This week we turn our attention to the giant planets of the outer solar system. These massive worlds are nothing like the terrestrial planets we’ve studied so far. In this discussion, you will learn a little more about the largest of these planets by choosing to discuss what we have learned from missions to either Jupiter or Saturn.

Choose one of the following topics:

The Juno spacecraft was launched on August 5, 2011, and reached Jupiter on July 4, 2016. What do we hope to learn from this specific Jupiter mission? Why is this information important to our understanding of our solar system?

or,

What have planetary scientists learned about Saturn and Saturn’s moons from the Cassini mission?
