Space Station Freedom payload operations in the 21st century
The modified approach to the accomodation of payload operations in light of both flight and ground systems changes to the operational concept for the Space Station Freedom is described. The challenges for the man-tended capability payload operations and those for the permanently manned capability are assessed. An overview of payload operations is presented including payload accomodations, operations modes, ground systems, the payload operations integration center, and the evolution from man-tended capability to permanent manning.

Space flight operations communications phraseology and techniques
Communications are a critical link in space flight operations. Specific communications phraseology and techniques have been developed to allow rapid and clear transfer of information. Communications will be clear and brief through the use of procedural words and phrases. Communications protocols standardize the required information transferred. The voicing of letters and numbers is discussed. The protocols used in air-to-ground communications are given. A glossary of communications terminology is presented in the appendix.

Improving the Spacelab mass memory unit tape layout with a simulation model
A tape drive called the Mass Memory Unit (MMU) stores software used by Spacelab computers. MMU tape motion must be minimized during typical flight operations to avoid a loss of scientific data. A projection of the tape motion is needed for evaluation of candidate tape layouts. A computer simulation of the scheduled and unscheduled MMU tape accesses is developed for this purpose. This simulation permits evaluations of candidate tape layouts by tracking and summarizing tape movements. The factors that affect tape travel are investigated and a heuristic is developed to find a good tape layout. An improved tape layout for Spacelab I is selected after the evaluation of fourteen candidates. The simulation model will provide the ability to determine MMU layouts that substantially decrease the tape travel on future Spacelab flights.

Payload Operations Control Center (POCC)
The Spacelab payload operations control center (POCC) timeline analysis program which is used to provide POCC activity and resource information as a function of mission time is described. This program is fully automated and interactive, and is equipped with tutorial displays. The tutorial displays are sufficiently detailed for use by a program analyst having no computer experience. The POCC timeline analysis program is designed to operate on the VAX/VMS version V2.1 computer system.
