People - Watch Astronaut Michael López-Alegría and Pianist BLKBOK Perform a Duet — from Space!

Astronaut Michael López-Alegría's latest mission is out of this world.

In what marked the very first time an astronaut in orbit has performed a duet with a musician back down on Earth, López-Alegría teamed up with pianist BLKBOK for a moving performance of the artist's song "STARS (AD ASTRA)."

Afterwards, BLKBOK—who was behind the keys in Florida, where he'd watched López-Alegría take off—performed, fittingly, Elton John's "Rocket Man," which he dedicated to the astronaut, 63.
