I had no idea there was any art on the moon, I was thrilled to find out about Fallen Astronaut. I guess you could almost call it a site-specific installation, but it certainly is an open air gallery with a fine piece of commemorative minimal sculpture – remembering all those who have died in service of this cause. It seems a poignant and touching tribute, and a very exciting discovery for me. There is some controversy surrounding the art – but it’s exciting to think of a piece of art in the far reaches of the cosmos.
