Hi Samudra et all,
very interesting article and links you've sent out.

Hi Robert,
that's indeed the big question... We do not know in which attitude the
spacecraft is.. is it still spinning very slowly or tumbling? What is
the Solar-ß-Angel?
If the S/C has a good orientation to the sun and the battery opens, than
there should be enough power to operate the IHU an
Hi Gordon,
such a fuse would not prevent a battery from an internal short-cut in
one or more cells... that's in fact what happened to AO-40.
Also you have to make such a "failsafe" feature really fail safe, so
that it does not hit you in the back if it fails..
These kind of things, like Watchdogs

Hi Michael and Alan,
I can only repeat what Alan already said...
Work on P3-E is continuing and we are busy looking for launch
possibilities and other ways for financing it, i.e. on coat-tails of the
P5 Mars Mission.
This is our top priority at the moment and that's why you may not have
heard so

Hi Domenico, et all,
OSCAR-10 (P3-B) used the same 400N engine as OSCAR-13 (P3-C) and
OSCAR-40 (P3-D).
For P3-E we have a 200N motor from EADS Astrium, the same one which is
used on the European ATV...
