1966-03-16, 8:33 pm This is Gemini Control, Houston. We have been in touch with the spacecraft over the past few minutes, a detailed briefing other than the numbers which they received earlier on the retro positions and their retro commands passed along. We acquired at 9 hours and 44 minutes into the flight. Actually the TM acquisition, the voice conversation picked up a couple of minutes later. The crew sounds quite relaxed coming into this retrofire maneuver. Among other things they were advised to drink some water before their retrofire maneuver. It was also suggested they drink some water after retrofire on their way down to the landing point. The surgeon also has suggested that each of them take a tablet of merazine. This is a tablet to avoid motion sickness. The reason being while the wave height in the landing area is only three feet, it's choppy, and they suspect it might cause them to be a little seasick once down on the water. The crew has confirmed they have completed their pre-retro checklist and they a further medical suggestion was that if they do elect to leave the spacecraft, the suggestion is to take the medical kit along just in case. Meanwhile the C-54, whose call sign has been passed along to them, is nearing the area, the impact, the landing area. It has on board three pararescue men who will leap into the water once they have the spacecraft in sight. They will have with them a flotation collar which they will affix about the spacecraft. At nine hours 53 minutes into the flight, this is Gemini Control, Houston.
Communications via Houston, Texas, US
009:52:24 Houston CC: Roger. Go.
009:53:37 Armstrong: Roger. We understand.
009:53:39 Houston CC: Gemini VIII, I have some new rescue data for you. You ready to copy?
009:53:44 Armstrong: Go ahead.
009:53:45 Houston CC: Roger. Naha Rescue 1 will be on station at splashdown with parajumpers and a flotation collar. The USS Mason will be on site about 3 hours after splash. And a reminder that Core 86 is for latitude and 87 is for longitude for your check between 80 and 50K.
009:54:14 Armstrong: Okay. [Garble].
009:54:15 Houston CC: And I have a backup yaw star for you for Retrofire minus 4 minutes. Sirius will be 4 degrees right of track.
009:54:27 Armstrong: Roger.
009:54:31 Houston CC: And we'll be counting in the blind through Kano for your Retrofire.
009:54:52 Houston CC: Gemini VIII, Houston. Do you copy?
009:54:59 Armstrong: Roger.
009:55:04 Houston CC: Houston standing by.
Transcription break.
009:56:15 Houston CC: Gemini VIII, Houston. There will be no contact with us after Retrofire. We might pick you up through the CSQ after blackout. We'll be standlng by for HF after splash.
009:56:28 Armstrong: Roger. Understand.
009:58:38 Houston CC: Gemini VIII, Houston CapCom. We've got one more minute to LOS. We'll be standing by to hear your TR minus 1 check.
Transcription break.
010:00:29 Houston CC: Ascension LOS.
Transcription break.
010:01:52 Scott: Okay. We've not had this yet.
010:01:54 Armstrong: We don't. Just let it stay there.
Scott: [Garble.]
010:01:57 Armstrong: Okay. I'm going to go RCS now and OAMS Off.
010:01:58 Scott: Okay. [Garble].
010:02:07 Armstrong: I'm in Rate Command ACME.
010:02:09 Scott: Okay.
010:02:11 Armstrong: Let's have a time hack here.
010:02:16 Scott: Okay.
010:02:17 Armstrong: Okay. Now.
010:02:23 Scott: 2:23:04.
010:02:24 Armstrong: Good.
010:02:57 Houston CC: Gemini VIII, Houston CapCom. Verify your TR minus 4:16 complete and we are standing by for you Sep Adapt.
010:03:06 Armstrong: Roger. It's complete.
010:03:08 Houston CC: Roger.
010:03:11 Armstrong: We didn't get a TR minus 2:56 signal, but our TR is in sync.
010:03:17 Houston CC: Roger.
010:03:23 Scott: Okay. Coming around to 1 minute.
010:03:26 Armstrong: Okay.
010:03:40 Scott: Okay.
010:03:41 Houston CC: Stand by for a Mark at 1 minute. Stand by 60 seconds - 60 seconds.
010:03:43 Armstrong: Roger. We have Sep OAMS, Sep Elect and Sep Adapt.
010:04:07 Houston CC: Okay. 41 seconds.
010:04:09 Armstrong: Okay.
010:04:14 Houston CC: 30 seconds.
010:04:19 Scott: I'm on Auto Retro.
010:04:23 Armstrong: Okay. Don't do that yet.
010:04:24 Armstrong: Retro Rocket Squibs (4) - Arm.
010:04:25 Scott: 1, 2, 3, 4, Light.
010:04:28 Armstrong: Okay.
010:04:34 Houston CC: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1...
010:04:47 Houston CC: Retrofire.
010:04:51 Scott: Props Off.
010:04:52 Armstrong: Hang in there.
010:05:11 Scott: Okay. Four retros fired in Auto Retrofire and 292, aft 000 and 114 down.
010:05:15 Houston CC: Roger. Auto Retros. Four retros.
010:05:17 Armstrong: [Garble] aft 000 and 114 down.
010:05:22 Houston CC: Say again the IVIs.
010:05:26 Scott: That's great.
010:05:33 Armstrong: Okay. Will you...
010:05:35 Scott: Up 1.3.
010:05:36 Houston CC: Gemini VIII, Houston. Say again your IVIs.
010:05:39 Armstrong: Okay. Check Retro.
010:05:40 Scott: Okay. Check Retro.
010:05:42 Armstrong: Go ahead. Start.
010:05:45 Scott: Retro, check.
010:05:47 Scott: No change in it.
010:05:49 Armstrong: No changes on the IVIs.
010:05:55 Armstrong: Got one ACME Off on the Pulse.
1966-03-16, 8:47 pm This is Gemini Control, Houston. The pilots were counted down in the blind via the Kano Station, and Neil Armstrong, while he said nothing leading up to the point of retrofire, came back with a very reassuring, "We have all four retros; all four have fired". A cheer went up here in the Control Center, and I'm sure everyone can understand why. The contact from here is through the Kano, Nigeria station. Armstrong, after the maneuver, went on to relate that everything was in a stable condition and seemed to be proceeding satisfactorily. We want to emphasize again that there is practically no communication expected now for some time. We are going to try to reach them via the Coastal Sentry Quebec on HF after they emerge from blackout, but that signal at best will be marginal, Probably our first authoritative information will come via one of those C-54 aircraft maneuvering in the area of east of Okinawa. This is Gemini Control, Houston.
