'Space Art': Astronaut Don Pettit's Water Ice Wafers | International Space Station

NASA Astronaut, Artist & Flight Engineer Don Pettit at work

NASA Astronaut Don Pettit: "Science, or should I say Nature, has a way of presenting surprising beauty if one is willing to look."

"Science and Art, or Art and Science; related subjects where it really doesn’t matter which comes first. So I have access to a freezer kept at -95 degrees centigrade (-140 F). What would you do with such a freezer in space?"

"I decided to grow thin wafers of water ice for no more reason than I’m in space and I can. Plus, I wanted to see how the freezing front behaves in 0g (without gravitational buoyancy, how does the freezing front push the tiny bubbles around). Here is one frame from a whole series. I photographed the ice . . . between crossed polarizers where I used a white (blank) laptop display as the illuminator/polarizer in conjunction with an analyzer (polarizing filter) I strategically packed in my bag of personal effects."
