A British contribution to the evolution of space technology

This submission is in the form of a commentary on the work of the applicant in the field of space technology, accompanied by, and related to, a selection of published papers on various facets of his subject. There are actually several scores of papers by the applicant which have been published internationally on the subject, but to avoid the rather impractical submission of the amount of paper that this would involve, only some forty of the most relevant papers are listed in Appendix A by title, date, occasion and their published format. Of these the commentary relates to a key selection which, in the opinion of the applicant, will permit the most sensible linked sequence in order to demonstrate the evolution of technology with which the applicant has been concerned in this field.
