Episode Transcript

(00:00):
M the follow eleven that there's dukesand overs. Go ahead, eleven.

(07:12):
You good. In order to improvethe communications a little bit here, we'd
like to try to get you onthe hot game and Canna will recommend me
have the tick dangle of zero they'all three five or five like say again
three five or five the back quick, Manuel and white beam went over.

(07:48):
Okay, ready to quit die game. That's the primitive Yah yah eleven,

(08:16):
Houston, you're inde h Rucker rightout of market rocket uh Roger. We
can talk hip at about eleven.Could you give us a time of dropping

(08:52):
the five ridy and out of fiftythe little rutgers down by about half a
second. Hunf mm hmm. Okay, your time of crossing me one fifty
West Meridian will be seven seven fivezero zero five over. Thank you eleven.

(09:31):
This is Houston. We have aboutsix minutes remaining until LS and in
order that we may configure our groundlines, we'd like to know if you're
still planning to have the TV upat the beginning of the next pass over.

(09:54):
If you get the folks, i'dhave it ready. This is Houston.
We are in firing. If itis your plan to over. Yah,
I never left I plan too.But if then if my plans I
get put it ethan rogrets h mh h h h h h h eleven't

(10:54):
you hm D you go ahead?UH? For you in connection with that
time on the primari and crossing,UH, you have an orbital period now
of two hours eight minutes and thethree seven seconds over thank him not jee

(11:22):
h h h h m m mhmmm. Apollo eleven. This is Houston,

(13:24):
UH, a little over two minutesto l os all your systems parameters
and or we're looking good from theground. We have a OS on the
other side at seventy eight two threeat three one number A right, seventy

(13:46):
eight two three two one, becausethat was three one on the end.
Okay, this is Apollo Control.We've had loss of signal from Apollo eleven

(15:33):
on its first lunar revolution. Wewill acquire the spacecraft UH on the next
revolution at seventy eight hours, twentythree minutes thirty one seconds. The orbital
period for Apollo eleven's present orbit twohours, eight minutes thirty seven seconds.

(16:00):
And as you heard, UH,we passed up to the crew information that
UH we would perform the LOI twoburn using only Bank A. The banks
or the drive mechanisms for the ballvalves in the service propulsion system. They

(16:22):
opened and close these ball valves andthe valves UH allow the fuel and oxidizer
to flow into the flow into theengine their redundant valves and redundant banks Banks
A and B. There was apparentlya l they were driven by nitrogen and

(16:45):
that was the reference to the UHpressure drop. There was an apparently a
leak in nitrogen tank B during theLOI one burn that this UH burn was
performed with both banks open. Theengine can be operated with only one bank.

(17:07):
It It's apparent that the UH thetank leaked only while during the burn
while UH the bank was actuated.Pressure has held steady since UH the end
of the burn, and the expertsare reducing the data and looking at the

(17:33):
leak rate determining whether it was constantthroughout UH the burn, what precisely what
the UH situation is. We're showingUH pressure and tank B of nineteen hundred
and sixty psi in tank A twentytwo fifty psi. Both of these are

(17:56):
well above the red lines of fourhundred pounds be a SI. This is

(19:22):
Apollo Control Houston at seventy seven hoursUH forty eight minutes UH now in to
the flight Apollo eleven here in UHMission Control Center, Houston, UH,
we're in the process of changing shiftsUH Cliff Charlesworth, UH green team of
flight controllers UH very shortly will beleaving their consoles. Meanwhile, Apollo eleven

(19:45):
UH passing UH over the far sideof the Moon out of acquisition our UH
last orbital parameter readings UH on ourUH flight UH dynamics orbital digital displays indicated
UH an aperge of one hundred andsixty eight point five nautical miles UH paralalon
of UH one s UH correction parilonof sixty one point two nautical miles.

