Programmer's manual for the Mission Analysis Evaluation and Space Trajectory Operations program (MAESTRO)
The Mission Analysis Evaluation and Space Trajectory Operations program known as MAESTRO is described. MAESTRO is an all FORTRAN, block style, computer program designed to perform various mission control tasks. This manual is a guide to MAESTRO, providing individuals the capability of modifying the program to suit their needs. Descriptions are presented of each of the subroutines descriptions consist of input/output description, theory, subroutine description, and a flow chart where applicable. The programmer's manual also contains a detailed description of the common blocks, a subroutine cross reference map, and a general description of the program structure
Launch window analysis of satellites in high eccentricity or large circular orbits
Numerical methods and computer programs for studying the stability and evolution of orbits of large eccentricity are presented. Methods for determining launch windows and target dates are developed. Mathematical models are prepared to analyze the characteristics of specific missions

Popper's views of theory formation compared with the development of post-relativistic cosmological models
Thesis (Ph.D.)--Boston UniversityThis dissertation confronts contemporary physical cosmology with
Karl Popper's standards of scientific method and theory construction.
To the degree to which there are differences, an attempt is made to
criticize the major cosmological models in the light of Popper's analysis
and, in turn, to explore revisions necessitated in this analysis
by the unique problems of cosmology.
As background, the major facets of Popper's work are presented
in detail: his falsifiability criterion for demarcating scientific
theories from metaphysics, his hypothetico-deductive method, and his
rejection of induction. Then the origins of general relativity and
its competitors are analyzed both as explanatory background to modern
cosmology and so as to reveal the history of certain problems pertinent
to Popper's scheme: for instance, the use of arguments from simplicity,
the ideas of the utility of analogy and models, and the relation of
theory to reality. Finally, the great variety of evolutionary, fundamentalistic,
and steady-state models available for study is explored
in detail as to presupposition and methodology so that their distinctives
are revealed and a basis for comparison with Popper's suggestions provided. [TRUNCATED
