From Bob Irving
In his letter defending nuclear rockets
(4 August, p 51), George Maise seems
to ignore the fact that to build nuclear rockets in low-Earth orbit for missions
to outer space, you still need to get the nuclear material into orbit,
presumably in its highly enriched form. So it could easily end up strewn all
over the Earth if an accident occurs on the way up—not a happy
prospect.
