Ken Mattingly

Okay. You ready to press on?

Ken Mattingly

Okay. Just reminded we owe somebody a BAT B voltage.

Jack Swigert (CMP)

Okay, another volts and amps coming up.

Ken Mattingly

All right. Thank you. And this left us in P52 with two marks, and we'll go ahead and torque the NOUN 93s.

Jack Swigert (CMP)

Okay. … torque the NOUN 93s, after the two marks.

Ken Mattingly

Okay. So that gives us a good platform. Now the LM will maneuver to the jettison attitude, and the only thing of significance here is that you want to watch to make sure that the path they choose to go to the jettison attitude avoids gimbal lock on your own platform.

Jack Swigert (CMP)

Okay. The LM maneuvers to the jettison attitude and I just monitor the maneuver and yell at Jim if he gets near a gimbal lock.

Ken Mattingly

That's affirmed. Okay, and then the LM will go to a MAX deadband attitude hold in the jettison attitude.

Jack Swigert (CMP)

Okay. The LM goes to MAX deadband attitude hold.

Ken Mattingly

Okay. Now we're ready to go back to work. The next thing we'll do is to continue to powerup procedures. Do you have any further questions on that alinement, Jack?

Jack Swigert (CMP)

No. No. I think—I think it's all self-explanatory now.

Ken Mattingly

Okay. The one thing that everybody would like for you to understand is we certainly don't insist on using the Moon and the Earth; if you find you have good stars, why use them. However, this alinement is more than adequate to give us a good guided entry.

Jack Swigert (CMP)

Okay. If I get a set of good stars, do I start right out to a basic P51 and a P52 option 1?

Ken Mattingly

That's affirmative.

Ken Mattingly

Okay. Now, we're ready to go to work on panel 275. And it starts with a circuit breaker MAIN A —

Jack Swigert (CMP)

Wait—wait just a minute. Wait just a minute. I owe you some volts and amps.

Jack Swigert (CMP)

Okay. Volts are 39.4, amps, 1.25.

Ken Mattingly

Okay. I thought maybe, your meter was stuck before.

Ken Mattingly

All right. You ready to go back to 275? Have a circuit breaker MAIN A, BAT BUS A, closed.

Jack Swigert (CMP)

CB MAIN A, BAT BUS A, closed.

Ken Mattingly

That's correct. And circuit breaker MAIN B, BAT C, closed.

Jack Swigert (CMP)

CB MAIN Baker, BAT Charlie, closed.

Ken Mattingly

Okay. That's correct. Now we're up to EI minus 1 plus 30. And at this time, we're going to proceed with the closeout and hatch installation.

Jack Swigert (CMP)

Okay. Closeout and hatch installation at EI minus 01:30.

Ken Mattingly

That's right, Jack, and we're going to close the LM hatch, and we'll make the dump valve in the LM hatch closed.

Jack Swigert (CMP)

Understand you're going to close the dump valve, now on the LM hatch, right?

Jack Swigert (CMP)

Okay. This is a change from what we had understood previously.

Jack Swigert (CMP)

I'm—Personally, I'm happy to see it, but that's good.

Ken Mattingly

Okay. That's one vote on your side. Okay; and we're going to go ahead and do the—use the decal to perform the hatch installation, and we'll start on the hatch integrity check.

Jack Swigert (CMP)

Okay. Per the decal, perform the hatch installation and start on the hatch integrity check.

Jack Swigert (CMP)

Okay, Ken. One thing I think that—I don't know whether anybody—the decal don't take into account the fact that we still have the umbilicals connected. At what point in time should they be removed?

Ken Mattingly

Okay, Jack. That doesn't matter. We're going to be separating the tunnel upstream of those umbilicals, and you can leave them right there.

Jack Swigert (CMP)

Okay. Does it make any difference if we disengage—the LM—We have pulled the circuit breakers LM POWER-1 and -2, so if we choose to disconnect these umbilicals, there's no harm, right?

Ken Mattingly

That's right. No sweat. John Aaron's just saying that they may be hot. He's checking on it, so how about holding a decision on that and let me come back to you?

Ken Mattingly

Okay. And let me tell you what we're going to do since we told you a different story this afternoon on this tunnel. We're actually going to vent the tunnel down so that we end up with about 1-1/2 to 2 psi absolute in the tunnel. And this will give us a DELTA-P of 3. So we'll do our hatch integrity check at the same time we're venting the tunnel down.

Ken Mattingly

Okay. Now let me give you some plumbing switches here. Let's take the SURGE TANK OXYGEN valve to ON.

Ken Mattingly

All right. Take the MAIN REGs, two, OPEN.

Jack Swigert (CMP)

MAIN REGs, two, to OPEN.

Ken Mattingly

Okay. And the WATER AND GLYCOL TANK PRESSURE, the PRESSURE valve and the RELIEF valve to BOTH.

Jack Swigert (CMP)

Okay, WATER AND GLYCOL TANKS PRESSURE and RELIEF valve to BOTH.

Expand selection up Contract selection down Close
Ken Mattingly

That's correct. And EMERGENCY CABIN PRESSURE valve to BOTH.

Jack Swigert (CMP)

EMERGENCY CABIN PRESSURE to BOTH.

