    Cardiac Stem Cells:  In support of the ongoing Cardiac Stem Cells investigation, the crew changed out the media in one of the BioCell Habitats in the Microgravity Science Glovebox (MSG).  Cardiac Stem Cells investigates how microgravity affects stem cells and the factors that govern their activity, in order to clarify the role of stem cells …

  • Aging and Heart Research Lead Station Science Today

    Expedition 52 explored the aging process in space today and measured the lighting conditions on the International Space Station. The crew is also getting spacesuits ready for an upcoming Russian spacewalk. Flight Engineer Peggy Whitson swapped out stem cell samples today inside the Microgravity Science Glovebox for the Cardiac Stem Cells study. The experiment is …

  • Crew Preps for Solar Array Jettison and Dragon Departure

    An experimental solar array demonstration was jettisoned while the Expedition 52 crew continued preparing the SpaceX Dragon for its release on Sunday. The three crew members also studied how microgravity impacts their bodies. Following a week of successful science operations on the experiment for the Roll-Out Solar Array (ROSA), attempts to retract the array were …