(20:11):
We're currently planning a change of shiftbriefing UH at approximately two thirty Central daylight
time or as soon thereafter as ispracticable. The UH change of shift briefing
UH will include only a flight directorCliff Charlesworth. UH. It's expected to
be of short duration since we willUH have a uh TV pass UH soon

(20:38):
after reacquisition of the spacecraft. Atseventy seven hours fifty minutes into the flight
of Apollo eleven, UH. Thisis Apollo controlled Houston. This is Apollow

(21:12):
Control Houston at seventy eight hours UHeighteen minutes now into the flight of Apollo
eleven. Apollo eleven still passing UHthe around the far side of the Moon.
We're UH less than five minutes nowaway from time of acquisition on this

(21:32):
the second revolution UH for Apollo eleven. The station to acquire on this pass
UH will be UH the Goldstone WingSite, UH, which will uh uh
feed uh the television uh UH twoMission Control Center Houston and thence uh to
all parts of the country. Wewould expect uh to UH come up with

(21:57):
television, perhaps some several minutes afteracquisition, since we must first lock up
on the down link and uh uhhave the UH scan converter UH in full
operation. So at seventy eight hoursUH nineteen minutes UH continuing to monitor UH.
This is Apollo controlled Houston School Schoolmark UH two minutes now from time

(24:17):
a predicted acquisition UH in Mission ControlCenter. We are standing by mark one

(25:15):
minute now from time a predicted acquisitionthat continueing to stand by and Mission Control
Center Houston mark cut ten seconds awaynow standing by for acquisition. UH.

(26:30):
We've we've had aos, uh bigoldstonehelp television is uh now on Uh that's
Bruce mccanni's ark help allow eleven ifyou're here to Howard and a bottom eleven,

(27:03):
I pick it up, okay,A follow eleven. This is Houston
Affirmative. We're reading you loud andclear on voice, and we have a
good clear TV picture. A littlebright crater and me, I don't know
that is the bottom of a picture. I guess that's the spot on the
tube. That's all right, talent, and I think could give us pooh

(27:27):
and accept. We'll uplink a newstage victor and target load to you.
Okay, okay hm uh it's beenabout eleven uh one of the marker uh

(28:26):
craters on the backside right out tosay, uh small dark backs on the
uh the outer wall, and Iput a uh an occupant on it.
I was able to see uh overan area maybe uh or a quarter of
a mile in diameter of a uhearly fresh looking uh dark colored tit uh

(28:52):
that seems to be in contrast withall the other uh fresh uh little crater
at a hole that you can't perceiveit on on the walls. Any of
these players uh around the one theuh to agree on the best one that
caught my attends remarkable of them,Roger, do you have a location on

(29:18):
that one and not a right?Are we copy that was buzz alder and
making a report, uh, geologicalreport on the back side pass. We're

(29:41):
getting a beautiful picture in down herenow eleven the colors coming in quite clearly,
and uh we can see the horizonand the relative blackness of space.
And without getting into the question ofsome grays and browns, it looks,
at least on our monitor, sortof a brownish gray. I think uh

(30:04):
uh way of the trident. Uhit appears to me is though, Uh
it made it different just sitting backin the uh in the tunnel and gazing
at all windows, it makes adifference which one you're looking out of.
Uh. For example, Uh acamera right now is looking out the uh
uh number five window and uh itdefinitely gives a rosier uh or panned tinge,

(30:32):
especially uh when you look straight shotand not uh not had an angle
of it. H rider, shecan't safe flight? Hey where about her
ninety five or a hundred degrees?Agent going up? I client se still
holding Okay, uh so again Ilove it. I think you about ninety

(31:00):
five degrees e's coming up onto mySea Roger and for your information, we
show you at an altitude of aboutin ninety two miles above the surface.
Right now, Okay, it's beena bottle. I mean, did you
observe a difference than the and twopressures before lay? It seems to me

(31:23):
as though two were not equal inthe sand by Hale, the tank was
a low pressure of it. Yeah, I think that's right. Uh.

(31:48):
I'm buying it at SDS minimum impulseUS and it's rather difficult to keep it
on a constant data. The lembwants to wander up and down. I'm
not sure in response to mask onor what. But I can get it
completely stabilized in data and let italone and in another couple of minutes it

(32:12):
will have developed its own rate.This is Houston Roger. That was Mike
Cullins making their report, and we'llbe moving shortly from the sign window to
the hatch window and we'll kind ofpick up some of the landmarks that will

(32:34):
be looking ash as we approach thepower Team eleven. This is Houston Roger
and we're through with the uplink computeras yours. You can go to block
and we'll have the information on nitrogenfor you shortly over. Got the copy.

