Why Isn't My 2002 Saturn SL2 Starting?

I've got a 2002 Saturn SL2 that wont start. When I turn the key the first time, nothing happens. Then when I try turning it again I hear a very light clicking noise. All the basic electronics--the overhead light, the radio, the dash lights--operate fine, so I was thinking that the problem was the starter. Could it still be the battery if these electronics are working? Or could it be something else entirely?

Thanks
