A Zero-Gravity Eyewash Tool for Astronauts

Don Pettit is an American astronaut who has previously spent over a year living on the International Space Station. He's scheduled to return in September for six months.

On X, Pettit educates the public about life and science in space. Recently, he posted this image of the emergency eyewash station used in low Earth orbit. A 2014 article on Phys.org describes how it works.

To ensure that the water goes where it is supposed to go and, equally important, not where it is not supposed to go, the water flows into goggles. The machine pumps the water in and then out of the sealed goggles.
