Nicole Sharp<p><strong>Ice Without Gravity</strong></p><p><a href="https://arstechnica.com/space/2024/10/nasa-astronaut-don-pettit-is-a-giant-nerd-and-were-all-luckier-for-it/?__readwiseLocation=" rel="nofollow noopener noreferrer" target="_blank">Astronaut Don Pettit</a> is back in space, and that means lots of awesome microgravity experiments. Here, he grew thin wafers of ice in microgravity in a -95 degree Celsius freezer. Then he took the ice wafers and photographed them between crossed polarizers, creating this colorful image. The colors highlight different crystal orientations within the ice and give us a hint about how the freezing front formed and expanded. I can’t wait to see more examples!
