iss072e097523 (Oct. 23, 2024) -- Where space science meets art! Using a blank, white laptop display as the illuminator, a polarizing filter, and the International Space Station's freezer, which sits at -140 degrees F (-95 C), NASA astronaut and Expedition 72 Flight Engineer Don Pettit grew thin wafers of water ice in microgravity. What results is colorful, fragmented ice crystals.
