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 and Beacon etc... do some magnetorquing to improve attitude. Something like this was done when AO-10 was hit by the last rocket stage, spinning the wrong direction with sun directly on top and almost no power... Unfolding the solar panels would give very high power only when they are oriented towards the sun. With folded solar arrays, all panels around the satellite can still see the sun around it's spin axis. Only when it shines on top or bottom, we will have problems...

In the current configuration (or the last known config) of the vehicle does the vehicle have sufficient solar illumination to "spin" and maintain the DC busses without a battery?
