Hurley carried out the Droplet Formation Examine within the Microgravity Science Glovebox (MSG), which evaluates water droplet formation and water stream. Hurley additionally carried out the Capillary Buildings investigation, which research using totally different buildings and containers to handle fluids and gases.

Hurley and Behnken labored on quite a few pattern switch-outs for the Electrolysis Measurement (EM) experiment, which appears at bubbles created utilizing electrolysis and has implications for quite a few electrochemical reactions and units. Each crew members additionally contributed photos to the Crew Earth Observations (CEO) examine. CEO photos assist document how our planet is altering over time, from human-caused adjustments – corresponding to city development and reservoir development – to pure dynamic occasions, together with hurricanes, floods, and volcanic eruptions.

Behnken carried out 4 spacewalks whereas onboard the area station with Expedition 63 Commander and NASA colleague Chris Cassidy. The duo upgraded two energy channels on the far starboard facet of the station’s truss with new lithium-ion batteries.
