I am pleasantly amused by the interest in all probability of a dead bird. Can you imagine the explosion in interest and excitement on this bb if it ever came back. It would be nice but we can only play with L/S modes on the occasional AO-51.

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... 73s Peter Rocky Jones wrote: > Peter. > > 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? > > Robert WB5MZO > > ------------------------------------------------------------------------ > Hotmail: Powerful Free email with security by Microsoft.
