In the weightlessness on International Space Station I placed a sphere of water with an air bubble on a speaker cone, then drove it with acoustical waves from the speaker.

This created a series of standing nodes and anti-nodes that responded to the frequency and amplitude. A zero gravity

Annular solar from International Space Station taken on May 20, 2012 when I was East of Kamchatka Peninsula, Russia. The deep umbra of the Moon's shadow makes a stark contrast to the surrounding white clouds.

Star trail time exposure from my third mission to International Space Station. Solar panels blur into the exposure, creating a ghostly afterimage.

City lights streak to the right, and disappear in rural plots to the left, dividing the image into a black and gold mosaic of human presence.

Data mining ISS imagery in an unusual way.

Nathan Bergey, then a visiting scholar at Portland State University in Oregon, plotted on a blank map of Earth, the location of the Space Station at the moment each of more than 1.1 million astronaut photographs were taken. A new
