Don Korycansky,
an astronomer at California's Lick Observatory, realized that
this idea is, in fact, possible. And he wrote a paper about it,
which you can download from
his
website
. Or
read
the abstract
online.
Even
NASA has used the science behind it
Many of NASA's
missions have made use of the principle called "gravitational
slingshot." Recently, the Cassini spacecraft flew by Venus,
Earth and Jupiter in order to be accelerated out to Saturn.

Science
because you can
This isn't
the first time scientists have spent time and money pondering
something, simply because it's possible. Right now someone's thiniking
about how to make Mars livable, and the Exploratorium's Paul Doherty
was paid to devise a spacecraft that could, but never will be
built.
See for yourself how it would work
All you need
are a tennis ball, basketball, and some room to bounce.
