Apollo 7

We have been trying - Capsule Communicator Jack Swigert has been trying to reach Apollo 7 remoting through Tananarive without success, we apparently have some problem as yet not resolved through that Tananarive Station and we've had some other communications problems on the the circuit, these are not unusual and we feel very confident in a rev or two we'll figure out the right combinations of antennas and switches and be up to speed in all stations around the Earth. The crew during this period as they move across the Indian Ocean will let us check the Flight Plan here. They're coming in to a sunset - or their in the night - they are in darkness. Donn Eisele is down in the Lower Equipment Bay at his G&N station and they'll be checking electrical voltages very carefully and reporting to them on those checks over Australia and that looks like about the extent of the activity for now. We should hear from them when they come into range of Carnarvon at 4 hours and 5 minutes into the mission. This is Apollo Control, Houston.

This is Apollo Control, Houston; 4 hours, 4 minutes into the flight. We are in touch with Apollo via Carnarvon and Walt Cunningham is going through the circuit breaker check with us to the pyrotechnic lines. We will tune in on the conversation now.

This is Apollo Control at Houston. Apparently not much luck through the ARIA aircraft North of Australia so we will take a line down at this time. The crew we should next hear from the crew when they reach Hawaii at 4 hours and 30 minutes into the flight and at that time they will conduct a bias check on something called the PIPA, the P I P A. PIPA stands for the Pulsed Integrating Pendulous Accelerometer. I hope everybody copied that. It is a part of the guidance system and related to platform kinds of drift in past space flights. At least the check they will perform is that sort of check over Hawaii and on across the States. At 4 hours and 15 minutes into the flight, this is Apollo Control, Houston.

This is Apollo Control, Houston; 5 hours, 6 minutes into the flight. The Flight Director suspects the crew is involved with other matters and has decided we will not attempt to contact them by voice communications which have not been the best through Tananarive today at this point. We are on the fourth revolution around the Earth and all events proceeding very well at this time. This is Apollo Control, Houston.

This is Apollo Control, Houston; 5 hours, 11 minutes into the flight. We have some tape backed up from the last stateside pass beginning out in Hawaii. It was a fairly quiet pass as the crew was eating its first meal in space, but in the course of the pass, Schirra commented that he had - had the - that he had chalked up the - had his first cup of coffee in space. In this particular spacecraft we have water available which is as warm as 150 degrees and Wally insisted on taking some coffee along on the flight, and of course he had to squeeze it into a bag and I am sure it wasn't the easiest thing to drink but he indicated that it was very enjoyable. The crew completed their first meal in the course of the pass and the current orbital numbers read like this: 165 nautical miles by 124 nautical miles. That is as a result of the initial maneuver by the Command Module and the Command Module presently is leading is slightly below the S-IVB. It is about 15 miles separation distance between the two and that is growing - that is growing at a small rate but over a period of perhaps 8 to 10, 12 hours the two will be separated by about 100 miles. Again the orbital numbers are 165 miles by 124. Both nautical readings. Schirra did report that their IVA maneuvers - that is, their moving about the crew movements within the spacecraft changing couches, Donn Eisele moving down to his station in the Lower Equipment Bay did not seem to be generating any change - Delta V kinds of changes within the spacecraft. In other words it wasn't accounting for any great bias or accelerations or deviations from their plotted flight path. As I said, we have got about 10 minutes of tape backed up and we will play it for you now.

This is Apollo Control Houston, 5 hours, 49 minutes into the flight. Spacecraft is nearing the Guam zone of acquisition, the Guam Station to contact Apollo 7 for the first time today. Before we reach Guam let's unload about two to three minutes of tape which we collected during a swing over - a swing which took the spacecraft several hundred miles northwest of Australia. This from Carnarvon.

And now we're talking to Apollo 7 through Guam and here's how that's going.

This is Apollo Control Houston apparently there will be no further comm by Guam so we'll take the circuit down at this time.

This is Apollo Control, Houston, 6 hours, 5 minutes into the flight of Apollo 7. We are talking to Apollo 7 through Hawaii and here is how it's going.

This is Apollo Control, Houston, we're - obviously we and the crew are looking at the O₂ flow. It's in a high mode. And as Walt Cunningham said he can't explain it just yet. We expect to have new contact with the spacecraft via California momentarily. We'll come back to you when we get that. At 6 hours and 13 minutes into the flight this is Apollo Control, Houston.

This is Apollo Control Houston. 6 hours 22 minutes into the flight. We still don't have a good explanation for the fact that we are using oxygen in the high-flow rate position in the cabin. Walt Cunningham - that sort of system falls in purvue of Walt Cunningham over in the right couch. He is working the problem, looking over his checklist and we are working it down here on the ground. There is some belief that it might be a sensor or a faulty sensor and I guess really that is the only possible thing I have heard rumored about. Again, we have no explanation for it at this time. We are watching it. We have some tape from the start of the pass as we move down and across the California - Baja California and down through Mexico. Here is that tape now.

