Polaris Dawn astronaut performs 'Star Wars' song in music video broadcast from space (Video)

Polaris Dawn astronaut and violinist Sarah Gillis released a new music video from space this morning.

Just yesterday (Sept. 12), Gillis was one of two Polaris Dawn astronauts to conduct a historic spacewalk, the world's first commercial spacewalk. During the hour and 46-minute spacewalk, Gillis and Polaris Dawn mission commander and financier Jared Isaacman tested SpaceX's new EVA suits, which the company says will help enable future missions both in Earth orbit and further out in space, possibly to the Moon or Mars.

Early Friday (Sept. 13), Gillis and the Polaris program released the video, titled “Harmony of Resilience,” on X (formerly Twitter). “As we travel our beautiful planet Earth on this five-day mission, we wanted to share this special musical moment with you. Bringing together global talent, this performance symbolizes unity and hope and highlights the resilience and potential of children everywhere,” Gillis says in introducing the video.

The song in the video, “Rey's Theme,” was written by John Williams for Star Wars: The Force Awakens and performed by Gillis aboard the Crew Dragon starship on the Polaris Dawn mission. In the video, Gillis can be seen playing the solo violin part of the song, alongside videos of orchestras performing the song in studios and on sound stages.

“Inspired by the universal language of music and the tireless fight against childhood cancer and disease, this moment was created in hopes of inspiring the next generation to look to the stars,” the Polaris program wrote on its website. The video was created in partnership with St. Jude Children's Research Hospital, for which the Polaris program raises money throughout the mission, and El Sistema USA, a program that aims to promote music education “for positive societal impact.”
