At NASA Kennedy Space Center in Florida, this view, taken from the top of the 355-foot-tall mobile launcher at Launch Pad 39B, illustrates the close proximity of the pad to the Atlantic Ocean in the background. The structure in the center of the photo is one of three lightning masts at the pad. Media representatives are taking the 21st Century Ground Systems tour which also includes the Vehicle Assembly Building, a crawler-transporter parked on the crawlerway, and the Launch Control Center's Firing Room 1. These facilities and equipment will be used to prepare and launch NASA's new Orion spacecraft on the Space Launch System heavy-lift rocket.

The tour was arranged as part of prelaunch media activities for the agency's Mars Science Laboratory (MSL) launch. Liftoff of MSL aboard a United Launch Alliance Atlas V rocket from Space Launch Complex-41 on Cape Canaveral Air Force Station is planned during a launch window which extends from 10:02 a.m. to 11:45 a.m. EST on Nov. 26.
