ABSTRACT:
This Progress Report covers the first six months (October 1977 to March 1978) of accomplishment of the JPL/LeRC advanced subsystems development task. It is intended as a means of publishing the results of the work on advanced concepts and disseminating the technology to industry. It is hoped that the open approach of NASA in providing easy access to all the results, procedures, and the data base developed in this task, and in opening the door for discussions with other organizations, will stimulate adaptation of the most promising concepts by industry.
