay, Stu. We copied that one for posterity.
CMP: You got the last one, Bruce?
CC: Yes, we got that one, too, Stu; but you only get the first one framed and authenticated.
CC: You still on Delta Sagittarii?
CMP: That's negative. That was the last mark on Antares.
LMP: We're starting the 02 test now. The heaters are going to AUTO. Opening up the flow valve.
LMP: Delay that. We're standing by to open up the flow valve. It's not open yet.
CC: Okay. Understand, heaters to AUTO; and you're standing by on the flow valve. Have you got the REPRESS package valve, OFF?
CDR: Yes. We're changing that now.
LMP: Okay, Houston. The plug is up; we're flowing at 168:09:50.
LMP: The screen has been installed on the adapter.
CC: Roger, the screen.
CC: Apollo 14. Stu, this is Houston. Over.
CC: Okay. We continue to get praise of your ability on the P23s. Based on your navigation, your idea of your gamma angle at entry interface is minus 6.1 degrees. The MSFN solution corrected for the midcourse 5 burn, but without any postmidcourse tracking is 6.6 degrees. Over.
CMP: Okay. Yes, I noticed - I was comparing a VERB 83 there, Bruce; and I showed 625 miles, or there- abouts, prior to those last two sightings; and then, it was down to - I don't know 100 and some - after that. I think the sightings on the Moon is what really help bring it in. There were a couple of large updates there, I think, that really helped it.
CMP: CC Okay. That sounds like you're doing good work.
CC: 14, this is Houston. On telemetry, we're showing a cabin pressure of 4.7 right now and wonder what you've got?
LMP: That's about 4.8, what we're showing, Bruce.
CC: Okay, 14; Houston. Now, we're showing the surge tank at 750 on our telemetry, now.
CDR: As a matter of fact, we were just going to call you on that. We have a bias on our gage, that's good, we'11 stay with - we're going to start the test at 168:30 - 168:29 - I'm sorry, 168:30:00, surge tank valve going OFF.
CC: i4, this is Houston. We'd like you to zero the optics, please.
CDR: Okay; stand by. Okay, you've got it.
CC: Roger; thank you.
CC: 14, this is Houston. We're showing an 02 manifold pressure of 8 pounds per square inch absolute, and we'd like to terminate the 02 high-flow test at this time. Further procedures found in your flight plan opposite 171 hours OO minutes GET, deleting the 10-minute step in there - deleting the 10-minute restriction in there. Over.
CDR: Okay. At _71 hours, we ... through termination procedures; got you.
CC: 14, this is Houston. We show the surge tank on line and the manifold pressure back up in the nor- mal operating range, and we'd appreciate it if you'd advise us when you have the orifice closed ofi'. Over.
LMP: Roger. It's closed off, now.
LMP: Bruce, what was the reason for terminating the test? I didn't quite understand it. manifold,
CC: Okay. The pressure in the 02 which nor- mally is regulated 85 to 110, got down to 9 psia; and the pressure in your water tanks was falling off from below its regulated range because of the pressure in the manifold. And we just thought it best to terminate the test at this time and reexamine the data that we've got on the plumbing leading down to it, and we'11 be back to you with some info on it later. Over.
LMP: Okay, we understand. Thank you.
LMP: Do you want us to stay in this attitude, or shall we go on to the thermal attitude?
CC: 14, this is Houston. Remain in the present atti- tude until 171 plus 30, and then maneuver to the thermal attitude. Over.
LMP: Okay, and what about the isolating of the tank? Do you want to go ahead with those three steps, or do you want to hold off on those?
CC: Stand by on that, Ed. We'11 have the answer for you in a minute.
CC: 14, this is Houston. Affirmative. Press on with the tank 3 isolation valve opening. Over.
LMP: Go ahead. Houston.
CC: 14, this is Houston. Back when you all were run- ning that P37 about an hour ago, we took your state vector and ran it through our computer here; and we got excellent agreement between the two solu- tions. We both showed a 0.9-foot per second mid- course, and the entry interface times were within 1 second of each other. The reduction here shows that the measurement plane error in the star sight- ing's themselves was less than 3-arc minutes. So, it's really looking beautiful.
LMP: Three-arc minutes, huh?
LMP: Well, that's very good, Bruce. Thank you.
CC: And, with respect to the 02 high-flow test, the feeling down here is that low pressure in the man- ifold was probably connected with some panel 251 activity, giving a higher flow rate. And if Stu's around, we'd like to discuss for a minute his plans on the demonstrations. Over.
LMP: Okay. He's here. Just a minute; we'11 put him on.
CC: Okay, Stu. We wanted to just get a status report on the DEMOs, if you've-been doing any work on them on the way home, here, and see what your plans were for the TV show this evening.
CDR: Okay. N_y don't you give us about an hour on that; I'm just in and out. We've been running some of the metal composites, but that - that's nothing to do with TV; all we're going to do there is just show the experiment and talk a little about it. And when you called, I was putting up the heat-flow experiment. We're going to take a look at that one and the liquid transfer and get a hand on it. So, I'11 have some word in about an hour.
