Apollo 7

[HANEY] This is Apollo Control, Houston; 24 hours, 38 minutes into the flight. We've been in touch with the crew by Tananarive. We are now, and here's how that conversation is going.

This is Apollo Control, Houston; 24 hours, 58 minutes into the flight. We are over Australia and the pass is progressing in this way.

This is Apollo Control, Houston; 25 hours, 2 minutes into the flight. The spacecraft is now proceeding northeast of Australia and we will not expect another contact until perhaps Hawaii, the pass shades in right on the line just below the line of acquisition, looks more like a solid acquisition at the Huntsville. The Huntsville is due to acquire at 19 minutes, 25 hours, 19 minutes into the flight about 16 minutes from now. A word on the visitors in the control center this afternoon, this morning, Mrs. Low Cunningham, the wife of Lunar module pilot Walt Cunningham was here, arrived about 9:50 with their two children, Bryan and Kimberly and they stayed in the control center for about an hour along with a house guest of the Cunninghams, a Mrs. Lynda Johnson. They left here about 10:50. We discussed Schirras admitted cold with Dr. Berry and all hands agree that Wally sounds a little stuffed up, a little husky and you heard him ask for and it was suggested that he take another Actived which is a decongestant tablet. This is the second Actived, he took two aspirin before he went to sleep last night. At 25 hours, 4 minutes into the flight; this is Apollo Control, Houston.

This is Apollo Control Houston, 25 hours, 23 minutes into the flight. We've been in touch with the crew by Hawaii, they're now in the Huntsville, the ship Huntsville zone of acquisition and here is how their conversation is going.

This is Apollo Control, Houston. In this lapse, you will recall in the Morning News Flyer the CapCom references and the message from Vice-President Humphrey. In the full text of that message is as follows: "Hearty congratulations and all good wishes for this historic Apollo 7 mission. The nation is proud." End of statement. Now we will go back to the pass.

Over Ascension the crew simply was advised that we were standing by here. There was no conversation. They are now nearing Tananarive and shortly will be coming up on the first major use - the first use of the SPS, the service propulsion system, to make the first burn setting up their rendezvous. That burn is programed to take place between Tananarive and Carnarvon. I'm sorry it looks like most of it would take place over the Australian in the Carnarvon circle of acquisition. We'll be back with the Tananarive pass. This is Apollo Control Houston.

Apollo Control; 26 hours, 9 minutes. At Tananarive we had this conversation.

This is Apollo Control, Houston. The crew is over Mid-Indian Ocean. They're running through the checklist leading up to the first SPS burn. Presently programed 4 minutes uh 4½ minutes from now. That would make it about 2:25 2:26, 26 hours 25 minutes into the mission. The burn will be, as we said, using the service propulsion system. It will be a 9.6-second burn. Now that might vary ery slightly, but it will be on the order of 9 to 10 seconds. Uh, imparting differential velocity of 207 feet per second. The burn will be done in-plane, in other words, in the direction of flight and the resultant apogee perigee should be 122 by 197 or thereabout. Have the effect of raising the apogee. Our present orbital elements leading up to the burn are a perigee of 120 and apogee of 164. At 26 hours, 21 minutes into the flight; this is Apollo Control, Houston.

This is Apollo Control Houston 26 hours 23 minutes into the flight. We have acquired at Carnarvon and we are standing by. We are about 60 seconds away from the first burn of the service propulsion engine. This burn will be handled by the guidance and navigation system. Standing by for an ullage burn, 15 seconds away from the burn. The countdown from 10, 4, 3, 2, 1 and we are thrusting, the crew reports. Thrust cutoff and it looks like we had about 9 to 10 seconds. Wally Schirra's comment was that was a ride and a half. Walt Cunningham did most of the commentary - most of the advising us to what was going on during that time. So the service propulsion engine, which puts out something like 21,000 pounds of thrust, has passed its first major test in space. And now we have compared the data here, and it was a 10 second burn. It's been quiet from the spacecraft since the burn. We are looking at the data here, we got it by the Carnarvon station. The spacecraft, at the start of the burn, was about 300 miles due west of the Australian continent, about due west Perth. Donn Eisele has just checked in, he is happy with the burn in all respects. Here is the tape of the entire sequence as it occurred. [Pause]

This is Apollo Control Houston 26 hours 34 minutes into the flight. We may have some additional comm through an ARIA aircraft off the north coast of Australia, but it is really rather doubtful. The burn was completed, the burn at 26 hours 25 minutes into the flight. It was 10 seconds duration. It was the first burn of the service propulsion engine imparting a differential velocity of 207 feet per second. Our resultant apogee and perigee are 125.3 nautical miles, 125.3 nautical miles perigee, 196.1 nautical miles, 196.1 nautical miles apogee. Those are the new elements of the flight, and the burn was normal in all respects. This is Apollo Control Houston.