And this is Apollo Control Houston. We are looking at the overall oxygen quantities here naturally, and looking at this oxygen flow, and we show something like 97 percent ... Here is Jack Swigert talking to the crew.

This is Apollo Control, Houston at 6 hours, 27 minutes into the flight. The spacecraft just starting its 5th revolution around the Earth. It is now crossing the 80th [18th] parallel just north of the Panama Isthmus. And in case you missed that last transmission from Swigert, we have considered the oxygen high flow question that has come up since - oh - been looking at it for about the last 10 or 1S minutes since just before the spacecraft was acquired by Hawaii. And we have looked at total usage. We have looked at the cabin pressure and the fact that it is holding at a very steady 5 - 5 pounds to 5.1 pounds per square inch and we are looking at the total quantity and at least at this time we are satisfied that it is simply a sensor error. It is an invalid reading and of course we will continue to look at it, but over that period of time we could see something that would explain a leak or something else. And the data does not show that. The crew, I believe has - we have loss of signal and so that will conclude this message at 6 hours and 29 minutes into the flight.

This is Apollo Control, Houston, 6 hours, 49 minutes into the flight. We had a little, very small audible communication through Ascension a few minutes ago. Here is how that went.

And this is Apollo Control, Houston. At this point Flight Director Glynn Lunney is talking with his various flight directors and asking them to consider very well the performance in their areas of speciality up to this point. Within about 30 minutes when the spacecraft reaches the tracking ship, Mercury, which is parked off the China coast. At that point the Flight Plan calls for Lunney to give the crew a GO for 18 dash 1. And before he does that,in the act of consideration, he wants to carefully weigh all of the up rating situations up to this point which of course have been quite favorable. But at the same time they'll get a very careful screening before that GO is given. The Mercury station should - the Mercury ship is to acquire at 7 hours, 22 minutes into the flight. We are presently 6 hours and 5i minutes. This is Apollo Control, Houston.

And this Apollo control, Houston, 7 hours 03 minutes into the flight. Via Tananerive we've been talking to the crew and here is how that goes.

This is Apollo Control, Houston, 7 hours, 22 minutes into the flight. In a very few seconds the ship, Mercury, parked off the coast of China should acquire the spacecraft now. The acquisition is planned for right now. As a matter of fact, and when it comes we'll cut into it. There will be discussion with the crew over how or what their status is and discussion of the events over the next few hours. Here is that discussion now.

This is Apollo Control in Houston, 7 hours 27 minutes into the flight and to repeat. Flight Director, Glenn Luney has given Apollo 7 a GO for 18-1, a GO for 18-1 and we will go back and try for any additional commentary coming to us by Guam.

[Garbled] 18-1. That was a sign that the crew could proceed to remove their space suits. We have had no positive confirmation that they have started that step yet. But it was - it is an understanding and it is written into their Flight Plan and ours that the suits would start coming off at this point. This is Apollo Control in Houston.

RILEY This is Apollo Control, 7 hours and 39 minutes into the mission. We're just about ready to acquire Apollo 7 at Hawaii Station. We'll stand by for that pass and Seven will go on down through the Huntsville's acquisition area. Here's the call now.

Apollo Control, 7 hours and 45 minutes. We have LOS at Hawaii and we'll continue the monitor through to Huntsville.

This is Apollo Control, Houston; 7 hours, 54 minutes into the flight. Apparently we will have no more comm through Guaymas. The spacecraft will be proceeding down Eastern Pacific, running parallel to the Mexican - Central American area without any further contact. I want to emphasize in that last message the statement that the separation distance between the Command Module and the S-IVB is not running exactly according to the earlier prediction. You recall about an hour, an hour and a half ago, we told you that the two were about 15 miles apart; the Command Module in front and slightly below the S-IVB. And the prediction the Flight Dynamics Officer gave us then was that they would continue to separate at the rate of 4 or 5 miles per hour for a period of 7 or 8 hours, and perhaps reach a maximum separation point of about 100 miles before they would slowly come back together. Now that separation rate is not proceeding according to the reference prediction. We have no new numbers on just how it is proceeding, but they think we can get some together before the news conference which will follow this shift. This is Apollo Control, Houston at 7 hours, 56 minutes into flight.

Apollo Control, Houston; 8 hours, 10 minutes. The second shift of flight controllers is now active in the Mission Control Center, headed by Flight Director Gene Kranz. The CapCom on this shift is astronaut - well, Tom Stafford is still here, but astronaut Ron Evans has just come in too, and will fill out the rest of this shift. We are estimating the new conference now with Flight Director Gene - with Flight Director Glynn Lunney of the first shift for 6:30 pm Central Daylight Time. Apollo Control; 8 hours, 10 minutes.