(33:00):
Hey, here's been uh several minutesago, I was exactly steady on
data and then I have been movingtoward the limb pointed straight down towards the
radio spector, and that's been despitea number of down minimum to typo Ruggers

(33:40):
where over it might see right now, Rogers, we're about eighty eight degrees
these that would have to name.But we'll show you about south of the
southwest of the crater Janski right nowmight see doesn't like very much like to

(34:22):
see. And uh, the areawhich is devoid of craters, which is
not very much is sort of ahilly looking area. It's not like a
Maria at all. ROGERI copied thatabout the sea and it looks like you're
just giving us a view of thecrater Naper a large crater on the left
and Janski on the right. Thatexchange between Cap Tom Bruce McCandless and Mike

(34:47):
Collins aboord the Apollo eleven spacecraft,we think, but not the guard Apollo

(35:44):
control of Houston. We acquired TVat seventy eight hours, uh twenty four
minutes, eleven seconds. Uh.Currently uh, our orbital parameters show uh
one oh four out to to anapplelloon of one seventy point two a paarloon
of sixty one point three nautical miles. So sorry, well is hereston?

(36:13):
Would you care to comment on someof these creators as we go by Roger
for approaching the approach path to ignitionas this equivalent to thirteen minutes before ignitian,

(36:37):
and we're at about eighty degree beasI guess eighty three degree bets that
correspond to location. Your holy dadrighter, we're showing your present position is
about seventy seven seventy six degrees eastlooking back towards the east. Hey,

(37:07):
you could be looking back at mykena alright. Uh, we've now heard
from all three Apollo eleven crew membersduring this television pass. Uh. The
individual talking earlier was uh Neil Armstrongor Schubert and uh Gilbert, you is
uh in the matter right now?And it comes up at about uh a

(37:31):
little over twelve minute for uh powerdeep and we instead of be looking instead
of looking back at it, we'dbe looking straight down at it at that
time. Uh. Uh well,show you an altitude now of about a
hundred and ten miles, and ofcourse you'd be considerably lower the initiation of

(37:52):
power decent. H Okay, it'sthen look at registeredry and the DISKY beta

(38:12):
data is increasing toward my desire topresusteen and I left the hand controller along
here, and I'll bet you reversesitself. Roger eleven. We're watching the

(38:38):
disky now and still coming in beautifullyon the TV. Okay, there's the
right side of the screen at thepresent time. There's a triple crater with
with a uh ball crater between thefirst and second, and the one at

(39:01):
the bottom of the screen is schubertY boom in. It does have a
central peak in chubrit Y, actuallyseveral of them that you can observe those,
but the rem graders at the bottomof your screen. Roger, we're

(39:27):
seeing the central peak quite clearly now. Okay, we're zooming in now on
pray. They're called schubert In.Schubert In very conical inside well, and

(39:57):
the bottom of yours to be nearlyplat. Look at data on the discy.
It's stabilized and uh it's holding steadynow, Rogers looking out the window,
I can see a number of allcreators on the bottom of super den

(40:22):
for coming up on the bombing.See where I'll be doing some B twenty
two marking on a creator of mychoice name of Crater Camp. Right.
Sorry, we'll be watching for Camps. And notice Register three has reversed itself
and it's heading back the other waynow without any pitch doctor buying Roger,

(40:46):
Mike, we confirm that you've changedthe direction of your pitch rate. M

(41:17):
generally thinking the entity seems to beto put a limb down to it,
uh the center of the moon,as in the gravity gradient experiment Roighter eleven
week. Coppery may have to dowith mas kinds. There may all righter
we've got may have something to dowith math kinds. There may just be

(41:39):
the peculiarity of the disky display.Okay, we've observed the behavior of your
diskey, and I think we've gotthe data here to work on it.
Uh. Let us grind around alittle while on it, and we'll report
back to you. They're probably ina reverende Okay, Well, in the
meantime, I'm going to pitch downtoward three fifteen. Roger h Three craters,

(42:15):
three horizontal crators that now have inthe field of you are immediately underneath
the ground track the right and thelargest crater that you'd see of Gibiago p

