of gas like that the ambient pressure - the general ambient
pressure - is quite different from the pressure right around
your vehicle o
I still wonder whether you can get the pressure
up around the vehicle for the level where condensation takes
place"
I have been trying to persuade some people that the
condensation takes place before it leaves these ports of course
as it spreads out in space "
The pressure is certainly much higher
around the bottom of the heat shield, but I do not know whether
that is right or not"
Shoemaker -
Do we have any more questions on the airglow?
They are very usefulo
Dr o Liddel - We have two problems here o
One is the pressure and the
other is the rate of evaporation "
O'Keefe - That's trueo Once formed, they may not sublime out.
Question is how were they formed.
Schirra - I think there is one thing that we might bring into this
before we leave it unless there is a separate question on it o
The green- yellow~ almost a chartreuse, coloring of these particles,
I feel, did not permit you to see the edges of the particles as
well as they appeared when they were in the white band in the
sense of looking like frost particles o So they looked more like
blobs and· this is typical of fireflies themselves "
You can ' t defi ne
the size of the blob you see as green- yellow ~ but if you see a snow­
flake, which is white, you can very easily see its edges in a sense .
Not that you focus on them but you can visualize that they have
edges .
This is a point that I don't think I have made in the past,
