Flexibility to conduct a second Skylab mission would be retained until such time as NASA planning for the FY 1976 budget was complete. To accomplish this, NASA issued the following guidelines. Launch umbilical tower 2 would be retained in its present status for possible Skylab usage until a decision was made to prepare for a Skylab launch or to begin modifications for the Shuttle Program. Action would be continued to place in storage existing hardware (including appropriate backups and spares) required for conduct of a Skylab mission. The Skylab Program would fund the activities required to place the hardware in minimum cost storage and the storage costs through June 1974.

Studies had been conducted to determine an end-of-mission configuration for the Orbital Workshop and for maintaining the option of an OWS revisit at some future date. MSFC assessed the special deactivation requirements for the AM, MDA, and the Workshop required to establish a satisfactory, economical configuration. JSC made an evaluation of ground support monitoring and control options. The OWS would be left in a configuration that would permit a revisit at some future date without reactivation.
