CAPCOM 11, we’re really amazed at the quality
of the picture up in the tunnel.
It’s really superb.
Over.
SC Hey, we’re about to open our hatch now.
CAPCOM Rog.
PAO Buzz Aldrin reporting that he’s halfway
into the LM.
His view is inside the LM cabin.
CAPCOM Hey, that’s a great shot right there.
We see you in there.
Guess that’s just Neil and Mike.
Better be anyway.
CAPCOM We see you waving.
PAO Aldrin has apparently carried the camera
into the LM with him and showing us Neil Armstrong
and Mike Collins back in the CSM.
CAPCOM Hello, Apollo11, Houston.
We’re standing by to watch your set up on
the PTC at any time.
You can start off at the VERB 49.
Over.
SC Wilco.
We’re just finishing up the probe and about
to close up the hatch here.
We’re going to be a couple minutes late
probably starting on the PTC.
CAPCOM Roger, no sweat, 11.
We’re standing by.
Over.
PAO This is Apollo Control.
That was Nell Armstrong reporting that they
are now reinstalling the probe and drogue,
which is Just about on the flight plan schedule,
and they reported that they would be putting
the spacecraft in a slow roll shortly to maintain
passive thermal control.
In that mode the spacecraft rotates at the
rate of about 3 revolutions per hour to maintain
even heating.
We have a precise time on that sphere of influence
change, the point of which the moon - for
calculation purposes here.
Mission Control, comes under the predominate
influence – the spacecraft comes under the
predominate influence of the moon's gravitational
field, and we now calculate that that will
occur at 61 hours, 39 minutes, 55 seconds,
ground elapsed time.
CAPCOM Hello, Apollo 11, Houston.
Mike, there's no wait required where REG's
are steady you can proceed on.
Over.
SC I'm doing it, Charlie.
CAPCOM Roger.
SC The tunnel's all taken care of and drogue,
probe and hatch are all back in.
CAPCOM Roger.
Copy · Out.
CAPCOM Hello, Apollo 11, Houston.
We have some new additions to your alternate
contingency checklist, if you would break
that out.
Over.
SC Stand by.
SC Okay, Houston.
It’s ready to copy.
CAPCOM Roger, 11.
If you'll turn to page F/2-22.
Over.
SC Okay, I have F/2-22.
CAPCOM Roger, Nell.
Under column L - that's column Lema, line
06.
The new data is 00001.
Line 07, the new data is 02134.
Over.
SC Okay, I have in F/2-22, column Lema, item
6, 00001.
Item 7, 02134.
CAPCOM Roger, that's correct.
Thank you much.
Out.
CAPCOM 11, Houston.
For your information, those 2 entries are
an update to your Delta-H that we have already
uplinked into the CMC.
Over.
SC Roger.
Thank you.
SC Well, what was I marking on, Charlie, about
an 18 parameter line or what?
CAPCOM Our update puts you to the Delta-H
to 35 parameters, Mike.
Over.
SC Okay.
CAPCOM Hello Apollo 11, Houston.
We've got some switch positions for you for
the high gain, over.
SC Okay, go ahead.
CAPCOM Roger, Buzz.
Select BRAVO, OMNI, high-gain track to manual
beam wide, over.
SC Okay, Bravo, OMNI track manual and beam
Y.
CAPCOM Roger, and your high-gain angles are
minus 50 on the pitch, 270 on the yaw, over.
SC Okay, going there now.
CAPCOM We have some updates and some things
we'd like to talk to you about, if you aren't
in the middle of your meal.
If it's convenient any time for you, we're
ready with some updates.
Over.
SC What are the updates going to apply to?
CAPCOM Roger.
We have a couple of changes on the LM mission
rules NO/GO for your NO/GO card, Neil.
One slight change on the APS DPS fuel and
temp pressure
cards, and we have a change to the procedure
for the secondary radiator leak check, which
is to be formed at - performed at 71 hours
tomorrow, and also some indications that we
have a couple of landing site obliques stowed
in the wrong place.
