The orbiting Expedition 52 trio continued exploring magnetized cell structures today and worked on advanced repair tasks. Also, a new crew is in Moscow getting ready for its launch in less than three weeks.
Astronaut Peggy Whitson was back at work Tuesday running the Mag 3D cell culturing experiment all day. She peered at magnetic three-dimensional cell cultures through a microscope, specifically looking at the borders of the biocell structures. The biocells were then stowed in a science freezer before being injected with magnetic 3D culture media. Mag 3D observations may improve cell and tissue culture capabilities and research on orbit.
Though the space station is an orbiting laboratory, it is also a home that needs regular maintenance. Flight Engineer Jack Fischer put on his repairman’s hat today replacing a failed water separator inside the Tranquility module. The water separator is part of the Common Cabin Air Assembly that controls the station’s temperature and humidity.
Three upcoming station crew members are spending their final week in Moscow before heading to the launch site in Kazakhstan on Sunday. The experienced space trio will launch to space aboard the Soyuz MS-05 spacecraft July 28 from the Baikonur Cosmodrome. Expedition 52-53 crew members Randy Bresnik, Paolo Nespoli and Sergey Ryazanskiy will live aboard the station for 4-1/2 months.
