NASA astronaut Don Pettit shows us how to change a Nikon Z9 lens in zero gravity aboard the International Space Station

Don Pettit changes his camera lens in zero gravity in the International Space Station.

There are a few things to consider when changing a lens, such as having a clean, flat surface so as not to drop it, and minimizing the risk of dust entering the sensor.

But it’s a slightly different situation for astronaut Don Pettit, who recently shared a video to X (formerly Twitter) showing how he changes the lens of his Nikon Z9 in zero gravity aboard the International Space Station (ISS).
