Nice picture of a barred spiral, but apart from that, what's the
point you're trying to make? Are you proposing a probe to be launched
to travel around the galaxy in the opposite direction to the solar
system, so as to complete a survey of the galaxy in half the time that
it could otherwise be done?
That would be around 100 million years.
But if a million years from now Earth started to launch
"generation ship" type exploration efforts that travelled at an average
of 0.01c (3000 km/s) then in a further 100,000/0.01= 10 million years
the generation ships would be on the far side of the galaxy and the
"Galactic Drifter" probe would be 11/100th of the way around the
perimeter.

it's much more in that inclination.]
