NASA astronaut Jeanette Epps processes blood and saliva samples

iss071e414653 (Aug. 1, 2024) --- NASA astronaut and Expedition 71 Flight Engineer Jeanette Epps processes blood and saliva samples aboard the International Space Station's Harmony module. She stowed the specimens in a science freezer and the Kubik research incubator for future retrieval and later analysis. The weightless environment of the orbital outpost allows investigators to explore how living in space long term affects humans and gain insights not possible in Earth’s gravity conditions.