This is Apollo Control Houston, 26 hours, 49 minutes into the flight. We have just acquired by the Hawaii station. We should have a good long pass here. We're on the 17 rev, it should carry us all the way over the Antigua station and will pick up again quickly at Ascension. The - I'm sure the most recent burn will be discussed, as we move across the States and let's find out what else. There is no conversation on the loop right now and - but we do have this opening conversation a few seconds ago as we moved in to Hawaii. Let's listen to it now.

That was Dorm Eisele you heard saying that he thinks he saw the booster, which would be about 100 miles away according to our last check. Possible, I think certainly possible. We will leave the line open and continue the moderator.

This is Apollo Control, Houston, 27 hours 16 minutes into the flight. We still have a little ways to go in the Antigua circle, but it's questionable whether we will have any more COMM with the crew unless perhaps we pick them up again in Ascension. We've been looking here at the consumable chart on weights up to date, and actually these numbers are coming to us from Antigua. They read like this: the Command Module dry weight - that is if there were no other weights aboard: The present dry weight reading of it is 12 205 pounds; Service Module dry weight, 8630 pounds. We have some additional readings here on the various - uh the four quads. RCS quads, the reaction control system quads on the Service Module. They go like this: quad A, propellant weight - total propellant weight in pounds, 281; Quad b, 289 pounds; Quad C, 276 pounds; Quad D, 288 pounds. The SPS fuel propellant weight in the Service Module 3374 pounds and we just lost the chart. Stand by one until we find which channel it was switched to. I'm sorry, we've lost the chart. It's - we will locate it and come back to you and -. The crew has just been given a 60 seconds to LOS and in which they Rogered. This is Apollo - This is Apollo Control Houston.

This is Apollo Control, Houston; 27 hours, 27 minutes into the flight. Via Ascension we have had this conversation.

This is Apollo Control Houston 27 hours 51 minutes into the flight. We've got some conversation through Canary. We will play that for you in just a moment. Before we get to that, one or two other things. We've got some data here taken on the last pass over Ascension where we looked at the heart rate, some of the physical parameters on board the spacecraft and some of the specific physical parameters on the lunar module pilot, Walter Cunningham. They look like this. His mean heart rate was 66, his respirations were 21 per minute, and then as to the cabin, the cabin pressure at Ascension was 5.1 and very steady, cabin temperature 69 degrees Farenheit. I guess those are the pertinent readings on that chart. The S-IVB, the second stage coming on this second burn, which will be performed about 8 minutes from now over Carnarvon, second in a series of burns to bring off the rendezvous with the S-IVB. The present position on that S-IVB is about 80 miles trailing the Command Module, about 80 miles trailing it. It will reach a maximum separation according to our plots, of about 87 miles, just a minute or two before the burn. We have now the Tananarive conversation, let's play it.

This is Apollo Control Houston, 27 hours, 57 minutes into the flight. We have established contact by Carnarvon and we're about 2 minutes away from our second SPS burn today. Burn program for about 8 seconds, a differential velocity of 175 feet per second. We'll you in on the conversation, Jack Swigert is going to give the crew a mark of 2 minutes.

We've just given a mark of T-2 minutes. Cunningham advises he's standing by for a 30-second mark. This burn is programed to have the effect on the orbit resulting, should be 114 by 154 nautical miles. We're 1 minute away from the burn. 8, 7, 6, 5, 4, 3, 2, 1 and we are thrusting, Schirra says. Pressures in the service propulsion engine are quite good and I think we heard thrust off. And as the pitch and yaw thrusters are shutdown, they are reported by the crew. SPS burn, according to the chart here began at 28 hours, 1 minute, 6 seconds into the flight. It ended at 28 hours, 1 minute, 14 seconds, an 8 second burn. The other burn set us up on a circular plane which has carried us around to a point where we are now firing the booster about 85 miles. Now we will begin closing and at about 1 hour, 25 minutes from now, at 29 hours, 23 minutes we should begin the terminal phase of initiation burn, which will be the final burn on bringing us from a point we're on a plane now running about 8 miles under the line on the line of flight of the booster and this will swing us up to hopefully the rendezvous with the booster, coming up just slightly in front of it, we estimate and about 30 hours into the flight. Here is the entire tape through the second burn sequence. We'll play it for you now.

This is Apollo Control, Houston, 28 hours 25 minutes into the flight. Hawaii should acquire momentarily and we will be listening for that pass which will take us across the states. Early today we were talking about a chart which got unlatched in the middle of our transmission as we are discussing onboard weights, we've since run that chart down and of interest to us on it and I hope to you will be one way the current total Command Service Module weight, which is - carried at 30,980 pounds. Now we have contact with the crew, now let's find out what's going there.

This is Apollo Control, Houston; 28 hours, 47 minutes into the flight and we are about half way through perhaps the longest and quietest state-side pass in our memory. The crew is working on the rendezvous, they are rapidly approaching the terminal phase of it and we can only assume that accounts for the quiet. We have the line open and we'll just leave it open and continue to monitor the situation whatever might develop.

