The European Planetary Science Congress ends today in Rome even as scientists and engineers on the astronautical side of things head for Prague, where the International Astronautical Congress convenes on Monday. I’ll be keeping an eye on events in Prague and wishing I could join the gathering of Tau Zero practitioners that will be taking place there — Marc Millis will be presenting four papers, and many of the Project Icarus team members are also making the journey, so we should be getting regular updates on matters interstellar.
Nor do I want to neglect the Royal Society meeting on extraterrestrial life, coming up early in October in Buckinghamshire in the UK. Emails from James Benford (Microwave Sciences) and Richard Carrigan (Fermilab) tell me both will be speaking at the session, which reminds me that it was way back in April that I promised more on Carrigan’s notions of interstellar ‘archaeology,’ a form of SETI that makes no assumptions about the originating civilization. It’s time to honor that pledge by looking at the kind of artifacts an advanced civilization might create that could be detectable.
