It looks like 80% Weather chance the Atlas 5 will launch Thursday.
A United Launch Alliance Atlas 5 rocket is on the pad at Launch Complex 41 after a morning rollout from a nearby assembly building at Cape Canaveral Air Force Station.
Standing 19 stories tall on its mobile launcher platform, the Atlas 5 was pushed out to the pad by two powerful transporters. The one-third-of-a-mile move began just after 10 a.m. and was completed about a half-hour later.
The Atlas 5 is scheduled to blast off during a launch window that will extend from 9:37 p.m. to 11:42 p.m. Thursday. Its payload: Six experimental military satellites designed to test advanced defense technologies.
