Engineers used the Jupiter encounter to test the spacecraft's instruments and operations. During the flyby, Cassini captured incredible images of the gas giant and its larger moons in a science plan that was coordinated with Galileo observations.
Launch: Planned for August 2011; Jupiter arrival: Planned for August 2016
Juno will survey Jupiter from a polar orbit, carrying a suite of instruments designed to study the planet's interior.
It will investigate the existence of an ice-rock core; determine the amount of global water and ammonia present in the atmosphere; study convection and deep wind profiles in the atmosphere; investigate the origin of the Jovian magnetic field; and explore the polar magnetosphere.
B) Ask students what they would like to find out about Jupiter or any of the Galilean moons. What questions would they design a spacecraft to answer? What sorts of instruments would help them answer these questions? C) Remind students where to look for Jupiter at the current time, then exit the dome and regroup outside. V) Conclusion (5 minutes) A) When all have exited, review the key concepts of the lesson. Why are the four largest moons of Jupiter called the Galilean moons? What other achievements is Galileo known for? What role did the Galilean moons play in our understanding of the universe? What do scientists hope to learn from future missions to Jupiter or its moons?
