A Simon Fraser University study reports that just a few days in simulated microgravity subtly altered blood clotting in women, prompting questions about whether current astronaut health monitoring would detect or mitigate such changes. The results raise concerns for missions lasting six months or longer.

Briefing
The study found measurable changes in women’s blood coagulation after only a few days in simulated microgravity, a potential early physiological response that could compound over missions of six months or more.
The results raise questions about the adequacy of current in‑flight health monitoring, coagulation screening, and countermeasure strategies for long‑duration missions.
This finding complements recent evidence of other structural and physiological effects from prolonged microgravity, including documented brain shifts and deformations and brain reshaping in long‑duration studies.
