Hurricane Ian is prompting NASA to move its Artemis I moon rocket off the launch pad and into shelter, adding weeks of delay for the lunar-orbiting test flight.

NASA isn’t speculating when the next launch attempt might be, but it could be off until November. It means a number of performers won’t be at the launch as scheduled including renowned cellist Yo Yo Ma.

After the news, the 66-year-old tweeted a version of ‘Somewhere Over the Rainbow’ dedicating it to those who need a bit of comfort.

The Philadelphia Orchestra accompanied by Yo-Yo Ma were set to perform “America the Beautiful.”

Jack Black, Chris Evans, Keke Palmer  were to make appearances during NASA’s live broadcast. Josh Groban and Herbie Hancock had the honors to perform the national anthem.
