One of the two cameras was just completely clouded for a few
hundred· orbits and then gradually after a few hundred orbits it
improved a little bit o
Schirra - I need a little more flight time:
I ' m all for ito
Nordberg - We eliminated this by putting a sheet over it in
third stage and since then we have never had any troubleo
Schirra - Sure p that's ito
I am sure this is something we
can't let rest o We've got to cover these windows to protect
them from clouding during the transition to where we are now
to space itselL

In sun­

It is quite true that with an outflow