Apollo Control, Houston; 8 hours, 31 minutes. We're coming up on the Tananarive station now, but we do not intend to initiate any communication with the spacecraft at Tananarive. We will stand by in case the flight crew wants to talk, but the Control Center will initiate communication during the pass. We're over the Pretoria, South African station, but there's no voice capability at Pretoria. If there is any communication at Tananarive we will bring it to you. Apollo Control.

9 hours and 31 minutes into the mission. Apollo 7 is on it's sixth revolution down over the Eastern Pacific. We did have a brief bit of communication earlier in this revolution at Tananarive, and at the tracking ship Mercury Walt Cunningham reported that the Command Module Pilot, Dorm Eisele was settling down for his sleep period. And then over the Hawaii station which we just passed, the Flight Surgeons were successful in passing up some corrective measures for Cunningham to take to fix his EKG instrumentation. We'll bring you the tapes from those passes now.

Apollo Control, Houston; 9 hours, 42 minutes. That's the end of the tape, the CapCom you heard talking to flight crew through Hawaii was Astronaut John Young who's a member of the backup crew who has joined the astronaut Ron Evans at the CapCom console here in the Mission Control Center. Apollo 7's next station contact will be Tananarive at 10 hours, 7 minutes, 30 seconds Elapsed Time. Apollo Control.

This is Apollo Control at 10 hours and 7 minutes Elapsed Time. We coming in to acquisition at Tananarive now. We'll stand by live through this pass.

This is Apollo Control. We have had loss of signal at Tananarive now. As you heard, this is the first change of lythium hydroxide canister. There are two canisters in the system that they are using to remove the carbon dioxide from the recirculated oxygen. One canister is changed every 12 hours. This was the first change right on schedule according to the Flight Plan. The next station to acquire will be the tracking ship MERCURY down off the coast of Japan, down between Japan and the Phillipines. Acquisition time there at 10 hours 30 minutes 40 seconds. This is Apollo Control at 10 hours 16 minutes."

[Riley] This is Apollo Control; 10 hours, 30 minutes into the mission. Apollo 7 is coming up on the tracking ship, Mercury. Should acquire within a few seconds. It is in its seventh revolution. We'll monitor communications through this pass.

This is Mission Control we have had LOS at the Mercury now. You heard Wally Schirra report the partial pressure of oxygen in the cabin as now 190 milimeters of mercury and that is the magic number they have been looking for. That is the sea level equivalent. When they reached that number, they closed the waste management vent valve which is the valve which has been venting the atmosphere introduced to the cabin on the pad; the 60/40 oxygen/nitrogen combination. So that valve is closed now. They are not venting and they do have a sea level in the cabin as far as partial pressure of oxygen. At 10 hours, we'll acquire again in Hawaii in about 8 minutes specifically 10 hours, 48 minutes and this is Mission Control at 10 hours, 39 minutes.

This is Apollo Control; 10 hours, 48 minutes into the mission. Apollo 7 coming up on aquisition of Hawaii tracking station now. We'll stand by through this pass.

This is Mission Control, 10 hours, 56 minutes. We've had LOS since Hawaii. The next station acquires tracking ship Redstone, be a very low elevation pass there. We think we will be able to have voice communications. But the elevation is just slightly over 3 degrees and it'll be a short pass. This operation with the computer during the Hawaii pas was to check the memory after the restart that the computer saw several hours ago. Flight controllers here wanted to double check to make sure that the memory had not been effected, and it appears to be very good at this time. At 10 hours, 57 minutes this is Apollo Control.

This is Apollo Control; 11 hours, 5 minutes. We're coming up on the Redstone now. We'll stand by through that pass.

This is Apollo Control; 11 hours, 10 minutes. We've had LOS with the Redstone. We're along way from the next aquistion we're in the revolutions that go down over the southern hemisphere and the next station to aquire will be the tracking ship Mercury at 12 hours 5 minutes 58 seconds. This is Apollo Control at 11 hours, 11 minutes, 20 seconds.

This is Apollo Control; 11 hours, 43 minutes into the mission. At the last pass of Apollo 7 over a tracking station in this case the Redstone, a tracking ship, Walt Cunningham mentioned a steam pressure anomaly. Flight Director Gene Kranz and some of his flight controllers have been working this problem. They think that we're seeing a freeze up of the water boiler on the primary coolant loop of the spacecraft. The spacecraft is powered down considerably and on the night side of the pass the water boiler does not have to work. But as we come into daylight and heat up, water then does flow to the boilers so that it can get rid of heat by evaporating water, that's what the water boiler does, and then when we go back into the night side in a low power configuration, it's the belief we may be getting a freeze up. There's water still in the boiler and may be freezing up. We're going to get a data dump at the next pass over the Redstone. We have a pass over the Mercury coming up at 12 hours 5 minutes elapsed time, but the Mercury has a problem with their unified S-band antenna which won't allow us to get a data dump there so we'll wait until the Redstone, get a data dump which will give us a better understanding of this problem. At the present time, it appears though to be a freeze up of the water boiler as it goes into the night side. At 11 hours 45 minutes, this is Apollo Control.