CC: Okay. We're standing by for the TV at the regular time; and if you could tell us which ones of the metal casting that you've already run, why it might be of interest to people down here. We caught num- ber 4 on the way out.
CMP: Yes. We've run 4, 5, 6; and 7 will be the next one.
CC: 14, this is Houston. Go ahead. Over.
CDR: Just to clarify a point. We're still planning on starting the TV show at 172:30. Is that correct?
CC: Okay. We'd like to confirm that you did, in fact, turn the heaters and oxygen tank number i off for the continuation of our 02 low-flow test here.
CDR: We're working on a 50-pound instrument error on that. I think we're reading about 865 right now. How do you look?
CC: Okay. We're reading a little higher down here. Got about 889 showing on the TM.
CDR: Okay. That's fine. We'11 turn it off now.
CC: Okay; Roger. And for Ed, the folks in Kingston Court wanted me to say hi.
CDR: Understand you want Ed on the line.
CC: No, just pass that on to him, and you might remind Stu to listen to his music.
CDR: Yes. We - we're listening to the music.
LMP: Houston, 14. This is Ed. Did you call me?
CC: Ed, this is Houston. Go ahead. Over.
LMP: ° Roger. Did you call me?
CC: I just wanted to say that the folks in Kingston Court said to say "Hello." They'11 - -
LMP: Thanks, Bruce. Appreciate that.
CC: They'11 be watching during the TV demonstration here.
LMP: Very good. We're - getting the camera out right now, as a matter of fact.
CC: Ed, if you have a couple of minutes, we have a short test we'd like to run on the HIGH GAIN ANTENNA to answer the questions - some questions that the antenna people have and try to tie down a couple of questions that are still in their mind about it.
CC: Okay. What we'd like you to do is set the dials to PITCH of plus 25 and YAW, plus 265, and then go to MANUAL and WIDE and then switch to the PRIMARY HIGH GAIN SERVO ELECTRONICS and try to make a normal reacquisition on the PRIMARY ELECTRONICS and hopefully, if it's working, we'11 wind up - once you acquire backup in AUTO and NARROW. If you have any problems and it won't work properly, just go back to SECONDARY ELECTRONICS and back essentially in the mode you are in now. They want a - one final check on whether PRIMARY ELECTRONICS had indeed failed or not. Over.
LMP: Okay. It seems to have popped right up very nicely this time.
CC: That's in PRIMARY, right?
CC: Okay. We'd like to just stay in PRIMARY then, please.
CC: Okay, Ed. That's really all they had to ask you to do. If you have any sort of failure in AUTO TRACK and PRIMARY, then go back to SECONDARY. Over.
MCC: Yes, how's your health up there today?
CDR: Oh, we're just fine, Deke. Everybody's in great shape. We had a little sleep last night. Everybody's a little bit tired after 2 full days, but we're fine now. And we're making preparations to run the TV show here. We're playing with the experiments a little bit ahead of time to get organized. And we're just going along fine.
MCC: Outstanding. You guys did a beautiful job and you sound great.
MCC: We've got one - -
CDR: Okay, thank you very much, Deke.
MCC: - - we've got one quick question here. Wanted to know how you feel at this point about doing that Q and A with the press tomorrow?
CDR: Sounds good to us. No problems at all with that.
MCC: Okay, real fine. Well we're looking - -
CDR: I think we ought to work out a time - I think we ought to try to work out a time somewhere in the time line when it's convenient for everybody; the people on the ground and for us also.
MCC: Okay, well Flight thinks about 195:30 looks like a good time from all respects down here.
CDR: About 195:307
CDR: Looks pretty good to us Deke. That's good spot in the time line from our point of view, also.
MCC: Okay, real fine. And they'd like to have TV with that. That gives us good coverage out of Goldstone for that.
CDR: Okay, we'11 plan on that, then.
MCC: Okay, great, Al.
CDR: You sound pretty good yourself. How's your sleep level these days?
MCC: Well, I gained on you last night. I picked up about 12 hours.
CDR: Ho ho ho.
MCC: Talked to your bride today and saw her yesterday. Everybody's doing great familywise.
CDR: That's good. Thank you, sir.
MCC: You bet.
CC: We'd like to have you go to the thermal attitude as shown at 171:20 in the flight plan. Over.
LMP: The flight plan showing a NARROW DEAD BAND. Is a WIDE-band DEAD BAND good enough right now?
CC: A WIDE DEAD BAND will be good.
LMP: Roger, thank you.
CDR: Okay, Stu ... now.
CC: Apollo 14, Houston. We're ready for you to ter- minate the charge on battery B.
CMP: Okay, terminating B at this time.
LMP: Houston; Apollo 14.
CC: Apollo 14, Houston. We're getting a very nice picture of Apollo 14 patch. Over.
LMP: Very good. How are you this afternoon, Gordon?
CC: Fine. Gold Team's at your service and standing by for your show.
