10 microseconds is nothing...that's a signal of 100 kHz.
AM radios can handle that, no problem -- and presumably so
can more sophisticated equipment. Of course it helps if
the signal is actually periodic... :-)

Heck, one might even be able to count the pulses on one's computer,
which is running at 3 GHz nowadays (if it's new).

As for Cassini orientated correctly -- I rather doubt it isn't.
That is to say that the beam antenna Cassini is using will probably
receive signals from the Moon as easily as from the Earth.

The divergence of Moon from Earth at Saturn's distance is approximately
3/100 of a degree. The main issue is transponder sensitivity.

I'll admit to not being all that qualified to tackle this
problem, but presumably a neutron star is going to have
a boundary, and I'm wondering how fuzzy a boundary at
this point. If a neutron is perfectly incompressible the
neutron star in free space will indeed be a true sphere
for the most part (I'm thinking of a rather bizarre planet
made of nothing but cat's eyes :-) ).

But even neutrons can shift around if enough gravitational
force is available, leading to a neutron star that looks
a bit like an egg than a sphere (though it would require
another similar egg close by). It's all a matter of
finding the lowest energy level.

I have a dumb question. In light of the notions expressed heretofore,
how long would it take for two stars of, say, 5 times Sun mass
and distance between mass-centers twice the star radius (which means
that were they rigid spheres they'd be rolling/touching one another)
before they fuse to become a single star?