This is Apollo Control at 12 hours, 5 minutes into the mission. Apollo 7 is coming up in to range of the tracking ship Mercury on its eighth revolution. We'll monitor communications through this pass.

This is Mission Control; 12 hours, 13 minutes. We've had LOS at the Mercury. A very low elevation pass scheduled at Hawaii this rev nine-tenths of a degree which would give us perhaps 2 minutes acquisition there and we're going to try. Apparently, we'll come back at that time. Acquisition at Hawaii scheduled at 12 hours 25 minutes 12 seconds. This is Apollo Control.

This is Apollo Control, 12 hours 25 minutes into the mission. We'll stand by through this short low elevation pass at Hawaii.

We've had LOS now at Hawaii. The Apollo 7 will be acquired by the Redstone at 12 hours 37 minutes S6 seconds. This is Apollo Mission Control at 12 hours, 28 minutes.

Apollo Control; 12 hours, 37 minutes. Apollo 7 coming up on the Redstone now. We'll monitor this pass.

This is Mission Control. We've had LOS at the Redstone. During the first half of that pass we had very low signal strength, could not raise the spacecraft, finally got word through the network controller that the spacecraft had reported to the ship that they could read us very weak, so CapCom Ron Evans started in the blind with that information but by that time the signal strength came up and we were able to get a little bit of conversation. The Ascension Island tracking station will acquire Apollo 7 at 13 hours, 4 minutes, 41 seconds. At 12 hours, 47 minutes; this is Mission Control.

Apollo Control at 13 hours, 4 minutes into the mission. The Ascension tracking station is about to acquire Apollo 7. We'll stand by through this pass.

This is Mission Control. Ascension has had LOS. We'll be out of touch with Apollo 7 now until it comes within range of the Mercury tracking ship over in the Western Pacific. Over this pass over Ascension, we got a little bit more information for the environmental control officer here towork (garble) the evaporator or the water boiler problem. As you heard Walt Cunningham does not consider it a major problem at this time and the Control Center here concurs with that. They are continuing to work on the problem and are evaluating the telemtry information received in the dump over the Redstone during the last pass. We'll acquire at the Mercury at 13 hours 40 minutes 43 seconds. At 13 hours, 13 minutes; this Mission Control.

Apollo control at 13 hours, 40 minutes, Apollo 7, its ninth revolution coming up on the tracking ship Mercury in the western Pacific. Guam has overlapping coverage with the Mercury on this revolution. We will stand by through both of those passes.

Mission Control at 13 hours 54 minutes Guaymas had LOS. The tracking ship Redstone in the South Pacific will acquire Apollo 7 at 14 hours 12 minutes 38 seconds. We'll be back at that time.

Apollo Control at 14 hours, 12 minutes into the mission. The tracking ship Redstone is about to acquire Apollo 7. We'll stand by through this pass.

This is Mission Control. We have LOS at the Redstone now. During the initial part of this pass, we again had a weak signal strength problem. Didn't get communications with the spacecraft until several minutes into the pass. We passed up the information the crew will need to perform this little extra phasing maneuver that's planned at 15 hours, 52 minutes into the mission. It's required because the drag conditions of the S-IVB, the second stage of the launch vehicle are not as predicted premission and without this burn at the time of the first SPS burn tommorow and that's scheduled for 26 hours and 20 minutes. That's the first burn to in the rendezvous sequence. Without this (Garble) with it's coming up at the time that burn takes place, the S-IVB stage would trail. Correction - the command and Service Module would trail the S-IVB by about 30 miles. When what is needed is for the command and Service Module to be out ahead of the S-IVB. The nominal number is 75 miles and this second phasing maneuver coming up will place the CSM out ahead between 63 and 87 miles of the S-IVB which is still in good position for the MCC-1 or the first SPS burn at 26 hours 20 minutes tommorrow. Apollo 7 will be acquired by the Ascension station at 14 hours, 39 minutes. This is Mission Control at 14 hours, 24 minutes.

This is Mission Control at 14 hours, 26 minutes. This upcoming phasing maneuver will be a burn of 6 and a half feet per second. Propellant cost will be about 27 pounds it is estimated. But even though this is a nonplanned burn and the Flight Plan, there is enough RCS pad in the propellant budget to handle this burn and it will not affect the mission. This is Mission Control.

This is Mission Control at 14 hours, 39 minutes. Ascension has acquired at the Apollo 7 spacecraft. We will stand by.

