Jack Swigert (CMP)

They were two brand new fresh ones.

Jack Lousma (CAPCOM)

Aquarius, Houston. In regards to the CO2 canisters, by the way the PCO2 is reading 1.6 down here now. We expect that we can get 6 more hours out of the two canisters that we have there—6 hours at least. However, at 112 hours, when we've got several people up, we're going to rig up two more and we have the new simplified procedure for doing this. However, in the meantime, should we need to have a canister change, we plan to switch to the LM primary canister. Over.

Jack Swigert (CMP)

Okay. Copy that, Jack.

Jack Lousma (CAPCOM)

And, Aquarius, how's your PTC holding up?

Jack Swigert (CMP)

Well, we got a little bit off Jack. The—It starts high in the LMP's window and goes low in the CDR window.

Jack Swigert (CMP)

So we've got a little bit of a wobble on it. Of course, the command module venting doesn't help, either.

Jack Swigert (CMP)

Jack, in reference to your question about the PTC, on this last complete revolution, the Sun first appeared in the very top right corner of the LMP window, passed over the CDR window, and was visible through the overhead window, and now the Moon is—came pretty well through the center of both windows this last time.

Jack Lousma (CAPCOM)

Okay. Thank you, Jack. Copying that.

Jack Lousma (CAPCOM)

Aquarius, Houston. We'd like to get a little better idea of how PTC is going. So, what we'd like for you to do is what we did last time. That is to give us a reading on the center of the Earth and the center of the Moon on the—LPD.

Jack Swigert (CMP)

On the LPD. Okay, It's shifted. Let's see, the Moon's gone by and the Earth didn't come into the LPD last time.

Jack Lousma (CAPCOM)

Okay. But when it goes by the plane of the LPD, tell us where it was. Okay?

Jack Swigert (CMP)

Okay, Jack. This pass, the Earth came into view at the top left-hand corner of the LMP's window and was going down. However, when it passed it wasn't as high up as the last pass. It did pass into view at the CDR window, but too high up to get an LPD reading.

Jack Lousma (CAPCOM)

Roger. Understand it went high in both windows then.

Jack Swigert (CMP)

Yes, last time it wasn't even visible in the CDR's window; this time it was visible if you squatted down, but too high up to get an LPD reading.

Jack Lousma (CAPCOM)

Okay, Jack. That's good. Thank you.

Jack Swigert (CMP)

Okay, Houston; Aquarius.

Jack Swigert (CMP)

Okay. The moon came into view at the middle of the LMP's window, passed through the CDR's window at an LPD of 5 degrees.

Jack Swigert (CMP)

Okay, Jack. On this pass, the Earth came into the view at the top part of the LMP's window, and we got an LPD angle on it as it passed through the CDR's window of a minus 4 degrees.

Jack Lousma (CAPCOM)

Okay. A minus 4. Thank you, Jack —

Jack Swigert (CMP)

It's—it's above the—Okay. Are you familiar with the minus 4 being halfway through the sky part, huh?

Jack Swigert (CMP)

Okay, Houston; Aquarius.

Jack Swigert (CMP)

Okay. On this pass, the Moon came into view at the top part of the LMP's window, came across higher. Jim estimates the LPD angle at a minus 15 degrees.

Jack Lousma (CAPCOM)

Okay. A minus 15 on the moon, and sounds like it's set up pretty well.

Jack Swigert (CMP)

Everybody's happy with it down there?

Jack Lousma (CAPCOM)

Aquarius, it's a little too early to tell exactly how the PTC is going. We'd like to get a few more points, so keep reading them off, and we're still looking for that SUPERCRIT to go anytime.

Unidentified crew member

Okay.

Jim Lovell (CDR)

The Earth was just fairly high in the LMP's window and across the 14-degree LPD line.

Jack Lousma (CAPCOM)

Okay, Skipper; 14 degrees. Thank you.

Jim Lovell (CDR)

The Moon went by the LPD at 6 degrees, plus 6 degrees.

Jack Lousma (CAPCOM)

Okay. Earth at plus 6. Thank you.

Jim Lovell (CDR)

That's the Moon, the Moon.

Jack Lousma (CAPCOM)

Okay. The Moon. Thank you.

Jim Lovell (CDR)

The Moon passed by at a minus 8 degrees on the LPD. No, that's the Earth. The Earth passed by at a minus 8 degrees.

Jack Lousma (CAPCOM)

Okay. The Moon went by at a minus 8 degrees.