(42:37):
Roger. We can occur on theidentification of the crater. We show you're
coming up on landmark Alpha one here, Charlie Roger, Mike Han his first

(43:02):
look at Alpha one at the presenttime. Yeah, it's a great bright
crader. It's not a larger andvern extremely bright one. It looks like
a very recent and I would getthe impact crater with ray streaming out in

(43:22):
all directions, which should make mystory correction the foaming See easy to be
coming up on it now. Playcamp is one of the followings out on
the on the floor of the FoamingSee. We've been some seventeen minutes snow

(43:55):
into this television pass a stand hemight continuing to monitor. Here. We

(44:23):
show you uh over the sea offertility now and UH ort to have a
langress uh down the south of tracka few degrees about uh nine degrees south
attract. Yeah. The grater that'sin the center of the screen now is
uh web Uh. We'd be lookingstraight down on it at about six minutes

(44:45):
before power decent. It UH hasa relatively flat bottom UH to the crater,
and you can see maybe UH twoor three UH craters that are in
the bottom of it. On theUH western wall, the wall that's now
near to the UH camera, nearthe bottom of the stain, we can

(45:07):
see h a temple prayer that donethe outside and then coming back toward the
bottom of the stain. And tothe left you can see H a series
of depressions UH the type of UHconnected craters that give us most ut the

(45:29):
discover why they're in the particular patternsthat they're in. Assume the camera in
and try and give you a littlecloser look at this roger. We're observing
the temple crater. Now, UH. The central peak we can see on
the orbit of photos doesn't seem tostand out very well here, Well,

(45:51):
they're at central peak. They're depressionsin the center you know that is in
the It's such activity. I stilli put in a dozen minimum impulses and
pitched down and I'm still far fromcorrecting back three fifteen moving the camera over
to the right window and how togive you language. UH, it's several

(46:15):
central peaks and Roger. We've gotLangeriness in our screen. Now, hey,

(46:43):
well, then this is Houston.Uh we're getting a beautiful picture of
Langreness now with its rather conspicuous centralpeak. See of fertility doesn't look very
fertile to me. I don't knowwhose name is. It may have been
named by the gentleman who Investraator wasnamed after langer I. Slangeress was a

(47:08):
cartographer king of Spain and made oneof the one of the early reasonably accurate
maps of Little Rod. I'll havebetter for our purposes than the Sea of

(47:32):
krat Okay, it looks like you'recoming inside now on the camera. Well,
I can't get behind to see themonitor. I'll bring a focus.
But we're going to be looking downat one of the lamb quads and one

(47:55):
of the antennas, almost straight downat the ground in tractive book been coming
in. I get this maybe threeminutes four decent? All right, that's

(48:25):
you put the lamb instructure about infocus. I'm gonna uh move it out
to Montanity and then uh expand thefield of view. Prayer Teche is out

(48:49):
my window now window number two stopfollowing a welles of the Houston they show
you coming up on the terminator atseventy eight fifty three, about seven minutes
from now. And we've also gotthe l I two and TI five pads

(49:12):
ready for you after the TV wheneveryou want to terminate over feel us.
Okay, And we're getting a goodview of the track leading into the landing
site. Now, okay, itlooks like we've got sechi ko. Why

(49:49):
about that ten seconds ago coming upon a fallow ridge h M. And

(50:23):
then the right hand portion of ourscreen right now we can see messier Alpha
and Bravo with the light colored raysstreaming off in one direction. M.

(50:49):
I don't know if you make appbut in the s of fertility there are
a number of craters, craters thatare just barely discernible, old old craters.
The outlines are just barely able tobe seen. Luger, I think
we can make them out. Thecolor really enhances our ability to discern features
and craters over what we be inreal time on our black and white monitor.

