The six-member Expedition 42 crew worked Dragon cargo transfers and science on the International Space Station Wednesday.
Commander Barry Wilmore conducted botany research and harvested plants grown for the Advanced Plant Experiments-03-1 (APEX-03-1). The thale cress plants are photographed and preserved in a science freezer for analysis on the ground.
NASA astronaut Terry Virts processed samples for the Coarsening in Solid Liquid Mixtures-2 (CSLM-2) experiment, which studies the processes that occur in materials for consumer and industrial products. He later unpacked more gear from inside Dragon.
Ground controllers are preparing the Canadarm2 and Dextre to remove the Cloud-Aerosol Transport System (CATS) experiment from Dragon’s exposed trunk and install it on a platform on the outside of Japan’s Kibo laboratory. CATS will observe aerosols in Earth’s atmosphere to understand the impacts to global climate and create a better model of the climate feedback process.
