A 6" aperture is plenty for viewing Jupiter (and Saturn)
With all things being equal (sky conditions etc) you will see the four largest moons and the G.R.S. with a 60mm scope, approx 90X is needed.
You will need Astronomy 2007 or a suitable planetarium program to show you when the G.R.S will be facing Earth.
The bigger the aperture will allow greater detail to be seen.
I hope this helps to answer your questions.

Many thanks for your help in advance.
