[17] Fischer and Whitson set up a seedling growth botany study[8] to investigate the effects of light and microgravity on Arabidopsis thaliana.

[18] Fisher was also the subject of a Vascular Echo study[19] that examined changes in blood vessels and the heart while in space and their recovery back on Earth.

[36] Fyodor Yurchikhin maintained the life support system on the Russian side of the station by preplacing pumps and hoses and re-pressurizing the cabin.

[37] Jack Fischer replaced a failed water separator inside the Tranquility module that was part of the Common Cabin Air Assembly that controls the stations humidity and temperature.