Over.
SC Okay, if any of those in the flight plan.
The secondary radiator, for example.
CAPCOM That's affirmative.
The secondary radiator leak check is called
out in the flight plan at 71:20.
That procedure is listed in your launch operations
book on page 2-9, L2-9.
We'd like to change that procedure.
Over.
SC Okay.
Stand by.
SC Charlie, on the secondary leak check, just
read us verbatim like you want, and I'll copy
directly into the flight plan and not fool
around with the checklist.
CAPCOM Roger.
That's fine if you're ready to copy, stand
by.
SC Ready to copy on the leak check.
CAPCOM Roger.
It's monitor the secondary accumulator quantity.
Step 2 is secondary glycol to radiator valve
normal for 30 seconds then bypass.
If no decrease in
secondary accumulator quantity, - Are you
with me?
SC Yah, I'm with you.
CAPCOM Okay.
If no decrease in secondary accumulator quantity.
Secondary glycol to radiator valve to normal.
Next step, secondary coolant loop pump AC1
or AC2.
After 3 minutes, verify glycol discharge secondary
pressure 39 to 51 psig.
Also verify secondary EVAP APS TEMP has changed.
Next step, secondary coolant loop pump, off.
Secondary glycol radiator valve to bypass.
That ends the procedure.
Over.
SC Okay.
I read back monitor secondary accumulator
quantity, secondary glycol radiator valve,
normal for 30 seconds then to bypass.
If no decrease in secondary accumulator quantity,
secondary glycol to radiator valve to normal.
Secondary coolant loop pump AC1 or 2.
After 3 minutes, verify glycol secondary discharge
pressure 39 to 51 psig.
Verify secondary evaporator outlet temp has
changed.
Secondary coolant
loop, off.
Secondary glycol radiator valve to bypass.
And what's the reason for the change, Charlie?
CAPCOM Roger.
Stan is concerned that our present procedure
as shown in the checklist does not really
flow a glycol through the radiator and they
want to
verify that we do not have a plugged secondary
radiator.
Over.
SC Okay.
They didn't have any abnormal indications
in that system, so far?
CAPCOM Negative.
This is the procedure that came up with.
It's just a check, Mike.
Everything's looking great to us.
Over.
SC Okay, Charlie.
SC Charlie, we'll get back with you on these
other changes in a few minutes.
Okay?
CAPCOM Roger, Nell.
No hurry.
Over.
PAO This is Apollo Control at 59 hours, 9
minutes.
Apollo 11 now 182 000 nautical miles from
Earth, and the velocity down to 3072 feet
per second.
We've had
very little conversation from the spacecraft
in the past 40 minutes or so.
At this time the flight plan calls for the
crew to be getting ready to begin their eat
period.
That would be followed by a 9 hour rest period.
We have one change to the flight plan to pass
along.
The television transmission which had been
scheduled at 100 hours, 20 minutes to I00
hours, 50 minutes in the flight plan has been
deleted.
This transmission was to have occurred during
the formation flying prior to the powered
descent to the lunar surface.
The decision to delete the TV transmission
from the flight plan was made due to a lack
of available satellite channels to relay the
signal from the tracking site at Madrid to
Houston for conversion.
The intermittent music that we're getting
is apparently coming
from the spacecraft.
The crew has onboard portable tape recorders
with music on the tapes.
As they store their own comments on the tape,
the music, of course, is erased and apparently
the music is triggering the VOX operated microphones
and we're getting intermittent music down
from the spacecraft.
CAPCOM 11, Houston.
We were wondering who's on horns?
SC Back in Houston?
CAPCOM We just had a little music there.
SC Just to keep you entertained.
CAPCOM Rog.
That was good.
You can keep it coming down, 11.
SC Okay.
SC Because it's a special occasion today,
Houston.
