'A measurable, enormous global impact': Astronaut Chris Hadfield on why the true power of Artemis II could take decades to hit

With Artemis II complete, NASA is pushing ahead with plans to build a permanent human habitat on the moon, and retired Canadian Space Agency astronaut Chris Hadfield wants to make sure one crucial piece of technology is awaiting the future crop of lunar settlers: a guitar.

"We keep a guitar on the International Space Station ... and as we start to settle the moon over the next five or 10 years, we're going to need a musical instrument there," Hadfield told Live Science in an interview. "Music is really important. Even NASA, a very strict science and engineering organization, recognizes how important it is for mental health."
