Spacelog Apollo 13

Houston, Aquarius.

Go ahead, Aquarius.

Our REPRESS package pressure is 820.

Aquarius, Houston.

Go ahead, Houston.

Jim, could you switch your BIOMED switch to the position opposite to where it is now? We are getting a subcarrier, but no data. Over.

Now you know, Houston, I don't have BIOMED on.

Okay. And we have a small addition to the procedure that was read up to you earlier, which involves power transfer from the LM to the CSM.

Stand by 1.

Okay.

Okay, Houston. Go ahead.

Okay. At the end of the procedure, after the step BAT 5 and 6, OFF, add the following: circuit breakers, panels—panels 11 and 16, ASCENT ECA CONTROL, both open. Over.

Okay. After the step BAT 5 and 6, OFF, step 3 will be circuit breakers panels 11 and 16 ASCENT ECA CONTROL, both open.

That's correct, Jim. And this is to guard against a single-point failure that—a remote possibility that would preclude you from getting the batteries back on.

Roger.

Houston, Aquarius.

Go ahead, Jim.

Okay. We just had a battery warning … Battery 2.

Stand by, Jim. The COMM's no good here right now.

Houston, Aquarius. How do you read now?

Go ahead. Loud and clear.

Okay. We just had a battery warning MASTER ALARM, and it looks like it's battery 2.

Roger.

Roger, Houston—This is Houston. Could you close the POWER AMP circuit breaker, and we'll get some high bit rate?

Roger.

It's closed.

Okay. And we need high bit rate.

Are you picking it up, Houston?

Roger. And we want to open the BAL LOAD CROSS TIE on panel 16. Over.

Say again.

Open the BAL LOAD CROSS TIE breaker on panel 16. Over.

Open BALANCE LOAD CROSS TIE breaker on 16. Roger.

That's affirm.

It's open.

If you're getting high bit data, we could do an OFF/RESET and go back on on battery 2. We're standing by for that.

Okay. Could you turn off battery 2, and leave it off and let us look at it?

Say again. You want us to turn off battery 2, and leave it off until you look at it?

That's affirmative.

Okay. Battery 2 coming off the line.

Okay, Aquarius. So you want to stay in this configuration for awhile, and let's look at the battery.

Roger. We'll stay in this configuration.

Want to close the BAL LOADS circuit breaker back now.

13, Houston. We want to close the BAL LOADS circuit breaker on panel 16 now, again.

We have it closed; the closed—BALANCE LOADS circuit breaker is closed.

Roger.

Aquarius, Houston. Request RANGE FUNCTIONS switch to RANGE …

Go ahead, Houston.

Jim, on the battery problem, we have determined that it is not overcurrent or reverse current. We suspect it's over-temp, but don't know for sure, so we're going to watch it for awhile.

Aquarius, Houston.

Go ahead, Houston.

Jim, Charlie has some procedures to read up for you here; I think you'll need your activation checklist, if it's handy.

Aquarius, that's the contingency checklist.

Okay. I'll just—Okay. Stand by, Charlie.

Okay, Charlie. I've got the contingency checklist, and standing by.

Okay, Jim. We'd like you to turn to page—page 24, which is the “30-Minute Activation,” and this is going to be a procedure for the mid-course burn that we got coming up at 105 with the AGS up. Over.

Roger. On the midcourse at 105, and I'm on page 24.

Okay; “30-Minute Activation,” omit steps 1, 2, and 3; perform step 4, “RCS system A/B-2.” Over.

Roger. Omit steps 1, 2, and 3; perform step 4.

Roger. And on the “EPS Activation,” same page, perform step 1; and in step 2, perform line number—line number 6, “EPS DISPLAY-CLOSE.” Over.

Okay. On “EPS Activation,” perform step 1, and perform step 2, line 6 only; is that correct?

That's affirmative, Jim. The rest of the stuff is already closed at this time, so that's all we'll have to do is close the EPS DISPLAY breaker.

Okay.

All right. Turn to page 25. On page 25, omit step 3; perform step 4. On step 4, last line, scratch “CB(16) EPS: INVERTER 2, closed.” Over.

Roger. Omit step 3; perform step 4, except for the last line. Circuit breaker 16, EPS INVERTER 2, closed.

Roger. That's correct. On step 5, perform step 5. Under “Primary Glycol Loop Activation,” step 1, line 1, “CB(16) ECS: DISPLAY—CLOSE.” That's a crew option; you can have it if you want to. Omit the rest of step 1 and step 2. Perform step 3. Over.

Okay. On primary glycol loop activation, crew option on step 1, first line; the rest of it we'll omit. Step 2, we'll omit, and we'll do step 3.

That's affirmative, Jim, with the following DELTAs on step 3, and if you'll turn to page 26, I'll give you the DELTAs on the activation circuit breaker list. Over.