This is Apollo Control, Houston. We are out of range of the spacecraft and at 28 hours, 56 minutes into the flight that's our situation.

This is Apollo Control, Houston 29 hours 17 minutes into the flight. The Spacecraft is over the southern tip of Africa and we are about to acquire via Tananarive whether there will be any conversation, we don't know. We have gotten some numbers on the first two burns using the service propulsion system - the big engine and they go as follows: the first burn performed earlier in the day used 674 pounds of propellant. That's a combination of fuel and oxidizer. Again, 674 pounds in the first burn. In the second burn, 565 pounds of propellant used and the combination leaves in, in a, leaves in the service propulsion system propellant tanks 8255 pounds remaining. Now additional burns have been done throughout the night and throughout the day with the Service Module reaction control system thrusters and up until this point we have logged the total usage of 262 pounds, 262 pounds of propellant in the RCS and that leaves a remainder of 1045 pounds. Tananarive should acquire momentarily and when it does we will come into that conversation. In about 5 minutes - or more precisely at 29 hours 23 minutes into the mission, 4 minutes from now, the spacecraft should be trailing the S-IVB by about 12 miles and it should be running about 8 miles below the S-IVB and at that point, approximately 29 hours 23 minutes they will begin terminal phase initiation. There's the first call going out to 7 via Tananarive.

This is Apollo Control. I don't see any point in deafening everybody in the news center. We will come back as soon as we get a cleaner signal. Out at 29 hours, 20 minutes.

This is Apollo Control Houston, 29 hours, 22 minutes into the flight. We have a little tape by Tananarive; it is unreadable but we'll let you hear it anyway, and if you can understand what they're saying, you're better than a lot of people that tried to hear it. We did pick out one or two words on it that the crew had gone ahead with the TPI, the Terminal Phase Iniation, of the rendezvous situation and they are using a program which called 4 TPI at 29 hours, 17 minutes; earlier I gave you 29 hours and 23 minutes; I want to correct that. They did begin the TPI burn at 29 hours, 17 minutes. We'll all know when they get to Carnarvon how everything came out. Here's that Tananarive tape.

This is Apollo Control Houston, 29 hours 52 minutes into the flight. In one small historical note perhaps worth mentioning, it was nearly 3 years ago, lacking 3 years by 2 months, that the same spacecraft commander Wally Schirra, then in command of Gemini 6, carried out the world's first rendezvous over perhaps very nearly the exact same piece of real estate when Gemini 6 pulled up in front of Gemini 7. That rendezvous took place over the Islands just north to northwest of Australia, and apparently if everything continues to go as well as it has in this maneuver, Apollo 7 will pull up in front of the S4B in almost precisely the same location. It will be another 11 minutes before we get any definitive information probably on just how the maneuvers go and that information should come to us through Guam. This is Apollo Control, Houston.

Apollo Control, Houston here, 29 hours 45 minutes into the flight, and we've been having some power difficulties in building 1 today as opposed to building 30 yesterday. Everything back - is up now and operating again. I understand even the phones are working. They were out for about 5 minutes. We've got a little tape from Canarvon then we'll patch right into the Guam area which is about to acquire. Here's the tape and then we'll go into a live pass across Guam.

Apollo Control here. The program shows that they should be in their breaking mode about 1 mile out at this point. We have not heard from them, We do have some data coming in from Guam that shows them approximately 1 mile from target. We just heard Gene Cernan comment. He's been plotting in here that, uh - his statement was "they're right on the pike." We'll monitor the open line.

I understand they're inside of a mile and braking. Braking like hell as one flight controller just put it.

A lot of thruster activity showing up on our charts here. As we look at the RCS quads using all four of them here now again. We're getting some educated guesses that they ought to be on the order of a half mile from the S-IVB. They have not said anything as we move through the Guam area. Still got about half of it to go. Another 2 or 3 minutes. Earlier, we gave you a prior to this vital maneuver, we showed 1045 pounds of propellant remaining in the RCS quads. All four quads now are down the range of about 180 to 190. All of them with the exception of one, under 200 pounds, and all four quads very active. So, we've got something - we've used about 250 pounds of RCS fuel, it would appear, on this maneuver to date, which is pretty conservative usage.

This is Houston, uh, you heard Schirra say he was about 400 feet away from the target, braking at 50 to 60 feet per second, and it seemed to be going very nicely. The time of that last transmission of the spacecraft was at a latitude of 20 degrees North, a longitude of a 100 and about 150 degrees East, 150 East, 20 North. Let's make that 155 East and 20 North. 155 East, 20 North. We have lost signal now by Guam. We don't know what the situation was with the S-IVB, what it's attitude was. We'll know more in about 8 minutes when we get to Hawaii. At 29 hours 53 minutes into the flight, this Apollo Control, Houston.

