Inquiry about the Status of the PLANETOCOSMICS Tool

I recently came across a tool called PLANETOCOSMICS that is associated with GEANT4 and was intrigued to learn more about it. However, when I attempted to access the website that various sources have directed me to (, I encountered a “Not Found” error, indicating that the page is no longer available.

I am reaching out to see if anyone can provide some insight into what has happened with the PLANETOCOSMICS tool. Has it been discontinued, or is there a newer version or alternative available that I should be aware of?

I would greatly appreciate any assistance or guidance you can offer regarding this matter. Thank you in advance for your time and help.
