Ground controllers overnight remotely guided the Canadarm2, with its Dextre robotic hand attached, to deftly remove the CATS experiment from the SpaceX Dragon trunk. They then handed it off to the Japanese robotic arm for installation on the Kibo laboratory’s external platform. CATS, or Cloud-Aerosol Transport System, will collect data on the pollution, dust, smoke, aerosols and other particulates in Earth’s atmosphere to understand their impacts on global climate and create a better model of the climate feedback process.
Back inside the International Space Station, the Expedition 42 crew worked on an array of new and ongoing science and continued unpacking Dragon. There were eye exams as well as research into the effects of long stays in space on the human T-cells, which are a critical part of our immune system.
The crew also looked at how certain materials behave in space for the Coarsening in Solid Liquid Mixtures-2 (CSLM-2) experiment, which offers potential benefits for consumer and industrial products. In addition, they checked on the station’s fruit flies, which are also monitored by scientists studying their immune system as a model for a crew member susceptibility to disease in space.