This is Apollo Control ttouston, 30 hours, 20 minutes into the flight. And only a few minutes ago, we were within contact by the Texas station with Apollo 7 flight Crew Operations Director Deke Slayton. He had a conversation with the crew regarding - he congratulated them on the performance of the rendezvous today and he also discussed the future use of the television camera. Here is the recording of that conversation.

This is Apollo 7, Houston; 30 hours, 22 minutes into the flight; that last conversation primarily between Don Slayton and Wally Schirra. In the course of it, if you followed it, the Apollo 7 crew commander agreed and committed to the use of the television camera from Rev 45 on as per Flight Plan. Earlier in the day there had been some discussion it was scrubbed as an event leading up to the rendezvous which was carried out most successfully in the last few Revs and we will not attempt any television tomorrow because of the sleep cycle. We are next scheduled for that experiment on Rev 45 which will be Monday morning. At 30 hours and 23 minutes into the flight, this is Apollo Control Houston.

This is Apollo Control 30 hours 52 minutes. Apollo 7 is nearing acquisition at Tananarive. We will monitor through that pass.

We have LOS at Tananarive. This is Apollo Control 31 hours 1 minute.

This is Apollo Control; 31 hours, 41 minutes into the mission. Apollo 7 is within range of the tracking ship Huntsville now. We have tape of the passes at the Mercury and the Hawaii station prior to this. We'll start with the tape at Mercury and play catchup.

Apollo Control, 31 hours 50 minutes. The next station to acquire the spacecraft will be Tananarive at 32 hours 27 minutes.

This is Apollo Control at 32 hours, 27 minutes. Apollo 7 is in it's 21st revolution coming up now on the Tananarive Tracking Station. We'll listen in through this pass.

LOS at Tananarive now. The Tracking Ship Mercury will acquire at 32 hours, SO minutes. This is Apollo Control at 32 hours, 36 minutes.

This is Apollo Control; 32 hours, 50 minutes into the mission. Apollo 7 is about to acquire at the Mercury Tracking Ship.

This is Apollo Control. Mercury has LOS now. Hawaii will acquire at 33 - 8. We're attempting to get the heart rates on Wally Schirra during that exercise. If you will stand by, we'll come up with those in just a minute.

This is Apollo Control 33 hours 4 minutes into the mission. Flight Surgeon John Zeiglschmid reports that Wally Schirra was already exercising as they came into the pass and he started monitoring with rates of 88 and those rates climbed right up to 96 as he continued to use the inflight exerciser. He reports Captain Schirra's normal base heart rates at 65 to 75. At 33 hours 5 minutes this is Mission Control.

This is Apollo Control 33 hours 8 mintes and the Hawaii station is about to acquire Apollo 7. Tracking ship Huntsville has a slight bit of overlapping coverage on this pass. We will stand by now.

The Huntsville has LOS now. This twenty first revolution is too far east for the Redstone to acquire Apollo 7. So we will be out of range of any tracking stations - that is Apollo 7 comes down across the South Pacific, South America, and the South Atlantic Ocean. And the next station to acquire will be Tananarive at 34.hours, 3 minutes. At 33 hours, 21 minutes, this is Apollo Control.

This is Apollo Control 34 hours 3 minutes and Apollo 7 coming up on Tananarive station. Capcom Ron Evans plans to just put in a call and telling them we will standby through the pass. We don't intend to initiate any communication here, but we will stand by to monitor anything the flightcrew might care to communicate to us.

We are getting so much crosstalk and noise here that will punch off and come back up if there is any communication on this pass.

This is Apollo Control, 34 hours 8 minutes. There will be no more communication at Tananarive. We'll pick up the Mercury at 34 hours 25 minutes. At this time we are planning a change of shifts in the Control Center between 23:00 and 23:30 p.m. Central Daylight Time which would place the News Conference with Flight Director Gene Kranz between 23:00 and 24:00 Central Daylight Time. Apollo Control.

This is Apollo Control 34 hours 25 minutes into the flight. Apollo 7 has just been acquired at the Mercury tracking ship. There is a call now.

This is Apollo Control, We have LOS at the Mercury now. Hawaii will acquire 34 hours 43 minutes. At 34 hours 33 minuts this is Mission Control Houston.

This is Apollo Control at 34 hours 43 minutes. Apollo 7 coming up on Hawaii now on it's 22nd revolution. The Hawaii station has just acquired. We'll stand by and wait for a call.

This is Apollo Control. We've got about a minute to LOS. It seems doubtful we'll have anymore transmissions on this pass. We'll come back up if we do.

LOS at Hawaii now. The tracking ship Redstone in the South Pacific will pick up the spacecraft at 34 hours 59 minutes. This is Mission Control Houston at 34 hours 51 minutes.

This is Apollo Control, 34 hours, 59 minutes, Apollo 7 coming within range of Redstone now.

