Question 02/99
INTERSTELLAR TRAVEL
In 1960 Bussard proposed an interstellar vehicle that would collect
its fuel from interstellar medium. A large scoop would pick up protons
present in space, and the protons would be fed into a fusion reactor where part
of their mass would be converted into kinetic energy. How big would the scoop
have to be in order to produce a constant 1g acceleration
for a 3500-ton vehicle?