[Riley] This is Mission Control. We have had LOS at Ascension. Next station to acquire will be the Mercury at 15 hours, 15 minutes. The Apollo 7 at the time of this phasing maneuver at 15 hours 52 minutes will be in contact with the Redstone. At 14 hours, 48 minutes, this is Mission Control.

This Apollo Control at 15 hours and 15 minutes into the mission. Apollo 7 is coming up within range of the Mercury tracking ship now. Guam again has overlapping coverage here so we'll stand by through both of these stations for any communications.

This is Mission Control. Guam as LOS. The tracking ship Redstone in the South Pacific will acquire Apollo 7 at 15 hours 47 minutes 58 seconds. That RCS phasing maneuver is due to take place 15 hours 52 minutes. At 15 hours 30 minutes, this is Mission Control.

This is Mission Control at 15 hours, 47 minutes in the mission. We are coming within range of the Redstone now. We are 4 minutes away from the burn. We will standby through this pass.

This is Mission Control, 15 hours 56 minutes. Redstone has had LOS. The Guidance Officer here in the Control Center affirms that that burn looked good here. And as you heard Wally Schirra and Walt Cunningham are preparing for their sleep period now. We will have a very low elevation pass at the Canary station at 16 hours 21 minutes 39 seconds. This is Mission Control.

This Apollo Control 16 hours 20 minutes into the mission of Apollo 7. We are coming up on acquisition point with Canary Islands in about a minute and a half from now. We will listen in although it is possible that we won't hear anything at that time. The sleep period for the spacecraft commander Schirra and LM pilot Cunningham has begun now. Only about 10 minutes off their schedule. And that was due to the phasing RCS burn of the Service Module. The result of that burn is 83 to 98 nautical miles it will be 83 to 98 miles ahead of the S-IVB at the time of the first SPS burn tomorrow. The next thing to do with the ECS water tank dump schedule is 19 hours into the mission. It will be scheduled for 28 minutes to dump an appropriate amount of water overboard from the spacecraft from the ECS water tank and that can be managed by the one pilot who will be awake at that time. The Command Module pilot, Eisele. We are coming up in acquisition with Canary Islands. We will stand by for whatever may come up from that.

This is Apollo Control 16 hours 23 minutes going on 24 minutes into the mission of Apollo 7. We have passed away from acquistion with Canary Islands. The next contact will be with tile tracking ship Mercury and that will be at 16 hours 51 minutes 49 seconds. This is Apollo Control.

This is Apollo Control. There will be a change of shift press briefing here in Houston at the press center at 10 minutes to the hour. That's approximately 18 or 19 minutes from this time. This is Apollo Control.

This is Apollo Control; 17 hours, 19 minutes into the flight of Apollo 7. We had contact at 16 hours 51 minutes with the Mercury tracking ship and Apollo 7. We will roll that tape now and after that we should have a light pass coming up with Redstone tracking ship.

[JAMES] This is Apollo Control. We are now 17 hours 21 minutes into the Mission. At 17 hours 22 55 we will have contact with the Redstone tracking ship. At that time we will go live and stand by for any communication that we may have.

This is Apollo Control, 17 hours 32 minutes into the mission of Apollo 7. We have the next contact coming up and will be with Canary Islands at 17 hours 55 minutes 11 seconds into the mission. During this pass, we heard passed up the words P00 that the Command Module computer was confirmed to be in an idling mode. From that idling mode, then they passed in a verb and a noun which meant to enter digital entry into the computer to test the pulse integrating pendulous accelerometer to see how it was operating. We also had a report that 75 percent now is the readout on the amount of waste tank water instead of 40 percent. It still stands that at 19 hours the Command Module pilot will dump 28 minutes worth of water from that waste tank. At 17 hours 33 minutes into the mission. This is Apollo Control.

This is Apollo Control 17 hours 52 minutes into the mission. We are coming up on Canary Islands again. We should have acquisition at 17:53:11. And that will last for some 7 1/2 minutes. We will tie into that live. We now have an apogee of 164.4 nautical miles and perigee of 120.1 nautical miles. The spacecraft commander and the Command Module pilot are sleeping and lunar - excuse me - the lunar module pilot is sleeping and the Command Module pilot is awake at this time. There is nothing in the Flight Plan of activity until 19 hours into the mission when he will dump the excess water from the waste tank for 28 minutes. At this time, let's see if we have any contact with Canary Islands.

That is the end of our pass at Canary Islands. At 18 hours into the mission of Apollo 7, this is Apollo Control.

This is Apollo Control; 18 hours, 36 minutes into the mission of Apollo 7. Apollo 7 is coming up on Australia at this time. We will have contact with the spacecraft. However, not necessarily voice contact, but we should be getting it, if any, starting about now. Let's tie into the conversation at that end.

