Laythe and Vall rotation periods?

[Deadpangod3]

So I'm planning a large mission to the Jool system, and I'm planning to land two rovers, one on Laythe and another on vall.

But my problem is making my rovers have enough electric charge to survive the night,

So I need to know their rotation periods and the units of electric charge I need, but the wiki doesn't say the rotation period, so I'm in the dark on this (pun intended)

Any help is appreciated.

The wiki does have their rotational period, under "physical characteristics". 52 980.879 s for Laythe (it's tidally locked, so same as its orbital period) and 105 962.09 s for Vall.

Ok, so how much electric charge would I need to keep my rovers alive?

Just put an RTG on the rover, or wait until the night is over so the rover can continue.

RTGs feel like cheating to me idk why, but I just hate using them unless its a very short flight

You shouldn't. Curiosity has 5kg of plutonium powering its RTG. It should last (with enough power to make it useful), for about 14 years.

So nope, not cheating. It's actually a tested practicein the real world of space exploration, whenever solar power may not be enough or not constant (IE: deep space or planetary surfaces)

It really all dependant on how much driving you'll be doing during that time. If you keep a small panel on top, you can just drive untill you exhaust your batteries, then recharge them in daylight.
