Gut Microbiome Dysbiosis in Simulated Microgravity: A 90-Day Longitudinal Analysis
Analog microgravity environments produced measurable shifts in Firmicutes/Bacteroidetes ratios within 21 days of simulated weightlessness, with significant implications for nutrient absorption efficiency in long-duration crews.
Bacteroidetes abundance decreased 31% vs. baseline; dietary fiber supplementation (12g/day inulin) partially reversed dysbiosis by day 42.
Double-blind crossover study, n=24 healthy adults, 6-week head-down tilt bed rest protocol. 16S rRNA sequencing at days 0, 21, 42, 90. Dietary intake controlled via standardized ISS-analog meal protocol.
Bone Mineral Density Preservation Through Calcium-Fortified Freeze-Dried Rations: ISS Expedition 68 Data
Crew members receiving calcium-enhanced ration packs (1400mg Ca/day) showed 23% lower trabecular bone loss at the lumbar spine compared to standard ration controls after 180-day missions.
1400mg/day calcium with co-administered Vit K2 (200μg) showed synergistic protection; effect size Cohen's d = 0.74.
Retrospective cohort analysis of DXA scan data from ISS Expeditions 65–68. Dietary logs cross-referenced with galley manifest records. Statistical analysis via mixed-effects linear regression.
Psychological Palatability and Monotony Index in Repeated Exposure to Identical Meal Protocols
The Monotony Index, a novel composite score of sensory fatigue and meal acceptance, declined 44% after 30 days of identical meal rotation in isolation chamber studies, correlating significantly with caloric intake reduction.
Meal variety ≥14 unique items per rotation cycle maintained Monotony Index above clinical threshold; below 8 items, voluntary caloric intake dropped 18%.
Prospective isolation study, HERA (Human Exploration Research Analog) Campaigns 5–7. n=32 participants, 45-day isolation. Daily palatability ratings (VAS scale), caloric intake measured, psychological battery administered weekly.
