Scientific paper

A probe sent to explore the Galaxy could be accelerated through repeated flybys past neighboring stars, a technique used in the recent Pioneer and Voyager programs. The probe must cross the paths of the stars in directions opposite the path of each star and end on a path to the next nearest star. The changed trajectory must be at least 90 deg from the approach trajectory. A numerical model is devised for calculating the number of flybys past massive objects which must be performed for a probe to reach a specified velocity. The model shows that acceleration of a probe up to 10,000 km/sec would take about 100,000 yr in the solar neighborhood and 100 yr at the center of the Galaxy. A flight to the fringe of the Galaxy would therefore take 2 million years.
