The purpose of this paper is to examine the Manned Maneuvering Unit (MMU) Rescue Study that is being conducted in the Systems Engineering Simulator (SES) at the Johnson Space Center, Houston, Texas. The study explores the possibility of rescuing a man-overboard from the Space Station Freedom (SSF) using the MMU. The details of the study as well as some of the interesting problems that arise are discussed and a mathematical development of the equations that govern the behavior of two orbiting bodies is included.
