Mars Ring details

This ring is no longer available as I became concerned about how difficult it would be to remove. I now only make rings from softer metals that could, in principle, be cut with wire cutters.

MOLA data forms the outer surface of the ring, modelling the topography of Mars between approximately 30 degrees north and south of the equator. Vertical scale is exaggerated by about 7 for clarity. Numerous surface features are visible, including Olympus Mons, the Tharsis volcanoes, Tharsis Tholus, Biblis Patera, Ceraunius Tholus, Noctis Labyrinthus, Hebes Chasma, Ganges Chasma, Valles Marineris, Eos Chasma, Xanthe Terra, Margaritifer Terra, Ares Vallis, the Watney triangle, Schiaparelli crater, Terra Meridani, Terra Sabaea, Huygens crater, Isidis Planitia, Syrtis Major, Libya Montes, Gale Crater, Elysium Mons, Albor Thous, Tyrrhena Terra, Hesperia Planum, Apollinaris Patera, and Pettit crater. Italic features may not be visible on smaller prints.

The inside of the ring consists of debossed icons of the Mars Pathfinder rover (Sojourner), the Mars Exploration Rover (Spirit/Opportunity), the Mars Science Laboratory (Curiosity), and a truncated hexa-octahedral magnetite crystal of the sort found in ALH84001 and the magnetotactic bacteria strain MV-1 - currently the strongest evidence in support of the hypothesis that life originated on Mars.

The ring is printed in high definition stainless steel (feature size 0.1mm) and may some require some burr removal with a small file for comfort.

There is a new design now available on request. The surface is an isometric conformal mapping of the entire surface of Mars, unwrapped like an orange peel. The interior has text "Hopefully not at the point of impact".
