:17:00
with an outer layer of nickel foil.
:17:02
How thin is the mylar?
:17:04
- 1/8,000 of an inch.
- Oh, well.
:17:06
As long as it's good and sturdy.
:17:08
We'll use a couple dozen layers
all around.
:17:11
More where we need it...
by the thrusters.
:17:14
It'll do the job.
:17:17
Okay, well, we'll see
how it goes in testing.
:17:20
Now, hatches.
:17:22
As it stands,
we have two docking hatches.
:17:24
We can't afford the weight.
:17:26
I've been on the phone
with Owen at NASA...
:17:28
and John Healey at North American,
and we all agree.
:17:31
We're gonna go with just
the one docking hatch up top...
:17:33
and use a forward hatch for egress.
:17:35
That means when they return they'll
have to rendezvous and dock blind.
:17:39
We're gonna put a window up top
so the pilot can look up as he docks.
:17:42
Another window?
How much is that gonna weigh?
:17:44
I don't know. It's gotta be less
than a second docking hatch, right?
:17:48
That will require the astronaut
flying the LEM...
:17:50
to make a 90-degree change in axis.
:17:54
Left roll becomes left yaw.
:17:57
- But left yaw becomes right roll...
- Arnold.
:18:00
Astronauts are smart.
They'll figure it out.
:18:11
Apparently we're not done
with the hatches.
:18:13
I just got off the phone
with Pete Conrad.
:18:15
Because of the square backpacks, we're
gonna have to put in a square hatch.
:18:26
Did you like Ed swingin' around
like Tarzan yesterday?
:18:32
Yeah. Rope ladder's not gonna fly.
:18:34
No. I'll call
the configuration control board.
:18:38
We can put some rungs
right on the forward leg.
:18:44
Okay, one more thing. It's no longer
the Lunar Excursion Module any more.
:18:48
Everybody feels that "excursion" sounds
like it's gonna go out on a school trip.
:18:52
From now on it's just the Lunar Module.
:18:55
I'm still gonna call it the LEM
for short.
:18:57
John, you do whatever makes you happy.