This is Apollo Control, Redstone has loss of signal now. Water chlorination is the only task spelled out in the flight plan for the next hour; since we didn't get an answer back up to them, I suspect that they wont do anything about it till we get to Ascension. We estimate, acquisition at Ascension at 35 hours, 26 minutes, at 35 hours, 6 minutes. This is Mission Control Houston.

This is Apollo Control 35 hours 26 minutes into the mission. Apollo 7 coming up Ascension now in a low elevation pass but we may be able to get two to three minutes of acquisition here we'll stand by.

This is Apollo Control at 35 hours 29 minutes. We went by Ascension without attempting to communicate with the spacecraft on this low elevation pass. Next station to acquire will be the tracking skip Mercury. Acquisition there at 36 hours.

This is Apollo Control at 36 hours into the mission. Apollo 7 coming up on the tracking ship Mercury now. The station at Guam has overlapping coverage so we'll have a fairly long pass here. We have acquisition at the Mercury and we'll stand by for some communication.

This is Apollo Control. Guam has LOS now. Very - bad communication through those passes. Redstone will acquire at 36 hours, 32 minutes. We will not pick up the HAW station on this pass. We are still estimating a ship change here in the control center at approximately 11 to 11:30 central daylight time which would put the news conference from starting between 11:30 and midnight. At 36 hours, 12 minutes, this is Mission Control, Houston.

This is Apollo Control 36 hours 32 minutes into the mission. We are about to acquire at the Redstone. The sextant calibration test that was scheduled for this time and that Wally Schirra asked to be postponed until the Command Module pilot, Donn Eisele is awake, will be postponed looking now at about 42 hours and a half into the mission. Estimated time when the sextant calibration test will probably be performed. Redstone has acquired. There hasn't been a call up to the spacecraft yet, but we will stand by for that.

This is Apollo Control; 36 hours, 41 minutes. Redstone has LOS now. As you heard, they passed up the bad news on the football game to Naval acadamy graduates, WalIy Schirra and Dorm Eisele. Air Force 26, Navy 20. This is mission Control 36 hours 41 minutes.

This is Apollo Control, 36 hours 59 minutes into the mission. Ascension has just acquired Apollo 7.

This is Apollo Control, 37 hours 3 minutes. This water correlation [chlorination] was accomplished by injecting an ampule of chlorine into the water tank with a syringelike device. It's about an ounce of chlorine. We're in a process of changing over the shift now and the shift headed by Jerry Griffin will be up very shortly.

This is Apollo Control 37 hours 33 minutes into the mission. We are coming up now with a pass in the Mercury tracking ship. We did have some further communication after the change of shift here on the Ascension pass between MCC and Apollo 7. We will play and then go live into the possible communications between Mercury tracking ship and the spacecraft.

This is Apollo Control 37 hours 49 minutes into the mission of Apollo 7. During this last pass which was rather a long pass including the Mercury tracking ship and Guam. We heard the crew complimented for a good rendezvous today. Spacecraft Commander Shirra is reluctant to change the sleep cycle, that is for all three to sleep at the same time. They indicated that the sleeping bags were not working out too well and that the seat belt in the seat works better than the sleeping mode or rather in the couches than the sleeping bags. The lightweight head are better than the com carrier because the cable jerks their heads around. They indicated a possible problem with the Hasselblad camera and just indicated before LOS that they have finished chlorinating the water onboard. The next contact will be with Redstone tracking ship. That will come at about 38 hours 47 minutes into the mission. At 37:51, this is Apollo Control.

This is Apollo Control 38 hours 7 minutes into the mission. The spacecraft commander and the LM pilot are now in an eating period. The Command Module pilot is in a sleep period. We should have contact with the Redstone tracking ship very shortly now - in 1 or 2 seconds. There's nothing scheduled in the flight plan for contact but let's stand by.

This is Apollo Control, 38 hours 16 minutes into the mission of Apollo 7. We have loss of signal at Redstone tracking ship. The next contact will be at Ascension Island 38 hours 33 minutes into the mission. This is Apollo Control.

This is Apollo Control 39 hours 7 minutes into the mission of Apollo 7. We are in the 25th revolution coming up on acquisition with Mercury tracking ship. 39 hours 10 minutes. We have a tape of the last pass over Ascension which we will play first and then we will go right into the live standby on the Mercury tracking ship. So we will now play the tape of the Ascension pass.

This is Apollo Control 39 hours 23 minutes into the mission of the Apollo 7. We have just had quite a long pass through the Mercury tracking ship and Guam. The next contact with the Redstone tracking ship at 39 hours 42 minutes 34 seconds. At 39 23 this is Apollo Control.

This is Apollo Control 39 hours 42 minutes into the mission of Apollo 7. We are coming up on the Redstone tracking ship and a very few seconds we will stand by for whatever may transpire there.

