The unmanned probe Mariner IX launched on 30 May 1971. Images sent back of the planet's surface revealed an incredibly rocky landscape reminiscent of the lunar surface. After completing its final transmission on 27 October 1972 it had photomapped 100% of the planet's surface. This early Mars globe would have been one of the first to incorporate Mariner IX imagery.