Okay. I'm there.

Roger. On line 1, correction, row 1, under AC BUS A: TAPE RECORDER should be open; DECA GIMBAL, open. All the other ones as shown on the page. Over.

Okay. On row 1, AC BUS A: TAPE RECORDER and DECA GIMBAL will be open. All the rest as shown.

Roger. And we don't know the status of your windows. If you—During this burn, we're going to have to look out the forward window to get the alinement with the COAS, so you might need the commander window heater and you can, of course, use that breaker if needed, since we do have the AC power. On row 2—Go ahead. Over.

I don't think we'll need it, Charlie.

Okay; fine, Jim. On row 2, under RCS SYSTEM A: ASCENT FEED 2 and ASCENT FEED 1 should be open. Under FLIGHT DISPLAYS: MISSION TIMER should be open; GASTA, open; ORDEAL, open. Under AC BUS A: GASTA, open. The rest are as shown on the page. Over.

Okay. On row 2, we're going to open up ASCENT FEED 2 and ASCENT FEED 1 under RCS SYSTEM A. We're going to open up the MISSION TIMER, and FLIGHT DISPLAYS: the GASTA and the ORDEAL; and the AC BUS A: the GASTA.

That's affirmative. Okay. Row 3, under PROPELLANT: DESCENT HELIUM REG/VENT should be open. Under HEATERS: RENDEZVOUS RADAR STANDBY, open; LANDING RADAR, open. Under STAB/CONTROL: ATCA (PGNS), open. Under ED and LIGHTING: all four open. Over.

Okay. Row 3, under PROPELLANT—propulsion: the DESCENT HELIUM REG/VENT will be open: the STANDBY RENDEZVOUS HEATER will be open and the LANDING RADAR HEATER circuit breaker will be open. I just changed antennas; and, keeping on down the line, ATCA PGNS will be open and the last four circuit breakers, two under ED and two under LIGHTING, will be open.

That's affirmative. Okay. Under row 4, under ECS: GLYCOL PUMP AUTO TRANSFER, close. Under COMM: UP DATA LINK, open; VHF B and VHF A should be open. Under PGNS: LGC/DSKY, open; IMU OPERATE, open. Over.

Okay. Under row 4, the AUTO TRANSFER will be close. UPDATA LINK, open; VHF A and B, open; DSKY, open; and IMU OPERATE, open.

That's affirm. On the last row, the only DELTA is under the CROSS TIE BUS and it should be open. Over.

Say that again, Charlie.

Okay. Under the last row, under EPS is the only DELTA and that is under the CROSS TIE BUS. It should go open. Over.

Roger. The CROSS TIE BUS should go open.

That's affirm. Going on to page 27, Activation, panel 16. Under RCS SYSTEM Bravo: ASCENT FEED 1, ASCENT FEED 2 should be open. Under PROPULSION: PQGS should be open; ASCENT HELIUM REG, open. Over.

Okay. Line 1, on panel 16, ASCENT FEEDs 1 and 2 will be open. And the PQGS will be open, and the ASCENT HELIUM REG will be open.

That's affirmative. On the next three rows, we only get the nine DELTAs, so I'll go through the next three rows completely and then you can read those back. Under LIGHTING —

Okay.

Under LIGHTING; FLOOD, open; TRACK, open. Under ED LOGIC—Correction, under ED: LOGIC, open. Under STAB/CONTROL: DESCENT ENGINE OVERRIDE, open. Under ECS: SUIT FLOW CONTROL, open. Under row 3, COMM: DISPLAY, open; VHF A TRANSMITTER, open; VHF B RECEIVER, open. Under ECS: DISPLAY, that's crew option. Last row, under EPS: INVERTER 2, open. Over.

Okay. On the last three rows, we have FLOOD and TRACK circuit breakers, row 2, open; LOGIC POWER B, open; DESCENT ENGINE OVERRIDE, open; SUIT FLOW CONTROL, open. On the third row—row, DISPLAY, open; VHF A and—VHF—VHF A TRANSMITTER, open; VHF B RECEIVER, open. And under ECS: we have DISPLAY, open, at crew option. And the last one, INVERTER 2 under EPS, will be open.

Roger. That's a good readback. Under that ECS DISPLAY, it shows it closed. If, with it closed, you can have some readout of—onboard readout of your ECS system—draws a lot less than a half amp so it's up to you whether you want it or not. Okay, on page 28.

Roger.

On page 28, step—perform step 4 with the following changes in the warning light status. Under the warning lights, you will probably—you will have ASCENT PRESSURE and an LGC light. Scratch “RCS A and RCS B REG.” Under caution lights, you'll have a PRE AMPS light. Over.

Roger. Under warning, we'll have ASCENT PRESSURE and LGC; and under caution, we'll have a PRE AMP.
