KENNEDY SPACE CENTER, Fla. -- Less than 24 hours before launch of STS-102, photographers capture the rollback of the Rotating Service Structure from around Space Shuttle Discovery on Launch Pad 39B. Poised above the external tank is the Gaseous Oxygen Vent Arm with the “beanie cap,” a vent hood. The RSS provides protected access to the orbiter for changeout and servicing of payloads. It is supported by a rotating bridge that pivots about a vertical axis on the west side of the pad’s flame trench. Space Shuttle Discovery is scheduled to launch March 8 at 6:42 a.m. EST on the eighth construction flight to the International Space Station. It carries the Multi-Purpose Logistics Module Leonardo, the primary delivery system used to resupply and return Station cargo requiring a pressurized environment. Leonardo will deliver up to 10 tons of laboratory racks filled with equipment, experiments and supplies for outfitting the newly installed U.S. Laboratory Destiny
