Renowned astronomer Carl Sagan, known for his contributions to science and space exploration, left a lasting message for the first humans on Mars before his passing in December 1996. Sagan, a co-founder of The Planetary Society, believed in the importance of exploring Mars for potential signs of life.
Prior to his death, Sagan recorded a message specifically for the future inhabitants of Mars. This recording was transmitted to Mars and reached the planet on May 25, 2008, via NASA's Phoenix lander. The mini DVD containing Sagan's message remains on Mars, intended to endure for thousands of years.
