Space Shuttle Landing FacilityBy Marty McDowell/NASA
Space Shuttle landings at the Kennedy Space
Center are made on one of the largest runways in the world.
The runway is located 3.2 km (2 miles) northwest of the Vehicle Assembly
Building and is 4,572 meters (15,000ft) long and 91.4 meters (300ft) wide
- about as wide as the length of a football field. It has 305 meters
(1000ft) of paved overruns at each end and the paving thickness is 40.6cm
(15 inches) at the center.
The facility includes a 150 x 168 meter (490x550ft) parking apron and a
3.2 km (2 mile) tow-way connecting it with the Orbiter
Processing Facility. Located adjacent to the parking apron is a
Landing Aids Control Building (LACB) which supports landing operations and
houses operations personnel.
Located at the northeast corner of the parking apron is the Mate/Demate
device (MDD) used to raise and lower the orbiter from its 747
carrier aircraft during ferry operations. The open-truss steel
structure is equipped with hoists, adapters and movable platforms for
access to certain orbiter components and equipment. It also is equipped
with lightning protection devices. The MDD is 45.7 meters (150ft) long,
28.3 meters (93ft) wide and 32 meters (105ft) high.
The Shuttle Landing Facility is equipped with a number of navigation
and landing aids to assist Shuttle pilots in landing. There are four
sophisticated Microwave Scanning Beam Landing System (MSBLS) ground
stations - two located at each end of the runway - that provide elevation
and directional/distance measurement for landing approaches from the
northwest (runway 15) or southeast (runway 33). Equipment onboard the
orbiter receives the data from the MSBLS stations and automatically makes
any needed adjustments to the glide slope.
A Tactical Air Navigation (TACAN) system, located at mid-field off the
east side of the runway, is used by pilots to execute an instrument
landing approach to the runway. The TACAN has a range of 483 kilometers
(300 miles), and is received by the orbiter when it emerges from the
reentry blackout period. The final approach is guided by the MSBLS system.
Visual aids are provided by Precision Approach Path Indicators, known
as the PAPI system. They utilize arrays of red and white lights that, when
lined up properly by the pilot, will indicate the proper glide slope. A
ball/bar light system is used for inner glide slope information on final
approach - to inform the pilot whether he is on, above or below the glide
slope for an orbiter touchdown point marked on the runway.
A Recovery Convoy Staging Area, located just east of the runway about
midway along its length, houses trailers, mobile units and specially
designed vehicles that are used to "safe" the orbiter
immediately after landing for crew egress and transfer of the orbiter to
the Orbiter Processing Facility.
A specially constructed earthen mound just east of the Convoy Staging
Area contains bleachers, press facilities and a Public Affairs control
room to support invited guests and press coverage during orbiter landings
at the Kennedy Space Center.
