Quick question: There was an earlier failure a few weeks ago. In that case, the computer failure came first due to a software glitch. This caused the solar panels to drift out of alignment. This statement above implies that the second failure was different--that a power failure caused a computer failure. Is this the case, or were the two failures the same and this report is wrong?
