You may enjoy this week’s episode from the Cool Worlds Podcast all about leaving evidence of our civilization for alien visitors, or even a future civilization here on Earth. The episode, “Nick Searra – Alien Communication, Golden Record, Future Relics,” covers a lot of ground from the Pioneer and Voyager missions to the idea of placing time capsules about our civilization on the Moon or even within the orbit of Jupiter.
The guest is Nick Searra, who is Founder and Executive Directory of the Interstellar Foundation. The Interstellar Foundation has a clear mission – to create messages that represent the diversity and creativity of humanity, inspire future generations of explorers, and communicate with potential extraterrestrial life.
On the site, you an read about the Foundation’s Aspire One, which was an effort to create a lunar record to preserve Earth’s cultural and scientific heritage on the Moon. Preserved records include UNESCO archives, World Heritage images, and other scientific, historical, and cultural material. This message is already on its way to the Moon via this week’s launch of the Blue Ghost lunar lander.
A second messaging mission, Aspire Two, is now in development.
The podcast discussion and related website basically cover the continuation of work stared by Carl Sagan with the launch of Pioneer 10 back in 1972. I recommend you check out both of them.
