Meanwhile I read somewhere that a small team of JPL scientists/engineers planned to add a plaque on the Cassini-Huygens spacecraft ... The project was known as the ' Diamond idea' ...
NASA and ESA initially liked the idea but it was cancelled
and replaced by a CD-ROM with signatures of Space enthusiasts and descendants from the Cassini-family!
