BoingBoing tells us:

Madeleine Robins called this picture of ISS astronaut Tracy Caldwell Dyson watching the spin far below, “The perfect cover for the perfect unwritten/unread SF novel I wanted to read when I was thirteen.” Exactly right.

Damn right, BoingBoing.

The above image was taken in late September from the ISS’s Cupola window bay. Dr. Dyson is a lead vocalist in the band Max Q.

There’s an astronaut band out there and no one told us?

This won’t do, Internet. Stop keeping these need-to-know bits of information a secret.
