Abstract:

The purpose of the study was to determine in general the conditions for which an astronaut could be recovered to a spacecraft in a circular orbit of 107.56 miles using a tetherline. Simultaneous differential equations were solved with a digital computer for a large number of recovery trajectories varying initial conditions and recovery parameters. Two types of tethering systems were examined. It was found that if the astronaut was initially at rest he could be safely recovered from up to 130 ft away, but that if he had certain initial transverse velocities the safe operating radius was reduced drastically.
