As part of her tenure as U.S. poet laureate, Ada Limón has written "In Praise of Mystery," which will be engraved on the Europa Clipper spacecraft that launches to Jupiter and its moons in October 2024. Published here as 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.

Ada Limón is the author of six books of poetry, including The Carrying, which won the National Book Critics Circle Award for Poetry. Her most recent book of poetry, The Hurting Kind, was shortlisted for the Griffin Poetry Prize. She is the 24th Poet Laureate of The United States and the recipient of a MacArthur Fellowship. As the Poet Laureate, her signature project is called You Are Here and focuses on how poetry can help connect us to the natural world.

Peter Sís has received the Robert F. Sibert Medal, three Caldecott Honors, and a Sydney Taylor Honor. He was the first children's book creator to receive a MacArthur Fellowship, and won the 2012 Hans Christian Andersen Award. He lives in Hudson Valley, New York.
