NASA astronaut Don Pettit is scheduled to return home in mid-April after a seven-month mission aboard the International Space Station as part of Expedition 72. Throughout his stay, Pettit contributed to research that benefits humanity and future space missions.
Pettit also shared what he calls "science of opportunity" to demonstrate how experimenting with our surroundings can help gain a better understanding of how things work. This understanding is perhaps enhanced when art, science, and microgravity come together.
Electrostatic Displays

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.
Specialized Equipment for Superb Science

NASA astronaut Don Pettit snaps an image of the hands of NASA astronauts Nick Hague, left, and Suni Williams inside the Life Science Glovebox, a facility at the International Space Station that separates the science from the scientists, thus protecting both from contamination.
