The gloved hands of NASA astronaut inside the Microgravity Science Glovebox

iss073e0759779 (Sept. 2, 2025) --- A top-down view inside the Destiny laboratory module’s Microgravity Science Glovebox shows the gloved arms and hands of NASA astronaut and Expedition 73 Flight Engineer Zena Cardman. She was processing bone marrow stem cell samples for the Microgravity Associated Bone Loss-B (MABL-B) experiment. The space biology investigation could help scientists better understand the molecular mechanisms behind space-caused bone loss and the natural aging process on Earth.
