Hey everyone! Welcome Active Galactic
Videos.
My name is Taylor, and today I will be
bringing you five facts about
the Juno mission in under five minutes.
So let's get started!
Juno won't be the first spacecraft to
reach Jupiter. A total of eight
spacecraft have at least flown by
Jupiter as part of their mission.
The Galileo spacecraft was the first to
study Jupiter from orbit in 1995.
It studied Jupiter for over seven years, and during its time in orbit, it was able to
study the planet's composition and
atmosphere. And now Juno will enter
Jupiter's orbit and hopefully answer all
the questions previous spacecraft left us with.
Juno will map out the gravitational
and magnetic fields of Jupiter.
It will accomplish this by using its
onboard magnetometer and radio receiver.
These allow us Earthlings down here to
determine what might actually lie
underneath the cloudy gaseous atmosphere of Jupiter.
We should be able to tell whether or not
Jupiter has a solid core in its center,
and with any luck, what it's made out of.
Juno was launched on an Atlas V rocket.
Because the funding for space missions is so
tight, and going to space is extremely expensive,
It wasn't in the budget to build a brand
new rocket just for Juno.
Luckily, the Atlas V has a perfect launch
record, and even though it's a great rocket,
it's not powerful enough alone to get
Juno all the way to Jupiter.
Back in 2013, Juno performed
a successful flyby of…
Earth!
Juno used Earth's gravity as a kind of
slingshot to help increase its velocity
Giving it the boost it needed
to get it all the way to Jupiter
Knowing more about the composition
of Jupiter's atmosphere
will tell us a little bit more about what our 
Solar System was like when it was
still forming.
Juno was equipped with infrared
cameras and radiometers. These devices
are going to penetrate hundreds of
kilometers down into the clouds of Jupiter,
Giving us an indication of how
much oxygen is in the atmosphere.
This will tell us how much water is in
Jupiter's atmosphere.
The amount of water in Jupiter's
atmosphere will either confirm or disprove
our current theories about the formation
of the Solar System.
So, funny story…
Jupiter got its name from Roman
mythology. Jupiter is the king of the
gods, and each one of its four largest
moons (also known as Galilean moons)
are all named after one of Jupiter's lovers.
But none are named after his wife…
hmmm…
One myth tells of Jupiter and enshrouding himself
in clouds to hide his mischievous behavior…
But his wife Juno was suspicion,
and she broke through the clouds to see
what he was up to.
Now the Juno spacecraft is about to peer through the
clouds of Jupiter to see what's going on.
