Description
English: iss072e096196 and iss072e098100 (Oct. 23, 2024) -- NASA Astronaut Don Pettit views thin wafers of ice under polarized filters on the International Space Station. Pettit conducts “science of opportunity” using station’s MELFI freezer to understand the behaviors of freezing water under microgravity conditions without gravitational buoyancy. This ice wafer was photographed between a polarized filter and a laptop display used to illuminate and cross-polarize the thin ice, giving a colorful image highlighting the fragmented crystals. This is a composite image of iss072e098100 and iss072e096196.
