The message has already been sent! Social Networking has
reached out to the stars.
In October 2008, members of the networking website Bebo
beamed A Message From Earth, a high-power transmission at
Gliese 581, using the RT-70 radio telescope belonging to the
National Space Agency of Ukraine. This transmission is due
to arrive in the Gliese 581 system's vicinity by the year 2029;
the earliest possible arrival for a response, should there be
one, would be in 2049.
Transmission of such a message from U.S. soil is a criminal
offense, I believe. Or at least, frowned upon.

Ok then - how about a Radio Transmission. I would assume we are doing
this. What would we send?
We gotta do something!

To The List Travel Club:
A 0.008c probe could be built tomorrow (got cash?). It
would take about 2600 years to reach the Gliese 581
system and maneuver through it and we could hope
the instrument packages would have survived.
Here's the real argument against primitive interstellar
probes: the "velocity" of technological advancement is
greater than the speed of primitive probes. In 200 years,
the 2600-year probe would be overtaken by a 800-year
probe. In another century, they would both be passed
by the "next-generation" system of propulsion, and so
forth. And by the time any of these probes could get there,
we might be able to go ourselves in a reasonable time
(by the ship's clocks).
On the other hand, we might be able to make a 100-year
probe by the end of the century. For now, we need to
concentrate on survey and data collection technologies.
For probe technology, I refer you to the 1973-78 study
by the British Interplanetary Society -- Project Daedalus.

The project is currently being designed as Project Icarus:
