Similarly to the original post, it looks like NASA is accepting musical submissions to accompany it’s Lucy mission:

"Are you a musician – composer, performer, music educator, or student – inspired by exploration and discovery? Share your inspiration in your unique voice, and join with others to create the Lucy Soundscape, a public collection of original music inspired by NASA’s Lucy mission launching in 2021!
The Lucy spacecraft will carry robotic cameras to places no one has ever seen: the Trojan asteroids, remnants from the formation of our Solar System’s giant planets, like Jupiter. In an epic twelve-year voyage of discovery, Lucy – named for a fossil human ancestor – will visit seven of these prehistoric treasures that hold the lost tales about the origin of our solar system.
Lucy’s team of scientists, engineers, managers, and other professionals have many stories to tell, in many different voices, but some stories are told best through music! NASA invites composers, performers, music educators and students to add their voices to Lucy’s.
The Lucy Soundscape will be the collected original music of everyone who participates and shares their creativity with NASA and the world, all connected to each other through the Lucy Motif:

Lucy Motif - high version - (MP3 file)
The Lucy Team composed and adopted this three-note phrase as a symbolic “musical mission patch.”
Any original music, composed or improvised, instrumental or vocal, that uses the Lucy Motif in some way to express a feeling or tell a story of inspiration and discovery can be shared through the Lucy Soundscape. Through the combined creativity of participating artists, all starting from the same three notes, the Soundscape has the potential to become an evolving musical ecosystem that develops in unforeseeable ways as the mission itself develops and yields unforeseeable discoveries.
Add your creative voice and join the Lucy Soundscape!"
