The effects of spaceflight on the human body are complex and largely harmful over both short and long term. Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia). Other significant effects include a slowing of cardiovascular system functions, decreased production of red blood cells (space anemia), balance disorders, eyesight disorders and changes in the immune system. Additional symptoms include fluid redistribution (causing the "moon-face" appearance typical in pictures of astronauts experiencing weightlessness), loss of body mass, nasal congestion, sleep disturbance, and excess flatulence. A 2024 assessmen…

ESA VIVALDI Dry Immersion Microgravity Simulations Induce Increases in Immune Biomarkers Associated With Physical and Psychological Stress, and Sex-Specific Factors.. With future manned space projects involving missions of unprecedented duration, multisystem deconditioning induced by spaceflight could seriously affect the well-being and health of astronauts. Safe and easily determined in-flight biomarkers are therefore needed to monitor health status. In this study, we simulated space deconditioning with a 5-day dry immersion (DI) of 18 healthy women and 19 healthy men and evaluated the effects of this protocol on three biomarkers: the neutrophil-to-lymphocyte ratio (NLR), the granulocyte-t…

For All Mankind is an American science fiction drama television series created by Ronald D. Moore, Matt Wolpert, and Ben Nedivi and produced for the Apple TV streaming service. The series dramatizes an alternate history depicting "what would have happened if the global space race had never ended" after the Soviet Union succeeds in the first crewed Moon landing ahead of the United States. The title is inspired by the lunar plaque left on the Moon by the crew of Apollo 11, which reads, in part, "We Came in Peace for All Mankind". The series stars an ensemble cast including Joel Kinnaman, Michael Dorman, Sarah Jones, Shantel VanSanten, Jodi Balfour, Wrenn Schmidt, Sonya Walger, and Krys Marsha…
