I saw a YouTube video which made an interesting point. You can estimate the power requirement of the balloon’s payload by looking at the sixteen solar panels dangling beneath it. Those panels would produce far more power than would be needed for imaging or signals intelligence. So, what the balloon may have been carrying is a rather deep mystery.
Well the BOTTOM of a balloon isn’t the best place to capture the sun ;-)

Not anymore. It’s down and collected.
