Just as advanced western scientists have no interest in going on biology field trips to remote parts of the world to study lesser species.
Traveling a few hundred miles to see a creature you can stand a few feet away from, touch, and study /AND/ traveling for millions of years, never seeing the fruit of your labor so that your great X 1,000 grandchildren might be able to reach a planet they can walk around on in an air tight suit for the rest of their lives, then send a signal back to earth which will take 20 years to reach. That's a whole new "field trip".
And if it might give you some peace, there are thing called machines that can be built to contact other civilization without sacrificing your hypothetical children.

Most things fail before they succeed.
[NB I wouldn't consider the Project Orion approach "existing" technology, it hardly got off the drawing board and was never tested with anything other than chemical explosives on a very small scale].
