CAPE CANAVERAL, Fla. – The Ground Systems Development and Operations Program is overseeing efforts to create a new multi-user firing room in Firing Room 4 in the Launch Control Center at NASA's Kennedy Space Center in Florida. The main floor consoles, cabling and wires below the floor and ceiling tiles above have been removed. Sub-flooring has been installed and the room is marked off to create four separate rooms on the main floor. In view along the soffit are space shuttle launch plaques for 21 missions launched from Firing Room 4. The design of Firing Room 4 will incorporate five control room areas that are flexible to meet current and future NASA and commercial user requirements. The equipment and most of the consoles from Firing Room 4 were moved to Firing Room 2 for possible future reuse. Photo credit: NASA/Ben Smegelsky

CAPE CANAVERAL, Fla. -- In Firing Room 4 of the Launch Control Center at NASA's Kennedy Space Center in Florida, Shuttle Launch Director Mike Leinbach oversees the countdown to the launch of space shuttle Atlantis on its STS-135 mission to the International Space Station. Atlantis with its crew of four; Commander Chris Ferguson, Pilot Doug Hurley, Mission Specialists Sandy Magnus and Rex Walheim, lifted off at 11:29 a.m. EDT on July 8, 2011 to deliver the Raffaello multi-purpose logistics module packed with supplies and spare parts for the station. Atlantis also will fly the Robotic Refueling Mission experiment that will investigate the potential for robotically refueling existing satellites in orbit. In addition, Atlantis will return with a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems. STS-135 will be the 33rd flight of Atlantis, the 37th shuttle mission to the space station, and the 135th and final mission of NASA's Space Shuttle Program.

CAPE CANAVERAL, Fla. – In Firing Room 4 in the Launch Control Center at NASA’s Kennedy Space Center in Florida, the legacy consoles, Launch Processing System and cabling that once supported the Space Shuttle Program have been removed. The Ground Systems Development and Operations Program is overseeing the construction in progress on a multi-use control room that will support NASA and commercial launch needs. The design of Firing Room 4 will incorporate five control room areas that are flexible to meet current and future user requirements. The equipment and consoles from Firing Room 4 are being moved to Firing Room 2 for possible future reuse. Photo credit: NASA_Dimitri Gerondidakis

CAPE CANAVERAL, Fla. – Workers at NASA's Kennedy Space Center in Florida carefully place a new window on the Firing Room in the Launch Control Center. New, hurricane-rated window systems for the four Firing Rooms and the vestibule areas between Firing Rooms 1 & 2 and Firing Rooms 3 & 4 are being installed. In order to avoid operational impacts the new windows are being installed on the outside of the existing windows, enclosing the space formerly occupied by the louvers. The old windows will remain in place until the new windows are completely installed and leak tested. This approach will continue to keep the firing rooms from being exposed to the elements.
