During the Space Shuttle Program, the Flight Dynamics Officer was responsible for the selection of Shuttle Landing sites for a variety of scenarios including nominal End-of-Mission (EOM), various Ascent Abort scenarios (Trans-Atlantic Abort Landing – TAL and Abort-Once-Around – AOA), and other potential emergency landing scenarios.

In coordination with the Landing Support Officer (LSO), worldwide runway complexes, that met basic requirements of runway length and navigational aids, were compiled into a list of potential Shuttle landing sites. Current mission requirements, Shuttle trajectories, and weather reports from around the world were combined to select the best landing opportunity in real-time. These landing sites were loaded into the FDO’s Deorbit Opportunities Processor (DOPS), which provided an at-a-glance view of upcoming landing opportunities.

The map graphics you see below were generated by the LSOs during the mid-1990s using the technology at hand. Obviously, more modern mapping capabilities would make these look so much better, but -THE TRENCH- will continue to provide these maps as an archive of how it was done during the Shuttle Program of the 1980s and 1990s.

World Map

In this graphic, all world-wide designated Space Shuttle Landing Sites are identified. The sites in the two blue boxes are defined in the other two images below.

These sites included Primary Landing Site (PLS) as well as Emergency Landing Site (ELS) choices.

The three PLS sites were EDW – Edwards Air Force Base, NOR – Northrup, White Sands Space Harbor, and KSC – Kennedy Space Center.

ELS sites ranged from those also used for Trans-Atlantic Abort Landing (TAL) sites as well as true “Emergency” sites (Hao Atoll and Easter Island in the South Pacific). Hao and Easter Island had originally intended as “TAL” sites for launches planned from Vandenberg.

CONUS Map

In this graphic, sites in the Eastern Continental United States (CONUS) are displayed.

The details in this map show the sites up the coast of the Eastern United States. This was used, primarily, to outline the possible “intact abort” sites during high-inclination Space Shuttle launches.

Kennedy (KSC) was, of course, the launch facility, but was also the Return-to-Launch-Site (RTLS) abort landing site. RTLS was a very dangerous, and thankfully never executed, abort scenario. It was simulated many many times, however, and had the crew and the MCC needed to perform it, they were ready.

Sites up the East Coast were all on high-alert during a launch that might have needed them at a moment’s notice.

Europe and Africa Map

In this final graphic, sites in Europe and Northern Africa are displayed.

The primary role of the sites in Europe and Northern Africa were to support Day-of-Launch (DOL) Abort landings.

The selection of the sites were specific to the launch inclination. More easterly launches (28.5 degree inclination) would have resulted in lower latitude potential abort landings, while the Mir/ISS launches (51.6 degree inclination) and higher would have engaged more of the northern/European sites.

Post-launch, these sites were also kept on hold for potential ELS opportunities.
