- Satellites on a long orbit (as someone else suggested) sound good, but a
- billion-year orbit is one *heck* of a long time. It might also be hard to find
- them when they swing back. I don't think you could guarantee that any power
- source would be active after so long.
-
- My best shot would be to draw your message on the Moon. Use finely divided
- carbon or something, and draw it in big letters. If you want to be cute, make
- the message fractal in nature, so that each segment of the message is made up
- of smaller messages. Even after crater formation you should be left with enough
- to convey the message.
-
- If you've got the resources, build a *big* artificial satellite, perhaps even
- one that orbits the Sun. If it's large enough you should be able to give it a
- non-decaying orbit, one that won't be perturbed by long term (planetary
- gravitational pull) or short term (asteroids hitting it) interactions.
