When you look at the moon, what do you see?

Producer and artist Siddharth Khajuria encounters competing human imaginations for the moon. Starting with some of the earliest lunar maps, he works with moonlight to illuminate thornier questions about our own behaviour on earth. What motivates the desire to etch a name into the landscape?

The humanity woven through our modern map of the moon – Seas of Tranquility and Crises, Lakes of Death and Dreams, an Ocean of Storms – is the work of a 17th century Italian priest, Giovanni Battista Riccioli. Siddharth meets Riccioli’s poetic mapmaking in the context of a heated European race to name the moon’s many craters, mountains, valleys and maria.

From these celestial cartographers etching names into the first detailed lunar maps, to the Cold War era Apollo missions and commercially-fuelled landings that lie ahead of us, the story of humanity’s relationship with the moon is one of a growing intimacy.

Featuring astronomer and lunar biographer David Whitehouse, librarian at the Edinburgh Royal Observatory Karen Moran, space lawyer Frans von der Dunk, and a late night, torch-lit conversation between Siddharth and his eldest son.
