In October, NASA will embark on a captivating mission to Jupiter’s moon Europa with a spacecraft named Europa Clipper.

This mission carries a unique and thoughtful payload: a special message to the stars, including over 2.6 million names from people around the world.

This initiative follows NASA’s long-standing tradition of sending messages of hope and connection into the vastness of space, aiming to inspire and unite us all.

Europa is a fascinating celestial body, harboring a vast ocean beneath its icy surface, believed to contain more water than all of Earth’s oceans combined. The intrigue surrounding this distant moon and its potential for life has sparked the imagination of scientists and dreamers alike.

To honor this connection, NASA has crafted a special artifact to ride aboard Europa Clipper: a metal plate that serves as a symbolic bridge between Earth and the mysteries of Europa.

At the center of this artifact is a poem titled “In Praise of Mystery: A Poem for Europa,” penned by U.S. Poet Laureate Ada Limón. Her words, etched in her own handwriting, alongside a silicon microchip bearing the names of millions, encapsulate humanity’s innate curiosity and our quest for understanding the unknown.

This microchip, artfully integrated into an illustration of a bottle amidst Jupiter’s moons, echoes the theme of NASA’s “Message in a Bottle” campaign, inviting people worldwide to be part of this historic journey.

The artifact, crafted from durable tantalum metal, is adorned with art that emphasizes our deep-rooted connection to water, an essential element for life as we know it.

One side of the plate showcases the word “water” in 103 languages, converted into visual waveforms that spread out from a symbol representing water in American Sign Language.

This diverse collection of languages and the universal sign for water symbolize the shared importance of this element across cultures and species.

This gesture is reminiscent of the Voyager spacecraft’s Golden Record, which carried the sounds and images of Earth to depict the diversity of life and culture on our planet.

Europa Clipper’s message aims to do the same, weaving together elements of science, technology, art, and education to illustrate our connection to the cosmos and the shared essence of life across the universe.

As Europa Clipper embarks on its 1.6-billion-mile journey to orbit Jupiter, it will closely examine Europa, seeking signs of habitability in its subsurface ocean, icy crust, and thin atmosphere.

The mission is a testament to humanity’s relentless pursuit of knowledge and our desire to explore the unknown.

The spacecraft’s design includes a commemorative plate that not only carries messages of hope and unity but also serves a practical purpose by sealing an opening in the metal vault that protects the mission’s sensitive instruments from Jupiter’s harsh radiation.

Etched onto this plate is the Drake Equation, a mathematical formulation that has guided the search for extraterrestrial life, as well as references to radio frequencies used in the search for cosmic messages, symbolizing humanity’s attempts to communicate across the stars.

The plate also honors Ron Greeley, a pioneer in planetary science, whose vision laid the groundwork for the Europa Clipper mission.

His legacy, along with the collective efforts of countless scientists and dreamers, propels this mission forward, embodying our shared quest for discovery and understanding.

As the Europa Clipper prepares for launch from NASA’s Kennedy Space Center in Florida, the excitement and anticipation build.

This mission, decades in the making, represents more than just a scientific endeavor; it’s a message of hope, a testament to human curiosity, and a bridge to the mysteries waiting in the vast ocean world of Europa.
