:16:08
Well, John.
I can certainly see it now.
:16:20
Beautiful. I gotta call Joe Gavin
about the budget.
:16:24
One more thing: Thermal shields.
:16:26
Costing us way too much weight
in the descent stage.
:16:31
You know, I don't think we need shields.
:16:34
Right, Frank. It's gonna be 250 degrees
in the sunlight...
:16:37
and minus 250 in the shade...
:16:39
but we don't need thermal shields.
:16:41
Sarcasm's really helpful, Jim.
:16:43
I just mean...
:16:44
maybe we can use something other than
the shielding that's been used before.
:16:56
It'll look kind of like that.
:16:58
Mylar film between layers of kapton...
: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.