This is the third anniversary of Gemini 10.
CAPCOM Roger.
Happy anniversary.
SC Stay there.
PAO This is Apollo Control.
That comment a moment ago about the tenth
anniversary of - about the third anniversary
of Gemini 10 came from Mike Collins, who along
with John Young flew the Gemini 10 mission,
July 18 through July 21, 1966.
PAO This is Apollo Control.
That comment a moment ago about the tenth
anniversary of - about the third anniversary
of Gemini 10 came from Mike Collins, who along
with John Young flew the Gemini 10 mission,
July 18 through July 21, 1966.
The brief bit of music that we got from the
spacecraft was coming to us from a distance
of 182 thousand 190 nautical miles.
SC Houston, Apollo 11, ready to copy your
updates.
CAPCOM Roger, stand by.
CAPCOM Okay Buzz, the first item, is that
we have indications that your landing sight
obliques are not in the proper position.
If you will check we think that the intermediate
scale landing sight oblique is stowed in the
CSM lunar land mark book.
We think that the large scale, landing sight
oblique is stowed in the back of the LM lunar
surface map book, over.
SC I think I heard you Charlie, but I'm not
sure that I understand.
CAPCOM Roger, according to our storage list
the landing sight oblique should be in the
transfer bag.
In the back up set of data, the intermediate
scale oblique is in the CSM lunar landmark
book and the large scale oblique is in the
back of the LM lunar surface map book, and
that's the reason we think that they might
be, not where you think they
are, over.
SC Okay, we've got three obliques.
The last one is one I asked for recently.
It's just a blow up of the second one.
The first one is one that's got dotted lines
on
it, indicating hidden view and 50 degree LPD,
and all three of those are in the transfer
book, over.
CAPCOM Roger, fine.
We were wrong in our back up set.
We had those out of place.
Looks like the on board data is good.
We just wanted to let you check on that one.
We have an update on the APS DIPS fuel cord
that you place on the panel.
It's a typo error.
If you'll break out that little card, we've
got to correct that typo error, over.
SC Rog.
SC Okay, I got it.
CAPCOM Rog, Buzz.
Under the DIPS column, on the pressure side.
You go down to the fourth item to the pressure
greater than 150 PTCA should be greater than
65 percent, over.
SC Okay, it's greater than 1.8 but less than
65 and greater than 150 for greater than 65.
CAPCOM That's affirmative.
Out.
CAPCOM And we have three items on the mission
rules no go card, if you are ready to copy
those, over.
SC Okay, I've got the mission rules no go.
CAPCOM Roger, Buzz.
First entry is on the EPS, under AC bus A.
The line extends all the way to high gate.
Actually, the line should read at DOI it would
be no go
AC bus A. After that the no go would be both
buses.
So if you will just pencil in both buses from
TDI through high gate.
It will be correct for that line, over.
SC Okay, I got that AC buss A for DOI and
both busses no go for PDI on.
CAPCOM That's affirmative up until high gate.
You can stop at - the line in front of the
column 5 minutes to low gate.
Now the next line is under the G&C exchange,
pitch and roll GDA.
You can scratch that line completely, over.
SC Roger, got it.
CAPCOM Okay, Buzz.
Last entry is down under RCS and it is a typo
error under the three - in the line three
axis attitude control.
We proceed to the right at PDI plus 05 you'll
see one axis.
The line goes all the way to low gate to touchdown.
That's incorrect.
The line should stop under 5 minutes to low
gate, over.
SC Okay, we are stopping at it 5 minutes to
low gate.
CAPCOM That's affirm.
That completes that card.
The rest of the update are just really for
your information based on our 58 hour platform
- look at the platform.
We are
really in good shape.
Your gyros have almost no drift in them since
the plotted update we were looking at X of
a minus 2.24 MERU, Y of plus .87 Z of minus
.11.
Since the update, which was based on the 52
hour P52, I believe.
