"Carl Sagan's Final Message to Future Martians"

Shortly before his death, Carl Sagan, a prominent astronomer and science communicator, recorded a message for future astronauts who would set foot on Mars, expressing his support for the exploration of the Red Planet and the potential reasons for human presence there. The recording, sent to Mars by The Planetary Society, arrived on the planet in 2008 and remains on the surface on an archival silica-glass mini-DVD, serving as a lasting tribute to Sagan's advocacy for space exploration.
