Mission brief
ONE MILLION MESSAGES.
ONE PHYSICAL MOSAIC.
ONE TARGET: MARS.
The engineering concept, qualification path, public cargo references, and limitations behind the long-term physical mission.
Beyond the digital archive
THE JOURNEY DOESN'T END ONLINE.
1,000,000 messages become one Earth Mosaic.
Our target: the earliest available compatible commercial Starship cargo mission to the surface of Mars.
When the archive reaches one million humans, we plan to manufacture the Earth Mosaic: one million physical micro-tiles representing every Mars Tile in the founding archive.
Our goal is to engineer and qualify the completed Earth Mosaic as an ultralight payload and pursue transport aboard the earliest commercially available SpaceX Starship cargo mission to the Martian surface that can accept our payload.
SpaceX currently states that Starship cargo flights to the Martian surface for research, development, and exploratory missions are planned no earlier than 2028.
No launch reservation or partnership with SpaceX currently exists.