We gave you
an X drift of plus .79, yaw of plus 1.06,
Z of plus .02 MERU.
The difference we see between the 52 hour
and the 57 hour alignments work did not really
give us enough time to get a real good, completely
valid update on the drift check.
So we're real satisfied with the way the gyros
are looking.
The PIPA'S are looking great
also.
We are in real good shape with those also,
over.
SC This is Apollo 11, radio check.
CAPCOM Roger, reading you fly by OMNI, over.
SC Okay, that’s clear.
You cut out when you were talking about the
platform at something about 52 hours and.after
that we never heard you again.
CAPCOM Roger, guess we were changing antennas.
Stand by.
That's affirmative, 11.
We were swapping antennas on you down here.
Basically the word here is that we have a
real good platform, very small drift on the
gyros and very small drift in our PIPA'S,
over.
SC Roger, thank you.
And I would like to have a few words of clarification
if you will give them to me on the RCS reel,
what that change of pitch may mean.
CAPCOM Copy, a few words of clarification
on the RCS, oh roger.
The update there, Neil, you are speaking of
about the one axis down to 5 minutes of low
gate?
SC Yah, that's right.
I'm not quite sure what that really means
(garbled).
CAPCOM Standby, I'll make sure I got my story
straight with Control.
Standby.
SC Okay .
CAPCOM 11, Houston.
On the RCS, what we about one axis prior to
low gate, we would recommend an abort.
This would require a- a loss of - of two distinct
jets which is not very probable but that is
what we are recommending.
After low gate we would - continue on.
We would recommend that we continue on to
attempt a landing, over.
SC Roger.
Okay.
I think I owed him that.
CAPCO Rog.
SC Charlie, did you say you had some updates
for me from the lunar surface book?
CAPCOM Apollo 11, say again.
You were cutting out.
Over.
SC Roger.
Did you say you had some updates for us in
the lunar surface book?
Over.
CAPCOM Negative.
At this time, we do not have any updates for
the lunar surface book.
We wanted you to have it just in case.
Over.
SC Rog.
You were cut out that time.
CAPCOM Roger.
At the present time, we do not have any updates
for you on the lunar surface book.
We are thinking about some, and kick him around,
but they're
very minor changes.
Over.
CAPCOM I1, Houston.
Did you copy that transmission?
CAPCOM Apollo ll, Houston.
We swapped antennas on you again.
I say again that we do not have any lunar
surface update - book updates at this time.
We're considering a few minor ones, but we're
... around 
the MOCR.
Over.
SC Apollo 11.
I understand.
SC Houston, 11.
We have a crew status report for you.
CAPCOM Roger.
Go ahead, 11.
SC Okay, radiation CDR 11009, CMP 10010, LMP
09011.
No medication.
CAPCOM Roger, 11.
We copy for the radiations and we're considering
this PTC looks sort of weird to us so we're
considering stopping and starting over
again and we'll be with you in a couple of
minutes.
Over.
SC Okay.
CAPCOM Apollo 11, Houston.
Would you give us the LM CM Delta-P as reading?
Over.
CAPCOM Hello Apollo i1, Houston.
We switched the antennas on you again.
Would you please give us the LM CM Delta-P
reading?
Over.
CAPCOM Hello Apollo 11, Houston.
Over.
SC Go ahead.
11 here.
CAPCOM Rog.
We switched antennas on you there moments
ago, Neil.
Will you please give us the LM CM Delta-P
reading?
Over.
SC It's less than 21.
CAPCOM Roger.
SC 21.5 now Neil says, Charlie.
CAPCOM Roger, thank you Mike, could you give
us some help?
This PTC is strange, it's not like anything
we've seen before.
We were wondering if you all have had any
events of any odd data that could help us
out, over.
SC I didn't understand that.
Say again.
CAPCOM Roger, we're looking at a, sort of
a funny looking PTC.