This is Apollo Control; 39 hours, 51 minutes into the mission of Apollo 7. We have just completed our pass with the Redstone tracking ship. Next contact will be Canary Islands, which should come about 40 hours, 14 minutes, 17 seconds. During this last pass, we went through an inertial measuring unit realignment. The inertial measuring unit of course provides basic reference against which you can measure spacecraft movement and it has to be realigned periodically. We were informed that Astronaut Schirra took one Actifed and two asprins and Astronaut Cunningham one Actifed and Astronaut Eisele some nose cream was applied to his nose. We have had no biomedical readouts during this last pass and the medical people and the Flight Director now conferring in tracking down the situation to see if we can tune that up and get some biomed readouts in the next passes. At 39 hours 52 minutes, this is Apollo Control.

This is Apollo Control; 40 hours, 14 minutes into the flight of Apollo 7. We are in the twenty sixth revolution coming upon Canary Islands in a few seconds. We will join such conversation as we have at the Canary point now.

This is Apollo Control. We have had lost of signal, Canary Islands. Apollo 7 will now go for about an hour before we have contact at the Redstone - Redstone tracking ship. That will be - 41 hours, 17 minutes, 24 seconds into the mission. The program 52, inertial measurement, measuring unit realinement was confirmed to have been completed. The only thing that should take place between now and the next station contact will be the water waste tank dump and the environmental control system which will take place at 41 hours into the mission. At that point also, the spacecraft commander and the lunar module pilot will enter their sleep period. And Don Eisele, the Command Module pilot will be awake and on duty. So we have a long dry spell for 1 hour before the next station contact. At 40 hours, 20 minutes into the mission, this is Apollo Control.

This Apollo Control 41 hours 17 minutes into the mission of Apollo 7. We're approaching the Red Stone tracking ship and astronaut Stafford is endeavoring to make contact with the spacecraft. Let's join them now.

This is Apollo Control 41 hours 26 minutes into the mission. We've finished our Redstone tracking ship pass. The next point will be Antigua at 41 38. They spoke about when to dump waste water. The crew desires to dump it when 90 percent quantity is reached, however they're talking about it now. It's possible that that would be reached right in the middle of the spacecraft commander and LM pilot sleep period; in which case astronaut Schirra would have to be disturbed so they could get the equipment out to dump the excess water. That will probably be resolved by the time we have contact at Antigua. We're still getting no bio-medical data readouts and they can only assume that there's some mechanical difficulty with some of the equipment. At 41 hours, 27 minutes into the mission into the mission this is Apollo Control.

This is Apollo Control; 41 hours, 38 minutes into the mission of Apollo 7. We're coming up and should have access with Antigua just about now. Let's join the conversation and see what goes on.

This is Apollo Control. Our next contact will be Canary Islands at 41 hours 47 minutes, about 5 minutes from this time. The most significant thing in the last two contacts, of course, has been in the flight plan we have changed the S-IVB tracking time from 46 hours and 15 minutes into the mission back to 44 hours and 36 minutes into the mission. The reason being that the S-IVB will be at 169 nautical miles from the spacecraft at 44:36 where if they waited another revolution, it would be farther away from the spacecraft. They desire to track it at roughly that 170 nautical mile distance. We'll come up again when we have contact with the Canary Islands in some four minutes or so from now. At 41 hours 43 minutes, this is Apollo Control.

This is Apollo Control 41 hours 47 minutes into the mission of Apollo 7. We're coming up in a few seconds with acquisition with the Canary Islands tracking station. We'll join them now.

This is Apollo Control, 41 hours 57 minutes into the mission. We are out of range now with Canary Islands. At 42 hours 32 minutes, they will be in range of Honeysuckle in Australia. They have checked the O₂ flow high rate as the readout was before, the check waste vents were closed and when that happened, the O₂ rate came down from 94 and it came down to 70.7 ah .94 to .72 pounds per hour which is quite acceptable. So, with everything looking good at 41 hours 58 minutes into the mission, this is Apollo Control.

This is Apollo Control, 42 hours 32 minutes into the mission. We are coming up on our pass over Honeysuckle Creek. We're halfway through Australia now and we should have contact with the spacecraft in a very few seconds. We'll stand by for such contact.

This is Apollo Control; 42 hours, 39 minutes into Apollo 7. We had no response from the spacecraft during this pass at Honeysuckle Creek in Australia. We should have some contact at the Redstone tracking ship which will have acquisition at 42 hours, 52 minutes into the mission. At 42:39, this is Apollo Control.

This is Apollo Control; 42 hours, 52 minutes into the mission. We are coming up on the Redstone tracking ship acqusition period now. Let's listen in.

This is Apollo Control; 43 hours, 1 minute into the mission. We will have the next station contact at Antigua; 43 hours, 10 minutes; 9 minutes, 8 from now. At 43:02, this is Apollo Control.

This is Apollo Control; 43 hours, 10 minutes into the mission of Apollo 7. We're now coming into Antigua. We should have contact any second with Antigua. Let's join the conversation.

