you just can't purge particles in the interior in that these are
angles and trap volume~, but I would suspect that we had a very
low order of nitrogen gas within the vehicle that could come out.
Now it can come out if the vehicle's leak rate - in the vehicle is
excessive - and in this one it was somewhat less than 600 cc.
I think it was about 500 -
Dunkelman - 588.
Roman - I think your suggestion, Larry, was that it would be on
the outside of the vehicle.
Schirra - That I hadn't had a feeling for and I suspect this is
the only way you could get it in contrast to getting it from
within.
So I won't argue this point.
I am well aw~re of the
fact that it could be adsorbed and then passed off in this
environment.
Roman - John, (to Dr. O'Keefe) is it obvious that sunlight coming
through, in the upper atmosphere would be red if you are above
the dust layer?
QJKeefe - Well, when you look at the sun in th~ photographs
which were taken, it looks red.
Roman - · I see.
Schirra - The sunset is red.
Same old sun that we see here.
O'Keefe - Yes, but what you 1 d see on either side of it - flanking
it - is Maxfield Parish cloud, at least in the color photographs.
I think this is what Maxfield Parish went in for particularly.
He went in for very powerful colors - subtraction colors.