This is Apollo Control 18 hours 44 minutes into the mission of Apollo 7. No contact was made on that pass over Australia. The next possible contact will be with the Redstone tracking ship at 18 hours 57 minutes 30 seconds. At 18:44:52, this is Apollo Control.

This is Apollo Control 18 hours 57 minutes into the mission of Apollo 7. We are coming up now on the Redstone tracking ship. Should have acquisition in a matter of about a minute. We will stand by for any possible conversation.

This is Apollo Control; 19 hours, 7 minutes into the mission of Apollo 7. We had a little bit of difficulty there. Astronaut Pogue was unsuccessful for a minute or so to make contact because the Redstone ship was having some trouble locking up on the voice signal. However, did make contact and the discussion among other things concerned calrification on the biomedical harness where the readouts during the Control Center on high grade, etc. and as of now it is not functioning. Although the medical people say that the power in the equipment is working satisfactorily. So it must be some other problem. Possibly on board. At 19 hours 7 minutes 54 seconds into the mission, this is Apollo Control.

This is Apollo Control; 19 hours, 17 minutes into the mission of Apollo 7. We have just had CapCom contact with Apollo 7. At ANT we will now join the conversation.

This is Apollo Control; 19 hours, 24 minutes into the mission of Apollo 7. We had astronaut Pogue passing up the Flight Plan update which indicates the completion of approximately one day, 23 hours, 53 minutes into the mission. We have the good possibility of live television coming from the spacecraft which will be released that will be roughly about 10 am Central Time tomorrow morning. Correction, this morning would be around the end of the fifteenth revolution. Eisele also reported hearing spurious radio signals. He indicated that it was a radio program and he was getting a hot tip on hospital insurance plans from somebody whereupon astronaut Pogue said maybe they are trying to tell you something and Eisele retorted with maybe they know something I don't. Nineteen hours, 25 minutes into the mission, this is Apollo Control.

This is Apollo Control 20 hours 02 minutes into the mission of Apollo 7. We're coming up very shortly in about a minute and a half in contact with Carnaryon, Australia. At that time we may get some conversation from Cap Com here at MCC and the spacecraft quoting the Flight Plan which is not changed to this time. Shortly after the contact, we are scheduled to have an IMU initial measurement unit realignment using a matrix and it will also at that time they will obtain drift data on the initial gyro and the guidance system. We have several seconds, about 30 seconds to go before initial contact with Carnarvon. At this time we'll switch over and join such conversation as there may be.

This is Apollo Control 20 hours 19 minutes into the mission of Apollo 7. We have just had our pass over Australia. The next contact will be with the Redstone tracking ship at 20 hours 33 minutes 14 seconds into the mission. During our Australian pass, we had some talk about the telescope, referring to the IMU realignment procedures where the telescope and darkness with the sun behind the astronaut and operated satisfactorily and when he moved the optics in the shaft snowy white particles appeared as he said, like a snow storm. At 20 hours 20 minutes into the mission, this is Apollo Control.

This is Apollo Control, 20 hours, 33 minutes into the mission of Apollo 7. We are seconds away from contact through the Redstone tracking ship. We will have contact with the spacecraft at this time. We will be passing up possibly a correction in the Flight Plan which will include a burn of the RCS system to check the Tipa. Here we go. Let's join the conversation.

This is Apollo Control at 20 hours, 39 minutes into the flight of Apollo 7. To clarify what he aid before, it is possible the Flight Director is considering now in view of the fact that the PIPA, which is the pulsed integrating pendulour accelerometers mounted - there are three of them on each of the axis in the initial measuring unit in the Spacecraft and the Y-axis PIPA has been checked over the last many revolutions of the flight and it is possible that in order to check its operation more thoroughly that 1 minute RCS burn would, in an out of plane Y-axis would be utilized and if that were utilized, it would be similar between the 22 and 23 hour of the mission. This was not passed to the crew by Cap Com at this time, it's still under consideration and there's nothing of any alarm, certainly; but we will keep you posted on the progress of that situation. At 20 hours, 41 minutes into the flight of Apollo 7, this is Apollo Control.

This is Apollo Control 20 hours 50 minutes into the mission of Apollo 7. We are coming up on Mila acquisition in Florida and we should have some conversation. That position should be 20:50:19 5 seconds ago. So let's join the conversation.