LMP: Okay. We'd like to welcome you to an afternoon Sunday with Apollo 14 - a afternoon, by the way, with Apollo 14. And we're going to present some experiments for you. And our narrator for this afternoon will be Stu Roosa; and, I guess, he's about ready to go. Stu.
CMP: Okay, Houston. What we'11 try to do this after- noon is show you four of the experiments that we're carrying on board; and even though we'd like to think that maybe they're a major breakthrough - Essentially what these are, are experiments to check out not only the theory involved in the zero-g environment but also the technical problems that we may face in designing bigger and better experiments for Skylab. And three of these experi- ments deal primarily with convection or, in our case, lack of convection, we hope, during the zero-g. And now, for the purists out - of you in the audi- ence that say we should be calling it zero g, we'11 concede to that and go ahead and call it zero g anyway, just for clarification; and everybody knows what we are talking about. But, really, what we're talking about is a free-fall situation, or the lack of weight. So, of course, on Earth under a one-g field, when you heat something, air, so forth, why, we say air rises; and this is due the influence of gravity on the - on the air that becomes less dense; and the cold air comes underneath; and you have your convection patterns, which everyone is familiar with. Well, under our situation, we probably have a lack of, or we do have a lack of these convection pat- terns; and we're going to use this to show some ex- periments and, hopefully, how in later missions that we can manufacture products and, perhaps, medicines and so forth. And the first one of these is the heat flow - it's a heat-flow experiment that we've got mounted over here, if Ed will put the camera on it. And what we have here are various cells; and, maybe, A1 can point them out there on the ra- dial zone. And inside each one of these zones, as - as outlined here, is a heat-sensitive material. And it will change colors as it's heated. And they'11 not all change at the same time due to the substance that the sensor is made out of; however, these two are exactly the same. And, now, under a g-field, if you had - had these two the same and you heated them, well, of course, the hot air would rise. And let's say that you had this sitting on the table, the one above it you would see a - a marked differ- ence in the heating pattern. Here, under our weightless condition, the pattern should be the same. In other words, in these two cells, the heating should go out evenly on both sides. Now, you will see a difference on - on these two because of the sensor being of different material. So, if A1 will throw on the switch - and we'11 see some response from this. It'11 take about a minute. And, while we're waiting for that, we have essen- tially the same thing in a different form, across the top. And we can only heat one at a time; so, we'11 heat up this radial zone, first - I think you'11 have a better chance of seeing this. And maybe, we'11 throw - heat this up and throw it on - put the TV camera on them later. And while - while that's heating up, I'd like to show you another one that - that we've got. Okay.
LMP: Houston. Color check on the picture - How's it coming through to you now?
CC: We're getting a pretty good picture, Ed. But we're not noticing any difference in the crystals in the - circular heat-flow crystals, there - -
LMP: They aren't going to show up on it, yet - so you wouldn't.
CMP: Over here, we've got a - another experiment. Well, let's take another one of the convection types. Let's take the metal castings there, Al. Okay, A1 has now got the - another experiment which we call metal composites. So, we have 18 different samples. These samples are metal. And really, what this experiment is, is to get some data - Okay. How's that picture, now, Gordon? Can you see the metal composite experiment?
CC: Yes. Now, I have settled, and we're seeing it very well.
CMP: Okay. What we have are 18 of these small canisters, each one containing a different metal and/or a mix- ture. And the purpose of this experiment is to get some data on casting under our weightless or zero-g conditions. And here again, when you cast metals, you heat them; and when they cool, you have convec- tion currents in them. Hopefully, here in our lab- oratory, we can heat these and cool them - They will have even cooling. And also, another part of this experiment is, some of the metals are mixed with and/or fibers various other particles. And the theory here, to increase the strength of the cast- ing with these fibers. Now, on Earth, under a one-g field, this gets to be a rather difficult process because, during the cooling, the fibers settle out; and you don't get a homogeneous mix and a cooling; so, you don't have equal strength. So, what we do is, we heat these up and then we run through various processes. Some of them we shake; some of them we don't shake; and then, we cool them. We put them on a little heat sink, here. And we'11 let it set and cool for a certain period of time; and then, we'11 change it, put in another casting, and press ahead. There's really not much else to show on - on TV with - with this one. It's - it takes quite a bit of time, by the time we run through all the castings; but we just park it up in the tunnel out of the way. And when our kitchen timer goes off, why, we'11 either cool it or put in a new casting and press ahead. And I see the - getting some action on the convection experiment over here, on the radial experiment; and we'd be real curious, Gordon, if you can pick this up, if we've got enough light.
CC: Yes, Stu. We can see a difference, particularly on the - as we're looking at it - upper left quad- rant of the radial - window there.
CMP: Okay. Now, as I said before, this quadrangle will heat faster; so, you'11 see more of - a faster color change. Now, these two will also heat, and these are the two that really show our zero-g con- dition, because these two will - and, - are heating out - extended the radial distance out - at the same rate. So, we're not getting any help, on either one of them, from the convection currents. And the fourth one is just now starting to pick up.
