Apollo 11 re-enactment – Splashdown (July 24) – Mission audio & commentary

apollo_11_ocean_recovery Communications between Apollo 11 Mission Control and the crew in the Command-Service Module until separation and final splashdown (source: http://www.hq.nasa.gov/alsj/a11/a11transcript_pao.htm). Note times are Central Daylight Time (Houston, U.S.A.) and Ground Elapsed Time (GET); GET 00:00 was liftoff (2332 Australian Eastern Standard Time).

CAPCOM
Okay, Mike. Of course, this is in the event the G&N and the EMS quits and you have to fly the constant G, and what we’re trying to do is extend the constant G range from 1100 to 1500 miles.

We’ve run this procedure in the simulators and it works fine. The best way to go through it, just go through it and if you have any questions come back. But it’s the same lift vector UP until MAX G, and then lift vector DOWN and then modulate the lift vector until g dot goes to zero.

Okay, this procedure is essentially the same so far, and then hold g dot zero until you pass the retro elapsed time of V circular and then after you pass this retro elapsed time of V circular, roll to a gimbal angle of 45 degrees, and then hold this constant bank angle of 45 degrees until you’ve come to the retro elapsed time of drogues. Over.

SC
Okay, it sounds straight forward enough. Understand constant G backup procedure lift vector UP until MAX g and then lift vector,DOWN, then modulate until bank angle until g dot equals zero, then g dot equals zero until

SC
sub circular and then roll 45 degrees and hold until drogue time. Over.

CAPCOM
Hey, that’s mighty fine, Mike. That’s correct.

PAO
This is Apollo Control at 192 hours 2 minutes.

This will be first time in Apollo that crews have flown lift vector UP during reentry. Normally, lift vector is down. However, we want to extend the range by 215 miles so for a short period about a minute and 25 seconds during the blackout period the spacecraft will be flown with lift vector up. The computer program for that is number 65, up control.

Apollo 11 is now 25,301 nautical miles from Earth, velocity has increased to 12,263 feet per second.

Apollo 11 re-enactment – Pencils ready? Re-entry details

At Ground Elapsed Time (GET) 186:28 hours, Apollo Mission Control released the following details in relation to Columbia’s entry into the Earth’s atmosphere and landing in the Pacific Ocean (taken from the transcript at http://www.hq.nasa.gov/alsj/a11/a11transcript_pao.htm):

This is Apollo Control 186 hours 28 minutes Ground Elapsed Time.

8 hours 35 minutes to entry.

Crew of Columbia still asleep at this time. Some 2 and a half hours away from wakeup time at 189 hours Ground Elapsed Time.

Because of weather avoidance in the prime recovery zone in the mid-Pacific, southwest of Hawaii, it has been decided some time ago to shift the landing point – aiming point – some 215 nautical miles downrange from the pre-mission aiming point.

And all the numbers concerned with entry and post-entry events have been generated, and we shall forward them at this time.

Pencils ready?

  • Command Module-Service Module separation, 194:48:07 Ground Elapsed Time, 11:20:08 Central Daylight Time;
  • entry enterphase, that’s 400 000 feet above the Earth’s surface, Ground Elapsed Time 195:03:07, 11:35:08 Central Daylight Time;
  • begin blackout, 195:03:25 Ground Elapsed Time, 11:35:26 Central Daylight Time;
  • 05G, 195:03:35 GET, 11:35:36 CDT;
  • end of blackout, 195:06:56 GET, 11:38:57 CDT;
  • drogue parachutes deploy, 195:12:04 GET, 11:44:05 CDT;
  • main parachutes deploy, 195:12:52, 11:44:53 CDT;
  • touchdown, 195:17:49 GET, 11:49:50 CDT.
  • Maximum G-loading to be pulled during the entry phase will be 6.12G’s.
  • Entry velocity, that’s at entry enterphase of 400 000 feet, will be 36,194 feet per second.
  • Flight path angle, minus 6.5 degrees.
  • Aiming point location, 13 degrees 19 minutes north latitude, 169 degrees 09 minutes west longitude.

At 186 hours 32 minutes Ground Elapsed Time, this is Apollo Control.

Apollo 11 re-enactment – On the way home

apollo_11_photo_aldrin_outof_lm Man has been to the Moon, walked on it, slept on it and is now returning to Earth.

APOLLO 11 MISSION COMMENTARY    7-20-69     CDT 12:46  –  GET 100:14

PAO
This is Apollo Control at 100 hours, 14 minutes. We are now less than 2 minutes from reacquiring the spacecraft on the thirteenth revolution. When next we hear from them the lunar module should be undocked from the command and service module. We’re presently about 25 minutes away from the separation burn which will be performed by Mike Collins in the command module to give the LM and the CSM a separation distance after descent orbit insertion maneuver of about 2 miles.

We have some times on the upcoming evnts. The separation maneuver is scheduled to occur at a ground elapsed time of 100 hours, 39 minutes, 50 seconds, the descent orbit insertion maneuver which will be performed on the backside of the moon set for 101 hours, 36 minutes, 14 seconds, and the beginning of the powered descent at 102 hours, 33 minutes, 4 seconds.

We’re now 55 seconds from reacquiring Apollo 11 on the thirteenth revolution. During this revolution we will be doing the separation maneuver. We’ll also be giving the crew on the lunar module a GO-NO/GO for the descent orbit insertion maneuver. We’ll stand by now to reacquire the spacecraft. We have confirmation of acquisition of signal. We’ll stand by for a call to the Crew.

APOLLO 11 MISSION COMMENTARY    7-20-69     CDT 14:07  –  GET 101:35

PAO
This is Apollo Control at 101 hours, 35 minutes. We’re. now. less than one minute from the scheduled time for the descent orbit insertion maneuver performed by the lunar module on the backside of the moon.

Of course, we don’t have radio contact with the spacecraft. In mission control here normally maneuvers of that sort would be monitored on plot boards in front, and we have the boards set up there for the powered descent. To occur about 1/2 rev from now over landing site 1. Flight controllers standing around in little groups. Not much that we can do at this point until reacquiring spacecraft.

We’re now 20 minutes – or 20 seconds rather from ignition on the descent orbit insertion. It will be a 29.8 second burn of the 9800-pound thrust descent propulsion system. We should be burning at this time. The result of this maneuver will be to put the spacecraft into an orbit 57.2 by 8.5 nautical miles, and it would remain in that orbit until powered descent.

PAO
We should have a cut off by this time. That should have completed descent orbit insertion maneuver. We would expect to reacquire the command module first. Command module acquisition time is 102 hours, 14 minutes, 38 seconds. That will be just about 2 minutes prior to the time that we will have reacquired the lunar module.

The LM acquisition time is 102 hours, 16 minutes, 25 secomds. That is about 37 minutes, 20 seconds from now on the CSM at about a little less than 2 minutes longer than that for the LM.

At 101 hours, 37 minutes, this is Apollo Control, Houston

I’m at the foot of the ladder. The LM foot pads are only depressed in the surface about 1 or 2 inches. Although the surface appears to be very, very fine grained, as you get close to it. It’s almost like a powder. Now and then, it’s very fine.

I’m going to step off the LM now.

That’s one small step for a man. One giant leap for mankind.