This is Apollo Control, 21 hours, 11 minutes, 42 seconds into the mission of Apollo 7. As you heard on that communication between Cap Com and Apollo 7, the Flight Director, Jerry Griffin has decided that we need an RCS burn to a minimal burn to check the PIPA or the accelerometer, pulsed integrating pendulous accelerometer counts onboard the Spacecraft. This burn will take place at 22 hours, 23 minutes into the mission. The reason that it is based on telemetery readouts, the PIPA or accelerometer counts may not be getting into the Command Module Computer. Now, this particular Y-axis accelerometer, if you can imagine the Astronauts lying on their couch, the Y-axis would go from hip to hip. So this accelerometer would measure velocity changes and translation along the axis, not around the axis. Therefore, an RCS burn would will take place 22 hours, 23 minutes into the mission and it will be in IMUP, that is the platform, the IMU platform, will be idling, roll 180 degrees, pitch 326 degrees, yaw 0; and they will burn on that Y-axis, along the Y-axis a translation burn for 7 seconds and they will wait for 30 seconds, then they will burn on -Y the other way along the axis for another 7 seconds, and then here in the control center, they will readout whether or not the PIPA counts are getting into the Command Module computer, if it influences the PIPA readouts. At 21 hours, 14 minutes into the mission, this is Apollo Control.

This is Apollo Control 21 hours 37 minutes into the mission of Apollo 7. We are about 10 seconds away from acquisition at Carnarvon, Australia, so lets join what conversation there may be.

This is Apollo Control 21 hours 45 minutes into the mission of Apollo 7. Evidently we'll have no more conversation on our Australian pass. On this revolution, 14th revolution, going - well, correct that, the 15th, the beginning of the 15th revolution we will have the Service Module RCS burn to test the accelerometer and to get a readout hopefully on whether or not the accelerometer counts are getting into the Command Module computer. This is to be done at 22 hours 23 minutes over Texas. At 21 hours 46 minutes, this is Apollo Control.

This is Apollo Control; 21 hours, 54 minutes into the mission of Apollo 7. We had further CapCom communication with the crew of Apollo 7 over Australia and it is taped and I would like to bring it to you now.

This is Apollo Control. That concluded our Australian pass. Our next contact will be on our stateside pass coming over Texas and at 22 hours 23 minutes we will have a burn over Texas of the RCS Service Module engines and that will test the pulse integrating pendulous accelerometer status in the spacecraft. The Flight Director is concerned that possibly this accelerometer, the counts from the accelerometer may not be getting into the Command Module computer. The command pilot and the LM pilot are due to be awakened in a matter of moments on the hour and we should be in contact with Texas and the spacecraft at 22 hours 19 minutes 52 seconds. At 21 hours 57 minutes this is Apollo Control.

This is Apollo Control at 22 hours, 19 minutes into the mission of Apollo 7. At this time, we do not have contact, but we will with the Spacecraft at 22 hours, 1952. The Spacecraft Commander and the LM Pilot should have been awakened on the hour, 19 minutes and 27 seconds ago. There was a lithium hydroxide change scheduled, the second change scheduled in the Flight Plan, which we assumed has taken place. At 22 hours, 23 minutes, we are coming up on the Service Module RCS reaction control system burn to test the accelerometers in the IMU. We now have contact with the Spacecraft. Lets join the conversation.

This is Apollo Control, 22 hours 34 minutes into the mission of Apollo 7. In that pass over the United States, we completed the service propulsion system RCS burn. We gave them an update on the amount of propellant left in the RCS system and we confirmed that the waste water percentage is down to 47.2 percent in quantity, where it had been 85 percent. So the dump was satisfactory and the burn was satisfactory for the PIPA check. To repeat, the purpose of the burn that was not originally scheduled in the Flight Plan was based on the fact that the flight director was concerned because the PIPA which is the pulse integerating pendulous accelerometer in the instrument measuring unit and the guidance and navigation system on the spacecraft. They were concerned that the accelerometer counts may not be getting into the Command Module computer. This is an integral part of the guidance and navigation system. There are three such accelerometers mounted in the instrument measuring unit and they measure along all three axes, X, Y, and Z. This particular accelerometer that was in question was the Y axis accelerometer and that accelerometer has now proven from ground readouts to be operational. The next contact we will have is with Canary Islands, 22 hours 37 minutes into the mission. It is now shortly a little less than one minute from this time so we will switch over for any further communication from the spacecraft.

This is Apollo Control; 22 hours, 45 minutes into the mission of Apollo 7. That concludes our pass. The next contact will be Tananarive; 22 hours, 59 minutes, 39 seconds; some 14 minutes from now. We have a Go for 33 revolutions. Things look good on the spacecraft right now. This is Apollo Control.