CMP: And we'11 drop off from that one and Just let it extend out a little bit; we'11 talk about another experiment we have that also deals with convection.
CC: Roger, Stu. The - That's very apparent that the upper-right and lower-left quadrants are heating equally. That's a very good picture.
CMP: Okay. And we - we did run this experiment on the ground before flight, and it was - It was very marked difference. It's quite impressive how it working - -
CDR: You do understand that the - this quadrant down here is a higher temperature crystal. That's the reason that - that it's not going out as fast as the one in the upper-left quadrant. It has noth- ing to do with the - the gravitational effect at all - it's a higher temperature crystal down here.
CMP: Okay. Now, Gordon, our intrepid LMP is - is hold- ing another experiment. And how's that picture look? Can you get anything of Ed and the blue box here?
CC: We're not getting it, yet. It looks like you're still getting the camera settled down, I'm seeing Ed's face - Now - now we're seeing it - That's right in the center, now. I think, maybe, if you stop the lens down, the - the little window is overexposed with respect to the rest of the scene; so, we've been getting not much more than Just a bright light. That's looking real good, now. I think that's a good setting, right there.
LMP: Okay, Gordon. And what we have here is an elect - electrophoresis experiment. And we're not - we're not going to run this one on the TV camera. It's a one-shot operation. But on the left side here, we're got three channels going across this beauty; and over on the left, in a chamber, we have three different compounds containing organic molecules. And what we're going to do is apply a voltage to each one of these chambers, and then, open up the partition between the chamber where the organic molecules are, and our channel going across. And the theory here being that as you charge the - the molecules, they will move out across this channel. Now, some molecules will take a better charge than the other ones, and they will move faster. Well, under a gravity field - here again, you have the convection currents; and it tends to mix up the molecules; the heavier molecules settle out to the bottom of the channel. They don't make it all the way across, and so forth. All the problems involved with the convection again. So here, hopefully, the only variable will be the different type of mole- cule. And we hope these molecules will then separate themselves in bunches - based on the as- sumption that all molecules of the same kind, you know - you know are all - been doing their physical conditioning and will run as the same rate. So, anyway, the molecules will move across and, hope- fully, will separate them into bands. Now, we've got three different types of - of molecules here; and one, the simplest one, it's Just some red and blue dye. And this phenomena will take place under a gravity field, and this happens on the Earth. And we work up in numbers up to - to quite heavy molecules, and these are the ones that we cannot do on Earth. And we're trying to see if it's pos- sible to - to do them here under zero-g; and there are quite a few ramlfications to this, if it really comes off. And one of the most obvious is in the field of medicine, in making pure vaccines, and so forth. Now, we don't expect this - this experiment to solve the problems. We're trying to get a hack - see if the theory is correct and, also, to work out some of the engineering details, such as, when you heat - apply this voltage, you form a few gas bub- bles around it, and so, we have to have a little pump that circulates the fluid at a very low rate. And we're wanting to see if this works and if it disrupts the travel of the molecules. So, this - this we hope is the first step toward bigger and better experiments and, eventually, a truly manu- facturing process.
CDR: Ed, if you want to move on down closer to that light for a few minutes, we'11 put you on the camera and, maybe, your family can see what you've got hanging all over your face.
CMP: We couldn't talk Ed into shaving this morning.
LMP: Or yesterday morning, either.
CC: You might open up the lens slightly, if you're going to a less brightly lit object.
CMP: Are you - are you trying to say Ed's not very bright, Gordon? (Laughter)
CC: I guess I won't comment on the interpretation there.
CMP: Okay (Laughter).
LMP: I'm being conspired against.
LMP: Since I'm being conspired against, I'11 take the camera back.
CMP: Okay. We'11 come back down off the one that does not deal with - with the convection principle, and that's the transfer of liquid. If I can get out of the way here, and what - is that showing up, Gordon?
CC: That's pretty good - -
LMP: Ail you can see - -
CC: - - for centering, Stu.
LMP: - - is one great eyeball.
CC: Can we - -
LMP: Okay. We're watching it.
CC: That's looking pretty good. You might move the camera down slightly, now. It's in the lower part of the screen. Okay. It's centered; well - it was. Also, you might try a peak on the camera; it might improve the exposure. That was one sugges- tion from the background man there.
LMP: You have peak. How's it now? Peak and f/8.
CC: I think that'11 work. You might open it slightly, Ed. Open the f-stop slightly; and, I think, we'11 have it.
CDR: Okay. What we've got, Gordon, is, of course, two tanks here; and these have no baffles whatsoever. And we tried to transfer the liquid from one, into the other one, and then back again; and we ended up in about the condition that - that you see here, not being able to do much with it. And I've got me a handy-dandy pump, which I'm going to mount on here. And this experiment is, of course, slanted toward the large space station refueling operations, transfer of fluids on a space station - Any time you have a rather large complex structure up here, why, you're going to have to be doing this type operation. And it's a first look at what type of baffles and - we need, and you'11 see this on the other side. What I'd like to show you is a - the difficulty you have when you're trying to do them without any - without the aid of any baffles.
