We were there a couple of years ago on lauch day. They were open but certain areas were shut down for that day or were shutting down early. You als do have the oppurtunity to purchase a pass to get you closer to the launcg pad to see the the launch but it is not refundable if they abort the launch that day. Hopefully this helps but again this is going on what we experienced a couple of years ago. Before the Columbia incident.
