The giant spacecraft on its way to Jupiter's icy moon

So it's possible they also come from other things.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

I'm going to make something up right now.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

I'm making this up.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

If the star goes supernova, I don't know what happens to the planets on the end or if the star turns into a white dwarf.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

Maybe there are other ways for a rogue planet to form, but that's the way that I know.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

And you're right.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

Since they're not near a star and going around it in a repeatable fashion for Kepler to measure that dip in brightness, Kepler cannot find rogue planets like that.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

Yeah, that's actually not a bad analogy.

So we definitely, being able to fold up the solar arrays is an integral part of the original design.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

If you imagine, stick your arms out to the side, if you had about three elbows, then you could fold your arms in very nicely.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

That's how it happens.

Conversations

And we had long conversations about when you fold it up and you have the cells that are on the outside, should those be the cells that are power producing or should you fold it so that the power producing ones are on the inside in case something happens to hit them?

Conversations
The giant spacecraft on its way to Jupiter's icy moon

Do you protect them or do you need to make power?

Conversations
The giant spacecraft on its way to Jupiter's icy moon

There's a whole bunch of trades that are like that.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

Ours, we did power side out so that if somehow it took longer for the arrays to deploy than we thought, you had some power while you're trying to figure out what's going on.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

And this is one of the pieces where the spacecraft needs to be autonomously set to do all the things.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

We have very large batteries on the spacecraft.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

Unlike some missions where you could launch and you'd only have like a couple of hours before you had to get the arrays out or you would run out of power,

Conversations
The giant spacecraft on its way to Jupiter's icy moon

We had many hours.

Conversations
The giant spacecraft on its way to Jupiter's icy moon

I think something like 19 hours because we're here at the Earth and cells are out.
