Re: Bravo to the command team!



My earlier message contained a misinterpretation
of Karl's announcement.  While it is true that
as the perigee lowers, we would have more
trouble maintaining attitude,  the perigee lowering
is occurring because of thrust being developed.

The eccentricity is pretty large due to the long
burn and as a percentage of apogee velocity,
a small amount of thrust can do a big change
at the other end,  increasing the eccentricity
even further.    I do not understand how we
are getting away with leaking this stuff away
without further damage but I am one person
that is extremely pleased to accept favors that
nature grants us.  I only hope that there is
enough mass loss left to significantly lift the
perigee without causing further electronics
damage.