This is Apollo Control 43 hours 19 minutes into the mission of Apollo 7. We'll have acquisition by Canary Islands at 43:21:59, that's only two or three minutes from now. We heard from Mr. Eisete that the VHF high pitch interference noise was coming in as they were passing Antigua and astronaut Pogue indicated that that was the same place where the spacecraft had picked up the spurious noise of last night. They are now looking into this to see if we can track it down. At 43 hours 20 minutes into the mission, this is Apollo Control.

Minutes into the mission. We're coming up on Canary Islands now, 43:21:59 about 30 seconds from now. We'll see if we get any resolve on what the VHF interference was. Let's listen in.

This is Apollo Control; 45 hours, 31 minutes into the mission. We have our next station contact coming up which will be Carnarvon, Australia and that will be coming up 43 hours, 57 minutes, some 27 or 28 minutes from now. At 43 hours 31 minutes into the mission, this is Apollo Control.

This is Apollo Control 45 hours 57 minutes into the mission of Apollo 7. We are approaching Australia now and we will be in contact very shortly with Carnarvon. At this pass there will be an MCC update in preparation of the S-IVB tracking which will take place at 44 hours 36 minutes into the mission, so let's monitor this conversation.

This is Apollo Control. We still have one more minute of acquisition at Honeysuckle Creek but it doesn't appear that any more transmission will take place. The CapCom Pogue here in the Control Center indicated and then we sent up an update front the Control Center for the purpose of preparing the spacecraft for the S-IVB tracking which will take place 44 hours 30 minutes into the mission. That will be in the 28th revolution, it will be coming out of the night side pass, going into the daytime. They will track the S-IVB which will be about 169 nautical miles away and he will track between the Redstone tracking ship and Central American coast. The next point we will have contact with the spacecraft will be the Redstone tracking ship, that will take place at 44 hours 28 minutes into the mission. At 44 14, this is Apollo Control.

This is Apollo Control, 44 hours, 28 minutes into the mission of Apollo 7. We're coming up on acquisition with the Redstone tracking ship in a few seconds. We'll monitor that conversation now.

This is Apollo Control, 44 hours, 32 minutes into the mission. We have just lost contact with the Redstone tracking ship. The next contact will be Grand Bahamas Islands, 44 hours, 43 minutes into the mission, some 8½ - 9 minutes from now. At 44 hours, 36 minutes we will begin the S-IVB stage tracking at 169 nautical miles distance from the Spacecraft. Now we will go back and have in this period of time - we have here a couple minutes of update of what went on in the last 7½ to 8 hours of the mission. At 37 hours, 2 minutes we had a flight plan update. We also found that everybody has evidence of Astronaut Stafford telling the crew that it was a very good rendezvous that day - yesterday. Astronaut Schirra was reluctant to change his sleep cycle as inquired into from the Control Center by Deke Slayton. He indicated the sleeping bags were not working out too well, that the astronauts being in their couches with the seat belt buckled were much more comfortable and it worked much better than when they used the sleeping bags. The light weight head-sets, he said, were better than the com carrier. Because with the com carrier, the cable jerks the head around when they move around tile cockpit. He indicated they had a problem with the Hasselblad camera, what that problem was - what extend it was I do not know. They finished chlorinating the water again and also astronaut Schirra indicated that the Exergenie, the exercise device onboard the spacecraft was "the best one of the best spacie things we've had in years". He also indicated they were getting around in the spacecraft very well and they were becoming gymnasts. We had normal inertial measurement unit realignments, we had an indication that astronaut Schirra took a decongestion tablet, an Actifed tablet plus 2 aspirin, and that astronaut Cunningham had taken one Actifed tablet, and Astronaut Eisele had used some nose cream for his nose. This was at 39 hours, 43 minutes into the mission. There was no particular physical problem indicated beyond the indication that they had taken that medication. At that time we had no biomedical readouts. Later on in the mission at 41 hours, 47 minutes, the biomedical readouts begin coming in to the MCC, satisfactorily. They performed a waste water dump, as they had the day before and there is no problen in the ECS system in dumping the water and having the ECS operate properly. They completed a sextant check well into the tour at 41 hours, 17 minutes and had a flight plan update on the S-IVB tracking time. That was when we changed the tracking time to 44 hours, 36 minutes into the mission instead of 46½ hours. Due to the fact that the S-IVB would be in the 169 nautical mile proximity at 44 hours, 36 minutes and it would be too far away a revolution later. This tracking procedure with the S-IVB will begin very shortly, in fact, it has begun over 1 minute ago. It was indicated at 41 hours, 47 minutes that the O₂, the oxygen flow rate as monitored at MCC in Houston, was indicating a high flow rate. It was also indicated to the crew at that time, that they should check the waste vent and close it if it were open, which it was. After that was accomplished, the O₂ rate came down satisfactorily and is now riding around 0.35 lbs per hour - 0.35 pounds per hour. Waste vent was turned off, still had onboard that was high at that time, but it did come down to that 0.35 pounds per hour. The last - one of the last contacts that was indicated by astronaut Eisele that the VHF high pitch interference noise was coming in. That was indicated to him through - around the Antigua area by Astronaut Pogue that last night the same type of interference came in when he picked up music and voice conversation in that particular area. The crew appears to be in good condition. The spacecraft commander and the LM pilot are in their sleep period and Command Module Eisele is now should be in tile process of tracking the S-IVB. At 44 hours, 39 minutes into the mission, this is Apollo Control.