We've already drifted out to 70 degrees in
pitch and we're wondering if you all had any
vents or any
such thing as that, that could have caused
us to pick up these rates to drive us off,
over.
SC Negative, Charlie.
We don't know of anything.
CAP COM Roger.
SC Unless it’s got something to do with
that entry from the position that we want
to be in.
I don't know.
CAPCOM Roger, when we started off it looked
real fine to us, now it's drifting off with
a funny pattern that we haven't seen previously
on a flight, and we're just trying to figure
out, I think we'll probably start it over
again.
We'll be with you momentarily, over.
SC Okay.
CAPCOM Apollo 11, Houston.
We hate to say it, but we'd like to terminate
this PTC and start over again.
We bare no assurance that we're going to get
it through the
sleep period.
With this funny configuration, or funny pattern.
We'd like you to stop it now and go back to
pitch 090 yaw 0 and roll, whatever you stop
on, over.
SC Roger.
PAO This is Apollo Control at 59 hours 57
minutes.
A few moments ago you heard Capcom Charlie
Duke advise the crew to terminate the passive
thermal control
mode that they are presently in and reestablish
the three revolutions per hour roll rate about
the spacecraft longitudinal axis that is used
for thermal control.
We had noticed a
unexplained deviation from the attitude that
the spacecraft was set up in.
In this roll mode ideally it would roll about
the longitudinal axis with very little wobble
and if wobble
is introduced for one reason or another, the
reaction control system jets would come on
as soon as the motion out of the prescribed
plane had occurred and gone beyond prescribed
limits, in this case 30 degrees to correct.
The jet firings on past missions do tend to
disturb the crew’s sleep.
Rather than have the reaction control system
jets come on during the night and perhaps
have to awaken the crew to reestablish the
passive thermal control mode at that time
we elected to correct it now.
CAPCOM You disabled Bravo and Charlie select
quads ALPHA and DELTA, over.
CAPCOM Apollo 11, Houston, over.
PAO This is Apollo Control.
We're getting quite a bit of noise on the
air to ground circuit at this time as the
spacecraft rotates from one OMNI antenna around
to the next and we momentarily- lose lock-on.
At this time, Apollo i1 is 183,544 nautical
miles from Earth and the velocity, holding
fairly constant now, at about 3042 feet per
second.
It's been moving down towards 3000 feet per
second and seems to be leveling off somewhat.
PAO This is Apollo Control.
We're going to take the air to ground circuit
down temporarily until a stronger antenna
lock is - . Here's a call to the crew.
We'll stand by for that.
PAO This is Apollo Control.
We will take down the air to ground circuit
down at this time until we reestablish sufficient
signal strength to eliminate the noise on
the circuit.
PAO This is Apollo Control at 60 hours, 10
minutes.
We've reestablished good antenna lock-on this
time, and we'll continue to monitor for any
conversation from
the spacecraft.
The crew is presently reestablishing the passive
thermal control rotation rate of 3 revolutions
per hour.
Following that we expect they will begin their
rest period.
At the present time Apollo I1 is 183 821 nautical
miles from Earth at a velocity 3037 feet per
second.
CAPCOM Hello, Apollo 11.
Hello, Apollo 11.
Over
SC Hello, Houston.
You call us?
CAPCOM Roger.
Reading you about 1 by.
Looks like we picked a super attitude here
for PTC stabilization.
We're reading you in backup voice now.
Over.
SC You're reading me loud and clear?
CAPCOM Rog.
SC Would you like us to take another antenna?
CAPCOM I think we've got about the best configuration.
We have been doing it off the ground here,
11.
We'll just keep it as it is.
Over.
SC Roger.
CAPCOM Apollo 11, Houston.
Would you select COMMAND RESET and OMNI ALPHA?
Over.
SC Houston, 11.
We're in OMNI ALPHA.
CAPCOM Roger.
We read you about 3 by now.
Over.
SC Roger.
