My name is Edward Hirst.
I'm the Deputy Mission System Manager
on the Juno Project.
Well, Jupiter and its moons are really
kind of a mini solar system.
Um, it has 64 moons.
It's a fairly big planet.
And the science community likes to go back
to Jupiter to investigate that whole system
as a model for our solar system.
And what they learn there, they can apply
for the origin of the planets
and the origin of Jupiter and its moons.
What we're interested in knowing
about Jupiter itself is, uh,
more about the interior of the planet.
Um, whether it has a solid core,
whether it's a liquid metal core, um,
where some of the elements, the more classical elements,
like water, lie within the planet.
It's that sort of, um, information that gives
the science community, uh, just more data that will allow
them to understand how Jupiter came about.
It's a fairly big planet.
Um, it's, there's 50 Ear-, Earth radii,
there's 50 Earths that fit across it.
There's like 2,000 Earths that would fit inside of it.
And, um, it's just so big and massive
and it's mostly gases.
But really what's inside,
what's at the center, is unknown.
And, um, the experiments
we're doing will help unravel that mystery.