CC: Stu, we see a couple of large bubbles in each tank. Will you point out just which part there is liquid and which part is the air space? Over.
CMP: Okay. The white portion you see is the bubble, and you should be able to see a green fluid around the bubble. Can you see the green?
CC: That's affirmative. We can see where you're - what the parts that you're pointing out there. The colors on our monitor here are not coming in true, but that shouldn't hurt the point of the experiment. Go ahead.
CMP: Okay. We'11 now take - yes - okay. And we'11 - Al's now working this pump, and - okay. We can't even get the bubbles - to change too much, here.
CMP: Okay, and about all we - okay if you'11 watch that. About all you can succeed in doing when you pump with the pump is making the large bubble in the center, and the fluid has a tendency to cling around to the outside edge due to the surface ten- sion. Now, this surface tension is quite important, and that is what will make the baffles work, as you see on the other side. But right now, the only sur- face for the fluid to cling to is right around the edge of the tank; and sure enough, that's where it goes, with the bubble in the center. And makes it very difficult, if not impossible, to work with.
CC: Okay, that's very apparent from the picture we're seeing now.
CMP: Okay, okay. And a little bit of the hardware here, we have a valve up here at the top that connects - connects the two tanks through two - through a tube, here. Now, Ed, if you can get it down. And we've got a valve on each - on the top of each tank here, in which the pump will either pump into this tank or suck from that tank into this tank. The tubing here goes from these valves through a little hand-operated pump. So, that's the engineering be- hind it; and, of course, as you can see, the liquid just clings to the periphery of the - of the tank due to the surface tension. We'11 now switch the tank and show you the operation, using the baffle.
LMP: And while you're switching, I'11 put the camera on Al; and let the world look at him. He did shave this morning. It didn't help a bit.
CC: Roger. We can see that none of you look the worse for - worse for wear on the preceding 3 days' activities.
CDR: No, we feel great up here. Great shape.
CC: Stu, a reminder; if you still have the heat on the radial experiment, you might turn it off. It - it might be overheating by this time.
CDR: Well, you might swing on over. There's another part of the experiment, that we're not sure you'11 be able to see, that we turned on instead. I don't know whether Ed can get it on the camera or not. I'11 push the top in.
CMP: Okay, now, up here, we have the ... we were heat- ing - heating, extending out radially from a point here. Okay, up on the top, we're heating - Stand by 1; here, we'11 get the camera rigged up. Okay, we've now switched to the zone cells, as they're called; and here again, we have the different crystals.
CC: Ed, can you refocus there? As you moved in tight, we lost the focus and lost most of the detail of that part of the experiment.
LMP: How's that, Gordon?
CC: Okay, that's better. I think that range is good. Just hold everything as it is.
LMP: Okay. Okay, Gordon. Now this is essentially the same principle only a different-type heating ar- rangement. Here, we're heating with a band in the center, and we have the crystal in longitudinal strips running out from the center. And you prob - I don't know if you can pick up the color differ- ence or not on these - on these bands as they move out.
CC: We can see - -
CMP: I might add -
CC: - - a little bit of difference there. It's not readily apparent; but, as you point it out, I be- lieve we can see those zones moving out.
CMP: Okay, and that's it basically. Now when we actu- ally do the experiment for data, we have a 16-millimeter camera that sits out i foot; and we turn in on, and it takes a picture, and you go through a sequence here. So it's - it's a detailed experiment, in which we have the procedures and we run through those. And just - what we're doing here is Just showing you the gross features of the experiment and - and its typical operation. Not trying to show you exactly how we gather the data or anything like that. And we're turning off the heat-convection experiment, now.
CMP: Okay, how are we focused on the tanks now, Gordon? Stand by.
CC: Okay, Stu. That looks really good. Just center it up slightly, and we can see the liquid and the baffles very clearly. Over.
CMP: Okay, just to point out that we've got two different-type baffles, I think you probably see the baffle, on this side, and over on this side there are two baffles running up, and with a little different feed-in arrangement - I meant bottom on the - on the baffle. Okay, now, I'11 steady up the camera, and A1 will supply some power on the pumps, and you'11 see the liquid now moving out. And due to the surface tension on the baffles, it clings to the baffles and comes out and fills up the tank in an orderly fashion instead of going up the side walls and leaving that large bubble right in the center.
CC: That's a beautiful demonstration - -
CMP: I know ...
CC: It's very clear from here.
CMP: Okay, good. Okay, we've got Just about all we're going to get out of the tank. Now, A1 will back it up, and we'11 show you how the other set of baffles work. And you'11 note the baffles not only aid on the fluid coming into the tank but also it makes for nice orderly discharge on the other tank. Now you can see it coming into this tank, with here again surface tension on the side walls and the two baffles, and proceeding to fill the tank.
CC: That's very clear, Stu. You might run it back once more.
CMP: Okay, we'11 give it to you again.
