This image shows the DVD provided by The Planetary Society to the Phoenix mission, which contains 250,000 names of people who signed up to send their names to Mars. It also contains "Visions of Mars," messages to future Martian explorers, science fiction stories and art inspired by the Red Planet. The DVD is mounted on the deck of the lander, which sits about one meter above the Martian surface, visible in the background.
