U.S. poet laureate, Ada Limón was invited by NASA to write a poem to be engraved on the Europa Clipper spacecraft. That poem, "In Praise of Mystery: A Poem for Europa" launched to Jupiter and its moons on October 14, 2024. Reimagined as In Praise of Mystery, Limón's debut picture book, this luminous poem is illustrated by celebrated and internationally renowned artist Peter Sís. In Praise of Mystery celebrates humankind's endless curiosity, asks us what it means to explore beyond our known world, and shows how the unknown can reflect us back to ourselves.
