SciNoFi guest-blogger Susan Karlin got a quick photo of this tattoo on the arm of Comic-Con treasurer (and creator of the Comic-Con iPhone app [link redirects to iTunes store]) Mark Yturralde. Yturralde is such a NASA fan that he has created a permanent shrine on his right arm to all the astronauts who gave their lives for the space program. (The astronauts are grouped into the three fatal American space missions: Apollo 1, Challenger, and Columbia.) He says, "I'm hoping there won't be anymore deaths. So I purposely spaced out the names so there wouldn't be enough room to add more." For any curious readers of the Loom, we're already checking with Yturralde if he wouldn't mind if we submit a pic of his tattoo to Carl's Science Tattoo Emporium.
