Spacelog Apollo 13

Okay. You ready to press on?

I'm ready.

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

Okay, another volts and amps coming up.

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

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

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.

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.

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

Okay. The LM goes to MAX deadband attitude hold.

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?

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

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.

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

That's affirmative.

Okay.

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

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

Okay. All right.

Okay. Volts are 39.4, amps, 1.25.

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

No (laughter).

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

CB MAIN A, BAT BUS A, closed.

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

CB MAIN Baker, BAT Charlie, closed.

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.

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

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.

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

That's correct.

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

That's correct.

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

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.

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

That's correct.

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?

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.

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?

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?

SURGE TANK O₂ to ON.

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

MAIN REGs, two, to OPEN.

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

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