This is Apollo Control; 22 hours, 59 minutes in the mission of Apollo 7. At this time I believe we will give a rundown of the activities since roughly 8 hours ago. At 15 hours, 23 minutes; astronaut Schirra requested permission to take one decongestant tablet. He had taken two aspirin earlier. The problem seemed to be that his nose was stopped up and he had gone, as he had said, through several Kleenexes, and at that time he was told to take a decongestant tablet. We then had an unscheduled, up to that - shortly before that time, an RCS Service Module burn. Then the commander and the LM pilot entered a sleep period at 15 hours, 52 minutes into the mission. The reason for the RCS burn was to position the Command and Service Module, some 26 hours into the mission, or 3 hours from now, roughly, well ahead of the S-IVB stage of the booster, which it will rendezvous with at that period in the flight. We will turn out to be, after that burn, 85 to 98 nautical miles ahead of the S-IVB at the time of the first Service Propulsion System burn, so it was a highly successful burn. Then we had a situation where excess water from the Enviromental Control System, primary system waste tank was looked at closely and it turned out that it had to be dumped. Several minutes ago it was accomplished and it went from 85 percent down to some 45 - 47 percent, which is a most acceptable level in the waste tank. We have had some problem with the biomedical harness, which didn't seem to operate and 18 hours, 58 minutes into the mission, it came up and it was indicated by the Command Module Pilot Eisele that he had checked the harness but still on the ground no signal was coming into the Control Center on biomedical readout. So the doctor, Dr. Beers here in the Control Center, indicated that the equipment was working okay and he had to assume that the trouble was somewhere in the spacecraft. At that time, the water tank quantity was building up and had reached 78 percent and it stayed right around that quantity until, as I say, a short while ago it was dumped. It took some 28 minutes to dump it down to around 47 percent. We had Flight Plan update 19 hours, 17 minutes into the mission. We then had it confirmed that the television was scheduled for the Texas pass at some 23 hours, 53 minutes into the mission. At that time, Eisele reported receiving spurious signals. It was a radio program. As he said a hot tip on hospital insurance plans from somebody. Eisele reported 20 hours, 8 minutes into the mission that the telescope when he was in darkness with the Sun behind, he could see the stars fine, but when the object was moved, snowy white particles appeared as he said like a snow storm. He also noticed some Sun shining down the barrel of their telescope at certain times. He did not know the exact position of the Sun when that happened. We're in a situation 20 hours, 29 minutes into flight when the Flight Director Griffin came to the conclusion that the accelerometer in the Inertial Measuring Unit that on the Y-axis possibly was not functioning properly and that the counts possibly were not getting into the Command Module Computer. He then determined that we should have an out-of-plane burn, an RCS - Reaction Control System on the Service Module - burn in the Y-axis that's laterally of - and that the burn would be 7 seconds plus Y and 7 seconds minus Y with a 30 second space in between. Would be a total of about, as it turned out, a 5-foot per second burn. That was passed to the crew and that burn did take place and it did prove that the accelerometer in the inertial measuring unit was not malfunctioning and was checked out here on the ground as working properly. It was then concluded and confirmed that the waste water tank dump was completed, confirmed on the ground - the exact quantity remaining as of now is, or a short while ago, 47.2 percent quantity in the waste water tank in the Environmental Control System. We then got a Go a very short while ago; 22 hours, 30 minutes into the mission; a Go for 33 revolutions. We then had Service Module Reaction Control System readout on quantities. Quad A, we have 86.7 percent left; Quad B, we have 91 percent of the propellant left; Quad C, 85 percent left; and Quad D, 90 percent left. That's the status as of now at 23 hours, 5 minutes into the mission of Apollo 7. This is Apollo Control.

This is Apollo Control Houston 23 hours 33 minutes into the flight of Apollo 7 with the spacecraft just pulling northeast of Australia. During the Australian pass, it was concluded that there would be no television transmission, I repeat no television transmission across the states in the next rev. A number of reasons are cited in the communication from Captain Schirra and here is the tape of the entire Australian pass now.

This is Apollo Control. Again repeat, there will be no television attempt, use of the television equipment made before the rendezvous attempt coming later in the day. And the revolutions are such that we would not then be able to attempt it until at least tomorrow and perhaps the next day. We are undecided right now whether to attempt a television pass tomorrow or not. In the course of the conversation regarding the use of the camera, you heard someone identifying himself as CapCom number 1, come in and PAO take the microphone. That was Donald Slayton. He, on the basis on his discussion with Wally Schirra - here in the Control Center it was concluded that we should not attempt the TV pass today. Prior to that there had been some feeling that we should go ahead and follow the general time line as closely as possible. This is a matter in which the Control Center decided they should accept the crew commanders judgement and that was that it would overload them to attempt before the rendezvous. The principal of additional work, it may sound simple just to turn on the TV camera, but it does mean a good deal of effort in setting light conditions and setting shades, pulling shades on five different windows and controlling the general level. I think that is the biggest order of difficulty. At 23 hours, 42 minutes into the flight; this is Apollo Control, Houston.

This is Apollo Control Houston, 23 hours 51 minutes into the flight. The Guaymas station is due to [garble] we are due to acquire the spacecraft through Guaymas momentarily and this pass will bring the spacecraft across Mexico, across the northern Gulf of Mexico and cut across Florida, should be an active pass [garble] let's listen.