CMP: And I don't know if you can see it or not, Gordon; but when a bubble does come into the tank, it's broken up by the - by the baffles and tends to hang in pretty well. There, we just saw one burst there, if you happene_ to notice that.
CC: Hey, we can see that very clearly.
LMP: Why don't you run it fast and show the slosh, if you can get it that fast.
CMP: Okay, we're going to increase the rate of flow on this one.
CMP: Okay, now with the faster flow rate, you don't quite have time for the bubbles to dissipate, using the - using the baffles, and we did pick up a few more bubbles. And, Gordon, you really - you really - to appreciate this, you have to try the other side. I'm afraid that one didn't show up too well, because all we had were the two bubbles in the center; but we can prove to you that the pump was working, because it works on this side. But it - it was just impossible to transfer any fluid after we opened the valve the first time, and got fluid out of one tank into the other one.
CC: I think that's clear, Stu, now that we see how well this side works. We can see that the - without the baffles, it's a pretty hopeless situation.
CMP: Okay, Gordon. That's probably about enough of liquid transfer. And I think we pretty well covered the - the four experiments unless you've got some questions, that I didn't m_ke clear, or that has come up during the presentation.
CC: One quick question. Did you have - Have you tried the - on the heat-flow convection experi- ment - the flow pattern part - part of it where you expected to see Benard cells, did that work out?
CMP: Yes. We tried that, Gordon, and it didn't work out too good. Maybe while we've got the TV here, we'11 - we'11 talk about that one and maybe you can give - get some help, and we'd like to try running it again. We ran everything except the Benard cells. And, Ed, could you put the camera back over on the convection experiment, Ed?
CDR: What has been happening here, in this particular experiment, we have a Krytox fluid that's supposed to come out at three different locations along the base of this cup. Can you see that cup from - from there, Gordo?
CC: Yes. We're getting a very good view of it.
CDR: This is the outline of the cup right here. It has three very small holes down at the base of the cup, at its periphery, and Krytox fluid flows in when we work a little hand pump here. And it's supposed to spread evenly over the bottom of this cup, which it does under one g. The cup is a heating element, and we - we're - we're - we were going to study the rate of growth of the - size of growth of Benard cells in the Krytox fluid. Un- fortunately, we're not sure whether we have air in the fluid, too much air in the fluid, or not; but attempting to get the fluid to flow off the base of the cup through surface tension, we find that we don't have any luck, and rather it comes up along the walls of the cup adjacent to all three of the holes. And if you have any experts down there, we might just talk about that a minute.
CC: Have you tried - -
CMP: Gordon, it ... - -
CC: - - to use an object to move - to try force the fluid to spread on over the surface by opening the lid on it and then trying to force it to spread out evenly.
CMP: You mean physically spreading the Krytox around, Gordon?
CC: That's - that's right. That's the question. We wondered if you tried that yet?
CMP: No. We - we didn't. You know, our instructions there said if it didn't adhere to the - to the surface, we were to close up the lid and go home. We tried it three times; and to amplify there, it comes out of the hole, comes up the wall, and then spreads between the holes right on around the wall and just keeps packing up. We - we're most anxious to try it again; and we'11 - we'11 turn her on, and try spreading it across there.
CC: Okay, Stu. We don't - -
CMP: It, it ... - -
CC: - - intend to ask you to try all this on TV, but our only suggestion would be to maybe open it up and try to spread it across with your finger or with a tissue or something like that. But that seems to be the only idea to be offered.
CMP: Okay. Well, if you've got the time, we'11 - we'11 turn on the Krytox here and - watch - let you watch it come out.
CC: Okay. We're - be glad to watch.
CDR: What I'm doing here is opening a flow valve, between the tank and Krytox and the liquid plate. And over here we have a pump, which is actuated when I turn it in a clockwise direction.
CDR: Perhaps you can already see that we have fluid coming out, right here. It's staying right in this crevice, moving up the side walls. Can you see that on the camera?
CC: Yes, sir. We can see that very clearly.
CDR: See, it's doing it almost the same all the way around it. This one is spreading a little further down the line, doesn't have quite as much fluid yet. But these two are spreading the same way. They're going up the walls as much as they are coming out on the floor. Now we'11 get a finger in here and see what happens.
CDR: I believe we may be able to get enough there to show you the formation of these Benard cells.
CDR: We have a thin layer here, now. Let's turn on some heat and we'11 see what happens.
CC: Ed, a comment for the camera man there - we noticed a real improvement in the picture just about a min- ute or 2 ago. Which - If you did anything differ- ent there, remember what you did for future use.
LMP: We just put it back on average from the peak we had it on a little while ago.
CMP: Yes. We should see some action here probably in a couple of minutes, Gordon, when these - when these form. I think you saw them down at the Cape; didn't you, Gordon?
CC: No. I didn't see those personally.
CMP: Okay. They're pretty impressive, and it breaks into the Benard cell here.
CDR: I think we're having the formation of some small cells; but, of course, the film we've put out here, so far, is fairly thin. It's difficult to get the vertical - vertical circular pattern set up.
