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.
