Status report on shuttle program.

Abstract

Following a brief summary of previous work, major attention is given to Phase-B extension, the Request for Proposal (RFP), the selected configuration and associated activities, and the future. NASA extended Phase-B contracts to examine other options that might lower peak annual funding and decrease program risk. Most of the discussion deals with the shuttle and orbiter systems. The efforts of the shuttle program in the past year have seen the completion of numerous trade studies and the selection of a prime shuttle contractor.
