   A while back there was a discussion of various ways to dispose of
high-level radioactive waste, e.g., launching it into the Sun.  Ignoring
for a moment the ecological, political, and moral issues, does anyone
recall the relative launch energy costs of--

    a) direct ascent from Earth to Sun

    b) into Sun via inner planet gravity assist

    c) into Sun via outer planet gravity assist

    d) direct ascent to Moon

    e) direct ascent to Venus

    f) into solar system escape trajectory?

   As I recall, (e) and (f) were favored, but what is the rank order?
Thanks.      --Eric Hoffman
