Mike Collins (CAPCOM)

Apollo 8, Houston. Over.

Mike Collins (CAPCOM)

Just checking in with you after about a 45 minute quiet break. Say, we notice on your high-gain antenna, if you like, you can get a little bit more use out of it by switching to it from OMNI when you have a yaw angle of 90 degrees and a pitch angle of minus 45 degrees. We are noticing that you are staying an extra 10 minutes on the OMNI, which is fine; but you could get more use out of the high gain if you use that procedure. Over.

Frank Borman (CDR)

Okay, thank you. It's a lot simpler for us, as long as the OMNI isn't working. We've got it all wrapped up here on the eight ball with the roll … pointing to an OMNI number. We just switch it; it makes it a lot easier, if it is not bothering you.

Mike Collins (CAPCOM)

Okay. That is fine. We are presently happy with the COMM, Frank. We are just trying to be helpful.

Frank Borman (CDR)

Thank you very much. It's unusual that Mike Collins tries to be helpful, but nevertheless, thank you very much.

Mike Collins (CAPCOM)

Good; aerospace first, Frank.

Frank Borman (CDR)

Say hello to Howard Tindall for us, will you? His procedure seemed to be working.

Frank Borman (CDR)

I hope that you have got everybody looking this thing over very carefully. One thing we want is a perfect spacecraft before we consider the LOI burn.

Mike Collins (CAPCOM)

Apollo 8, Houston. We concur, and we are doing that.

Frank Borman (CDR)

Houston, Apollo 8. The water is in the process of being chlorinated at this time.

Mike Collins (CAPCOM)

Roger. Understand you're chlorinating the water at this time.

Mike Collins (CAPCOM)

Apollo 8, Houston. Over.

Mike Collins (CAPCOM)

At your convenience, we would like the readout of your service module RCS propellant quantities. We haven't gotten one of those so far this flight.

Frank Borman (CDR)

Alright. Stand by. We are just about to—need to change the antenna. I'll give them to you.

Frank Borman (CDR)

Houston, Apollo 8. How do you read?

Frank Borman (CDR)

Okay. A, service module A, you ready?

Frank Borman (CDR)

The temperature is about 111, the helium pressure—Do you just want the quantity, or do you want the whole works?

Mike Collins (CAPCOM)

Well, if you are reading, give us the whole works.

Frank Borman (CDR)

Okay. The helium pressure is about 37, the manifold is 182, and the quantity is reading 80. B has got the temperature about 112, the helium pressure about 36.5, the fuel pressure 180, and the quantity about 77. C has got the temperature of 140—incidentally, those other temperatures should have been 120 instead of 110; I was looking at the wrong calibration here. The pressure is 37, the manifold pressure is about 182, and the quantity is 80. Temperature on D is 115, pressure is 37, the manifold pressure is 181, and the quantity is about 83.

Mike Collins (CAPCOM)

Roger, Frank. I read you loud and clear. On the temperatures, quad A and B should both be 120. Roger.

Frank Borman (CDR)

I will trade all of that good information for a readout of the actual quantities. If you will give us a minute, we will go ahead and plot them up, Mike.

Mike Collins (CAPCOM)

Roger. We will stand by until we get them for you.

Mike Collins (CAPCOM)

Apollo 8, Houston. I have your service module RCS quantities available. Over.

Mike Collins (CAPCOM)

Okay. I have them both in percent and pounds; I'll give you both numbers. The pounds are slightly more accurate for plotting on your chart. Quad A 72 percent, 219 pounds; quad B 76 percent, 233 pounds; quad C 70 —

Frank Borman (CDR)

Take it a little slower, Mike; whoa, whoa, whoa whoa.

Frank Borman (CDR)

Slow up. We just got quad A plotted. They are on separate charts.

Mike Collins (CAPCOM)

Quad B 76 percent, 233 pounds.

Mike Collins (CAPCOM)

Seventy-six percent, 231 pounds.

Mike Collins (CAPCOM)

Seventy-six percent, 229 pounds.

Frank Borman (CDR)

Would you give us the O2 and H2 as long as we are plotting?

Mike Collins (CAPCOM)

Roger. Stand by for O2 and H2.

Mike Collins (CAPCOM)

Apollo 8, Houston. We have got those numbers in a percent. We are going to switch them over to pounds, and in the meantime, we are going to be changing our ground antenna in about another 2-1/2 minutes. You can expect a COMM glitch. Over.