(51:17):
Right at these lost sun angles,there's no trade of brown and now
returned to a very gray appearance.And like the ATREUS says, it has
a look of plaster of Paris toit at the sun angle, which completely
lacking at a higher sun angles.Roger, we're now some twenty five minutes

(51:44):
into our television test. Okay,this is a right parts technician point for
parat fans. Just passing Mount Marylandat a triangular shaved mountain that you see

(52:05):
in the center of the screen atthe present time. With the creator Secta
on top of the barn Ruthern edgeof Idure, we're getting a good view
of Mount Maryland. I know,Seck you said him. And now we're

(52:32):
looking at what we call Boothill Curristwenty seconds into the defense watching this pass
with a great deal of interest.In Mission control center is Pete Conrad,

(52:55):
the commander for the Apollo twelve mission. Right edge of the cream Senserina Ta
now passing uh at one minute pointin right here, and for your information,

(53:17):
your current altitude is one hundred andforty eight nautical miles above the surface.
I'm unable to determine altitude at all. I can have to win too.
I couldn't del it her down atsixty year up at twenty seventy.

(53:37):
I'll let you get tell if youwere down at fifty thousand and six.
I went to deep are passing somesteep bridges here the edges of all traders

(54:04):
that were photographed by Apollo Pan andthe crew of Pollokan was very impressed with
the steep us of these rages whenthey came over them at about fifty thousand
set. So, Roger, wecan observer there also, Steve. Even

(54:25):
from this altitude, you've got quitea shadow being gassed with the sun see
below angels. The entire surface ofgetting considerably darker than the service that we
looked at previously when the sun wasquite high above us. The crater and

(54:49):
the right crater in the center ofthe screen the smaller when his sins arena.
Roger, well show you a littleover one minute from the terminator at
the prost time. How's the brightnessof the picture you're receiving an open up

(55:15):
the top coming west. Come yeah, the Beau. The brightness is still
doing quite well. You can goahead and open it up a stop her
to the automatic light level compensation seemsto be working beautifully. H has a

(55:45):
good picture of food Hills Uh intothe defense reader worth seeing Boo Hill.
Now I'm the next creator coming andthe bottom that the island right there and
to the left the crater. Thelargest of the crater near the center of

(56:07):
the picture right now is Mascaline W. This is a position check during descent
at about three minutes and thirty nineseconds, and it's our down range position
check and cross range position check priorto ying over space up to acquire the

(56:28):
landing radar. At this point wewould be unable to see the surface below
us until getting very near the landingarea. Roger, I am a.
They get a real good look atthat tomorrow afternoon in US reel as the

(57:01):
one that was referred to in amallow tan as sidewinders, good name too,
side winded diamondback with like a coupleof snakes down there in the lake.
Bit And we're aproaching the terminator now, and see the rodger ass increase,

(57:36):
and only the sunlit side of thebridges uh remain eliminated, while the
dark sides in the shadow will becomecompletely black. Eleven. This is Houston.
The picture is getting a little grainynow. You might go ahead and
open up the f stop m landingpoint is just barely in the darkness.

(58:07):
That what crater is, the upperpart of which you see lower part completely
in darkness, is small. Well, the ninth crater is bulky, which
is about a beam of landing thing. Roger, we can just see it
looks like a little less than halfof its rim right now, and we

(58:30):
can make out just barely some featureson the surface, maybe from Earth.
Tick. Are you wide open onthe f stop of the sun where we
are, Yeah, it looks likewe're just about to get the sun coming

(58:54):
into the line. So that's themovie camera line. Roger can't say any
airs showing or any surface features atall. And there's showing now due to
the fact that the limb is verybright and is causing our pupils to contect.
That's very fantastic gives to the dominatoras you look along the edge of

(59:15):
it. I think you'll agree thatsome of these figures that you're being in
a picture now are really accentuated bythe lengthening of the shadows as an approach
the terminator. Yes, that's avery beautiful and rugged site that we've got
on the screen. Now. Ithink you've got some interesting data ontructor firings

(59:40):
versus bit tangle. It looks likethat lamb just wants to head down toward
the surfaces. All Roger I havea comment here says that's what the limb
was built for. I believe,and as the moon think slowly in the

(01:00:32):
west. Apollo eleven did a goodday to you, all right? Did
we sorry about it? With UHsun fitting in the heath. There you
have it, UH, our firstglimpse of the lunar surface drain the Apollo
eleven mission. UH. The elevencrew took us on a UH guided tour
of the front side. UH plustalk their way through UH the power descent

(01:00:54):
that lies ahead in tomorrow's activities.At seventy eight hours fifty eight minutes into
the flight of Apollo eleven. Thisis Apollo controlled Houston, continuing the monitor.
