Re: AO-40: spinrate ?



Man Oh Man is that good news.  I can now stop
turning blue.  The stability predictions (proclamations?)
had no component in them that I could detect
for extremely elevated ionosphere due to a very
active sunspot maximum.

No explanation came with Karl's message and
I don't think anyone else has provided one.

There are two components to the interaction
of the atmosphere with any body.  One is what
we all know as drag.  The other is lift.  Karl and
the team are reorienting the spacecraft so
that the sun angles are good for power generation
and we bias the body towards lift.


Fingers firmly crossed,
