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.

(February 19, 2025) -- NASA astronaut Don Pettit demonstrates electrostatic forces using charged water droplets and a knitting needle made of Teflon. This series of overlapping frames displays the unique attraction-repulsion properties of Teflon and charged droplets, similar to how charged particles from the Sun behave when they come in contact with Earth’s magnetic field. Highly energetic particles from space that collide with atoms and molecules in the atmosphere create the aurora borealis.