CC: Stu, the experts here would like to pass along the fact that it should take longer to get the cell formation with a thin layer of fluid than with a thick wet - than with a thick layer.
CDR: Yes; well, we have a peculiar pattern in this - in this fluid, which you probably can't see; but the fluid, which I put in the center, stayed there, but there's a very thin layer here indicating that it's gone out radially again. And, as you can see, we have some pretty good-size fillets that stay right on the outside of the - of the cup. Very much the same principle as the surface tension that you saw in the experiment of the tank without the baffles.
CDR: Well, the cells are forming. You can see very small cells. But you probably can't pick them up with the camera, because the cells are only ap- proximately a 16th of an inch in diameter, right now. I think - yes - if you hold on Just a min- ute, we're going to see some pretty spectacular formations. They're starting to form right now and get a little bit larger.
LMP: Gordon, are you able to see the detail of the cells?
CC: Not really now, Ed. It's - we see some texture there in the - in the fluid, but it's hard to say that they're really cells from here.
LMP: I think you'11 be able to see them distinctly in a minute. They're starting to get larger and more active.
CC: Okay, now I - Now we're seeing the cells pretty well. They're becoming much more apparent now.
UNKNOWN: Improved common techniques again_
CC: Al, do you recall how many total turns you've put on the knob that pumps the Krytox out? They are curious just what total quantity is in the cup at this time.
CDR: Well, we have about two turns full right now.
CDR: Well, we do have some tiny cells here, and we'11 play with this one some more and photograph it. In the meantime, you all might be thinking about that.
CDR: Well, we can definitely see these - the forma- tion of the same type of cells, although they're smaller than we had down there. Perhaps with more fluid in there, we could get larger cells.
CMP: And, Gordon, after the TV here, we'11 put the camera back up, and take a picture of what we've got here, just while it's there.
CMP: Okay, i guess that's about all of it from our
CDR: I just wanted to say a couple of words before we tonight, that we can, in some way, contribute, through our efforts to the space program, to pro- mote a better understanding of peace throughout the World and help to rectify these situations which still exist. And_rith that thought, for Ed and Stu and myself, I will say good night to you from Apollo 14.
CC: Roger, Apollo 14. Thank you very much for the very interesting and - thank you very much for the whole show. We've enjoyed every minute. Good night.
MCC: "Inspiring" was the word that Gordon was looking for.
CC: The only suggestion we can m_ke on that problem of the Benard cell flow pattern experiment there - is that that rubber surface around the edge of the cup is supposed to be treated so that the fluid won't adhere to it. Obviously, it's not working. The - the only suggestion that might work would be to take a tissue and wipe that off real well and try to clean it as well as possible; and then, try to put as thick a layer as possible of Krytox into the cup with your finger, if necessary, and the thicker the better, evidently, for results - more visible results. And a question for all the experiments. We'd like a status on just where you stand as far as taking data, if - on each of the four. If you could give that to us, the support people would like to know. Also, if you intend to work on it tomorrow, they'11 he here to answer any questions, or whether you're going to finish it all up tonight. Over.
CDR: I - I don't think we'11 be able to get it all com- pleted by tonight, Gordo. However, if you give us a call when they're leaving, then we'11 be able to tell you what the completion factor is.
CC: Okay. Actually, they'11 stand by as long as you wish. So, if you give us just a status right now, I think that's what they want. Have you taken any data on the - -
CDR: Okay, well, as far as - -
CC: - - on the electrophoresis yet, for instance?
CDR: Well, let's start with the metal composites, as far as that's concerned. We have no problems with that, and, well, we have completed, I think, three or four of those, and we will press right on with those all the way in. As far as the heat flow is concerned, we have completed with the zone and the radial flows, and we'11 try one more time on the Krytox. We, I think, only did the film of the fluid transfer. We have no questions on that; so, no further support on that will be required. And we have not made an attempt on the electrophoresis, yet. We're using that for demonstration, for tele- vision only. That's the only one that we would really need any support on at all.
CC: Okay, fine. I think that answers their question.
CDR: We should be getting into the electrophoresis after we finish this next P23.
CC: Okay, thank you, Al.
CMP: Gordon, is anybody concerned about a little longer delay in going into PTC? I was looking ahead at these three constraint stars. We could cut those out if - I'm not suggesting it, but if we're con- cerned about the thermal aspect.
CC: Stand by. We'11 check on that.
CC: Stu, I guess we - we don't see, immediately anyway, any - any particular rush to get into PTC. So, go ahead and complete the P23, as shown; and, if we come up with something, we'11 call you later. That - that - something that requires us to get - get into the PTC sooner; I don't think there's going to be anything, though. Over.
CMP: Okay, I just wanted to check with you. We've been out awhile.
CC: Apollo 14. Apollo 14, Houston. Over.
CC: Okay, tank 3 heater is getting up above the limit. It's 335 and climbing. We'd like to have you turn tank 3 OFF; i and 2 to AUTO. That's the 02 heater.
LMP: Tank number 3 coming OFF; 1 and 2 to AUTO.
