I wonder why they need two arrays for a couple day flight? I would think batteries would hold a charge for that long.
Oh well…it looks like it’s going to get there anyway.
From what the article mentioned about science experiments onboard, I would guess the the extra power is needed for those.
in case one fails. like it just did.
Batteries probably weigh considerably more than a couple solar arrays.
“ I would think batteries would hold a charge for that long.”
Planned obsolescence .
The manufacturer designs it so the new software update drains your battery too easy, to force you to buy the newest model .