Ken Mattingly

That's correct; and the SUIT DEMAND REGs to BOTH.

Jack Swigert (CMP)

SUIT DEMAND REGs to BOTH.

Ken Mattingly

That's correct. Okay, now we're going to panel 5: circuit breaker ECS TRANSDUCERs, PRESSURE GROUP 1 and 2, MAIN A and MAIN B. That's four circuit breakers, closed.

Jack Swigert (CMP)

ECS TRANSDUCERs, GROUP 1 and 2, MAIN A and MAIN B, four, to close.

Ken Mattingly

That's correct. Okay, now. Circuit breaker ECS TRANSDUCER, TEMPERATURE, MAIN A and MAIN B, that's two of them, closed.

Jack Swigert (CMP)

CB ECS TRANSDUCER, TEMPERATURE, MAIN A and MAIN B, closed.

Ken Mattingly

That's correct. On panel 4: PRIMARY ECS GLYCOL PUMPS, one, to AC 1.

Jack Swigert (CMP)

Primary ECS GLYCOL PUMPS to 1, AC1.

Ken Mattingly

That's correct. Okay, then we'll finish going back to the tunnel vent, and verify the LM/CM DELTA-P and make sure it's been holding pressure. And we'll come back again and rehash all of the hatch integrity check and tunnel vent procedures with you. The next thing I want to read off is the EI minus 1 plus 20. We'll go to panel 7: BMAG number 1 POWER to WARM UP.

Jack Swigert (CMP)

BMAG number 1 POWER to WARM UP.

Ken Mattingly

That's correct. Then at EI minus 1 plus 10, we'll perform SCS powerup per checklist, page G/2-4.

Jack Swigert (CMP)

Okay. Perform SCS powerup per G&C checklist, page 2-4.

Ken Mattingly

That's correct. Okay, on panel 4: SUIT COMPRESSOR NUMBER 2 to AC1.

Jack Swigert (CMP)

SUIT COMPRESSOR 2 to IC1.

Ken Mattingly

That's correct. SPACECRAFT CONTROL to SCS.

Jack Swigert (CMP)

SPACECRAFT CONTROL to SCS.

Ken Mattingly

Okay. And your MANUAL ATTITUDE switches, as you desire. We're coming up on jettison of the LM, so that's just like separation.

Ken Mattingly

Okay. And we'll do a GDC aline.

Jack Swigert (CMP)

Okay. Perform a GDC aline.

Ken Mattingly

Okay. On panel 8: ROTATION CONTROL POWER, DIRECT, 1 and 2, MAIN A/MAIN B.

Jack Swigert (CMP)

Okay. These are circuit breakers, ROTATION CONTROL POWER, DIRECT, 1 and 2, MAIN A and MAIN B, closed.

Ken Mattingly

Okay, Jack. I was thinking switch. Let me verify that's a circuit breaker, too. I think we have to get both of them.

Jack Swigert (CMP)

Okay, there's those four circuit breakers over there, Ken. When you said panel 8, that's what I thought you were talking about. I don't think the circuit breakers are out right now, but why don't we just put—verify the circuit breakers and put the switches to MAIN A/MAIN B.

Ken Mattingly

Okay, that's correct, Jack. Okay, at EI minus 1 hour, we're going to be doing the LM jettison; so just prior to that, we want to do a P47.

Jack Swigert (CMP)

Okay, say at about 1 minute prior to LM jettison, huh?

Ken Mattingly

Yes, just something that's comfortable for you.

Ken Mattingly

All right, after we've? done that, we want to get panel 8, SEQUENTIAL, PYRO ARM, two of them, ON.

Jack Swigert (CMP)

Okay. I get a GO from MSFN for this?

Ken Mattingly

Okay, John says we can watch it.

Ken Mattingly

All right; the next thing is CSM/LM FINAL SEP, two of them, ON, up.

Jack Swigert (CMP)

CSM/LM FINAL SEP, two, ON.

Ken Mattingly

That's correct. Now we're going back to panel 8, and it's SEQUENTIAL, PYRO ARM, two of them, to SAFE.

Jack Swigert (CMP)

Okay. SEQ PYRO ARM, two, to SAFE.

Ken Mattingly

That's correct, and go back to P00.

Ken Mattingly

All right. And now it's time to configure for single ring.

Jack Swigert (CMP)

Okay. Configure for single ring RCS.

Ken Mattingly

That's right, and since you're still an hour from EI, I guess it wouldn't hurt to use MINIMUM IMPULSE or something like that rather than the DAP, at least not until you get closer down. We'll have the DAP loads for you later.

Ken Mattingly

Okay. And as soon as you've gotten yourself all set up with a good control mode, you want to maneuver to the entry attitude.

Jack Swigert (CMP)

Maneuver to entry attitude per the pad.

Ken Mattingly

That's correct. And we show EI minus 55, which really means when you get to the entry attitude, we have a sextant star check for you. And that will be on the pad.

Jack Swigert (CMP)

Okay. Perform a sextant star check.

Ken Mattingly

Okay. And I want to remind you to park the optics at 90 degrees of shaft.

Jack Swigert (CMP)

Okay. Say again why, Ken. I didn't understand that.