CAPCOM Apollo 11, Houston.
We is stable.
You can start the PTC.
Over.
SC Roll left, don't you?
SC Houston, Apollo 11.
Check this page S-9-7.
I've completed step 8 and I'd like to know
what you think is ideal timing between step
8 and step 9 and step 10 on that page?
Over.
CAPCOM Roger.
Stand by.
CAPCOM Apollo 11, Houston.
We don't see any time constraint.
We'd like you to go ahead and set up the wide
deadband, then go through step 10 and 11.
Over.
SC Okay.
Will do.
I don't see any constraint here, Charlie.
I was just checking to make sure because last
time, I went from 8 to 9 to 10 to 11 a little
bit more swiftly than I'd been doing in the
past.
CAPC0M Roger.
SC Step 11 complete.
CAPCOM Roger.
We copy.
CAPCOM Apollo 11, Houston.
Would you please select OMNI BRAVO?
Over.
SC Roger.
BRAVO.
SC Houston, Apollo 11.
How do you read on BRAVO?
CAPCOM Roger.
Reading you 5 by.
SC Same here.
CAPCOM Apollo 11, Houston.
Looks like we've got a good PTC going.
It's good night from the white team.
Over.
SC Okay.
See you tomorrow.
Thank you for everything.
PAO This is Apollo Control at 60 hours 37
minutes.
We said good bye - goodnight to the crew about
10 minutes ago.
We expect that they will be settling down
their rest period shortly.
And at the present time, Apollo 11 is 184,600
nautical miles from earth.
The spacecraft velocity is presently 3,023
feet per second.
I understand there has been some interest
in a comment made by Nell Armstrong during
the television transmission about the EVA
floodlight.
Armstrong's remark was that the mast which
the light is mounted on, appeared charred.
He reported that the light works but had apparently
the mast that supported it had apparently
been damaged during the launch phase.
This light would be used in the event of a
contingency EVA.
It would have to function in a normal mission
such as we are presently flying.
And in the event that a extravehicular activity
was necessary for transfer of the crew from
the LM into the command service module, the
light would be an aid in providing exterior
lighting of the hand rails, but would- repeat,
that it would have no function in a normal
mission and the charring which Armstrong reported
is not considered significant at this time.
We don't expect to have any further conversation
with the crew.
We will continue to record any remarks that
we get and play those back.
The passive thermal control mode, which was
reestablished, appears to be functioning well
at this time and all spacecraft systems are
functioning normally.
At 100 - rather 60 hours 39 minutes, this
is Apollo Control, Houston.
PAO This is Apollo Control an 60 hours 47
minutes.
We just got a call from the spacecraft requesting
that we give them the position of the S-IVB
in respect to the
spacecraft and we're currently coming up with
that bit of information, so we'll stand by.
SC Houston, Apollo 11.
CAPCOM Go ahead, 11, over.
SC Do you have any idea where the S-IVB is
with respect to us?
CAPCOM Stand by.
CAPCOM Apollo 11, Houston, the S-IVB is about
6000 nautical miles from you now, over.
SC Okay, thank you.
SC Houston, Apollo 11, how is the PTC looking?
CAPCOM Stand by.
CAPCOM 11, Houston.
The PTC looks great to us, over.
SC Hey, do you have any idea what happened
to the previous one?
CAPCOM We have absolutely no idea, over.
SC Okay.
Did it look like it was all right and just
all of a sudden start diverting?
CAPCOM Negative, if you look at the plot which
we'll save for you and let you see it post
flight.
It started off immediately on the first rev
and just spiraled out to about oh, 20 to 20
degrees in pitch, and then it seemed to be
setting up a spiral around an offset pitch
point of about 20 degrees off from 90 degrees,
but we didn't want to take a chance that it
would become stable at that point.
We thought it might diverge so we told you
and started over again, over.
SC Okay, no complaints.
I was just curious as to what had happened.
