<\/a>More human research, including how astronauts move around in microgravity as well as the effect of weightlessness on vision, packed the science program aboard the International Space Station<\/a> on Thursday. The seven-member Expedition 67<\/a> crew also continued its ongoing focus on life support, orbital plumbing, and electronics systems maintenance.<\/p>\n The lack of an up and down reference while living in microgravity affects how astronauts manipulate and grip objects. Researchers want to get a closer understanding of that behavior to keep astronauts safe in the differing gravitational environments of deep space travel, planets, moons, and asteroids. NASA Flight Engineers Bob Hines<\/a> and Jessica Watkins<\/a> took turns seated inside the Columbus laboratory module on Thursday for the long-running GRIP experiment<\/a>. The duo gripped and maneuvered a specialized device in response to pre-programmed stimuli so scientists can gain insights into a crew member\u2019s cognition and perception during spaceflight.<\/p>\n Hines would go on to orbital plumbing duties filling water containers in the Unity module<\/a>. Watkins wrapped up her day installing radio frequency identification (RFID) readers inside Unity. The installation work is part of the RFID Smart Sensing<\/a> study that seeks to improve inventory accuracy and item location on the station.<\/p>\n ESA (European Space Agency) Flight Engineer Samantha Cristoforetti<\/a> checked radiation detection hardware and collected microbe samples from the area around the Veggie<\/a> space botany facility for analysis. NASA Flight Engineer Kjell Lindgren<\/a> stowed biology research hardware and then tested the station\u2019s new toilet system located in the Tranquility module<\/a>.<\/p>\n Eye checks were back on the schedule on Thursday for Commander Oleg Artemyev<\/a> and Flight Engineer Sergey Korsakov<\/a>. The duo took turns scanning each other\u2019s retinas using medical imaging hardware with real-time support from doctors on the ground. The eye exams help researchers understand how weightlessness affects vision and the shape of the eye. Flight Engineer Denis Matveev<\/a> spent his day servicing Russian life support gear and stowing hardware for disposal inside the ISS Progress 80<\/a> resupply ship docked to the Poisk module<\/a>.<\/p>\n Learn more about station activities by following the\u00a0space station blog<\/a>,\u00a0@space_station<\/a>\u00a0and\u00a0@ISS_Research<\/a>\u00a0on Twitter, as well as the\u00a0ISS Facebook<\/a>\u00a0and\u00a0ISS Instagram<\/a>\u00a0accounts.<\/p>\n Get weekly video highlights at:\u00a0http:\/\/jscfeatures.jsc.nasa.gov\/videoupdate\/<\/a><\/p>\n Get the latest from NASA delivered every week.
