WATCH: Poet Laureate Ada Limón reads poem being sent to space on NASA's Europa Clipper mission

NEW YORK (AP) — A new work by U.S. Poet Laureate Ada Limón, written for an upcoming NASA mission to Jupiter's moon Europa, is a glance at outer space that returns back to Earth.

Watch the recitation in the player above.

Limón's "In Praise of Mystery: A Poem for Europa," which she read Thursday night during a ceremony at the Library of Congress, is part of NASA's " Message In a Bottle Campaign " as the aeronautics and space administration prepares for a years-long journey. The Europa Clipper is expected to launch in October 2024, with "In Praise of Mystery" engraved on the spacecraft.

The spacecraft will travel 1.8 billion miles to eventually orbit around Jupiter, where it will conduct flybys of the gas giant's moon, Europa. The moon's icy surface is believed to hide a vast ocean, considered to be one of the most promising habitable environments in the solar system.

"Writing this poem was one of the greatest honors of my life, but also one of the most difficult tasks I've ever been assigned," Limón said in a statement released through the Library of Congress. "Eventually, what made the poem come together was realizing that in pointing toward other planets, stars and moons, we are also recognizing the enormous gift that is our planet Earth. To point outward is also to point inward."

During a recent interview with The Associated Press, Limón said she struggled at first with the poem, explaining that because of its official nature she couldn't rely on her usual instincts. After working on more than a dozen drafts, she received invaluable advice from her husband, Lucas Marquardt, who urged her to write the poem is if it were personal, a "poem that you would write anyway."

"I think of all the times as a child that I would look down and find a whole universe in the grass, or in a small, watery wedge from the creek across the street from my house," she said. "But then I also think that that was in tandem with looking up at the moon."

The 7-stanza poem begins as a tribute to "the night sky inky/with black expansiveness," a sky we read as an "unerring book of the universe." But, Limón adds, treasures can be found below the sky.

"O second moon, we, too, are made

of water, of vast and beckoning seas.

We, too, are made of wonders, of great

and ordinary loves, of small invisible worlds,

of a need to call out through the dark."

Limón, 47, has been poet laureate since 2022 and was recently appointed by Librarian of Congress Carla Hayden to a second term, lasting two years. Her books include "Bright Dead Things" and "The Carrying."