CC: Stu, this is Houston. We think we - that you loaded 35, Rasalhague, when you meant to load 33, Antares, there. Over.
CMP: Roger, Gordon. I copy that. Okay. You're so right. I'm seeing double here.
CC: Big Brother is watching.
CMP: Good call.
CC: For Stu, we noticed - at least it looked like it to us here - that he took six marks on star num- ber 5, rather than three on 5 and then three on 6. Probably have to do 6 over. Over.
CMP: Say that again, Gordon?
CC: Well, the backroom guys that were watching said that you did six marks on number 5, rather than three on 5 and three on 6. Is that the way it seemed to you?
CMP: Okay, I'11 do 6.
CDR: He knew 6 was going to be a difficult star, so he was practicing extra on 5.
CMP: Hey, Gordon. The tough one is that number 3. I don't know - I don't know why - that's a tough star.
CC: Yes, we get it.
CC: For EECOM, we noticed one - on the last heater cycle on 02 tank 3, that the temperature went up pretty fast. We'd just like to verify that the 50-WATT HEATER breaker is out. That's on panel 226. The - that's on tank 3.
CDR: You want - 02 tank 3.
CC: Roger. We'd like to know where it was when you look at it. We think it was out; we'd like to verify that, and we'd like you to leave it out, if it is out.
CDR: The breaker was in. It's now out. We're taking a look at our flight plan to see where that was supposed to happen.
CC: Okay, Al. I think it was a real-time readout. It wasn't on my shift, but that's the indication I get right now, that it was a real-time read-up to you for the DTO.
CDR: Okay. We must have missed it, then. Sorry.
CC: Al, we have a fairly lengthy procedure for stowing the probe for entry. We thought it might be a good idea to try to summarize it quickly to you now so that you can think about it somewhat. We're picking out a time tomorrow to accomplish this. We think that it should be no problem to finish it in about an hour, and it looks like maybe the crew exercise period scheduled at 190 hours might be a good time. So what we'd llke to do is get Stu on the horn and summarize the whole procedure. Just quickly so you can think about it, and then when it comes - when you get ready to do it, rather than - probably it would be a long time - take as long to write down all these directions as it would to do the stowage, so we could Just, real-time, read the steps to you one at a time as you accomplish it. And it might be easier than trying to copy it all down. Over.
CDR: Okay, it sounds fine. As a matter of fact, we were discussing that a few minutes ago. If you'11 hold on just a second, we'11 put Stu on the air.
CC: Roger; this is Houston.
CMP: Roger; I think we're all on the air.
CC: Okay, Stu. I'm not intending for you to either write this all down, or to under - to remember it all. We'd just like to give it to you once through quickly so you can think about it, and we'11 do it in detail tomorrow when we get around to doing it for real. The first thing is the stowage for the decontamination bags that ordinarily go on A-10 and A-13. We're going to modify that to stow the one that has 30 pounds in it, and put that one on A-lB, using the existing tiedown rings. But the one that has 20 pounds, rather than putting it on A-10, we want to put it on A-8. And use the D-rings on A-8 in essentially the same manner - the normal manner of strapping it down. On top of that one, we want to take the CMP suit and helmet and put it in a sleeping bag, and then use the LM webbing and lash it down on top of the 20-pound decontamination bag on A-8. And this should all tie down there to allow a minimum 4-inch clearance to the couch for couch stroking. Are you with me so far?
CC: Okay. Now for the probe stowage. We start by going through A-10. And remove anything you think you might need later. We can't identify anything in there that will be needed later, but you want to take a check, because once we get the probe lashed down on top of that - it will be pretty tough to get back in there. Then go to A-5 and remove the headrest pads and put them on the couches. Take the_ heel clips and ropes, there should be five ropes in there, and stow them temporarily. From the right-hand side of A-5, take the cushion and all the equipment that's in that cushion and put it in foodbox B-1. And from A-6, take the two LiOH cans from A-6 and put them in the left-hand side of A-5. So take the TV equipment that's in A-6, wrap the TV monitor in a constant wear garment, and put all the TV equip- ment into B-l, also. Okay. Now take the ropes - take one of the ropes that you removed from A-5 and double it, and then tie it to footpad on A-6 - the footpad that's in the corner. It'd be the plus-Y, plus-Z footpad on A-6. And take three other ropes and tie one end of each of those three ropes - we won't double those ropes - tie one end of each of those three to the same point, that being the other footpad near the wall on A-6. It'd be the plus-Y, minus-Z footpad. Okay. Now we go to the probe and take two flight data file books and tape them to the base end of the probe, the end with the capture latch release handle. The probe now will be placed with one of the pitch arms - those are the large arms that - that normally contact the face of the drogue - one of those pitch arms down toward the aft bulkhead between A-6 and A-10. The apex of the probe pointing in the minus-Y direction and the base end of the probe with the flight data file books taped on them to touching the right-hand equipment bay. Is that clear - more or less the position that it - it'11 be stowed in? Over.
CMP: Yes, it's real clear, Gordon. You're doing a great job.