This is Apollo Control, 44 hours, 43 minutes into the mission of Apollo 7. We are now coming up to the acquisition point at Grand Bahama Islands. We'll stand by for any possible conversation.

This is Apollo Control; 44 hours, 54 minutes into the mission. We won't have acquisition at Canary Islands for another 2 minutes and 20 seconds or so. Astronaut Eisele indicated to the MCC that the tracking with the sextant, the visual tracking of the S-IVB was going along. He said it was not as good as it could be due to bright Earthshine. However, it was still there and you could still track it with the sextant. We'll be coming up at Canary Island pass in just a couple of minutes now. At 44 hours, 54 minutes; this is Apollo Control.

This is Apollo Control; 44 hours, 56 minutes, 35 seconds into the mission of Apollo 7. Canary Islands will acquire in about 10 seconds from this time. We will monitor that pass.

This is Apollo Control Houston 45 hours 32 minutes into the flight. Donn Eisele just put in a call to us via Carnarvon. He said he could still observe the flashing lights on the S-IVB. Here is a rundown on the weather today around the world, some of which the crew may be able to observe on this upcoming rev as they go through the Windward Islands area. Taking it from the top: in the west Atlantic recovery area the weather will be partly cloudy to mostly cloudy with a few showers, winds will be mostly easterly, ranging from 10 to 18 knots, sea is 5 feet and the temperature is in the upper 70's. In the eastern Atlantic, weather will be mostly fair, with northeasterly winds of 15 knots, sea is about 3 feet, temperature in the 70's. In the west Pacific landing area, weather will be fair to partly cloudy with a few showers, winds will be mainly northerly 15 knots, seas 5 feet and temperatures in the 60's. In the mid-Pacific, weather will be cloudy with showers, strong easterly winds and moderately rough seas in the more northern landing areas. In the southern part of the zone, weather will be partly cloudy, winds southerly 12 knots, seas 4 feet and temperature in the 70's. An interesting weather feature that the crew may be able to observe today will be a disturbance in its formative stage in an area a few hundred miles east of the Windward Islands in the Atlantic Ocean. The command pilot and the lunar module pilot remain asleep, and the sleep period is programed to last several more hours. As a matter of fact, it is programed to last 5 more hours, so it looks like a nice quiet morning ahead of us. At 45 minutes hours and - we do have some tape from Carnarvon and we will play it for you now.

Apollo Control Houston, you're 46 hours, 13 minutes into the flight. Jack Swigert just put in a call to Apollo 7 and gave them a standing by message. We'll monitor and see if any conversation developed.

This is Apollo Control 46 hours, 42 minutes into the flight. The crew was advised during a recent pass through the Canary Islands area to scrub, to forget about, some LM mark tracking that was to take place on the West Coast in the next several hours. Clouds apparently obscure the area that was to be observed in a pass across either California or the Western United States. The flight director Glynn Lunney has gone around the room and gotten a very thorough status report from each area, from each console, in the room and other than that, we are witnessing one of the longer scheduled sleep periods of the flight. I show the commander of the Apollo 7, Wally Schirra, and Walt Cunningham are scheduled here for an 11 hour rest sleep period. Walt Cunningham has just talked to us briefly and rather sleepily and probably will drowse on back to sleep. He woke up, had a drink of water, and talked a bit on the last pass. Here is some tape from that pass.

This is Apollo Control Houston 47 hours 40 minutes. We are about to acquire through the ship Huntsville parked off the California coast and we'll monitor that conversation when and if it develops. For your information our orbit this morning is 120 by 155 nautical miles. 120 by 155 miles. And for those keeping precise times of the starts of revolutions, the next Cape crossing time will be at an elapsed time of 47 hours, 54 minutes, 32 seconds. That will be the start of the 31st revolution. Here's the pass.

This is Apollo Control, Houston; 48 hours, 04 minutes into the flight. We are out at the far end of the ship Vanguard's area of acquisition and we will probably have no more contact for this pass. This pass did bring us a very complete summary of the crew status on board and among the things we heard was that Donn Eisele got 7 solid hours, as Walt Cunningham described them, of sleep. Cunningham said he had 6 hours and he reported that Schirra was still sleeping and he was still sleeping. We don't know precisely how long Wally Schirra has been asleep. Cunningham also reported some improvement in the - in what was beginning to be described yesterday as sick bay. Schirra's cold is better he said before he went to sleep, and he felt much better after taking a decongestant tablet last night before - Walt Cunningham took one before he went to sleep. At 48 hours and 05 minutes into the flight, that is our situation.
