There are two possible answers to me. They are
(1) practical: we can get something useful
out of it, and (2) philosophical: exploring
things is what we do as humans.
For the first one, there are a few tempting
reasons to explore Saturn. Saturn is made of gas,
and mostly hydrogen. If we want to explore the
stars, Saturn may be a good stopping point to
refuel with hydrogen if we use that as a fuel
source. We could also potentially mine the
moons. One moon in particular, Titan, has a
dense atmosphere (like Earth) and even liquid on
the surface. So, some scientists think it might
have life on it, which would be important to
study. Also, Titan is a place we could possibly
build bases on for humans to live (details:

So, it could be a useful place for us
scientifically if we ever get off this planet.
Philosophically, exploring things is what we
do. It's like climbing a mountain. Many people
climb mountains because they feel compelled to
explore. That may not sound like a good reason,
but it historically has been valued. Also, any
time we explore new things, we get benefits that
we may not even have imagined. For example,
if Einstein hadn't thought of general
relativity, GPS systems wouldn't work
(complicated to explain why). Similarly, if we
hadn't gone to space we wouldn't have many
inventions that we use every day. These side
effects are really a fairly good reason to
