Apollo- Soyuz, as I lived it a half century ago Pt3
SON OF A
BITCH
Next on the
checklist of major events in the ASTP flight was the transposition and docking
required to extract the Docking Module (DM) from the S-IVB. The DM was the only piece of real spaceflight hardware constructed for the mission. It was needed because the atmospheres used in Soyuz and Apollo were very different. I'll go into it in far more detail in a later post.
The event took place away from the
best ground stations. In fact Mission Control only had communications off and
on for a few seconds. The crew, however, videotaped the entire event to
transmit later to the ground. The transposition and docking was shot with two cameras. One was the
same camera that was used during the boost to orbit and was focused on Stafford and Brand. The extraction of
DM was shot with a second camera directed through the rendezvous window. I was lucky enough to get a copy of the camera pointed at the crew which had a voice track. The conversation below was taken from that video. Stafford did not have a fun time
while flying the transposition and docking because the sunlight reflecting
outside was blotting out his Crew Optical Alignment Sight, (COAS).
The stand-off cross that would normally have been mounted on the Lunar Module, were now mounted on the docking module truss in the S-IVB stage. “Okay I’ve got
full bright on that COAS,” Stafford reported.
“It’s right out
there where he ought’a be” Brand quipped.
“Oh, what’re
we, in CMC AUTO?” Stafford checked, “hey Vance?”
“Okay,” Brand
replied reading from the checklist, “ENTER, plus-X, three seconds…”
“How did we
ever…(garbled)…” Stafford complained, “God damn, I can’t see my COAS… it’s so
bright I can’t see the COAS! Son of a bitch! Okay, we can close on him… let’s
get this…”
“Did ya’ do…”
Brand began, “plus-X three seconds?”
“Got it,”
Stafford replied quickly.
“Okay, I got
your DAC (Data Acquisition Camera) changed,” Brand reported calmly.
Stafford was
clearly flustered in the video, as he moves a great deal in his seat and
strains to see the COAS.
“Dick we’ve got
a problem,” Stafford reports sharply to CAPCOM Dick Truly, “it’s so bright in
that background I can’t see my COAS.”
Apollo,
however, was on the ratty edge between two ground stations and Houston
apparently did not hear Stafford’s report.
“COAS, or
target?” Slayton asked.
“COAS!”
Stafford answered.
“Huh.” Slayton
replied in a very mid-west Deke manner.
“Oh shit!”
Stafford growled with resignation. Then he changed gears and went back into mission commander mode, “How’re we doin’ on attitude?”
“Okay,” Brand
reported, “yer’ attitude and uh…”
“Somehow that’s
not lookin’ right… now,” Stafford mumbled.
“Okay, got the
DAC goin’…” Brand reported.
Highly
flustered by the fact that our planet’s nearest star may be about to throw a
monkey wrench into the rendezvous and docking of the one human who has done
more rendezvous and docking than any other human, Stafford began to go into
high bit-rate pilot mode.
“Okay… are we’re
supposed to go over that (garbled) some more, hey Dick, we’re off, to… get back
on to the computer, we’re not to the pitch attitude yet…” Stafford stammered in
one long breath.
“Okay,” Brand
replied calmly, “we’ll… do it again.”
“CMC in AUTO,”
Stafford called, “okay take it and we’re maneuverin’…”
“Okay,” Brand
said, “we should be.”
“(garbled) stopped
it earlier,” Stafford said with a calming sigh in his voice as his COAS comes
back into view.
Houston can be
heard in the background offering a time to LOS and some information on TV
settings which Stafford “rogered,” and then he gave a relieved call back to
Mission Control,
“And I finally
got the COAS back in, finally!”
I transcribed
all of that for you, the readers, for one very important reason: other than
that final COAS call, none of the above conversation appears in the official
NASA onboard voice transcript. When I first saw it on the raw video I thought
that it was very human and very Tom Stafford, but when researching the
transcripts for this text, it was simply missing. One may think that it was
because of the salty language involved, but there are other areas in the
transcript where the exact same curse words are used and they remain in the
transcript. Why this section is missing is for you, the reader, to ponder. My
own theory is that the transcriber took a potty break and left the tape
running.
Extraction of
the DM took place during a period of an hour and 51 minutes in which the Apollo
was out of communication with Mission Control. The process went smoothly. The
reason for the Apollo being out of range for such extended periods of time was
due to the fact that the Soyuz had a very limited orbital inclination onto
which it could be launched. That inclination was set up to allow the spacecraft
to fly over and land on Soviet territory. Meanwhile, U.S. spaceflights had been
planned from their earliest days to fly down the Eastern Test Range and orbit
much more near the Earth’s equator. Thus, the U.S. tracking stations were
established along that route, which was far south of most Soviet orbits. The
tracking range had been supplemented over the years with
communications-equipped ships and aircraft, yet there were still gaps. When a
more northerly inclination was taken for ASTP, there were large gaps in
communication and tracking.
Stafford, Brand
and Slayton spent the next day working to collapse their docking probe so it
could be properly stowed and doing an SPS burn to adjust their orbit. Likewise,
Leonov and Kubasov did an 18-second burn on the Soyuz in order to circularize
their orbit.
In addition to their burn the cosmonauts managed to repair their broken TV camera aboard Soyuz. Using band-aid type
adhesive strips from their medical kit they reportedly spliced
some broken wires and got the camera working again.
Meanwhile, I spent the day
with a spray can of window cleaner getting to know every window in the Civic
Center and thinking about those five men orbiting the
Earth. When your work is dull, the mind has to go
someplace- in my case it was Earth orbit.
