How can I precisely chart the *absolute* positions and ship-relative
velocities of icy comets encountered on a forward pass... then try to
re-intercept them on a reverse pass, having turned my ship around?
That isn't necessary. Just plant a small transmitter on the comet; that will
give you directional information. If the transmissions and receptions are
accurately timed (pulsars make excellent clocks available to all) then the
distance to the comet can be easily calculated.

Thanks! That's a sound idea, but I think we will be *certain* of a
nice trail of comets stretching all the way to Alpha, long before the
mission is due for launch... projected at round 2200 AD... by which
time we will have filled all the interim experience gaps necessary
with adventures on the Moon and Mars!

Now, I was going to turn this thing into a cracking BIG SCREEN MOVIE,
if only I could present my script to some 'movie' agency!

Grim, you wouldn't happen to know of any contacts in the movie
business by any chance would you? I'll share the royalties if it
helps...! LOL..
